Applications of blogging in problem based learning

摘要

The context of the study presented in this paper is a sixth-semester undergraduate course on "Relational database management system" that was held in session 2009-2010. The course is part of the bachelor's degree curriculum of Computer Science and Engineering branch at Punjab Technical University, Punjab, India. It consists of a lecture course and a concurrent lab course. The common approach has been to divide the course into lectures, tutorials, and practicals. To conduct practical sessions, lab plan is prepared beforehand by the faculty. The course duration is 1416 weeks. Here the lab course was conducted in a blended learning mode, starting with syllabus related tasks, then subject specific projects, and presenting team project results. Problem based learning (PBL) and Blogging have been introduced for practical sessions. This paper describes this novel approach in which problems are designed to cover the syllabus topics, and blogging is used to bridge the communication gap. A significant difference was seen between performance and attitude of the treatment group (PBL with blogging) and control group (only PBL) for Lab sessions. Additionally teamwork and communication skills were also significantly improved in the case of PBL with blogging class.
