Touchy feely vectors: A compensatory design approach to support model‐based reasoning in developing country classrooms

Abstract

AbstractEducational technology designs in developing countries mostly focus on making knowledge resources widely available, through MOOCs, repositories and computer‐based tutoring. The use of digital media for cognitive augmentation, particularly interactive designs that help learners understand modelling topics in STEM, is underexplored. We report a 3‐year design study examining this potential in the Indian context, testing two iterations of an interactive system, Touchy‐Feely Vectors (TFV). The design supports learning vectors, a modelling topic pre‐university students struggle with. Virtual lesson‐plans were co‐designed with teachers to augment — but not replace — their existing practices, and to address classroom and resource constraints. Pre‐post testing of TFV‐1 (a computer‐based prototype) showed that it helped students develop a more integrated vector concept, and improved their reasoning. Field‐implementation of TFV‐2 (a textbook‐linked touch‐screen based design) in 6‐classrooms (3‐Control, N=135; 3‐Experimental, N=131) showed that it fostered cognitive engagement in average‐students and geometry‐algebra integration (model‐based reasoning) in good‐students. These results, along with a requirements analysis based on textbooks, indicate that the interaction possibilities supported by different representational media critically shape student reasoning. The study also illustrates a systematic approach to design and test digital media systems that support cognitive augmentation in developing countries.
