The purpose of this study was to investigate the characteristics of lesson planning of pre-service elementary teachers to develop scientific communication skills for elementary school students. For this purpose, lesson plans and lesson planning journals written by the 53 pre-service teachers were collected and analyzed. The results of the research were as follows. The pre-service elementary teachers used an implicit and contextual approach to develop scientific communication skills. Teaching and learning activities for enhancing scientific communication were mainly conducted in words or in writing. There were many activities expressing elementary school students' thoughts and presenting the results of experiments in the lesson plan. There were many cases in which the pre-service teachers' lesson plans did not include the evaluation of scientific communication skills. In their lesson plans, there are a lot of mutual activities between teachers and students, team and whole students, and inter-students within teams together, and students' individual activities from requests of teachers. We found that the pre-service teachers had various difficulties when they planned the science lesson to develop scientific communication skills. The pre-service teachers were less likely to refer to specialized materials related to science education when planning their classes.

자신이 쓴 문장과 유사한 문장을 살펴보는 것은 초등 글쓰기 교육을 위한 효과적인 방법 중 하나이지만, 매번 글을 쓸 때마다 교사의 지도가 필요하기 때문에 현실적으로 활용하기 쉽지 않다. 본 논문에서는 이 한계를 극복하기 위해 컴퓨터가 자동으로 자신이 쓴 문장과 유사한 문장을 실시간으로 선별해 주는 방법을 제안한다. 이 방법은 단어의 구성 성분을 쪼개는 단계, 쪼갠 단어를 입력으로 활용하여 인코더-디코더 모델을 학습하는 단계, 모델을 통해 얻어낸 추상화된 문장을 활용해 검색하는 단계로 구성된다. 실험 결과, 작은 규모의 데이터에 대해 75%의 정확도를 보임으로써 실용화 가능성이 높은 것으로 나타났다. 이 방법을 통해 학생들은 자신의 어색한 문장을 교정하거나 새로운 표현을 익히고 싶은 경우 다른 사람이 작성한 좋은 예문을 쉽게 참조할 수 있어 자신의 글쓰기 능력을 향상시키는 데에 큰 도움이 될 것으로 기대된다.

This paper examines the relationship between children's English proficiency in grade three and English learning environment and experiences before entering elementary school. In English learning environment and experiences, three influences consisting of children, home environment, and environmental influences of English learning are used to find out which influences contributed to children's English proficiency in grade three of elementary school. The result of this study shows that children with high interest in English have higher proficiency in all language skills reading, writing, listening, and speaking than that of children with low interests. For parents' influences, parents' high interests toward their children's English leaning and high monthly income result in children's high English proficiency. For English environmental influences, children who start at the early age and continue studying English have higher English proficiency.

The purpose of this study was to analyze the understanding of the sighting and hearing elementary school students have through drawing. For this purpose, we conducted a questionnaire survey of 602 elementary school students. The questionnaire was composed with open-ended question developed by West et al.(2008). This questionnaire was presented only appearance of face. And let them express the sensory pathway by drawing and writing. The students' responses for questionnaire were classified by 5 levels. Inner-researcher consistency was 0.89, inter-researcher consistency was 0.83. The data analyzed were ${\chi}^2$ by using SPSS. The result of this study were as following: First, elementary school students have misconception of sighting and hearing. There were no difference among the grade. In spite of becoming upper grade, students have still misconception. Second, scientific concept that male students have were significantly more than female. Third, the concepts of the anatomically organs are more exposed in real-life situations, students known better. Within these results, it would be used for developing teaching-learning strategies which can use misconceptions students have.

21세기 지식 정보 사회에 인공지능 교육이 매우 중요하다. 4차 산업혁명 시대에 컴퓨터 교육에서 인공지능을 이해하고 컴퓨터 프로그래밍 교육을 해 보는 것이 매우 중요하지만 인공지능에 대해서 이해하고, 컴퓨터 프로그래밍 교육을 하는 교수 학습 모델이 없다. 본 연구에서는 제안하는 모델은 문제 이해 단계, 데이터 정리하기 단계, 인공지능 모델 정하기 단계, 프로그래밍하기 단계, 보고서 작성하기 단계로 구성된다. 프로그래밍하기 단계에서는 학생들의 수준에 적합하게 복사하기, 변형하기, 창조하기, 도전하기로 나눌 수 있다. 본 연구에서는 초등학교 교사들의 델파이 평가로 모델의 타당도를 입증하였고, 그에 따라 초등학생들이 쉽게 이해할 수 있는 사례를 만들었다. 본 연구의 결과는 초등학생들에서 인공지능 프로그램을 실습해 볼 수 있는 좋은 기회를 제공한다.

In this study, we applied the elementary performance assessment instrument on 575 theme in science instruction which it had been developed on the previous study. Sixty-seven elementary students participated in this study and were assigned into two groups: One was assigned to an experimental group since they were taught with the instrument (N=32) and the other was assigned to the comparison group since they followed teachers guide of 7th Korean National Curriculum (N=35). Prior to and after teaching, tests on the science attitude, science process skill, and science knowledge domains were administrated. The results were analyzed quantitatively. Further, we also investigated students recognition about the instrument and the science class qualitatively according to the instrument. The results showed that there were statistically significant improvements on science process skills and aspects of the understanding of science knowledge. Many students were aware of them positively as well. However, a few problems, including too many amounts of writing and difficulties in communication with one another, were appeared.

본 연구는 초등학생을 대상으로 PBL 기반의 프로그래밍 학습 과정에서 구조화된 성찰일지 작성 활동이 논리적 사고력에 미치는 영향을 분석하기 위해 성찰일지 작성 전후 논리적 사고력의 차이를 비교하여 효과를 분석하였다. 연구를 위해 초등학교 5학년 59명 학생들을 대상으로 실험집단과 통제집단을 구성하고 실험집단에는 PBL 기반의 프로그래밍 학습 단계별로 내용, 과정, 비판적 성찰일지 작성을 적용하였고 통제집단에는 PBL 기반의 프로그래밍 학습 단계별로 비구조화된 성찰일지 작성을 적용하였다. 연구 결과 실험집단의 구조화된 성찰일지 작성 전후의 논리적 사고력 차이를 공분산분석(ANCOVA)을 통해 분석한 결과 유의수준 .05에서 학습효과가 있음을 확인했고 통제집단과 논리적 사고력의 차이를 비교한 결과에서도 학습효과가 있음을 확인했다. 이를 통해 초등학교 5학년 학생을 대상으로 하는 PBL 기반의 프로그래밍 학습에서 구조화된 성찰일지 작성 학습자의 논리적 사고력 향상에 효과가 있음을 알 수 있었다.

This study plans to develop strategies using children's verse in science education and investigate the effects of instruction using children's verses on the attitude toward science. The study tried to determine strategies using children's science verse in order to find out their value. For the purpose of this, two classes of the 6th grade were selected in an elementary school for tests. The results from this research showed that strategies using children's verse in science education were developed and applied in teaching/learning purposes as well as in the area of literature. A strategy for remembering was applied widely. A strategy for understanding scientific principles and for quest methods, writing children's science verses directly helped in scientific conceptual formation. Instruction using children's science verses had a positive effect on the attitudes toward science. Students maintained positive attitudes throughout instruction that used children's science verses. In conclusion, instruction using children's science verses can be applied to science education, and the attitudes toward science and learning achievements can be improved.
