This thesis intends to make a study on the effectiveness of Nursing Professors through perceptual psychological approach. Purpose of the Study Researches have been made relating teacher′s effectiveness measurement. However, they share a common defect that they have been done on the basis of superficial aspects of the problems aspects that can bi measured by general objective survey only, but this study is designed "to understand his behavior in terms of a human behaving and of a self as an instrument"-principle, based upon the Perceptual Psychology which puts more stress on the inner perception than on the external one. Method of the Study This thesis is based chiefly on the two sources : "Perceptual Orientation Scale"(Chunghoon Choy, 1971) which has been standardized on the basis of perceptual psychology and the question acres made by the researcher of this thesis and given to the 34 Nursing Professors in seoul and other country. Result of the Study The method of data operation by Pearson "r" asserts that there were distinct deep relation Between Perceptual orientation and fellow′s estimate, while a little relation among the estimate of a-administration, educational backgrounds and occupations but no relations the status of experiences. It can be concluded that the estimates between fellows working at "the same fields" have kept deep relations together on perceptual orientation which resulted from finding out a useful method to measure occupational effectiveness according to the perceptual field. Conclusion of the Study The personnel administration has been managed according to external flatus and not positive operation: on the other hand, this study holds, It shall be operated in accordance with the estimates by fellow, the "Preceptual Orientation Scale" for more positive ability. The study requires the following researches on the devoted professional occupations, such as medical doctors, teachers, nurses, etc. for the purpose of increasing their occupational effectiveness more scientifically.

The purpose of this study was to investigate changes in geological contents knowledge and self-confidence before and after the geological field trips. Fifty seven undergraduate students at a national university of education participated in this study. The questionnaires were developed by the researcher to serve the purpose. Findings were as follows. First, before and after the geological field trip, there was no significant difference in changes of geological content knowledge (p<.05). However, participants' self-confidence about the geological field trip changed significantly (p<.01). Second, there were no significant differences in changes of both variables in terms of gender (p<.05). And in this study, participants were grouped into two: science track that selected science areas and non-science track with social study selected in the college scholastic ability test. There were also no significant differences in changes of geological contents knowledge and self-confidence in terms of science or non-science track (p<.05). Third, in terms of the geological content knowledge, 24 pre-service teachers showed an increase, 12 students unchanged, and the 21 participants decreased. In contrast, per participants' self-confidence about the geological field trip, fifty three students indicated an increase with only one participant unchanged, and three preservice teachers decreased on the score. Finally, after the geological field trip, participants' comments indicated that they could feel the mystery of nature with the mind of a great experience. As a result, data showed that pre-service teachers became interested in geology, and motivated more in learning geological area than ever.

This study aims at identifying the effect of problem posing on the academic achievement in high school mathematics. As subjects of the study, two classes of first grade in high school were selected. One of them was treated with problem posing learning, the other was treated with learning-in-a-body. Each has 40 students and was also divided into two groups(high- level and low-level) according to their learning-level. Two instruments were used for this study. One was the teaching-learning method developed by the researcher. The other was TTCT(Torrance Test of Creative Thinking). The 't-test' was used for this study and the significant level of test was within 5 percent. The results of this study are as follows: 1. The group with problem posing learning showed significantly higher academic achievement(learning-ability) than the one with learning-in-a-body. 2. There was no significant difference in the academic achievement(creativity) between the two groups. But there was significant difference in the creative factors. 3. There was no significant differences in the academic achievement between high-level-groups in each group. 4. There was significant difference in the academic achievement (learning-ability) between low-level groups in each group. And there was significant difference in the creative factors. On the basis of the results above, the following conclusions could be made. The problem posing learning method was more effective in the academic achievement in highschool mathematics than learning-in-a-body. Especially low-level group was more effective than high-level group. These facts implies that it is more effective for a teacher to adopt the problem posing learning considering the students' learning-levels.

The purpose of this study was to find the relationship between elementary school teachers' beliefs of inquiry and science performance assessment. To collect data for analyzing elementary school teachers' beliefs of inquiry and their practice of science performance assessment, the researcher was surveyed with elementary school teachers by open-ended questionnaires and interview. The findings of this study were as follows; First, Most of elementary school teachers beliefs of inquiry was shown as constructivist tendency. This view of inquiry involves watching and doing experiments, and the skills of thinking processes, in which learners make their own interpretations rather than merely acquiring preexisting knowledge structures. Second, for content knowledge, participants' preception about the target of science performance assessment involved assessing application of science knowledge rather than basic level of substantive knowledge. For inquiry process, participants' preception about the target of science performance assessment involved assessing the lower level of inquiry rather than the higher level of inquiry. Most of participants was measured using a paper and pencil test for the actual evaluation methods due to the ease and objectivity of the assessment, the lack of understanding how to perform the performance evaluation process and method. Especially, participants who recognize that the higher level of inquiry was used performance and informal mode of assessing.

