Describes the presence of high correlations between pooled scores on two test formats when administered to 170 students in an introductory physics course. Concludes the gradability of machine scorers is comparable to that of manual grading in this repeated-measures design. (CC)

Discusses insightful learning, trace system,'' and laws of perception and Pragnanz in connection with problem solving and critical thinking in science teaching. Suggests 19 guidelines for sequencing curriculum and identifying activities for use in science classes. (CC)

Presents a collection of documents between 1880 and 1971 which is useful in studying broader aspects of the science education history. Bibliography is included. (CC)

Proposes that an examination of the history of the development of science concepts can reveal conceptual difficulties and guide the development of instructional methods where the student is helped to actively organize information so that he is involved in formulating the concept.'' (AL)

There were no differences in the types of responses given by children in response to the question What makes clouds move?'' whether they were interviewed by telephone, by a person in normal dress, or by someone wearing clerical dress. The responses were similar to those reported by Piaget. (AL)

There were no differences in biology achievement or critical thinking scores of students of teachers with different degrees of self actualization. However, when grouped according to their success in increasing students' critical thinking ability, effective teachers could be distinguished from ineffective by their scores on the existentiality''…

Describes the difficulties encountered in selecting material to be included in the reviews of science education research in the Curtis Series'' published by the Columbia Teachers' College Press. Presents evidence outlining the weaknesses of using a jury'' to determine so-called superior research. (AL)

Reports the presence of a facilitating effect of exposure to a pretest on the Watson-Glaser score and a posttest following grade 12 biology instruction. (AL)

Describes the production of a test with a low verbal load for use with elementary school science students. Animated films were used to present appropriate and inappropriate models of the behavior of particles of matter. (AL)

Presents the results of a study of the validity and reliability of a modification of the Reed Science Activity Inventory used with British high-ability students. (AL)

Describes the techniques used to construct the Inventory of Societal Issues,'' and describes the seven scales that constitute the battery. All scales reflect environmental issues related to science and technology. (AL)

Although students who used the Physical Science Study Committee experiments improved in their understanding of the conservation of momentum, greater gains were made by those who used a computer simulation of one dimensional elastic collisions in a vacuum. (AL)

Diagnostic testing followed by remedial work did not facilitate learning in a program on constructing and interpreting graphs, whether administered by the teacher or the student. Reasons for the lack of success are postulated. (AL)
