The purpose of this study is to investigate the relationships between moral sensitivity for topics related to science and preference for science, and belief about learning science. 129 middle school students were involved in this study and completed questionnaires to measure moral sensitivity for topics related to science, preference for science, and belief about learning science. Students' responses were analysed to show the distribution of variables and the correlation between variables by gender and grade. As a result, moral sensitivity was not affected by respondents' grades and genders, but was affected by different topics. Preference for science was not affected by respondents' grades and genders, while belief about learning science was not affected by respondents' genders but affected by lower grade. There were correlations between students' moral sensitivity and preference in case of female students and higher grades, as well as relationship between moral sensitivity and belief about learning science. This result infers that students who have higher moral sensitivity can prefer science and show more positive belief about learning science. Also, it can implicate that affective domain including interest or belief can play an important role in the context of science education focusing on moral aspect or ethics, and that teachers should be aware of personal differences in case of teaching moral aspect of science.

In order to enhance instructional effects of multimedia contents, it is critical to emphasize the importance of interface and the affective aspects of learner characteristics in design processes. The main aim of this research was to assess the needs for evaluating icon design strategies on the basis of children's sensibilities by investigating differences between children and teachers in their sensibilities to the icons used in multimedia contents for elementary education. Some interesting findings were obtained from the research. Children had richer sensibilities to the icons presented in multimedia contents than teachers in terms of the average number of adjectives reflecting sensibilities. Among the children group, children living in urban areas showed richer sensibilities to the contents than those in rural areas. When the frequencies of the use of 5 adjectives commonly used by the two groups were compared, teachers showed positive sensibilities, but children demonstrated some negative sensibilities. Also children demonstrated richer sensibilities to certain contents than teachers. The results of the research indicated the need for evaluating icon design strategies on the basis of children's sensibilities in designing multimedia contents for children.

This paper investigated the views of effective mathematics instruction on the part of teachers. The study was carried out a survey with 223 elementary school teachers in Korea. The questionnaire consisted of the following 4 main categories with a total of 48 factors: (a) the curriculum and content, (b) teaching and learning, (c) classroom environment and atmosphere, and (d) assessment. Some ideas teachers revealed about what would enable good mathematics teaching coincided with previous research. Specifically, teachers agreed with the idea of consideration of students' individual differences or focus on concepts. However, there were differences with regard to the use of technology and the importance of learning environment, which have been emphasized in mathematics education literature. Considering that the teacher plays a key role in implementing good instruction, this paper emphasizes us to attend to teachers' perspectives in order to initiate good teaching at the actual classroom.

The primary purpose of this study was to investigate how sixth grade elementary school students react to the types of letters use, what levels of understanding letters students are in and what difficulties are in understanding letters, and to raise issues about instructional methods of algebra. A descriptive study through pencil-and- paper tests was conducted. The test instruments consisted of 18 questions with 6 types of letters use. According to the results of testing, students' types of letter use and the levels of understanding letters were classified. The conclusions from the results of this study were as follows: First, the higher the types of letters use, the more sixth grade elementary school students had low scores on the types. Therefore, teaching methodologies of letters and expressions in the classroom need to encourage for students to improve their ability of using and understanding letter. Second, approximately 40% of students were categorized in level 3. Accordingly it is necessary to have a program of teaching and learning to improve their understanding levels of letters. Third, approximately 15% of students were categorized in level 0. In order to develop understanding of letters, it is important that students use letter evaluated and letter used as an object. Fourth, students had the difficulties in understanding letters. It is informative for teachers to understand these students' difficulties and thinking processes. Finally, we must treat the different uses of letters and introduce them successively according to the student's understanding levels of letters.

