Siler, Stephanie A.; Klahr, David; Price, Norman – Instructional Science: An International Journal of the Learning Sciences, 2013
Many studies have shown benefits associated with engaging students in problem-solving activities prior to administering lessons. These problem-solving activities are assumed to activate relevant knowledge and allow students to develop some initial knowledge structures, which support understanding of the lesson. In this paper we report the results…

Point and Click or Grab and Heft: Comparing the Influence of Physical and Virtual Instructional Materials on Elementary School Students' Ability To Design Experiments.
Peer reviewed Peer reviewed
Triona, Lara M.; Klahr, David – Cognition and Instruction, 2003
Fourth- and fifth-graders were taught how to design simple unconfounded experiments using one of two instructional methods differing only in whether children manipulated physical or virtual materials. Results indicated that the two types of materials were equally effective in achieving several instructional objectives, including the design of…

All Other Things Being Equal: Acquisition and Transfer of the Control of Variables Strategy.
Peer reviewed Peer reviewed
Chen, Zhe; Klahr, David – Child Development, 1999
Examined 7- to 10-year-olds' ability to acquire a domain-general processing strategy--Control of Variables Strategy (CVS)-- and make valid inferences. Found that with explicit training within domains and probe questions, children could learn and transfer the CVS. Probes without direct instruction did not improve CVS and inferential thinking…

The Interaction of Domain-Specific Knowledge and Domain-General Discovery Strategies: A Study with Sinking Objects.
Peer reviewed Peer reviewed
Penner, David E.; Klahr, David – Child Development, 1996
Nine- through 14-year-old girls made predictions about and performed experiments involving sinking objects. Found that children initially believed that weight alone determined an object's sinking rate, older but not younger children viewed experimentation as a way of exploring object attributes other than weight, and experimentation helped…
