Korean Secondary Students' Perceptions toward the Cyber Home Learning System-based ELT Contents
이종직,박명수 한국영어교육학회 2012 ENGLISH TEACHING(영어교육) Vol.67 No.1
This paper aims to examine the online learning service called the Cyber Home Learning System (CHLS), which was introduced in 2004 and has been in operation nationwide since 2005. It appears questionable as yet whether the CHLS has obtained a promising outcome. This study, therefore, aims to investigate how many secondary students are currently utilizing the English contents in the CHLS and how they perceive this service. The results of this study indicated that English contents of the CHLS were utilized by only a small number of students, and the contents were rarely perceived as useful. In particular, students perceived that there was little interaction with teachers in cyber space as well as in a classroom setting. Furthermore, five items were identified as the major reasons that hinder students from using the CHLS: lack of promotion; difficulty of self-directed learning; lack of time; low quality; and inconvenience. The results of this study suggest that teachers are influential in affecting students’ perception toward the CHLS, and that it is of paramount importance to renew the CHLS based on the results of a needs analysis.
Guided Teaching of Reflective Writing Skills in a Korean High School English Class
이종직,정영철 현대영미어문학회 2023 현대영미어문학 Vol.41 No.3
This study aimed to examine the levels of reflection that Korean high school students demonstrated in their English essay writings and investigate the degrees of change in the levels of reflection resulting from teacher intervention. Students’ perceptions towards teacher intervention were also scrutinized. For these research purposes, two English essays from each member of a class of twenty students were analyzed according to van Manen’s (1977) classification. Students’ reflection notes and questionnaire survey responses were also examined in a qualitative way. The results of this study revealed that the proportion of students’ writing categorized as critical reflection was very low, although the levels of their reflection improved through guided teaching with teacher intervention. It was also found that the degrees of acceptance of teacher feedback varied depending on the students’ tendencies and levels of reflection. This study shows that teaching critical writing skills to high school students in Korea is challenging, but their reflective thinking skills can be gradually enhanced through guided teaching.
DeviceNet을 이용한 다이나모미터의 제어 시스템에 관한 연구
이종직(Jong-jik Lee),이용범(Yong-bum Lee),이기천(Gi-Chun Lee) 대한기계학회 2013 대한기계학회 춘추학술대회 Vol.2013 No.12
In this paper, a real-time control algorithm was developed using DeviceNet communication to control rotating power sources such as engine or dynamometer operated for the performance and durability tests of rotating machines. The test equipment which was joined with the algorithm comprised a input dynamometer, test objects (gearbox and transmission), and output dynamometer for torque control. Consequently the test results in this study showed that using DeviceNet communication led to remarkably efficient control.
