This study investigated the contents and methods of science education classes based on the largely constructivist approach of pre-service early childhood teachers. The subjects of this study consisted of 8 junior students from the Early Childhood department and for reference data, reflective journals, interviews, activity planning sheets, recordings of trial lessons, and lesson analysis were used. The results of this study were as follows. First, changes in key points and contents for children science education were found, and reflective journals, interviews, activity planning sheets, recording of trial lessons, and lesson analysis clearly supported these results. Second, the actual changes in the constructivist approach to children's science education had a great impact upon the individual characters of the pre-service early childhood teachers. However, with the study period being limited to only one semester, it was found that the potential of this study to lead to any practical changes was simlilarly limited.

The purpose of this study was to examine the effect of the CoRe-based density unit class on conceptual formation and on learner satisfaction with the class. For this study, two hundred and forty 8th grade students were chosen from six classes. The students were divided into two groups: an experimental group, which received a CoRe-based density unit lesson, and a control group, which was taught based on traditional teaching method. The CoRe-based density unit classes consisted of 4 periods based on the analysis of the previous studies on CoRe about density. The results showed the meaningful significant difference between the CoRe-based classes and the classes based on traditional teaching method both in the posttest on the extent of the conceptual formation on the density and in the retention test. The difference suggests that the lesson with CoRe is based on the consideration of the difficulties and limitations students face in various fields such as the students themselves, teachers, learning environment, evaluation, etc. during their learning process and even in the types of preconception they have, and the CoRe-based lesson is centered around the best teaching strategies to solve such difficulties. As a result of the analysis on the experimental group's class satisfaction, it is revealed that the students with a high level of attitudes related science or with a high level of science achievement showed especially high satisfaction in their learning. Analysis of questionnaire survey showed that the students in the experimental group got the opportunity through CoRe-based lesson to stretch their thoughts and ideas in a free way and preferred a teaching method which didn't just show the concept, but allowed them to find it for themselves or which let them predict the solution and then confirm the result on their own and a lesson which encouraged their active participation.

This study developed and proposed a lesson plan for the area of “Human development and family relationship”in secondary home economics curriculum. In current educational practice in secondary home economics curriculum, the employed goal and the nature of home economics are neither stated specifically nor closely interrelated. This problem has led us not being able to achieve pursuing goal of home economics education and to employ appropriate teaching methods. In view of this situation, the purpose of this study was to propose a lesson plan reflecting the contents and teaching methods to overcome difficulties and inefficiency in the current practice of secondary home economics education. The theoretical background of the lesson plan was based on the Marjorie M. Brown’s philosophy of home economics which can be summerized as follows: 1. The goal of home economics is to help individuals and families to become autonomous in their own family life and to be more capable of interacting with others in behalf of well-being of the family and of social evolution toward a free society. 2. The characteristics of home economics is conceptualized as practical science and personal service profession. 3. the nature of problems which home economics should deal with is perennial and practial. 4. Practial reasoning composed of historical understanding, critical action, and reflective thinking is appropriate for the previously mentioned goal and characteristics of home economics and for dealing with perennial practial problems. The lesson plan was proposed for one of perennial problem, “How should we understand, create, and maintain our family culture\ulcorner”by employing practial reasoning and teaching models such as “role play”and “classroom meeting.”

Purpose: The aim of this study was to evaluate the effect of student question-centered lessons for bi-directional faculty-student communication. Methods: This study performed one-group pretest-posttest design; participants were university students majoring in health science (nursing 58, physical therapy 45) in city C. Data was collected and the program was conducted from March 3 to June 14, 2014. Measurements employed were the ARCS model of motivational design, self-assertiveness, learning satisfaction, and interpersonal relationship. Data was analyzed through frequency statistics, descriptive statistics, and repeated measurement of one-way analysis of variance with the SPSS 19.0 program. Results: In this student question-centered lesson participants exhibited significant enhanced satisfaction in terms of learning motivation, learning satisfaction, self-assertiveness, behavioral assertiveness, general assertiveness, and sensibility regarding interpersonal relationships. Conclusion: The results suggest that student question-centered lessons are applicable to a variety of subjects. Also, for comparative purposes, a faculty-centered lesson will be undertaken.

