This study examined inservice elementary teachers' thoughts on the development of educational apps by preservice elementary teachers and implications for TPACK education for preservice elementary teachers. A case study was conducted in which preservice elementary teachers developed a science education app, and the three teachers were surveyed for their thoughts regarding this. The results regarding the characteristics of the developed app by preservice teachers were as follows. First, "inquiry" had the highest value among educational goals intended by the preservice teachers. In addition, the scores for tool-type apps and apps in which interaction between learners and instructors occurs were relatively high. Second, most of the preservice teachers developed apps to meet curriculum goals, but their apps showed low-level characteristics in terms of the constructive and cooperative dimensions. The results of the analysis of the thinking of elementary school teachers regarding the education development apps are as follows. First, elementary school teachers assigned the lowest scores to the effectiveness of the apps, and to this problem, the achievement standard with respect to the curriculum and the evaluation and modification activities fir the apps were proposed. Second, the teachers indicated that it would be appropriate to provide the experience of making apps to directly improve the TPACK of preservice teachers. Third, the respondents thought that preservice teachers should develop block coding literacy to create apps using App Inventor. Fourth, the teachers considered it necessary to emphasize simulated instructions, as well as the experience of collecting and handling data through apps to improve preservice teachers' TPACK app development for educational use.

This study was to investigate what pre-service teachers pay attention to when designing science lessons. As a result of analyzing the responses of pre-service teachers, it is analyzed that pre-service teachers are designing science lessons with emphasis on science inquiry, considering students' interest, level, and treatment of misconceptions, and closely related to daily life. In particular, it was found that elementary school pre-service teachers made a lot of comments on science class design that emphasizes experimentation and inquiry, so it was found that emphasizing inquiry was recognized as an important point in science lesson design. It is very positive that pre-service teachers recognize important aspects of science education, such as emphasizing inquiry. In addition, it is suggested that the opportunities for class design and demonstration through collaboration with teachers and colleagues should be increased for pre-service teachers' professional development of teachers.

This study aimed to compare academic passion for science pedagogical content knowledge (PCK) between pre-service and in-service elementary teachers. In addition, a comparison between passion for science subject matter knowledge and passion for science pedagogical knowledge was made for each group of teachers. Participants comprised 182 students from colleges of education and 161 in-service teachers. We analyzed between- and within-subject comparisons for each component of academic passion for science PCK. The results of this study are as follows: First, between-subject comparison demonstrated that, in academic passion for science subject matter knowledge, in-service teachers had a higher passion for "liking" and "importance" than pre-service teachers, whereas pre-service teachers had a higher passion for "time/energy investment" than in-service teachers. In academic passion for science pedagogical knowledge, pre-service teachers had a higher passion for "time/energy investment" than in-service teachers. Second, the within-subject comparison showed that only "harmonious passion" was higher for science pedagogical knowledge than science subject matter knowledge in pre-service teachers. However, "liking", "importance", "time/energy investment", and "obsessive passion" were higher for science subject matter knowledge than science pedagogical knowledge in in-service teachers. The educational implications are discussed.

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.

This study aimed to investigate the effects of portfolio application on pre-service science teachers' reflective thinking. For the purpose, we used narrative inquiry on pre-service science teachers' portfolios. We also analyzed the dimensions and levels of pre-service science teachers' reflective thinking. Analysis results showed that the pre-service science teachers' reflective thinking was mostly centered on focus at the beginning of semester. In addition, they exhibited routine and technical levels of reflective thinking. Analysis of pre-service science teachers' reflective thinking showed it as gradually extending to the dimension of inquiry and dimension of change by the end of semester. Here, the level of reflective thinking was higher at the dialogic level and transformative level. Pre-service science teachers showed that they had difficulties in making portfolios. However, they answered positively about application of portfolios. The results of this study suggest that there is a need to actively introduce portfolio assessment in teacher education courses in order to increase the reflective thinking of pre-service science teachers.

