Global transition in higher education: From the traditional model of learning to a new socially mediated model
Bibliographic record
Abstract
This article reports on the pedagogical value of Web 2.0 tools at Unisa (i.e., whether these tools can improve teaching and learning). A quantitative approach was used to conduct the study, with a questionnaire as a data collection instrument. The sample size was 301 lecturers drawn using stratified sampling, with proportional allocation drawn from all Unisa colleges. Descriptive statistics were employed to analyse and interpret the data. The results show that Web 2.0 tools are playing a pivotal role when it comes to opening avenues and collapsing the transactional distance in an ODL institution. A combination of web technology and the trend of constructivism can transform the learning process. This article therefore recommends that Unisa sensitise its lecturers to the adoption of Web 2.0 tools as an innovative way to improve teaching and learning.

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.
