This study is a quasi-experimental study to find out the effect of school library-assisted instruction on middle school students' self-directed learning ability in Home Economics Education. For this purpose, the following research questions were established. 14 hours of school library-assisted instruction and traditional lecture were carried out to 164 9th grade female students(82 of experimental group, 82 of comparison group) of a girls' middle school in Jinju, Gyeongnam. To verify the instructional effect, a pre-test and a post-test for self-directed learning ability were carried out. SPSS 12.0 was used for statistical analysis. For statistical analysis, reliability analysis, frequency analysis, x2-test, t-test, repeated measures-ANOVA, and bivariate analysis were used. The results of this research were as follows: First, there was a statistically significant difference between experimental group and comparison group in the self-directed learning ability in all the subordinate items. Second, the change of self-directed learning ability by grade within the experimental group showed no interactional effect in all the sub-items except problem solving ability. Problem solving ability showed a meaningful difference in the rate of grade rising in accordance with academic achievement level and a higher synergy effect was shown in the low academic achievement group. Third, the experimental group showed a higher rate of rising in the self-directed learning ability than the comparison group, and the low academic achievement group showed a higher rising rate of grade than the high academic achievement group. Based on the results of this research, we concluded that the school library-assisted instruction was effective in enhancing middle school students' self-directed learning ability especially for the low academic achievement group.

For teachers to develop new beliefs regarding science teaching and learning, they must undergo a process similar to what they are trying to provide their students. Seventy-one Korean secondary school teachers including 20 earth science teachers have participated in such process. In the four-week long summer workshop hosted by University of Iowa, science teachers were exposed to several activities and lectures wherein they experienced student-centered lessons by playing the roles of both teachers and learners. This study examined the influence of such experience on the teachers’ beliefs about science teaching and learning. Changes in teachers’ beliefs were found in seven question items on the subjects of goals of science learning, the roles of science teachers and students, and classroom practices after workshop participation; it was found that teachers’ beliefs of science learning and teaching shifted from teacher-centered to student-centered. Although this shift does not denote a complete shift from one extreme to the other, it is meaningful to note that teachers’ beliefs after attending the workshop were interpreted to be either anti- or contrary to teacher-centered. One of the possible factors for making such positive changes may have been teamwork or the teachers’ cooperative learning experience.

Recently, in the field of mathematics education, mathematical noticing has been considered as an important element of teacher expertise. The meaning of mathematical noticing is the ability of teachers to notice and interpret significant events among various events that occur in mathematics class. This study attempts to analyze the differences of pre-service secondary teachers' mathematical noticing and confirm the factors that cause the differences between them. To accomplish this, the items on class critiques were established to identify pre-service secondary school teachers' mathematical noticing, and each of 18 pre-service secondary mathematics teachers were required to write a class critique by watching a video in which their micro-teaching was recorded. It was that the teachers' mathematical noticing can be identified by analyzing their critiques in three dimensions such as actor, topic, and stance. As a result, there were differences in mathematical noticing between pre-service secondary mathematical teachers in terms of topic and stance dimensions. The result suggests that teachers' mathematicl noticing can be differentiated by subject matter knowledge, pedagogical content knowledge, curricular knowledge, beliefs, experiences, goals, and practical knowledge.

The purpose of this study was to conduct the instruction for 'Family Life Planning' based on backward design and measured the learners' understanding and satisfaction for testing validity. In short, the result of this study are as follows: In this study, first of all, the students could explain significant concepts, knowledge, and principles for the planning of family life; they could interpret and apply them; they have perspectives on them; they could empathize them; and they could have self-knowledge. The students could also accomplish high achievements for important concepts related to the field of family life planning. In conclusion, this study showed that the developed instruction was very effective for the students to achieve fruitful results, accelerating the learners' persistent understanding. Second, the learners had high satisfaction on the instruction of Family Life Planning based on backward design with the average score of 3.68 out of the perfect score 4. The students could be satisfied with the developed instruction since they could have high interest in the class thanks to diverse learning materials, and they could take an active part in the learning tasks based on group activities and questions. Also they could apply the contents that they learned through task performances to new situation and context. Therefore, this study proved that the developed instruction enhanced the learners' satisfaction on class.

