Abstract
This discussion was recorded on June 15, 2021, with the American Center for the Study of Distance Education and transcribed for the American Journal of Distance Education to capture the essence and depth of the field of distance education from two seminal leaders. Dr. Farhad Saba, professor Emeritus of Educational Technology at San Diego State University (SDSU), has been in the field since 1973 and has authored more than 100 articles and chapters in books. Dr. Rick Shearer has over 35 years of experience in distance education and has served in higher education leadership and learning design roles. Both are Mildred B. and Charles A. Wedemeyer Award recipients and recently coauthored the book Transactional Distance and Adaptive Learning: Planning for the Future of Higher Education.

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.
