프로그래밍 언어 수업은 학습자들 간의 학습 수준의 차이가 크게 나타나고 수업 내용의 연관성이 높은 특성을 가지고 있다. 이로 인해 다른 어떠한 수업보다 학습자들의 학습동기를 향상시켜 지속적으로 학습에 적극적으로 참여할 수 있는 외재적 동기 부여를 통한 학습효과 증진 방법이 필요하다. 본 연구에서는 프로그래밍 교육에서 성찰일지를 활용한 학습동기 증진 교수 학습 모델을 제시하고, 실제 수업에 적용 후 학습동기에 대한 사전 사후 설문을 실시하여 제시한 교수 학습 모델이 학습동기 증진에 효과 있었음을 조사 분석하였다.

Documentation is a typical method that helps students to understand a program for implementation and execute error correction and maintenance cost-effectively. Guidelines for components that organize documentation should be provided to enable to express computational thinking and such components also should be linked to coding process. In this paper, we focused on the documentation format to guide elementary school students, who were beginners in computational thinking, to express computational thinking. The improvement in the expression of computational thinking was analyzed based on the documentation format applied to the class, and practical tips on the importance of components organizing the documentation format were proposed.

This paper presents a method of grinding and polishing automation of precision die after CNC machining. The method employs a robot system equipped with a pneumatic spindle and a special abrasive film pad. The robote program is automatically generated off-line from a PC and downloaded to robot controller. Position and orientation data for the program is supplied from cutter contact (CC) data of NC machining process. This eliminates separate robot teaching process. This paper aims at practical automation of die finishing process which is very time consuming and suffering from shortage of workpeople. Time loss for changeover from one product to next is eliminated by off-line programming exploiting appropriate NC machining data. Dextrous 6-axis robot with rigid wrist and simple tooling enables the process applicable to larger, rather complex 3 dimensional free surfaces

In order to achieve high accuracy of teaching and increase productivity using industrial robots in polishing process of dies, an off-line task programming system was developed on IBM-PC/386 under WINDOWS 3.0 operating system. The internal structure and the machematical basis of CAMPoli are described. Surface modeling technique of polishing dies with sculptured surfaces is introduced by poing data interpolation methodology through the use of CL-data transmitted from conventional CAM system. Tool selection, polishing speed, polishing pressure and kinds of tool motions can be determined and selected by user specified polishing variables. Task creation and verification of polishing path via computer graphics simulation of polishing tool can be done by the menu- driven function of CAMPoli system. Post-processing module is attached to generate robot language. Some simulation results are provided as verification means of the system.

This paper addresses an intelligent robot control system using an off-line programming to teach a precise assembly task of electronic components in a flexible way. The investigated task consists of three job: heat caulking test, soldering on a circuit board, and checking of soldering defects on the back cover of a camera. This study investigates the remodelling of the most complicated cell in terms of the accuracy and fault rate among the twelve cells in a camera back-cover assembly line. We have attempted to enhance back-cover assembly line. We have attempted to enhance soldering quality, to add task flexibility, to reduce failure rate, and to increase product reliability. This study modifies the cell structure, and improves the soldering condition. The developed all system implements the real-time control of assembly with vision data, and realized an easier task teaching on off-line programming.

In this paper, we propose to investigate the existing EPL education related studies and to collect the total effect size for the improvement of high-level thinking through meta-analysis and to confirm the effect size according to various variables. So, we have objectively identified and generalized the practical effects of EPL education on the various elements of high-level thinking and high-level thinking. The results of the meta-analysis showed that 1) EPL is a teaching-learning tool that greatly improves students' high-level thinking. 2) Education based EPL has greatly contributed to the enhancement of creative thinking and logical thinking among high-level thinking. 3) Kodu, App Inventor, Scratch, and Dolittle was confirmed that the effect on the improvement of high-level thinking was great.

In this paper, we propose the computational thinking education framework which provides three steps of computational thinking process and three kind of activities about computational thinking learning in class. The key idea of this framework is to provide the guidelines of designing activity steps of teaching and learning computational thinking in class using three axles of framework such as problem area, process of learning, and steps of computational thinking process. After designing a framework, we show that sample course of programming education program containing contents of Informatics subject in middle school by implementing our framework. Proposed framework and programming education program in middle school will be the good case study and guide to implement computational thinking concerned education programs in elementary, secondary, and universities.

2015 개정 교육과정에 따라 초등학교 및 중학교에 프로그래밍 교육이 필수로 도입된다. 그러나 과거 5차 교육과정에도 프로그래밍 교육이 도입되었지만 지속되지 못했다. 프로그래밍 교육이 지속 가능하기 위해서는 다양한 요인을 고려하여 프로그래밍 학습 환경을 설계해야한다. 특히 학생들의 흥미, 관심, 그리고 긍정적인 태도등의 정의적 요인을 고려하여 교수학습 방법을 적용하는 것이 중요하다. 본 연구는 학생들에게 프로그래밍 교육을 어떻게 가르치는 것이 정의적 영역에 긍정적인 영향을 주는지 다양한 프로그래밍 교육 연구를 메타 분석하여 시사점을 제시하고자 하였다. 이를 위해 학습자들이 프로그래밍 교육을 통해 얻은 정의적 영역의 교육 효과를 교수학습 방법별로 메타 분석하였다. 프로그래밍 교육과 관련하여 수집한 연구 논문은 메타 분석 방법에 따라 단계별로 연구 자료를 추출하고 선정하는 절차를 통해 분석하였다.

As a consequence of sudden outbreak of COVID-19 pandemic worldwide, educational institutes around the globe are forced to switch from traditional learning systems to e-learning systems. This has led to a variety of technology-driven pedagogies in e-teaching as well as e-learning. In order to take the best advantage, an appropriate understanding of the cognitive capability is of prime importance. This paper presents an intelligent cognitive maturity recognition system for confidence-based e-learning. We gather the data from actual test environment by involving a number of students and academicians to act as experts. Then a Genetic Programming based simulation and modeling is applied to generate a generalized classifier in the form of a mathematical expression. The simulation is derived towards an optimal space by carefully designed fitness function and assigning a range to each of the class labels. Experimental results validate that the proposed method yields comparative and superior results which makes it feasible to be used in real world scenarios.
