Description

The learning environment contained a task database of monohybrid cross problems in biology: "The task database (cf. Kostons et al. 2012) contained 75 problems at five levels of complexity, with three levels of support within each complexity level". Complexity increased via multiple answers, reasoning type, generations, and unknowns; support faded from 4/5 worked-out steps to none, in line with the completion strategy and the 4C/ID model. Students freely selected eight tasks during the self-regulated learning phase.

Design Implications

Context

Requirements

  • Learners must be able to choose tasks themselves so that trained self-assessment and task-selection skills can be exercised

Constraints

Target Learners

  • secondary education students (second year higher general secondary education, age ~13-14)

Learning Goals

  • problem-solving skills in genetics (monohybrid crossing)
  • self-assessment and task-selection skills in self-regulated learning
