Using UX and LXD to Analyze Constructivism in Technical Communication Textbook Design

<bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Background:</b> Constructivism is a prevalent theory in technical and professional communication (TPC) pedagogy that extends to various aspects of learning, including textbook design. This study considers the way that learners interact with textbooks and how incorporating constructivist design elements is important for both instructors and students. <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Literature review:</b> Previous research has highlighted the importance of textbook design in facilitating learning and the ways that textbooks reflect ideology. However, there is limited literature on the role of constructivist principles in textbook design and their impact on learners and faculty. <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Research questions:</b> 1. What design elements in textbooks align with a constructivist pedagogy? 2. To what extent do textbooks in TPC follow a constructivist design? 3. Do students and faculty prefer constructivist designs? <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Research methodology:</b> The study employed a heuristic review using a novel heuristic, the Constructivist Textbook Rubric, to evaluate a sample of eight technical communication textbooks. Following this, comparative usability testing was conducted with both professors and students to assess preferences and learning outcomes. <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Results:</b> The study resulted in the development of a comprehensive tool for evaluating textbooks based on alignment with constructivist design principles and learning theory. Both the heuristic review and user testing demonstrated advantages associated with textbooks that incorporated constructivist elements in their design. <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Conclusion:</b> The findings suggest that textbooks designed with constructivist principles can improve learning outcomes for both learners and faculty. By using the Constructivist Textbook Rubric, college instructors can make informed decisions when selecting textbooks, ultimately benefiting learners through enhanced information synthesis and retention.
