Learning about technology: Family vs. peer pairings

Recently a number of institutions have begun sponsoring nondeficit science and/or technology learning experiences for parents and their middle school-aged children which are intended to be enriching rather than remedial or compensatory in purpose. Very little research documenting the effects of parental involvement in the education of older children has been reported, however. The intent of this article was to present two studies designed to determine whether middle school-aged children's attitudes and content achievement are different when they take a technology course with their parents (parent-child treatment) or with their peers (child-child treatment). The first study focused on learning about communications technology (primarily telegraphs, telephones and radios); the second study focused on microcomputers. Results indicate that parents have little affect in helping their children learn the subject matter of technology courses. Likewise, parents do not affect children's attitudes toward computers. Both results were attenuated by the fact that the students in the studies were high achievers who were interested in and motivated to learn the subject matter, regardless of treatment. Significant differences were noted for computer literacy favoring the parent-child group, however. Parents also seemed to effect children's attitudes toward the subject matter of the courses. Further research needs to be done with less appealing course content or with less motivated students to fully determine the effect of parent-child and child groupings in science and technology courses.     

College choice in the church-affiliated sector of higher education: The influence of congregational cultural orientation

The relationship between a Midwest church-affiliated institution and its supporting congregations provides an opportunity to investigate part of the sociological environment within which a college-choice decision is made for students of a strong denominational orientation. Applying the local-cosmopolitan dichotomy used by previous researchers, this study hypothesized that the cultural orientation of local congregational leaders reflects norms that are aligned to congregational enrollment support or nonsupport for the denominational university. The findings demonstrate that the concepts of cultural, social, and ecclesiological localism-cosmopolitanism are helpful in explaining an individual's support for the denominational university. Also, differing cultural orientations among congregational leaders are related to the degree to which the congregation supports the university with the enrollment of youth.     

Developing a Research Agenda in Science Education

The Science Summit reinforced a question upon which many of us in science education are focused: How can we, the science education community of researchers, practitioners, and consumers, lead policy? We include a brief review of the No Child Left Behind Act and its implications for teachers, and elaborate about one ongoing and growing effort to answer the concerns about the paucity of research expressed at the Summit. We describe a unique and growing collaboration across professional science education and science organizations and societies that focuses on the development of a research agenda. The term ‘consilience’ refers to the “jumping together of knowledge” that leads to scientific advancements, progressive, creative, fluid scientific research and intellectual capacity to move a research community toward an enlightened research agenda. A coherent research agenda enables us to specify what we know, what we need to know, and how research can be employed for creating and implementing policy. The use of a dynamic organizer (such as Pasteur’s Quadrant) for a research matrix of topics provides a possible structure for organizing and cataloging research questions, designs, findings from past studies, needed areas for research, and policy implications. Through this unique collaboration, the science education community can better focus on needs and priorities and ensure that teachers, policy makers, scientists, and researchers in education at local through national levels have an important stake in research priorities and actions.     

A content analysis of research published in the Journal of Research in Science Teaching from 1985 through 1989

To determine if actual practice was consistent with commonly recommended research methods and procedures, this study examined 130 studies reported over a 5-year period in three volumes of the Journal of Research in Science Teaching (JRST). The results were consistent with similar previous analyses (Shaver & Norton, 1980a, 1980b; Wallen & Fraenkel, 1988a) and indicate that appropriate generalizations beyond the confines of the reported studies may be impossible for most (64%) of the JRST studies surveyed. The findings also show that replication studies, which could be employed to offset deficiencies in generalizability, were not commonly encountered (3%) in these 130 reports. In addition, the study results indicate that many researchers (48%) do not properly restrict their conclusions based on the limits imposed by the accessible populations and samples used; nor do they typically provide possible alternative explanations for the outcomes obtained (76%). These findings prompt the following recommendations: 1. A greater awareness and use of replication as a check on generalizability should be encouraged by the science education community. 2. Clearly defined populations (target and accessible) and fully described samples warrant increased attention as report components from authors, reviewers, and editorial board members of JRST. 3. In light of the difficulties inherent in effecting random selection in educational settings, a greater emphasis should be placed on recognizing the limits that the underlying assumptions of inferential statistics place on research conclusions. The results of this study indicate that the methodological quality of published science education research should remain a concern for both practitioners and readers.     

Effects on children's achievement and curiosity of variations in learner control over an interactive video lesson

The purpose of this study was to evaluate the effectiveness of variations in learner control on children's level of curiosity and learning from computer-based interactive video (CBIV). The content was presented as a videodisc visit to an art museum and contained both facts and concepts. A posttest-only control group design was employed with 101 first-and second-grade subjects randomly assigned to one of three experimental conditions—Program Control, Learner Control, Learner Control with Advisement—or a control group. The dependent variables were achievement and three measures of curiosity. Children in the Learner Control with Advisement group scored significantly higher on the achievement posttest than the Learner Control subjects or control group. No differences were found between the Program Control and either of the Learner Control groups. For the curiosity measures, the Learner Control with Advisement subjects scored significantly higher than the control group on Content Exploration, and the subjects in the control group scored significantly higher than those in the Program Control group on Persistence.
