Investigated skills needed for critical reading of physics texts, their separability and hierarchical ranking, and relation to problem solving ability. Reports that skills required to comprehend texts in continuous format and discriminate unreported statements are respectively of higher level than and separable from those required to comprehend a…

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…

Tested Richard Duschl's triadic model of the growth of scientific knowledge against research practices of 10 accomplished life scientists. Reports that the scientists were willing to change their aims, methods, or theories and were both realists and relativists depending on the scientific discourse about the phenomena in question. Discusses…

Collected demographic data, intentions to engage in science, and attitudes of urban, middle school students. Reports results in terms of family variables, students' educational and career plans, internal attributes (self-concept, science anxiety, and achievement motivation), attitude toward science teachers and other students, friends' attitudes…

Interviewed first-grade children (n=40) about forests and living things found in them. Reports that children generally assigned most forest-dwellers to the forests, but also tended to assign almost all other animals, especially carnivores, to the forest as well. Results indicate a general lack of awareness of plant life, insects, water resources,…

Measured children's (n=182) competence at syllogistic reasoning and in solving a series of problems requiring inductive reasoning. Reports that syllogistic reasoning and inductive reasoning were significantly correlated with both simultaneous and successive synthesis. Provides a basis for understanding the roles of spatial and verbal-logical…

Investigated the problems chemistry majors have with learning distillation concepts in traditional chemistry laboratory courses. Reports that students take the generalized concepts at face value, construct decontextualized concepts for distillation, and cannot interpret their observations or make reasoned decisions based on the theoretical…

Investigated gender patterns with respect to entry rate, project topic, and project type in a state-level science competition. Reports that for the past 20 years the participation rate has been greater for girls than for boys. Boys are more likely than girls to prepare physical, earth, math/computer, and experimental research-based projects. (45…

Compared students in a model preservice program to other students taking similar courses on their conceptual understandings of science and mathematics, their investigative proficiencies, and their beliefs about effective methods of teaching. Reports that students in the model program developed more thorough understandings and more reform-minded…

Presents concept mapping as an effective tool for developing an integrated curriculum. Includes examples of concept maps that represent an entire veterinary curriculum, specific courses, and case-based exercises. (21 references) (Author/JRH)

Discusses a study designed to understand 11th-grade students' learning during conversations with their teacher over and about a computer-based Newtonian microworld, Interactive Physics. Illustrates that students' learning was not local but persistent, in that they used appropriate canonical science talk without teacher support. (36 references)…

Presents results of an interactionist analysis of data from a two-year ethnographic study of one high school chemistry classroom. Findings indicate that the teacher's uses of language fell into three related categories: accuracy and precision in science language, distinguishing between science and other disciplines, and personal pronouns to…

Employed an interpretive methodology to examine interrelations between teacher and student actions in a context of teaching and learning in a grade-11 chemistry class. Teacher and student goals, beliefs about teacher and learner roles, and constructions of the context were coherent to such an extent that there was little impetus for change. (24…

Presents a meta-analysis of literature which examined gender differences in students attitudes toward science, and correlations between attitudes toward science and science achievement. Results found that boys show a more positive attitude toward science than girls in all types of science and that a positive attitude results in higher achievement,…

Field tests of the Science Laboratory Environment Inventory (SLEI) with (n=5,447) high school and college students in six countries furnished evidence that science laboratory classes are dominated by closed-ended activities and that females held generally more favorable perceptions than males. Describes the development and validation of SLEI.…
