Online educational videos are mostly linear videos that are watched passively with the only means of interactivity to be limited to the navigational buttons used to start, pause and resume the video

Educational Settings• The developed learning environment is used at the Department of
Digital Media and Communication at the Technological Education Institute of Western Macedonia, Greece.
• Autumn semester 2014-2015 to support the theoretical part of the first semester courses – “Introduction to new Technologies in Communication” (5 videos
from YouTube) – “Image and Video editing Principles” (1 video).
• Spring semester 2015 to support the second semester course – “Graphic Design” for both the theoretical part (1 video from
YouTube, Fig. 1) and – the laboratory part (10 videos for learning the vector graphics
software Inkscape).
![Page 28: An interactive video based Environment supporting learning analytics](https://reader034.fdocuments.us/reader034/viewer/2022052318/58eeafbf1a28ab1c2e8b463d/html5/thumbnails/28.jpg)
During the autumn semester 2014-2015 students attending the course “Video and Image editing Principles” were given a video to watch as part of the syllabus
Video length: 30 minutes
Sections were defined for the video and the headers of these sections appeared as a table of contents next to the video (Fig. 2). The video consisted of 14 sections. The sections reflected different topics (e.g., an interview). •Video contained information about the promotional video creation process as well as the professionals involved in this process (script writer, director, video editing specialist, etc.).

Course: Image and Video editing Principles

Educational Settings- Assignment• Students were given an optional assignment that was related to the
video • A questionnaire (20%) that was delivered through Google Forms and a
written assignment (80%) that consisted of several open-ended questions.
• assignment was not incorporated in the video environment but was distributed through the institutional learning management system
• The video content was also included in the exam syllabus
![Page 31: An interactive video based Environment supporting learning analytics](https://reader034.fdocuments.us/reader034/viewer/2022052318/58eeafbf1a28ab1c2e8b463d/html5/thumbnails/31.jpg)
Aim of Analysis
• Understand the activity behavior of the learners with respect to the environment features in use (e.g., table of contents) and other factors that affect the viewing behaviour (i.e. assignment and exams), throughout a semester period.
• The analysis also investigates if more active ways of learning such combining video viewing with parallel completion of a related assignment benefits the learning process.

Temporal Aspects

Does video viewing have better outcomes when accompanied by an assignment?
• Another aspect that was investigated was if video viewing yields better learning outcomes when accompanied by an assignment related to the video content
• The focus is only on the students that viewed the video lesson at least once and participated in the exam.
• Besides the overall exam mark, the student mark on the questions associated to the video (which counted for 50%) was recorded and only this mark is used in the study conducted (“video exam mark – VE mark”. )
![Page 35: An interactive video based Environment supporting learning analytics](https://reader034.fdocuments.us/reader034/viewer/2022052318/58eeafbf1a28ab1c2e8b463d/html5/thumbnails/35.jpg)
Does video viewing have better outcomes when accompanied by an assignment?
• An independent sample t-test was conducted in order to check the effect of the assignment in the final VE mark.
• The sample of students was divided into two groups. The first group was comprised of 30 students who completed the assignment and the second group consisted of 27 students who did not complete the assignment.
• Findings from the t-test indicate that significant differences (p<0.05) exist in the mean scores of the two groups (t=3.289, p=0.002). Students who completed the assignment received higher grades (M=6.63) in the VE mark than those who did not complete the assignment (M=4.09).

Results of analysis• Students viewed the video mainly before the assignment
turn in date and the exam date• Viewing was more ‘turbulent” during the assignment
completion where the Content table feature was used more
• Content table was mainly used to jump to the previous section
• Amongst the students that viewed the video the ones that engaged further by attempting an assignment related to the video content, achieved better in the exam.

Conclusions & Future work• The purpose of this paper was to present a video based
learning environment that – aggregates video content with interactive elements and content
that comes either from the educator or open web resources – Supports learning analytics by providing a data gathering module– Data can be analyzed with packages such as R, Weka, SPSS
• Future Work– incorporate more features into the environment (e.g., discussions,
Branching), use the features within learning scenarios and conduct further data analysis and mining
– Incorporate package functions (R,Weka) in the environment
