In this empirical study we examined the effect of a literacy-infused science intervention on fifth grade economically challenged students' science achievement in the curriculum-based and standardized assessments. A total of 27 treatment students and 20 comparison students from two intermediate schools in a rural district in South Texas in the…

This article identifies realistic, research-based computer simulations that are capable of stimulating student decision making. Also discussed is a recent category of computer programs, probeware. Students use a sensing device (probe) to measure physical characteristics and transmit results to a computer which collects, stores, and displays the…

Synthesizes the results of three case studies of middle school classrooms in which computer and video materials were used to teach topics in earth and space sciences through interactive simulations. Describes specific instances in which common current practice is problematic. Makes suggestions regarding improved design principles for such…

This study involved students using simulation software in all phases of the learning cycle. Research on the use of simulations in science education has shown that the simulations can be used effectively in preinstructional and exploratory activities. Preinstructional and exploratory activities elicit and challenge students' alternative…

A systematic study was conducted with a group of 10- to 12-year-olds using computer assisted instruction in a unit on fire which included a computer simulation of combustion. Three research questions were addressed to learn more about how the computer experience challenged the students' preconceptions: what the students thought the computer knew,…

Trying to change the predictive rule for the sinking and floating phenomena, students have a great difficulty in understanding density and they are insensitive to empirical counter-examples designed to challenge their own rule. The purpose of this study is to examine the process whereby students from sixth and seventh grades relinquish their…

This 10-day study compared the effects of alternative ways of using microcomputer simulations on the achievement and attitudes of sixth- and seventh-grade science students (N=173). Nine classes were randomly assigned to one of four treatments: (1) microcomputer simulations; (2) laboratory activities; (3) a combination of simulation and laboratory…

Describes a study designed to assess the effectiveness of 2 science simulation programs for 11- and 12-year-olds in a developing country (Guyana). Computer-assisted learning (CAL) results are compared with results from written assignments, effect size is discussed, gender differences are examined, and ability levels are considered. (14 references)…

Describes the development of a science-based computer simulation for sixth graders on global warming that integrated research, writing, speaking, science lab, and computer skills. Highlights include teacher/librarian collaboration; problem-based learning; building knowledge; design and planning; creating Web pages; gathering, organizing, and…

This report describes a training project undertaken as part of the Bank Street College Mathematics, Science and Technology Teacher Training Project (MASTTE) to introduce teachers to "The Voyage of the Mimi," a 13-part television drama and multimedia package designed to supplement the regular curricula for science and mathematics in the…

This study investigated the types of tactics and strategies students used in working with computer simulations and examined if the skills acquired when using the computer simulation could be applied in other settings. Sixth grade students (N=50) from three different schools participated in the study and were observed over a period of six weeks.…