This study focused on the practical research needed to improve elementary school science lesson plans. Specifically, a video clip-based pedagogical reasoning activity that included elementary student misconceptions was presented and the influences of this activity on preservice teachers' science lesson planning were assessed. First, the eight preservice teacher participants were asked to write a lesson plan for a dissolution and solution unit, after which a first semi-structured interview was conducted. Then, the participants participated in a video clip-based pedagogical reasoning activity. Based on the activity results, the participants revised their previously planned lessons, and second semi-structured interviews were conducted. The data from the preservice teachers' lesson plans and interview transcripts were analyzed using a constant comparative method to investigate the lesson plan changes. It was found that after the video clip-based pedagogical reasoning activity, the preservice teacher tightened the activity or changed the material to understand the students' thinking processes. In addition, they supplemented their goals and assessment criteria to accommodate the diverse students' thinking. Some also specified motivational strategies that considered student interests, motivation, and possible misconceptions. However, some preservice teachers still set goals that did not sufficiently account for student misconceptions and some planned the student assessments based only on the learning goals rather than the students' thinking. The few preservice teachers were able to develop motivational strategies that considered interest, motivation, and misconceptions. The preservice teachers claimed that they had difficulty predicting the misconceptions and connecting these to the lesson content. Discussions were then held to assist the preservice teachers to consider possible student misconceptions when planning their lessons.

The purpose of this study is to investigate earth science pre-service teachers' perceptions and educational utilization of geoparks. It is intended to provide implications of geopark education in the current curriculum and effective geopark education. Education using geoparks has the effect of helping students cultivate inquiry and learning skills, enhancing students' participation in classes. To provide education with these results, it is necessary to deliver meanings of the geopark education to of earth science pre-service teachers who will educate future generations. However, despite the advantages and needs of geopark education, earth science pre-service teachers lack an understanding of geoparks. In this study, 56 pre-service teachers enrolled in earth science education at a university in Gyeongsangbuk-do were investigated for: their perception levels of geoparks, experience, necessity, and learning method of geopark education. As a result, earth science pre-service teachers were well aware of the geoparks, but they lacked knowledge of domestic and global geoparks, confirming the need for geopark education. Currently, the degree of geopark education in the secondary curriculum is insufficient, and earth science pre-service teachers feel the need for it. However, since the understanding of geopark is lacking, support for geopark education is needed. Earth science pre-service teachers being positive about the need for geopark education, it is expected that geopark education will be active in the field of earth science, social, and comparison education when they become teachers in the future.

The purpose of this study is to develop the questionnaire on pre-service elementary teachers' recognition of self-understanding and change capacity for science education and to investigate their recognitions with it. At the beginning of the study, we made a tool to investigate the self-understanding and change capacity of pre-service elementary teachers through literature review and discussions. The former half of the questionnaire was related to self-understanding with factors such as 'self-concept clarity,' 'career identity' and 'self-efficacy:' 'self-understanding as a pre-service elementary teacher' (12 items) and 'self-understanding as a pre-service elementary science teacher' (12 items). Its latter half was about the change capacity with factors such as 'change sensitivity,' 'goal consciousness,' 'collaboration,' 'reflection,' and 'mastery.' It consisted of three parts: 'general change capacity,' 'change capacity as a pre-service elementary teacher' and 'change capacity as a pre-service elementary science teacher' with 17 items, respectively. With this tool, we surveyed 153 pre-service elementary teachers. The results are as follows: First, pre-service elementary teachers have a positive recognition about self-understanding and change capacity, but the recognition of self-understanding and change capacity as pre-service elementary science teachers were relatively less positive. Second, factors of self-understanding and change capacity as pre-service elementary science teachers have a significant correlation with each other. Especially, there was a high correlation between 'self-efficacy' of self-understanding and 'goal consciousness' and 'mastery' of change capacity. Based on these results, some implications for self-understanding and change capacity related to science education were discussed.

This study aims to describe, explain, and understand the process of coteaching instruction in which two pre-service science teachers plan, perform, and reflect the instruction in a university lecture. Pre-service science teachers exchanged their perspectives on teaching, selected the learning model and the science content to teach, and prepared the teaching material together. They performed the coteaching using the lecture room effectively and exchanging the role of leading the instruction. The professor and other pre-service science teachers participated to the coteaching instruction directly or indirectly with the role of students or lesson critics, and shared the evaluation and reflection on the instruction. We discussed the meaning and implication of the coteaching instruction on the secondary education field, the science teacher education, and the science education.
