Examines relations between the philosophy of science, scientific research methods, and the methods of school science teaching. Discusses a "Standard Philosophy of Science" and a "New Philosophy of Science." Proposes that the epistemological, sociological, and psychological aspects of scientific knowledge are important…

Investigates commonsense knowledge schemes connecting the elements weight, air, and gravity to the phenomena of free fall of a range of students from primary school children to adults. Finds that majority of people from the secondary education level onwards held alternative schemes. Discusses educational impacts of mass media. (Author/YP)

Reports two electrochemical demonstrations. Uses a hydrogen-oxygen fuel cell to power a clock. Includes description of methods and materials. Investigates the "potato clock" used with different fruits. Lists emf and current for various fruit and electrode combinations. (ML)

Examined the extent to which students' alternative conceptions changed as a function of age. Reports that many alternative views remain intact throughout the school years. Provides several suggestions for teaching and research within the context of a neoconstructivist view of learning. (Author/YP)

Examines the influence of both locus of control and three instructional strategies to foster an understanding of the nature of science. Reports that the nature of science was most predictable for a separate process/content/teaching methods and logical thinking ability was the best predictor of the nature of science. (Author/YP)

A software package which can aid descriptive geometry instruction is described. Included are the features of the software and the software configuration. This software has been honored as the best and most advanced software of its kind in the People's Republic of China. (KR)

Students' reactions and performances were examined when taught engineering geometry concepts using a standard microcomputer-aided drafting software package. Two sample groups were compared based on their computer experience. Included are the methodology, data analysis, and conclusions. (KR)

Proposed is a hierarchy of visual learning giving three primary stages of visual learning as well as seven hierarchical stages. A clarification of terms associated with visual learning is presented. (KR)

An explanation of 3-D Computer Aided Design (CAD) usage to teach spatial geometry concepts using nontraditional techniques is presented. The software packages CADKEY and AutoCAD are described as well as their usefulness in solving space geometry problems. (KR)

Action researchers teaching a required preservice physical science course attempted to develop feminist pedagogy for science instruction that reduces female students' apprehension and insecurity about science, tests methods of stimulating greater interest in science, and counteracts the inherent gender-bias in the discipline of science. (38…

Ways in which students are allowed to choose, based on their curiosity at the moment, which way they will move through a lesson are described. Available software for interactive biology programs and available authoring software for developing interactive programs by teachers and students are listed. (KR)

Described is an assignment in which students read and write reviews of four journal articles chosen from preselected biology topics. Suggestions to help achieve maximal effectiveness are included. Directions for grading the review articles are provided. Discussed is how this assignment can help students develop more sophisticated writing skills.…

In introductory physics courses at the Pennsylvania State University, student preparation outside class was inadequate to meet course needs. The plan-do-check-act cycle of the Total Quality Management approach was successfully used in this situation to evaluate instructional changes and help balance increased student assignments with increased…

A new classification of rocks that requires no tools other than a hand lens and that is both comprehensive and informative is described. Each of the three main rock groups is treated in two-dimensional, rectangular charts with additional appended boxes that provide optional mineralogical and textural terms that can be used in rock names. (PR)

Requiring students in one introductory college course on weather/climate to keep logs with articles from popular media was found to produce three types of log topics with three kinds of relationship to course content. The technique helped students think more actively and provided the teacher with new course material. (MSE)
