Objectives: The purpose of the study was to investigate the satisfaction with instruction medium according to learner attitude and lecture mode in the dental hygiene students. Methods: A web-based self-reported questionnaire was complected by 155 dental hygiene students in Cheonan from May 26 to June 5, 2015. The questionnaire consisted of general characteristics of the subjects, school adaptation, interest to learn, effort to learn, faculty centered lecture, learner centered lecture, self-directed learning, motivation to learn, characteristics of each subject, and satisfaction with lecture mode. The study was approved by institutional review board (IRB) by Baekseok University. Chi-square test and multivariate logistic regression were used to evaluate the satisfaction to medium of instruction according to explanation factors. Results: The lecture mode, opportunity and motivation to learn, interest to learn and effort to learn were the significant factors to satisfaction with instruction medium. In multivariate logistic regression model, the adjusted odds ratio was 6.28 for the opportunity to learn and 4.87 for the interesting to learn. Conclusions: The satisfaction with instruction medium is the most important factor that decides the lecture mode and learner attitude including opportunity to learn and concern to learn.

The purpose of this study was to synthesize the effects of the information literacy instruction using meta-analysis. Results using random-effect models were as follows. First, the overall average effect size (ES) of information literacy instruction (Hedges'g) was 0.72, which could be interpreted based on Cohen's guidelines as moderate to large. Second, the two types of information literacy instruction, demonstrating more than medium ESs, did not show significant differences in their ESs. Third, the ESs of information literacy instruction differed depending on the measuring variables. Fourth, grade, study design and the form of the measurement tool were moderator variables that explain the differences in ESs. In sum, the effects of information literacy instruction, having more than medium effect size, seem quite stable across instruction types and study designs.

The purpose of the study is to investigate the effectiveness of the cultural instruction based on the critical pedagogy through film. The participants were 21 college students enrolling 'Understanding American/British culture'class and the class was 15 week long. During class, they discussed and selected the cultural topics related to the movies, complete the research papers, and then gave presentations. The students' portfolio, which consists of the goal statements, research papers, and the reflective journals, was analyzed to investigate the effectiveness of the instruction. The results showed that the instruction was effective in five aspects. They are, 1)accumulation of the cultural knowledge, 2)better understanding of the target culture and its people, 3)acquisition of the critical perspectives toward the target and their own cultures, 4)teaching method, and 5)increase of the motivation for studying other cultures. The study suggested that the instruction should be applied to English-medium class with more advanced students.

EMI (English as a Medium of Instruction) classes are now accepted policy at Korean universities, yet students often struggle with required academic English writings. The present study examined an EMI class that used direct instruction and access to online assistive English writing software. From preliminary analysis, 26 students expressed interest in how an EMI academic writing class could facilitate improved English writing skills. Study participants completed a survey on self-efficacy and learning needs and assignments for an EMI academic writing class. To establish inter-rater reliability, three trained raters assessed the written essays of students prior to and after instructional intervention. Fleiss' Kappas statistics showed moderate reliability. Students' opinions on the use of online software were also analysed. Paired t-test was run on the quality of students' pre- and post-instruction assignments, and there was significant difference in the rated scores. Self-efficacy was found to have moderate positive association with improved post-essay writing scores.

This article explores how we pursue and operate the English medium instruction(EMI) in engineering colleges so as to educate global engineers. Engineering students in the 21st century society need to have fundamental work in languages, cultural differences, and strategies for working with diverse colleagues. EMI is not sufficient for preparing our engineering students to cope with the changed environments in our globalized society. Based on the case study, we emphasize that EMI needs to be located in the context of global engineering education which demands our understanding of different cultures and communication practices. We also suggest some programs how we develop our EMI circumstances.

