The Past, Present, and Future of Research in Distance Education: Results of a Content Analysis.

The articles published in four prominent distance education journals between 1997 and 2002 were categorized and the references cited were tallied. The study provides an opportunity to examine research topics, methods, and citation trends. The results can be used to review current research trends and to explore potential research directions.

Viewing or visualising—which concept map strategy works best on problem-solving performance?

The purpose of this study was to investigate the effects of two types of maps (generative vs. completed) and the amount of prior knowledge (high vs. low) on well-structured and ill-structured problem-solving performance. Forty-four undergraduates who were registered in an introductory instructional technology course participated in the study. Participants were randomly assigned to two treatments that used generative and completed concept maps. Within those treatment groups, participants were differentiated by prior domain knowledge, high or low. Although the high knowledge-generative group outperformed the other three groups on well-structured problem-solving performance, it did not have an effect on ill-structured problem-solving performance.

Design of a cognitive tool to enhance problem‐solving performance

The design of a cognitive tool to support problem‐solving performance for external representation of knowledge is described. The limitations of conventional knowledge maps are analyzed in proposing the tool. The design principles and specifications are described. This tool is expected to enhance learners’ problem‐solving performance by allowing them to represent internal representations externally while they solve problems. Tests of the tool’s efficacy are suggested. Conception d’un outil cognitif pour améliorer la performance dans la résolution de problèmes On décrit la mise au point d’un outil cognitif visant à améliorer la capacité à résoudre des problèmes pour parvenir à représenter extérieurement les connaissances. Pour proposer cet outil, on a analysé les limites des schémas conventionnels de représentation des connaissances. On a ensuite décrit les principes de conception et les spécifications. Cet outil devrait améliorer la performance des apprenants dans la résolution de problèmes en leur permettant de représenter extérieurement des représentations intérieures pendant qu’ils résolvent les problèmes. On suggère des tests pour vérifier l’efficacité de l’outil. Entwurf eines kognitiven Werkzeugs, um das Problem‐Lösen zu verbessern Der Entwurf eines kognitiven Werkzeugs, um den Bereich des Problemlösens bei externer Wissensdarstellung zu unterstützen, wird beschrieben. Die Grenzen konventioneller “Wissenslandkarten” wurden analysiert, um das Werkzeug entwerfen zu können. Grundsätze und Spezifikationen des Entwurfs werden dargestellt. Es wird erwartet, dass dieses Werkzeug die Problem lösenden Leistungen der Anfänger dadurch verbessert, dass es ihnen während des Problemlösens möglich wird, ihre internen Vorgänge nach außen darzustellen. Tests zur Wirksamkeit des entwickelten Werkzeugs werden vorgeschlagen.

Selection of Team Interventions Based on Mental Model Sharedness Levels Measured by the Team Assessment and Diagnostic Instrument (TADI)

Researchers have claimed that successful team performance depends on shared mental models. While there are a number of techniques that have been employed to measure shared knowledge, Johnson and colleagues (2007) developed and validated an instrument for measuring team-related knowledge. This chapter focuses on the application of the Team Assessment and Diagnostic Instrument (TADI). Using the results of this five-factor model (including general task and team knowledge, general task and communication skills, attitude toward teammates and task, team dynamics and interactions, and team resources and working environment), TADI is used to assess the current state of team alignment with respect to the five team-related knowledge factors. Based on the alignment and degree of response, this measure can be used to assess the level of team synergy as well as determine misalignment in specific areas of teammates’ mental models. With this information, team members, leaders, and coaches can better anticipate team problems thereby guiding the selection of team performance interventions ultimately mitigating team problems and improving team learning and performance.

Employment and Vocational Education and Training Policy of German Reunification: Implications for the Unification of South and North Korea

The purpose of the study was to examine the employment and vocational education and training policy in the era of German unification and suggested the lessons and tasks for the unification of Korea. For the achieving the purpose of the study, we analyzed the outcomes and directions during the unified process of Germany. Although the huge amount of unification budget has been spent, the evaluation of the unification Received (August 25, 2017), Review Result (September 8, 2017) Accepted (September 15, 2017), Published (November 30, 2017) 140-742 Graduate School of Sookmyung Women’s Univ., Yongsan-gu, Seoul, Korea email: suzyks@nate.com (Corresponding Author)140-742 Graduate School of Sookmyung Women’s Univ., Yongsan-gu, Seoul, Korea email: ymlee@sookmyung.ac.kr *이 논문은 한국폴리텍대학 프로젝트 “남북통일 준비를 위한 직업교육훈련 정책 연구”의 일환으로 수행된‘이 영민, 김소영(2016). 독일통일 벤치마킹을 통한 폴리텍대학의 남북통일 준비방안.’을 바탕으로 작성되었다. Employment and Vocational Education and Training Policy of German Reunification: Implications for the Unification of South and North Korea Copyright c 2017 HSST 266 outcomes varied among experts and citizens. Main reason was the low performance of employment in spite of the gross expenditure. While the policy made great positive impact on solving the social confusion and decreasing the unemployment rate. In the results, the policy has improved the competitiveness of employment in east Germany. Insight from this research suggested 1) the building of control tower for vocational education and training during the unification of Korea, 2) provision of vocational education and training blueprint, 3) the building of policy plan for developing the industry in north Korea, 4) the preparation of filed-based training, 5) identification of vocational education and training role for the construction of social cohesion and social safety net, and 6) quality assurance of vocational education and training.
