STUDY ON MULTI-GRADED TUTORING PROJECT(MTP) BASED ON SCAFFOLDING THEORY FOR MULTIMEDIA CURRICULUM
YoungMee Choi,MoonWon Choo 한국멀티미디어학회 2007 한국멀티미디어학회 국제학술대회 Vol.2007 No.-
MTP(Multi-graded Tutoring Project) is a designed curriculum needed to perform a high quality project to improve teamwork and major skills for college student majoring in science and engineering. Each student can experience teaching activities as a tutor and learning activities as a tutee in the MTP for four years. Through this curriculum, students arc expected to obtain the capabilities to set up and search the goal of given projects. to make human network among multi-graded students and professionals, which could be critical for finding careers, and to perform graduation projects in a more systematic and co-operative way, resulting in highly-qualified outputs. In this paper. MTP model is described based on scaffolding theory in terms of curricular plausibility and individual-level performance operating in MTP curriculum. The tutoring and evaluation model is described with three dimensional structure composed of participator. changes in learning, and learning processes. The resultant model could be utilized as tools for evaluating thc curriculum set up for the multi-graded project-based teaching environment.
Factors Associated with Depressive Symptoms in the Elderly with Hearing Impairment

Purpose: The purpose of this study was to examine factors associated with depressive symptoms in the elderly with hearing impairment. Methods: We studied 23 hearing-impaired elderly persons aged 60 years or older. The participants underwent audiometric, neuropsychological, and depression assessments. Neuropsychological tests were subsumed in specific cognitive domains (general cognition, semantic memory, processing speed, executive function). The short version of the geriatric depression scale was administered to obtain depressive symptom scores for each subject. Results: First, among audiometric variables, the pure-tone threshold average, sentence-in-noise recognition scores, and hearing handicap scores were significantly correlated with the depressive symptom scores. Second, among neuropsychological variables, the reaction time on the part A of the Korean version of trail making test for the elderly (K-TMT-E), which is reflective of processing speed, was correlated with the depressive symptom scores. Also, the reaction time on the part B of the K-TMT-E, which is reflective of executive function, was correlated with the depressive symptom scores. Lastly, in the stepwise regression analysis, the pure-tone threshold average and the reaction time on the part B of the K-TMT-E were found to be factors significantly associated with depressive symptom scores. Conclusion: Our findings suggest that, for the hearing-impaired elderly, hearing threshold levels and executive function, especially cognitive flexibility are significant factors associated with depression levels.
