The purpose of science education is scientific literacy, which is extended in its meaning in the $21^{st}$ century. Students must be equipped with the skills necessary to solve problems from the community beyond obtaining the knowledge from curiosity, which is called 'computational thinking'. In this paper, the authors tried to define computational thinking in science education from the view of scientific literacy in the $21^{st}$ century; (1) computational thinking is an explicit skill shown in the two steps of abstracting the problems and automating solutions, (2) computational thinking consists of concrete components and practices which are observable and measurable, (3) computational thinking is a catalyst for STEAM (Science, Technology, Engineering, Arts, and Mathematics) education, and (4) computational thinking is a cognitive process to be learned. More implication about the necessity of including computational thinking and its emphasis in implementing in science teaching and learning for the envisioned scientific literacy is added.

The high school students' problem solving patterns and their features in scientific inquiry, especially on controlling variables and stating hypothesis have been investigated. The 8 problems on controlling variables and stating hypothesis were selected out of the scientific inquiry area in the experimental tryout of Aptitude Assessment for College Education, and had been used to find the patterns and their features. The results of findings are as follows: There were seven patterns in the process of solving problems. Five of seven patterns were found in right answers and four patterns in wrong answers. Two patterns were found in both right and wrong answers. Some students could solve the problems even though they did not understand the elements of the scientific inquiry, controlling variables and stating hypothesis. The false application of physics concepts, misunderstanding about the elements of the scientific inquiry and using unrelated experience and conjectures were the features of students' wrong answers. On the other hand, the right application of physics concepts, understanding and applying the elements right, infering answers from the tables and figures on statements of suggested problems were the features of right answers. The further studies on this kind may helpful to find the higher mental abilities related to scientific inquiry and to develop tools for testing students' scientific inquiry thinking skills.

This study investigated the literature about science process skills' evaluation to analyse transition of evaluation objectives before and after a Scholastic Ability Test for College Entrance. In the literature survey the researcher established a 3 dimensional science assessment framework with X axis as science concept, Y axis as science process skills and Z axis as problem context. In order to analysis and compare each items the researcher selected 210 items from the 1st to the 7th trials and 138 items from the 1st to 4th Scholastic Ability Test for College Entrance and sampled 2873 science achievement test items from 10 high schools. In accordance with this taxonomy the researcher analysed and compared science process skills item forms. The following results were drawn : The items were evenly distributed in all the four areas(Earth Science, Biology, Physics and Chemistry) of the science concept domain, but they were heavily concentrated on data analysis and drawing a conclusion in science process domain. In the domain of problem context school context was the majority. In spite of distribution like this the ratio on science process skills measurement items and science achievement test items was increased after the Scholastic Ability Test for College Entrance was given. Also the ratio on item expression type was increased. Item form was almost 5 options selection type in the national level test. Although there were 4 options selection type, 5 options selection type, short answer type, essay type in school level test, rising from 33.1% to 65.5% on 5 options selection type is exhibited. This study showed that the school level item form was better various than the nation level. This point like this is the evidence for the improvement toward the science process skills test and influenced by Scholastic Ability Test for College Entrance. The ratio on the item which joined with the 3 axes had a mean of 99.3% in nation level test and mean 44.9% in school achievement test level. But the ratio in the school achievement test level increased after the Scholastic Ability Test for College Entrance was given. In view of this study we must furthermore study the item types which can evaluate valjdately science process skill's five stage each and evaluation method by the high school students' problem solving patterns and features in scientific inquiry on all science process skills elements.

In this study, a problem-centered learning based STEAM field experience learning program was developed and the effects of applying it were investigated. The program was composed of 8 sessions by using problem-centered learning education method and integrating STEAM elements between disciplines. The contents of program are as follow. In the step of sharing problems and making a problem-solving plan, they understood the various examples and meanings of endangered species, explored the project activities, and made an inquiry plan. In the search and re-exploration phase, a smart device was used to investigate the appearance, habitat environment and cause of extinction for Clithon retropictus, and a site inquiry plan was established for each group. Then, they moved to the field to explore brackish-headed gallops and discuss ways to protect endangered species. In the step of creating a solution, a web-based report was produced as the final product using smart devices based on the results of the inquiry. In the presentation and evaluation stage, the produced web-based report was used to present each group, conduct mutual evaluation, and organize project activities. The developed program was applied to 6th grade 29 students enrolled in the J University Gifted Education Center. In order to find out the effectiveness of the program, tests of science process skill, creative problem-solving ability, and scientific attitude were conducted before and after of program learning, and the results were statistically analyzed by t-test. In addition, a STEAM program satisfaction test was conducted after project in order to find out the satisfaction of the class. As a result of application of the program, the results were significantly improved in openness, criticism, and creativity among the sub-factors of creative problem-solving ability and scientific attitude. Satisfaction with the STEAM program was also high, but no significant result was found in science process skill. Therefore, the program of this study could be influenced on improvement of creative problem-solving ability and scientific attitude of gifted students in elementary science.

