Develop one table of specification of any unit from science curriculum.
Answer: Table of Specializations:
A Table of Specifications is a two-way chart which describes the topics to be covered in a test and the number of items or points which will be associated with each topic. Sometimes the types of items are described as well.
The purpose of a Table of Specifications is to identify the achievement domains being measured and to ensure that a fair and representative sample of questions appear on the test. As it is impossible, in a test, to assess every topic from every aspect, a Table of Specifications allows us to ensure that our test focuses on the most important areas and weights different areas based on their importance / time spent teaching. A Table of Specifications also gives us the proof we need to make sure our test has content validity.
Tables of Specifications are designed based on:
- Course objectives
- Topics covered in class
- Amount of time spent on those topics
- Textbook chapter topics
- Emphasis and space provided in the text
A Table of Specification could be designed in 3 simple steps:
1. Identify the domain that is to be assessed
2. Break the domain into levels (e.g. knowledge, comprehension, application …)
3. Construct the table:
The more detailed a table of specifications is, the easier it is to construct the test The purpose of a Table of Specifications is to identify the achievement domains being measured and to ensure that a fair and representative sample of questions appear on the test. Teachers cannot measure every topic or objective and cannot ask every question they might wish to ask. A Table of Specifications allows the teacher to construct a test which focuses on the key areas and weights those different areas based on their importance. A Table of Specifications provides the teacher with evidence that a test has content validity, that it covers what should be covered.
How can the use of a Table of Specifications benefit your students, including those with special needs?
A Table of Specifications benefits students in two ways. First, it improves the validity of teacher-made tests. Second, it can improve student learning as well.
A Table of Specifications helps to ensure that there is a match between what is taught and what is tested. Classroom assessment should be driven by classroom teaching which itself is driven by course goals and objectives. In the chain below, Tables of Specifications provide the link between teaching and testing.
Objectives Teaching Testing:
Tables of Specifications can help students at all ability levels learn better. By providing the table to students during instruction, students can recognize the main ideas, key skills, and the relationships among concepts more easily. The Table of Specifications can act in the same way as a concept map to analyze content areas. Teachers can even collaborate with students on the construction of the Table of Specifications- what are the main ideas and topics, what emphasis should be placed on each topic, what should be on the test? Open discussion and negotiation of these issues can encourage higher levels of understanding while also modeling good learning and study skills.
Analyze results by level and content area:
If students getting all lower level questions but missing higher level, then you're not doing your job; if all have got answers to one unit but not another, may have to reteach that unit, etc.
