“But it required a few years before I perceived what a science teacher's job really is.
The goal should be, not to implant in the student's mind every fact that the teacher knows now; but rather to implant a way of thinking that will enable the student, in the future, to learn in one year what the teacher learned in two years.
Only in that way can we continue to advance from one generation to the next.”

Overview
How things are changing; technology as an example driver
Implications for instructors; the anatomy for future success
The case for students as co-creators, and four examples of how to enact that

skills, values and habits
Students as collaborators, co-creators
Four examples (of increasing complexity to implement)
1. “Things I wish I’d known”
2. The most important course you can take
3. Undergraduate learning assistants in the classroom
4. Student-generated assessment and content

Selected results and analysisEngagement - how do students use the system?
Benefits - what is the impact on learning?
Question quality - how good is what students produce?

Quality of student authored content
Bloom’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.

Question quality summary (UoE 2011)
2 successive years of the same course (N=150, 350)
‘High quality’ questions: 78%, 79%
Over 90% (most likely) correct, and majority 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.
That’s not commonBottomley & Denny Biochem and Mol Biol Educ. 39(5) 352-361 (2011)
107 Year 2 biochem students 56 / 35 / 9 % of questions in lowest 3 levels.
Momsen et al CBE-Life Sci Educ 9, 436-440 (2010)
“9,713 assessment items submitted by 50 instructors in the United States reported that 93% of the questions asked on examinations in introductory biology courses were at the lowest two levels of the revised Bloom’s taxonomy”

Implementation logistics Cohort split into 4 groups
Each week one group tasked with creating LOs
Each submission counts for 2.5% of final grade
Repeat cycle twice per Semester
Students can submit >2 LOs & receive grade for best 2
Short survey on submission
Students encouraged to apply CC licenses

Not quite the whole story• Despite these outstanding examples, many students
didn’t like the assessment
• difficulty level vs other assessed components of the course
• credit weighting
• Students dropped these assessments more than other coursework
• Strange ‘phase transition’ for LO vs exam grades
One final thought….why this all works
