본 연구의 목적은 예비 교사의 소프트웨어 교육 수업 전문성 함양을 위하여 백워드 설계 기반으로 교육프로그램을 개발하는 데 있다. 백워드 설계는 학생들의 심층적인 이해를 고려한 수업 설계 기법이다. 백워드 설계 대한 이론적 배경을 바탕으로 차시 당 4시간 수업으로 총 8차시(32시간 분량)의 소프트웨어 교육 프로그램을 개발하였다. 이는 예비교사의 소프트웨어 교육에 대한 심층적인 이해를 돕고, 직접 백워드 설계를 기반으로 하는 수업 계획을 실습함으로써 교육과정에 대한 깊은 이해도 도울 수 있다는 점에 의의를 갖는다. 하지만 본 연구에서 개발된 교육 프로그램이 어떤 효과성을 지니는지에 대한 검증이 이루어지지 않았다는 제한점이 있다. 따라서 추후 연구에서는 효과성을 확인하기 위한 실험 및 통계적 검증이 요구된다.

컴퓨터 관련 인프라가 양적으로 팽창하는 지식 정보화 사회에서 컴퓨터 교육은 기초 기본 교육과 더불어 필수적으로 이루어져야 한다. 본 논문에서는 학생들이 쉽게 그리고 많이 접하는 웹에 관한 내용을 지도함에 있어 단순히 인터넷 검색이 아니라 어떻게 웹 페이지가 만들어지는지에 초점을 두었다. 이를 위해 PBL기반 HTML 텍스트 에디터를 구현하고 이를 수업에 직접 적용하여 배운 내용에 관한 형성 평가와 HTML 수업에 대한 흥미나 관심도 등을 설문지를 통해 알아보았다. 실험 결과 실험 집단과 통제 집단 사이에서 에디터로 인한 형성평가 성취도에는 차이가 없었다. 설문지를 통해 조사한 정의적인 영역은 7문항 중 수업의 난이도를 질문한 문항과 앞으로 홈페이지를 만들 수 있는가를 질문한 문항에서만 유의미한 차이를 보였다. PBL 기반의 HTML 텍스트 에디터는 인지적 영역의 성취도에서는 큰 차이를 보이지 않지만 직접 HTML 태그를 치지 않는 에디터를 이용해도 HTML과 관련된 지식을 습득할 수 있음을 보여준다.

This study analyzes the effects of programming-based TPACK education programs, designed by Kim and Lee (2019), on the teaching expertise of pre-service teachers. The research subjects were 40 pre-service teachers, divided into an experimental group and a control group. The experimental group underwent the programming-based TPACK education program, and the control group used an ICT-based TPACK education program. A test tool was used to measure not only teaching expertise but also teaching efficacy and self-efficacy beliefs about technology integration. As a result of the study, teaching expertise, teaching efficacy, and self-efficacy beliefs about technology integration improved significantly in the experimental group. The pretest showed no significant difference between the experimental group and the control group, but in the post-test, the experimental group showed significantly higher teaching expertise than the control group. These results showed that the programming-based TPACK education program is effective for developing teaching expertise in pre-service teachers.

This paper suggests efficient learning improvement method of computer use instruction based on flipped learning. Traditional computer use classes were difficult to practice and collaborative with sufficient lectures. However, we used KOCW (Korea Open Courseware) as a footsteps in the class using the flipped learning method and learned in advance before entering the classroom. In the classroom, we conducted collaborative hands on class based on mutual discussion. After the instruction, we measured learning motivation and satisfaction by gender, grade, and major using the motivation test tool. The results showed that degree of attention awareness, perception of class relevance and perception of learning satisfaction were analyzed as 'very satisfied' and 'satisfied' more than 90%.

This paper aims at implementing experimental devices with which middle school students can explore scientific ideas using GoGo Board and NetLogo that connect real and simulated worlds. Related research literature was reviewed to design a simulation-based learning model using computer simulation and robot-related activities. In order to construct devices for exploratory experiments, GoGo Board was adopted for developing the interface of Micro-Based Laboratory(MBL) devices with several sensors while NetLogo was used for connecting MBL devices (real world) and simulated experiments (virtual world). The simulation contents were developed in the area of heat equilibrium for changing temperature and the conduct-current relationship appeared in the textbook of middle school science class. With the developed device and contents students can visualize the change of temperature cold and hot waters in terms of heat equilibrium. They also can measure the change of conductor representing the relationship between conductor and current. The formative evaluation of the contents carried out with several middle school students indicated the future direction for upgrading simulation contents and interface. The results might be beneficial for science educators who want to apply simulation contents with the use of computers.

