Gates’ Foundation 2015Report (January 2015)This framework identifies twodistinct segments that accountfor over 40% of the faculty andare well poised to be adopters oftechniques, tools, and behaviorswhich will benefit students. Ofthis entire group, half are alreadyadopting some emergingpractices, and may serve asexemplars to others. (p. 5)[FTI Consulting. (2015). U.S. Postsecondary Faculty in 2015: Diversity inpeople, goals and methods, but focused on students: FTI Consulting.]10

QuestionTitlea PulleyBlocks andTwo blocks are connected via a pulley. The blocks are initially at rest asblock m1 is attached to a wall. If string A breaks, what will the accelerationsof the blocks be? (Assume friction is very small and strings don’t stretch)Am1A. a1 0; a2 0BB. a1 g ; a2 gC. a1 0; a2 gm2D. a1 g ; a2 0E. None of the aboveWhy are the assumptions above important?
CommentsSolutionAnswer: EJustification: None of the above answers is correct. Consider twoblocks as one system: one can see that the system has a mass of(m1 m2), while the net force pulling the system down is m1g.Therefore, applying Newton’s second law, one can see that theacceleration of the system must be less than g: am2 g ( m1 m2 )m2g g( m1 m2 )Some people think that the acceleration will be g. They forget thatthe system consists of two blocks (not just m1) and the only pullingforce is m1g. Thus the system is NOT in a free fall. Compare thisquestions to the previous one to see the difference.

Example: Demos vs.Interactive Lecture Experim’sOnly 25% of the studentschose the correct response.59% chose the incorrectresponse (D).[ M. Milner-Bolotin et al, Journal of College Science Teaching,March 24, 2015CAP Congress Saskatoon 2007January-February2007, pp.45-49.]26
Pedagogy: InteractiveLecture ExperimentStudents work in smallgroups, collect necessarydata, come up with theanalysis and solutionand then check if theiranswer is meaningfulusing in-class liveexperiment (datacollection).Traditional lecture demonstrations are replaced by Interactive Lecture ExperimentsMarch 24, 201527

Conclusions: Deliberate PedagogicalThinking with TechnologyTechnology opens unprecedented opportunities foreducators, but we have just scratched the surface.We have to explore how to use it to promotemeaningful science education. Teacher educationboth at K-12 and post-secondary levels should modeleffective research-based uses of technology.

National Math and Science Initiative (NMSI). In just five years, NMSI has planted math and science programs in schools and universities that are raising academic rigor and achievement across the United States as a result. As this Annual Report shows, NMSI is transforming science, technology, engineering, and math (STEM) education in America.
