The results revealed that the experimental group performed better on the posttest after giving feedback to their peers. Assessing without time limitation and disruption, correcting writing tasks more precisely, and enhancing lexical and grammatical knowledge were the benefits of assessing peers' writing tasks in Google Docs. Students also held the view that it could help them get familiar with the academic writing principles and how to correct writing tasks.","PeriodicalId":138384,"journal":{"name":"2022 9th International and the 15th National Conference on E-Learning and E-Teaching (ICeLeT)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116445743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When they just have a limited information about the courses, they must rely on general course schedule systems for guidance, but the outcome are inadequate. In this research, we propose a course recommender system based on graph clustering and ant colony optimization to solve the problem. Graph representation, graph clustering, user weighting using ant colony optimization, and rating prediction are the four essential steps in the proposed method. The dataset is first represented as a weighted network based on the degree of similarity between each pair of users. The Pearson-r correlation coefficient is used to calculate the similarity between users. Ratings of users who are most similar to the active user are the goal of the clustering phase. As a result, users in the same cluster have a lot of similarities. Through third step, the Ant colony algorithm is used to weight users (students) with the goal of picking a group of highly correlated users associated with their importance values as target user's neighbor users. Finally, unknown ratings are predicted in the fourth phase by combining the rating values of nearby users with their weights of similarity to the target user.","PeriodicalId":138384,"journal":{"name":"2022 9th International and the 15th National Conference on E-Learning and E-Teaching (ICeLeT)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129284079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within educational games, adaptivity defines automatic adaptation of learning objects based on student's learning styles, preferences, weaknesses or strongest, etc. Recently, machine learning algorithms such as recommender systems and… have been applied to develop personalization add adaptation properties in educational games. In this study, we introduce an interactive educational game developed based on first-grade students' math-books or school learning concepts. In this game, according to the student's profile and evaluation tests, the game evaluates students' performance iteratively. Also, student's learning styles and preferences will be extracted through playing game. Then in each iteration, the system recommends suitable learning objects to a learner based on a trade-off between their skills and the difficulty of the task.","PeriodicalId":138384,"journal":{"name":"2022 9th International and the 15th National Conference on E-Learning and E-Teaching (ICeLeT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130007707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the variety of MOOC courses and their frequent changes make it more difficult for students to identify relevant new information. To pique students' attention, a recommendation system (RS) is used to match the learner with the best learning resources. Most research on recommender system relies mainly on the presence of explicit feedback, while this information is commonly scarce or unavailable in MOOCs. Therefore, in this paper we use implicit feedback which is gathered passively by tracking different sorts of students' behavior to model user positive and negative preferences. We propose using Siamese Neural Networks (SNNs) to extract latent representations of students and courses based on a loss function that gives observed courses a higher preference than unobserved courses. Then, users and courses similarity are determined based on new representations. Furthermore, the other challenge is recommending courses to students with little available interaction data (cold start). To solve this problem, we employ user and course content information, which aids in the creation of more accurate representations as well. We analyze the proposed model on a real dataset obtained from XuetangX-one of China's largest MOOCs-. Experiment results show that the proposed algorithm outperforms numerous baseline algorithms.","PeriodicalId":138384,"journal":{"name":"2022 9th International and the 15th National Conference on E-Learning and E-Teaching (ICeLeT)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124316511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
