This study investigated the influences of reciprocal peer tutoring (RPT) strategy on middle school students' science achievement, self-efficacy, perception of instruction by grouping method and science achievement level. Eighth graders from a middle school in Seoul were assigned to comparison, homogeneous RPT, and heterogeneous RPT groups. The students were taught about 'separation of mixtures' for 8 class hours. After the instructions, a science achievement test consisting of three subtests (knowledge, understanding, and application), a self-efficacy test, and a questionnaire about the perception of instruction were administered. The analysis of the results revealed that the scores of heterogeneous RPT group, regardless of the students prior science achievement level, were significantly higher than those of the other groups in the knowledge and understanding subtests, and the self-efficacy test. The scores of homogeneous RPT group were significantly higher than those of the comparison group in the knowledge subtest but not in the understanding subtest and the self-efficacy test. The low-level students in heterogeneous RPT group performed better in the science achievement test and the application subtest than those in the other groups. The high-level students in RPT groups performed better in the science achievement test than those in comparison group. However, there was no significant difference for the application subtest scores of the high-level students of the three groups. Most students in RPT groups perceived positively on the instructions. The students in heterogeneous RPT group and low-level students especially showed more positive perception of the instruction than those in homogeneous RPT group and high-level students.

교수-학습 방법 발전이 필요하다는 논리와 관련해서 선진국들의 교육 추세를 눈여겨볼 필요가 있다. 첫째, 교육이라는 행위가 교사가 주도하는 교수(teaching, instruction)로부터 학생이 주도하는 학습 (learning)으로 바뀌어 가는 추세이고, 둘째, 학습에 있어서 자극-반응 모델에 기초한 반응에는 강조를 두지 않고 인지(cognition), 즉 지각과 사고를 강조하고 있는 추세이며, 셋째, 따라서 학생이 학습을 제대로 해 가는 데 필요한 여러 가지 방략(strategy), 가령 구성적 방략이나, 비고츠키 모델 등이 개발되거나 원용되고 때로는 기존 방략들(탐구적 방법, 문제해결 방법 등)이 재 강조되면서, 그 방략들이 학생들에게 유효하도록 가르쳐 지고 있는 실정이다.(중략)

The current study investigates how student-teacher interaction can be developed through task-based teaching in undergraduate students' Saudi teaching and learning context. An experiment was conducted for five weeks on 85 male undergraduate students at a Saudi public university based in Jeddah, Saudi Arabia. The study investigated different types of student-teacher interaction through task-based teaching (speaking activities). The results revealed that the experimental group (43 students) evinced much more enthusiasm, willingness, engagement and readiness in their inclass participation than their peers in the control group (42 students). The student-teacher interaction also helped students to be more responsive to general and specific topics in speaking activities. The study recommends that decision-makers in education make student-teacher interaction part of the student's monthly assessment. It also recommends that more efforts be made to foster the awareness of students, teachers, and parents awareness of the academic and non-academic importance of interaction. One final recommendation of the research is that student-teacher interaction should be more emphasized and integrated into the school curriculum and adopted as a critical teaching strategy.

The purpose of this study was to investigate the instructional effect of a four-stage problem solving approach visually emphasizing the molecular level of matter upon students' conceptions and problem solving ability. On the basis of the research results regarding molecular representation in learning chemistry, problem-solving instruction, and the effect of visual materials, the instructional strategy was developed while considering Korean educational situations. The treatment and control groups (2 classes) were selected from a girls' high school in Seoul and taught about stoichiometry, gas, liquid, solid, and solution for 13 weeks. For the treatment group, 52 charts were supplied in order to emphasize the molecular level of matter and/or 4 stage problem solving strategy-understanding, planning, solving, and reviewing. For the control group, traditional instruction was used. Before the instructions, the Group Assessment of Logical Thinking and the Spatial Ability Test were administered, and their scores were used as covariate and blocking variable, respectively. After the instructions, students' conceptions and problem solving ability were measured by the Chemistry Conceptions Test (CCT) and the Chemistry Problem Solving Ability Test (CPSAT), respectively. The results indicated that the CCT scores of the treatment group were significantly higher than those of the control group. The students in the treatment group also exhibited less misconceptions than those in the control group. However, there was not significant difference for the CPSAT scores. No interaction with students' spatial ability was found for both students' conceptions and problem solving ability. Educational implications are discussed.

This paper focuses on proportional reasoning being emphasized in today's elementary math, and analyzes the way students use their proportional reasoning abilities and strategies according to their academic achievement levels in solving proportional problems. For this purpose, various types of proportional problems were presented to 173 sixth-grade elementary school students and they were asked to use a maximum of three types of proportional reasoning strategies to solve those problems. The experiment results showed that upper-ranking students had better ability to use, express and perceive more types of proportional reasoning than their lower-ranking counterparts. In addition, the proportional reasoning strategies preferred by students were shown to be independent of academic achievement. But there was a difference in the proportional reasoning strategy according to the types of the problems and the ratio of the numbers given in the problem. As a result of this study, we emphasize that there is necessity of the suitable proportional reasoning instruction which reflected on the difference of ability according to student's academic achievement.

Widespread recognition of the various aspects of science education has been prompted by post-positivist philosophers' discussions of the nature of science and intense debates among constructivist psychologists about learning in science. Their discussions and debates, in turn, have raised the problems associated with teaching/learning of science in the schools. The purpose of this article, basically based on the reviews and analyses of the literature related to philosophy of science and psychology, was to describe the implications of post-positivism and constructivism for current science education in the schools. In this paper, the author defines science education as education of/about science, and education through/by science. He also stresses that scientific literacy and decision-making should be emphasized as the goals of science education, that the ethical dimensions of science and technology must be included in science curriculum, that group discussion and/or cooperative learning are effective teaching strategy for science as interpreted by post-positivists and constructivists, and that the assessment should be focused on the degree to which cognitive structure has been changed through instruction in the school classrooms.
