1 XX. Introductory Physics, High School

2 High School Introductory Physics Test The spring 2014 high school Introductory Physics test was based on learning standards in the Introductory Physics content strand of the Massachusetts Science and Technology/Engineering Curriculum Framework (2006). These learning standards appear on pages 7477 of the Framework. The Massachusetts Science and Technology/Engineering Curriculum Framework is available on the Department website at Introductory Physics test results are reported under the following four MCAS reporting categories: Motion and Forces Heat and Heat Transfer Waves and Radiation Electromagnetism 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. Test Sessions The high school Introductory Physics 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 Introductory Physics test was provided with an Introductory Physics Formula Sheet. A copy of this formula sheet follows 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 Introductory Physics test sessions. No other reference tools or materials were allowed. 331
