The SettingBig10-R1 state university

Diverse student population

Intro science courses

Between 200 and 3,000 students/course

Instructors rotating between semesters

No or few TAs

The Problem(s)Large lecture halls, no personal interaction with majority of students

Often no resources to grade homework

If homework is offered:

little personalized feedback

students blindly copying each other’s answers

few conceptual discussions between students when collaborating, no peer-teaching outside class

The Surprise

Most instructors DO care

Page 6: Knowing what 400 students know

LON-CAPA6

The ChallengeProvide meaningful formative assessment to students

Provide timely feedback to both students and instructors

Reduce blind copying of answers to

foster conceptual-level collaboration

give a true picture of learner progress

Provide a scalable solution within the realities and budgets and available resources

The solution (maybe, for now): LON-CAPA

Learning Content Management System

Course Management System

Assessment System

Open-Source and Free

Page 8: Knowing what 400 students know

LON-CAPA8

Online assessment with immediate

adaptive feedback and multiple tries

Different students get different

versions of the same problem

different options

different graphs or images

different numbers or formulas

Effectiveness

LON-CAPA is a tool, not a curriculum.Effectiveness depends on how it is used.