Purposes of this study were to explore the process of experience that science teachers go through when participating in peer coaching meetings to improve teaching ability and to find out factors that affect each process of experience. The data were collected through recording of peer coaching meetings, videotapes of science class, and interviews. All the data were analyzed after transcription. The results of the study showed that even though Teacher K broke the ice and formed consensus among the peers by developing Content Representation (CoRe) at the beginning of the meetings, he became self-defensive rather than receptive of peers' opinions on the recorded class at the discussion session. But as the peer coaching went on, he realized that peer coaching was not about evaluation but rather on improving his teaching ability. In turn, he was able to look at his teaching in a more objective point of view and accepted suggestions from peer coaching discussion. The self-reflection of Teacher K acted as the key factor in the efforts to improve his teaching ability. He sought the concrete alternatives through the class analysis with fellow teachers and showed major changes in his teaching practice from the language habits, pronunciation, and speed of his speech to the interaction with students and class design. However, there was little change in knowledge of curriculum and assessment due to his strong orientation to improve students' grades as an academic high school teacher. Likewise, it was found that while peer coaching exert a strong influence on instructional methods and strategies of Teacher K, his strong orientation to improve students' grades hinders a balanced development of subcomponents of PCK.

This study aimed at finding points of improvement in teaching expertise by analyzing the question patterns that appeared during teaching demonstrations which applied science teaching models prepared by a pre-service biology teacher. The question analysis frame for analyzing question types were categorized largely into the question types of Category 1 (questions in cognitive domain, questions with research function, questions in affective domain), Category 2 (repeated questions, questions for narrowing the range, practice questions), and Category 3 (questions on student activity progress, memory questions, and thinking questions). The results of analyzing question patterns from five different science teaching models revealed a high frequency of questions in the fields of cognition and memory. For the circular learning model, questions from the cognitive field appeared the most often, while, student activity progressive questions in particular were used mostly in the 'preliminary concept introduction stage' of the circular learning model and the 'secondary exploratory stage', in which experiments were conducted, and displayed the characteristics of these stages. The discovery learning model combined the courses of observation, measurement, classification and generalization, but, during teaching demonstrations, memory questions turned up the most, while the portion of inquisitive function questions was low. There were many questions from the inquisitive learning model, and, compared to other learning models, many exploratory function questions turned up during the 'experiment planning stage' and 'experiment stage'. Definitional questions and thought questions for the STS learning model turned up more than other learning models. During the change of concept learning model, the five concepts of students were stimulated and the modification of scientific concepts was very much aided by using many memory questions.

The purpose of this study is to identify the teaching professionalism of the two teachers for secondary science-gifted students in perspective of teaching orientations. Both teachers have been taught biology to secondary science-gifted students for more than six years and they have received in-service training in gifted education. Teachers' orientations were investigated through in-depth interviews and observing lessons. For the data collection, videotapes were recorded during two lessons and two in-depth interviews for each participant were conducted. All recorded data were carefully transcribed and analyzed. Some unique characteristics of teaching were identified from the class instruction of each participant. Both teachers revealed 'Open Inquiry' orientation. This was reflected by their educational goals and beliefs that they should help science-gifted students to grow themselves as scientists by enhancing their inquisitiveness and creative problem solving ability. However, each teacher had shown different teaching orientations such as 'Academic Rigor' and 'Discovery' that seemed to have influence on the level or the range of subject matter covered in the classes. Teachers' science teaching orientations have been changed by their subject of teaching and their experiences in teaching the gifted. In the process, teachers' educational philosophy about gifted education plays an important role in teaching orientation. Based on the ongoing teachers' efforts for enhancing his/her professionalism, the teachers seemed to critically review theoretical knowledge of the science teachers in gifted education through self-reflection on their own teaching methods. When teacher's educational philosophy about gifted education was established and internalized, science teaching orientations in teaching practice seemed to be consistent with his/her goal of teaching.

This study focuses on the 'invention technique and practical experience' unit to observe how the colleague mentoring class has its effect on self-efficacy. For this, we have selected experimental group and comparative group and proceeded the experiment. For five classroom hours of the 'technique of invention and practical experience' unit, each group was assigned different method to do the experiment. The experimental group was applied with the colleague mentoring method and the comparative group was applied with the self study method. To observe the differences of how it effects on one's self-efficacy, the questionnaire was distributed before and after class. Then, it was verified for the meaningful differences between the two groups. To summarize, the results are as follows. First, for self-efficacy experiment, the questionnaire before the experiment showed that there were no differences found between two groups. However, the questionnaire collected after the experiment showed great differences. The group with the colleague mentoring showed more meaningful differences at p<.05 significance level than comparative group. Furthermore, by observing the before and after questionnaire, it was found that both groups showed statistically meaningful differences at p<.05 significance level, but the experimental group showed greater self-efficacy improvements than comparative group. Second, when further examining the self-efficacy, the activity start expectation, activity continuation expectation, activity performance expectation, and experience recovery expectation showed the statistically meaningful differences at p<.05 significance level. According to the above results, it can be stated that the colleague mentoring class has more positive effects on the self-efficacy than self-study class. Summing up, the colleague mentoring class is more effective than self-study for fostering student's self-efficacy.
