On the one hand, resources may be limited; at the other hand support is time-consuming. One solution for this problem is to let peer students answer questions of fellow learners. In our approach the analysis of documents and the identification of appropriate and available persons in the Learning Network are combined to bring students together in a so-called Ad-Hoc Transient Community. Experiments demonstrate that, indeed, the use of Latent Semantic Analysis of documents combined with the identification of peers with appropriate tutor-suitability is effective. However, the possibilities to test these technologies and their underlying model for the selection of capable peers across different educational settings are limited. To this end, this simulation has been built. The aim is twofold: 1a) to replicate the first experiments that have been carried out with the system and in that way to validate the model of tutor suitability. 1b) to enhance the model for tutor-suitability, taking into account the factor of network dynamics. The simulation allows new learners to enter network and allows learners to formulate individual goals. Thus, we are able to track the tutor suitability in different educational contexts. 2) To obtain information about interactions that take place between learners in a learning network Description: Van den Berg, B., Van Rosmalen, P., Sloep, P.

It is mainly used to observe and compare the “variety” and the “length” of learning paths in a Learning Networks. In order to run the analysis tool you have to create a control group (cc-data.txt) and experimental groups file (ec-data.txt). Please keep the semantic of the present files like: User ID "Username" Course ID 80 "Username" 23 80 "Username" 26 87 "Username" 23 The data is ordered according to the completion of the courses. Thus, the learner that first finished a course stands on top of the list. All other completed courses are listed according to the time stamp they were successfully completed.

A method section describes hy-potheses for the simulation study and its setup of each step. Netlogo is used to perform the simulation runs. The outcomes of such runs validate the version of the conceptual simulation model in that step, and guide further articulation of the conceptual simulation model. Our study started with a focussed expert discussion in which variables, their relationships, and associated literature with existing re-search were identified as input for all steps. In the first step, focus is given towards simplicity. The second step focuses on more reality, whereas the third step focuses on practical implementation issues. Each model will be elaborated in three parts: model variables, measurement variables, and recommendation strategies, followed by the setup of the simulation. Finally, conditions and treatments that are included in the simulation runs of that step will be described. Each conceptual simulation model is largely in line with the model described by Koper (2005). The main goal of the final version of the conceptual simulation model is that it represents the minimized set of LA- and learner characteristics that can support the included RS. Every condition in the simulation was replicated 12 times (i.e., N = 12 runs) to justify the use of classical statistic techniques on resulting data (Law and Kelton, 2000: p. 496), analyzed with SPSS version 15. Each condition included three treatment groups (O, P, OP) and one control group (C). Six conditions were included: goal (2) x sub domain (3). A low-end goal and a high-end goal were taken (see Tables 3.3.3 and 3.3.4). Either, 2, 3 or 4 sub do-mains were taken as they were all regarded to be representative for studies in higher distance education. In all six conditions, each group included 250 learners that could choose from 400 LAs. For all runs, only ‘graduates’ or ‘dropouts’ were allowed after run length. In other words, no participants were ‘still studying’ after run length. To check the robustness of the conceptual simulation model other conditions have been simulated as well. 2008-09-13T11:02:09Z http://hdl.handle.net/1820/1212 Title: Personal Recommender Simulation Authors: Van den Berg, Bert; Nadolski, Rob; Drachsler, Hendrik; Berlanga, Adriana; Hummel, Hans; Koper, Rob; Sloep, Peter Abstract: The main goal of our project is to research and develop technologies that support users in Learning Networks. One of the questions in this research is how to tackle the problem of the difficulty for learners to navigate through the network: what is the most effective way to reach the learning target or which course can be studied best after finishing a particular one? The aim of this program is to simulate recommendations (strategies) of learning actions (LA's) for learners in a learning network with different (sub) domains, targets, preferences and competences. It is used to explore and to research the effectiveness of different recommendation strategies in various settings.
