The purpose of this study is to design a LMS(Learning Management System) dashboard for instructor feedback support based on learning analytics and to apply a LMS dashboard incorporating such taxonomy which allows an instructor to give a student personalized feedback according to the class content and a student's traits. In the dashboard design phase, usable instructional data were selected from LMS based on feedback taxonomy in terms of learning analytics. Two validity tests were conducted with 8 instructional technologists over 8 years of experience, and were revised accordingly. The final dashboard screen has three parts: A comprehensive analysis screen to provide appropriate feedback based on instructor feedback taxonomy analysis, a summary screen for learner analysis, and a recommended feedback guide screen. Detailed analysis information are provided through other dashboards that are displayed in eight screens: login analysis, learning information confirmation analysis, teaching materials learning analysis, assignment/tests, and posts analysis. All of these dashboards were represented by analysis information and data based on learner analytics through visualization methods including graphs and tables. The implications of educational utilization of the dashboard for instructor feedback support based on learning analytics and the future researches were suggested based on these results.

The purpose of this study was to investigate the effect of donning of a hard insole in patients with hallux valgus. Fourteen subjects were selected from patients with foot pain at Lee Chang-Heon Foot Clinic from August 4,2000 to September 15, 2000. The hallux valgus angle and the first-second intermetatarsal angle were radiographically measured before and after donning the hard insole. Based on these two kinds of angles, a mild hallux valgus deformity group was characterized by the hallux valgus angle of less than 20 degrees, and a moderate hallux valgus deformity group was characterized by the hallux valgus angle of 20 to 40 degrees. After three weeks with the hard insole donned, the foot angles of the patients with hallux valgus were measured again. The data were analyzed by Wilcoxon signed ranks test, and the following results were obtained: 1) After the trial, both mild hallux valgus deformity group and moderate hallux valgus deformity group demonstrated that the hallux valgus angles were significantly decreased. 2) After the trial, mild hallux valgus deformity group demonstrated that the first-second intermetatarsal angle was significantly decreased. 3) After the trial, moderate hallux valgus deformity group demonstrated that the first-second intermetatarsal angle was not significantly decreased. The above findings revealed that according to donning hard insole, the hallux valgus angles of mild and moderate hallux valgus deformity groups and the first-second intermetatarsal angle of mild hallux valgus deformity group were significantly decreased. The results of this study have some limitation for generalization due to the limited number of subjects. Further studies are needed to evaluate the effect of hard insole on hallux valgus with more precise laboratory equipments and measurements in patients with hallux valgus.

Based on the results of the research, domestic universities selected the emerging technologies that are likely to be utilized for future education innovation, and presented appropriate teaching and learning measures when they are expected to be introduced to domestic university sites and when to utilize the emerging technologies. This study is meaningful in that it presents practical and field-oriented teaching methods for the latest technologies in the educational use of emerging technologies for future education innovation in domestic universities. Based on the results of this study, we expect to promote diverse educational innovation and empirical research in universities.

Learning Analytics Framework on Metaverse

임성태,김은희,변호승 한국교육공학회 2023 Educational Technology International Vol.24 No.2

The recent development of metaverse-related technology has led to efforts to overcome the limitations of time and space in education by creating a virtual educational environment. To make use of this platform efficiently, applying learning analytics has been proposed as an optimal instructional and learning decision support approach to address these issues by identifying specific rules and patterns generated from learning data, and providing a systematic framework as a guideline to instructors. To achieve this, we employed an inductive, bottom-up approach for framework modeling. During the modeling process, based on the activity system model, we specifically derived the fundamental components of the learning analytics framework centered on learning activities and their contexts. We developed a prototype of the framework through deduplication, categorization, and proceduralization from the components, and refined the learning analytics framework into a 7-stage framework suitable for application in the metaverse through 3 steps of Delphi surveys. Lastly, through a framework model evaluation consisting of seven items, we validated the metaverse learning analytics framework, ensuring its validity.

It has been reported that Tonsillectomy & Adenoidectomy(T & A) resulted in the change of voice by structural changes directly to the vocal track. We studied the effect of T & A on the voice of patients comparing the pre-operative to the post-operative voice. It was performed using a Computerized Speech Lab(CSL50) which is currently used as a method for voice analysis. Forty-five patients who had T&A, aging from 3 to 42 years old, took part in studies and wert evaluated for voice changes and the degree of formant changes of four basic vowels, /a/, /i/, /o/, and /u/. They were evaluated pre-operatively and post-operatively one month later using MDVP, CSL program of CSL50. The results obtained were as follows ; In using MDVP, there were some differences between pre-operative and post-operative shimmer measures within the normal range but other acoustic measures(Fo, jitter, NHR) show no significant differences(p>0.05). F3 of /a/ and /o/ were significantly decreased(p<0.05) and F2, F3 of /i/ were increased(p>0.05) in patients who only had Tonsillectomy in doing CSL spectrogram. For the patients who had T & A, Fl and F3 of /a/, F3 of /i/, Fl, F2 and F3 of /o/ were decreased with significant increase in F1 and F2 of /i/(p<0.05).

This study analyzes the live online learning effects and acceptance perception of civil servants as face-to-face classroom training is cancelled or reduced due to the spread of Covid-19 and converted to live online learning. The survey results of 2,310 participants were analyzed by using a survey tool(The survey consisted of a total of 11 areas and 33 items) for the effectiveness of live online learning at A major government training institute. In addition, using the Two-stage Cluster, three groups were derived: the upper, middle, and lower levels of the perception of live online learning effectiveness. As a result of analyzing learner characteristics for curriculum period, gender, age, working period, and grade based on the derived three groups, there was no significant difference in live online learning effectiveness only in the gender factors. As a result of the main research, it was confirmed that in the age, those in their 40s had a high proportion of the upper group of live online education effectiveness, which positively recognized the live online live effectiveness. On the other hand, it was analyzed that those in their 20s negatively perceived the effectiveness of live online learning as the proportion of live online learning effectiveness was high. In addition, due to the characteristics of the grade, the lower the grade, the more positively the live online education effectiveness was recognized, and the higher the grade, the more negative the live online education effectiveness was recognized. These findings suggest that it is important to design a curriculum in consideration of the learner's main characteristics.

In addition to the development of digital devices in the fourth industrial revolution phase, the use of educational support systems, such as academic performance management programs, learning management systems, and learning diagnosis systems, was common and activated in the internal and external universities. With the accumulation of huge amounts of educational utilization data on the basis of this smart education environment, the ability to create new values is becoming an important factor in the innovation of university education. The results of a survey of 579 undergraduates collected through the MOOC education requirements survey and self-directed capacity measurement conducted by University C showed that the first, self-directed learning factors analysis resulted in learning goal orientation, learning strategy and learning persistence, and the second, the group characteristics were identified according to the classification of the upper, middle and lower three groups. Third, the differences in the level of MOOC awareness and educational needs of the classified groups were analyzed, and finally, simulations of the sample learner were conducted based on the results of this data mining analysis model. Based on the results of this study, when new learner data is entered later, the data mining model will automatically categorize the group types of self-directed learning characteristics and present an education strategy for each individual learner. In addition, the data mining model presented in this study has important implications in that it enables educational diagnosis and prescription for individual learner based on information derived from the actual group of learners who want to give teaching and learning prescriptions.
