Using TIMSS survey data, we analyzed whether there were any significant changes in the learning environment of middle school science classes over the last 10 years. Our study selected questions from teachers and school principals' questionnaires and divided them by category: science class, teacher professional development, and school environment. The science class components were subdivided into three categories: science learning activities, evaluation, and homework. Within teacher professional development, the sub-categories included teacher training, collaboration to improve teaching, and teacher evaluation. School environment subdivided into two aspects, these being school characteristics and school system. Our research confirmed that there has been a positive change overall in learning environments. However, most classes are teacher-conducted and also teacher-oriented; the proportion of science investigation activities has declined compared against the prior ten years. Our study show that students do not engage in a range of inquiry-related activities. The questions on tests and examinations involve mostly knowledge application and understanding, although recent methods of evaluation show improvement. As for the science teachers, they participate in many professional development programs but focus on science content, science curriculum, and pedagogy. In addition, teachers do not have many opportunities to participate in the training to integrate information technology into science, science assessment, or improving students' critical thinking or inquiry skills. The teachers are satisfied with their profession, and the shortage of science resources does not seem to affect instruction.

Information ethics, which is closely related to changes that occur in information technology, had been comprised of one unit ever since the curriculum was revised in 2007 from whence 'informatics' was established as the first course, and has remained so even after the curriculum was revised in 2015. The purpose of this study was to analyze the degree of content knowledge required of informatics teachers who will teach information ethics by distinguishing the subject from general ethics, and to grasp the status of information ethics education at graduate schools of education. In order to achieve this, the information ethics questions of the informatics teacher appointment exam from years 2002 to 2015 were analyzed as well as the curriculums of 32 graduate schools of education. The results of the study revealed that, first, questions related to information ethics were included in 10 exams, since the 2004 exam. Second, questions related to dysfunction were mainly addressed from the beginning of administering the exam but since 2010 many items related to copyrights, information security, and various addictions were added. Third, 11(33%) of the 32 graduate schools of education with informatics teacher training provide information ethics courses. This study is meaningful in that it will help to better understand the changes needed to update the information ethics related questions of the informatics teacher appointment exam, and to present a direction for information ethics education at graduate schools of education.

The unprecedented COVID-19 pandemic has disrupted, interrupted, and changed the way we normally prepare our teacher candidates in teacher preparation programs. In this paper, we, two mathematics teacher educators (MTEs), reflect our own experiences in appropriating, transforming, reconstructing, and modifying our pedagogies of teacher education in making a transition from face-to-face to online environment during the COVID-19 pandemic. Using a collaborative self-study, we discussed issues, challenges, changes, opportunities, and innovations of teaching an elementary mathematics methods course in the online environment. Using a constant comparison method, we explored the following three themes: (1) using virtual manipulatives; (2) creating collaborative, interactive, and shared learning experiences for preservice teachers; and (3) making preservice teachers engaged in student thinking. These findings indicated that online teaching requires transformative knowledge for teacher educators. Transferring face-to-face to online is not a simple matter of putting the existing content to online; it should focus on pedagogical improvement in teaching mathematics rather than technology's sake or how it can be repurposed in a new online environment in a way that students' learning is optimized. The findings of this study provide implications for unpacking MTEs' technological pedagogical content knowledge (TPACK), creating collaborative learning experiences for preservice teachers, and designing a collaborative self-study between MTEs engaged in the community of professional learning.

This study aims to examine individual perceptions and lived experiences of the Net generation of student teachers and the previous generation of teachers about their technology use in education. The participants of this study include 106 pre-service teachers and 50 in-service teachers from one teacher education university in Korea. Employing a mixed methodology, we first empirically examined the participants' perceptions toward multiple variables related to technology use in education, namely (a) past ICT experiences in schools, (b) personal computer use, (c) constructivist belief, (d) computer efficacy, (e) attitude toward computer in education, and (f) prospective computer use. In addition, we conducted face-to-face interviews with selected participants for the in-depth investigation of their lived experiences about technology use, beliefs, and attitude. Results indicate that there are significant differences between in-service and pre-service teachers in their prior experiences with technology in schools. However, the pre-service and in-service teachers did not differ significantly in their beliefs, attitude and other technology-related variables, which may indicate the danger of generational determinism in the Net Generation debate. The analysis of interview narratives revealed two major themes about the interplay of one's agency and structural changes in the participants' lived experiences with technology use in education: (a) transition from negative past experiences to opportunities for positive computer use, and (b) attitudes formation and change through apprenticeship experiences and structural influences. In conclusion, this study suggests that the Net Generation debate should move beyond dichotomous or techno-centric thinking. There is a critical need to pay more attention to develop deeper understandings of the fundamental diversity existing within the generation itself. Implications for teacher education are also discussed.

