The class is composed of nine females and twelve males. Eighteen students are sophomores and three students are juniors. Thirteen students are gifted academically. In this unit students will explore the characteristics of quadratic equations and functions, learn the different ways to solve quadratic equations/functions, and learn how to graph quadratic equations. This unit is taught after the unit on Irrational and Complex Numbers, and the unit following this unit will be Variation and Polynomial Equations. Section II: Contextual Factors The students in this course are considered academically gifted. Because this is an honors class, the pace of this class is faster than the college prep course. The class consists of mostly sophomores, and their last math course was Geometry Honors. Also, two of the three juniors’ previous math class was Geometry Honors. One of the three juniors is taking Algebra II Honors for the second time. With that in mind, I will have to make sure that the student who is repeating this class for the second time is making connections to what he learned before. In the last unit, students scored very well on the unit test, so I think that these same group of students, given that they study and try to understand the material will score well on the final test. This unit in is the “meat” of Algebra II. I expect students to struggle with this unit to some degree because it will be their first time ever seeing many of the concepts that will be presented in this unit. However, I still hold high expectations for this group of students, and I expect for them to work hard and perform well on assessments. One other thing that I need to keep in mind with this group of students is that, even though they are honor students, their Algebra I foundation is very weak. They are missing a lot of key concepts, such as graphing things on a coordinate plane, as well as some simple solving for variables. Some things that I need to think about are that there is a late start day one day during unit, and there is also a day in which we have early dismissal for parent conferences. Another factor that may affect student learning is that this unit is taught during the production of Hairspray, as well as other dance performances. Many of my students will be participating in these extracurricular activities, causing them more focused on other things after school than working on math. Section III: Part A-Unit Objectives Correlated Unit Objectives Standards/Expectations 1. 2. IA-3.3 Carry out a procedure to solve quadratic equations The student will solve quadratic algebraically (including equations. factoring, completing the square, and applying the quadratic formula). The students will solve quadratic word problems. 3. The Students will graph quadratic equations. 4. The student will discriminant of a equation. find the quadratic 5. The student will write quadratic equations from given roots. IA-3.5 Analyze given information (including quadratic models) to solve contextual problems. IA-1.3 Apply algebraic methods to solve problems in real-world contexts. IA-1.6 Understand how algebraic relationships can be represented in concrete models, pictorial models, and diagrams. IA-1.5 Demonstrate an understanding of algebraic relationships by using a variety of representations (including verbal, graphic, numerical, and symbolic). IA-3.4 Use the discriminant to determine the number and type of solutions of a quadratic equation. IA-3.6 Carry out a procedure to write an equation of a quadratic function when given its roots. Section III: Part B-Assessment Plan Pre-Assessment – The pre-assessment will be a list of questions that the students can answer based on things that will be taught during the lesson. Some students will be able to answer most of the questions, will some student will not be able to answer any. This will guide my teaching because the questions that will be asked will cover a standard or an objective for the unit. The questions that the students “score” poorly on will be stressed more throughout the unit. For each question correct, the student will earn 1 point for a max of 14 points. Post-Assessment – The post-assessment will be a unit test that will cover many of the objectives covered in this unit. I want the test to be a fair assessment of what the students have learned in the unit. The test will be scored according to the point value of the question, for a max of 100 points. Another post-assessment that will be given will be the exact pre-assessment questions. I will give this as a way of seeing the growth of the student. This is also my way of assessing the student knowledge on question they saw before the unit, now after the unit, just in case they don’t score will on the unit test, I will still be able to see that the students did learn some of the objectives and standards. Other Assessments – Other assessments for this course will be in the form of quizzes throughout the unit after a section has been taught. Quizzes are accord according to point value of each question, with