The purpose of this study is to investigate the structural relationships among the attitude toward science and science motivation such as affective characteristics, and self-regulated learning strategy such as cognitive factor of science achievement. 853 middle school students residing in Seoul completed questionnaires about attitude toward science, science motivation, and self-regulated learning strategy. The sample variance-covariance matrix was analysed using AMOS 20.0, and a maximum likelihood minimization function. The results are as follows: First, attitude toward science, science motivation and self-regulated learning strategy of middle school students were all found to have a significant direct effect on science achievement. Second, attitude toward science and science motivation in middle school students has a direct effect on the self-regulated learning strategy. Third, attitude toward science in middle school students has a substantial indirect effect on science achievement mediated by their self-regulated learning strategy. Forth, science motivation in middle school students has indirect effect on science achievement mediated by their self-regulated learning strategy. Therefore, in order to improve science achievement among middle school students, teachers should consider synthetically the affective characteristics such as attitude toward science and science motivation, and cognitive factor such as self-regulated learning strategy.

The purpose of this study was to investigate the effects of psychological learning environment generated by science teachers upon students' affective perceptions and cognitive learning. The subjects of the study were consist of 2.693 students from secondary school. The students' perception were examined by the tools of PLEIS(Psychological Learning Environment Instrument by Science teacher). SAMS(Science Anxiety Measurement Scale). HARS(High schools' s Attitude Related Science). and ALWSS(Attitude toward Laboratory Work Scale in Secondary school). and cognitive learning outcomes assessed to TIPS II (Test of Integrated Process Skills II ) and science test score. The results of this study suggest that positive psychological learning environment by science teacher should be offered to students for the improvement of science achievement. and learning environment will be used as an instrument of self assessment for improving science teaching strategy. Understanding of relationship among psychological learning environment, affective perception and cognitive learning will be helpful to the design of science teaching and learning process.

The purpose of this study is to investigate relationships among scientific self-efficacy, achievement in science and cognitive self-regulation learning strategy. The subjects were composed of 158 elementary school students. Data of students' self-efficacy related to science and cognitive self-regulation learning strategy measured by questionnaire were analyzed. Science achievement scores were also collected. The results indicated that self-efficacy and cognitive self-regulation learning strategy predicted science scores. The findings showed that cognitive selfregulation learning strategy mediated the relation between self-efficacy and achievement in science. Memory learning strategy, considered a cognitive self-regulation learning strategy, did not mediate the relation between self-efficacy and science scores. The implications of science education to develop students' science achievement in the classroom and the suggestions for future researchers are discussed.

The purpose of this study is to examine the effect of the backward design reflecting the process-focused assessment on science learning achievement and science learning motivation in elementary science class. The process-focused assessment to support the growth and development of learners and the backward design that seeks a learner's complete understanding can be of great help to science learning. The results of study are as follows. First, we conducted the backward design reflecting the process-focused assessment centering on 'Earth and Moon's movement' unit, and reflecting various process-focused assessment to help achieve achievement standards. Second, as a result of science learning achievement test and science learning motivation test, there were statistically significant differences in the experimental group. It is expected that the process-focused assessment reflecting the characteristics of science subject will be utilized in the school field in conjunction with the backward design.

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.

The purposes of this study were to investigate 6th-graders' use of cognitive strategies and metacognitive strategies in usual learning and testing situations, and to compare the difference in the use of the strategies by students' science achievement, learning motivation, and gender. The relationship among these strategies, science achievement, and learning motivation were also examined, and the portion of variance of explanation for achievement score was studied by a multiple regression analysis. The results showed that high-achieving students used more cognitive strategies and metacognitive strategies in usual learning and more cognitive strategies in testing situations than low-achieving students. Highly motivated students used more cognitive and metacognitive strategies than poorly motivated students in all situations. Elementary female students used more learning strategies than male students in usual learning. On the other hand, no gender differences was found to be significant in the use of strategies in testing situations. These learning strategies were significantly correlated with the science achievement and motivation scores. The cognitive strategies in usual learning accounted for the significant portion of the variance of the achievement score. Educational implications are discussed.

The purposes of this study are to investigate the effects of the Science Conceptual Model Completion Activity and Science Conceptual Model Modifying Activity on middle-school students' achievement in science conceptual learning, and to analyze if there are any correlations among their achievements by purposed activities, their cognitive level and school science achievement. For the study, 112 middle school students were sampled for three groups, which are two experimental groups (Model Completion activity group, Model Modifying Activity group) and one control group. Pre- and post-tests were taken to measure the students' achievement in science concepts, and the logical thinking ability test was administered after the implementation period. In addition, their school science achievements were analyzed. The research findings are as follows: First, the Science Conceptual Model Completion activity is more effective for middle school students' science conceptual learning than the Science Conceptual Model Modifying activity or conventional activity. Second, higher school science achievement also results in higher achievement of science concepts through the Conceptual Model Modifying activity or the Conceptual Model Completion activity. Lastly, the Conceptual Model Completion activity is more effective for the concrete operational level students to attain science concepts than formal operational level ones. Meanwhile, on the contrary, the Conceptual Model Modifying activity is more effective for formal operational level students than the concrete operational level ones.

This study investigated and analyzed the social and emotional learning components of middle school science, and high school integrated science and science inquiry experiments, which are common subjects that all students must complete. The subjects of analysis were 139 achievement standards of science and curriculum and 496 activities included in textbooks. The research results are as follows. In the case of curriculum achievement standards, 'cultural understanding' was hardly included among the seven science and social-emotional learning elements, 'numeracy' and 'creative thinking' appeared high in middle school, 'critical thinking', 'social technology' and 'ethical understanding' were included with high frequency in high school. And in the case of textbook activity, the tendency of social-emotional learning elements in middle school and high school was similar. 'critical thinking', 'creative thinking', and 'social skills' were mainly provided, while 'ethical understanding' and 'cultural understanding' were reflected in a limited way. In order to cultivate the elements of overall social-emotional learning, it is necessary to specify the achievement standards of the curriculum or to supplement the textbook activities and teaching-learning process.
