This study was to understand the components that influence preservice secondary teachers' conceptions about 'seasonal changes' We selected 74 university science education students among whom 23 were in the second, 23 in the third, and 28 in the fourth year. The data collected from the paper-pencil test and individual interview with students. The results of this study show that the students had considerable apparent alternative conceptions, and that the 'distance theory' had most important effects on their alternative conceptions. It can be said that preservice secondary teachers' initial models of the seasonal change have their origin in their belief sets (specific theory) related to 'seasonal change', on the basis of which they can interpret their observations and cultural information with the constraints of a naive frame-work of physics. The structures and possible sources of their alternative conceptions for overcoming these alternative conceptions were also discussed. Implications for preservice science teacher education related to the results were discussed.

In learning environment at mathematics education, prove and refute are essential abilities to demonstrate whether and why a statement is true or false. Learning proofs and counter examples within the domain of limit of sequence is important because preservice teacher encounter limit of sequence in many mathematics courses. Recently, a number of studies have showed evidence that pre service and students have problem with mathematical proofs but many research studies have focused on abilities to produce proofs and counter examples in domain of limit of sequence. The aim of this study is to contribute to research on preservice teachers' productions of proofs and counter examples, as participants showed difficulty in writing these proposition. More importantly, the analysis provides insight and understanding into the design of curriculum and instruction that may improve preservice teachers' learning in mathematics courses.

This study systematically examined the influence of preservice teachers' self-efficacy and AI anxiety, on the intention to use AI programs 'knock-knock! mathematics expedition' in mathematics lessons based on a technology acceptance model. The research model was established with variables including self-efficacy, AI anxiety, perceived ease of use, perceived usefulness, and intention of use from 254 pre-service teachers. The structural relationships and direct and indirect effects between these variables were examined through structural equation modeling. The results indicated that self-efficacy significantly affected perceived ease of use, perceived usefulness, and intention to use. In contrast, AI anxiety did not significantly influence perceived ease of use and perceived usefulness. Perceived ease of use significantly affected perceived usefulness and intention to use and perceived usefulness significantly affected intention to use. The findings offer insights and strategies for encouraging the use of 'knock-knock! mathematics expedition' by preservice teachers in mathematics lessons.

The purpose of this study was to investigate the graph interpretation ability and perception of high school students and preservice secondary teachers in Earth science. We developed two different instruments; one was a graph interpretation ability inventory that consists of 9 graph types with 18 items, and the other one is two questionnaires to explore the participants' perception about Earth science-related graph. The results of this study are as follows: High school students and preservice secondary teachers demonstrated their remarkable ability in interpreting a line graph, but showed their limited ability with the graph of overlapped and directional change, which means the graph interpretation ability was affected by a graph type; two groups participated in this study revealed a considerable difference in the graph interpretation ability depending on the grade level; preservice teachers were superior to high school students in discriminating two graphs, the representation method, which are different with the same topic; and many participants in both groups considered that the property of Earth science graph was considerably different from that of other science subjects, especially in directional change graph, scatter graph, contour map, and domain graph. The results suggest that the effective graph instruction strategies be developed in Earth science learning.

The purpose of this study is to cultivate the attitudes of preservice early childhood teacher's commitment by analyzing the effects of education practicum, teacher efficacy, and emotional intelligence on teacher's education commitment and analyzing the relationship between them. To this purpose, a total of 150 questionnaires were distributed to 75 preservice early childhood teachers of the metropolitan area from November 1, 2018 to March 2019. The results of the study were as follows: First, education commitment of preservice early childhood teachers was positively correlated with teachers' efficacy, emotional intelligence, and education practicum experiences. Second, education commitment increased when the emotional intelligence increased before the education practicum experience, and education commitment increased when the teacher's efficacy increased after education practicum experience. In light of these, It suggests that programs or content education that can strengthen emotional intelligence are effective before education practicum. and that programs or content education that enhance teacher efficacy capacity are more effective after education practicum.

The goal of this study was to investigate how hypotheses were elaborated after their initial appearances in the context of scientific problem solving. Data were collected from a class in which preservice elementary school teachers in groups carried out abductive inquiry of earth science. The analysis revealed two major processes of hypothesis elaboration: theory-driven and evidence-driven. The theory-driven process was in turn distinguished into two kinds of subprocesses: one is in pursuit of internal coherence and the other external coherence. The evidencedriven elaboration also had two subprocesses, which were triggered by direct evidence and indirect or analogical evidence, respectively. In addition, hypotheses were more often than not modified by a wrong theory or evidence whether it was driven by a theory or evidence. Implications for science education and related research were discussed.

While great efforts are being exerted on the reform of teacher training to provide integrated use of ICT in a teaching-learning process with educational informatization, it is still indicated that a teachers' training school fails to prepare leachers for incorporating information Communication and Technology (ICT) properly into an instructional process. Based on this awareness, this study aims at examining and analyzing the ability level of In utilization training for preservice teachers and thus at providing basic data to perform ICT utilization teaching-learning according to the seventh curriculum in a school. For this purpose, a survey was conducted with preservice teachers (seniors) in a college of education, Kongju National University and the collected data were analyzed using a Statistical Package for the Social Science (SPSS) 12.0 program.

This qualitative study explores how volunteering to help in early childhood education is conceptualized from the perspectives of three parties involved; university students, university professors, and principals as well as teachers, and children‘s mothers from a local daycare center and a kindergarten. Data was collected through journals, interviews, and several other artifacts, such as student portfolios, and letters from mothers. Findings were as follows: firstly, preservice early childhood teachers defined voluntary activity in early childhood education as a service that requires motivation and responsibility, and as an activity that helps to establish their identities as teachers. Secondly, university professors constructed the system for service learning activities and helped preservice early childhood teachers’ change the view from volunteering activity to volunteering learning. Thirdly, the local community referred to these activities in terms of the partnerships made for children‘s education and the possibility of cooperative childcare. The findings of this study describe the perspectives of parties involved and may be helpful in planning and executing specialized volunteer projects as well as in understanding volunteer behavior.
