This study reports on a case study about multimodal work in a primary physics classroom focusing on forces. Previous research reports that students benefit from multimodal work in science classrooms. Yet, few systematic studies have been performed to reveal how students represent their experiences and ideas of science phenomena over time within…

Argument-based interventions in science education have largely been motivated by the perspective that students lack knowledge of argument. Recent studies, however, suggest that contextual factors influence students' argument quality. The authors hypothesize that a key limiting factor lies in students' abilities to recognize when to employ…

Inquiry experiences in secondary science classrooms are heavily weighted toward experimentation. We know, however, that many fields of science (e.g., evolutionary biology, cosmology, and paleontology), while they may utilize experiments, are not justified by experimental methodologies. With the focus on experimentation in schools, these fields of…

The study explores how a complexity approach empowers science learning. A complexity approach represents systems as many interacting entities. The construct of micro-macro compatibility is introduced, the degree of similarity between behaviors at the micro- and macro-levels of the system. Seventh-grade students' learning about gases was studied…

Relations between parental reports of children's interests related to science and opportunities for science learning were examined longitudinally in 192 children between ages 4 and 7 years. Science interests were tracked during 1-year periods (ages 4-5, 5-6, and 6-7) and were more prevalent among boys, particularly prior to age 6 years. Gender…

We describe a study of programs to deepen families' scientific inquiry practices in a science museum setting. The programs incorporated research-based learning principles from formal and informal educational environments. In a randomized experimental design, two versions of the programs, called "inquiry games," were compared to two control…

The laboratory has been given a central and distinctive role in science education, and science educators have suggested that rich benefits in learning accrue from using laboratory activities. Twenty years have been elapsed since we published a frequently cited, critical review of the research on the school science laboratory (Hofstein & Lunetta,…

Uses base-year data from a nationally representative database (NELS:88) to identify important explanatory factors for gender differences in science performance. Documents a large advantage for boys on the subtest of physical science and a modest advantage for girls in life science. Concludes that laboratory experiences are beneficial for girls'…

Describes a study in which participants in a summer institute for secondary science teachers performed a series of experiments with a radio telescope. Concludes that a radio astronomy teaching facility would encourage students to use their own initiative and strategy in working with the scientific concepts involved. (MLH)

This study developed and validated an inventory to measure students' attitudes toward and interest in laboratory work in high school chemistry. Factor analysis provided some evidence that interest in and attitude towards laboratory work in high school chemistry is not unidimensional, as it has been assumed to be. (BT)

Reviews several schemes for organizing science laboratory objectives and activities and for analyzing several techniques designed to measure these laboratory outcomes. The need for further study and analysis of psychomotor behaviors in science education is emphasized. (HM)

Investigated the role of "a priori" ideas in planning experiments and data processing leading to inferences. Thirty-one students (ages 11-13) observed a "combustion/candle in a closed container" experiment and were asked to interpret sets of measurements. Findings, among others, show that children preferentially experiment on…

This study attempted to determine at what grade levels children develop the ability to combine and control variables, the effect of the elementary science program on this development, and the relationship between a child's ability to control variables and his ability to form combinations of variables. (GS)

Evaluates the value and effectiveness of college science laboratory instruction. An observational system called the Science Laboratory Interaction Categories (SLIC) was used to assess the performance of students and instructors in introductory and advanced laboratories of a large midwestern university. (HM)

An instrument for the continuous assessment of high school physics students' laboratory performance was developed and evaluated. Physics teachers (N=25) observed students conducting experiments on film to judge student performance against a standard set of criteria. Results suggest increases in observational objectivity and precision as well as…
