An evaluation of web enhanced instruction in college level biology courses

Abstract

Websites that accompany science courses typically aim to provide easy access to learning materials, and to facilitate student-instructor communication. We tested whether these aims were achieved in two web enhanced, lower division undergraduate biology courses in an Israeli college. We collected data on the students' attitudes through pre-and postcourse questionnaires, monitored their usage of the course websites, and related these data to the students' final course grades.The students (n=96) accessed the websites frequently and regularly, and regarded them as important sources of information. About 47% of the students reported an increased level of general interest in the courses due to the websites. Students mainly downloaded lecture slides and exercise forms from the websites, but did not use the sites to communicate among themselves, or with the instructor. Final course grades were not correlated with the frequency of usage of the website. Female students had a more positive pre-course attitude towards the websites as compared with male students. However, there was no difference between men and women in usage of the course websites, and in achievement levels.We conclude that the website component of the courses in our study facilitated delivery of learning materials and individual study, but not the social aspects of learning. We suggest that effective design of web enhanced courses can overcome this limitation by stressing social interactions and group learning during face to face sessions.

Online search for information about universities: a Hong Kong study

“…Gender has been studied widely across various disciplines and has become more prominent in understanding variation in internet usage and behaviour (Keasar et al , 2005; Tsai et al , 2012; Çevik, 2015). With the rapid growth and advance of digital technology, some studies have focused on the gender differences in perceived online skills (Hargittai and Shafer, 2006) online education (Volery and Lord, 2000) and e-learning activities (Cuadrado-García et al , 2010).…”

University students' online information searching strategies in different search contexts

“…Gender is always an important research issue for Internet usage (Chou & Tsai, 2007;Keasar, Baruch & Grobgeld-Dahan, 2005;Li, 2005). Regarding gender differences in online search strategies, Large, Beheshti and Rahman (2002) found that boys were more active searchers than girls in formulating more queries, clicking on more hyperlinks per minute, and following up on more hits, spending less time viewing individual pages and jumping pages more frequently.…”

Pedagogy and technology – which has the upper hand? Lessons from technological implementation at the College of Judea and Samaria, Israel

“…Most of these studies were conducted on a small scale (e.g. Barnes et al , 1999: Huff, 1997; Kaesar et al , 2005; Leung and Ivy, 2003; Morss, 2001; Washenberger, 2001). In one of the few relatively large studies, Talay‐Ongan and Gosper (2000) investigated student feedback in relation to two undergraduate courses which were delivered in face‐to‐face mode with web‐supported delivery.…”
