Computer science students’ use of the internet for academic purposes: difficulties and learning processes     

Yifat Ben-David Kolikant 《Computer Science Education》2013,23(3):211-231

ABSTRACT

Higher-education students now have more alternatives for searching for information than previous generations had. The Internet is a vast ocean of information sources, albeit with diverse reliability and quality. In Web 2.0 platforms, any participant can be a content creator. This reality is challenging for both the instructors and the students. We conducted interviews with 12 Computer Science students and 8 instructors from two universities to (a) identify the difficulties students encounter, if at all, (b) identify the learning processes that students undergo, if at all, when using the Internet for their CS studies, in particular, programming tasks; and (c) elicit instructors’ perceptions of students’ use of the Internet. Both students and instructors agreed that although using the Internet is not trivial, direct teaching of this skill is unnecessary. Instructors differed in their attitudes towards students’ use of the internet. We found that in the first year the students’ use of the Internet and their difficulties are similar to reports in the empirical literature, and echo the instructors’ concerns. However, after extensive experience, students undergo a learning process, and their ability to navigate the myriad sources, as well as to search, manage, and effectively evaluate Internet sources improves. Students mentioned their improved abilities to code as a means to effectively evaluate information sources.  相似文献

Exploring the Cautionary Attitude Toward Wikipedia in Higher Education: Implications for Higher Education Institutions     

Gemma Bayliss 《New Review of Academic Librarianship》2013,19(1):36-57

This article presents the research findings of a small-scale study which aimed to explore the cautionary attitude toward the use of Wikipedia in the process of learning. A qualitative case study approach was taken, using literature review, institutional documentation, and semi-structured interviews with five members of academic teaching staff from a UK Business School. Analysis found the reasons for the cautionary attitude were due to a lack of understanding of Wikipedia, a negative attitude toward collaborative knowledge produced outside academia, and the perceived detrimental effects of the use of Web 2.0 applications not included in the university suite.  相似文献   

Impact of Internet Images: Impression-Formation Effects of University Web Site Images     

《Journal of Marketing for HIGHER EDUCATION》2013,23(2):49-68

ABSTRACT

Institutions of higher education are increasingly becoming dependent on Web-based marketing to reach out to their target audiences. The current empirical study examines the types of impressions formed by prospective students based on exposure to different university Web site images. A between-subjects experiment was conducted using four identical university Web sites that differed only in their visual representation of campus architecture (modern/traditional) and landscaping (presence or absence of contextual greenery). The results show how the types of visuals viewed influence impressions about academic prestige, athletic reputation, cultural vitality and invitingness of a university.  相似文献

Use of Web 2.0 technologies in K-12 and higher education: The search for evidence-based practice     

《Educational Research Review》2013

Evidence-based practice in education entails making pedagogical decisions that are informed by relevant empirical research evidence. The main purpose of this paper is to discuss evidence-based pedagogical approaches related to the use of Web 2.0 technologies in both K-12 and higher education settings. The use of such evidence-based practice would be useful to educators interested in fostering student learning through Web 2.0 tools. A comprehensive literature search across the Academic Search Premier, Education Research Complete, ERIC, and PsycINFO databases was conducted. Empirical studies were included for review if they specifically examined the impact of Web 2.0 technologies on student learning. Articles that merely described anecdotal studies such as student perception or feeling toward learning using Web 2.0, or studies that relied on student self-report data such as student questionnaire survey and interview were excluded. Overall, the results of our review suggested that actual evidence regarding the impact of Web 2.0 technologies on student learning is as yet fairly weak. Nevertheless, the use of Web 2.0 technologies appears to have a general positive impact on student learning. None of the studies reported a detrimental or inferior effect on learning. The positive effects are not necessarily attributed to the technologies per se but to how the technologies are used, and how one conceptualizes learning. It may be tentatively concluded that a dialogic, constructionist, or co-constructive pedagogy supported by activities such as Socratic questioning, peer review and self-reflection appeared to increase student achievement in blog-, wiki-, and 3-D immersive virtual world environments, while a transmissive pedagogy supported by review activities appeared to enhance student learning using podcast.  相似文献
