High School Chemistry TestThe spring 2012 high school 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 website at www.doe.mass.edu/frameworks/current.html.
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 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 English language learner 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.
