The purpose of this study is to analyze the Elementary and Secondary Education Act(ESEA) of the U.S. reauthorized by the Every Student Succeeds Act in 2015 from the viewpoint of the library and information services, and to derive implications for improving the library and information services. For the first time, ESEA includes effective school library programs and school librarians, and links school library programs and school librarians with literacy, digital literacy, books, resources, up-to-date materials, technology, library services and educational services. It provides a financial and institutional base for library and information services in elementary and secondary schools of the US to be more conducted. In addition, school librarians are required to participate in personalized learning experiences, evidence-based assessments, and professional development in the law, so school librarians must provide library and information services to students, staff, and parents in order to improve student achievement and digital literacy. Based on these analyses, this study discussed strengthening access to the school library, specifying the work of the teacher-librarian's library and information services, strengthening collaboration with school members, educational activities based on evidence base, sharing educational effects and developing of library and information curriculum.

The purpose of this study was to survey the secondary science teachers' viewpoints of basic particles conceptions addressed in science course. The first content of this study was to analyze the secondary science teachers conceptions related to basic particles founded on scientific history viewpoints. The second content was to investigate their understanding of relations between atom, element, and molecule concepts. The third content was to search the factors influenced on basic particles conceptions of science teachers. For this study, 96 secondary science teachers were selected. The data of this study were collected through a questionnaire developed for this study and were analysed using the method of constant comparative analysis. The results showed that their viewpoints towards basic particles were similar to each other regardless of their majors and their conceptions belonged to the past viewpoints. The teachers lacked linking understand among basic particles conceptions because they applied different viewpoints on different problems. Most of the teachers were influenced on science textbooks, guidebooks for teachers, and reference books to form confusing viewpoints of basic particles.

The college of education should support pre-service science teachers to develop various abilities as a teacher, in which the teaching ability is the most fundamental one. This study is the result of a longitudinal research project following the processes that pre-service science teachers develop their teaching ability in a college of education. The data gathered include movie clips of seminar presentation, teaching demonstration, secondary school science experiment, and classes in the practicum. In order to analyze the teaching abilities in various context, a framework was developed. The framework consists of 'content,' 'progress,' and 'verbal/nonverbal' with which the movie clips of 5 pre-service science teachers were analyzed. The teaching abilities of pre-service science teachers showed overall development, that include the understanding of learners and curriculum in the 'content,' the time-management and the interaction with learners in the 'progress,' and the nonverbal behavior in the 'verbal/nonverbal.' The implications were discussed on the education in the college of education, such as the increase of teaching opportunities for pre-service science teachers and the support for those opportunities.

The purpose of this paper was to develop and execute self-appraisal test items on secondary science teachers. Test items included 6 sub-fields-subject knowledge, teaching strategies, teaching skills, assessment, laboratory management, and professional development - and 77 items. Using these test items, science teachers were able to evaluate their ability as prescribed by a 5-point Likert scale. Furthermore, teachers were able to comprehend fields showing their highest and lowest scores among the 6 sub-fields. They could then place special attention on the lowest field insuring self-growth as a science teacher. Self-appraisal test items were developed by analyzing related references on teacher evaluation criteria and standards. 220 subjects composed the sample on which these test items were executed. The results of this study were as follows. First, content validity of the test items was 80.8%. The range of sub-field reliabilities was .76 - .86 and the reliability coefficient of the entire test was .95. The range of correlation coefficient between each subfield was .54 - .69 and that of subfields and entire test was .54 - .79. The correlation coefficient between professional development and the whole test was .79, the highest coefficient observed. Second, significant difference was found according to teaching experience. More experienced teachers had higher scores in all 6 sub-fields (p<.05). In addition, a significant difference according to gender was observed in subject knowledge and laboratory management (p<.05); male teachers had higher scores than female teachers. Also, the higher the level of experience, the higher the scores for subject knowledge (p<.05). Lastly, the teacher's major did not result in any significant differences.

