In this study, high school students' environmental conceptions and attitudes, and their relationships with affective variables (self-esteem, enjoyment of science lesson, and leisure interest in science) were investigated. Students' environmental conceptions were found to be low, and male students' environmental conceptions were higher than female students. However, the environmental attitudes of female students were more positive than those of male students. There were no differences between male and female students in the ecocentric attitudes, but male students had more egocentric attitudes than female students. Students of higher prior science achievement level possessed higher level of environmental conceptions than their counterparts. Among the affective variables studied, leisure interest in science was significantly correlated with environmental attitudes.

The purpose of this study was to investigate the instructional effects of a problem solving model on students' achievement, science process skills, and perceptions of science activities. The problem solving model was developed on the basis of the SSCS (Search, Solve, Create, Share) problem solving model while considering Korean educational situations under a national curriculum. The model developed is composed of 4 stages; identify, solve, create, and share. In this research, the treatment and control groups (6 classes) were selected from a middle school in Seoul and taught about the separation of mixture for four weeks. Prior to instruction, the Group Assessment of Logical Thinking and the Learning Approach Questionnaire were administered, and their scores were used as covariate and blocking variable, respectively. During instruction, classroom observations for each group were conducted with a researcher-made checklist. Immediately following the instructions, students' achievement, science process skills, and perceptions of science activities were measured by a researcher-made achievement test, the Middle Grades Integrated Science Process Skills Test(MIPT), and the Perceptions of Science Activities Questionnaire, respectively. The results indicated that students in the treatment group achieved significantly better than those in the control group. Although students in the treatment group were found to use more science process skills correctly during their science activities, the MIPT scores of the treatment group were not significantly higher than those of the control group. No interaction with students' learning approach was found for both students' achievement and science process skills. On the questionnaire of students' perceptions of science activities, the treatment group showed more positive perceptions and interest than the control group. Educational implications are discussed.

This study investigated the influences of reciprocal peer tutoring (RPT) strategy on middle school students' science achievement, self-efficacy, perception of instruction by grouping method and science achievement level. Eighth graders from a middle school in Seoul were assigned to comparison, homogeneous RPT, and heterogeneous RPT groups. The students were taught about 'separation of mixtures' for 8 class hours. After the instructions, a science achievement test consisting of three subtests (knowledge, understanding, and application), a self-efficacy test, and a questionnaire about the perception of instruction were administered. The analysis of the results revealed that the scores of heterogeneous RPT group, regardless of the students prior science achievement level, were significantly higher than those of the other groups in the knowledge and understanding subtests, and the self-efficacy test. The scores of homogeneous RPT group were significantly higher than those of the comparison group in the knowledge subtest but not in the understanding subtest and the self-efficacy test. The low-level students in heterogeneous RPT group performed better in the science achievement test and the application subtest than those in the other groups. The high-level students in RPT groups performed better in the science achievement test than those in comparison group. However, there was no significant difference for the application subtest scores of the high-level students of the three groups. Most students in RPT groups perceived positively on the instructions. The students in heterogeneous RPT group and low-level students especially showed more positive perception of the instruction than those in homogeneous RPT group and high-level students.

This study investigated the effects of group processing in cooperative learning using task-oriented reward on students' science achievement, science learning motivation, and attitude toward science instruction. Eighth graders (N=58) selected from a middle school in Seoul, were randomly assigned to either the treatment or comparison group, and taught on the 'Separation of Mixture' over 8 class hours. The treatment group received cooperative learning using task-oriented reward containing group processing (GCL), while the comparison group received cooperative learning using task-oriented reward without group processing (CL). Significant interactions between the instruction and prior achievement level were found in the achievement and the attitude toward science instruction. High-level students in the GCL group performed better than those in the CL group, while low-level students in the CL group performed better than their counterparts.

This study investigated the effect of generative concept maps according to learning achievements and cognitive load. A total of 78 students in the first grade of middle school participated in this study. Before the experimental treatment was implemented, students had to fill out a questionnaire assessing prior knowledge. The study was designed where all the students were presented the same learning contents regarding photosynthesis; however, the two experimental groups were provided with different concept map methods: a learner-generative concept map (GCM) and an instructor-provided concept map (PCM). GCM students were asked to make a concept map by themselves in small groups while they are reading material. PCM students were instructed to study in small groups in order to read the material; however, they were provided a concept map developed by their teacher. The control group (CG) had the teacher present the learning contents in traditional lecture format with no accompanying concept map. The results show that there were significant differences in the achievements among the groups. CG showed higher achievement than both the experimental groups. There was also a significant difference in cognitive load. Although the GCM group did not obtain higher achievement than the other groups, the GCM group showed higher mental effort and lower physical fatigue than the other groups. The GCM group might have invested more effort to find and connect ideas when drawing their concept map with peers which is unlike the conditions for the PCM group and CG. In conclusion, we should consider applying GCM in teaching and learning design in order to increase learning achievement and decrease extraneous cognitive load.

In this study, a conceptual change model for effective laboratories was developed and its instructional effect on students' achievement, the acquisition of scientific conceptions, and the attitudes toward science was investigated. Considering several conceptual change models in literature and Korean educational situations, the conceptual change model was developed. The model consists of 5 stages; preliminary, prediction, exploration, consolidation and reconstruction, and application. The treatment and control groups (2 classes) were selected from a middle school in Seoul, and taught about the changes of states, density, and dissolution for three weeks. Prior to instruction, the Group Assessment of Logical Thinking and the Learning Approach Questionnaire were administered, and their scores were used as covariate and / or blocking variable. To examine students' alternative conceptions before the instructions, a pre-conceptions test was also administered. After the instructions, students' achievement, the acquisition of scientific conceptions, and the attitudes toward science were measured with a researcher-made achievement test, a post-conceptions test, and the subtests of the Test of Science-Related Attitudes, respectively. The results indicated that the score of the treatment group was significantly higher than that of the control group in the post-conceptions test. The students in the treatment group had also less alternative conceptions than those in the control group. However, there were no significant differences for the achievement and the attitudes toward science. Educational implications are discussed.

The instructional influences of cooperative learning strategies, which emphasize mutual interdependency of learners, group goal, and individual accountability, upon students' achievement, the attitude toward science instruction and the perception of learning environment were investigated. Before instruction, the prior knowledge test about atoms and molecules, the test of attitudes toward science instruction, and the perception questionnaire of learning environment were administered, and the grade in the previous mathematics course was obtained. These scores were used as covariates. Mid-term examination score was used as blocking variable. For instruction, three different strategies-traditional individual learning, small group learning, and cooperative learning-were used and teaching materials for the units of mole and stoichiometry were also prepared. After instruction, the researcher-made achievement test, the test of attitudes toward science instruction, and the perception questionnaire of learning environment were administered. The perception questionnaire of group activities was also administered to the two treatment groups. In the quantitative subtest, the scores of cooperative learning group and small group learning group were significantly higher than those of traditional individual learning group. However, the cooperative learning group's scores in the achievement test and the qualitative subtest were significantly higher than those of small group learning group and traditional individual learning group. The students in the cooperative learning group were found to have the most positive perception of learning environment but to have similar attitudes toward science instruction. No interaction between the treatment and the level of the previous achievement was found in any of the analyses. In the perception questionnaire of group activities, students in both small group learning group and cooperative learning group exhibited positive perception of group activities. However, students in the cooperative learning group tended to think that their activities were related with their group's success. Educational implications are discussed.