본 논문은 유전적 요소가 비슷한 형제 영재에 관한 사례연구이다. 본 연구자는 이들 형제가 3년간 이수한 영재교육원의 강사로 활동하면서 같은 과정의 수업시간에 나타난 두 형제의 상이한 수학적 성향에 관심을 갖고 두 형제의 자라온 환경과 부모의 기대, 양육태도 등 영재성에 영향을 주는 환경적인 요소 등을 연구 참여자와 부모의 면담을 통하여 비교 분석하였다. 부모는 일찍이 영재성을 드러낸 형에게 많은 기대와 지원을 한 만큼 강압적인 양육태도로 일관했으나 뒤늦게 영재성을 보인 동생에겐 자율적인 양육태도로 스스로 학습을 원하는 시기에 지원하였다. 그러한 결과 동생이 오히려 창의적인 사고와 학업 성취도에서 좋은 결과를 보여주었다. 본 형제연구는 자녀의 영재성을 극대화시키기 위한 부모의 긍정적인 양육태도에 대한 하나의 시사점을 제공하는 데 그 의의를 둘 수 있다.

Visual Representation Competence Taxonomy (VRC-T) was developed in previous study(Yoon, 2018) to provide a framework conducive to assess visual representation competence and to devise appropriate educational activities for it. This study is an extension of the previous study. It aimed to explore the usefulness of VRC-T and revise it by analyzing the patterns of visual representation use in science lessons. The researcher collected lesson plans on shadow principle from 11 pre-service and 13 in-service elementary teachers and conducted individual interviews regarding what visual representations they considered and how they tried to use them in science lessons. VRC-T was used as an analytical framework to examine the types and cognitive processes of visual representations. As a result, new categories were added and the revised VRC-T was completed (VRC-TR). It was also found that both pre- and in-service teachers mainly focused on 'interpreting' the 'descriptive representation' while designing their lesson plans. Additionally, in-service teachers showed more limited use of visual representations compared to pre-service teachers. In-service teachers largely relied on the national science textbooks, while pre-service teachers reflected their own learning experiences in their teacher-training program. These results showed that teachers' use of visual representations heavily relied on their prior learning and teaching experiences. The VRC-TR presented in this study and examples of class activities in each category can be helpful for teachers and researchers who want to use visual representations more effectively.

The purpose of this paper is to know the effects on number and operation abilities of the 1st grade children of elementary school by applying teaching and learning activity throught communication. For this purpose, we have studied according to the following procedure. 1. We divised teaching and learning model through communication and applied in the actual teaching and learning activity. 2. We investigated the effects of number and operations abilities of the 1st grade children by applying teaching and learning activity through communication. To accomplish this purpose, we applied learning activity through communication to the 1st grade of 40 elementary school children for about six months(September 1, 1999 ～ February 20, 2000). In process of applying this model, we collected all sorts of cases in the children's learning activity and investigated children's response on learning activity through communication, interview with children and researcher's observation. We applied the model through communication in class and compared with the traditional learning. 1. In learning through communication, children could solve the problem in themselves with a sense of responsibility. 2. It was impossible to find out the degree of children's comprehension in the explanatory learning. But in the learning through communication, it was a great help to individualize and plan the learning because children express their ideas clearly. It has conclusion as follows. The learning activity through communication has effected on forming number and operations abilities of the 1st grade of elementary school children importantly. 1. Children have improved in the abilities through communication to express their own ideas. 2. Children have studied with a sense of responsibility not in the teacher-oriented learning but in the self-directed learning 3. Children could find out the mathematical concepts in themselves - correcting false concepts, reguiding concepts by errors, finding invisible errors, solving problems variously and knowing the easy method. 4. The activity through communication in mathematics was a base of children's individual learning and important data of next learning plan. 5. The mathematical concepts formed through communication had a high transfer of learning. 6. Children have taken pleasure of discovery and had affirmative attitude about mathematics learning. We can make sure that number and operations abilities of the 1st grade children are formed by applying teaching and learning activity through communication. However, help and control of teacher have to be with it.

국내 과학 교육 발문 연구에 주로 적용되고 있는 Blosser 발문 분류 체계의 제한점을 고찰하기 위하여 연구자가 교사로 참여한 소그룹 프로그램(중학교 1학년 학생을 대상으로 진행) 중, 총 30여 시간에 걸친 수업 대화 과정을 분석했다. Blosser (1973)의 분류 체계에 따라 분류할 때 열린 발문과 닫힌 발문 등의 구분에 어려움이 있었으며, 같은 내용의 발문이라도 맥락에 따라 다른 종류의 발문으로 분류가 되기도 했고, 적절한 분류 구분을 찾기 어려운 발문도 있었다. 또한 학생들의 사고력 향상이나 수업 참여도에 상위수준 발문(열린 발문)이 하위수준 발문(닫힌 발문)보다 항상 효과적인 것은 아니었다. 발문 전에 교사가 어떤 정보를 제공했는지에 따라 발문의 효과가 달라졌으며, 이전의 발문이 다음에 이어진 발문에도 계속 영향을 주는 사례가 많았다. 그러나 현재 국내 과학 발문 연구에서 주로 행해지고 있는 Blosser (1973)의 분류 체계를 따른 연구에서는, 맥락과 전후 발문이 주는 영향은 무시된 채, 각 개별 발문을 인지 수준에 따라 분류하여 상위 수준 발문의 빈도수로 수업의 질을 평가하고 있다. 현재 국내 과학 교육 발문 연구에서 주로 행해지고 있는 상위 수준 발문의 빈도수로 수업의 질을 평가하는 방식은 지양해야 할 것으로 보인다.