This study investigates English medium instruction (EMI) in an institution of higher education in Seoul, Korea to see whether this course creates cultural correction (reproduction of inequitable relations of power in EMI settings) or cultural continuity (opportunities for transporting students into a third space and enabling them to explore cultural diversity and to create new knowledge for themselves). A single site where EMI is carried out, a class on fairy tales and child education taught by a native English speaking professor, was chosen because it was hypothesized that the professor would display some of her unconscious dominant cultural orientation. The results of the study show that there more cases of cultural correction than there were of cultural continuity. Cases of cultural correction included lack of knowledge about the local context, fixing Korean classroom discourse as if it were American classroom discourse, and reproducing orientalism in the local educational setting. Cases of cultural continuity included using comparison to consider the cultural reality of the milieu, creating new knowledge for the local milieu, and learning as a dynamic ongoing process. Implications of this research are discussed including the important realization that EMI should be managed by subject specialists who are trained in language education and have knowledge of the students' needs and discourse in the L1 and in the local context.

Purpose: To analyze students' attitudes toward English-Medium Instruction (EMI) classes for nursing students. Methods: From January 23 to January 30, 2020, a survey was conducted using a web-based survey program on student attitudes, satisfaction, and improvement measures for EMI classes. 216 responded to the survey, giving a response rate of 63.7%. Results: The item with the highest score on the attitude toward EMI lectures was 'EMI classes will be of great help to student's future'. The item 'I will try to speak English with my classmates outside of the EMI class if possible' showed the lowest score. Students answered that they need an appropriate educational environment for the smooth operation of EMI classes, fewer students per class and support for group studies

The purpose of this study was to investigate the effectiveness of the differentiated instruction in mathematics by a meta-analysis. Among the studies conducted for last twenty three years, the relevant 49 research articles were selected, 80 effect sizes were calculated for the cognitive domain and 70 effect sizes for the affective domain. Effect sizes were analyzed with school levels, student level, group organization method such as homogeneous vs. heterogeneous, class transfer and adjusting class sizes for each cognitive domain and affective domain. The results are as the followings: In the cognitive domain, the overall effect size of the differentiated instruction produced a medium effect(effect size=0.68, U3=75.17%). The differentiated instruction showed the highest effect size on elementary school and middle school, mid level students, heterogeneous group, class transfer and not adjusted class size. And in the affective domain, the overall effect size of the differentiated instruction produced a low effect(effect size=0.36, U3=65.36%). The differentiated instruction showed the highest effect size on elementary school, mid level students, and heterogeneous group. Thus the differentiated instruction was proved to be effective in mathematics classes.

The purpose of this study is to analyze elementary school students' pre-concept of electromagnet and to investigate effects of instruction through social interactions on conceptual changes of the electromagnet. For the purpose, 108 elementary school students of 3 classes were selected from the 6th grade. They were divided into the control group I, control group II and experimental group. The control group I was treated through traditional instruction on the basis of text book. The control group II was instructed with a modified version of the textbook to help them better understand the concept of electromagnet. The experimental group was treated through instruction on the basis of the above modified version of the text book and social interactions. Conceptual changes on electromagnet before and after the treatment were quantitatively and qualitatively analyzed using the identical test. The students' styles of social interaction were qualitatively analyzed with tape records of their discussions and work sheets. Effects of instruction through social interactions based on radical constructivism on the 6th-grade elementary school students' concept of electromagnet were examined here. The results were described as follows. Firstly, after the treatment, the experimental group was statistically significantly higher in mean values of conceptual understanding and academic achievement than both the control group I and II. Secondly, styles of social interaction in the three sub-groups of the experimental group were qualitatively analyzed, among the threes, high- and medium-level sub-groups were higher in the frequency of linguistic social interaction than the low-level sub-group. Those students who were excellent in communication skills actively participated in linguistic social interactions. In discussions among the three sub-groups, students of the high- and medium-level sub-groups provided explanations or information while those of the other sub-group sometimes were passive by just listening, but in large actively participated in communication. In conclusion, instruction through social interactions was effectively changed in the 6th-grade elementary school students' concept of electromagnet.