For secondary school teachers who attended 'A Social Constructionism Science Teacher Training Program', we analyzed their processes of cognizance change as well as whether they put its results into practice in the field of education, so as to find out the efficacy of the program. 'A Social Constructionism Science Teacher Training Program' consists of three phases based on La main ${\grave{a}}$ la $p{\hat{a}}te$, a French experience-oriented science education program. In its first phase, a study of the philosophy of La main ${\grave{a}}$ la $p{\hat{a}}te$ was made, together with a search for examples of creativity education. In its second and third stages, real education programs were developed for designated themes and free themes, respectively, and then discussions were made. It was a ten-session program, with each session comprising a four-hour sub-program. All activities were both visually and orally recorded, while the participants were asked to write reflective journals for each class. An additional survey and interview were conducted six months later to check if the seven selected secondary school teachers put the results of the program into practice. It was found that changes may be made in the beliefs of teachers with the introduction of theories in teacher indoctrination, but the acquisition of practical knowledge that can be implemented in actual classes may be effectively secured by demonstrations and practice sessions. It was concluded that indoctrination should be conducted to lead participants to the level of practical planning from the level of mere belief so that the theories might actually be put into practice in the education field.

In this study, we analyzed secondary science teachers' needs for mentoring programs improving their professionalism in science-gifted education. A survey was administered to 111 teachers who had experience in teaching science-gifted secondary students in Seoul. Analyses of the results indicated that most teachers needed the mentors' support in science content knowledge, knowledge of beliefs about science-gifted education, knowledge of science-gifted students, knowledge of instructional strategies for science-gifted education, knowledge of curriculum for science-gifted education, knowledge of assessment in science-gifted education, and knowledge of external factors influencing in implementing science-gifted education. Most teachers, especially having the perceptions of lower levels of professionalism, relatively needed more mentors' support in the knowledge of the instructional strategies for science-gifted education and the knowledge of assessment in science-gifted education. Most teachers wanted the mentors' supports for all subcategories of professionalism at the planning stage of the classes, and some did the support for some subcategories at the performance stage and the reflection-evaluation stage of the classes. They also relatively wanted more mentors' support for all subcategories of professionalism through lectures and/or group discussions, some did the support through face-to-face interviews and/or real-time or non real-time online interviews. They variously responded in the suitable ratio of mentors and mentees, and perceived positively the qualities required to mentor as well as the necessary factors for the effective use of mentoring.

The aim of this study was to research the characteristics of science teachers' thinking related to dissolution and diffusion. For this study, five science teachers who majored in chemistry or chemistry education were selected and interviewed. These teachers have been teaching on average for 2$\sim$6 years. From the study, it was discovered that the science teachers didn't recognize the necessity of sorting out diffusion from dissolution. The teachers divided in various mixing phenomena with diverse criteria. The science teachers had difficulty in sorting out diffusion from dissolution based on solubility and Gibbs' energy. The teachers didn't see the linkage between the contents that were divided into chapters, and didn't find omitted contents themselves in the chapters that introduced applicable principles. During the interviews, the teachers felt the need to understand the principles for understanding phenomena. But they did not have the ability to teach these principles after learning about the principles themselves. Therefore, it is necessary to develop teacher education programs, as well as a science curriculum, that helps in linking the knowledge between natural phenomena and principles.

The purpose of the study is to reflect on 'myself' as a teacher educator of college of education in depth and to improve my instruction through self-study with three critical collaborators. 17 pre-service science teachers and I have participated in this study of a teacher educator's course since March 2016 after the preliminary practice in 2015. The video recorded the course for 11 weeks with about 40 hours of lessons. The data source also included teacher educator's reflective journals, lecture evaluations, online boards and so on. Questionnaires were distributed and answered both at the beginning and at the end of the course and pre-service teachers wrote their reflective journals. Four of them were in the focus group interviews. During the course, the weekly group meeting of critical collaborators analyzed the emerging issues based on the lesson clips and teacher educator's reflective journals with discussion for the course innovation. Four phases were revealed in the process and for the purpose of the course such as exploration, conflicts, challenges, and changes. The results showed that first, we identified tensions among the teacher educator's multiple identities as a lecturer, a faculty member, and a researcher. Second, there were differences between goals of teacher educator and pre-service teachers in the course, and this obstructed the success of the course sometimes. Third, these practices led to explore balanced alternative views and interpretations of the problem by critical views and to expand and improve our teaching practice and thinking. In addition, the self-study with critical collaborators helped to bring conflicts and issues below my practice to light for collaborative reflection and it gave a chance to understand ourselves as teacher educators in different ways.
