LON-CAPA3
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
LON-CAPA4
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
LON-CAPA5
The Surprise
Most instructors DO care
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
LON-CAPA7
The solution (maybe, for now): LON-CAPA
Learning Content Management System
Course Management System
Assessment System
Open-Source and Free
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.