a max of 100 points. Section III: Part C-Analysis of Pre-Assessment The pre-assessment was a questionnaire with six questions. The questions were based mostly off how to solve quadratic formulas, its roots, and the graph of parabolas. The total point value of the questionnaire was 14 points, 1 point for each answer. Number of students per score Pre-Assessment Scores 5 4 3 2 1 0 0 0.5 1 1.5 2 3 4 5 6 Points Earned On Pre-Assessment The above graph shows points scored on the pre-assessment, to the number of students. Zero is the lowest number of points scored on the pre-assessement, while six points was the highest number of points scored. I think that this shows that the students really don’t know much about the concepts in this unit, so this is going to allow me to teach the most of the students something new. Some of the answers were close answers, or it looked like the some of the students had an idea of what was being asked on the pre-assessment, but were unclear with their answers. Because of this, I hope that in my teaching I am able to claifiy some of the unclear answers they gave, so that the concepts are more concrete in their minds. The student who scored the highest, is the daugther of a math teacher, but she also is repeating this course for the second time. Section III: Part D-Instructional Plan Unit Objectives Type of ActivityWhole/Pairs/Small Group/Individual Assessment Item Materials/Resources #2 & #4 from PreAssessment Completing the square and Quadratic Formula Pairs and Whole Discriminant Whole, Pair, and Individual #5 from PreAssessment Textbook, Smartboard Notes Word Problems Whole, Pair, Individual #11 and #12 on Unit Test Textbook, Smartboad Notes Write equations from given roots Whole, Pair, Individual Quiz #10 from Unit Test Textbook, Smartboard Notes Quiz 8-#1-4 Text book, Smartboard Notes #1 & #2 from Unit Test The strategies used in this unit are whole group learning, pair learning, and individual learning. I think this will benefit the students because it allows the students to see a concept taught, and then it allows the students to either work in pairs or individually to solve problems. Section 7.1: Completing the Square – This section will be taught in conjunction with Sections 7.2 and 7.3. There will be whole group learning, and then students will work pairs or in individually to work on the concepts in of this section. Students will also have independent work by way of homework. [Standard IA-3.3] Section 7.2: Quadratic Formula – This section began after the last unit’s test, however, this section was retaught when the unit actually began so that it was taught in conjunction with Sections 7.1 and 7.2. The students worked at their desk to complete a worksheet that explained how to use the quadratic formula and had ten quadratic equations to be solved. After this section was taught, it was revisited so that the word problems from this section could be taught. [Standard IA-3.3] Section 7.3: The Discriminant – This section was taught during Sections 7.1 and Section 7.2. This section was taught with more whole group learning and pair learning. The students used previous homework problems to understand the discriminant of quadratic equations. [Standard IA-3.4] Section 7.4: Equations in Quadratic Form – This section was taught in a whole group setting, and the students were given the opportunity to work on a few problems independently and the problems were discussed after they were given a chance to work on them. [Standard IA-3.3, 3.5] Section 7.5: Graphing y – k = a(x – h)2 – This section taught with whole group learning. Because the concepts of this lesson are more difficult than most of the sections so far, this section was taught at a slower pace. The students were given independent work for homework and the problems were discussed the next day. [Standard IA-1.5] Section 7.6: Quadratic Functions – Again, because this was the first time the students have seen this concept, I went a little slower, making sure that they understood the concept before moving on. Some of the concepts of this section used concepts form the completing the square section, so I was able to revisit those concepts, and build on them in this section. Students were given homework for independent practice. [Standard IA-4.2] Section 7.7: Writing Quadratic Equations and Functions – This section was going to be taught in two parts, however, that didn’t go according to planned. I taught this section to the class, and then had students work in pairs to figure out equations to given roots. Afterwards, this I taught the word problems from this section, and allowed students to work independently on them for homework. [Standard 3.6] Algebra II Honors – Unit Guide Chapter 7 – Quadratic Equations and Functions (Algebra and Trigonometry Structure and Method-Book 2) IA-1.3 Apply algebraic methods to solve problems in real-world contexts. IA-1.5 Demonstrate an understanding of algebraic relationships by using a variety of representations (including verbal, graphic, numerical, and symbolic).

