Despite the importance of learning to do mathematical proofs, researchers have reported that not only secondary school students but also undergraduate students have difficulties in learning proofs. In this study, we introduced a new toll for learning proofs and explored the reliability and the validity of peer assessment on proofs. In the course of a university in Seoul, students were given weekly proof assignments prior to class. After solving the proofs, each student had to assess other students' proofs. The inter-rater reliabilities of weekly peer assessment was higher than .9 over 90 percent of the observed cases. To examine the validity of peer assessment, we check whether students' assessments were similar to expert assessment. Analysis showed that the equivalence has been quite high throughout the semester and the validity was low in the middle of the semester but rose by the end of the semester. Based on these results, we believe instructors can consider the application of peer assessment on proving tasks as a tool to help students learn.

Higher education is under unprecedented pressure for quality improvement and cost containment/reduction due to global competition and ever-increasing tuition costs. These twin challenges require an unconventional approach, and massive open online courses (MOOCs) and flipped learning have recently emerged as two promising educational alternatives not only to address the current problems but also to direct the future of education. This paper discusses the rapidly changing environment for education, MOOCs, and flipped learning as learning alternatives, the relationship between MOOCs and flipped learning, and course redesign for the implementation of flipped learning. The case of Ulsan National Institute of Science and Technology (UNIST) is also discussed for benchmarking purposes since it has been pioneering an innovative educational methodology for teaching and learning IT-enabled active learning methods from its inception in 2009. It has redesigned almost 70 courses (20% of all the courses to offer) for flipped learning. The objectives of UNIST's educational experiment are three-fold: improving the quality of education for students, improving teaching productivity for the faculty, and containing/reducing education costs for the university.

The emergence of smart devices such as smartphones (e.g., iPhone) and tablets (e.g., iPad) may enhance e-learning by increasing communication and collaborative learning outside the classroom. These devices also facilitate the use of online technologies such as Facebook. However, the adaptation of Learning Management System (LMS) services to mobile devices took longer than social networks or online tools such as Facebook and Twitter have already been long used via smartphone. The main purposes of this study are to explore students' skill levels of LMS (Moodle) and their knowledge of online tools or technologies and then examine if there is a correlation between smartphone use and using of online tools and Moodle in learning. The study conducted among 173 students in the Department of Information Studies (DIS) in Oman, using online survey. The study found that most students demonstrated high levels of accessing course/subject materials and regularly engaging with studies of using LMSs. YouTube, Wikipedia and Facebook were clearly recorded as the most popular sites among students while LinkedIn and Academia.edu were two online tools that had never been heard of by over half of the 142 participants. Emailing and searching are recorded the most popular online learning activities among students. The study concluded that students prefer to use smartphone for accessing these tools rather than using it to access LMSs, while a positive correlation was found between the use of these tools and smartphones, but there was no correlation between smartphones and using LMSs.

현재 대부분의 국내외 대학과 교육 기관에서는 온라인 학습방법을 채택하고 있다. 이에 본 연구는 전통적인 교수법에 대한 상대적 이점으로 많은 온라인 학습도구를 통한 학습효과를 자연지리학 강좌를 중심으로 정량적으로 평가하고자 하였다. 자연지리학 수강자들을 대상으로 실험을 실시하였으며, 인터넷 상에서 정보의 전파 도구로 널리 사용되고 있는 RSS(Really Simple Syndication) 기반의 Podcasting과 Profcast 소프트웨어 프로그램을 이용하여 생성한 동영상 강의가 온라인 도구로 활용되었고, 전통적인 강의실 수업도 함께 병행하였다. 학습효과를 살펴보기 위해, 수강자들이 작성한 강의평가 자료를 분석하였다. 실험은 2007년 봄학기부터 2008년 봄학기까지 동일한 자연지리학 개론 강좌를 대상으로 실시되었다. 본 연구에서 다루어진 실험의 결과에 의하면 온라인 학습 도구는 학습자들의 학습 효과뿐 아니라 수업과 강사에 대한 태도를 긍정적으로 변화시키는 것으로 나타났다. 또한 단순한 PowerPoint 슬라이드만 제공될 때에 비해 교수자의 음성 녹음이 결합된 강의자료가 학습 동기를 높이는데 더욱 효과적인 것으로 조사되었다. 즉, PowerPoint 슬라이드와 같은 시각적인 강의 자료만 제공되는 경우에는 기존의 강의방식과 학습 효과 면에서 큰 차이를 보이지 않았으나, 시각자료에 강의음성이 결합되었을 때, 인터넷 학습자료에 접근하는 빈도가 증가하고 학업성적 및 수업 출석률이 향상되었다. 연구 결과를 바탕으로 온라인과 교실 학습을 병행한 블랜디드형 교수설계 모델이 제안되었다.

