What's in It for Me? Incentives,Learning, and Completion in Massive Open Online Courses     

Todd D. Reeves  Andrew A. Tawfik  Fortunata Msilu  Irfan Şimşek 《Journal of Research on Technology in Education》2017,49(3-4):245-259

This study investigated the distribution of incentives (e.g., certificates, badges) for massive open online course (MOOC) completion, and relationships between incentives and MOOC outcomes. Participants were 779 MOOC students internationally who participated in at least 303 different MOOCs offered by at least 12 providers. MOOC participants most commonly intended to receive, and in actuality received, free and paid course certificates of completion; other incentives (e.g., digital badges, postsecondary credits) were far less common. In addition, MOOC participants' intentions to receive both free and paid certificates were consistently and positively related to perceived learning and course completion, net other factors. (Keywords: massive open online courses, MOOCs, motivation, incentives, microcredentials, certificates of completion)  相似文献   

A Cross-Age Study of the Understanding of Three Genetic Concepts: How Do They Image the Gene, DNA and Chromosome?     

Arzu Saka  Lale Cerrah  Ali Rıza Akdeniz  Alipaşa Ayas 《Journal of Science Education and Technology》2006,15(2):192-202

The study was carried out with 175 Turkish students by using drawings at different ages understanding of gene, DNA and chromosome concepts. Students from 8th, 9th, 11th grades and, science and biology student teachers were simply asked to draw the structure of gene, DNA and chromosome in a cell and also to give explanations about these three concepts. Differences in understanding between the age groups were found to be significant for the concepts of gene and DNA. None of the groups exhibit sound understanding and regardless of the age levels, students in all groups had alternative ideas about the three concepts investigated.  相似文献   

Machine learning-enabled multiplexed microfluidic sensors     

Sajjad Rahmani Dabbagh  Fazle Rabbi  Zafer Doan  Ali Kemal Yetisen  Savas Tasoglu 《Biomicrofluidics》2020,14(6)

High-throughput, cost-effective, and portable devices can enhance the performance of point-of-care tests. Such devices are able to acquire images from samples at a high rate in combination with microfluidic chips in point-of-care applications. However, interpreting and analyzing the large amount of acquired data is not only a labor-intensive and time-consuming process, but also prone to the bias of the user and low accuracy. Integrating machine learning (ML) with the image acquisition capability of smartphones as well as increasing computing power could address the need for high-throughput, accurate, and automatized detection, data processing, and quantification of results. Here, ML-supported diagnostic technologies are presented. These technologies include quantification of colorimetric tests, classification of biological samples (cells and sperms), soft sensors, assay type detection, and recognition of the fluid properties. Challenges regarding the implementation of ML methods, including the required number of data points, image acquisition prerequisites, and execution of data-limited experiments are also discussed.  相似文献

The immediate impacts of preschool attendance on Turkish children’s mathematics achievement     

Durmuş Aslan  Yaşare Aktaş Arnas 《Educational studies》2015,41(3):231-243

This study was conducted to investigate the immediate impacts of preschool attendance on Turkish children’s mathematics achievement. The participants were 200 children who attended or did not attend preschool. The number and operation task and the geometric shapes sorting task were used as the data collection tools. The children who attended preschool performed significantly better on the number and operation task and the geometric shapes sorting task than the children who did not attend preschool. Indeed, the multivariate regression analysis demonstrated that preschool attendance is the most important predictor of the success of children in number and operation task and the geometric shapes sorting task.  相似文献

Meeting in school: Cultural diversity approaches of teachers and intergroup contact among ethnic minority and majority adolescents     

Savaş Karataş  Katharina Eckstein  Peter Noack  Monica Rubini  Elisabetta Crocetti 《Child development》2023,94(1):237-253

This study investigated the associations between cultural diversity approaches endorsed by teachers and adolescents' positive and negative intergroup contact in schools. Participants were 984 adolescents (M_age = 14.66; 62.7% female; 24.8% ethnic minority) involved in a three-wave longitudinal study between 2019 and 2020. Results highlighted that perceived equal treatment by teachers was related to higher positive and lower negative contact over time. However, perceived support for contact and cooperation and interest of teachers in children's cultural background were not related to either positive or negative contact over time. Importantly, the results were replicated across ethnic minority and majority adolescents. This study provides novel insights into the key role that teachers can play in promoting cultural diversity approaches to facilitate harmonious intergroup interactions in schools.  相似文献
