Land, Zimmerman (2015) Socio-technical dimensions of an outdoor mobile learning environment
Theoretical framework for the present study
Augmenting thinking using technology
Augmenting thinking through guided participation
The role of the environment
Learner's prior knowledge, experiences, values, and attitudes
Research Purpose
Methodology
Participants and setting
Socio-technical design strategies across the three studies
Design conjecture 1: support learners to make scientific observations outdoors.
Design conjecture 2: use child-centered designs for mobile, informal learning
Design conjecture 3: use conceptual models across activities versus discrete factual knowledge tied to singular objects
Design conjecture 4: scaffold complex disciplinary practices in natural settings
Video-based data sources and analyses
Results for the design iterations
Iteration 1: Tree Investigators socio-technical design for tree/species identification
Conversational analysis of science talk
Case study analysis of a family tour
Implications for design of iteration 2
Iteration 2: conceptual organizer supporting observations and explanations
Conversational analysis of science talk
Pretest-posttest knowledge gains
Video analyses of identification practices in the forest
Implications for design of iteration 3
Iteration 3: conceptual organizer with annotations to support identification practices
Influence of the socio-technical system on science talk
Discussion
