10 Pilot results Core questionsCore questions Below is a breakdown of core questions per module,Below is a breakdown of core questions per module, Students from the redesign section scored significantly higher than traditional sections for all three modules:Students from the redesign section scored significantly higher than traditional sections for all three modules: M1: Redesign (X = 86.20%) > traditional (X=83.66%)M1: Redesign (X = 86.20%) > traditional (X=83.66%) M2: Redesign (X = 84.90%) > traditional (X=74.07%)M2: Redesign (X = 84.90%) > traditional (X=74.07%) M3: Redesign (X = 90.85%) > traditional (X=59.05%)M3: Redesign (X = 90.85%) > traditional (X=59.05%)

13 Issues & tweaks 1.Students compared DVMT 100 sections. 2.Redesign students did not effectively use their lab time wisely. 3.Redesign students did not have enough deadlines – 1x/module, night before exam. 4.Students fell behind next module while retaking previous module exam. 1.Fall 2011 – full implementation. 2.Changed lab to 2x/wk and used technology to block other sites. 3.Created several deadlines with last deadline before test review day. 4.Added retake week after Mod1. 1.Fall 2011 – full implementation. 2.Changed lab to 2x/wk and used technology to block other sites. 3.Created several deadlines with last deadline before test review day. 4.Added retake week after Mod1.

14 Issues & tweaks 1.The grading system in the redesign confused students. 2.Redesign students found and exploited a loophole about retaking modules next semester. 3.Lab assistants were scattered across different labs. 4.No pedagogy to address gender gap. 1.Revised to be based on weights that required and rewarded important course aspects. 2.Modified retaking of modules. 3.Assigned lab assistants. 4.Created Train Your Brain Program 1.Revised to be based on weights that required and rewarded important course aspects. 2.Modified retaking of modules. 3.Assigned lab assistants. 4.Created Train Your Brain Program

15 Issues & tweaks 1.Failure rate on first version of module exam was very poor: Mod1 = 27% passed Mod1 = 27% passed Mod2 = 20% passed Mod2 = 20% passed Mod3 = 17% passed Mod3 = 17% passed 1.Implemented PreModule Exam Earn 85% or higher – no need to take Module exam Reward studying & doing well 1.Implemented PreModule Exam Earn 85% or higher – no need to take Module exam Reward studying & doing well

18 Impact of changes Deadlines = large % students completed deadlinesDeadlines = large % students completed deadlines Weights & lab changes = better attendance and time on taskWeights & lab changes = better attendance and time on task Train Your Brain = no gender gap, better performance overallTrain Your Brain = no gender gap, better performance overall

19 Impact of changes 1.Failure rate on first version of module exam was very poor: Mod1 = 27% passed Mod1 = 27% passed Mod2 = 20% passed Mod2 = 20% passed Mod3 = 17% passed Mod3 = 17% passed 1.PreModule Exam results Module 1 Premod: 36% passed Version 1: 72% passed Module 2 Premod: 16.2% passed Version 1: 60% passed Module 3 Premod: 18.3% passed Version 1: 53% passed 1.PreModule Exam results Module 1 Premod: 36% passed Version 1: 72% passed Module 2 Premod: 16.2% passed Version 1: 60% passed Module 3 Premod: 18.3% passed Version 1: 53% passed
