Describes an integrated science unit to help preservice teachers gain confidence in their abilities to learn and teach science. The teachers role played being salmon as they learned about the salmon's life cycle and the difficulties salmon encounter. The unit introduced the use of investigative activities that begin with questions and end with…

This study sought to develop and verify the Index of Science Reading Awareness (ISRA) based on a model of an efficient, successful interactive-constructive science reader and three independent metacognitive awareness domains. Results did not support the assumption about the three independent metacognitive awareness domains and also indicated that…

Examines perceptions of eighth graders in a science teaching environment in which they guide their own learning, frame problems for inquiry, design data collection procedures, and interpret and present data in a convincing fashion. Asserts that, in constructing their inquiries, students successfully negotiated courses of action and established…

Describes a study by British researchers that attempted to describe progression in learning in terms of a common framework for all students. Elementary school students completed periodic interviews while being taught measurement skills. Results found a wide spread of attainment in measurement in each age range but less clear progression between…

Investigates the dimensions underlying performance on the diagrams, tables, and maps subset of the Swedish Scholastic Aptitude Test. Analyzes data from two test versions by using a structural-equation modeling technique on 14,463 and 19,636 examinees respectively. Concludes that gender difference in performance is due, to a great extent, to the…

Investigated the percentage of high school seniors reporting intentions to major in education and actually majoring in education over 2 years, examining high school academic proficiency levels and the impact of type of college attended (2-year or 4-year). Less than half the students majored in education. There were differences by high school…

Sefton School Advisory Service has been working with Crossens Nursery School in Southport on a project to develop science and technology. The overall project was inspired by the visit of the headteacher to the Reggio Emilia school in Italy. Central to the Reggio approach is a philosophy which values the children as researchers and as partners with…

Because cell biology has rapidly increased in breadth and depth, instructors are challenged not only to provide undergraduate science students with a strong, up-to-date foundation of knowledge, but also to engage them in the scientific process. To these ends, revision of the Cell Biology Lab course at the University of Wisconsin-La Crosse was…

For beginning programmers, inadequate problem solving and planning skills are among the most salient of their weaknesses. In this paper, we test the efficacy of natural language tutoring to teach and scaffold acquisition of these skills. We describe ProPL (Pro-PELL), a dialogue-based intelligent tutoring system that elicits goal decompositions and…

This study summarizes the results of a quantitative synthesis of the retrievable primary research dealing with the effects of new science curricula on student performance. This study synthesizes the results of 105 experimental studies involving more than 45,000 students and utilizes the quantitative synthesis perspective to research integration…

Although substantial literature exists regarding learning with visuals, most consider text the primary channel with varying amounts of visuals explored as a secondary channel. This study considered the effectiveness of visuals-only procedural guides versus visuals plus added text, using visuals as the primary channel and using visuals developed…

This manual specifically addresses teaching middle level students and offers teachers a variety of activities that were selected and edited to reflect middle level philosophy. It is divided into five chapters each with a different focus that contain hands-on activities designed to provide many exciting and fun experiences for adolescents. Every…

This document resulted from a project undertaken to develop a set of program-specific and occupationally relevant performance (learning) objectives for the Ontario Basic Skills/Formation de Base de l'Ontario (OBS/FBO) program. It describes project activities, including a literature review in three related areas: understanding what literacy means,…

Contrary to what many students think, heat flows from hot to cold. Working in groups of 3-4, students investigate the properties of insulators in attempts to keep a cup of water from freezing and, once it is frozen, to keep it from melting. This activity requires a 4.5-hour time period for completion. (Author/SOE)

This document was created to establish competency goals and objectives for teaching and learning science in North Carolina for grades K-12. It contains the concepts and theories, strands, skills, and processes upon which all science instruction should be based. In addition, the curriculum defines and illustrates the connections between the…
