Backward Design for Instruction
07 Apr 2010  Presentation Materials  Contributor(s): Krishna P. C. Madhavan, Sean Brophy
Backward design is an instructional design process that focuses on what specific learning objectives need to be accomplished and how learning will be assessed appropriately before the instructional materials are designed. This design process is the complete opposite of what instructors typically do where they select specific instructional activities or tools and then tailor their learning objectives around these activities. Hence the name, backward design. We emphasize appropriate planning …

Thinking about Learning Objectives
07 Apr 2010  Presentation Materials  Contributor(s): Krishna P. C. Madhavan
The first and most significant step in the backward design process is the identification of clear learning objectives that will eventually be assessed. Using New Bloom's Taxonomy as the theoretical basis, we highlight how learning objectives can be written such that they focus on cognitive and knowledge processes. We provide examples of good learning objectives and show how they are aligned with the New Bloom's model. Our goal is to allow students to progress from lower order cognitive and …

Framework for Evaluating Simulations: Analysis of Student Developed Interactive Computer Tools
21 Jul 2014  Papers  Contributor(s): Kelsey Joy Rodgers, Heidi A DiefesDux, Krishna Madhavan
Computer simulations are discussed in the learning environment from two major perspectives: 1) teaching students how to build simulations and 2) developing simulations to teach students targeted concepts. This study is approaching learning with simulations from a different perspective. We are interested in how students’ understandings of simulations develop through an iterative design challenge that requires them to create their own simulations. We investigated what firstyear...
