Recommender systems have become one of the main tools for personalized content filtering in the educational domain. Those who support teaching and learning activities, particularly, have gained increasing attention in the past years. This growing interest has motivated the emergence of new approaches and models in the field, in spite of it, there is a gap in literature about the current trends on how recommendations have been produced, how recommenders have been evaluated as well as what are the research limitations and opportunities for advancement in the field. In this regard, this paper reports the main findings of a systematic literature review covering these four dimensions. The study is based on the analysis of a set of primary studies (N = 16 out of 756, published from 2015 to 2020) included according to defined criteria. Results indicate that the hybrid approach has been the leading strategy for recommendation production. Concerning the purpose of the evaluation, the recommenders were evaluated mainly regarding the quality of accuracy and a reduced number of studies were found that investigated their pedagogical effectiveness. This evidence points to a potential research opportunity for the development of multidimensional evaluation frameworks that effectively support the verification of the impact of recommendations on the teaching and learning process. Also, we identify and discuss main limitations to clarify current difficulties that demand attention for future research.

用于教学和学习的教育推荐系统的系统文献综述:研究趋势、局限性和机遇

推荐系统已成为教育领域个性化内容过滤的主要工具之一。那些支持教学活动的人在过去几年中尤其受到越来越多的关注。这种日益增长的兴趣促使该领域出现了新的方法和模型,尽管如此,关于推荐的产生方式、推荐系统的评估方式以及研究内容的当前趋势,文献中仍存在差距在该领域取得进步的限制和机会。在这方面,本文报告了涵盖这四个方面的系统文献综述的主要发现。该研究基于对一组初步研究的分析(N = 756 个中的 16 个,于 2015 年至 2020 年发布)根据定义的标准包括在内。结果表明,混合方法一直是推荐生产的主要策略。关于评估的目的,主要根据准确性质量对推荐者进行评估,并且发现调查其教学效果的研究数量减少。这一证据指出了开发多维评估框架的潜在研究机会,该框架可有效支持验证建议对教学过程的影响。此外,我们确定并讨论了主要局限性,以阐明当前需要关注未来研究的困难。
