The Evidence on Teaching

The FCS1

Tew, A. E., & Guzdial, M. · 2011

grade Dreviewindependentreplicated
Sample
Not confirmed
Population
CS1 students across multiple languages and institutions.
Design
An instrument-development and validation study, not an effect study. The full registered title is "The FCS1: a language independent assessment of CS1 knowledge"; Crossref registers the main title separately. Included because it is the origin of the only serious attempt at a validated, language-independent measure of CS1 knowledge — the thing whose scarcity is this subject's central methodological problem. Read at secondary depth.
Key findings
The first validated, language-independent assessment of foundational CS1 knowledge, built explicitly as computing's answer to physics' Force Concept Inventory. Its existence — and the fact that a decade later its authors were still writing about how rarely it and its successor get used — is the measurement story of this subject.
Genetic confound
Not applicable — instrument validation.
Replication notes
Replicated and re-validated as the SCS1 by Parker, Guzdial & Engleman (2016), which found weaker reliability than the original.
