Currency · newest study 1988 · not yet checked against its sources · not reviewed by a person · overdue for a recheck since 1993: baselines and conditions change
Evidence quality · No study behind this claim is a peer-reviewed article with a DOI: it rests on an ERIC document (a report, conference paper or thesis). It is kept because 4 design pages cite it; treat it as a lead to check, not an established finding.

Subclaims¶

q2 i? In a three-screen video study, experts monitored all screens and gave more, more detailed comments, while novices and postulants made contradictory statements and struggled to monitor the displays. → Berliner 1988

q2 · i? · theoretical · r3

Observational study (Sabers, Cushing, & Berliner, 1988) in which expert, novice, and postulant teachers watched three simultaneous video screens of one lesson and talked aloud. Experts 'responded effortlessly and fluidly' while novices reported contradictory observations; experts averaged 27.4 comments versus 20.5 for novices and 23.2 for postulants.

"They not only made more comments about what was happening (experts averaged 27.4 comments during this segment of the task; novices, 20.5 comments; postulants. 23.2 comments), but their comments were more detailed and descriptive than those of the other two groups."

Discussion¶

Learner Variables¶

• Prior Knowledge — predictor: learners who differ on it differ in outcomes

Related Claims¶

• In the initial skill acquisition phase, authentic video yielded higher overall observation assignment scores than virtual simulation — the general claim this finding bears on, with the studies behind it
• Experts discern instructional significance in classroom scenes while novices and postulants treat all visual stimuli as equally important — related
• Experts attend selectively to atypical events, merging typical student information into a group picture, while novices and postulants study all student details — related
• Experts predict classroom phenomena and student errors far more than novices, who rarely anticipate misalgorithms — related
• Expert teachers show intense emotionality and sense of responsibility for their performance, unlike affectless novices and postulants — related
• Students and researchers gave systematically different types of explanatory comments about the visual argument, with students rejecting pictures as proofs — related
• Classroom observations revealed subtle but decisive teaching differences correlated with the difference in learning outcomes — related
• Expert teachers' classroom perception appears knowledge-driven while novices' appears image-driven, guided by salient visual features — related
• Novices skipped more classroom areas than experts in all four videos, missing areas that experts continually monitored — related
• Experts detect and correct small changes before events become full-blown, while novices are distracted by possibly irrelevant phenomena — related
• Teaching experience is associated with higher frequency of mental/perceptual and action/event words in think-aloud about classroom scenes — related
• Experts revisited (monitored) more classroom areas showing student interaction, while novices revisited areas lacking classroom activity — related
• Novices and experts committed similar total error numbers but different error types in computer work — related
• Expert teachers interpret classroom events more analytically and focus on learning consequences, while novices emphasize student behavior — related