In the web- based educational system, how to improve interaction among learners are very important by the Internet. Therefore interpersonal interaction is essential for a good educational environment. In this paper, a web-based PBL(Problem-Based Learning) system is designed and implemented to improve learner's interaction. I investigated how the method for improving interaction affect PBL activities and how students perceive the web-based PBL learning experience. The result of experiment showed that the suggested system facilitated learners' self-directed learning process and interaction.

This research examines educational effects on students' scientific process skills after applying a robot utilized MBL learning. Surveys and interviews concerning robot based science lessons were also conducted. The students were divided into experiment group who used the robots and controlled group who used traditional learning method with textbook and experiments. The result showed some significant differences in scientific measurement, prediction and inference(<.05). In contrast, no significant differences were found in observation and classification. The students answered the survey that the robots helped them understand science better and made science lessons more interesting.

This thesis focuses on developing an appropriate model for teaching internet ethics based on problem-based learning, and studying its effect on morality. The PBL model is focused on encouraging participation from students through discussion and essay-writing. To test the validity of the new model, the control group was constructed and was assigned an existing lecture-based model. The research applied the new method at class and compared changes in Internet ethics between two groups. The results showed that the PBL model was more effective in enhancing internet ethics among students than the lecture-based model, and they were statistically valid. Especially, the "responsibility" part within the internet ethics showed the biggest improvement.

In order to measure students' fun and the effectiveness of teaching materials related to computer science theory, this paper conducted an experiment lesson against middle school students using Timbel's 'Unplugged' textbook. A preliminary test was conducted and it revealed that the students' understanding of computer science theory was extremely poor. The learner's fun for the experimental lesson showed the positive reaction in the viewpoint of expectation, engagement, endurability. In post-test after one month, the students were able to recall most of the materials covered during the experiment lesson. In addition, they all showed sign of good understanding. In conclusion, Timbel's textbook proved effective in increasing students' fun and learning ability related to computer science theory. Furthermore, this paper would like to suggest a new type of Informatics science teaching material that might be essential for future computer science education.

테크놀로지가 교육에 활발하게 도입됨에 따라 수업에 교사가 테크놀로지를 활용할 수 있는 역량을 향상시키기 위하여 Technological Pedagogical Content Knowledge(TPACK)이 등장하였다. 테크놀로지의 발달에 따라 TPACK 연구가 활발하게 진행되었다. 이러한 흐름에 발맞추어 김성원과 이영준(2017)은 예비 교사의 수업 전문성 향상을 위한 프로그래밍 기반 TPACK 교육 프로그램을 개발하였다. 또한, 김성원과 이영준(2018)의 연구를 통하여 프로그래밍 기반 TPACK 교육 프로그램을 개선하였다. 본 연구에서는 프로그래밍 기반 TPACK 교육 프로그램의 개선이 예비 교사의 자아 효능감에 미치는 효과를 살펴보았다. 연구를 위하여 대조군에게는 기존의 프로그래밍 기반 TPACK 교육 프로그램을 적용하였다. 실험군에게는 개선된 프로그래밍 기반 TPACK 교육 프로그램을 적용하였다. 그 결과, 사전 검사에서는 두 집단 간의 자아 효능감은 같았다. 사후 검사에서는 실험군이 대조군보다 자신감과 과제 난이도 선호에서 유의미한 차이가 나타났다. 이를 통하여 프로그래밍 기반 TPACK 교육 프로그램의 개선이 예비 교사의 자아 효능감의 세부 영역에 효과적인 것으로 나타났다. 본 연구에서는 자아 효능감의 모든 영역에서 향상이 나타나지 않았다. 향후 연구에서는 자기 조절 효능감까지 향상될 수 있도록 교육 프로그램의 개선이 이루어져야 한다.
