The purpose of this study is to examine the effects of the Portfolio applied science instruction on the students' scientific affective domain and perceptions of portfolio in elementary schools. Portfolio applied science instruction of the 6th grade science unit 'Environment pollution and Nature protection' was developed for this study. Traditional instruction was implemented to the control group and portfolio applied science instruction was implemented to the experimental group. Pretests of the scientific affective domain were administered to both groups. The treatment was given for about seven weeks for both groups. Instruments about scientific affective domain were administered to both groups. A questionnaire on perception of portfolio applied science instruction was given to the experimental group after the treatment. The results were analyzed using t-test on the students' scientific affective domain. The results of this study are as follows: 1. Portfolio applied science instruction program for elementary schools was developed. Students themselves determine the portfolio learning goal in a portfolio applied science instruction. Students construct the portfolio and they evaluate themselves and other colleagues. Also teachers go on portfolio applied science instruction considering portfolio purpose, concepts, evaluation. 2. There was not a statistically meaningful difference between an experimental group and a control group o]1 the students' scientific affective domain. In three sub categories of a scientific affective domain, the science perception, the interest on science and scientific attitude, there were not statistically meaningful difference among them. 3. As the results of the questionnaire on perceptions of portfolio, they didn't understand it very well but after learning portfolio, they showed positive attitude to perceptions of portfolio. Students in portfolio applied science instruction like more the portfolio applied science instruction than general instruction. 4. Portfolio applied science instruction has an useful value as a method of teaching and evaluation. Students and teachers can produce various portfolios products in portfolio applied science instruction. As a conclusion, portfolio applied science instruction was not statistically meaningful on the students' scientific affective domain, but it gives positive effects on perceptions of portfolio in elementary schools. Therefore, portfolio has an educational value as a method of teaching and evaluation for students' growth. In the future, teachers and students must have interaction and feedback in portfolio applied science instruction.

The purpose of this study was to explore preservice elementary teachers' perceptions on models used in science and science education. Participants were sixty-one undergraduate students who were enrolled in a science education course offered at a university of education located in a mid-sized city, Korea. Data were obtained from the participants at the beginning of the course when they provided their answers to a questionnaire about models. The analysis revealed that a large number of the preservice teachers perceived models as representative of physical realities. By contrast, a relatively small number of them viewed models as representations of ideas or things like theories or hypotheses. Lots of the participants were apt to define a model from the perspective of its functions and considered the purposes of models communication, teaching, and understanding as well as visualization, simplification, and clarification. Most of the preservice teachers believed that there could be multiple models for a single target, and all of them answered that models could be changed in science. It was therefore concluded that the preservice teachers perceived properly the multiplicity and variability of models. Nevertheless, they could not elaborate how a model is used and evaluated in the process of scientific inquiry, and just a few of them mentioned the detailed nature of models. The preservice teachers possessed teacher-centered views of using models in the science classroom, and a small number of them remarked that they were going to use models for students to develop their own models and perform scientific inquiry.

This study examined how pre-service elementary teachers' perceptions regarding the learning environment (learning focus/ability-meritocracy/cooperative climate) and achievement goals (mastery/performance-approach/performance-avoidance) in science education courses jointly contributed to their science teaching efficacy beliefs (personal science teaching efficacy belief/science teaching outcome expectancy). A path analysis supported a causal model in which the perception of the learning focus influenced the mastery goal, which in turn influenced the personal science teaching efficacy belief and science teaching outcome expectancy. The perception of learning focus also had a direct effect on science teaching outcome expectancy. The perception of ability-meritocracy influenced personal science teaching efficacy belief via the performance-approach (positively) or, conversely, the performance-avoidance goal (negatively). No link .was deduced from the perception of cooperative climate. The educational implications of these findings were also discussed.

This study was conducted among elementary pre-service teachers who participated in creative story writing exercises related to science. It aimed at analyzing their perceptions, based on their own experiences in the story writing exercises, about story writing as a pedagogic method, to discover the implications on science education. First, creative story writing exercises were carried out over a period of eight weeks by 114 elementary pre-service teachers at a college of education, all of whom were non-science majors taking a course on earth science as a liberal arts elective. Afterward, an open-ended survey was conducted among them to discover their attitudes and opinions, both as students and as teachers-to-be. The majority of the subjects expressed a positive opinion about creative story writing as a pedagogic tool, stating that they would apply it in their future teaching by telling stories they wrote or having students write their own compositions. Pre-service teachers conclude a creative writing improves students' studying, leads interest and motivation. In addition, it linked with daily life and other school subjects. Creative story writing, when used at colleges of education, has didactic value as an empirical exercise for pre-service teachers who are not majoring in science.

서울 시내 22개 중학교에서 131명의 과학 교사를 대상으로 비유 사용 실태와 비유 사용에 대한 인식을 조사하였다. 대부분의 과학 교사들은 과학 수업에서 비유를 자주 사용하였고 비유의 효과에 대해서 매우 긍정적으로 인식하였다. 비유를 사용할 때에는 관련된 그림을 함께 제시하고, 비유 자체에 대하여 설명하고, 잘못 생각하기 쉬운 것도 언급해야 한다는 데 동의하였으며, 실제 수업 시간 중에 그렇게 한다고 응답하였다. 그러나 하나의 개념을 여러 개의 비유로 설명하거나 학생 스스로 비유를 만들도록 하는 것은 잘 이루어지지 않는 것으로 나타났다. 또한, 과학 수업에서 비유가 효과적으로 사용되기 위해서는 적절한 비유 자료와 체계적 비유 사용 수업 모형이 필요하다고 생각하였다. 한편, 석사 이상의 학위를 가진 교사 들이 비유 자체에 대해 더 많이 설명하였고, 비유 사용상 보완점과 비유 사용 전략의 필요성에 대해 더 긍정적으로 인식하였다. 과학 수업 및 학생 활동에 대하여 현대적 인식을 가진 교사들이 고전적 인식을 가진 교사들에 비하여 비유를 많이 효과적인 방식으로 사용하였다.

The purpose of this study was to investigate the effect of the 'Chemistry and Experiment' course employing the Small-Scale Chemistry(SSC) experiment on the 30 pre-service elementary teachers' attitude toward laboratory work and their science teaching efficacy. This study also examined the perception of the pre-service elementary teachers about the SSC experiment. In the result, there were found significant interactions between the treatment and prior level in attitude toward laboratory work. The attitude toward laboratory work of low-level pre-service teachers was improved while that of high-level pre-service teachers remained unchanged. However, there was no significant change in their beliefs regarding science teaching efficacy. Through the analysis of questionnaire, it was also found that they had positive perceptions about the SSC experiment, and most of them as pre-service teachers found the SSC experiment helpful to teach chemistry experiments.
