Describes an advanced NMR project that can be done with a 60-MHz continuous-wave proton spectrometer. Points out the main purposes are to give students experience in second-order NMR analysis, the simplification of spectra by raising the frequency, and the effect of non-hydrogen nuclei on proton resonances. (MVL)

Describes a model that teaches a problem-solving process and provides students with the opportunity to practice, develop, and enhance their thinking skills. States that applying learning to real problems is needed to increase a student's thinking ability. Provides diagrams of the problem-solving cycle and levels of thinking. (RT)

Describes a module in which students seek to gain an understanding of factors that interact in the ecological system of their school. Presents sample questions for use in reinforcing concepts and evaluating student learning, directions for four task activities, and topics for some of the remaining task activities. (RT)

Reports on Japanese science education from observations made of one school and one teacher. Compares the school to an American suburban "prep" high school with well-disciplined students. States that the reason students learn is because the Japanese consider education to be extremely important. (RT)

Provides a demonstration for showing the usefulness of thermal principles to physical science students who have difficulty understanding conventional explanations. Outlines materials, procedures, discussion, and advantages of using this method. (RT)

Presents a procedure used in sophomore level organic chemistry which has been particularly useful for organic qualitative analysis. Uses a nine-well spotplate and one-two mg of solid and three-four drops of eight different solvents. Solubility is checked at different temperatures. Provides a solubility table. (MVL)

Describes a Teacher Intervention Program modifying classroom techniques and environments for fostering the participation of girls in high-school science classes. Reports that students who were taught by trained teachers, compared to students who were not, have higher scores on tests of attitudes toward science, perceptions of science, and science…

Learner and program control of content review were provided in science computer-assisted instruction for 98 eighth graders. Results indicate that students given limited control over instruction can adjust their study behaviors appropriately and achieve greater learning in the same amount of time as do students not given such control. (TJH)

This study compared the effects of an advance organizer and a prerequisite knowledge passage on learning and retention measured at low and high levels of the cognitive domain. The advance organizer group performed better on the framework test; the prerequisite knowledge group performed better on prerequisite knowledge test. (Author/YP)

Describes the nature of cognitive research. Misconceptions research in mechanics and electricity are reviewed. Research results on expert/novice differences in knowledge organization and problem solving are reviewed. Implications for classroom teaching are discussed. Lists 34 references. (YP)

Discusses the calculation of free energy in reactions between silicon dioxide and carbon. Describes several computer programs for calculating the free energy minimization and their uses in chemistry classrooms. Lists 16 references. (YP)

Explains science teachers' perceptions and decisions about the development and implementation of a science/technology/society curriculum. Discusses the teacher interviews based on teachers' decisions. Summarizes five themes: concerns over content, discomfort with grouping, uncertainties about evaluation, frustrations about student population, and…

Describes a lesson in which instruction is initiated through the right cerebral hemisphere by using visualizations as concrete aids to learning. Explanations include a hand model which is used to illustrate the dynamics of guard cell activity of stomates and a paper folding model to show increase in surface area. (RT)

Reports that 26 of 199 responding colleges require the Fundamentals of Engineering examination. States that of the 26, 16 require it to be taken college-wide and 3 require the student to pass. It was estimated that fewer than half of all graduating engineering students take the exam. (MVL)

A procedure where homework assignments are collected, graded, and returned each week is suggested. Students were used to grade each other's homework against copies of the solutions according to criteria established at the beginning of the course. Student response has been positive. (MVL)
