This study is aimed to determine whether there is any meaningful correlation between predictors and is intended to examine the relative influences that the pedagogical content knowledge of science teaching, scientific attitudes, science teaching intentions have on their science teaching efficacy. The results, showed that the childcare center teachers' pedagogical content knowledge of science teaching, scientific attitudes, science teaching intentions, and science teaching efficacy are all correlated with each other. The teachers' science teaching efficacy are predicted by their scientific attitudes, science teaching intentions, and pedagogical content knowledge of science teaching-learning methods. Specifically, for teachers of 0 to 2-year-olds, their science teaching efficacy is predicted by their science teaching intentions and scientific attitudes. For teachers of 3 to 5-year-olds, their science teaching is affected by their scientific attitudes and their pedagogical content knowledge.

This study aims at checking up influences imposed on mathematics learning abilities in communication teaching through small group leaning for the sixth grade pupils of elementary schools. Results obtained through the study are as follow: The communication teaching through small group cooperative learning showed an affirmative reaction in terms of mathematics learning achievement degree and mathematical tendency. However, the pupils of the lower group showed a meager effect in terms of mathematics learning achievement degree. It means that such an effect is required to a sustained teaching for a long time by teachers.

기존 연구에서는 질의 응답 시스템에서 정답 유형을 분류하기 위해 패턴 매칭 방식이나 교사 학습(Supervised Learning)을 이용했다. 패턴 매칭 방식은 질의 분석을 통해 수동으로 패턴을 구축해야 한다. 교사 학습에서는 훈련 데이터 전체에 정답 유형이 태깅(Tagging)되어야 하며, 이를 위해서는 사용자의 질의에 정답 유형을 수동으로 태깅하는 작업이 많이 필요하다. 웹을 통해 정답 유형이 태깅되지 않은 대용량의 사용자 질의 말뭉치를 구할 수 있지만, 이 데이터에는 정답 유형이 태깅되어 있지 않다. 따라서, 대용량의 사용자 질의에 비례하여, 정답 유형을 수동으로 태깅하는 작업량이 증가한다. 앞서 언급한 두 가지 방법론에서, 정답 유형 분류를 위해 수작업이 많이 필요하다는 문제점을 해결하고자 본 논문에서는 일부 태깅된 훈련 데이터를 필요로 하는 반교사 학습(Semi-supervised Learning)에 기반한 정답 유형 분류를 제안한다. 이는 정답 유형 분류 작업에 필요한 노동력을 최소화함으로 대용량의 데이터를 통한 효율적 질의 응답 시스템 구축을 가능하게 한다.

Frequently, pre-service elementary teachers are asked to write reflective journals on their teaching during teacher education program. However, writing reflective journals can not guarantee pre-service teachers to learn from their experience. In this study, 44 reflective journals of pre-service elementary teachers on their science teaching were analyzed in terms of 'productive reflection', a concept suggested by Davis (2006). Productive reflection may help teachers' effective learning by considering interrelationships among aspects of teaching including learners and learning, subject matter knowledge, assessment, and instruction. The result showed what aspects of teaching were included, emphasized, and integrated in the pre-service elementary teachers' reflective journals. Implications for teacher education would be discussed.

본 연구는 전통적인 교사위주의 설명식 수업을 벗어나 인터넷을 학습에 보다 효과적으로 활용하는 방법을 모색해 보고자 하는 것이다. 이를 위해 인터넷을 통하여 정보를 수집한 후에 그 내용을 재구성하여 홈페이지를 구축한 후 실험수업을 실시하였다. 실험수업의 결과 전통적인 수업반보다 인터넷 홈페이지를 활용한 수업반 학생들의 학업성취수준이 훨씬 높게 나타났다. 한편 인터넷 홈페이지를 활용한 실험수업밥의 겨우 구조적 수업반에 비해 비구조적 수업반 학생들의 학습성취도가 더 높게 나타났으나 그 차이는 유의적이지 않았다. 또한 수업 흥미도, 만족도, 학습의욕 등에도 실험반 학생들은 상당히 긍정적인 평가를 보였다. 본 연구를 통해 지리수업의 학습효과를 높이고 학생들의 흥미도를 높이기 위해서는 인터넷을 활용하는 수업형태가 바람직하다는 결과를 도출하였다. 특히 본 연구를 통해 앞으로 학생들의 학업성취도와 흥미도를 높이기 위해 인터넷을 수업에 활용하는 교수-학습설계의 개발이 필요함을 보여 주었다.