본 연구의 목적은 과학 탐구에 대한 기능 중심의 접근에 대해 비판적으로 살펴보고 최근 과학 교육 개혁에서 강조되고 있는 과학적 실천의 의미를 시험적으로 탐색하는 것이었다. 이를 위하여 관련 문헌들을 수집하여 고찰하였으며, 그 결과를 세부 주제에 따라 정리하였다. Science-A Process Approach (SAPA)로 대표되는 기능 중심의 접근에서는 과학 탐구 기능들을 위계적으로 연계하여 제시하고, 이들은 전이성 또는 일반화 가능성이 높다고 주장하였으며, 발견을 통한 과학 학습을 강조하였다. 하지만 이러한 입장은 기능의 사용에 이론이 적재되어 있다는 현대 과학 철학의 관점과 상충되었으며, 탐구에서 사용되는 기능들이 내용-특이적 또는 맥락-의존적이라는 사실과 추상적인 과학 이론이나 원리는 귀납적으로 발견될 수 없다는 점에서 비판을 받아 왔다. 이와는 달리 과학적 실천을 강조하는 최근의 입장에서는 과학적 실천을 총체적인 행위로 이해하고, 그것이 전개되는 양상은 내용이나 맥락에 따라 다르다는 점을 강조하며, 과학 수업에서도 학생의 아이디어를 중요하게 고려하고자 한다. 이러한 연구 결과는 과학 탐구에 관한 일관된 관점을 정립하는 데 시사점을 제공함으로써 새로운 과학 교육과정 개발에 기여할 수 있을 것이다.

The purpose of this paper is to survey the definition and scope of English Education as an academic discipline or science, relating to English linguistics, linguistics and applied linguistics. English Education has come to be regarded as fulfilling its true function when it is based on the solid scientific principles and methods of such related sciences as linguistics, English linguistics, psycholinguistics, sociolinguistics, sociology, psychology and pedagogy. English Education is, therefore, an independent and specialized applied science, interrelated with the sciences mentioned above. Thus, English Education is defined as an academic discipline which is concerned with the concrete teaching and learning of English, and which is based on the scientific methods, applications and evaluations of English. As a science, English Education has three elements: content, process and methods. Content, which concerns input, consists of the fundamental interrelated sciences and English language skills. Process refers to research methodology and analysis. Methods are the application of the theories and the processes.

본 연구에서는 과학 교사를 양성하는 사범대학 과학교육과 학생들의 일반화학실험 수행평가를 위한 분석적인 채점 준거를 개발하였다. 개발된 채점준거는 크게 두 가지로 나눌 수 있다. 첫 번째는 학생들이 실험을 수행하면서 나타나는 탐구 능력을 평가하기 위한 실험 보고서를 평가하는 분석적 채점 준거이다. 이 분석적 채점 준거는 일곱 가지 탐구 기능 요소로 나누어져 있으며, 한 학기용 실험 주제 9개에 대해서 모두 개발하였다. 두 번째는 학생들이 실험하는 동안에 교수와 조교가 직접적인 관찰에 의해 점검하는 형태로 평가하는 수공적 기능 채점 준거와 실험에 임하는 학생들의 태도를 평가하기 위한 분석적 채점 준거이다. 또한 학생들의 탐구 능력을 평가하는 실험 보고서에 대한 분석적 채점 준거의 기초가 되는 일곱가지 탐구 기능 요소에 대한 일반적 채점 준거도 개발하였다. 모든 채점 준거에 대한 타당도는 과학교육 전문가 6인에 의하여 검증 받았으며, 채점 준거로 실험 보고서를 평가한 결과로부터 채점자간 신뢰도를 검증하였다. 본 연구에서 개발한 평가 도구를 사용하여 얻어진 학생들의 일반화학실험 수업 성취도와 일반화학 이론 수업 성취도는 상관이 있는 것(r=.663.p<.01)으로 나타났으며. 44%($r^2$=.440)의 공통 분산 영역을 보여주었다. 따라서 본 연구에서 개발한 실험 평가 도구는 이론 수업 평가 도구에서 측정하지 못하는 다른 영역(56%)도 평가하고 있음을 알 수 있었다. 이러한 결과로부터 간접적으로나마 본 연구에서 개발한 실험 평가 도구가 전통적인 지식 이해만이 아닌, 실험을 수행하면서 나타난 탐구 기능, 수공적 기능, 실험 태도를 평가하는 도구라고 할 수 있다.

The purpose of this study is to introduce the science-play in the regular class, stimulate the student's curiosity, motivate them and take active part in their science class. To make an effective science class, we developed the science-play activity instead of experiments in the text, and applied it to the class. The experimental group has statistically meaningful results in the science process skills, expecially in subordinate elements such as observation, deduction, expectation, data analysis and assumption establishments(p<.01). However, the comparative group has no meaningful results in the science process skills. Though the average value of the science related attitude in the experimental group had only a little increase and had no statistically meaningful results, that in the comparative group has decreased during the same period. As for the experimental group, the science-play activities were repeated and their science related attitude has increased a little. Even though there were no meaningful statistic results(p>.05), the science-play activity was effective in the science related attitude. As a result of this research, it could be said that the science-play activity can improve the student's science process skills and the science related attitude, and the science-play program should be further developed and applied to make easy and effective science classes.
