The purpose of this study is to investigate the effect of concept mapping strategies on the learner's achievement and their attitude change in science learning. The subject was 159 male students in a middle school in Seoul. Three experimental groups were instructed with different kinds of teaching methods about the unit of photosynthesis and digestive organs. Group I was instructed with traditional teaching method, GroupII was instructed with guided concept mapping strategy, GroupIII was instructed with student-centered concept mapping strategy. The major findings of this study are as follows. 1. Student-centered concept mapping strategy was observed effective at 0.05 significance level in achievement and retention. 2. Only student-centered concept mapping strategy changed students' attitude toward science learning positively. 3. It was observed that there was very significant correlation between the learning ability and science achievement (p<0.01). 4. Student-centered concept mapping strategy was found effective in upper learning-ability group, and guided concept mapping strategy in middle learning-ability group(p < 0.05). 5. Student-centered concept mapping strategy was effective to the groups of upper and middle learning-ability in changing students' attitude toward science learning(p < 0.05).

본 연구에서는 상황 학습 이론과 실행 기반의 과학 교육에 관한 문헌들에 대한 고찰을 통해 과학적 실행 중심의 수업에서 과학 개념학습의 가능성을 살펴보았다. 먼저, 상황 학습 이론이 학생들의 과학적 실행에의 참여를 강조하는 최근 과학 교육 개혁의 흐름과 관련이 깊으며, 상황 학습의 관점에서 개념 학습은 학습자가 개념을 자원으로 활용하며 실행에 참여하는 동안 개념적 행위 주체성을 발현하여 개념을 지속적으로 발전시키는 과정을 통해 이루어진다는 것을 알 수 있었다. 또, 이러한 상황 학습 이론은 과학적 실행 기반의 수업에서 과학 개념을 학습하는 데에도 적용된다는 것을 확인하였다. 즉, 과학적 실행 중심의 과학 수업에서는 과학 개념이 자원으로 활용되며, 과학 개념을 자원으로 활용하는 동안 학생들은 과학적 실행에 더 잘 참여할 수 있고, 과학적 실천에의 참여는 개념적 행위 주체성의 발현을 통해 개념 학습을 더욱 촉진할 수 있다. 이러한 고찰의 내용이 학교 과학 교육에 주는 시사점을 논의하였다.

과학교육에 있어 지금까지 개발된 수업모형은 마치 과학의 모든 목적을 달성시켜줄 것 같지만 실제 교육현장에 적용해 보면 기대하던 효과를 얻지 못하는 경우가 많다. 수업의 효과를 극대화하기 위해서는, 어느 한가지 방법만을 고수하는 것보다 개발된 수업모형을 유연성 있게 활용 할 수 있는 교사의 수업전략이 필요하다. 본 연구는 개념도와 순환학습을 통합한 수업이 개념도를 활용한 수업이나 순환학습과 비교하여 고등학생들의 학업성취도 및 과학적 탐구능력, 과학에 대한 태도에 어떠한 영향을 주는지 알아보는데 그 목적이 있다. 연구대상은 고등학교 2학년 여학생 324명으로, 개념도-순환학습 집단, 개념도 활용 집단, 순환학습 집단, 전통적 수업 집단의 4집단으로 나누어 수업하였다. 연구 단원은 고등학교 과학의 '생식과 유전' 단원으로 약 10주간 10차시에 걸쳐 수업처치 하였다. 수업처치 전, 후에 학업성취도 검사와 과학적 탐구능력, 과학에 대한 태도 검사를 실시하였고, 연구결과는 공변량 분석 (ANCOVA과)과 사후 검증(Duncan test)으로 분석하였다. 개념도-순환학습은 학생들의 과학 학업성취도를 향상시키는데 전통적인 수업보다 효과적이었고(p< .05) 그 효과면에서 개념도를 활용한 수업보다 떨어지지 않았다. 성취 수준이 상위와 중위 학생들은 수업방법에 따라 학업성취도에 차이를 보이지 않았으나, 하위학생들은 개념도를 활용한 수업이 가장 효과적이었다(p< .05). 개념도-순환학습은 학생들의 과학적 탐구능력을 신장시키는데 개념도를 활용한 수업이나 전통적 수업보다 효과적이었으며(p< .05) 그 효과 면에서 순환학에 떨어지지 않았다. 성취수준이 상위인 학생은 수업방식에 따라 과학적 탐구능력에 차이를 보이지 않았으나, 개념도-순환 학습은 중위와 하위 학생들의 과학탐구능력 향상에 순환학습 만큼 효과적이었다. 개념도-순환학습은 학생들의 과학에 대한 태도를 향상시키는데 전통적 수업보다 효과적이었으며(p< .05) 그 효과 면에서 개념도 활용 학습이나 순환학습에 뒤지지 않았다. 따라서 개념도 순환 학습은 모든 학생들의 수준을 고려 할 때 학생들의 학업성취도를 향상시키고, 과학적 탐구능력을 신장시키는데 개념도 활용학습이나 순환학습을 단독으로 적용하는 것보다 긍정적이라고 할 수 있다.

Recently the concept of learning has become very fashionable among academics from different economic disciplines. Economic geographers and spatial planners joined this fashion by increasingly speaking about the 'learning region'. This paper makes clear that this learning region'. This paper makes clear that this learning region concept has been launched from three angles; as spatial outcome of grand societal changes, as spatial concentration of entrepreneurial learning for innovation and as regional development concept. Despite the deficits and flaws such a young concept is faced with, such as vague definitions, the lack of empirical research and an insufficiently clear separation from existing concepts, the learning region concept might provide economic geography with more insight in agglomeration effects, stronger links with policy-making and more knowledge on path dependency and thus on unravelling the distinction between 'good' and 'bad' industrial agglomerations.

