A Study on the Research Trends of Smart Learning

Abstract The purpose of this study was to find research trends of smart learning. For this, we identified the research’s characteristics such as the subject or keyword of research, method, data collection, and statistical analysis method. The 2,865 articles published from 1995 to 2013 were gathered from five Korean academic journals related to smart learning. Among them, research keyword, areas, research method, data collection method, and statistical analysis method were analyzed on 596 papers. The findings of this study were as follows: (a) Smart learning papers such keyword likes u-learning, m-learning, and smart-learning were emerging after 2006. Smart learning papers with ICT related topics were highly increased after 2000, but they were decreased after 2006. Smart learning papers with e-learning related keywords were steadily increased after 2000 through 2013. (b) The research field of deign had the highest portion in smart learning research, but managing had the lowest portion. (c) Development was mainly used as a research method. Both questionnaire and experiment were mainly used for collecting data methods. T-test and frequency analysis were mainly used as statistical analysis methods.Key words : Smart learning, Research trends, Research topicsCorresponding author : 051-629-5510, gyunheo@pknu.ac.kr* 2013 .

A Study on the Relationship among Communication Competency, Social Network Centralities, Discussion Performance, and Online Boarding Activity in the Team Based Learning

Abstract The purpose of this study is to find the relationships among communication competency, social network centrality(trust centrality and knowledge sharing centrality), discussion performance, and online boarding activity in the team based learning situation. For investigating this topic, 44 students are participated in the classes of educational technology.

Followings are the results of the research: (a) Communication competency is improved significantly after team based learning. (b) Trust centrality effects significantly on the knowledge sharing centrality. (c) Knowledge sharing effects significantly on discussion performance. (d) Trust centrality effects on the online boarding activity in the team based learning.

A Meta-Analysis on the Effectiveness of Smart-Learning

The purpose of this research was to analyze the effects of smart learning. By using meta analysis method, twenty MA and Ph.D degree papers published from 2006 to 2013 were analyzed and 104 effect sizes were calculated. Followings were the results of the research: (a) Smart learning turned out to be more statistically effective comparing to traditional education. The total mean effect size was .886 and the value of U3 was 66.53%. (b) All effect size of sub dependent variables(ie, academic achievement, learning satisfaction, learning attitude) were also effective by adapting smart learning. (c) The moderated variables likes learner characteristics, learning content, and interaction had high effect sizes. Operation system variable had a low effect size but it was not significant.The purpose of this research was to analyze the effects of smart learning.

A Study on the Structural Equation Modeling of the Relationships among Major Satisfaction, Career Search Efficacy, and Career Exploration Behavior with Marine Science High School Students

Abstract The purpose of this study is to find the structural relationships among major satisfaction, career search efficacy, and career exploration behavior with marine science high school students. For investigating this topic, 524 students were surveyed from the marine science high schools. In order to find out the structural relationships among major satisfaction, career search efficacy, and career exploration behavior, structural equation modeling was used. Followings were the results of the research: (a) Major satisfaction effected significantly on the career search efficacy. (b) Career search efficacy effected significantly on the career exploration behavior

A Study on the Research Trends to Flipped Learning through Keyword Network Analysis

The purpose of this study is to find the research trends relating to flipped learning through keyword network analysis. For investigating this topic, final 100 papers (removed due to overlap in all 205 papers) were selected as subjects from the result of research databases such as RISS, DBPIA, and KISS. After keyword extraction, coding, and data cleaning, we made a 2-mode network with final 202 keywords. In order to find out the research trends, frequency analysis, social network structural property analysis based on co-keyword network modeling, and social network centrality analysis were used. Followings were the results of the research: (a) Achievement, writing, blended learning, teaching and learning model, learner centered education, cooperative leaning, and learning motivation, and self-regulated learning were found to be the most common keywords except flipped learning. (b) Density was .088, and geodesic distance was 3.150 based on keyword network type 2. (c) Teaching and learning model, blended learning, and satisfaction were centrally located and closed related to other keywords. Satisfaction, teaching and learning model blended learning, motivation, writing, communication, and achievement were playing an intermediary role among other keywords.

A Study on the Design and Development of Computer Based Learning and Test System

Abstract The purpose of this study is to design and develop a computer based learning and test system, which supports not only testing learner’s ability but also learning contents with giving feedback and hint. In order to design and develop a computer based learning and test system, Visual Basic dot Net software is used. The system works in three stages: sequential problem solving stage, randomized problem solving stage, and the challenge stage of pass/fail. The results of this study are as follows: (a) We propose the context of design for the computer based learning and test system. (b) We design and develop items display function with sequential and random algorithm in this system. (c) We design and develop pass/fail function by applying SPRT(Sequential Probability Ratio Testing) algorithm in the computer based learning and test system.Key words : Computer based test system, Computer based learning system, Sequential probability ratio testingCorresponding author : 051-629-5970, gyunheo@pknu.ac.kr 2015 .

Autoregressive Cross-Lagged Modeling of the Reciprocal Longitudinal Relationship Between Self-Esteem and Career Maturity

The purpose of the current research was to examine the reciprocal relationship among early adolescents between self-esteem and career maturity from the developmental/longitudinal perspective. Data from 1 to 4 (Grades 4–7) survey waves of the Korea Youth Panel Study, a longitudinal study of Korean youth organized by the National Youth Policy Institute and funded by the government of South Korea, were analyzed using autoregressive cross-lagged (ARCL) modeling. The results indicated (a) a positive autoregressive longitudinal relationship between career maturity and self-esteem over time, (b) no cross-lagged longitudinal relationship from career maturity to self-esteem over time, but a cross-lagged longitudinal relationship from self-esteem to career maturity over time, and (c) no gender difference in the ARCL model with self-esteem and career maturity. Findings hold implications for research and practice.

A Study on the Strategy of Performance Assessment based on Classroom

Abstract The purpose of this study was to search the concept and meaning of performance assessment(PA) in the classroom, and the to proposed some strategies to apply PA.The result of this study was presented below. First, differentiation strategy is necessary in the evaluation goal. Individualization will be an example of differentiation strategy in the evaluation of group goal. Second, various strategies are needed based on the subjects of evaluation. Self-evaluation, peer-evaluation, and small group-evaluation are some examples evaluation for the subjects. Third, there is a need for phase-strategy assessment. For the class associated performance assessment, we have to consider the evaluation activities based on the time likes before (pre), on, and after class. How to select the evaluation task is also one of the key sucess factors for improving the class associated performance assessment.Key words : Performance Assessment, Classroom Evaluation, Evaluation StrategyCorresponding author : 051-629-5510, gyunheo@pknu.ac.kr
