The Rural Outreach Chemistry for Kids (R.O.C.K.) program was designed as a service-learning project for students at Saint Francis University to serve the local communities by organizing chemistry activities in high schools. It was initiated in 1995 and has involved a large number of Saint Francis University students and local high school students.…

To detemine the effectiveness of the Individualized Audio-Tutorial (IAT) method of instruction, an IAT unit in biology was implemented in ninth grade classrooms in an urban school in Israel, and student achievement was measured in relation to gender, academic background in mathematics and biology, and IQ levels. The 180 subjects were randomly…

This study investigated and compared the level of initial and long-term retention of frog internal anatomy among students using an interactive CD tutorial, a desktop microworld, and conventional frog dissection. Students' anxiety toward science was also compared across the three treatment groups and between genders. Additional data on students'…

Describes study that investigated achievement and motivation effects related to locus of control and learner control on seventh and eighth grade Hispanic students completing a computer-assisted instruction (CAI) science lesson. Use of the Intellectual Achievement Responsibility scale is discussed, and a questionnaire that assessed student…

Describes study conducted with undergraduates in India to investigate the selection of suitable learning strategies in science instruction. Highlights include six independent and seven group learning strategies; components of students' learning potential; the influence of different components of learning potential on three achievement levels; and…

In this paper we present a simple set-up that illustrates the mechanism of sap ascent in plants and demonstrates that it can easily draw water up to heights of a few meters. The set-up consists of a tube with the lower end submerged in water and the upper one connected to a filter supported by a standard filter-holder. The evaporation of water…

This paper presents the designs underlying an IPI approach to ninth grade science implemented in the Jamesville-DeWitt schools in New York State. Briefly described are the generalizable instructional model, evaluation systems for assessing individual performance and the effectiveness of the instructional program and the support systems which make…

The purpose of this study was to investigate the effects of learning strategy and summarization within a computer-based chemistry and physics program. High school students worked individually or in cooperative dyads to complete science instruction; half of them completed summaries over the instructional content when directed to do so. The study…

Describes a study that explored the impact of using interactive video in a seventh grade earth sciences curriculum. The effectiveness of interactive video and traditional text instructional methods in different settings (computer lab versus classroom) are compared, gender differences are examined, and recommendations for future research are given.…

Describes a study of high school students that investigated the impact of computer-assisted learning (CAL) integrated with classroom-laboratory instruction versus classroom-laboratory work alone on students' achievement and mastery of science process skills in a microbiology course. Posttest scores are compared and the curriculum integration of…

A challenge for urban systemic reform initiatives in science education has been to achieve local, state, and national standards for teaching and learning. We have collaborated with teachers in the Detroit Public School System to design project-based curriculum materials that contextualize the learning of science in meaningful real-world problems,…

This packet, designed for teachers of Job Corps participants is intended to familiarize them with the contents and presentation methods of the competency program developed to help students prepare for the General Educational Development (GED) (high school equivalency) tests. The first part of the package contains a teacher's guide that presents an…

Describes a study of ninth graders that investigated the effects of learner and program control over content review in science-related computer-assisted instruction (CAI). Results of posttests, continuing motivation measures, and attitude questions are discussed; and future research is suggested. (35 references) (LRW)

In this paper we discuss the development and implementation of a questionnaire that measures preparedness to teach secondary school science with information and communication technologies (ICT). The questionnaire was designed for the purpose of evaluating the effectiveness of instruction in a science education unit in a Graduate Diploma teacher…

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)
