The annotated work samples in Judging Standards support teachers when reporting against the achievement standards; when giving assessment feedback; and when explaining the differences between one student’s achievement and another’s. Judging Standards Reporting against the Achievement Standard Grey highlighting identifies those aspects of the achievement standard addressed in the work sample. Annotations in black text refer to the assessment pointers while those in coloured text highlight additional, specific qualities evident in the work. Work Sample: Year 9 Science Performance associated with Grade A, representing excellent achievement Summary of task: Investigation: How length and diameter affect resistance in metal wires Students selected a topic from a given list to investigate. They researched the topic using sources and completed an investigation planning sheet. Students conducted an experiment, including details of the aim, description of equipment, method to be followed and the results. Students then analysed the results, explained problems that were encountered and wrote a conclusion. This information was presented in a detailed report with a bibliography. Year 9 Science Achievement Standard By the end of Year 9, students explain chemical processes and natural radioactivity in terms of atoms and energy transfers and describe examples of important chemical reactions. They describe models of energy transfer and apply these to explain phenomena. They explain global features and events in terms of geological processes and timescales. They analyse how biological systems function and respond to external changes with reference to interdependencies, energy transfers and flows of matter. They describe social and technological factors that have influenced scientific developments and predict how future applications of science and technology may affect people’s lives. Students design questions that can be investigated using a range of inquiry skills. They design methods that include the control and accurate measurement of variables and systematic collection of data and describe how they considered ethics and safety. They analyse trends in data, identify relationships between variables and reveal inconsistencies in results. They analyse their methods and the quality of their data, and explain specific actions to improve the quality of their evidence. They evaluate others’ methods and explanations from a scientific perspective and use appropriate language and representations when communicating their findings and ideas to specific audiences. Key words: Electrical resistance, Electrical conductivity, Scientific inquiry Student achievement is reported at the end of the semester or year using the letter grades and achievement descriptors. Letter grades and achievement descriptors should not be used to assess individual pieces of work. 2014/6416 [2014/9254] Science: Year 9 Grade A Work Sample 1 Work Sample Annotations Develops a plausible hypothesis by linking the independent and dependent variables. Allocates times for each step in conducting the investigation and writing the report. Designs a fair test by selecting appropriate equipment and method; includes points concerning the purpose and/or required characteristics of the equipment. Identifies the independent and dependent variables. 2014/6416 Science: Year 9 Grade A Work Sample 2 Work Sample Annotations Identifies information to be researched and data to be collected. 2014/6416 Science: Year 9 Grade A Work Sample 3 Work Sample Annotations Provides clear and detailed explanations of complex scientific models. Researches background information to support an explanation of the hypothesis. 2014/6416 Science: Year 9 Grade A Work Sample 4 Work Sample Annotations Supports explanations of the method outlined on the following page with the use of appropriate, clear, labelled photographs. 2014/6416 Science: Year 9 Grade A Work Sample 5 Work Sample Annotations Provides a detailed step-bystep method, including repeat trials or replicates, enhanced by photographs. Supports explanations of these steps with the use of appropriate scientific terminology, e.g. reliable, interval, resistance. Modifies the method based on initial observations or measurements 2014/6416 Science: Year 9 Grade A Work Sample 6 Work Sample Annotations Constructs an appropriate table and records data accurately. Omits units in some column headings. Includes repeat trials or replicates, and excludes outliers, where appropriate, when calculating averages Selects and constructs an appropriate graph type, although the interval is inaccurate in this instance. 2014/6416 Science: Year 9 Grade A Work Sample 7 Work Sample Annotations Constructs an appropriate table and records data accurately. Omits units in some column headings. Includes repeat trials or replicates, but doesn’t exclude outliers when calculating averages. Selects and constructs an appropriate graph type, displaying data accurately. 2014/6416 Science: Year 9 Grade A Work Sample 8 Work Sample Annotations Identifies and uses scientific knowledge to explain patterns and trends in the data. Explains results using correct scientific terminology and knowledge, and suggests future investigations or applications related to content of the investigation. Identifies sources of error in the investigation, explains their impact and makes specific suggestions for improving the accuracy of data. 2014/6416 Science: Year 9 Grade A Work Sample 9 Work Sample Annotations Offers a conclusion, providing a summary of the patterns or trends in the data and making reference back to the original hypothesis. Includes a brief bibliography appropriately formatting sources. 2014/6416 Science: Year 9 Grade A Work Sample 10
