The study aims to figure out pre-service elementary teachers' knowledge understanding on 'stratum and rock' as well as teaching-learning types on the same topic. A total of 65 seniors in an advanced science education course at B University of Education joined the research to fulfill the purpose above. With PCK classification framework, the study examined pre-service teachers' knowledge understanding on 'stratum and rock' while it analyzed how the teachers would teach the given topic to students. The results of the study are presented as follows. First, it was observed that the pre-service elementary teachers have a great understanding on 'stratum and rock' that would be taught via a science textbook for elementary fourth graders. However, regarding terms in 'shale and limestone', they appeared to have a relatively short understanding. Second, PCK elements of the pre-service teachers related to 'stratum and rock' were analyzed and according to the results, the teachers would be interested in teaching model selecting in the teaching-learning strategy field while they would be well aware of how important it is for them to perform an experiment in a teaching process. The teachers also appeared to understand that the teacher question can be mutual complementary during class. However, it turned out that the teachers would have a very much low understanding on learners' prior knowledge as they particularly believe that learning could be significantly affected by the learners' perception level as well as their learning interest and motive. Third, the pre-service elementary teachers were told to design teaching plans on 'stratum and rock' so that the study could find out what learning-teaching methods the teachers would adopt to teach the topic. It was learned that the teachers would proceed with the class basically by giving the learners a descriptive explanation on the topic and also by using pictures and drawings to enhance the learners' understanding during the class.

이 연구에서는 과학학습에 대한 동기적 신념과 자기주도 학습능력을 각각 과학 개념 이해에 영향을 줄 수 있는 구인으로 가정하고, 이들의 관계를 정량적으로 탐색하고자 하였다. 이를 위해서 이 연구에서는 중학생들을 대상으로 과학학습에 대한 동기적 신념과 자기주도 학습능력, 물질 변화에 대한 개념 이해에 대해 기존 연구의 측정도구를 이용하여 각각 조사하고, 조사한 응답 분포를 바탕으로 이 세 변인 간의 인과 관계를 PLS 구조방정식모형을 통하여 분석하였다. 연구 결과, 이 연구에서 설정한 잠재변수인 과학학습에 대한 동기적 신념, 자기주도 학습능력, 물질 변화 개념 이해의 측정은 신뢰도와 타당도 면에서 통계적으로 적합한 것으로 나타났다. 또한, 잠재변수들 간의 인과 관계를 분석한 결과, 자기주도 학습능력은 동기적 신념과 물질 변화 개념 이해에 모두 영향을 미치지만, 동기적 신념은 자기 주도 학습능력에만 영향을 미치고 물질 변화 개념 이해에는 영향을 미치지 않았다. 이 연구를 통하여 과학학습 상황에서 자기주도 학습 능력만이 과학 개념 이해에 직접 영향을 미치며 동기적 신념은 간접적으로만 영향을 미친다는 것을 확인할 수 있었다. 이 연구는 과학학습 과정에 관여하는 변인들 간의 인과적 관계를 정량적인 방법을 통해서 확인했다는 점과 과학교육 연구 분야에서 PLS 구조방정식모형을 새로운 연구방법론으로써 제안한다는 점에서 의의가 있다.

In the elementary science classroom, inquiry-based learning activities are often limited to students' hands-on experiences. As a result, students often overlook core concepts they are supposed to acquire from the inquiry activities and show difficulties in applying those concepts in a real life context. To make a connection between the hands-on activities and the concept leaning, a small-group discussion can be considered. In this study, we designed a team-based learning (TBL) model for the elementary science classroom. We developed teaching and learning materials for the "Comfortable Environments" unit in the 6th grade curriculum based on the TBL model. After appling the model with 32 6th grade students, we compared the TBL participants' level of concept understanding and attitudes toward science before and after the intervention, and also compared them with their counterpart control group who participated in a traditional classroom. The results showed that the level of concept understanding of the TBL participants were higher than that of the control group. However, there was no statistically significant difference found in attitudes toward science between the TBL participants and the control group. In addition, the interviews with the TBL participants showed that they positively perceived the TBL experiences.