As the recent demand for human resources in science, technology, engineering, and mathematics (STEM), the development of professional STEM teacher is called worldwide. It is becoming a critical need in teacher education in order to educate student teachers, and prepare pre-service and beginning teachers for high quality of teaching competency. To promote the competency for $21^{st}$ century STEM teachers, the epistemology of technological pedagogical content knowledge (TPACK) is currently considered as the essential qualities of knowledge for highly qualified teachers. The aim of this study is explore the effect of case-based learning approach on TPACK competency of pre-service STEM teachers. In order to develop the pre-service teachers' competency regarding effective integration of technologies into teaching specific content areas, a series of innovative case study teaching in science and mathematics was presented to 43 participants of pre-service physics, chemistry, biology, mathematics, and computer teachers during a course of information and communication technology (ICT) in Education at Khon Kaen University, Thailand. After finishing a case presentation, the pre-service teachers were encouraged into a forum of critical open discussion by considering the potential impact of the case and the TPACK framework. They were investigated instructional design competency of using ICT tools into student learning process and their personal beliefs about ICT in educational process both before and after. The participant's reactions and learning was evaluated by using a self-reported questionnaire and an implementation log of content-specific learning process design, respectively. Results showed a change of their beliefs and the transformation of their TPACK competency in STEM teaching. In an effort to better serve the needs of high quality STEM teachers, the results of this study illustrated that the competency of TPACK could be particularly considered as a core attributes for future STEM teachers. By the way, case-based learning approach can play an effective part in preparing and professing the TPACK competency for STEM teachers.

In this paper, we analyze the performance of the recently introduced Hint-knowledge distillation (KD) training approach based on the teacher-student framework for knowledge distillation and knowledge transfer. As a deep neural network (DNN) considered in this paper, the deep residual network (ResNet), which is currently regarded as the latest DNN, is used for the teacher-student framework. Therefore, when implementing the Hint-KD training, we investigate the impact on the weight of KD information based on the soften factor in terms of classification accuracy using the widely used open deep learning frameworks, Caffe. As a results, it can be seen that the recognition accuracy of the student model is improved when the fixed value of the KD information is maintained rather than the gradual decrease of the KD information during training.

This study aimed to design and apply the technological pedagogical and content knowledge(TPACK) model to pre-service education program, and to analyze its results for attending student's questionnaire. At first, a lecture that designed to elevate one's technological knowledge was studied and implemented. To perform this study, TPACK survey instruments were distributed to pre-service teacher group A who took the designed lecture and group B who took ordinary ICT literacy lecture. The results showed that TK, TCK, TPK, and TPACK improved significantly in group A, and significant positive corelation shows among 7 subcategories of TPACK. Based on the result of this study, we suggested that pre-service teacher education should consider the combination of pre-service education program and technology knowledge in TPACK model.

The purpose of the study is to examine the relationship between teacher enthusiasm, support for teacher autonomy, support for relationship with peers, and grit for preliminary high school students. This will be able to provide useful information for effective instruction and search for various teaching-learning methods in the physical education field. It was selected based on convenience sampling and judgmental sampling, focusing on those who participate in physical education classes for middle school students. Of the 200 respondents to the questionnaire, the study was conducted through 182 copies, excluding 18 questionnaires that were judged to be unreliable or responded collectively. When looking at the effects of physical education teachers' passion on autonomy support and relationship support, the hypothesis was adopted as it was found to have a statistically significant effect. Relationship support appeared to have a statistically significant effect on grit, so the hypothesis was adopted. However, support for autonomy was rejected as it did not appear to have a statistically significant effect on grit.