The purpose of this study is to examine the effects of background knowledge on problem solving. To achieve this aim, I proposed the model which shows problem solving process centering around background knowledge, conducted the lessons concerning the concept 'weightlessness' on pre-service elementary teachers, and then classified the pre-service elementary teachers into several groups by the difference of the results presented in the process of solving the problems on weightlessness. And I examined qualitatively the effects of background knowledge on problem solving through the interview with 11 volunteers. On the cause of the failing the problem solving, the failure of acquiring or activating the background knowledge related to the learning concept was most frequently, secondly the use of the background knowledge unrelated to the learning concept, and thirdly the failure of understanding the teaming concept. To acquire or activate the background knowledge related to the teaming concept was more difficult than to understand the new teaming concept, and the cases that use the background knowledge unrelated to the learning concept failed to solve problem. The result of interview, all interviewee understood the learning concept correctly, but all of them who fail to acquire or activate the background knowledge related to the learning concept, or use the background knowledge unrelated to the learning concept, could not solve the problem.

In this study, the effects of concept mapping with feedbacks providing explanatory comments on students' achievement, science learning anxiety, and science learning motivation were investigated in the undergraduate general chemistry course. The aptitude-treatment interactions between students' level of mastery goal orientation and the concept mapping with explanation feedback treatment were also examined. Sixty-seven freshmen from an university of education were assigned to a control group and a treatment group. The tests of mastery goal orientation, science anxiety, and science learning motivation were administered as pretests. For the treatment group, feedback providing students with explanatory comments through whole class discussion was presented after each concept mapping. Whereas the control group students were presented with opportunities solving excercise problems followed by explanation feedback. The intervention was lasted for 10 weeks (30 class periods). After the instructions, a researcher-made achievement test, the science learning anxiety test, and the science learning motivation test were administered. The results indicated that no statistically significant difference was found in students' achievement. In the science learning anxiety, however, the scores of the treatment group was significantly lower than those of the control group. The scores of the treatment group also tended to be higher, though not significant, than those of the control group in the science learning motivation. However, no significant aptitude-treatment interactions were found in all dependent variables.

선행연구에서 조사한 화학 변화에 대한 학습자의 선개념과 이를 근거로 개발한 개념변화 수업 지도안 및 학습자의 학습 동기를 고려한 개념변화 수업 지도안을 학생들에게 투입하였을 때, 학습자의 학습 동기에 따라 개념변화 수업 모형의 효과가 어떻게 나타나는지 알아보았다. 본 연구를 통하여 학습자의 흥미나 태도, 동기 등 정의적인 측면을 고려하지 않고 단지 학습자의 인지구조에만 초점을 맞춘 기존의 개념변화 수업 모형틀을 재평가하고자 하였다. 이를 위하여 중학교 2학년 학생들을 대상으로 통제 집단과 실험 집단을 구분하고 수업 전 학습 동기를 조사하였다. 그 후에 '화학 변화' 단원을 전통적인 수업과 개념변화 수업으로 지도하고 사후 학습 동기를 조사하였다. 학습동기를 고려한 개념변화 수업을 받은 집단, 학습자의 인지만을 고려한 개념변화 수업을 받은 집단, 그리고 교과서에 의존한 전통적인 수업을 받은 집단 모두 수업을 받은 후에 학습 동기가 증진된 것으로 나타났다. 특히 학습자의 학습 동기를 고려한 개념변화 수업은 학습자의 인지만을 고려한 개념변화 수업이나 교과서에 의존한 전통적인 수업보다 학습 동기의 증진에 효과적이었다. 이러한 효과는 특히 수업을 받기 전에 학습 동기가 낮았던 학생들에게 더욱 크게 나타났다. 수업에 따른 개념의 이해도 증진의 효과를 분석한 결과에 따르면, 세 종류의 수업을 받은 학생들은 모두 수업 후에 개념의 이해도가 증진된 것으로 나타났다. 그러나 그 중에서도 학습동기를 고려한 개념변화 수업 집단과 학습자의 인지만을 고려한 개념 변화 수업 집단이 교과서에 의존한 전통적인 수업 집단(통제 집단)보다 사후 개념 이해도가 높았다. 특히 수업 전 학습동기가 높았던 학생들은 학습 동기를 고려한 개념변화 수업을 받았을 경우 교과서 중심의 전통적인 수업을 받았을 경우보다 개념의 이해도가 높아진 것으로 나타났다. 또한 수업 전 학습동기가 낮았던 학생들의 경우에는 학습 동기를 고려한 개념변화 수업을 받음으로써 학습동기가 증진하는 것으로 나타났다.

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.

This study investigated the effect of generative concept maps according to learning achievements and cognitive load. A total of 78 students in the first grade of middle school participated in this study. Before the experimental treatment was implemented, students had to fill out a questionnaire assessing prior knowledge. The study was designed where all the students were presented the same learning contents regarding photosynthesis; however, the two experimental groups were provided with different concept map methods: a learner-generative concept map (GCM) and an instructor-provided concept map (PCM). GCM students were asked to make a concept map by themselves in small groups while they are reading material. PCM students were instructed to study in small groups in order to read the material; however, they were provided a concept map developed by their teacher. The control group (CG) had the teacher present the learning contents in traditional lecture format with no accompanying concept map. The results show that there were significant differences in the achievements among the groups. CG showed higher achievement than both the experimental groups. There was also a significant difference in cognitive load. Although the GCM group did not obtain higher achievement than the other groups, the GCM group showed higher mental effort and lower physical fatigue than the other groups. The GCM group might have invested more effort to find and connect ideas when drawing their concept map with peers which is unlike the conditions for the PCM group and CG. In conclusion, we should consider applying GCM in teaching and learning design in order to increase learning achievement and decrease extraneous cognitive load.
