The purpose of this study is to explore the effects of self-directed field learning practices on student’s academic achievement and self-directed learning characteristics regarding the level of learning ability. To conduct this study, 196 students of high school students in Busan were chosen and parted into either the experimental group (98 students) or control group (98 students). Each group is classified into three categories: high level (24 students), middle level (50 students), and low level (24 students) according to the level of learning ability by the academic achievement pre-test. The areas chosen for experimenting this study range from Dusong peninsula, Molundae in Saha-gu, Songdo in Seo-gu, Pusan. Then the inquiry-model of self-directed field learning which focuses on learner-centered activity was designed based on theories concerning field learning and self-directed learning, and was applied to the experimental group. In conclusion, this teaching method using self-directed field learning is expected to improve academic achievement in science subject and increase students’ self-directed learning characteristics regardless of the students' level of academic achievement.

This study aimed to investigate the changes in learner's scientific conceptual formation and academic achievement after a CoRe-based science lesson. For this study, two classes of the 6th grade of elementary school were divided into an experimental class and a comparison one. The students of the experimental class received CoRe-based science lesson and those of the comparison one received general science lesson. Both of the classes studied 'unit 1. A change in the weather', which is a part of content of 6th grade science text book. The results of this study were as follows. First, in the questions of invisible and abstract phenomena, students had misconceptions based on their experience in real life, or did not understand the fundamental causes of that phenomena. But after receiving lessons respectively, experimental class generally showed at a higher rate of understanding the causes of the phenomena than comparison class. Second, CoRe-based science lesson was more effective to improve students' scientific conceptual formation than the general science lesson. Moreover, when two classes were respectively divided into two groups as high and low-level groups according to their pre-test achievement records, the CoRe-based science lesson was more effective to learners of the high-level groups. Third, CoRe-based science lesson was more effective to enhance students' academic achievements than the general science lesson, especially to learners of the low-level groups.

The purpose of this study is to examine the effect of peer mentor on academic achievement of mentee and views on nature of science. The experimental group was consisted of 20 mentor students, formed as a high level being less than 20% of achievement test, and 20 mentee, low level less than 15% of that. The mentoring activities were conducted 23 times for 8 weeks and progressed for 15~30 minutes after the teacher's main classes. During the mentoring activity, studying materials were provided to students and mentees asked to mentors for the parts which were difficult to understand among the contents of classes and got replies by arranging studying materials. As the results of this study, First, peer mentoring activity was shown statistically meaningful effects and improved the academic achievement in mentee's group than traditional classes (p<.01). But, there was no meaningful effects on mentor's achievement (p>.05). Second, the students who took part in the peer mentoring activity said that it was a good chance to have a close relationship between mentors and mentees. Also, the science recognition of the students were changed positively even though the science is hard and difficult to memorize, but interesting subject included the experiments. Third, the satisfaction of the peer mentoring activity is high both mentors and mentees (p<.01). Fourth, according to mentees' positive attitude, and as the level of closeness is higher, the academic achievement was increased. Based on this study, if teachers organize mentoring team effectively according to their closeness, one can expect the positive change of recognition on science as well as academic achievement of mentees.

The purpose of this study is to guide and apply gettable and accessible materials around everyday life into classroom instruction, and to find out their effects on student academic achievement. In order to achieve it, this study was tried to develop and guide available materials around life in teaming activities, to provide a preliminary assignment that could apply the available materials, and to compare its academic achievement to one from field trip loaming. For the hypothesis testing, first, the experimental and comparing classes were selected based on the results of basic learning diagnostic evaluation, which conducted by the researcher being served as a full-time science teacher of the third and sixth grade of K elementary school in Kwangju for 2 years. Secondly, the instructional use of the available materials around life was applied to the experimental class. Also, the instructional use of the existing materials was applied to the comparing class. Finally, for the testing of the effects on academic achievement, the posterio test was implemented after conducting the experimental instruction in knowledge·understanding, inquiry process, and attitude domains classified by the unit characteristics. Using SPSS/WIN program the t-test was performed in order to compare the differences between the two groups. Major findings were as follows: 1) In the achievement test of knowledge·understanding domain, there were no significant differences at the 5％ level between the experimental and comparing classes. It could be difficult to say, therefore, that the instructional use of the available materials around life was more effective than the instructional use of the existing materials. However, it had some effects on differences between the third grade final achievement test and sixth grade experimental class. 2) In the achievement test of inquiry process domain, there were some significant differences in that the sixth grade experimental class was higher than the third grade out-of classroom experience unit. It was indicated that the instructional use of the available materials around life had some effects on improving the students' inquiry ability 3) In achievement test of attitude domain, there were some significant differences. It was shown that the self-evaluation test of the sixth grade experimental class unit was higher than that of the third grade out-of classroom experience unit; Especially, the learning activities in the experimental class were more active, and the experimental practice ability was improved. It was presented that the instructional use of the available materials around life had some effects on the students' academic achievement in attitude domain. It was concluded from this study that the instructional use of the available materials around life was less effective on Knowledge understanding domain, but was effective on improving their scientific inquiry ability and interest on science education.

The purpose of the research was to find out the difference in students' academic achievement in Technology Education between students with a lecture, those who perform a content-related project after a lecture, and those who carry out a content-related project without a lecture. The results of this study are as follows. First, taking advantage of both a lecture and project-based lesson led to better achievement than using only a project in Technology Education subject of an academic high school in academic achievement in 'knowledge' area. I infer that it is because they reviewed what they had learned in a lecture and the preparation and practice of the project caused them to memorize it. Second, there was not a meaningful difference in academic achievement in 'understanding' area among the group with a lecture, the one with both a lecture and a project, and the one with only a project. However, considering the comparison of averages and the p-value of F-test, I can deduce that the test outcome influences students with a lecture and a project positively in terms of academic achievement. Third, there was not a meaningful difference in the academic achievement in 'adaptation' area among the group with a lecture, the one with a lecture and a project, and the one with a project. I can conclude that those results are because the difficulty level of evaluation was high and they produced a model just by copying textbook contents.

Utilizing the quantitative analysis methodology of questionnaire, the study explores the differences in the factors of achievement motivation, learning mathematics attitude and learning mathematics self-confidence and also the relationship between mathematics academic achievement and these factors in three areas in China. The following conclusions are drawn: 1. The subjects from different development level areas have significant differences in motivation, attitude and self-confidence in mathematics; 2. The subjects from different areas who possess the same ethnic group have significant differences. But the subjects from same area who possess different nationalities have little difference. It can be concluded that that the differences in these factors can be contributed to regional differences, rather than to ethnic differences; 3. The subjects from undeveloped areas have significant gender differences, and the levels of males are higher than those of female.
