65. Driving High Inclination to Complete Massive Open Online Courses (MOOCs): Motivation and Engagement Factors for Learners

Author

Chaw, Lee Yen and Tang, Chun Meng

Abstract

Today, online learning is prospering from the widely available and easily accessible connection to the Web. Massive open online course (MOOC) platforms such as Coursera, edX, and Udemy have made available several thousands of short courses at several difficulty levels in a wide variety of disciplines, ranging from business, computer science to literature, for learners to select from. Learners who are looking to earn credentials for career advancement or personal interest would find MOOCs attractive not only because of the time and place flexibility these courses offer, but also because of the free enrollment or the very small certificate fee upon completion, as well as the emergent recognition these courses are receiving for their high quality learning delivery from leading educational institutions. Learners who enroll in a MOOC would typically need to participate in various learning activities and complete a few assessment tasks to complete the course. However, it has been commonly reported that the completion rates of MOOCs are low. Based on the common notion that when learners are more motivated to learn, they are likely to better engage in learning and have a higher likelihood to complete a MOOC, this study adopted the Motivation and Engagement Scale (MES) by Martin (2007, 2009) to collect responses from university students to examine whether positive motivation resulted in positive engagement; whether negative motivation resulted in negative engagement; and how positive or negative engagement swayed learners' inclination to complete a MOOC if they were to enroll in one. Findings show that there was a statistically significant positive relationship between positive motivation and positive engagement, between negative motivation and negative engagement, and between positive engagement and inclination to complete a MOOC. However, the relationship between negative engagement and inclination to complete a MOOC was statistically not significant. Findings of this study can be useful to MOOC providers and learners in their effort to develop strategies to increase completion rates of MOOCs.

Abstract

Single-molecule FRET (smFRET) has become a mainstream technique for studying biomolecular structural dynamics. The rapid and wide adoption of smFRET experiments by an ever-increasing number of groups has generated significant progress in sample preparation, measurement procedures, data analysis, algorithms and documentation. Several labs that employ smFRET approaches have joined forces to inform the smFRET community about streamlining how to perform experiments and analyze results for obtaining quantitative information on biomolecular structure and dynamics. The recent efforts include blind tests to assess the accuracy and the precision of smFRET experiments among different labs using various procedures. These multi-lab studies have led to the development of smFRET procedures and documentation, which are important when submitting entries into the archiving system for integrative structure models, PDB-Dev. This position paper describes the current 'state of the art' from different perspectives, points to unresolved methodological issues for quantitative structural studies, provides a set of 'soft recommendations' about which an emerging consensus exists, and lists openly available resources for newcomers and seasoned practitioners. To make further progress, we strongly encourage 'open science' practices.

98. Guiding Students to Understand the Nanoscale Charge Transport by the Mechanically Controllable Break Junction Technique

Author

Ye, Yiling, Tang, Chun, Zhang, Chengyang, Dong, Gang, Liu, Junyang, and Hong, Wenjing

Abstract

Fabrication of molecular devices will meet the demands of the miniaturization of traditional electronic devices. Although microfabrication based on the complementary metal-oxide-semiconductor process can fabricate high-quality single-molecule devices, the cost is high, leading to a challenge to provide a hands-on experiment in the teaching practice of charge transport through single-molecule devices. Here, we demonstrate the low cost and simple procedures associated with a mechanically controllable break junction (MCBJ) technique to fabricate single-molecule devices. On the basis of the MCBJ technique, the conductance of gold-gold atomic contacts and single-molecule junctions can be readily characterized. The teaching practice helps students understand charge transport at the single-molecule level, that is, the quantum tunneling mechanisms. Moreover, the MCBJ technique study provides students the opportunity to develop interdisciplinary thinking, which is vital for understanding, designing, and developing single-molecule electronics.
