Technology - implications

Changing the

So what are the

we need to embrace, develop and refine?

skills, values and habits

Selected results & analysis

Engagement - how do students use the system?

Benefits - what is the impact on learning?

Question quality - how good is what students produce?

Engagement with PeerWise

Engagement with PeerWise

Engagement with PeerWise

Engagement with PeerWiseGenerally, students did

• Participate beyond minimum requirements • Engage in community learning, correcting errors • Create problems, not exercises • Provide positive feedback

Generally, students did not

• Contribute trivial or irrelevant questions • Obviously plagiarize • Participate much beyond assessment periods • Leave it to the last minute (sort of….)

Question/Explanation QualityBloom’s Taxonomy of levels in the cognitive domain

Score Level Description

1 Remember Factual knowledge, trivial plugging in of numbers

2 Understand Basic understanding of content

3 Apply Implement, calculate / determine. Typically one-stage problem

4 Analyze Typical multi-step problem; requires identification of strategy

Evaluate Compare & assess various option possibilities; often conceptual

Synthesize Ideas and topics from disparate course sections combined. Significantly challenging problem.

1 Inadequate Wrong reasoning and/or answer; trivial or flippant

2 MinimalCorrect answer but with insufficient explanation/justification/ Some aspects may be unclear/incorrect/confused.

3 Good Clear and detailed exposition of correct method & answer.

4 ExcellentThorough description of relevant physics and solution strategy. Plausibility of all answers considered. Beyond normal expectation for a correct solution

Results (UoE 2010-11)2 successive years of the same course (N=150, 350)

‘High quality’ questions: 78%, 79%

Over 90% (most likely) correct, and 3/5 of those wrong were

identified by students.

69% (2010) and 55% (2011) rated 3 or 4 for explanations

Only 2% (2010) and 4% (2011) rated 1/ 6 for taxonomic level.
