This study analyzed the current use of science-related test tools in affective area in Korean academic journals for the last 30 years since 1989 and the cases of modification of the original tools related to the tools. This provides practical information on the development and improvement of test tools in the future and offers the basis for developing valid test tools. The study was conducted in two stages. We analyzed the status of 88 domestic science education researches dealing with testing tools related affective characteristics and 57 domestic and foreign resource tools referenced by them. After that, we compared the characteristics of the five cases in which the original tool was revised and the concrete item correction examples. The results were analyzed as follows: topics that have emerged continuously or that have recently begun to appear in domestic research, the research situations according to their purpose and measurement methods used by the tool, and use state of original tools. The background and key points of revision were analyzed for the five tools, TOSRA, SAI, PISA items, STEBI-A/B, SMQ, whose revision process were disclosed. In addition, the changes of the items were analyzed by comparing the four test items with the questions before and after the revision. As a result of item analysis, item improvement was proceeding in the direction of enhancing readability, clarifying meaning, and changing items according to change of sub constructs. The implications of this study are as follows: notes on interpreting the results obtained from the tool with multiple mixed constructs, the possibility of the testing tool that broadens the horizon of the research, error recognition in the subjective self-report, and notes when applying test tools from other disciplines to science.

In this study, I investigated prospective mathematics teachers' perceptions of activities using Wax-paper, a hands-on material (manipulatives), and GeoGebra, a technological tool, in teaching quadratic curves. Twenty prospective mathematics teachers in the Mathematics Education Department of a local university participated in a survey on their perception of the use of hands-on materials and technological tools in teaching quadratic curves. According to the results of this study, prospective mathematics teachers generally preferred the use of technological tools for learning and teaching quadratic curves. Additionally, mathematics teachers thought that the tool helped students develop intuitive thinking through visualizing quadratic curves, enabling the exploration of various mathematical properties, assisting the comprehension of various concepts, and increasing students' interest levels. However, they were concerned about the immature use of technological tools by students or teachers, and recognized that the advantages and disadvantages of using hands-on material and technological tools were complementary. Based on these findings, it is suggested that hands-on material and technological tools should be used complementally in mathematics classes, and the development and dissemination of class materials that are not affected by students' or teachers' ability to use technological tools is important.

The purpose of this study was to investigate the role of calculators as a cognitive tool rather than calculating tool in learning elementary school mathematics. The calculator activities on multiplying two numbers ending with 0s or two decimal fractions and mixed four operations were developed, and exploratory lessons with the activities were implemented to three 3rd graders and two 5th graders. The results were shown that calculators provided an alternative effective learning environment: students were able to use heuristic thinking, reason inductively and successfully investigate principles of mathematics through the pattern recognition. And finally, we discussed the heuristic method through utilizing calculators.

In a rapidly changing society with the Fourth Industrial Revolution, future students should have the skills to utilize and organize high-quality knowledge, not the amount of knowledge. With the launch of the revised curriculum in 2015, the curriculum has been reorganized based on competency and the software education has been seeking capabilities such as 'Cultural computing knowledge', 'Computational thinking', and 'Collaborative problem solving skills'. Therefore, practical collaboration tools and education programs that can be used in the field of education are developed based on Pair Programming, which is a specific collaborative learning strategy to develop cooperative problem solving skill. The educational program using this collaboration tool was developed with a focus on developing computational thinking and collaborative problem solving skills through Pair Programming rather than focusing on learning grammar of programming language and programming techniques. In a educational program, students will be able to use collaborative tools for pair programming and foster collaborative problem-solving skills.

This study indicates there is a need for delivering key academic vocabulary to students with multi-cultural backgrounds before they enter middle school and thus select academic vocabularies necessary for satisfactory middle school education and self-directed learning methods using a more focused selected academic vocabulary list. To this end, we first examine the vocabularies appearing in the main Korean language, math, social studies and science textbooks used in the first year of middle school and compile the most practical academic vocabulary list. Then we offer a selection method for the main academic vocabulary from these compiled vocabularies. We also propose a self-directed vocabulary learning model for using these selected academic vocabularies and an academic vocabulary learning application as a prototype. As a result, students with multi-cultural backgrounds will be able to adapt to middle school education more quickly when they learn the necessary academic vocabularies on their own using the academic vocabulary learning application.

본 논문에서는 블록 프로그래밍 언어를 선행조직자로 하여 텍스트 프로그래밍 언어를 학습하는 도구 활용 전략을 연구하였다. 텍스트 프로그래밍 언어는 파이썬이며, 블록 프로그래밍 언어는 엔트리, 활용하는 도구는 주피터 노트북으로 선정하였다. 주피터 노트북을 활용한 블록 프로그래밍 언어 선행조직자 학습 전략은 code cell에 IPython.display.IFrame 클래스를 활용하여 결과 창에 엔트리 작업환경을 불러와 선행조직자로 제시하여 엔트리를 학습 후 code cell에서 파이썬으로 학습한다. 주피터 노트북을 통해 블록 프로그래밍 언어를 선행조직자로 제시 후 텍스트 프로그래밍 언어를 제시함으로써 텍스트 프로그래밍 언어를 학습할 때 인지적 부담을 줄어들고 긍정적 전이가 일어나 효과적인 학습이 될 것으로 기대된다.

Ministry of Education ＆amp; Human Resources Development has drawn up and carried out various plans to improve the education of the information communication technology application of teachers, who are the most central forces leading the education of the information communication technology. But this current efforts of teachers have put emphasis on the skill-trained abilities. In this study, I compare the internal with the external evaluation tools about the current abilities of the information communication technology application of teachers and have developed the self-evaluation tools for this based on a good point of these tools. Through these evaluation tools, teachers will be able to integrate and evaluate the abilities of the real teaching-learning instruction and the abilities of the information communication technology application on the whole.

This study aims to specify a constructivism-based instructional method using a modular data analysis tool. The value and meaning of a modular data analysis tool have been examined to be applied in the national curriculum for artificial intelligence education and the process of cultivating problem-solving ability based on computational thinking. The modular data analysis tool visually expresses the cognitive thinking process that forms the schema in equilibrating through assimilation and adjustment. Artificial intelligence education has features that embody abstract knowledge and structure the data analysis module through the represented schema as a BlackBox implemented as an algorithm. Therefore, the value of the modular data analysis tool could be examined because it has the advantage of connecting the conceptual and implicit schema.
