A study is presented which utilizes a selective attention model to investigate the learning effects of different questioning strategies under four experimental conditions using a non-prose medium (science textbook chart) containing information of varying established difficulty. A 14-row, 4-column chart describing 14 vitamins was used to present…

A study was designed to evaluate whether congruency or incongruency between a teacher's intended discovery/inquiry laboratory instructional strategy and his/her actual behaviors used to implement that strategy had an effect on higher level learning by students. Also assessed was whether student performance on science projects can be an effective…

Intended to encourage elementary teachers to explore coastal ecology with their students, this guide presents background material, activity suggestions, and recommended resource materials that could be used in designing a week-long unit on Coastal Awareness. Discussed is how various physical processes such as waves, tides, and currents affect…

This paper describes an analytical solution to a common problem in aptitude-treatment interaction (ATI). The researcher is often interested in the comparison between treatments for a large set of attributes. If this set is large, the chance of non-orthogonality is correspondingly large. In these circumstances the analysis and interpretation…

This study investigated the appropriateness both to the delivery system and to students of Athabasca University of the audiotutorial method of instruction in an introductory level Biology course, which used selections of audiotutorial materials from "Minicourses in Biology."

The Hawaii Marine Science Studies (HMSS) Project has developed over twenty instructional units, which include student laboratory and field investigations, teacher guides and supplementary reference materials. HMSS units can be taught as a one or two semester course in high school marine science, or selected portions can be combined as marine…

Designed for junior high school students, this curriculum on marine science careers contains instructional materials on oceanography and related careers suitable for individualized study. The curriculum is organized into a study-direction book (see CE 020 395) and a separate answer-response book (included in this document). The answer-response…

A new approach to item analysis, concerned not only with differences among individuals, but also differences among the groups in which the individuals may have membership, is described. This multi-level aspect may be applied to studies of differences among individuals, classes, and schools, depending upon the kind of problem being studied and the…

This study attempted to measure the functional availability of knowledge and skills acquired in high school biology as they affect the achievement of students in a first year university course. The study, referred to as retrospective curriculum evaluation, uses a self-assessment instrument, the Knowledge and Prior Study Inventory (KPSI). An…
