Interactive Teaching Techniques:

Are they transferable across cultures?

There is a substantial body of evidence to suggest that:

traditional lecturing is not an effective way of producing learning or understanding in students.

Physics education research (1980–2000)

has identified many common misconceptions

has led to the construction of standardized diagnostic tests

Mathematics and Physics Conceptual Evaluation

Thornton & Sokoloff, Am. J. Phys, 66(4), 1998, p 338

Physics education research (1980–2007)

has identified many common misconceptions

has led to the construction of standardized diagnostic tests

has prompted development of targeted teaching strategies.

For example: Interactive Lecture Demonstrations

use computers in lectures to log and display data in various representations,

rely on carefully controlled teacher-class interactions,

claim very substantial gains in student learning.

Evaluation of ILDs at Sydney University

Evaluation of ILDs at Sydney University

First semester 1999, 1 Regular class (130 students) taught with ILDs

Advanced stream and other 2 Regular streams (320 students) as controls

Module chosen was MECHANICS , (HRW chapters 1–12 )

Logistics

Control classes had 15 1-hour lectures (5 weeks)

Experimental class had 11 1-hour lectures plus 4 1-hour ILD sessions

All tested during first lecture period, and again in middle of the semester.

Pre-test scores: all Introductory classes

Conclusions?

This teaching technique seems to achieve what it claims (to a degree)

This teaching technique requires practice and commitment to be used successfully

There seems to be a small fraction of students who cannot be reached
