  29. 29. 29 Evaluation Proposed Multiple-Choice Questions 31 out of 121 students submitted multiple-choice questions for all subjects not many questions were congruent with the questions of the teacher if questions of the teacher were submitted, these questions were among the best Josef Wachtler, Marco Scherz, Martin Ebner and Maria Grandl, Educational Technology - TU Graz June 26, 2019
  30. 30. 30 Discussion Discussion Josef Wachtler, Marco Scherz, Martin Ebner and Maria Grandl, Educational Technology - TU Graz June 26, 2019
  31. 31. 31 Discussion General students show a better grade point average after than before using LIVE reduced workload of the teacher students could focus on the content of the videos and not on administrative tasks like using an assigned username Josef Wachtler, Marco Scherz, Martin Ebner and Maria Grandl, Educational Technology - TU Graz June 26, 2019
  32. 32. 32 Discussion Learning Approach high correctness rate at the questions because students could watch the videos multiple times students reported that they worked according this workflow: 1. watching the videos 2. answering the multiple-choice questions 3. re-reading the teaching materials, if the student was uncertain about the answer 4. re-watching the videos 5. answering the multiple-choice question with additional knowledge Josef Wachtler, Marco Scherz, Martin Ebner and Maria Grandl, Educational Technology - TU Graz June 26, 2019
  33. 33. 33 Discussion Proposed Multiple-Choice Questions broad range of proposed questions could help to identify the interests of the students adapt lecture accordingly Josef Wachtler, Marco Scherz, Martin Ebner and Maria Grandl, Educational Technology - TU Graz June 26, 2019
