Description¶

Student-Teams Achievement Divisions (STAD; Slavin, 1994) is a cooperative-learning technique built around teams of 4-5 students. The teacher presents a lesson or unit to the whole class and later tests students on it individually, but grades are based partly on each student's own improvement and the team's collective improvement, not solely on absolute test performance. Team members work together during the lesson to help each other improve as much as possible, then take the actual test as individuals — combining team-based preparation with individual accountability at assessment time.

Design Implications¶

Context¶

Requirements¶

• A whole-class lesson or unit content that all teams study together before individual testing
• An improvement-based scoring scheme (baseline vs. current performance) rather than only absolute score, so that both stronger and weaker students can contribute meaningfully to their team's result

Constraints¶

• Without an improvement-based scoring component, STAD collapses into ordinary group study with no distinct accountability structure

Target Learners¶

• Mixed-ability teams, since improvement-based scoring gives lower-performing students a genuine stake in contributing to team success rather than being outscored regardless of effort

Target Learning Goals¶

• Content mastery verified individually, combined with a team incentive to help every member improve

Instructions¶

1. Present the lesson or unit to the whole class.
2. Assign students to teams of 4-5.
3. Have teams study and prepare together, with team members helping each other toward individual improvement.
4. Test all students individually on the material.
5. Score individuals partly on their own improvement relative to their own baseline, and partly on the team's collective improvement — not solely on absolute performance level.

Related Strategies¶

• Jigsaw Method — another 4-6-student cooperative structure, but organized around expert specialization on subtopics rather than shared study of the same whole-class content
