Worksheets with various levels are major instructional material in open classroom, but sometimes they have been arbitrarily developed in elementaryschools. Especially, pedagogical elements of science course seem to have been neglected in developing science learning papers. To solve these problems, a model of worksheets was developed considering the contextual nature of science knowledge and educational constructivism. The frame of this model is composed of inquiry skill and context, which are two dimensions of each learning task. The level of each worksheet was determined by the level of inquiry skills and the familiarity of contexts.

A convolution neural networks (CNNs) has demonstrated outstanding performance compared to other algorithms in the field of face recognition. Regarding the over-fitting problem of CNN, researchers have proposed a residual network to ease the training for recognition accuracy improvement. In this study, a novel face recognition model based on game theory for call-over in the classroom was proposed. In the proposed scheme, an image with multiple faces was used as input, and the residual network identified each face with a confidence score to form a list of student identities. Face tracking of the same identity or low confidence were determined to be the optimisation objective, with the game participants set formed from the student identity list. Game theory optimises the authentication strategy according to the confidence value and identity set to improve recognition accuracy. We observed that there exists an optimal mapping relation between face and identity to avoid multiple faces associated with one identity in the proposed scheme and that the proposed game-based scheme can reduce the error rate, as compared to the existing schemes with deeper neural network.

In this study, we investigated the processes of analogy change and the characteristics of discussions in collaborative activity of self-generated analogy. Twenty-four high school students in Seoul participated in this study. We implemented science instructions based on collaborative activity of self-generated analogy. We compared personal analogies, group analogies, and modified group analogies in order to analyze the processes of analogy change. We also analyzed the characteristics of group and classroom discussions in the science instructions. The analyses of the results indicated that the processes of analogy change were categorized into three patterns; adding shared attributes, recognizing unshared attributes, and revising mapping errors. They selected a group analogy from analogies of their group members by considering inclusiveness, originality, and familiarity. They perceived the activity of self-generated analogy as subjective and creative. Therefore, they felt little pressure of self-generated analogy and there were little conflicts in group discussions. On the other hand, various analogies were suggested in classroom discussions and the competitive atmosphere of classroom discussions led students to focus on unshared attributes. At the stage of modifying group analogies, they added unshared attributes as limitations of the group analogy and changed their group analogy not to have unshared attributes. There were no cases of generating a new analogy. Some suggestions to implement collaborative activity of self-generated analogy in science teaching effectively are discussed.

This study is performed to understand a trend of preference about classroom for special purposes related with elementary school relocation. It is anayzed based on the questionnaire of teachers at work in the two schools having similar educational environment. The results showed that it is desirable to locate rooms for science or practice in low story and music room in the lowermost or uppermost story. Rooms for art, linguistic education and computer had not limited any place. It is shown that the scale of each preparation room is significantly different with each grade and more large scale is needed in higher grade. These results reflect that the present arrangement of classrooms for special purposes is not adequate and require more reasonable arrangement with the grade in the architectural plans for relocation-needed elementary schools.

Ministry of Education, Science And Technology, from 2009 to 2014, try to establish the setting of Department System in the Middle Schools and High Schools. They selected 45 Schools in 2009 and 61 Schools in 2010 for the Advanced Department System. I studied 2 High schools in 2009 and 3 High schools in 2010 of them, which located in GyeongGi-Do. I studied the Location of Department Classrooms, Teachers' Labs, Homebases and Resting Spaces of them. The conclusions are follows. 1) Most of them take Horizontal Zoning System in the Department Classrooms. 2) The Number of Teachers' Labs were increased in most of floors. On the other hand, most of Labs' Area were decreased. Every department Classroom Zone has one Teachers' Lab. 3) Every schools took much more spaces of Homebases and Resting Spaces than before. And various Resting Spaces using Corridors and Outdoors are prepared for students, those who moves every changing class time by the Department System.

This paper discusses the effect that classroom demonstrations have on students' conceptual understanding in concepts in introductory physics. We used the same conceptual survey to probe the students' understanding on certain concepts before and after taking the course. We introduce Hake's , which is used to evaluate the effect of various kind of teaching methods, suggested by physics education research groups, on conceptual understanding of students who took the class. The effect of physics class using demonstration turned to be better than the traditional lecture, higher for students who graduated from science schools with higher prior knowledge and demonstration experience. Authors suggest to use to probe concepts which need more attention.

Asynchronous Learning Networks (ALN) has become a kind of prevalent information systems to supplement or even substitute a traditional classroom face-to-face teaching method. In this paper, we investigate the impacts of types of courses, lecturers' instruction models and computer self-efficacy on the ALN effectiveness in teaching from lecturers' perspective. We conducted survey to professors in various faculties such as School of Computing, Faculty of Arts, Science, Business, Law and Engineering in the National University of Singapore. According to the responses from ninety-eight professors, instruction modes positively influence the usage of ALN; types of course and lecturers' computer-efficacy influence lectures' satisfaction of ALN in teaching. Both the usage of ALN and satisfaction of ALN positively influence the effectiveness of ALN. The results of this study fill the gap of ALN researches in education by examining it from lecturers' perspective and enable schools to improve their implementation of ALN systems based on our findings.

This paper explores the attitudes of accounting students toward knowledge sharing at Umm Al-Gura University for the academic year 2013-2014. The study explored knowledge sharing among 202 accounting students at Umm Al-Gura University in session during the 2013-2014 academic year. Primary data came from a 3-item questionnaire collected from students; secondary data were source from scholarly publication. Descriptive statistics was used. The findings of this study revealed that the students had a medium to high degree of positive attitude toward knowledge sharing. The students had a positive perception of the use of knowledge sharing in supporting their education. The findings are essential for several stakeholders, such as university policymakers, lecturers, and the students, to provide a deeper understanding of knowledge sharing at the university education level. The findings may encourage policymakers at the university and the classroom levels to organize activities that promote knowledge sharing such as seminars, symposiums, or knowledge sharing exercises during the classroom hours to raise the students' knowledge sharing behavior and enhance education. The results of this study should be useful to policy makers at the university level and the classroom level as there is a positive attitude in disseminating knowledge in the higher educational setting.

Research shows that formative assessment has a more powerful effect on student learning than summative assessment. This case study of an 8th grade algebra classroom focuses on how the implementation of Formative Assessment Lessons (FALs) and the participation in teacher learning communities related to FALs changed in the teacher's instructional practices, over the course of a year, to promote students' mathematical reasoning and justification. Two classroom observations are analyzed to identify how the teacher elicited and built on students' mathematical reasoning, and how the teacher prompted students to respond to and develop one another's mathematical ideas. Findings show that the teacher solicited students' reasoning more often as the academic year progressed, and students also began developing mathematical reasoning in meaningful ways, such as articulating their mathematical thinking, responding to other students' reasoning, and building on those ideas leading by the teacher. However, findings also show that teacher change in teaching practices is complicated and intertwined with various dimensions of teacher development. This study contributes to the understanding of changes in teaching practices, which has significant implications for teacher professional development and frameworks for investigating teacher learning.
