Article Citation - WoS: 7Citation - Scopus: 6An Intervention Framework for Developing Interactive Video Lectures Based on Video Clickstream Behavior: a Quasi-Experimental Evaluation(Taylor & Francis, 2022) Yürüm, Ozan Raşit; Yıldırım, Soner; Taşkaya Temizel, TuğbaThe purpose of this study is to develop an intervention framework based on video clickstream interactions for delivering superior user experience for video lectures. Apart from existing studies on data-driven interventions, this study focuses on video clickstream interactions to identify timely interventions for creating interactive video lectures. First, a framework was developed through an exploratory experiment, in which 29 students’ clickstream behaviors were tracked on an online platform and then individual interviews were held with 17 of the students and a subject-matter expert. The framework shows how click types are transformed into interactive elements with five question types (where, why, which, how, what). It includes click types, click reasons, interventions, actions, and interactive elements. Then, a quasi-experimental study was performed with 18 students to investigate the effect of the proposed framework on the students’ satisfaction and engagement. The results showed that students’ satisfaction significantly increased for interactive videos created using the proposed framework when motivation was controlled. In addition, students’ frequency to go back to important points decreased significantly in interactive videos, whilst students’ frequency to skip unimportant points increased significantly in interactive videos. In conclusion, the proposed framework can be used to transform linear videos to interactive videos.Conference Object Citation - Scopus: 6A Comprehensive Evaluation of Agile Maturity Self-Assessment Surveys(Springer Verlag, 2018) Yürüm, Ozan Raşit; Demirörs, Onur; Rabhi, FethiAgile methodologies are adapted by growing number of software organizations. Agile maturity (also called agility) assessment is a way to ascertain the degree of this adoption and determine a course of action to improve agile maturity. There are a number of agile maturity assessment surveys in order to assess team or organization agility and many of them require no guidance. However, the usability of these surveys are not widely studied. The purpose of this study is to determine available agile maturity self-assessment surveys and evaluate their strengths and weaknesses for agile maturity assessment. An extensive case study is conducted to measure the sufficiency of 22 available agile maturity self-assessment surveys according to the seven expected features: comprehensiveness, fitness for purpose, discriminativeness, objectivity, conciseness, generalizability, and suitability for multiple assessment. Our case study results show that they do not satisfy all of the expected features fully but are helpful in some degree based on the purpose of usage.
