This study aims to investigate the effects of science writing activities on the students' science-related attitude, motivation for learning science, and academic achievement. One hundred and twenty seven second graders of a middle school located in Gyeonggi province participated in this study. The experimental group performed science writing activities, while the comparative group performed problem solving activities at the end of the regular science lessons over 30 class hours. For the students' science-related attitude and motivation for learning science, TOSRA, PALS, and MSLQ were used with some modification and supplementation. For the students' academic achievement, scores on science examinations were used. The results of this study are as follows: First, the test of the science-related attitude showed that science writing activities have positive effects on the cultivation of sciencerelated attitude, as for the sub-factors, 'attitude towards scientific inquiry,' 'pleasure of science lessons,' and 'active attitude towards science'(p<.05). Second, the test of motivation for learning science showed that the science writing activities had positive effect on the improvement in students' motivation, as for the sub-factors, 'difference in values on task' and 'self-efficacy'(p<.05). Third, science writing activities are effective on improvement in the students' academic achievement(p<.05), especially on the high-level achievement group.

The purpose of this study is to examine the effects of applying the Question-Answer Relationship (QAR)strategy on the attitude toward science of the elementary fifth grade students whose learning styles have beenidentified. The population of the study constitutes the total of 97 elementary fifth grade students who wereassigned into a comparison (n=48) or experimental group (n=49). To understandhow the QAR strategy potentially influencedscientific attitude, both groups were surveyedin the areas of scientific attitude before and after the experiment. TheKolb's Test was used to identifythe students' learning stylein the experimental group. According tothe learners' learning style, the results have been compared and analyzed. The results of this study are as follows:First, the findings revealed a significant difference in the experimental group students' attitude toward sciencecompared to the comparison group. Second, four learning styles were identified among the studentsin theexperimental group: a) Accommodators (46.9%), b) Convergers (24.5%), c) Divergers (20.4%), and d) Assimilator (8.2%). Following the data analysis, there was no meaningful statistical difference between four groups oflearning styles with respect to their scientific attitude.Applyingthe QAR strategy in a science class seemed toimprove the accommodators, convergers, and divergers' scientific attitude positively.

Comparative studies using large-scale data such as TIMSS, PIRLS, and PISA inform us of the effectiveness of each educational system. Even though samples in the large-scale studies were representative, admitting potential discrepancy when applying the findings of the large-scale studies to local educational system is still needed. This study examines the structural relationship among students' attitude towards science, learning support from teachers, school life, and science academic achievement with both large-scale data and local comparative study data utilizing same variables. Responses on the TIMSS 2019 of 5,554 Korean seventh-grade students and National Assessment of Educational Achievement (NAEA) 2019 of 6,365 third-grade middle school students were used. The results indicate that: a) school life did not affect the science achievements in both data. However, in NAEA 2019, students' attitude mediated the relationship between school life and science achievement; b) learning support from teachers had a significant impact on TIMSS science achievements, and also had positive effect on achievement through students' attitude in TIMSS. On the other hand, learning support had a positive effect on achievement only when student's attitude mediated the relationship in NAEA; c) students 'attitude toward science had positive effect on science achievement on both data; d) the impact of gender was different on school life, academic achievement, students 'attitude towards science, and learning support from teachers on both data; and e) the impact of the number of books differed as well. There were differences in results between the international and domestic research, which inform us that we need to pay attention when interpreting the domestic environment through the results of international research.

The purpose of this research is to find out effectiveness of geometry learning through spatial reasoning activities on mathematical problem solving ability and mathematical attitude. In order to proof this research problem, the controlled experiment was done on two groups of 6th graders in N elementary school; one group went through the geometry learning style through spatial reasoning activities, and the other group went through the general geometry learning style. As a result, the experimental group and the comparing group on mathematical problem solving ability have statistically meaningful difference. However, the experimental group and the comparing group have not statistically meaningful difference on mathematical attitude. But the mathematical attitude in the experimental group has improved clearly after all the process of experiment. With these results we came up with this conclusion. First, the geometry learning through spatial reasoning activities enhances the ability of analyzing, spatial sensibility and logical ability, which is effective in increasing the mathematical problem solving ability. Second, the geometry learning through spatial reasoning activities enhances confidence in problem solving and an interest in mathematics, which has a positive influence on the mathematical attitude.

The purpose of this study was to examine the effects of the game application learning 8th graders' scientific attitude, which was utilized as a strategy to improve the teaching skills and methods in the lesson of 'the history of the earth and diastrophism'. The subjects of this study were 120 students of 8th grade at a middle school located in a metropolitan city in Korea. To start off with homogeneity of a group, this study recruited participants by the results of a diagnostic test taken early in the year and a mid-term examination taken at the end of April. As a result, a total of 4 male classes that showed similar results on the two tests were selected and divided into two groups: one in experimental and the other in control. In addition, the top 20% students and the low 20% students were chosen for comparison of their scientific attitudes based on the results of the mid-term examination. The traditional teachings were offered to the control groups while the experimental lessons with the game activities performed at the stages of application and summary in teaching were offered to the experimental groups over 10 periods. Results of the pre- and post-test on the students' scientific attitude demonstrated that there was a statistical significance between the two groups, which suggested that the experimental group showed a meaningful improvement in the scientific attitude after experimental intervention lesson activities with game applications. Also, the more meaningful improvement in the scientific attitude was found in the lower group than in the higher group. It implies that lessons with the game activities motivated the students to voluntarily participate in school science learning by enhancing their interests. Therefore, it is suggested that game application learning be a new teaching-learning material that helps to encourage learners to actively participate in middle school science learning.

This study is a research about the effect on achievement, retention and attitude of learning descriptive statistics with the computer software. For this study, 60 students are randomly divided two groups, one is an experimental group using software, the other one is a control group using lecture type of learning statistics. For the analysis, both groups are divided three subgroups according to mathematical ability. Also the topic "descriptive statistics" is divided by 5 subtopics. The test is divided three parts(computation, concept and application) according to knowledge type. The attitude toward statistics is investgated with questionaire and interview with both groups. The achievement test is taken after 8 class periods. The retention test were administered together six weeks after achievement test. The experimental group achieved significantly better than in concept type while the control group performed significantly better than the experimental group in computation type. With respect to the attitude toward statistics, lower ability students may have been negatively affected by the use of software.
