Beginning with a reference to living in a time of both uncertainty and opportunity, this article presents a discussion of key areas where shared understanding is needed if we are to successfully realize the design and use of high quality, valid assessments of science. The key areas discussed are: (1) assessment purpose and use, (2) the nature of…

Most people visit a science center in order to satisfy specific leisure-related needs; needs which may or may not actually include science learning. Falk proposed that an individual's identity-related motivations provide a useful lens through which to understand adult free-choice science learning in leisure settings. Over a 3-year period the…

Examines, in some detail, the process of evaluation and describes methods that have been used in evaluation applied to precollege education. (PEB)

Naturalistic and experimental inquiry methods in educational research and evaluation are described and compared, using illustrations from two science education research projects. Several strengths and limitations of each inquiry style are identified. Suggests that investigators consider both paradigms in planning research and evaluation studies.…

Explains the results and findings of the Cognitive Analysis Project (CAP) which was used to evaluate the intellectual development of children from grades 10, 11, and 12 by analyzing the use subjects made of written language in solving problems and explaining phenomena. (HM)

Discusses methodological concerns raised by Kesidou and Roseman (2002) regarding textbook evaluations and the training of rating teams. (Contains 16 references.) (Author/YDS)

Responds to the comments of Holliday on the analysis of middle school science textbooks with regard to the methods used in the evaluation of curriculum materials. (Contains 22 references.) (Author/YDS)

Criticizes weaknesses in the Gagne research model for checking the validity of learning hierarchies, and proposes a new model which is designed to overcome these weaknesses. (JR)

Some early results are reported of a study to examine trends of student evaluations in college level physics courses. Higher ratings were consistently given for higher level courses. (PS)

Describes the rationale, construction, administration, and analysis of an externally set examination for BSCS students at the end of the twelfth grade. Three areas covered in the examination were: functional information, identification and application of principles, and contributory mode understanding of the principles of biological enquiry.…

The paper documents experiments designed to compare essay and multiple-choice tests as means of testing science learning. Results indicate it is easier to score high on multiple-choice tests; some students substitute quantity on essay tests; and essay tests reveal weaknesses hidden by multiple-choice tests. (RE)

This project consisted of a meta-analysis of U.S. research published from 1980 to 2004 on the effect of specific science teaching strategies on student achievement. The six phases of the project included study acquisition, study coding, determination of intercoder objectivity, establishing criteria for inclusion of studies, computation of effect…

Summarizes major findings of the Harvard Project Physics research and evaluation activity, including data gathering techniques, descriptions of teacher characteristics, information about student responses and learning environments, and final evaluation year results. Indicates that the evaluation program is characterized by considerable research on…

Describes a study that examines the extent to which differences exist in the concept maps of advanced college biology majors (n=25) and beginning nonmajors (n=25) in the domain of mammals. Results indicate that the concept maps of biology majors are structurally more complex than those of nonmajors. (ZWH)

Examines the feasibility of using a time-series design intensively in a school situation. Investigates student attitudes toward a biology class using the operant single-subject design. Despite the developmental nature of this study, it demonstrates that the five-item semantic differential is a valid and easily used instrument. (Author/MA)