Previous Night’s homework (Section 7-4) PART OF LESSON DETAILS & SPECIFICS Go over homework from previous night (Section 7.4) Answer any questions from the previous section. Have students complete the quiz on section 7.2 and 7.4. Ask students what the graph of quadratic equations look like and its name. Students should say a parabola. Ask the students what they know about parabolas and if they’ve graphed them before. Tell students that today’s lesson is to have students ANTICIPATORY SET graph quadratic functions. Ask student if they know the parent function/equation for a quadratic formula, and what the parabola looks like. Show students the parent function y = x2and its graph. Explain that this is the bases for all quadratics, and that the lesson today we will see how we move the parabola depending on a, h, and k. Show students the quadratic graphing form equation for quadratics. y – k = a(x – h)2 Ask students what they think the a does the graph. Show examples like y = -x2, 2 , and y = 2x2. Ask them to tell the difference between the graph, and how it changes from the parent function. ( |a| > 1 – narrow, 0 < a <1 – wide, a > 0 – opens up, a < 0 – opens down) LEARNING ACTIVITIES PART: PRESENTATION OF INFORMATION AND MODELING Ask students what they think the h does to the graph. Show examples like y = (x – 3)2, and y = (x + 5)2. Students should realize that the h moves the parent function horizontally, and when h > 0 it moves to the right, when h < 0 it moves to the left. Ask students if the know what the k does to the parent function. Show examples like y – 3 = x2, y + 6 = x2. Students should see that the k affects the y – intercept of the graph, and moves the graph vertically along the y-axis. k < 0 moves down, k >0 moves up. Tie all the concepts together by using the graphing form, y – k = a(x – h)2. Tell students that the vertex is (h, k), and that the axis of symmetry is x=h, the same h that comes from the vertex. Example y – 2= 2(x – 4)2. Students should recognize that (4, 2) is the vertex, the graph will be narrow since a = 2, and the graphs opens upward. Students should also recognize that the graph moves up 2 units and moves to the right 4 units. Work on oral exercises (page 330 1-8) as a whole group and ask students to tell what the a, h, and k are, the vertex, and the axis of symmetry. After students have mastered this skill have students, ask students how to find the x and y intercepts. Plug in zero for x when finding the y intercept, and plug in zero for y when finding x intercepts. Go back to the orals, and have students match the graphs with the questions based off what they know about the vertices and the x- and y intercepts.

Previous Night’s homework (Section 7-5) PART OF LESSON DETAILS & SPECIFICS Hand back and go over quiz 7.2, 7.4 Go over homework from previous night (Section 7.5) Answer any questions from the previous section. ANTICIPATORY SET Give students Chapter 7 Study guide for their test. Asks students what makes an equation a parabola. Students should say that the squared term in the equation or function makes that equation or function have a parabolic graph. Begin by asking the students if they can graph f(x) = 2(x – 3)2 + 1. The student mostly like will say that they can graph it, but ask them if they notice something different about this equation/function that is different from other ones they’ve seen before. They should say that instead of it having y = or 0 = , that it’s an f(x) = equation. Ask students what f(x) can be changed to. F(x) = y. LEARNING ACTIVITIES PART: Explain to student that they must change f(x) to y first before thinking about graphing PRESENTATION OF the function. This now changes the function to an equation. Then have student write INFORMATION AND the equation in quadratic graphing form by moving the 1 to the other side and MODELING changing it to y – 1= 2(x – 3)2. Students should recognize this form from the last lesson, being able to identify the vertex (3, 1), the axis of symmetry (x=1), and they look of the graph. Ask students if they can graph, f(x) = 3x2 – 6x +1. They can, if they change the function to an equation. Now it is y = 3x2 – 6x +1. Ask students if the equation is in the quadratic graphing form. It isn’t, so what do they think we need to do to the equation to make it look like y – k = a(x – h)2. Ask student what y – k = a(x – h)2 reminds them of. (Completing the square). Therefore students need to change the standard form of the quadratic equation into the quadratic graphing form to graph the function. This would be a great time to review completing the square. However, this time instead of 0 = the equation, it is now y = the equation. The new equation will be y – 2 = 3(x – 1)2. From this from, students should recognize the vertex and the axis of symmetry. Student should also know how to find the x- and y- intercepts. After doing this, tell students that there is a much easier way to find the vertex of a function without having to complete the square if they remember the formulas for h and k. Tell student that if they know h, they don’t need to remember the formula for k, since h, is x, and by find y, students know the plug x back into the equation. This is used with h(x) and k(y). Have students find the vertex of g(x) = 6 + 6x – 3x2 by using the formula for h and k. Show the students how to use the formula for both h and k, and then show them that once they find h, they can plug in that value for x, to find the k value. Discuss domain and range of parabolas with the students. (Example 3 from page 334). Tell students that the domain of every parabola is all real numbers, and the range of parabolas is from how low or how high the parabola goes along the y axis. Use Example 3. CHECKING FOR UNDERSTANDING GUIDED PRACTICE INDEPENDENT PRACTICE CLOSURE Ask students what they think the max or min of a parabola is based off sketched drawings of parabolas that is open upward, and one that is open downward. (upward min and downward max). As students what they think makes a parabola have a max or min. Students should remember that a flips the graph upward or downward. So if a > 0 then the function or equation has a minimum value. If a < 0 then the function has a maximum value. Students should also recognize that the max or min value comes from the k value from the vertex. Ask students if they are understanding what is being taught or what questions they may have. Have student work the orals (page 335 #1-6) to tell if the function as a max or min and at what value. Homework – Page 336 # 1 – 29 odd Asks students what the first thing they should do in graphing functions. Also ask students the process of changing a function in standard form to quadratic graphing form. Ask students the formulas for h, k… Ask students how to determine the min or max value of a parabola.

