Factor Analytic Study of Lecturer’s Teaching Assessment Scale in Obafemi Awolowo University, Nigeria
Bibliographic record
Abstract
This study presents a validation report of the Lecturer’s Teaching Assessment Scale (LTAS) developed for theassessment of lecturer’s teaching effectiveness in Obafemi Awolowo University, Ile-Ife, Nigeria. It also examinedthe factor structure of the LTAS, its construct validity, and internal consistency reliability coefficients. The studyadopted the survey research design. A total of 13,000 students that completed the LTAS online constituted thesample for the study. The 34-item LTAS was used to collect data for the study. Collected data were subjected toreliability and factor analyses. Results showed that the LTAS has two subscales - Attitude to Teaching and LecturePresentation and Organisation. The LTAS was adjudged to possess construct validity, and it was established throughexperts’ judgement. The results also revealed that the LTAS was reliable (Cronbach Alpha reliability coefficient of0.985, Spearman Brown’s Split-half reliability coefficient of 0.998 and Gutman’s Split-half coefficient of 0.997).Thus, the LTAS possessed adequate psychometric qualities that make it suitable for use among Nigerianundergraduate students.

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.
