Investigated differences between middle school and junior high instructional strategies and the effects on adolescent attitude toward science in school and science achievement (n=570) and evaluated variations within grade level, gender, race, general ability, and socioeconomic group. Discusses results in terms of effectively implementing changes…

Describes an extended problem-solving activity utilizing drift-bottles that encourages students to deduce probable and great-circle drift-bottle routes, to use logic based on unit calculations, and to estimate the distance traveled and the minimum velocity of these drift-bottles. Includes materials needed, learning objectives, procedures,…

Describes the importance of estimation in science for planning projects, conducting experiments, and developing theories. Defines order of magnitude. Provides explicit mathematical equations and calculations to estimate answers for seven provocative physics problems. Includes nine additional open-ended problems with hints and solutions. (PR)

Reviews the work of the Commission on Undergraduate Education in the Biological Sciences (CUEBS) from 1964 to 1972. Suggests that now is the appropriate time to reassess their efforts, to build on their successes, and to use their experience to attack some of the continuing problems facing biology education.

Explains how insects can be used to stimulate student writing. Describes how students can create their own systems to classify and differentiate insects. Discusses insect morphology and includes three detailed diagrams. The author provides an extension activity where students hypothesize about the niche of an insect based on its anatomy. (PR)

Reports a study that investigated the relationship among (1) teacher's attitudes and implementation of inservice workshop developed learning cycle science materials, and (2) elementary school student's conservation reasoning and language used to describe properties of objects. Data were gathered from 100 students from grades K-5 and 16 teachers…

Reports a three-year naturalistic study to determine whether collaborative reflection could enhance teaching and learning of science by generating desirable cognitive, metacognitive, and affective outcomes. (PR)

Describes the three components of an enrichment program developed in Port Angeles, Washington, to improve mathematics and science instruction: (1) classroom instructional units conducted by a certified teacher, (2) teacher inservice sessions to develop teacher skills, and (3) Family Learning Nights to encourage parental involvement. Enrichment…

Reports observations of primary teachers (n=14) efforts to provide activity-based lessons for their pupils. Teachers' beliefs that their lessons were student-centered were not confirmed by the observations of the lessons. Discusses implications of the findings for inservice teacher education and parental involvement. (MDH)

Eighth graders' ideas about thermodynamics, and their understanding of thermodynamics principles, were assessed before and after they attended a one-semester course on thermodynamics. Results characterized students' views concerning scientific explanations of phenomena, parsimonious versus descriptive explanations, the application of science…

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…
