Abstract

fetched live from OpenAlex

The present study was executed with the purpose of validating ELT Certificate Lesson Observation and Report Task (ELTC-LORT), which was developed by China Language Assessment to certify China’s EFL teachers by performance-based testing. The ELT Certificate has high-stakes considering its impacts on candidates’ recruitment, ELT in China and quality of education, so it is crucially important for its validation so as to guarantee fairness and justice. The validity of task construct and rating rubric went through a process suited for many-facet Rasch measurement supplemented with qualitative interviews. Participants (N = 40) were provided with a video excerpt from a real EFL lesson, and required to deliver a report on the teacher’s performance. Two raters graded the records of the candidates’ reports using rating scales developed to measure EFL teacher candidates’ oral English proficiency and ability to analyze and evaluate teaching. Many-facet Rasch analysis demonstrated a successful estimation, with a noticeable spread among the participants and their traits, proving the task functioned well in measuring candidates’ performance and reflecting the difference of their ability. The raters were found to have good internal self-consistency, but not the same leniency. The rating scales worked well, with the average measures advancing largely in line with Rasch expectations. Semi-structured interviews as well as focus group interviews were executed to provide knowledge regarding the raters’ performance levels and the functionalities of the rating scale items. The findings provide implications for further research and practice of the Certificate.

Not 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.