Construction industry still requires a lot of laborers to perform a project despite of advance in technologies, and improving labor productivity is an important strategy for successful project management. Since repetitive construction works exhibits learning effect, understanding laborers' learning phenomenon therefore allows managers to have improved labor productivity. In this context, previous research efforts quantified individual laborer's learning effect, though numerous construction works are performed in group. In other words, previous research about labor learning assumed that sum of individual's productivity is same as group productivity. Also, managers in construction sites need understanding about group learning behavior for dealing with labor performance problem. To address these issues, the authors investigate what variables affect laborers' group level learning process and develop conceptual model as a basic tool of productivity estimation regarding group learning. Based on the result of this research, it is possible to understand forming mechanism of learning within the group level. Further, this research may contribute to maximizing laborers' productivity in construction sites.

A recent survey of Australian directors conducted by the Financial Reporting Council found that directors require a detailed understanding of technical accounting issues. With the aim of understanding learner difficulties in learning and applying higher learning material relevant to directors, this study explores the transfer pricing topic taught as a case presentation in an undergraduate accounting program at an Australian university. Before intervention with improvements, this study invited 25 students to take part in the study after they had learned the topic and been given one week to understand it. By adopting a transfer pricing problem presented in their essential reading and interviewing those students to gain further insights, the study found that learners experienced conceptual difficulties at various stages in attempting to learn. Intervention to ease learning difficulties was addressed through instructor training. The intervention improvements included using guided workbooks to develop a better understanding of concepts among learners, and representing the problem at hand with diagrams. After intervention with improvements, this study repeated the same procedures with 25 students who had not taken part in the previous study and found that interventions increased the learning. Results have implications for most directors, who are novices to the detailed technical accounting issues of transfer pricing.

The concept of variables is central to mathematics teaching and learning in junior and senior high school. Understanding the concept provides the basis for the transition from arithmetic to algebra and necessary for the meaningful use of all advanced mathematics. Despite the importance of the concept, however, much has been written in the last decade concerning students' difficulties with the concept. This Thesis is based on research to investigate the hypothesis that LOGO programming will contribute to 6th grader' learning of variables. The aim of the research were to; .investigate practice on pupils' understanding of variables before the activity with a computer; .identify functions of LOGO programming in pupils' using and understanding of variable symbols, variable domain and the relationship between two variable dependent expressions during the activity using a computer; .investigate the influence of pupils' mathematical belief on understanding and using variables. The research consisted predominantly of a case study of 6 pupils' discourse and activities concerning variable during their abnormal lessons and interviews with researcher. The data collected for this study included video recordings of the pupils'work with their spoken language.

The aim of this study is to show that using a Web-Based Instruction system is a better method to help counteract deficient teaching, learning conditions and facilities thus improving the students' interest, understanding, participation and skill development in Physical Education. The key findings of this study are as follows; The first advantage of using this system is that the theory of Softball is explained with the use of pictures rather than text, thus improving the students' understanding. The second is the method in which practical skills are explained and demonstrated. Action image sequences are used as opposed to the old method of using stationary pictures. This means that the learners can clearly see and understand why and, more importantly, how to use these skills. The third advantage is the technique used to teach the application of these skills. Using active rather than passive learning and thus engaging the student encourages improved participation and learning. The fourth advantage comes in evaluation: both subjective and objective questions are asked in theoretical evaluation, and the teachers can evaluate the students' understanding and skill development by filming their actual Softball games. The final advantage is the use of Self-Directed Learning to aid learners' development of understanding of the lesson content as interactions between teachers and learners are constructe

Urban planning and engineering undergraduate students need to understand the earth physical systems and that how human beings interact with the earth systems to planning and engineering urban area. The eco-friendly or geo-friendly design and planning of an urban area is a critical issue not only for economic benefits but more importantly for the sustainable future of urban life. However, little study has been done dealing with the urban engineering students' understanding of the earth as a system and what pedagogical approach is appropriate to improve their understanding of the earth as a system. This study is to investigate the impact of a purposely designed ESS course on urban engineering students' understanding of the earth as a system and their perceptions about the instructional approaches of the course on their learning competency. This study utilized a mixed-methodology with three main data sources: concept maps, student's perception survey about their learning competency, and course contents. Both the survey and concept maps were analyzed quantitatively as well as qualitatively. The result of this study showed that the urban engineering students' experience of team-based research about the topic they chose based on their own interest had a positive impact on their understanding of the earth as a system and their learning competency. The results of this study suggest that structuring and presenting the earth system contents in the context of engineering students' understanding and their future career be effective not only for the improvement of students' content knowledge but also for the enhancement of their learning competency such as creativity and problem-solving skills in everyday life situation.
