Successful reform of science education requires careful orchestration of a number of factors including technological developments, organizational issues, teacher preparation and enhancement, and advances in the scientific disciplines themselves. Exemplary innovations in exam practices that assess scientific understanding in new and more…

Describes a study which explored some difficulties related to technical and nontechnical vocabulary and the structure of the examination questions in electrochemistry. Includes results from a sample of 1,500 students in the fourth forms. (DS)

A simple curriculum is provided that is designed to allow any school to prepare its students for the Enhanced American College Testing Program Tests (Enhanced ACT). Components of this manual include: (1) introduce the test structure; (2) give the strategy lectures; (3) provide as much structured practice as possible; (4) administer a mock test…

In assessing the quality of science teaching for an effort such as the National Assessment of Educational Progress (NAEP), it is important to understand what is meant by scientific thinking--the search for explanations. Instruction should involve higher-order cognitive skill development, but it is difficult to measure reasoning and understanding…

Figural response items (FRIs) in science were administered to 347 fourth graders, 365 eighth graders, and 322 twelfth graders. Item and test statistics from parallel FRIs and multiple-choice questions illustrate FRIs' more difficult and more discriminating nature. Relevance of guessing to FRIs and diagnostic value of the item type are highlighted.…
