The objective of this study was to conduct a 'Theory of Home Economics Education' class using online problem-based learning(PBL) for prospective home economics(HE) teachers. The aim was to enable teachers to analyze the learning experience in the classroom, and to prepare operational strategies for online PBL on this basis. In order to achieve this, online PBL was applied to 31 students participating in the 'Theory of Home Economics Education' at the Department of HE in a university in Seoul, and the results were collected from the learning process. This also involved a reflective journal, a survey on the learning experience and the impacts was conducted. Moreover, analysis was undertaken on the learning activities, learning difficulties, and improvements. The main research results are as follows. Firstly, students accessed Webex, an online video conferencing program, and performed two PBL tasks: 'Making Home Economics Promotion Materials' and 'Presenting Teaching Strategies to Improve Learner's Immersion in Online Classes'. Secondly, learners established their own identity of HE learned about the HE class plans themselves. They also encountered realistic experience as HE teachers and learned communication and collaboration skills. Furthermore, they acquired creative problem-solving and self-directed learning ability, community consciousness, as well as the attitude of consideration and respect. Thirdly, students lacked knowledge of learning content and encountered difficulty in solving data research, analysis processes, and unstructured problems. They were affected by a lack of time and encountered problem in communicating with other team members in an online environment. As an improvement in online class operation, it was considrered necessary to reduce the learning burden by securing time and reducing the number of assignments, as well as to explain active interaction with instructors and PBL.

Prospective high school students and science teachers' perceptions of 'advanced material', which was first introduced in the science textbooks of the 2009 revised curriculum, were surveyed. One thousand four hundred and ninety nine students and 123 teachers from Seoul, Incheon, and the Kyeonggi areas participated in this survey. The results are as follows. First, the attitude of students and teachers towards 'advanced material' was positive, but their interests in 'advanced material' was low. Also, some teachers mentioned that 'advanced material' was one of the difficult subjects to teach. Second, the perception of 'advanced material' was relatively low for both students and teachers. Both of them had heard of 'advanced material' through various routes, however not many of them thought that they knew what 'advanced material' was exactly. Also there were some teachers who didn't understand the detailed information of 'advanced material'. Third, both students and teachers agreed that 'advanced material' was worthwhile to learn and teach. However, each party had their own desire of 'what to learn', 'what to teach', 'how to learn' and 'how to teach'. Based on the results, some suggestions were made for effective teaching of this new subject.

The sense of happiness of early childhood teachers has a great influence not only on teaching but also on infants. The purpose of this research is to investigate how prospective pre-service teachers' sense of happiness influence their teacher professionalism and teacher efficacy. The subjects were 264 pre-service teachers' in Gwangju metropolitan city and Jeollanamdo province. Statistical analysis of this study was done by Pearson's correlation coefficient and multiple regression analysis using SPSS WIN 22.0 program. The results of this study were as follows. First, there were significant positive relationships among the sense of happiness on teacher professionalism and teacher efficacy. There was a significant positive correlation between external happiness, inner happiness, and self-regulated happiness, which are indicating that there is a meaningful correlation between pre-service teachers' sense of happiness, teacher professionalism and teacher efficacy. Second, the sense of happiness was an important factor for predicting the teacher professionalism and teacher efficacy of pre-service early childhood teachers. The results of this study show that the pre - service teacher 's sense of happiness is a predictor variable that positively affects teacher professionalism and teacher efficacy. In conclusion, It is meaningful in seeking ways to improve teacher education by enhancing the euphoria of prospective pre-service teachers during school life and strengthening positive aspects of the educational contents and processes of the institutions that train infant teachers.

Objective: The purpose of this study was to explore the structural relationships among parents' and teachers' autonomy support, children's basic psychological needs, and children's participation in decision-making. Methods: The participants were 687 elementary school students (5th and 6th grades) in Seoul and Gyeonggi-do. The data were analyzed using SEM. Results: First, parents' and teachers' autonomy support had a direct effect on children's participation in decision-making. Second, parents' and teachers' autonomy support had an indirect effect on children's participation in decision-making through the children's basic psychological needs. Third, children's basic psychological needs mediated the effects of parents' and teachers's autonomy support and children's participation in decision-making. Conclusion: The findings suggest the importance of the mediating effect of children's basic psychological needs, between parents' and teachers' autonomy support and children's participation in decision-making. The findings can be used as an important basis for prospective research and practices for improving children's participation in decision-making.

This study explored preservice secondary mathematics teachers' mathematical knowledge for teaching [MKT]. In order to measure preservice teachers' MKT, we developed items according to Ball, Thames & Phelps (2008)'s domains and conducted to 53 preservice teachers. Also, we interviewed 1 preservice teacher with the items and a set of interview questions. The findings from the data analysis suggested as follows: a) overall, the preservice teachers scored average 30.2 out of 100; b) the preservice teachers appeared to be unable to explain students' difficulties in learning a specific mathematical idea and how they would respond to and resolve such difficulties.

