The purpose of this study is to find out the effects of learning that has applied instruction module utilizing ICT in project-based learning in elementary science classroom on improvement of the self-directed learning skills and the problem-solving skills. For this purpose, the project based learning instruction module utilizing ICT based was developed and conducted to 2 class consisting of 66 elementary students in the 6th grade to clarify the effects. As a result of the study, first, the instruction module utilizing ICT in project-based learning was effective in improving self-directed learning skills of students. As the subordinate effects of self-directed learning skills it showed improved effects in diagnosing desire to learn, setting goals, basic self-managing ability, selecting learning strategy, durability of practicing learning, making effort for result, and self-examination but it did not show improved effects in figuring out recognition of resources for Learning. Second, it was effective in improving the problem-solving skills of students. As the subordinate effects of problem-solving skills it showed improved effects in problem recognition, information gathering, analysis, thinking prior to dissemination, planning skill, and evaluation but it did not show effect on decision making, implementation & risk-taking and feedback.

This study sought implications for further revitalizing student-centered classes by measuring and analyzing the effects of the operation of major courses applying blended learning for library and information sicence (LIS) students on learning immersion, result achievement, and learning satisfaction. The results are as follows: First, as a result of comparative analysis between the pre and post scores of learning immersion, result achievement, and academic satisfaction after operating the blended learning class, the average score of the post-survey was high. Second, among the factors of learning immersion, significant results were found in academic reasons, academic concentration, interest, and control. In particular, the effect of academic concentration and control was high. Third, among the factors of outcome achievement, significant results were found in achievement motivation, satisfaction, relationship utilization ability, and class attitude. The effect of satisfaction and relationship utilization ability was particularly high. Fourth, both general satisfaction and learning-related satisfaction were very effective in academic satisfaction factors. In sum, it was found that the operation of major courses applying blended learning was effective for LIS students.

There is a growing tendency to consider organizational learning as a mechanism for improving organizations and the rate at which organizations learn becomes perceived as a source for attaining competitive advantage. The objective of this research is to present a two-phase(learning efficient, and learning-effective) organizational modeling methodology based on the cognitive-maps and agents concept, and to describe how the result of the modeling can be used in the organizational learning context.

The objective of this study is to explore basic type of character of humans and to suggest a design method of establishing a spatial construction environment for developing effective learning ability based on such type of character. As a range of research, spatial formative language was deduced and space design strategy for the children was suggested through an analysis of spatial requirements by exploring connectivity depending on features of 9 types of character through Enneagram. As a method of research, a process of suggesting a concrete method after defining an element of spatial construction and deducing a formative language for developing and strengthening effective learning ability for each type of character. As a result of research, the methods of children space design strategy for enhancing learning ability for leadership in a future specific fields were suggested through 9 different type of character with image of case study.

In this paper, we present a effective method to control robotic systems by an iterative learning algorithm. This method is based on the concepts of the learning control law which is introduced in this paper, that is, avoidance of using derivative of system state and ignorance of high frequency influence in system performance. By means of the betterment of performance due to the improvement of estimated unknown information, the learning control algorithm compels the system to gradually approach in desired trajectory, and eventually the tracking error asymptotically converges upon zero. In order to verify its utility, one degree of freedom of manipulator has been used in the experiments and the results illustrate this control scheme is very effective.

This study investigates the effects of written vocabulary exercises on lexical knowledge. Korean university students learning English as a foreign language were randomly assigned to one of four conditions-Condition 1 (having students match word form with word meaning), Condition 2 (having students fill in the blank provided with a list of words), Condition 3 (having students write sentences with the target words), Condition 4 (having students do three practices with the same vocabulary exercise as the condition 1). Each type of exercises in Condition 1, 2, and 3 was designed to classify a different level of mental processing except Condition 4 with multiple encounters of the target words. Learners' vocabulary knowledge of this study was obtained using a format adopted from the Vocabulary Knowledge Scale (VKS) immediately and two weeks later. The findings indicated that: (1) Condition 4 having students do three matching vocabulary exercises was as effective as the condition 3 (one writing exercise) on the immediate learning of word; (2) although there was no significant difference of the effect of vocabulary exercises between Condition 3 and 4, Condition 4 asking students to do three matching vocabulary exercises was the most effective way of vocabulary retention after two weeks.

In the acoustic modeling for large vocabulary speech recognition, a sparse data problem caused by a huge number of context-dependent (CD) models usually leads the estimated models to being unreliable. In this paper, we develop a new clustering method based on the C45 decision-tree learning algorithm that effectively encapsulates the CD modeling. The proposed scheme essentially constructs a supervised decision rule and applies over the pre-clustered triphones using the C45 algorithm, which is known to effectively search through the attributes of the training instances and extract the attribute that best separates the given examples. In particular, the data driven method is used as a clustering algorithm while its result is used as the learning target of the C45 algorithm. This scheme has been shown to be effective particularly over the database of low unknown-context ratio in terms of recognition performance. For speaker-independent, task-independent continuous speech recognition task, the proposed method reduced the percent accuracy WER by 3.93% compared to the existing rule-based methods.

Since the first semester of 2020, domestic and overseas universities mostly provided untact online classes and limitedly provided face-to-face classes due to COVID-19 in operating courses. The convergence subjects provided in undergraduate courses attach importance to contents-centered, design-based, hands-on education, and field experience. In the situation where online education was not revitalized, instructors in charge of convergence subjects had difficulty in developing online class materials, and students' satisfaction with the classes was not high. Especially, a problem was raised that students taking the convergence subjects that included practice had difficulty in communicating with the instructors. We would investigate the present condition of distance learning in domestic universities, which came suddenly due to the global pandemic of infectious disease and make suggestions for effective distance learning in the coming era of Metaverse by emphasizing the interaction and communication between instructors and learners through an analysis of distance learning of a convergence subject.
