TGT (teams-games-tournaments) cooperative learning is suggested as a method which enables both the individualized teaching-learning and the small group learning in students-centered open education. This study investigated the instructional effects of the pre-learning program applied by ICT-based TGT cooperative module for science museum excursion regarding of the earth and the moon on the science related attitude according to gender difference in elementary school science class. Three classes of third graders (N=87) at a elementary school were randomly assigned to the ICT-based TGT cooperative learning group, the ICT learning group, and traditional learning group. The students were taught about the planning of exploring the moon in the chapter of the earth and the moon, for 1 class hour. Prior to the instructions, the TOSRA(test of science related attitude) and achievement test were administered. Two-way ANCOVA results revealed that the scores of the ICT-based TGT cooperative learning group were significantly higher than the other learning groups for most of the TOSRA scales. However, there was a little significant difference among the three groups in the three distinct scales of TOSRA, Normality of Scientists, Leisure Interest in Science, and Career Interest in Science. Advantage/disadvantage and usefulness of ICT-based TGT cooperative learning were also 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.

This study, based on literature review and theoretical discussion, reinterprets the learning environment instruments from cultural perspectives and suggests the applicability of learning environment instruments for understanding science classroom cultures. To do this, the existing learning environment instruments are first investigated and compared in terms of their features and utilizations appeared in previous studies. The learning environment instruments are then reinterpreted in the light of culture. Finally, we suggest the possibilities to use the learning environment instruments to understand science classroom cultures. The results of this study can be summarized as follows. First, the learning environment instruments, by interpreting them culturally, could be interpreted in cultural ways and used as the alternative ways to explore science classroom cultures. Second, the learning environment instruments, such as WIHIC and CLEQ, could be interpreted both along the dimension of phenomena in classrooms and the dimension of students' psychology in order to investigate science classroom cultures. Third, the instrument items could be interpreted culturally in different ways according to the description types of instrument items. Thus, when learning environment instruments are used in culture research, the description types should be sufficiently taken into account. Based on the results of this study, educational implications are discussed in terms of exploring classroom cultures and of culture research.
