One of the strategies to achieve this is to make use of ICT, within which are educational simulators, as a support resource to facilitate the teaching-learning processes taught in the classroom. The didactic strategy developed in this work was carried out with the PhET (https://phet.colorado.edu) simulator was used to improve the learning teaching of the law of conservation of the subject matter and its relationship with chemical reactions. To evaluate the learnings acquired by students, the Hake factor was determined. In terms of the implementation of this didactic strategy, students demonstrated greater recognition, understanding and appropriation of the knowledge gained about the importance of this law in chemical reactions. This teaching strategy is useful for higher middle-level schools that do not have a school science lab.</p> Yvonne Rodriguez Barocio, Adolfo Eduardo Obaya Valdivia, Yolanda M.

A recommendation system is developed with software engineering methods. Knowledge graph technology is integrated in the system; curriculum knowledge graphs are constructed to solve the problems of semi-structured data storage and knowledge fragmentation. Two kinds of recommendation methods are adopted to achieve the goal of learners' personalized learning, one is Euclidean distance recommendation algorithm based on user behavior graph library, the other is learning mode recommendation algorithm and sequential mode recommendation algorithm based on user session library. The recommendation system maintains the interpret-ability and the accuracy of recommendation based on user historical behavior data; and realizes recommendation based on user session library in the context of lacking users’ historical data.</p> XU Xiaoli, HUANG Hui, WU Mengmeng, LIAO Yu, YUAN Ziheng, WNAG Yingfeng ##submission.copyrightStatement## https://scipg.com/index.php/101/article/view/400 Fri, 09 Apr 2021 00:00:00 +0000