Mathematically deductive reasoning skill is one of the major learning objectives stated in senior secondary curriculum (CDC & HKEAA, 2007, page 15). Ironically, student performance during routine assessments on geometric reasoning, such as proving geometric propositions and justifying geometric properties, is far below teacher expectations. One might argue that this is caused by teachers' lack of relevant subject content knowledge. However, recent research findings have revealed that teachers' knowledge of teaching (e.g., Ball et al., 2009) and their deductive reasoning skills also play a crucial role in student learning. Prior to a comprehensive investigation on teacher competency, we use a case study to investigate teachers' knowledge competency on how to teach their students to mathematically argue that, for example, two triangles are congruent. Deductive reasoning skill is essential to geometry. The initial findings indicate that both subject and pedagogical content knowledge are essential for effectively teaching this challenging topic. We conclude our study by suggesting a method that teachers can use to further improve their teaching effectiveness.

The purpose of the study was to examine the current status of prospective elementary school teachers' mathematical beliefs. 339 future elementary school teachers majoring in mathematics education from 4 universities participated in the study. The questionnaire used in the TEDS-M(Tatto et al., 2008) was translated into Korean for the purpose of the study. The researchers analyzed the pre-service elementary teachers' beliefs about the nature of mathematics and about mathematics learning. Also, the results of the survey was analyzed by various aspects. To determine differences between the groups, one-way analysis of variance was used. To check the relationship between beliefs about the nature of mathematics and about the mathematics learning, correlation analysis was used. The results of the study revealed that the pre-service elementary teachers tends to believe that the nature of mathematics as 'process of inquiry' rather than 'rules and procedures' which is a view that mathematics as ready-made knowledge. In addition, the pre-service elementary teachers tend to consider 'active learning' as desirable aspects in mathematics teaching-learning practice, while 'teacher's direction' was not. We found that there were statistically significant correlation between 'process of inquiry' and 'active learning' and between 'rules and procedures' and 'teacher direction'. On the basis of these results, more extensive and multifaced research on mathematical beliefs should be needed to design curriculum and plan lessons for future teachers.

In this study, we design a teaching unit that constructs Pascal graphs and extended Pascal triangles to explore number patterns inherent in them. This teaching unit is designed to consider the diachronic process of teaching-learning by combining Dörfler's theoretical generalization model with Wittmann's design science ideas, which are applied to the didactical practice of mathematization. In the teaching unit, considering the teaching-learning level of prospective teachers who studied discrete mathematics, we generalize the well-known Pascal triangle and its number patterns to extended Pascal triangles which have directed graphs(called Pascal graphs) as geometric models. In this process, the use of symbols and the introduction of variables are exhibited as important means of generalization. It provides practical experiences of mathematization to prospective teachers by going through various steps of the generalization process targeting symbols. This study reflects Wittmann's intention in that well-understood mathematics and the context of the first type of empirical research as structure-genetic didactical analysis are considered in the design of the learning environment.

A questionnaire was administered, and all responses were analyzed to examine prospective teachers' conceptual understanding of the relationship between dew point temperature and absolute humidity in air parcels. The responses revealed that many prospective teachers have substantial misconceptions about the relationship. For example, some thought that the absolute humidity and the dew point temperature are proportional to each other, and that the dew point temperature is proportional to the water vapor mass in the parcel. The misconceptions seemingly stemmed from inadequate descriptions on the relationship in middle-school science textbooks of the 7th and 2007 revised curricula. The study notes that the first year students' textbook of the 2015 revised curriculum introduced the concepts of evaporation, condensation, and volume changes as a function of gaseous pressure and temperature, from a perspective of molecular motion. It is suggested that keeping this perspective in the middle school curriculum, while introducing water vapor pressure as the measure of water vapor amount and dew point temperature, should help prevent middle school teachers and students from having misconceptions. There should be a concerted effort to make the science curriculum more consistent and coherent across the grade levels.

Lately, as the importance of software and the software education has been emphasized, the studies on ways of teaching programming to elementary students have been actively progressed. However, most of undergraduates as prospective elementary teachers who will be in charge of teaching programming at the elementary schools have a lack of interest in programming education as well as of the understanding of basic programming principles. Therefore, this study investigated how programming education using hands-on robot and scratch affected learning motivation and academic achievement of preliminary teachers. The comparison of results of two programming educations shows that the programming education using hands-on robot revealed statistically significant difference in learning motivation and academic achievement.
