This study examined what questions posed, and for arranging the matters, what decisions made, what practices put into by elementary preservice teachers during his or her enacting and reflecting mathematics teaching. Analysis of the study focused on the mathematics instructions practiced by four participants in practicum for senior students. Their own questions raised by each one in the instructional designs, performances, and reflections were picked out and categorized by five dimensions of mathematics instruction; the nature of classroom tasks, the role of the teacher, the social culture of the classroom, mathematical tools as learning supports, and equity and accessibility. Their instructional decision-makings and action-takings for answering to these questions were analised.

As a researcher engaged in the mathematical education, mathematics teachers are interested in instructional methods. While it is unlikely that the viewpoints of individual mathematics teachers are reflected in making decisions on instructional purposes and instructional contents, a good many parts of instructional methods on mathematical facts are decided by individual teachers. This means that the role of mathematics teachers is given much weight in the mathematical education. Therefore, the mathematics teachers must not be excluded in all parts of the study of mathematical education. We studied the instructional methods of function concept, a central topic in school mathematics from the following perspectives. First, we examined the characteristics of the three(correspondence-centered, middle, dependence centered) viewpoints about the essence of function concept. And we should that which of them should be the viewpoint of instruction of function concept in school mathematics. Second, we investigated the questions regarding the process of function instruction in school mathematics and presented alternative instruction methods of function concept to solve the questions. Third, we postulated the importance of polynomial function, relating college mathematics in order to present the reason why the polynomial function is importantly treated in functional instruction of school mathematics.

This study investigates the effect of instructional program using Nott & Wellington's" your nature of science profile" to facilitate the understanding about the nature of science for elementary preservice teachers. To do this. this study used posttest only control group design. The students in control group studied the topic by instructional program using textbook and reference book. Experimental group studied by instructional program: (1)evaluating personally one's understanding of the nature of science using Nott and Wellington's "your nature of science profile"; (2)studying the way of understanding the nature of science focusing five dimensions presented in it; (3)knowing other's understanding the nature of science; (4)discussing and evaluating reflectively the various aspect about it. Because the true understanding about the nature of science is not only to know about the method of science but also to know the target of science. We planned to evaluate the effect of instruction by such dichotomous way as evaluating simultaneously the understanding about the method of science and the target of science. Therefore the Questionnaire to evaluate the effect of instruction consisted two pairs of open-ended Questions: first pair is consisted of questions for the representation and judgement of scientific theory, second pair is consisted of questions for components and sources of scientific manipulation of the structure of science. The results of questionnaires by experimental group(n=75) and control group(n=77) are as follows: (1) Analysing responses about first pair of questions in dichotomous way, we identified four different patterns in students' understanding about scientific theory. And the instructional program using Nott & Wellington's "your nature of science profile" is not significantly effective in the distribution of patterns of understanding about scientific theory, but effective in driving out scientifically valid understanding, naturalistic realism, about scientific theory from the students having realistic aspect in representation of scientific theory; (2) Analysing responses about second pair of questions in dichotomous way, we identified five different patterns in students's understanding about structure of science. And the instructional program using Nott & Wellington's "your nature of science profile" is significantly effective in the distribution of patterns of understanding about structure of science, and effective in driving out scientifically valid understanding, dualistic-circular view or dualistic-circular view, about structure of science from the students having dualistic or dualistic aspect in components of structure of science.

Students mostly precede their learning without any direct support of instructor in e-learning and mobile educational environment. Many useful strategies and tools to facilitate self-regulated learning behaviors in e-learning environment have been introduced, yet, the limit has been reached by only suggesting self-regulated strategies with visual information in the most researches. Accordingly, this research is intent to propose the sound design strategies that facilitate learner's self-regulated learning behaviors in mobile learning environment. To achieve the objective of the research, two research questions are presented. First, what are the sound design strategies that facilitate the self -regulated learning behaviors in mobile learning environment?. Second, what are the results of evaluating the developed sound design strategies in terms of facilitating self-regulated learning behaviors?. To solve these research questions, the literature reviews on characteristics of mobile learning, concepts and features of self-regulated learning and sound were done to establish the sound design strategies. Through formative research method targeting instructional designers, sound design strategies were modified and supplemented. The research to validate these was performed and to verify the effect of the derived sound design strategies, the usability test aimed at instructional designer and learners was conducted. The final sound design strategies through this research process were six general design strategies and the sixteen detailed strategies. This research is meaningful because this offers the basic research on sound information design which has been lacking and help upgrade the upper limit of instructional design which mainly focused on visual information in mobile learning environment that shows information in a small screen.

This paper presents a case study in which a lesson was designed and applied to enhance preservice home economics teachers' instructional design competence using the metaverse. For 15 weeks from March 6 to June 14, 14 students enrolled on the course 'Multimedia Home Economics Education' for preservice home economics teachers used the metaverse to engage in problem-based learning to solve instructional design problems in home economics classes. In accordance with the ADDIE design model, in the analysis stage, we assessed preservice home economics teachers' level of knowledge of lessons using the metaverse, and their perceptions of the possibility, necessity, and usefulness of using the metaverse in home economics lessons. In the design and development stage, lesson plans, questions for problem-based learning, assessment tools, and teaching and learning materials were developed. The implementation was conducted in parallel with training on understanding multimedia and the metaverse, and instructional design competence was evaluated through pre- and post-testing and reflection journals. The results revealed that the preservice home economics teachers acquired a good understanding of lessons using the metaverse, learned how to design lessons for self-directed learning by applying the metaverse to their home and classroom, and gained confidence in applying it to their teaching practice or in-service work. It is expected that the results of this study will be used as support materials for prospective and current home economics teachers to design home economics lessons using the metaverse, thereby expanding the horizons of home economics education.

The purpose of this study was to investigate what elementary teachers know about students' science misconceptions and how the teachers plan for and address their students' misconceptions in instruction. The sample included 61 teachers who participated in a teacher training program irrelative to science education. A questionnaire into which Gomez-Zwiep's semi-structured interview questions was transformed was used to examine the teachers' understandings of definition, origin, examples, and so on of science misconceptions, and their instructional strategies for addressing their students' misconceptions before and while instruction. The results showed that many teachers (about 60%) did not have appropriate understanding of students' misconceptions, that the majority of the teachers (about 75%) did not consider misconceptions at all before teaching science lessons, and that almost all the teachers (about 90%) did not know particular strategies specifically designed for misconceptions.
