The main aim of this paper is to present results of an experimental test focused on the validity and effectiveness of composed methodology aimed at increasing the student's attention in Virtual Learning Environment. Areas of presented methodology which were subject of our research is students behavior during learning. The behavioral part of methodology is focused on calculating estimated time for reading/learning specific learning material based on mathematical model. The model has been created as linear regression model trained and validated with student's access logs from Moodle instance used at the university. The methodology created by us, which is the subject of the experiment, uses the mentioned mathematical model in order to more optimally calculate the time-on-task and thus assume the time required for the correct understanding of the presented curriculum in the form of e-learning. In this paper, we will focus on confirming the didactic effectiveness of our proposed methodology for monitoring student attention. We describe an experiment with which we verified the proposed methodology. Methodology itself is focused on improving students learning experiences while using e-learning platforms like Moodle.

Knowledge about suicide postvention (KSPV) is an important distal outcome in the evaluation of suicide prevention programs that focus on the bereaved. However, most scales are specifically tailored to the evaluation study in question and psychometric properties are often unsatisfactory. Therefore, we developed the KSPV scale. Scale properties were investigated with Rasch trees, a newly developed method in the framework of item response theory. Additionally, we provide cues for convergent validity. In summary, the scale shows satisfactory properties for assessing KSPV and could be used to evaluate suicide postvention programs more effectively. (Contains 2 tables and 1 figure.)

It is often assumed that persons who develop ocular disease have some form of visual experience that makes them aware of their deficits. However, in the case of peripheral field loss or decreasing vision in dim lighting, as in retinitis pigmentosa, for example, symptoms are more obscure and may not be as easily identified by the persons who have them. Only one questionnaire that evaluates functionally relevant visual distortions has been published in a peer-reviewed scientific journal. Arimura and colleagues (2006) correlated perceptual distortions that are associated with the development of a macular hole with scores on their metamorphopsia questionnaire. Arimura et al.'s 10-item measure contains questions that evaluate far distance vision (such as the perception of telephone poles), intermediate distance vision (such as the outline of a television set), and near vision tasks (reading). The goal of administering this questionnaire to individuals with retinitis pigmentosa was to investigate whether these individuals are indeed experiencing visual distortions or scotomas or both, since no studies have yet addressed this question. Given that only a small number of questions were sensitive enough to detect functional effects in central vision among this group of persons with retinitis pigmentosa who had relatively good acuities (better than 20/60 or 6/18), some of the content will need to be revised to make this measure more informative for both clinicians and rehabilitation specialists.
