High School Chemistry TestThe spring 2007 high school MCAS Chemistry test was based on learning standards in the Chemistry content strand of the Massachusetts Science and Technology/Engineering Curriculum Framework (2006). These learning standards appear on pages 69–73 of the Framework.

The Science and Technology/Engineering Curriculum Framework is available on the Department Web site at www.doe.mass.edu/frameworks/current.html.

In Test Item Analysis Reports and on the Subject Area Subscore pages of the MCAS School Reports and District Reports, Chemistry test results are reported under the following four MCAS reporting categories:

■ Atomic Structure and Periodicity

■ Bonding and Reactions

■ Properties of Matter and Thermochemistry

■ Solutions, Equilibrium, and Acid-Base Theory

Test Sessions

The MCAS high school Chemistry test included two separate test sessions, which were administered on consecutive days. Each session included multiple-choice and open-response questions.

Reference Materials and Tools

Each student taking the high school Chemistry test was provided with a Chemistry Formula and Constants Sheet/Periodic Table of the Elements. Copies of both sides of this formula sheet follow the final question in this chapter.

Each student also had sole access to a calculator with at least four functions and a square-root key.

The use of bilingual word-to-word dictionaries was allowed for current and former limited English proficient students only, during both Chemistry test sessions. No other reference tools or materials were allowed.

Cross-Reference Information

The table at the conclusion of this chapter indicates each item’s reporting category and the Framework learning standard it assesses. The correct answers for multiple-choice questions are also displayed in the table.