Fraction division is the content that is important but difficult to learn because it includes the process of finding a numerical expression in the real-world context, the process of making a context that matches a numerical expression, how to solve division, and the justification of standard algorithm. This study analyzes the word problems and problem solving methods about fraction division which elementary pre-service teachers represented. Pre-service teachers have more difficulty in making word problem where the dividend is less than the divisor and they also show typical errors in making the word problems. There were differences in the methods presented according to the contexts of division in problem solving. Through this study, it is necessary to rethink the teaching methods for fraction division instruction in the curriculum for pre-service teachers and analyze the formation process of 'knowledge for content and teaching' because of the differences in responses between grades.

The purpose of this study is twofold: (i) to develop a teaching and learning plan and practical performance assessment tools for the improvement of teenager-parent communication and relationships as well as explore their effects on the communication in the everyday family life; and (ii) to find the underlying problems of teenager- parent communication through conversation analysis and to provide a improved dialogue model. We provided the experimental group with a performance task of communication training between teenagers and their parents in the real family situation while the control group practiced communication skills in a learning situation. However for both classes, before and after performance tasks were equally provided. The experimental group exhibited a longer conversation time with their parents, better communication skills, and higher degrees of relational satisfaction than the control group. Conversation analysis revealed that the experimental group reduced the use of blocking techniques in the teenager-parent conversations more than the control group, and all so raised the frequency of functional communications more than the control group. In both areas of communication in the experimental group was significantly improved, Most notably, a problem-solving case through no-lose conflict resolution methods was effective, succeeding by 70% in the e experimental group and 43.3% in the control group. Parents use blocking techniques like admonition, lecturing, blaming. sarcastic remarking, ordering and so forth, while teenagers use dispute, avoidance, blaming, and teasing in this order. The communication problems during the conversation process, teenagers' evasive and rebellious way of speaking instigates adverse communication responses from parents, so their conversation tends to unfold as ambiguous evasion opposed to: inquiring or evasion by short answers vs. ordering-preaching, or disputing vs. criticizing-making sarcastic, disputing vs. disputing-teaching, and criticizing vs. criticizing.

In order to enhance the effect of Problem-based Learning, the role of scaffold as a learning support strategy is necessary. Collective intelligence provides scaffolding in the sense that it integrates users' knowledge, information, experiences, values, etc. Based on these factors, collective intelligence determines the direction of behavior, revises the direction continuously, and provides problem-solving methods. Teaching and learning situations emphasize learners' initiative, voluntary, and active participation. Thus, this study was conducted to find out if collective intelligence can be an effective and attractive alternative of learning strategy. Specifically, this study purposed to examine how collective intelligence performs the role of scaffold on the Web and what types of scaffolding are provided to learners. According to the results of this study, collective intelligence had a positive effect on learners' learning attitude, confidence, interest, etc. in the affective aspect, but its effect on the cognitive aspect was different according to learners' school year and learning level. Because collective intelligence had a positive effect on learners, we identified scaffolding types explanation, suggestion of direction, illustration and feedback in the cognitive aspect, and positive response and encouragement in the affective aspect.

The purpose of this study was to investigate the development and application of strategies using fairy tales in elementary school science. For this study, many fairy tales were searched in terms of various characteristics and educational value of the tales. Five fairy tales were selected and reconstructed to suit the 'mirrors and lenses' unit of 5th graders' school science, and teaching strategies using the fairy tales were developed to be used in six lessons. To investigate the effects of instruction using fairy tales, pre/post tests for scientific attitude were administered. To analyze students' perception of their classes, a simple survey was administered through questionnaires. We found from this study that the students related the fairy tales with their own experiences and took an active part in the class that used them. Also, instruction using fairy tales had positive effects on their scientific attitude. Many students said that the science classes were interesting, and the method using fairy tales encouraged students to study hard as well as helped them to understand the context. It was concluded that instruction using fairy tales was an effective method in terms of enhancing learning motivation, encouraging more inquiries, more opportunities to apply the scientific concept, and more positive scientific attitude. We discussed the strategies using fairy tales for implementation in elementary science classes as well.
