The test "Measurement About Science and Scientists" (Project Physics, Form 1) was prepared by choosing 101 items from the "Test on Understanding Science" and from the "Science Process Inventory" on the basis of their ability to indicate changes in students' knowledge. The method of building derived tests is described,…

The purpose of this study was to compare a factual method of teaching introductory college astronomy with a conceptual method. Two sections of about 100 students each were taught from the same textbook, but had the same information presented by different techniques and with different emphasis. The control group was taught in a generally factual…

The outcomes of 1333 students enrolled in Chemical Educational Materials Study (CHEMS), Chemical Bond Approach (CBA), and a traditional chemistry course were compared on the basis of grade and ability level. For the total group, students taking CHEMS and CBA performed significantly better on the American Chemical Society Cooperative Examination in…

Investigated was the effect of different types of laboratory reports on measured outcomes of the Chemical Education Materials Study (CHEMS) Chemistry. Compared were procedures using essay laboratory reports, mimeographed laboratory sheets prepared by the investigator and completed by the students, the laboratory manual for the course completed by…

Describes procedures, results, and conclusions of a study designed to evaluate the success achieved in an experimental secondary school course aimed at fostering scientific literacy. The pretest-posttest control group design with matching was used. Results indicated that pretreatment-posttreatment growth score differences between the comparison…

The Personal Beliefs Inventory was used to identify teachers who had strong feelings toward or against the use of experimentation in science classes. Students in the classes of the 16 teachers with the most extreme scores on the Inventory were administered two tests: one class of each teacher was given the Test on Understanding Science and another…

The "Test on Understanding Science, Form W" and the "Nelson Biology Test, Form E", were administered before and after a college general biology course to a random selection of students who had chosen to take an individualized study program and to a random group of students who had chosen to follow the lecture-laboratory…

The purpose of this study was to describe and exemplify a model to aid schools in introducing and evaluating new instructional programs. Four basic steps are identified: selecting the curriculum goals, identifying a possible program or programs, evaluating the implementation of the program or programs, and developing and obtaining instruments for…

Students who solved problems individually or in small informal groups understand science and scientists better than those who solved the same problems (based on BSCS Blue Version) as a class group. (AA)
