The purpose of this study is to investigate the effects of problem-solving inquiry teaching using concept sketches on conceptual changes about plate tectonics and science-related attitudes. The subjects of this study were two classes of second-year students of K high school located at Anseong in Gyeonggi Province. Before instruction, a conceptual test was conducted to survey student's preconceptions about plate tectonics. The control group took a traditional lesson, while the experimental group was applied to problem-solving inquiry teaching using concept sketches. After the inquiry instruction, TOSRA (Test of Science-Related Attitudes) was administered to find out changes in science-related attitudes of the two groups. The results of this study are as follows. The experimental group understood concepts of plate tectonics better than the control group, which means that problem-solving inquiry teaching using concept sketches was more effective in students' conceptual understanding. Science-related attitudes of the experimental group showed a significant change in the categories of 'normality of scientists', 'pleasure of science lessons', and 'interests on science as a hobby'. In conclusion, the instruction of problem-solving inquiry using concept sketches produced students' positive changes in conceptual understanding about plate tectonics and science-related attitudes.

In this study, Jigsaw III cooperative learning strategy and traditional learning strategy have been applied to the 'electricity' chapter of grade 8 science textbooks to know the effects of learning strategy, gender, and GPA on the students' science achievement and science learning attitude of middle school female students in gender-separated classes. For this purpose, 143 students of 4 classes in separated classes were chosen from a middle school in Daegu. One female class and one male class were assigned to the experimental group and other female class and male class were assigned to the control group. Traditional learning strategy was applied to the control group and the Jigsaw III cooperative learning strategy was applied to the experimental group. Four worksheets for expert groups were used for 18 hours through 5 weeks. Both tests for science achievement and learning attitude were administered as pre and post test. The test results were analyzed through analysis of covariance(ANCOVA) as pre test score as covariant The overall conclusions of this study were as follows: The Jigsaw III cooperative learning has improved science achievement, especially on subjective-type questions, of female students and mid-lower level students. The Jigsaw III Cooperative Learning has also improved self-directed attitude toward science learning. Female students have expressed more positive opinion about the Jigsaw III cooperative learning.

The purpose of this study is to examine the perception of college students about English classes using TED talks and to examine whether TED talks are appropriate as a learning material for college English. As a college English subject, 50-60 minutes of online classes were conducted for one semester where TED talks were used, and the data collected by conducting a survey on learners' English learning motivation, interest, attitude, satisfaction, and learning effect were analyzed utilized SMART PLS 3. The results are as follows. First, English learning motivation had a statistically significant effect on learning attitude while it did not affect the learning satisfaction. Second, the level of interest in the TED Talk-using class had a positive effect on the learning attitude and satisfaction. Third, the learning attitude positively affected the learning effect perception. Fourth, satisfaction with the TED Talk class had a positive effect on the learning effect perception. In conclusion, English classes using TED talk can increase the interest and satisfaction of learners, and induce active class participation, which lead to a positive perception in learners' learning effects. Therefore, this study implies that TED talks are valuable and significant enough as materials in college English classes.

The purpose of this study was to find out the effect of the science lesson emphasized creativity and character on the creativity and science related attitudes of elementary school students. To conduct this study, 'Unit 1. Weighing', which is a part of content of 4th grade science text book, was analyzed and 11 science lessons emphasized the elements of creativity and character were developed. One experimental group and one control group of 4th grade students were selected to perform a prior investigation. Then the experimental group attended developed science lessons and the control group attended the traditional science lessons based on the text book and teacher's guide. After conducting lessons, a post investigation was performed for each group and the results were analyzed to produce the following conclusions. First, the science lesson emphasized the creativity and character was more effective than traditional one to improve students' creativity. Especially, fluency, originality and abstractness in sub-elements of creativity, were improved meaningfully. Second, the science lesson emphasized the creativity and character was more effective than traditional one to enhance students' science related attitudes. Especially, in sub-domain, the attitude about scientific research and the application of scientific attitude were enhanced meaningfully. Consequently, science lesson emphasized the creativity and character was thought to have a positive effect on improving the creativity and science related attitudes of elementary students.

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 the study was to develop project based math learning using future prospective jobs to find out its effects on elementary school student's attitude toward mathematics and career awareness. Also, this study aims at implementation of this project based math learning program in school math education. The project based math learning using future prospective jobs was conducted through 19 lessons for 7 weeks. As a result, the project based math learning using prospective jobs is turned out to be effective on developing attitudes on mathematics and career awareness positively.

The purpose of this study was to identify the influence of using the concept cartoons about middle school students' science attitude in the lessons on water cycle unit. For the purpose, they were developed to the learning program with concept cartoon and the instrument for the science attitude which has four categories; attitudes about science, attitudes about science subject, learning motives for science subject, and scientific attitudes. The research method was designed to quasi-experimental design. The concept cartoon was provided to the experimental group during nine lessons. Before and after the lessons in all two groups, the pre-post tests with the instrument were performed. The results from twice t-tests were shown that the domain of learning motives for science subject was only improved. From these, it were indicated that the concept cartoon was not effective all areas in science attitude, therefore the use in science lessons need to be restricted within narrow purpose.
