ORES - Objective Referenced Evaluation in Science.
Science process skills considered important in making decisions and solving problems include: observing, classifying, measuring, using numbers, using space/time relationships, communicating, predicting, inferring, manipulating variables, making operational definitions, forming hypotheses, interpreting data, and experimenting. This 60-item test, developed for grade 6 but appropriate for grades 7 and 8, contains several items based on each of these processes. Test characteristics reported include a 5.5 readability level based on Dale-Chall readability formula and assumption of student familiarity with the metric system, content validity, and a split-half reliability coefficient of 0.294 using the Kuder-Richardson 20 formula. Suggested uses of the instrument include: (1) evaluating the level of competency or attainment of students on various processes; (2) evaluating the effectiveness of a particular teaching strategy in relation to process skill attainment; (3) evaluating the effectiveness of a science program or materials in the area of science processes; and (4) using the test as a model for designing an instrument better suited for a specific situation. A list of specific objectives and correct answers corresponding to each item is provided. (SK)
