RELEASED SCIENCE ITEMS

This book contains the released Trends in International Mathematics and Science Study (TIMSS) 2011 grade 4 science assessment items. This is not a complete set of all TIMSS 2011 assessment items because some items are kept confidential so that they may be used in subsequent cycles of TIMSS to measure trends.

How Can This Set of Released Items Be Used?

In Teacher-designed Assessments. The items in this book present different ways of measuring students’ understanding in various content and cognitive domains. A teacher may use these items to create an assessment according to the needs of the class after reviewing the items and selecting items of interest.

For Feedback on Student Understanding. Student responses can be scored according to the scoring information provided in the book. Items that coincide with concepts taught in class allow the teacher to gain feedback on the students’ understanding of assessed concepts. For example, a teacher might decide to examine the incorrect or partially correct responses of the class. The teacher might use the items to identify particular difficulties or misconceptions experienced by individual students, which can serve as the basis for some remedial teaching or focused practice.

To Benchmark Student Performance. The teacher might also compare the percent of students in the class who responded correctly to an item with the percent of students who responded correctly to the same item in other education systems or in the United States.

USER’S GUIDEGrade 4

This book contains TIMSS 2011 released items for grade 4. Each item appears on a single page, on which is provided information about the item’s classification and about international student performance on the item. The items appear in the content domain order, as shown in the index on the next page.

Information about item classification

Take a look at the first item on page 1. Across the top are three boxes which identify the item’s content domain (the subject matter in science that the item assesses), its main topic (the specific topic assessed within that subject matter), and its cognitive domain (the cognitive or thinking process assessed). For this item, the content domain is life science, the main topic is life cycles, reproduction and heredity, and the cognitive domain is applying.

Below the row of boxes and above a boxed-in area of the page is the item label. For this item, it is How tadpoles get in the pond. Below the boxed-in area is the item number, which is more commonly used to identify each item than the item label. Within the boxed-in area is the item as it appeared in student test booklets.

Correct answers are shown beneath each item. The correct answer for multiple-choice items is simply a letter code. For example, in the item S031001 on page 1, the letter code D is the correct answer. The correct answers for write-in or open-ended items are explained in a scoring guide. For example, Manuel’s temperature rise in the Life Science domain (page 10), provides an example

of a scoring guide, indicating the general nature of correct and incorrect responses. In some cases, partial credit may be awarded and these items will provide guidelines for fully correct, partially correct, and incorrect responses. Sample student responses are provided for some of the constructed-response items for each scoring category.

Information about international student performance

In the table along the right-hand side of the page are the percent correct statistics for the item. These consist of statistics on the percentage of students in each education system who could answer the question correctly. The lists of education systems are ordered in terms of this percentage. The international average is included as well.

To the right of some of the percent correct statistics are special symbols that indicate when an education system scored significantly higher or significantly lower than the international average. Thus, on the item How tadpoles get in the pond as an example, an estimated 86 percent of U.S. students could correctly answer this item, a percentage that was measurably higher than the international average, after taking into account the standard of error associated with the percent correct statistic for the United States and for the international average.
