Toward Predict the Student Grade with Decision Tree Algorithm
ABSTRACT
With the rapid development of online open courses, it has become a hot issue in educational research to use learning analysis technology to explore online learning characteristics and provide support for the improvement of teaching methods and academic warning. A grade prediction model based on decision tree algorithm according to students’ previous learning behavior is designed in this talk. Firstly, ID3, C4.5 and CART classification algorithm are used to construct the initial grade prediction model for the pre-processed learning behavior data set. Secondly, in order to prevent over-fitting, pruning set is used to conduct pruning on the initial grade prediction model. Finally, the performance of three grade prediction models is evaluated by test data set. Experimental results indicate that the grade prediction model constructed by ID3 algorithm has better performance than that constructed by other two algorithms.

Social Presence’s Effects on Web-based Learning of Interlanguage Pragmatics
ABSTRACT
In the learning community based on computer-mediated communication, social presence is an important concept to assess social interaction under web-based learning environment, and appears to have an effect on online learning experiences in the context of higher education. However, few studies are concerned with social presence’s influence on second language acquisition. This study investigates the effects of social presence during the explicit instruction delivered via micro-blog on ILP (interlanguage pragmatics) learning. Three research questions are addressed: (1) whether students’ social presence correlate with their cognition density of L2 pragmatics, (2) whether students’ social presence correlate with the development of their L2 pragmatics competence, specifically in producing more appropriate expression, more target-like assessment and higher-level pragmatics awareness, and (3) whether students’ social presence correlate with their online learning perceptions, including perceptions on personal relevance, authentic learning, active learning and satisfaction. To address the three research questions, this study adopted qualitative and quantitative research methods. A pretest–posttest design was applied to include two groups of learners who had the same level of English proficiency. The learners received explicit pragmatics instruction and participated online discussions delivered via micro-blog over ten weeks. In light of an extensive quantitative and qualitative data analysis and discussion, results showed that it is effective to build ILP learning environment based on micro-blog, and social presence has positive effects on L2 pragmatics cognitive density, L2 pragmatics competence development and ILP online learning perceptions. The research findings contribute to ILP teaching methodology, ILP web-based teaching design and social networks’ application in the second/foreign language educating.
