이 연구에서는 중등 예비과학교사의 수업 계획의 특징과 이에 영향을 미친 요인을 조사하였다. 서울 소재 사범대학에 재학 중인 13명의 예비과학교사가 연구에 참여하였다. 예비교사들이 작성한 교수학습 지도안과 활동지 등의 교수학습 자료, 수업 계획 일지를 수집하였으며, 수업 계획의 요소별로 예비교사들의 수업 계획에 대한 심층적인 정보를 얻기 위해 반구조화된 면담을 실시하였다. 연구 결과, 대부분의 예비교사들은 차시 계획에만 초점을 맞추어 교육과정을 체계적으로 고려하지 않았다. 수업 목표는 수업 계획에서 부차적인 요소로 간주되었으며, 주로 인지적 측면에만 초점을 맞추어 기술되었다. 교수학습 전략을 구체화하는 것은 수업 계획의 출발점이 되었는데, 예비교사들은 자신의 중등학교에서의 학습 경험을 반성적으로 평가하는 과정을 통해 예비교사 교육과정에서 학습한 구성주의적 교수학습 이론을 수용하여 수업 계획에 활용하였다. 교수학습 활동으로 실험 활동을 계획한 경우에는 교과서에 수록된 실험 활동을 그대로 사용하는 경향이 높았으나, 실험 외의 활동은 자신의 개인적 경험에 의존하여 계획하는 것으로 나타났다. 또한, 예비교사들은 교수학습 평가를 수업 계획의 요소로 인식하지 못하여 이를 계획하지 않는 경우가 많았다. 이러한 결과를 바탕으로 중등 예비과학교사 교육에서 수업 계획에 대한 구체적인 교육 방안을 제안하였다.

This study is to verify the effects of classes at a finishing stage using cartoons depicting certain science textbook units on scientific attitudes and academic achievements of students, compared to those of classes using experiment and observation oriented textbooks. Participants of this study were 56 fifth graders at B Elementary School in Busan, and cartoon textbooks were developed based on 'Unit 1. Mirror & Lens' and 'Unit 3. Temperature & Wind' from a science textbook for the 1st semester, the year 5 to conduct cartoon led lessons just before ending a class till the 10th lesson, for the period of 4 weeks. The result of this study can be summarized as follows: Firstly, scientific attitudes improved better from the cartoon based lesson of a final stage than from the experiment and observation method, and especially more effective in lower groups among all other academic achievement levels as well as in male students. Secondly, academic achievements scored higher when cartoons were used in lessons than when the experiment and observation type was used, with higher groups of academic achievement levels working better, despite no significant gap existing between two genders. Thirdly, the memory transfer and sustenance of lessons were more effective in finishing class stage with cartoon studies than with experiment and observation one, and among all levels and both sexes, higher academic groups and male pupils exceeded. Fourthly, when questioned about their opinions on a cartoon led lesson for a final stage, 65% of those participants responded positively, while higher groups preferred more than lower groups. responded positively, while higher groups preferred more than lower groups.

The purpose of this study is to figure out how teachers conduct an experiment in measuring the size of the Earth and how students recognize it. For this study, an in-depth interview was conducted one week after the lesson on the experiment about measuring the size of the Earth. The participants were five secondary school teachers and five secondary school students. The in-depth interview was recorded and transcribed. The result of the interview was drawn through an inductive categorized analysis method. As a conclusion of this study, the teachers taught the students the lesson using alternate angles instead of using the altitude of the Sun. Their lessons were based on Eratosthene's story or some related illustrations suggested in the textbook and not based on an explanation of the principle. Also, students measured the Earth's size only by using alternate angles and didn't understand the meaning of the shadow in the experiment. The results of this study show that teachers need to reconstruct the textbook and understand the accurate experimental principle for the students to have a meaningful experience of the experiment on measuring the size of the Earth.
