Abstract:
1. A recommender system for recommending an educational game to be used by a group of at least two students, the system comprising: at least one tangible processor; and a memory with instructions to be executed by the at least one tangible processor for: receiving a request to recommend an educational game to use with a group of at least two students; accessing student data relating to the at least two students including granular assessment data, wherein the granular assessment data includes a result of at least one assessment administered to respective students of the at least two students, wherein each assessment of the at least one assessment includes a plurality of problems for assessing each of the at least two students and the result includes an independent evaluation of each respective problem of the plurality of problems; associating each of the at least two students with a D-dimensional vector encoding the granular assessment data for that student, the vector including values indicative of an evaluation of each answer to D respective problems, wherein the value for each of the D problems is +1 for a correct answer and −1 for an incorrect answer; determining a similarity of a first student having an associated vector u and a second student having an associated vector v, and applying the formula 0.5*(1+cos(u,v)) to u and v; comparing the similarity of the student data for the at least two students; assigning the at least two students as belonging to one of a homogeneous and heterogeneous group based on the similarity; selecting an educational game from a plurality of educational games, wherein the selecting includes: in response to the at least two students being assigned to the heterogeneous group, selecting the educational game based on various levels of mastery for the academic area being exercised; and, outputting the selected game.
