Total Marks: 20

To develop a test in the area of natural science with a total of 20 marks, including a minimum of 5 gradable items that incorporate at least three different types of test items, follow these steps:

Step 1: Identify the learning objectives or concepts you want to assess.
- For example, you might want to assess knowledge of biology, chemistry, physics, or environmental science.

Step 2: Determine the types of test items you will include.
- Multiple-Choice Questions (MCQs): These questions offer several options, with only one correct answer.
- True or False (T/F): These questions assess the accuracy of statements.
- Short Answer Questions (SAQs): These require written responses within a limited word count.
- Diagram/Graph/Sketch Questions: These may require students to label or interpret scientific diagrams, graphs, or sketches.
- Experimental Design Questions: These assess the ability to design and plan scientific experiments.

Step 3: Design the test items.
- For example, you could create three MCQs, one T/F, and one SAQ item.
- Ensure the questions are clear, concise, and aligned with the learning objectives.
- For MCQs, provide four response options, one being the correct answer.
- For T/F questions, provide a statement and ask if it is true or false.
- For SAQs, provide clear instructions about the depth of response expected.

Step 4: Assign mark values to each question.
- Distribute the marks across the questions based on their difficulty and importance.
- For example, you could assign 4 marks to the MCQs (1 mark each), 5 marks to the T/F question, and 7 marks to the SAQ.

Step 5: Develop an assessment tool (marking guide).
- Create a detailed marking guide to ensure consistency in grading.
- Break down the criteria for awarding marks for each question or question type.
- Provide specific guidelines and expectations for different levels of response quality.
