There has been an increasing concern of whether a real instructional change happens in a way to promote students' mathematical development. Against this background, this paper dealt with successes and difficulties an elementary school teacher went through as she moved on to student-centered instruction. The analysis drew on classroom observations for one year to illustrate how the teacher and students established social norms, sociomathematical norms, and classroom mathematical practices that could emphasize mathematical sense-making and justification of ideas. Close analysis showed many gradual but dramatic changes in terms of mathematics classroom culture. This led to consider possibly subtle but crucial issues with regard to implementing student-centered instruction.

This article analyzes the academic achievement of students who entered A university from 2011 to 2012 using grade point average (GPA). The purpose of this analysis is to find the relationship between admission factors and academic achievement. Contrary to our expectation, GPA of student selected from KSAT is higher than that of selected from CSAT. So, designing and running university entrance type, it is necessary to consider admission factors deliberately.

The purpose of this study is to develop and apply activity-based STEAM education programs to verify elementary school students' logical thinking skills, attitudes to STEAM, and changes in satisfaction. The activity-based STEAM education program was developed in a total of 3 rounds under the theme of 'Let's get through Ultraviolet rays.' The finally developed program, which was revised and supplemented by process of preliminary commitment to elementary school students, proved its effectiveness through statistical methods in 168 sixth-grade in S elementary school students in Gyeonggi-do. The results of the study are as follows: First, the activity-based STEAM education program was developed around the topic of "Let's get through Ultraviolet rays" based on the "The solar system and Star" unit of the 5th and 6th grades of elementary school science. Second, by applying the developed activity-based STEAM education program to elementary school students, their cognitive development level by science behavioral system was improved after class, and proportion of the logical thinking skills and logic of variable control represented a significant value(p<.05). Third, the attitudes toward STEAM education, consisting of seven sub-factors, presented significant statistical test results across other factors, except for communication and usability factors(p<.05). Fourth, in the satisfaction test, the average value of the lower section was 3.59 to 3.85 points, and overall it was positive.

미래의 교육은 전통적인 면대면 방식으로 이루어지는 오프라인 학습과 컴퓨터와 네트워크를 활용한 온라인 학습이 통합적으로 이루어지는 학습체계 속에서 교과서의 지식을 학생들에게 전달하는 방식의 기존 교육과는 매우 다른 모습을 보일 것이고, 학습자 중심의 개인별 맞춤식 교육을 지향하고, 원활한 의사소통 방법을 이용하여 협력 중심의 활동을 강조할 것이다. 이에 교육현장에서는 다양한 이론과 연구를 통해 교수 학습방법 개선하고, 기초 기본 학력 신장에 끝없는 노력을 기울여 왔다. 하지만 이처럼 부단한 노력에도 불구하고 기초 기본 학력의 성취 수준이 부족한 학생은 여전히 대부분의 학급에서 많이 존재하고 있다. 때문에 학생들의 학력과 교사의 지도방법을 신뢰하지 못하는 학부모들은 자녀들을 어릴 때부터 사교육으로 내몰고 있는 것이 우리 교육의 현실이다. 이러한 현실에 공교육을 보완하기위해 등장한 사이버가정학습이 그 취지에 맞게 공교육울 내실화하여 학부모와 학생들에게 신뢰성을 회복한다면 사교육비 경감 효과와 더불어 제대로 된 학교 교육의 정체성을 확보하게 될 것이다. 이에 본 연구에서는 블렌디드 학습모형의 하나인 온라인 보충학습 결합모형을 적용하여 학생들에게 학습에 대한 흥미와 지적 호기심을 자극함으로써, 기초 기본학습의 내실화가 이루어져 결과적으로 학생들의 기초 기본학력이 신장되었음을 확인하였다.

This study aims to reflect on mathematical imaginations in learning mathematics and elementary students' mathematical imaginations. This was approaching a study of imagination not as psychological problems but as objects and methods of mathematics learning. First, children's mathematical narratives were analysed in terms of Egan(2008)'s basic cognitive tools using imagination, that is, metaphor, binary opposites, rhyme rhythm pattern, jokes humor, mental imagery, gossip, play, mystery. Second, how children's imaginations change under different grades was addressed.

This study aims to present the effects of discussion-centered reading education on high school students' personality & sociality using omnidirectional reading-discussion programs. To this end, we adopt an experimental research design with pre/post-test on personality and sociality using the program with the first and second grades high school students located in Chungju City as participants. The results show that the discussion-centered reading education has significant effects on the personality and sociality of high-school students.

The purpose of this study was to investigate addition strategies of the 1st year elementary school students compared to the strategies recommended by the 7th national curriculum. We used interviewed children's worksheets to analyze the children's strategies. The results of the study showed that the formal strategies the textbook recommended and the children's strategies were so different. Teachers need to articulately comment two strategies when they teach mathematics in the classrooms.

Perception of the experiment is one of the most important factors of students' understanding of scientific inquiry and the nature of science. This study examined the perception of middle and high school students of the meaning of 'experiment' in the biological sciences. Semantic network analysis (SNA) was especially used to visualize students' perception structure in this study. One hundred and ninety middle school students and 200 high school students participated in this study. Students responded to two questions on the meaning of 'experiment' in science and biology. This study constructed four semantic networks based on the collected response. As a result, middle school students about the 'experiment' in science are 'we', 'direct', 'principle' of such words was aware of the experiments from the center to the active side. The high school students' 'theory', 'true', 'information' were recognized as an experiment that explores the process of creating a knowledge center including the word. In addition, middle school students relative to 'experiment' of the creature around the 'dissection', 'body', high school students were recognized as 'life', 'observation' observation activities dealing with the living organisms and recognized as a core. The results of this study will be used as important evidence in the future to map out an experiment in biological science curriculum.

The purpose of this study is to develop and apply the algorithm teaching materials centered on plays(ATMCP) to improve problem-solving abilities of elementary students. For this goal, the ATMCP were reviewed by the expert group and tested them out on 71 fifth-grade elementary students in Daegu, Korea during the 6 weeks. We divided students into two groups: one is the group of the ATMCP and the other is the group of conventional algorithm teaching materials(ATM). And we analyzed the change of the problem-solving ability of each group between before and after using two types of teaching materials with the Mixed ANOVA. The result showed that there was a significant difference in students' problem-solving abilities between before and after using them and the group of the ATMCP was greater improvement than the group of the conventional ATM in a problem-solving ability.

The study aims to run a 'Process-based Evaluation' and find out its effectiveness in science classes for prospective elementary school teachers. The Process-based Evaluation performed in this study was performed during unit classes and scored when significance was recognized in the student's learning behavior. The conclusions based on the results of the study are as follows. First, students scored an average of 3.6 points on whether the process-oriented assessment conducted during class was appropriate as an assessment. Second, on the basis of the assessment presented by the students, the main positive content is "assessing the process, not the outcome", "contributing positively to class participation" and "promoting accident activities". Third, the negative contents of the assessment grounds presented by the students include 'lack of objectivity in evaluation methods and results', 'the individual tendencies of students are involved in evaluation results' and 'poor learning effects of the textbook knowledge'.
