The goal of this study was to examine the use of a technological and engineering design based learning (T/E DBL) challenge as a strategy for facilitating student comprehension of nonfiction/informational text inclusive of graphical devices. The data for this mixed methods exploratory case study were collected using a variety of instruments which assessed the prior knowledge, general graphical device comprehension, and reading comprehension of both familiar and unfamiliar texts in order to form a detailed picture of the six participants throughout the study. The six participants were examined as whole group and as reading level dyads (below, on, and above grade level) as they progressed through three T/E DBL challenges that were developed to support graphical device comprehension instruction. T/E DBL was found to increase reader text interactions and graphical device usage, support the development of general graphical device comprehension for diagrams and tables, improve comprehension of unfamiliar science texts, and provide particular benefit to below grade level readers. The results of this study demonstrate the need for further research into the benefits of T/E DBL for reading instruction, particularly of graphical devices. This research should include a further exploration of the potential benefits for graphical device comprehension and comprehension of unfamiliar science and engineering texts that include graphical devices, as well as the curricular, training, and implementation needs. / Doctor of Philosophy / This study examined how challenging fifth grade students to design a technology to meet an engineering need can support student understanding of nonfiction/informational texts which include informational graphics (graphical devices). The participants of this study were asked to create designs of different types of technology which would benefit from the information in the provided informational texts and graphics. A variety of data were gathered on six fifth grade participants as they worked through a serious of design challenges that were paired with reading passages that included graphics (graphical devices). Graphical device instruction using design challenges was found to increase readers' interactions with texts and their usage of graphical devices, support the development of comprehension for diagrams and tables, improve comprehension of unfamiliar science texts, and provide particular benefit to below grade level readers. The results of this study demonstrate the need for further research into the benefits of using design challenges for reading instruction, particularly of graphical devices.
