The Effect of Project-Based Learning Model on Persuasive Writing Skills of Saudi EFL Secondary School Students
Bibliographic record
Abstract
The aim of this study was to investigate the effect of project-based learning model on persuasive writing skills of Saudi EFL secondary students. The design of the study was quasi-experimental approach using pre and posttest for control and experimental groups. Participants were consisted of (59) students of third grade secondary school, randomly divided into two groups: experimental group consisted of (30) students and control group consisted of (29) students. Experimental group was taught using project-based learning while control group was taught using the traditional method. All participants were tested using the pre/post persuasive writing performance test before and after the intervention. The difference between the posttest's mean scores of the control and experimental groups were calculated using independent samples T-test. The result showed that there was a significant difference between the posttest's mean scores of the control and the experimental groups in favor of the experimental group. It was concluded that participants’ level of persuasive writing performance significantly developed after receiving the explicit project-based learning model.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