Give students Quiz on section 7.5 – 7.6 Give student the Nature of Roots in Relation to the graph, explaining that the discriminant also can tell what type of graph the parabola will be. If two real roots, the parabola crosses the x axis. If there is one double root then it crosses the x axis at the max or min point (the vertex). If the roots are imaginary, then the parabola does not cross the x axis. Begin by asking students the process of thinking for factoring a quadratic equation. Student should say that they think about factors of the last term, and how those factors sum together to get the middle term. If they don’t ―get‖ this, then give a sample problem and ask students how they would factor this problem. Eventually they will come up with the ―process‖ of factoring. LEARNING ACTIVITIES PART: PRESENTATION OF INFORMATION AND Tell students that instead of factoring quadratic equations, they would be learning MODELING how to create the equations based off the roots. Show students that r1 and r2 are the roots given to a quadratic equation. Explain that an equation can begin by writing, (x - r1)(x - r2) = 0. By multiplying the two binomials together, the equation becomes, . A is only used when the sum or product is a fractional number and not an integer. A is used to make the equation have integral coefficients. Ex: roots are -3 and 1. The sum of these roots is -2; the product of the roots is -3. So the equation to be x2 – 2x – 3 = 0. After showing this example, allow students to work on #11-14 from page 342 from Oral Exercises, and then allow them to share with a partner their answers. Then call on students to tell what answer they had, and allow students to work their answers on the board. __________________________________________________________________ Begin word problems from this section if time allows. Explain to students that once they’ve set up the quadratic equations, that the main goal is to find the min and max. Student should remember that the min and max comes from the vertex (h, k). Students will have to find h, to solve for k, and k will be the min or max of the problem. Work the even problems from the book, page 343 -344.

GUIDED PRACTICE INDEPENDENT PRACTICE CLOSURE Classwork – Page 354 Oral Exercise All Tell class that you hope they did well on the test, and that we’ll be beginning chapter 8 on Variation and Polynomial Equations the next class period.-- Section IV: Analysis of Student Learning The post-assessment is in two parts. The post-assessment was going to be the chapter 7 test, however, while students were taking the tests, students keep complaining about how hard the test was, and constantly asked questions during the test. I knew that we had a great review, and that student were asking great questions, and were giving great feedback during class. However, when the test came, the students acted like they’d never seen any of the information, and thus, I decided to give the students the same pre-assessment, as another part to the post-assessment to see if the students had any growth from the beginning of the unit to the end of the unit. Again, the post-assessment used had a total of 14 points, one point for each correct answer. Number of Students per score Post-Assessment Scores for Entire Class 5 4 3 2 1 0 0 0.5 1 1.5 2 3 4 5 Pre-Assessment 6 7 8 9 10 11 12 13 14 Post-Assessment The graph depicted above shows the Pre- and Post-Assessment scores for the entire class. The purple bars are the pre-assessment, and the red bars are the post assessment. From the graph, one can conclude that after the unit was taught, students scored high on the post assessment. The pre-assessment’s lowest score was 0 points, while the lowest score on the post-assessment was 6 points. The highest score on the pre-assessment was a 6 while the highest score on the post-assessment was the max points, 14. The mean of the pre-assessment was about 2.1 while the mean of the post assessment was 10.8. I think this shows that the students learned a lot from this unit. As I taught the lessons, I would remind students about the questions that were on the pre-assessment and then told them that what was being covered at the moment to help them make the connections from the questions asked before the teaching and why it was asked. The conclusion I can draw from this is that the students improved their preassessment scores as post-assessment scores after the unit was taught. Number of Students per score Post-Assessment Scores by Gender 5 4 3 2 1 0 6 7 8 9 10 Girls Boys 11 12 13 14 This graph shows a comparison between boys and girls in the class. There were 9 girls who completed the post assessment. There were 10 boys who completed the post assessment. From the girls’ data, it appears that they scored slightly higher on the post-assessment than the boys. The girls’ mean score was 11.6, while the boys mean score was 10.1. The median score for the girls was 12, while the median score for the boys 10.5. I think that there were a few factors that contributed to the girls having high scores. The girls in the class seem to be more conscientious about their math work. All the girls sit in the front of the room (by choice), while all the boys