Project-based Learning via Blackboard Discussion Board for Vocabulary Acquisition of Saudi EFL Learners

Abstract

The global pandemic of COVID-19 affected all learning systems worldwide. It shifted the attention to alternative online learning platforms, including discussion boards, blogs, and other tools that necessitate collaborative teamwork. The current research employed project-based learning (PBL) via the blackboard discussion board to improve vocabulary acquisition for Saudi EFL learners and to determine the advantages and difficulties associated with learning. The researchers used a quantitative research design with equivalent groups of 60 female students from King Khalid University divided into two study groups: 30 for the experimental group taught through project-based learning via discussion board and 30 for the control group taught traditionally. Pre- and post-vocabulary tests were administered to the two groups, and a questionnaire of four dimensions about the advantages, skills, effects, and challenges encountered by students through learning were post-administered to the experimental group. Results proved that project-based learning employed through the discussion board enhanced students' receptive and productive vocabulary knowledge. The questionnaire analysis revealed that the PBL increased teamwork skills and responsibility.  It motivated students' problem-solving skills and autonomous learning. Despite these merits, there were some challenges, such as the instability of the internet connection, lack of time, and some students' hesitation to deliver presentations.
