The purpose of this study is to investigate the types of concepts about atmospheric pressure of middle school students and to design a new method to improve students' understandings on atmospheric pressure. The second grade students of the middle school has been selected and examined their pre-concepts on atmospheric pressure through questionnaires and interviews. Two groups of students have been taught using the second grade science textbooks and experimental methods designed from this study, respectively. The results suggest that we need to develope various teaching methods that can improve alternative concept as well as experimental tools that can help students understand difficult scientific concepts. The reason is that once alternative concept is occupied, it is extremely difficult to fix it. In addition, the proposed experimental methods are effective in establishing the concept and understanding on atmospheric pressure.

This study is an investigation regarding the understanding of the nature of science among pre-service science teachers majoring in science education. We interviewed 22 senior students in science education who finished their internship courses. Students were interviewed individually for approximately 20 minutes each. Data from semi-structured interview were audio-recorded and transcribed for the analysis. Findings indicated that participants held more complete understanding of the nature of scientific knowledge than the nature of scientific enterprise. Their understandings of the nature of scientific method was that hypothetical-deductive method is more scientific than descriptive-narrative method and there is a single stepwise scientific method to solve problems. These results showed that they have a narrow view of the nature of science. Thus, teacher education programs need to integrate the understanding of the nature of science throughout.

This study analyzed the classroom discourse between teacher and students based on the Mehan(1979a)'s theory to examine the characteristics of the classroom discourse between teacher and students in high school statistics class. The results of this study on the structure of class showed that the statistics class in this study adopted knowledge transmission-oriented teacher-led class in which the framework of introductiondevelopment- arrangement, which is Mehan's basic 3 stages, is clearly represented. The results of examining I-R-E sequence showed that $I_T-R_T$ structure, in which the teacher asks questions and the teacher talks about the answer, frequently appeared. And the statistics class in this study was monological class in which students hardly participated. Through these results of this study, it was found that teacher should form the statistical context, in which students can participate in discourse, and build discourse learning community and induce argumentational discourse through metaprocess elicitation.

The purposes of the study are to understand how multicultural awareness and multicultural efficacy is different and to investigate the factors of multicural awareness affecting the multicultural efficacy. To achieve the goals, the study conducted surveys to examine an interrelation of multicural awareness and efficacy on 329 elementary school students in North Jeolla Province with questionnaires. First, the results showed significant differences in the multicultural awareness and efficacy based on all the ground factors. Second, it was found that elementary school students had significant relations in multicultural awareness and efficacy. Third, the multicultural awareness among elementary school students significantly affected their multicultural efficacy. The study suggests that sustaining multicultural education shall be implemented for elementary school students to have right and positive minds and various studies shall be conducted to nurture values in their lives to live together.

The purpose of this study was to develop for PLEIS(Psychological Learning Environment Instrument generated by science teachers). The procedure of validations' PLEIS is also examined. Samples of 1.274 for this study were selected from the secondary school students. It was conducted as a procedure development of the instrument with teachers' perception survey, students' perception response survey. second pilot for the measurement instrument. Findings indicate as the follows. (1) PLEIS was formed 3rd construct dimension, 9th subcategory. (2) the instrument consisting of 45-items' scale were used for psychological learning environment. (3) all item-type were applied 5-Likert Scale. (4) internal consistency of Cronbach ${\alpha}$ was 0.93.

The main purpose of this study was to examine the effects of interpretive style reading materials on high school students philosophical viewpoints on science. Subjects for this study were 137 girl students in four classes of a high school located in Daejeon city. The classes were divided into two groups: experimental groups and control groups. Students in the experimental groups were administered a series of the reading materials over thirty-six sessions. Additionally, PPP(Philosophical Perspectives Prove) was used in order to assess students philosophical viewpoints on science. Results of the study showed that the interpretive style reading materials takes effect on the change of students philosophical viewpoints on science. At the initial stage, a number of students exhibited viewpoints inclined toward inductivism. As time goes by, however, viewpoint of inductivism was decreased and view of falcificationism and view of relativism were increased. The results also indicated that the effect of intervention was stable.

The purpose of this study is to investigate middle school students' perceptions of private academy science education and of school science education in order to promote school science education. 180 middle school students who were taking a science class at a private academy were participated, and the short form of Classroom Environment Scale was implemented for the study. The results showed that the students went to an academy for supplementing school science or for getting a better grade in school. Some students, however, have different reason to go to an academy; they were kinds of silence-learners or received-learners rather than constructed-learners. That is, they didn't know how to and what to study. Students didn't have an opportunity to think scientifically and creatively from both academy and school science classes. They studied harder in science class at private academy than at school. Some students felt more favorable to and comfortable with academy teachers compare to school science teachers.

Peer assessment refers to having students, rather than the instructor, make assessments of one another's work. Peer assessment is often used as a tool to train writing skills or a tool to apply or extend learning in higher education. Park(2016) recently proposed a system which utilizes peer assessment as a part of preparatory activity for college courses. Before weekly class, students studied given material on their own, wrote a one page essay on a given question based on their reading, and assessed the essays of other students. In this study, the system was implemented in undergraduate courses at S University over 2 semesters and the results were analyzed. The reliability of weekly scores given by students was not very high, but the correlation was high between the cumulative scores given by students across weeks and the scores of the end of the term paper assessed by the instructor. Based on these findings, the possibility of utilizing the results of the peer assessments as part of the final grades was discussed.

The study objective was to understand the effects of self-efficacy and occupational value on the major satisfaction of pre-service childcare teachers. A questionnaire survey was conducted targeting 281 pre-service childcare teachers in A city. In the study results, first, pre-service childcare teachers highly perceived the self-regulatory efficacy and confidence of self-efficacy, the intrinsic value of occupational value, and the general satisfaction and perception satisfaction of major satisfaction. Second, there were statistically significant correlations between self-efficacy, occupational value, and major satisfaction of pre-service childcare teachers. Third, the self-efficacy and occupational value of pre-service childcare teachers had positive effects on the major satisfaction. Based on these study results, there should be more diverse research for the formation of proper self-efficacy and correct occupational value, so that students majoring in childcare could perceive the importance of major satisfaction and also perform their childcare jobs with high-quality.
