Özet: This study, which aimed at determining the design principles towards the learner model in adaptive online learning environments, employed relational screening model. Determination of the principles was performed in two phases which are relative importance and robustness in the findings. Modified online Delphi method was utilised to develop the principles and to determine the relative importance. In order to assess the robustness in the findings, for the analysis of the data that were obtained by literature review, content analysis and evaluation criteria for the robustness of the findings was used. In the study, which involved a predefined and more structured first lap of survey, the responses of 90 experts (92%) were considered valid and they constituted the study group. During the first lap of the study, 17 principles were identified by utilising arithmetic mean, first quartile deviation and standard deviation, and the Delphi method ended after the consensus of the experts on 15 principles after four laps. Furthermore, the values of reliability analysis (Croanbach Alpha) and intraclass coefficient of correlation (ICC) of the principles were calculated. In accordance with the principles which were determined by using Delphi method, 480 studies related to learner model were analysed by using content analysis, and categorical assessment was done by considering the robustness in the findings. The criterion for the relative importance of the experts showed almost excellent agreement on all 13 principles and significant agreement on 2 principles. After the categorical evaluation of the robustness in the findings, it was noted that 14 principles showed strong research support and 1 principle showed moderate (sufficient) research support. Moreover, the agreement on principles between the observers (ICC=.926) was found high. The principles obtained through the study indicate the common inclinations both in the literature and of the domain experts.
