An Approach to the Development and Assessment of Instruction in Science at Second Grade Level: The Concept of Energy.
McClelland, John Andrew Gerald
Reported is a study which formed part of the development of a conceptually oriented curriculum in elementary science. A new approach to the introduction of concepts of energy was presented at the second grade level (three second-grade classrooms). A sequence of five lessons, in audiotutorial format, covering energy concepts selected, were developed, trial-tested, revised and then presented at weekly intervals. Tests were developed to assess meaningful learning. Two picture tests were administered to the entire sample, one week apart, following the end of instruction. The first was readministered four weeks later. One group, randomly selected, had six individual interviews (approximately 15 minutes long). Two interviews were non-science to establish rapport. The next two were given following the two picture tests respectively. Scores on the tests were adjusted according to the ability of the student to justify a previous response. The final two interviews concerned new pictures and materials. Exactly half of the interview group showed satisfactory generalizability of all the basic forms of energy. Ten percent showed a satisfactory concept of energy as an entity. None showed a satisfactory concept of energy conservation. Scores corrected through interview were almost all higher than raw scores on the picture tests which suggested that these tests underestimated achievement. Test-retest reliability was 0.75.