This study explores how a teacher copes with anomalous situation in primary practical science lesson and what factors affect teacher's strategy to cope with anomalous situations. The method of auto-ethnography was used in order to capture the inner experience of the individual teacher. For this, one of the researchers participated in this study as the teacher participant. Two science lessons that the researcher taught as a teacher were observed by a co-author and video-recorded. However, only one lesson which the teacher experienced the anomalous situation was analyzed. After the lesson, self-interviews were conducted with the co-author. Also the researcher wrote four reflective journals about anomalous situations that she experienced. What has emerged in this study is that anomalous situations were experienced by the teacher while students were doing practical work and while students were presenting their results of practical work. As each anomalous situation was experienced in different contexts, the strategies that the teacher used were different and were affected not only by the personal epistemological belief but also by the socio-cultural context that the teacher was surrounded by. This study has implications to help teachers who have difficulties in coping with anomalous situations.

The purpose of this study was to analyze of how the elementary school teachers lead their classes of a science laboratory instruction and an engineering laboratory instruction in a science subject class. For this study, science laboratory and engineering laboratory lessons were selected and for each science and engineering laboratory lesson, five elementary school teachers were video-recorded of their lessons. The science and engineering laboratory lessons were analyzed by utilizing processes of the science model and the engineering model based on Schauble et al. (1991). The results of these studies are as follows: In science laboratory instruction, some participants didn't distinguish the difference between the science laboratory goal and the engineering laboratory goal. All of participants used search and end strategy of engineering laboratory for science laboratory lesson. In engineering laboratory instruction, all of participants guided to students engineering laboratory goal and used inferences and search strategy of engineering laboratory. However they didn't use the trial and error strategy or redesign which can be an essential element in engineering and design process. Educational implications are discussed.

The purpose of this study was to develop a spider inquiry program for elementary school students based on the scientific-knowledge generating model. For the purposes of this study, we selected three species of snider (e.g. Pardosa astrigera, Argiope bruennichii, Nephila clavata) which were easily found in a school garden by elementary school students. The spider inquiry program was based on a model of the process of scientific-knowledge generation, and consisted of two sections: for students and teachers. The students' program was designed to generate scientific-knowledge, whilst the teachers' program was designed to guide the inquiry smoothly even in the case of teachers who lack experience in inquiry activities or possess limited subject knowledge on spiders. As a result, this program was found to have an influence on generating the scientific-knowledge of elementary students and the results further suggest that it may be helpful to teachers conducting an inquiry activity. Additionally, this program could be used as a selective activity lesson such as a science inquiry lesson, or as a biology inquiry class, as a weekend life experience study or as an activity on a science camp.

In order to measure students' fun and the effectiveness of teaching materials related to computer science theory, this paper conducted an experiment lesson against middle school students using Timbel's 'Unplugged' textbook. A preliminary test was conducted and it revealed that the students' understanding of computer science theory was extremely poor. The learner's fun for the experimental lesson showed the positive reaction in the viewpoint of expectation, engagement, endurability. In post-test after one month, the students were able to recall most of the materials covered during the experiment lesson. In addition, they all showed sign of good understanding. In conclusion, Timbel's textbook proved effective in increasing students' fun and learning ability related to computer science theory. Furthermore, this paper would like to suggest a new type of Informatics science teaching material that might be essential for future computer science education.

This study investigated the characteristics of pre-service elementary teachers' TPACK in science lesson planning using VR/AR content based on epistemic network analysis (ENA). Seven TPACK coding elements were derived inductively based on the existing TPACK framework. Then, the pre-service elementary teachers' discourse in science lesson planning was coded according to the seven TPACK coding elements and analyzed using the ENA Web Tool. The discourses of the two groups were analyzed and compared, and the differences between the two groups, which the researchers analyzed qualitatively, were clearly shown on the ENA graph. Based on these findings, the researchers argued that the ENA method is a useful research tool for analyzing the complex interactions of technology knowledge (TK), content knowledge (CK), and pedagogical knowledge (PK), which is different from previous TPACK research. Also, the researchers discussed the implications for the TPACK competency development of pre-service teachers by comparing the characteristics of the two groups' discourse.
