Discussion of how the nature and use of visual and verbal meaning-making systems vary across formats. Focuses on a comparative study of CD-ROMs and printed books dealing with scientific concepts in upper primary grades. Topics include linguistic and visual semiosis; the use of images; and meanings in images. (Author/LRW)

One direction that science education reform has taken is an investigation into the content knowledge structure, instructional beliefs, and teaching practices of middle school, high school, and college science teachers. This research study follows that same path to determine whether systematic differences exist between academic levels on these…

A study determined if using specific reading strategies would improve students' grades in science. Subjects, 21 fifth-grade students in an urban area school, studied four units of science--two units using the strategies outlined in the series teacher's manual, and two units using semantic mapping, cloze exercises, graphic aids, and vocabulary…

Findings are reported from a study which compared the effectiveness of specialized and general fifth-grade science teachers (N=86). A causal model, derived from path analysis, was constructed to explain the apparent lack of effect on student achievement of the superior preparation and instruction of specialized teachers.(IAH)

Studies were undertaken in four counties in North Carolina to determine if the learning styles of African American children described by J. Hale (formerly Hale-Benson) (1986) could be identified among African American high school males through the use of the Myers Briggs Type Indicator (MBTI). Learning style differences between minority (n=184)…

A study analyzed the effects of classwide peer tutoring on science vocabulary spelling achievement for three language groups in one school's sixth grade. The groups consisted of: (1) Spanish-dominant and limited-English-proficient (LEP) students (n=8); (2) students proficient at grade level in both Spanish and English (n=14); and (3) monolingual…

The purpose of this study was to make comparisons between intermediate grade black pupils in an individualized, computer-supported instructional program and intermediate grade black pupils who were in a traditional, self-contained classroom instructional program. Specifically, the basic problem was that of determining the extent to which an…

Describes a study that compared the effects of cooperative and individual learning on fifth and sixth grade student performance and attitudes during interactive videodisc instruction for science. The use of heterogeneous ability groups is discussed, time on task is examined, and further research is suggested. (22 references) (LRW)

The main objective of this program was to produce animated educational material to stimulate students' interest and learning process related to the sciences and to measure their impact. The program material was designed to support middle school educators with an effective, accessible, and novel didactic tool produced specifically to enhance and…

The purpose of this study was to investigate the effect of implementing cooperative learning and objectives with computer-based instruction (CBI). Subjects were 125 fifth and sixth grade students. Cooperative dyads and individuals worked through a CBI earth science program that contained either instructional objectives, advance organizers, or no…

The purpose of this study was to assess the effectiveness of two generative learning strategies, concept maps and manipulation of objects, and to determine if either works better with individual learners or in cooperative learning groups. A total of 80 sixth-grade students in science education were randomly assigned to group or individual…

To analyze a student's conceptual changes, analyzing transcriptions of writing and verbal statements may not provide enough information. In a study of 25 sixth graders learning about matter and molecules, concept mapping of students' stated ideas was used to analyze the kinds of organizational changes the students made to use new science…

This document presents a series of 14 lesson plans in an interdisciplinary Spanish unit on "La isla del encanto/The Enchanted Island." The materials were prepared for students in grades 5 or 6 who have had basic Spanish instruction in previous grades. The students should also be familiar with basic concepts in English such as math…