sit in the back (by choice). When teaching, the girls are answering more questions when the questions are asked without picking someone. The boys on the other hand, are more talkative, and play around in class more than the girls. While teaching, I constantly have to calm the boys down, not that I don’t with the girls, but more often than not, I’m asking a male student to pay attention. There are a few exceptions. One of the male students is very conscientious about his work, and makes some of the highest grades in the class. The other boys in the class are conscience of their math work; however, they seem to take math class a fun time sometimes. When students were asked to work in groups, or pairs, the girls were more diligent with making sure they got their work done, and would ask me if they were coming up with correct answers. Girls were also more willing to volunteer to go to the board, than boys. The boys were often reluctant about being asked any questions in class in which they had to answer aloud, because they were unsure of their answers then the girls. Many studies have shown that around the age of these students, girls are more likely to score poorly in their math classes and not participate as actively as their male counterparts. However, in this class it seems to be the opposite effect. I do think that the boys learned from the unit, however, I think that they could have performed better on the post-assessment. Many of the students said that they wished they could have had the post-assessment as their unit test because it was easier than test. With the students making a comment like that, I think that they did learn something from the unit, and felt better about answering the questions than they had the first time. Post-Assessment Scores for Two Individual Students Student's Score on Post Assessment 14 12 10 8 6 4 2 0 "Elizabeth"-Repeater "Matthew" - 1st Time The data above compares two students: one, “Elizabeth”, who has taken Algebra II Honors for the second time, and another, “Matthew”, who is taking Algebra II Honors for the first time. “Elizabeth” is repeating Algebra II Honors after taking Algebra II MEGSSS last year with a final score of 70. According to the data, Elizabeth and Matthew scored the same score of a 14 on the post assessment. Elizabeth has shown improvement from her pre-assessment score to her post-assessment score. Elizabeth scored a 4 on the pre-assessment, even after having seen the material before. Her post-assessment score was a 14. This shows that she has learned the concepts that were on the preassessment as I was teaching them. Matthew also showed great improvement from his pre-assessment score to his post-assessment score. His pre-assessment score was a 0, while his post-assessment score was a 14. This shows that Matthew also learned the concepts of the pre-assessment so that he could correctly answer the same questions on the post-assessment. I think this shows that Elizabeth is at the same level up to the same level as one of the honor students, since she scored just as well as the honors student, and maybe they are at about the same level of learning. Distribution of Grades On Unit Test 0% 9% 5% 10% 76% 100-93 (A) 92-85 (B) 84-77 ( C) 76-70 (D) 60 & Below (F) The data above shows the distribution of grades for the unit test. According to the data, the students did not do well on the test. No student made an A. Two students made a B (both 86), one student made a C (81.5), two students made scored a D (75 & 70.5) and the rest, 16 students, scored 60 and below (68 to 18). It looks like the students didn’t learn much during this unit. Only 24% of the students passed the test and 76% of students failed the test. I was extremely disappointed in their test grades. The average score was a 55, while the median was a 55 as well. The highest score was an 86 and the lowest score was an 18. I do think the students learned a lot during the unit. I think the students began to become overwhelmed while taking the test. I also think that the comments by the students during the test caused other students to become unfocused. A few students commented that the test was too hard and this gave others the opportunity to say the same thing and complain. It also didn’t help that my other Algebra II Honors class told some of the students that the test was hard, so therefore, many of them came in thinking that they could not do the test, or that the test was too hard. During the review of the test, I knew that the students knew the material, so I’m not sure why students did not do better on the test than they did. One of the students that scored the highest, usually scores the highest on all test anyway. The other student who scored the 86 was a student who frequently came in after school to get help. Number of Students in each grade catergory Distribution of Grades On Unit Test by Gender 10 9 8 7 6 5 4 3 2 1 0 100-93 (A) 92-85 (B) 84-77 ( C) Boys 76-70 (D) 60 & Below (F) Girls The data above depicts the tests scores made between the boys and the girls. The boys’ averages test score was 48.1, while the girls’ average test score was a 64. However, I think this slightly screwed because there are more boys than