Article Citation - WoS: 26Citation - Scopus: 33An Explanatory Sequential Mixed-Method Research on the Full-Scale Implementation of Flipped Learning in the First Years of the World's First Fully Flipped University: Departmental Differences(Elsevier, 2021) Demir, Ömer; Birgili, BengiThis study evaluates the first years of the full-scale flipped learning implementation process that began with an authority innovation-decision at the world's first fully flipped university in terms of departmental differences. The study employs an explanatory sequential mixed-method research. The primary respondents were 69 freshmen enrolled in the Faculty of Education at a private university in Istanbul, Turkey. In addition to student participants, five faculty members were recruited to the study. The primary data was collected through a Likert-type scale on flipped learning, including components on motivation, course structure, and interaction. Pre and post semi-structured interviews and a structured ranking form were also used to support the quantitative data. The findings of the study reveal that the students felt relatively unmotivated when instructed through flipped learning, although were satisfied with the course structure. In general, the students lacked student-student interaction. Due to the nature of the Guidance and Psychological Counseling department, the students faced some difficulties in engaging in all three types of interaction (student-student, student-educator, and student-content). Lengthy and poor-quality videos and students' lack of preparation for classes emerged as major problems in flipped learning. The faculty members complained about the amount of time required for pre-class preparation (i.e., recording flipped videos). This paper discusses how to foster motivation, collaboration, discussion, and interaction in flipped learning in higher education settings so as to guide prospective practitioners.Article Citation - Scopus: 1Optimal Video Length Effect on Flow Experience and Perceived Learning: a Repeated Measure Experimental Design With Randomization(2024) Demir, Ömer; Birgili, BengiVideos are commonly used in education. Benefitting from instructional videos in learning processes empowers students’ academic outcomes. In spite of this, educators have no consensus on optimal video length. There is a need to cease speculations on optimal video length since most of them have been relying only on context-based tips or best practices. Therefore, the purpose of this study is to delve into the optimal video length discussion through the lens of perceived learning and flow experience. We employed repeated measure experimental design with randomization of treatment order for each participant. Twenty-eight university students from two big cities in Türkiye volunteered to participate in the study. Short, medium, and long videos were compared via Friedman test. Results of this study substantiated instructional video length does not seem to affect students’ perceived learning and their overall flow experience. However, they tend to concentrate and focus better on short videos. We call for an end to optimal video length discussion for videos shorter than 10 minutes, especially in terms of learning. The implications relying on the findings were discussed in terms of differences between “thinking to be in flow” and “being actually in flow.” The recommendations are given in detail in the full text.Article Citation - WoS: 1Citation - Scopus: 2The Mediating Role of Instructional Design and Video Length Between Grade Level and Pupil-Content Interaction in Instructional Mathematics Videos on Youtube(Springer, 2024) Demir, Ömer; Birgili, BengiThe use of instructional videos is rampant in education; however, their interaction is limited by weak instructional design. Gagne has never insisted on using his renowned 9 Events of Instruction slavishly in situations as a viable paradigm for utilization in video design. Connecting grade level, video length, and interaction, this study seeks to determine the relevance of Gagne's prescribed 9 event sequence in instructional mathematics videos. We scrutinized 50 instructional mathematics videos on YouTube geared towards middle school pupils ranging between 5th and 8th grades. We used quantitative media content analysis for video analysis. In data analysis, partial least squares were used. Bayesian estimation was also resorted to for cross checking. The data revealed that one-third of Gagne's instructional design steps were not always present: activating prior knowledge, eliciting performance, and finally providing feedback. A mediation analysis between grade level and video length revealed that 6 events fully mediated the association between the two. We also elicited the impact of these variables on affective and behavioral interactions in videos. This study assists in creating an idiosyncratic instructional design model, called Birgili's 8 steps for instructional video design, and in infusing this with a melange of four theories. In contrast with the status quo attesting that the literature abounds with scholarly works touting the shorter is the better mantra, the results substantiated that longer may be better in leveraging video interactions provided that the length is judiciously used to conform to instructional design principles.
