The purpose of this study was to provide fundamental data and implication for forming desirable viewpoint of mathematics lesson critique and for improvement of expertise in lesson by compare and analyze the viewpoint of mathematics lesson critique of pre-service and in-service teachers. For the achievement of the purpose, The lesson critique materials of each 25 pre-service and in-service mathematics teachers were collected and arranged, and compare and analyze the viewpoint of mathematics lesson critique of pre-service and in-service teachers by using the standard for analyzing viewpoint of lesson critique composed of two categories, five main codes and 18 sub codes. The results of this study, both pre-service and in-service teachers have tendency for criticising lesson focusing on the practice rather than plan of lesson and both pre-service and in-service teachers showed evaluative reaction in most of critical statements and used positive ones rather than negative ones. The only pre-service teachers, though minor of them, showed non-evaluative reaction in criticising class and most of the statements were just description and explanation without any their own judgement for the scenes and activities of lessons and most of pre-service teachers have tendency to include reflection and introspection for their own class in lesson critique.

This study is to ascertain pre-service teachers' conceptions for the causes of season change, to verify their conceptional mistakes, and to analyze how their conceptions are changed while presenting Disproof-Experiment Model where they cannot explain it with their current conceptions. 32 junior students of Education universities, pre-service elementary teachers, located at the middle of Korea participated in this research including two interviews and one experiment activity. As a result of analyzing of the data, the pre-service teachers held diverse conceptions for the causes of season change such as to mistake the phenomena, the distance between the earth and the sun, the tilting of the rotation axis and the revolving around the sun while changing the tilting direction of the rotation axis as the cause. After applying Disproof-Experiment Model designed by the researchers in order to change the current conception above, the conception changes of the pre-service teachers were investigated. Diverse Disproof-Experiment Models were used differently depending on the pre-service teachers' conceptions. As a result of the application of Disproof-Experiment Model, 26 out of 28 pre-service teachers were changed to scientific conceptions. It was determined that in order to modify pre-service teachers' conceptions, designing and presenting the Disproof-Experiment Model appropriate to their conceptions are effective after analyzing their conceptions. In case of conceptions that pre-service teachers feel difficult, it was established that unraveling experiment models prescribed after investigating the preconceptions and identifying the misconceptions are important.

The purpose of this study was to explore strategies used by pre-service elementary science teachers in planning a science lesson. The participants were six senior students from a national university of education located in the midwestern area of Korea. Data regarding their planning strategies were gathered through both thinking-aloud and observation. Research findings suggest that: three of the teachers had little understanding of the necessity of reviewing unit contents or prior learning for planning a science lesson; five student teachers relied heavily on learning objectives presented in teachers' guidebooks without considering their appropriateness; all teachers exhibited an intention of composing different activities or teaching approaches from teachers' guidebooks; only two teachers thought about learners' prior knowledge or understanding levels; five and three teachers had poor understanding of discovery learning models and importance of teacher's questioning, respectively; and five teachers paid little attention to assessment.

This study used questionnaires to investigate how pre-service elementary teachers understand ocean acidification. As a result of gender, female teachers were more aware of ocean acidification than male teachers, but male teachers had a higher average rate of correct answers, with a lower standard deviation. Teachers from the natural sciences knew more about ocean acidification than did teachers the liberal arts. Teachers ranked environmental crisis in order of most dangerous to least dangerous as follow: global warming and the greenhouse effect, ozone depletion, ocean acidification, and acid rain. About 46.7% of teachers learn about ocean acidification through education, followed by broadcasts, school lectures and the internet. The educational materials most desired for teachers were videos related to ocean acidification. Pre-service elementary teachers have two broad perspectives on ocean acidification. Firstly, they refer to economic loss and food shortages, and secondly, they note that there is a need for improved awareness and publicity about ocean acidification. The role of elementary school teachers is important because their awareness of environmental issues has a considerable effect on teachers perception of the environment. Revitalizing education on ocean acidification and government support are necessary to effectively communicate the seriousness of ocean acidification. Lastly, we need to study ocean acidification in detail so as to be able to persevere toward protecting our ocean ecosystem.

