Describes a nine-week interdisciplinary study of the environment for middle school students, based on the computer simulation "Decisions, Decisions: The Environment," which involves group work, independent work, and a lot of writing. (SR)

Reports on a study of the effects of computer-simulated experiments (CSE), problem solving, and conventional approaches on high school students' chemistry achievement, science process skills, and attitudes toward chemistry. Testing indicated CSE and problem solving produced greater achievement in chemistry and science process skills. CSE produced…

Discussion of computer simulations used for exploratory learning focuses on the design of a hypothesis scratchpad that students can use for hypothesis generation and testing. An experiment with college chemistry students that compared three versions of the scratchpad is described, and the effect of the scratchpads on learning environments is…

Investigates the difficulties that college students (n=83) have in reading and comprehending physics texts. Students were taught the skill of formulating clear questions on textual material. The strategy stimulated students' awareness of the difficulties in reading comprehension and could be used by students as a self-monitoring technique to…

Reports on findings from an interpretive team study of the teaching/learning environments in the science program at an innovative Australian high school, in which 778 students perform laboratory and classroom activities within a self-paced, independent framework. Suggests that the knowledge that teachers require to undertake effective science…

Calculates an approximation to Avagadro's number for one mole of water by assuming the mole to be in cubical form and then halving the cube three times, thereby doubling the surface area of the original cube. The calculations are derived from the work necessary to perform these divisions. Presents calculated values for several liquids. (MDH)

At a middle school in suburban Pittsburgh, Pennsylvania, administrators and teachers used the cognitive domain of the National Association of Secondary School Principals' Learning Style Profile to design "products" that helped compensate for underachieving sixth and seventh graders' skill deficits in mathematics and science. Success…

Presents a study to evaluate the cognitive level of questions in middle school science textbooks. Questions and their location were coded from six randomly selected chapters in eight middle school science textbooks. Results indicated that input level questions were the dominant question type, probably leading to students functioning at lower…

Indicates that measures of reflective reasoning skill are significantly related to initial scientific beliefs about evolution, as well as to gains in declarative knowledge about evolution; however, the same measures are not significantly related to changes in those beliefs. Interrelationships among the study's major variables and their educational…

Presents the case study of a second-year middle school science teacher's beliefs about science and science teaching, and the influence of these beliefs upon classroom instruction. Discusses the teacher's struggle to reconcile conflicting beliefs affecting strategies and outcomes, and the conflict between classroom needs and roles resulting from…

Sixteen students with learning disabilities in junior high special education classrooms were given instruction in science, with levels of teacher enthusiasm manipulated. Results suggest that more enthusiastic presentations resulted in significantly higher academic achievement and lower levels of off-task behavior. (Author/JDD)

Compares current science education reform efforts with those of the 1960s to enhance student learning. Discusses how an "alternative models" view of scientific explanation can contribute to reforms of course goals, social aspects of science learning, instructional practices, and roles for technology. Contains 50 references. (ZWH)

The article presents a Native American tale about the moon that teachers can use to open the door to scientific exploration. After discussing facts about the moon, the article offers a reproducible Navajo story and several follow-up hands-on activities designed to pique students' interest. (SM)

Describes a study of high school students that investigated students' responses to an anomaly generated by the juxtaposition of opposing explanatory frameworks and examined the nature and impact of cognitive conflict as students moved from prescientific to scientific explanatory frameworks concerning the concept of force. (19 references)…

Explains how Richard Plass of Stuyvesant High School has managed to produce more Westinghouse semifinalists than any other teacher in the United States. It describes how the love of teaching coupled with the love of working with children can heighten educational quality. (GLR)
