  • This study is intended to develop plant inquiry instruction using Rapid-cycling Brassica rapa (RcBr) whose life cycle is relatively short, and to apply it to the elementary science instruction of the 4th grader and examine their plant concept, science inquiry skills and science-related attitudes. The materials were consisted of laboratory manuals for the students as well as teachers' guide. By observing the life cycle of RcBr, students can experience the conceptual learning of the plant's life cycle. In addition, this study investigated the cause of change in science inquiry skills and science-related attitudes by interviewing 12 students. It has shown that plant inquiry instruction using RcBr has meaningful effects on students' understanding of the plant concept, improving students' science inquiry skills, and changing students' science-related attitudes. Students who showed improvement in science inquiry skills were able to answer questions regarding science knowledge correctly. And students whose science related attitudes were improved had a positive attitude on cultivating RcBr. Students told that RcBr was an interesting and good material to inquire plant. Because of its small size and its relatively short life cycle of RcBR, it should be a desirable plant material for the inquiry instruction which can give rise to useful and meaningful results for the elementary school students.

  • This study is aimed at exploring the effects on Science Inquiry Ability, Scientific Attitude and Science Achievement of the Elementary School Students according to the Input time of Web-Based Instruction Programs. As the object of the study, seventy-two students were selected from three classes in the fifth grade of Y Elementary School located in the city of T, Gyungsangnam-do. They were classified into the three groups such as Group A (Class 1), Group B (Class 2) and Group C (Class 3). The author threw web-based instruction programs into the begining of a unit, during a unit, the end of a unit to each group, and explored the effects. The results of this study were as follows: First, for the learning effect of science inquiry ability, it was indicated that there was the highest effect in the case of throwing web-based instruction programs into during a unit, but the effect reduced a little in the case of throwing them into the end of a unit. Secondly, the scientific attitudes tended to be reduced in the case of throwing them into during a unit, but there did not occur statistically significant improvement. Thirdly, the degree of improvement of the science achievement tended to be highest in the case of throwing them into the end of a unit. Such findings indicated that the time of throwing in web-based instruction programs affected science inquiry ability, scientific attitude and science achievement of elementary school students. Thus, it will be said that teachers need to teach their students with the class strategies of considering various scientific elements revealed at the time of throwing in web-based instruction programs.

  • 이 연구의 목적은 고등학생들의 독창적인 문제발견 능력과 과학 학업 성취도, 과학 탐구능력, 창의적 성격 사이의 관계를 알아보는 것이다. 발견된 문제의 독창성을 평가하기 위해 빈도수에 의한 평가와 교사와 학생에 의한 주관적 판단에 의한 평가 방법을 사용하였다. 그 결과, 세 가지 평가 방법은 큰 차이가 없었으나, 빈도수에 의해 평가할 경우 친숙한 문제가 더 높은 점수를 받을 가능성이 있는 것으로 나타났다. 또한 전체 학생들의 독창적인 문제발견 능력은 학업 성취도 및 창의적 성격과 정적 상관이 있었으나, 과학 탐구능력괴는 상관이 없었다. 그러나 독창성 점수가 높은 상위 집단에서는 창의적 성격과 정적 상관이 있었으며, 하위 집단에서는 학업 성취도와 정적 상관이 있었다. 또한 독창성 점수가 높은 상위 집단과 하위 집단 간의 과학 탐구능력과 창의적 성격은 유의미한 차이가 없었으며, 학업 성취도는 물리I과 화학I 과목에서만 유의미한 차이가 있었다. 앞으로 문제발견 능력을 평가하기 위한 평가 방법에 관한 연구와 함께 독창적인 문제발견 능력에 영향을 미치는 다양한 변인에 대한 연구가 수행되어야 할 것이다.

  • The purpose of this study was to identify concretely how to improve inquiry learning. To put the purpose in detail : 1) to define the inquiry skills 2) to select the factors of inquiry skills appropriate to the content of Science I (earth science) textbook 3) to develop items which consist of experimental inquiry and concept inquiry in due proportion, to evalute inquiry skills 4) to analyze the relationship between high school students' cognitive levels and the achievement of science inquiry skills. To achieve these objectives, the investigator sampled 558 students in eleventh grade, living in Seoul, Chung-Ju and Kwang-Ju, and evaluated their cognitive levels and the achievement of science inquiry skills. The results of this study showed that the cognitive levels of students were lower than those identified in Piaget's work and that the achievement of science inquiry skills were low also. It may be thought that one of most important reasons to bring about those results is lacking in adaptation capability of science inquiry items and inquiry learning. So, it can be recommended as a way to heighten cognitive levels to make inquiry learning using the textbook content. In conclusion, the investigator make suggestions as follows : 1) to give inquiry learning which consist of experimental inquiry and concept inquiry in due proportion 2) to develop inquiry items to include content for evaluating inquiry learning, and test items for psycho-motor areas 3) to publish textbooks which motivate students' inquiry activities and develop their creative thinking, considering students' cognitive levels and inquiry skills.

  • We have investigated the effects of participation in science fairs on perception, science related attitudes and science inquiry process skill of thirteen fifth-grade elementary school children in the science subjects. Questionnaires were prepared to find out student's reactions to the participation in science fairs. All participated children responded that the activities at the fairs were interesting and helpful to learning scientific knowledge and inquiring scientific questions. From the analysis of the responses we have found that the participation process including preparatory ones during the fairs may help children to enhance their science related attitudes and science inquiry process skill and can be considered as a useful science curriculum.