수학 교육에서 교사의 SMK와 PCK에 대한 역량은 대단히 중요하다. 그들의 SMK와 PCK에 대한 현황 파악과 그에 따른 강화방안이 있다면 더 없이 좋을 것이다. 그러나 교사를 대상으로 교수 역량 강화에 대한 연구를 수행하는 것은 현실적으로 많은 어려움이 있다. 이에 본 연구에서는 23명의 예비 초등교사를 대상으로, 이들의 SMK와 PCK에 대한 현황 파악과 그에 따른 강화방안으로 DGE 탐구활동을 활용하였다. 그 결과 3명의 예비 초등교사가 초기 SMK에서 오류를 나타내었으며, 초기 PCK에서는 설명 및 시각적 확인 위주의 교수 방법으로 문제해결에 필요한 성질을 지도하는 것에 중점을 두었다. 또한 DGE 탐구활동의 실제는 역동성 개념 이해 및 구현의 어려움, $75^{\circ}$ 작도에 집착 및 결과의 일반화, '접는 활동'의 수학적 해석의 어려움, 무난한 GSP 구현의 네 가지로 분류되었다. 이후 초기 SMK에서 나타난 하나의 오류가 수정되었으며 PCK의 방법적 측면에서 GSP를 활용한 시각적 확인이 추가되었다. 이러한 결과로부터 DGE가 예비교사의 SMK와 PCK 강화 도구로 활용될 수 있도록 돕는 몇 가지 교수학적 시사점을 추출할 수 있었다.

The purpose of this study is to consider pre-service and in-service elementary school teachers' beliefs about STS (Science-Technology-Society), by investigating their opinions on STS interactions. 222 of the seniors in Jinju National University of Education, namely pre-service elementary school teachers, and 185 of the active teachers in Kyung-Nam Province were selected as the objects for researching these matters. Their beliefs about STS interactions were examined. The results were analyzed with a percentage as an examining tool of TBA-STS(Teachers' Beliefs about Science-Technology-Society). The results were as follows; First, on the nature of science, most of them showed simple opinions. On the nature of technology, most of them also showed simple opinions. most of them recognized the interactions among science, technology, and society affirmatively. They showed simple opinions on the interactions between science and technology. In fact, they didn't recognize the interactions between science and society, but they knew the influence of technology on society relatively concretely. Second, if one consider the cognitive situation or the distributing route of STS, he can easily find that most teachers never or little know it. At present, pre-service teachers learn STS from the lectures in their universities, and in-service teachers get information about it from science magazines/newspapers and training.

After pre-service teachers become teachers, traditional patterns of classroom discourse which they had experienced as students affect their classroom discourse implicitly. For this reason, it is needed to get a new insight for evaluating and reflecting a teacher's classroom discourse. In this study, I analyzed the information flow of science classes of pre-service elementary school teachers. The finding showed that teachers' organizational skills for students' information made advanced science classes by maintaining discourse cohesions. And the findings also showed a way how to analyze, evaluate or reflect science classroom discourse. This trial could contribute to find out the characteristics of teachers' science classroom discourse and show the directions to them how to change their classes beyond impressionable evaluations for their science classes.

The purpose of this study was to gain a suggestion how to educate pre-service elementary teachers in science education. One hundred and twenty three students were involved in the questionnaire to investigate the perception of science. Many of pre-service elementary teachers had a negative image of science. They consider science to be stiff, inflexible and dull. They suggested much more of foreign scientists than Korean ones as respectable scientists. They are very interested in science related to society, and themselves. It is necessary for elementary pre-service teachers to be educated to positively improve the images of science and scientist, and to understand modern scientific philosophical perspectives. And, Korean scientific history education should be educated formally or informally for them to count on about Korean scientists as respectable ones in science education.
