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.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
