Junior high students who were at risk of dropping out of school (n=45) were taught using the Cognitive-Based Instructional System (CBIS). Positive cognitive skills change occurred in 38%; there were discrepancies between dropout prediction test results and teacher perceptions of students at risk; CBIS implementation would require a significant…

Investigates the effects of a role-taking, action-learning program on the cognitive and ego development of African American rural high school students. Main effects were assessed in two related domains: concrete to abstract thinking, and self-concept development. Results indicate significant gains in both abstract thinking and ego stage. (RJM)

Examines the scientific concept of evaporation. Attempts to show how students develop their understanding through the levels of the Structure of the Observed Learning Outcome (SOLO) taxonomy. Shows how designing learning experiences to suit the learners' developmental stages in understanding a concept is paramount to the overall growth of the…

Examined whether the quality and content of everyday parent-child conversations about negative emotions differed from everyday talk about positive emotions. Found that children and parents talked about past emotions, causes of emotions, and connections between emotions and other mental states at higher rates during conversations about negative…

This study examined whether cumulative family risk would moderate the relation between regularity of Head Start attendance and child outcomes. Found that the relation between attendance and receptive vocabulary was moderated by cumulative risk, with children from higher risk families benefiting more. Regardless of family risk, attendance predicted…

Presented is a study which focused on using turtle graphics programing for geometric problem solving. The goal was to investigate changes in children's mathematical knowledge and results indicate that the LOGO environment enriched children's geometric conceptualizations and sophistication of their geometric thinking.

Examined is the relationship between junior high school students' directional reasoning about rates and numerical reasoning on proportion-related word problems. The relationship between the ability to solve context-free fraction exercises and the ability to solve mathematically similar word problems is discussed. (KR)

Described are the general problem-solving strategies and their nature and functions. The importance of integrating different types of general problem-solving strategies with content-specific teaching in mathematics classes is discussed. (KR)

Described is an activity where base-10 blocks are used to develop students' skills in reading, writing, and visualizing large numbers. An activity sheet that helps students with decimal points is included. (KR)

Discussed is the teaching method called the learning cycle and how it can be incorporated into science activities. Included are examples of how teachers and students can use the learning cycle to produce instructional materials. (KR)

Replicated and extended previous research on the relationship between oral and written communication by administering referential and explanatory communication tasks in both speech and writing to elementary school children. An independent measure of social cognitive ability was administered. (47 references) (Author/OD)

Kindergartners who had been taught to classify serials and conserve numbers through learning set procedures were retested one year later and compared with control children. Significant cognitive gains initially resulting from special intervention increased. (Author/BB)

Proposes an approach to school laboratory experiences which leads to gradual acquisition of inquiry skills based on the idea of advance organizers. Presents a design which is context familiar and can serve as an introduction to scientific inquiry. Discusses student achievement, and teacher and student attitudes. (CW)