there are girls, even though by the graph, it looks like the boys did better than the girls. Since there were more boys, it also would mean that there is a greater chance of boys not doing well on the test than there is girls. I also think that the average is hurting the boys’ score because the lowest score in the class, and 18 was made by a boy. Two boys made the highest scores, of an 86. The girls’ lowest score was a 52, while their highest score was an 81.5. I’m not sure if there is a correlation between why the boys might have done worse than the girls. The only thing I can think of is that boys, with the exception of the one who scored one of the highest scores in the class, isn’t as serious in class as the girls, even though they have their moments as well. I think that out of this class more girls came in after school to receive help when they needed it, with the exception of the other boy that scored the highest score. When it all said and done, I just think that the overall grades were poor regardless of what gender scored better than the other. Score on Unit Test Unit Test Score of Two Individuals 78 77 76 75 74 73 72 71 70 69 68 67 66 65 64 "Matthew" - 1st Time "Elizabeth" - Repeater The data above shows the test score of two individual students, one student “Elizabeth”, who is a repeater, and one student, “Matthew”, who is taking this course for the first time. This data shows that Matthew scored better on the test than Elizabeth. I think this has to do with the fact that Elizabeth did not complete three homework assignments while Matthew completed all his homework assignments. Even though Elizabeth as has seen the material before, she probably still need to do her homework to make sure that she understood the concepts of the unit. However, at the same time, Matthew only scored seven points higher than Elizabeth, but those seven points made Matthew have passing grade. I also do not think that neither Matthew nor Elizabeth put forth their best effort. I’m not entirely sure if there is any correlation between the two scores. Maybe having seen this same information in another course did not make it easier for Elizabeth to pass this test, even though it would stand to reason that she should have scored higher than she did. Grades Grades for this unit were determined by quiz grades, homework grades, and the unit test. Homework was given after every lesson, and if a student failed to do his or her homework, ten percent was taken from their homework score. Test were 60% of students’ grades, quizzes 20%, and homework 20%. Homework was assessed on whether or not the students attempted to complete the assignment. Test and quizzes were graded on accuracy. Quizzes were out of 100 points. Section V: Reflection and Self-Assessment Based off the results in the previous section, it looks like my students did not meet all of the goals I set forth for them to learn. Seventy-six percent of the class failed the unit test, even though the 15 out of the 19 (about 78%) students who took the postassessment passed (same from pre-assessment), while the whole class failed the preassessment. I do think that my students learned something from the unit, clearly shown from the post-assessment results, but I think this only because the post-assessment questions had limited about of actual computational math. Most of the questions required that the students answered a question based of what they thought, while the unit test asked students to answer math question computationally. However, there were a few questions from the pre-assessment that were worded slightly differently on the unit test that most of the students answered correctly. Overall, the results from this unit are very disappointing. If I reflect on their performance and base it off my own performance, I’d have to say that it looks like I did not teach this unit very well. However, my coaching teacher as well as others who observed me during this unit commented on how well I explained information and that they thought my teaching of the unit was great. But because of the how unsuccessful the students were, I equate that to me not having taught the unit well. I feel that I have let the students down. There are many things I would like to and would have done differently if I were given the opportunity to teach this unit again. Because I am in someone else’s classroom, and am following their rules and guidelines, I was unable to do some of the things I wanted to do. I think that this unit was more teacher lead that necessary. I would have liked to have had more student-led learning because I think students are able to better understand and retain information when they discover for themselves what they are learning. The section on graphing quadratics, I would have liked to have incorporated technology, such as the graphing calculator, or Geometer’s Sketchpad. However, my coaching teacher thought it was unnecessary, and a waste of time. Many of my students were in class while I was teaching that section trying to figure out how to graph it on the calculator to see if they could make connections with it. After all, the students are allowed to use their calculators on assessments in class. I