To secure the validity and reliability of the SET, the authors have applied Rest`s Four Components Model (FCM). To develop the SET, authors have conducted the following procedures: analysis of the Korean Youth Moral Test (Kim & Lee, 2012), alteration of the KYMT; and development of the SET. Rest`s FCM is consisted of moral sensitivity, moral judgment, moral motivation, and moral character. The SET is consisted of ethical sensitivity, ethical judgment, ethical motivation, and ethical character with each factor having its own elements. To secure the validity and reliability of SET, authors requested a validity assessment from five experts (two evaluators are science education experts, two others are ethics education experts, and one evaluator is a scientist), and surveyed 599 elementary school students. As a result, SET proved high levels of validity and reliability.","PeriodicalId":107400,"journal":{"name":"Journal of the Korean Association for Research in Science Education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123978087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then the next semester, through the science methods course II, the preservice teachers had a chance of the simulated teaching by adopting NOS teaching and learning activities in the context of the secondary biology context. The preservice teachers, further, reflected on their NOS teaching. The results showed that the preservice teachers constructed the NOS pedagogical content knowledge. They significantly improved their views of NOS and its teaching(p.05). The preservice teachers mentioned the difficulties of teaching NOS in the secondary biology context, and further suggested effective NOS teaching methods in their reflective journals.","PeriodicalId":107400,"journal":{"name":"Journal of the Korean Association for Research in Science Education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116667282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Target textbooks among those developed for the 2009 revised elementary school science textbooks are the first and second semester of the 4th-grade. Methods used include analysis on the roles of character-containing questions using character role analysis whose illustration analysis frame is more supplemented/adjusted than those used in the foregoing studies, analysis on character-containing questions using the existing analysis frame, analysis/survey on good cases and cases needing supplement through consultation with a science education expert, two teachers, etc. The result shows that among types of character roles, motivation and material provision are more used than experiment guide, experiment, and observation results. Result of analyzing in-textbook characters by field shows that life sphere is more used than free exploration, energy, material, and earth. Result of analyzing question types shows the order of expanding, anticipatory, transferable and personal questions and there were no reminiscent and evaluative questions. Based on the result of this study, indications on how to use in-science textbook characters more efficiently and developmentally are needed.","PeriodicalId":107400,"journal":{"name":"Journal of the Korean Association for Research in Science Education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126166641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results are as follows. First, the students have various experiences. They acquire scientific knowledge and inquiry skills by conducting in-depth experiments, visiting several places, and interviewing experts. They have some experience in writing experiment journals to record the inquiry process in their own language, and presenting their results in public. Second, the students suffer several difficulties while preparing for the science fair. They have some difficulties when the results were not consistent with the hypothesis, or they had to repeat the experiment over and over. They feel burdened in writing the experiment journal. They had a few time to meet friends or for hobbies. Third, the students improve scientific attitude through the science fair, and they receive a positive effect on the affective side. They developed scientific interest, curiosity, cooperation, etc. And they also gained a sense of accomplishment, confidence, friendship, good relationship with teachers, career interest, etc. This study finds out that students participating in the science fair have a lot of experience that cannot be done easily in a normal science class. Even though students confront some difficulties in the inquiry process, they make good progression and feel accomplished. So the science fair is valuable experience for them.","PeriodicalId":107400,"journal":{"name":"Journal of the Korean Association for Research in Science Education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121247061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To do this, the authors investigated middle school students` motivational belief about learning science, self-directed learning ability, and conceptual understanding of matter change using measurement tools based on previous studies, and then analysed the casual relationship between three variables using PLS structural equation model. As a result, three latent variables in this study could be evaluated as appropriated in reliability and validity. And also, self-directed learning ability could affect both the motivational belief and conceptual understanding, while motivational belief could affect only self-directed learning ability but not conceptual understanding. Through this study the authors confirmed that in the context of science learning self-directed learning ability can directly affect conceptual understanding but motivational belief can affect indirectly. This study is significant in that the causal relationship between different variables in science learning could be confirmed in a quantitate manner, and also in that it can suggest PLS structural equation method as a new research methodology in science education research area.","PeriodicalId":107400,"journal":{"name":"Journal of the Korean Association for Research in Science Education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128370662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this study, the 2015 revised 'Integrated Science' curriculum and 11 types of pre-service science teachers' learning materials related to physics, chemistry, biological science, and earth science were selected. The results were as follows. Most of the learning content presented in the 2015 revised 'Integrated Science' curriculum had integrated two or more science fields. Also, almost all learning content presented in the 2015 revised 'Integrated Science' curriculum were included in pre-service science teachers' education content, with educational content for chemistry introduced at the highest rate. The textbooks for pre-service science teachers had the most learning contents of 'Energy and Environment' domain of 'Integrated Science' for high school students. Accordingly, these results suggest that 'integrated science materials' should be developed for proper the curriculum implementation.
