Abstract
Tenth grade students studied the topic of ‘The growth curve of microorganisms’, which included a computer‐assisted learning (CAL) simulation episode. The CAL episode enabled students to simulate experiments which investigated the simultaneous impact of three independent variables upon the growth curve of microorganisms (temperature, nutrient concentration and the initial number of individuals from which to start a population growth). Two classes (n = 82 students) formed the experimental group and were instructed in a combination of classroom‐laboratory work with CAL. The control group included three classes (n = 99 students) who were taught the topic in the classroom‐laboratory work setting only. Five teachers taught the five classes, three periods weekly and the study lasted 4 weeks. The students’ previous knowledge in the topic to be learned and their academic achievement were assessed with pre‐ and post‐tests, respectively. The data for each lest were treated with a two‐way analysis of variance. The results showed that the two study groups did not differ in their previous knowledge and no significant differences were found by gender within and between the groups. The post‐test results on academic achievement indicated that students in the experimental group achieved significantly higher means scores than the control group. No significant gender differences on academic achievement were found within each group. The results affirm that: (a) computer simulations, in which three variables are manipulated simultaneously in one experiment, can be integrated as short episodes in the existing biology curricula; (b) high school students can perform computer simulations which require the skills of simultaneous manipulations of three variables in one experiment, problem solving and decision making; (c) girls and boys in the experimental group exhibited these skills at a similar academic level of achievement.Keywords
