Deep learning techniques are being unified for decision support in various applications. However, it remains challenging to train robust deep learning models, due to the inherent insufficient labeled data that is usually time-consuming and labor-intensive. Self-supervised learning is a feature representation learning paradigm to learn robust…

Dialogue act (DA) classification plays an important role in understanding, interpreting and modeling dialogue. Dialogue acts (DAs) represent the intended meaning of an utterance, which is associated with the illocutionary force (or the speaker's intention), such as greetings, questions, requests, statements, and agreements. In natural language…

The purpose of this study was to investigate the perception of the experiences of community college students enrolled in a mathematics course with supplemental instruction (SI) attached. This study was conducted at a moderate-sized community college in Maryland. A qualitative research design was used, specifically a systematic approach design.…

Labs have long been considered an important component of physics education. However, while there has been progress in transforming physics education in physics lecture classes to improve student learning, less progress has been made in introductory physics labs. At the same time, the physics community has come to recognize that there is a need to…

Adolescent newcomer students bring a wealth of linguistic and cultural resources to their learning environments--resources that become even more dynamic when combined with those of their peers. While a significant body of research has explored students' deployment of multilingual resources through translanguaging, most of this work does not…

A growing number of studies has shown that collaborative writing tasks facilitate second language (L2) development by providing learners with opportunities to focus their attention on language and to collaborate in the solution of their language-related problems (e.g., Choi & Iwashita, 2016; Storch, 2013; Swain & Lapkin, 1998; Williams,…

A theoretical model of metacognition in complex modeling activities has been developed based on existing frameworks, by synthesizing the re-conceptualization of metacognition at multiple levels by looking at the three sources that trigger metacognition. Using the theoretical model as a framework, this study was designed to explore how students'…

This mixed methods classroom research examined if accountability groups in the lower proficiency levels of a university intensive English program would improve students' language acquisition. Students were assigned partners for the study period with whom they completed assignments inside and outside of class, as well as set goals for use of…

The purpose of this study was to develop an instructional theory for using a class wiki to support collaborative learning in higher education. Although wikis have been identified in theory as one of the most powerful emerging technologies to support collaborative learning, challenges have been revealed in a number of studies regarding student…

Cross-cultural online collaboration has evolved as an inevitable trend that people influenced by globalization cannot neglect. The primary purpose of this study was to discover major factors contributing to productive and effective online cross-cultural collaborative learning for people from diverse cultural backgrounds with varying levels of…

Over the past decade calls for reform in higher education have emphasized that education should become less instructor centered with students taking a more active role in their learning. Moreover, there is increasing pressure on university professors to implement student centered teaching strategies that negate time and place restrictions of the…
