Dr. K. A. KorbUniversity of Jos
Aptitude by Treatment Interactions(Cronbach & Snow) Aptitude: A personal characteristic that influences a
person’s ability to perform a specific task Treatment: Researcher’s intervention to determine
its effects on the dependent variable In this context, the treatment is an instructional intervention
Interaction: The effect of a treatment is influenced by one or more other variables
Dr. K. A. KorbUniversity of Jos
Aptitude by Treatment Interactions(Cronbach & Snow) ATI research is designed to determine whether the
effects of instructional methods are influenced by specific characteristics of the learners
Two Independent Variables Treatment and Aptitude
One Dependent Variable Academic Achievement

Aptitude by Treatment Interactions(Cronbach & Snow) Aptitude-Treatment Interaction (ATI): The
effectiveness of instructional strategies depends upon a person’s specific abilities
Aptitudes and instruction interact in complex patterns The effectiveness of an instruction for a particular
student depends on the task and situational variables

Well Established ATI’s
Classroom environmental structure and Cognitive ability Highly structured instructional environments:
High level of teacher control Well defined assignments
Low structured instructional environments: Freedom to pursue interests Open-ended assignments
Highly structured instruction seems to help students with low ability but hurt those with high abilities

Classroom environmental structure and Academic anxiety
Anxious students tend to learn better in highly structured classroom environments; non-anxious students tend to prefer low structure classroom environments

ATI Research Design
Treatment: Different methods of teaching the same content Random assignment of students to the treatments
Aptitude: Pre-testing of aptitude that is hypothesized to be more related to one treatment than the other
Academic Performance: Post-testing of academic performance as the dependent variable
Overall Conclusion: Optimal learning results when the instruction is exactly matched to the aptitudes of the learner

Gagné’s Nine Events of Instruction1. Get Attention
Information Processing Theory
2. State Objective Focus Attention
3. Stimulate recall of prior learning Transfer Schema Theory
4. Present the content Apply the most appropriate theory of learning
Dr. K. A. KorbUniversity of Jos
Gagné’s Nine Events of Instruction5. Provide guidance for learning
Scaffolding
6. Elicit performance Active learning
7. Provide feedback Research article
8. Assess performance Determine if students understand as necessary for prior
knowledge
9. Enhance retention and transfer Practice in multiple contexts
