The necessity of this study was to improve academic achievement and math attitudes through leveled reciprocal peer learning, and the specific purpose was as follows. First, each unit seeks to select learning methods and contents for each level of class for reciprocal peer learning, second, develop activity sites for each level through curriculum analysis, and third, improve academic achievement and math attitudes through classes that apply reciprocal peer learning activities. The study was conducted on 60 second graders of 00 High School in 00 Metropolitan City. Two classes were selected for the midterm exam results for the first semester of the second grade. Class 1 was divided into the experimental group and the other class 1 was divided into the comparative group, and 13 classes were conducted for about 2 months from May 1 to July 4, 2020. The experimental group (30 students) was a class that applied leveled reciprocal peer learning activities, and the comparative group (30 students) was a class that was taught based on traditional textbooks. As a result of this study, first, in this study, it was possible to improve academic achievement and math attitudes by setting learning contents for each unit and applying reciprocal peer learning activities for each level. Second, the experimental group taught by applying leveled reciprocal peer learning activities was effective in academic achievement and math attitudes compared to the comparative group taught based on traditional textbooks to students in the upper, middle, and lower groups. Third, in the class applying leveled reciprocal peer learning activities, low-level students who were neglected in math classes were also interested in the class and actively participated in it, showing improvement.

본 논문에서는 SCORM을 기반으로 한 e-Learning 시스템에서 학습자의 학습 활동을 트래킹하여 학습자의 수준을 적응적으로 판단하는 기법을 제시하였다. 제시된 기법에서는 모집단의 크기가 작을 경우 교수자가 지정한 난이도를 이용하여 학습자의 수준을 판단하고, 모집단의 크기가 충분히 클 경우에는 문항반응이론을 적응한 난이도에 의해 학습자의 수준을 판단하였다. 문항반옹이론을 적용할 시점에서 교수자가 지정한 난이도가 문항반응이론에서 추정한 난이도와 차이가 날 경우, 교수자가 지정한 난이도를 문항반응이론의 난이도로 수정하는 적응적인 기법을 제시하였다. SCORM의 트래킹 기능을 이용하여 실험한 결과 문제를 푼 학습자의 수가 적을 경우에는 학습자 수의 변화에 따라 학습자의 수준이 계속 바뀌는 문제점이 있음을 알 수 있었다. 따라서 모집단의 크기가 작을 경우, 본 논문에서 제안한 방법에 의해 교수자가 지정한 문항의 난이도를 이용하여 학습자의 수준을 판단하는 것이 효과적이었다.

This study quantitatively investigated the actual situations and perceptions of gifted students and their teachers during small group inquiry activities in Korea. Some 1,670 gifted math students and 1,732 gifted science students as well as 614 of their teachers were selected through random sampling to participate in this study. Data were collected by means of a survey developed by the researchers of this study, based on reviews of literature related to inquiry and small group cooperative learning. The results were as follows: (1) In Korean gifted education, small group inquiry activities were frequently used as teaching and learning strategies, and both the students and teachers perceived its effects to be very positive in terms of cognition and affection. (2) Gifted education teachers emphasized the development of students' procedural inquiry skills as well as logical thinking skills, whereas they were indifferent to the essential elements of small group cooperative learning and therefore the lessons did not surpass the level of traditional group activities. (3) The fact that the actual small group inquiry activities did not reflect the characteristics of well-organized small group activities is due to a lack of knowledge on the teacher's part as to effective teaching strategies concerning cooperative learning. This study implies that gifted education teachers require the opportunity to reflect on and develop their knowledge and understanding of small group inquiry activities through professionally developed programs in order to maximize the effectiveness of small group inquiry activities in gifted education.

This study is the result of the operation of Project-Based Leaning (PBL) conducted at S Women's University's Teaching and Learning Center. This study investigated the learning outcomes and learning satisfaction of participating learners. The questionnaire for this study consisted of a total of 28 questions on learning strategies (peer learning strategies, critical review strategies, elaboration strategies, super cognitive, and online project activities) and learning satisfaction. For the survey, 300 students (first semester: 210 students, second semester: 90 students) participated in the 2020 project-based learning. As for the pre and post questionnaire results, the average of the post questionnaires of the first and second semesters was higher than pre-questionnaires result. After taking project-based learning in the first and second semesters, the average of learning strategy and learning satisfaction improved. It was confirmed that the project activities are helpful in learning activities and increase participation in class. Based on this, it implies that in-depth PBL research in a non-face-to-face learning environment should be continued.

In this study, we investigated the characteristics of lesson planning of pre-service secondary science teachers and the factors which influenced in their lesson planning. Thirteen pre-service secondary science teachers at a college of education in Seoul participated in this study. Teaching-learning materials such as lesson plans and handouts, and lesson planning journals written by the pre-service teachers were collected. Semi-structured interviews were also conducted to obtain information about their lesson planning activities. The analyses of the results revealed that most of the pre-service teachers did not systematically consider the national science curriculum and focused on planning one lesson only. Instructional objectives were not only considered as minor element in lesson planning, but also limited to cognitive domain. Devising teaching-learning strategies was found to be the starting point of the lesson planning. They accommodated constructivistic teaching-learning theory presented in their method courses through reflective evaluation of the experiences of learning in their secondary schools. The experiment activities that were presented in the textbooks were used themselves when they planned experiments as student activities, but other activities were planned depending on their personal experiences. Most pre-service teachers did not plan assessment because they could not recognize it as an element of lesson planning. These results may offer some implications in educating pre-service secondary science teachers on lesson planning.
