... before it’s too late

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
