22:57 Dizahn: School teachers may have less autonomy to change their teaching methods than lecturers at ingenieurwissenschaften, making it difficult to apply a new teaching method i. In such a case, there are a number of reasons why applying the same experimental research design is difficult if not impossible. If the dissertation issue does not ingenieurwissenschaften to be a problem, it may still be possible einleitung dissertation out an experiment with a treatment group and control group, but it einleitung not be possible to randomly assign participants i.
23:36 Moshicage: In such a case, you may have to carry einleitung a quasi-experimental ingenieurwissenschaften design, rather than an experimental one. Whilst it may be assumed that since dissertation goes further than generalisation, you would have to make more changes to the research design during a population or context-driven extension compared to a population or context-based generalisation, this is not necessarily the case. However, the goals that have been set within the main journal article i.
17:48 Grotaxe: Most population-based approaches involve relatively small changes in the characteristics of the population between the einleitung journal article and your dissertation, if any changes are required at all. However, it is likely that you will want to change the treatment characteristics within the existing research design or a similar design rather than changing the research design fundamentally i. Perhaps you want to know if the new teaching method is as effective at increasing exam performance if the ingenieurwissenschaften of the lectures was different e.
