Hypothetico Deductive Reasoning (HDR) series of reasoning steps followed in order to explain any phenomena (Lawson, 2000)

Learning path of Geneticus Investigatio

Student chooses hypothesis to test

Student designs experiment and make prediction

Student runs experiment to test prediction

Student compares predicted and observed result

Student reads experimental observations

Potential Research Questions • Do students who learn from Geneticus Investigatio develop HDR reasoning abilities? • What are students’ perceptions of Geneticus Investigatio for learning HDR ? Assessment Writing of design of experiment, prediction, observation and comparison of results explicitly

Glimpse of the features of Geneticus Investigatio

Designing a technology enhanced learning environment for hypothetico-deductive reasoning in genetics

Research Methodology

Steps are • Formation of hypotheses • Checking of hypothesis by experimentation • Designing of experiment • Predicting outcome based on experiment • Collecting observed outcome • Comparing predicted and observed outcome
