In the academic year 2020-2021, students who had been accepted onto a university in Turkiye began their studies with the use of emergency remote teaching (ERT). The aim of this study is to examine the causal relationship between academic achievement, online course satisfaction, attitudes towards online learning and knowledge sharing behaviors of these novice university students in terms of the emergency remote teaching process. This research was designed to make use of correlational research methods. The study group consisted of 437 freshmen students studying in the Faculty of Education at a public university in Turkiye. Research data were collected using the Knowledge Sharing Behavior scale, the Online Course Satisfaction scale, the Online Learning Attitude scale, and a learning achievement test. Research data were analyzed using descriptive statistics, Pearson correlation analysis, and path analysis. The results showed that general acceptance, knowledge receiving, individual awareness and perceived usefulness significantly affected online course satisfaction. On the other hand, knowledge giving and application effectiveness factors did not significantly affect online course satisfaction. It is noteworthy that individual awareness, which compares face-to-face teaching activities with ERT to identify the preferences and awareness of the students, had a negative impact on their satisfaction. Finally, it was determined that online course satisfaction had a significant but low-level effect on learning achievement. In order to increase student satisfaction with regard to the ERT process, it is recommended that the university makes the opportunities more visible and provide support for students' acceptance of the process. Future avenues and precautions about designing the ERT courses have been suggested in light of the research findings.

This study aimed to evaluate the Online Flipped Classroom (OFC) instruction process in the context of Transactional Distance (TD) and Cognitive Load (CL). The study was conducted using a mixed-methods design. The participants were nine graduate students. One of them participated in the process asynchronously and seven of them participated synchronously, and the one member was irregular. Transactional Distance Scale and Subjective Rating Scale were used to collect quantitative data. Interviews were conducted to gather qualitative data related to OFC instruction process. All of the TD measurements for the asynchronous and irregular students were low. The synchronous students' TD measurements were low when OFC began, becoming very low later on. The asynchronous student felt cognitive load during some of the OFC activities. Synchronous and irregular students felt the cognitive load during almost all the OFC stages. The future studies may focus on measuring the types of CL and collecting qualitative data to determine the CL type may contribute to the literature.

The purpose of this study, with reference to Community of Inquiry, is to evaluate the comparative effectiveness of Learning activities based on Online Inquiry differentiating as Open and Guided Inquiries. This study employs mixed research method and explanatory design. The data were collected with the Community of Inquiry Index and the Student Process Survey. According to the Community of Inquiry index results, scores of all guided inquiry students in terms of the scale were higher at a statistically significant level than those of open group. Similarly, regarding the subscales of community of inquiry index teaching presence and cognitive presence factor scores were higher in favor of the guided inquiry students. There is no significant difference between the social presence scores of the groups. Obtained qualitative data also support this result. According to these findings, we can arrive at the conclusion that, within the scope of Community of Inquiry, the students in the guided inquiry group had a more efficient working process than the students in the open inquiry group.
