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

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

Purpose: This study attempts to close the research gap created by the fact that existing studies neglect the problem of how effectively agricultural professors from different European countries communicate. The aim is to identify similarities and differences in the numbers of agricultural professors perceived by students as engaging in verbal and nonverbal immediacy communication.

Methodology: An online survey was conducted among students of agricultural universities from Austria, Slovenia and Albania.

Findings: The results show that professors of agriculture from Austria, Slovenia and Albania should generally not be satisfied with their own communication patterns and should thus try to improve their communication. The result also reveals cultural differences in the shares of agriculture professors employing different communication patterns in Austria, Slovenia and Albania. Compared to Austrian and Slovenian students, their Albanian peers perceive that most of their professors use nonverbal immediacy communication. According to Austrian students, the majority of their professors use verbal immediacy. On the contrary, Albanian students assessed that some of their professors employ verbal immediacy.

Practical Implications: The results show the professors of agriculture should improve the way they communicate to students. In particular, the Albanian professors should improve their verbal communication especially in terms of providing timely and quality feedback to students.

Theoretical implications: The study reveals differences in immediacy communication among countries (Austria, Slovenia and Albania) which the scientific literature considers to have a high-context culture.

Originality/Value: Given that no study has yet examined how students perceive professors’ communication in different European countries, this research helps understand the characteristics of agricultural professors’ communication.  相似文献