General education is changed by accepting the change in education environment to digital generation, emphasis about student-centered education, and change of teacher's role. E-learning has taken center stage as an effective learning environment but the problems are drawn for the absence of interaction that is important in learning. In this study, on the basis of questionnaire results about learning using website, we operated blended-learning where students come and go in cyberspace and physical space to set up the lesson environment for emphasizing interaction. We selected a control group (N=40) and an experimental group (N=40) from second grade students in a middle school for this research. General instructor-led lessons were implemented in the control group and blended-learning lessons to emphasize interaction between teacher and students were implemented in the experimental group. The experiments were applied to eight class-hours in 'characteristics of matter' unit. We implemented Test of Science Related Attitude (TOSRA) to the students before and after the lessons and administered questionnaire for checking attitude changes and perception in students. The results of the test show that the experimental group students were more encouraged and became more confident and curious about scientific learning than the control group students. The analysis of the interview and results of TOSRA show that blended-learning provided guidance and feedback by the teacher to the experimental group students more than the control group students. Blended-learning is suggested as a learning-method that is helpful in improving scientific attitude in students because it enables them to express their experiences without limit of time-space and promote interaction between teacher and students.

The purpose of this study was to examine the effects of formative assessment with detailed feedback on students' science achievement, attitude, and interactions between the teacher and the students. For the study, 133 seventh graders were selected from a girl's middle school in Seoul, and assigned to the experimental and the control groups. The duration of the treatment was over a period of nine weeks. In the experimental group, detailed feedbacks on the solution, teacher's comments on the results, and relevant references were provided after each formative assessment. However, only the answers were presented in the control group. Prior to instructions, a achievement and a attitude tests were administered. After the instructions, follow-up tests which were similar to the pretests were also administered. The results showed significant difference between the two groups in science achievement. It was found that the usage of formative assessments with detailed and supportive feedbacks was more effective in stimulating students' interest, raising their confidence in the subject, increasing their participation, as well as reducing their anxiety. The results also strongly indicated that detailed feedbacks were more effective in improving the interactions of the teacher and the students. The results strongly suggest that formative assessment utilizing detailed and supportive feedback is a necessary component of effective science teaching and learning.

현재 진행되고 있는 수준별 수업에서 교사들이 직면한 가장 큰 문제 중에 하나가 수준별 평가에 관한 문제이다. 교육내용을 3단계(상${\cdot}$중${\cdot}$하)로 나눌 경우 평가의 단계도 3단계로 나누는 것이 이상적이다. 하지만 실제로 학교현장에서는 가르친 내용과 평가가 불일치하는 경우가 있으며 이러한 수업과 평가의 불일치가 심화반 및 보충반 학생들 모두에게 학습의욕을 저하시킬 수 있다. 따라서 본 연구에서는 수준별로 나누어 학습한 학생들을 수업에서 가르친 내용과 근접하게 평가하는 방안을 연구하였다.

This study is to propose a communication strengthening teaching model using action learning for Spanish learners, and to verify its effectiveness through a case study of Spanish lessons. This study was conducted under the same conditions by dividing 91 students from September 1 to December 20, 2019 into experiment and control classes. As a result of the experiment, both classes improved their writing ability to some extent, but the learners in the experimental class applying action learning showed more meaningful results in terms of the content, expressions, fluency of the text, and the affective domain test also showed a significant difference. The development of this teaching model, which is necessary for learner-centered convergence activities, is expected to be of academic significance as it can be used for other foreign language class activities as well as improving Spanish communication.
