Reports on the testing of two approaches to enhance learning in geological field trips through the use of technology. One approach used an advanced flight simulator and the other used digital cameras and computers. (Contains 18 references.) (DDR)

Details the use of tabletop models that demonstrate concepts in direct current electrical resistivity, self-potential, and electromagnetic geophysical models. Explains how data profiles of the models are obtained. (DDR)

Provides a list of web sites that pertain to rivers that are practical, well organized, and have authentic content. (DDR)

Describes an approach to the teaching of electricity that uses box and AVOW diagrams, novel representations of the properties of the electric circuit that portray current, voltage, resistance, and power. The diagrams were developed as aids in learning, understanding, and problem solving and to promote conceptual change by challenging a number of…

Studied whether children's achievement strategies predict the development of their reading and mathematics skills during the first school year or whether these skills predict changes in their achievement strategies. Findings for 105 Finnish first graders show that maladaptive strategies hamper improvement in reading and mathematics; skills did not…

A study compared the reading fluency, comprehension strategies, and content test scores of 16 students with mild disabilities who participated in a nine-week world history class taught using peer tutoring or teacher-directed guided notes. Students who were participated in peer tutoring significantly outperformed the other students on content-area…

Presents a model for designing student-centered, technology-rich learning environments (SCenTRLE) to help educators operationalize constructivist and student-centered approaches to teaching and learning. Highlights include facilitating knowledge construction and lifelong learning; technology use; student attitudes; levels of implementation;…

Describes the ways in which a problem-based learning (PBL) approach to teaching precalculus can prepare students for calculus by helping students develop a conceptual understanding rather than learning through symbol manipulation and memorization. Discusses the exponential, trigonometric, polynomial, and rational function modules employed. (NB)

Examines the relationship between high school students' perceptions of their science learning environments and their motivation, learning strategies, and achievement. Discusses the focus of shared perceptions and instruction and indicates that shared perceptions focused on understanding and independent thinking positively predicted students'…

Examines the relationships between organic chemistry achievement and a number of cognitive and noncognitive variables, and explores whether gender differences existed for any of these relationships. Concludes that general chemistry grade, ACT-math score, and motivation are significant predictors of organic chemistry achievement. Indicates gender…

Explores challenges of learning to think about data as signal and noise. Examines the signal/noise metaphor in the context of three different statistical processes: (1) repeated measures; (2) measuring individuals; and (3) dichotomous events. Makes several recommendations for research and instruction on the basis of this analysis. (Author/KHR)

Examined the results of at-risk students' participation in a learning strategies tutorial concurrently with enrollment in general biology. Results were mixed, but refinement of the tutorial in a follow-up study showed positive changes in learning behavior and higher final grades than at-risk control group students. (EV)

Defines problem-based learning (PBL) as an instructional method in which problems provide the context for students to develop skills and knowledge. Describes a study that examined whether students perceived that PBL courses were more effective than non-PBL courses at helping them develop specific outcomes. Reports that PBL students' perception of…

Discusses a program to improve library instruction at Rider University (New Jersey) and reports on a pilot assessment. Topics include problems with assessment; student assessment tools; and five standards based on ACRL (Association of College and Research Libraries) standards that were designed to improve teaching methods to address learning…

Describes the cognitive processes required to troubleshoot faults and describes an architecture based on that cognitive model for designing learning environments that engage novices in troubleshooting while supporting their construction of requisite knowledge. This model can be applied to different kinds of troubleshooting problems, enhancing the…