thought this would have been a great tool for them to use. I do want the students to understand how to calculator and graph equations with paper and pencil, but I also think that it’s important for them to learn the how to use the calculator proficiently to find their answers. Maybe as part of the assessment, I could have had the student to calculate and graph one equation with paper and pencil, and then allow the students to also graph one by using their calculator. That way the students would be using the knowledge of how to use a graphing calculator, and at the same time, I can assess whether or not the students really understand the concepts. Another thing I would have done differently with this unit was changing the pace. I think the unit was taught to quickly, but this is the way my coaching teacher wanted it. This is the first time that these students have ever seen quadratics, and they need to understand how to solve quadratics by completing the square or using the quadratic formula. Completing the square is not an easy concept to learn, and I think that I should have broken the first section with completing the square, the quadratic formula and the discriminant into two different sections, allowing one whole class period for completing the square and one whole class period of the quadratic formula and the discriminant. There were also two sections of word problems in this unit, and these students do not have a strong background with word problems. I think that spending a day each for the sections that had word problems would have been better than learning the concepts of the section along with the word problems. That would allow the students to be able to decipher and analyze each word problem and connect it to the main idea of the section. I also probably would have done more assessing. Even though I asked a lot of questions and had students demonstrate what they knew on the board, I think I should have done more. I think quizzes are good, but I should have done more assessing if I were allowed to. I also included a lesson plan on a review period, however, was not allowed to use it, because again, it reviewing before a test is a waste of class time. I think that that would have helped me gauge better where the students were in their knowledge of the unit before the test. During the test, many of the students commented that the test was too hard. I don’t think it was too hard, my coaching teacher didn’t think it was too difficult, and the math department head did not think it was too hard. In fact, both my coaching teacher and the department head said that it was not an “honors” test, and was not a test that would challenge the students to a high level. Question 5 of the test was the only question that I put on the test that was “easy” points because I knew that the students would know how a, h, and k affected the position of a quadratic equation. All other questions were asked in class, as well as on the review sheet, just with different numbers. Two questions on the test were questions that the students had seen on a previous quiz, or on the review sheet. As for the review sheet, that was an optional assignment for the students. My coaching teacher believes it is up to the student to want to do the work, and therefore should do the work. If they have any questions, they needed to come before school or after school to get help, but the review sheet was not discussed in class as a whole group. That is one thing I would have changed. I probably would have allowed about 30 to 45 minutes in class for students to ask questions about the review sheet so that they were not just waiting on the answers of the review sheet that was posted online. That way I would be able to go over some of the concepts that were unclear that to the students. Even if only one student needed help with a concept, it probably means that there is another student in the class that has the same question. I also think that the students’ extracurricular activities also affected the students’ performance during this unit. Many students were a part of the Hairspray production, and my of the students I think did not have the time to study like the normally would. Some of the students I think just did not put for the effort needed to perform well. It was also during advisement time, and some students were missing key instructional time while they were in guidance signing up for classes for the next school year. The student that scored the lowest, an 18, actually had advisement in the middle of the test. I told him that his test was just as important and to try to get as much work done on it as possible, but he was too excited about going to advisement, that he never came back to finish is test. I did allow the class another twenty minutes on the test during the next class period since so many students had not finished the test the first time. I enjoyed teaching this unit, however, I’m disappointed that the students did not do as well on the unit test that I would have liked or what I had hoped for. Next time I teach this unit, I’ll keep in mind the changes I’d like to make to this unit, and hopefully, the next group of students produces better results.
