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…

Studying "Caenorhabditis elegans" ("C. elegans") live cultures provides excellent opportunities for authentic inquiry in a high school anatomy and physiology or other biology lab course. Using a digital dissection microscope, a student can photograph the organism during various stages of development and study and analyze the images. In this…

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 paper describes the pedagogical impact of real-world experimental projects undertaken as part of an advanced undergraduate fluid mechanics subject at an Australian university. The projects have been organized to complement traditional lectures and introduce students to the challenges of professional design, physical modelling, data collection…

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…

This paper reviews the literature supporting a discovery- or inquiry-based learning approach to science and describes its benefits for students and teachers. The creation and evaluation of a website related to discovery-based learning is also described. (Contains 20 references.) (WRM)

Describes an activity that integrates biology and physics concepts by experimenting with the seed dispersal of common milkweed or similar wind-dispersed seeds. Student teams collect seeds and measure several parameters, review principles of trajectory motion, perform experiments, and graph data. Students examine the ideas of…