Purpose: To understand the students' level of recognition of online classes in the Department of Dental Technology and to provide the basic data for designing online classes based on the dental technology course. Methods: A survey was conducted among the students of the dental technology department. The collected data was analyzed with the SPSS ver. 25.0 program. To ensure a reliable verification, the α=0.05 significance level was used. The t-test and analysis of variance were also performed. Results: The students' level of recognition of online classes in the Department of Dental Technology is shown in the rate of recognition for video-based classes for both the theory and experiments. Students displayed high positivity with the video-based learning as it is repeated learning that is not affected by the limitations of time. In addition, video-based learning is highly beneficial in terms of convenience, satisfaction, and achievement for learning. Conclusion: Based on the results, video-based learning is a highly positive learning type for students. It was also recommended that the Department of Dental Technology should offer a post-COVID-19 online class to include the blended methods of a face-to-face class and video-based learning.

This qualitative study investigated different interaction patterns in an online discussion. The data was collected from asynchronous discussion occurred in a graduate course. The data analysis methods include inductive analysis and mapping strategy. The results of the study suggest three layers of interaction: response sequences, interaction amongst participants, and concept map of messages. The visualization of response sequences enabled the researcher to discover complex and dynamic interaction patterns amongst participants. The many-to-many communication feature of online discussion does not always enable direct one-on-one interaction between two participants. Rather, one message contributed to multiple threads in the stream of conversation. In terms of interaction amongst participants, the interaction amongst participants, as indicated in the data, the messages also bind each participant and consequently a group(s) of participants together. It appears that the contribution of one message may not only enable a response to one participant, but also connect many participants to each other. The concept map of messages proposes that response sequences and interaction amongst participants can also be viewed between concepts within messages in the discussion. On the surface, the messages posted by individuals are linked by the system in a linear fashion as they are posted. However, the interaction extends to collaborative conversation amongst participants. Ultimately, a conceptual network of interrelated ideas including multiple perspectives is built in asynchronous discussion.

We propose and execute an introductory engineering course for investigating the history of technology and the philosophy of technology. Soft engineering, to explore proper technology and appropriate ways of exercising engineering, has been explored. Creative cases for technology are presented following the most creative, successful periods-the ancient greece, the Renaissance and Silicon Valley era. Ancient greek technology has been investigated in terms of "techne" with the origin of technology and/or art, and their equivalences. The Renaissance period has been investigated in terms of "Uomo universale (polymath)" with Firenze geniuses. The successful drives for the Silicon Valley creativeness have been investigated following "entrepreneurship". To overcome the difficult goal to grasp course subject-technology issues, we take a stance as a tourist guide and tourists utilizing offline onsite experiences and online informations. Categorized course materials are surveyed at the beginning of each period and presented following the preferences of the students to maintain the students' interests. Team efforts including group discussions and project executions have been encouraged to seek the aspects of creativeness and/or technology. This paper summarizes the 3-lecture experiences over 2 years for Korean students and/or foreign students conducted at Pusan National University.
