Today's scientific texts are complex and multimodal. Due to new technology, the number of images is increasing, as is their diversity and complexity. Interaction with complex texts and visualizations becomes a challenge. How can we help readers and learners achieve multimodal literacy? We use data from the audio description of a popular scientific…

The purpose of this exploratory study was to investigate the cognitive processes used by individuals who read a refutational text about physics and demonstrated conceptual change learning. Four high school readers whose initial conceptions differed from the scientific conception of Newton's first law thought aloud while reading a refutational…

Research on problem solving typically does not address tasks that involve following detailed and/or illustrated step-by-step instructions. Such tasks are not seen as cognitively challenging problems to be solved. In this paper, we challenge this assumption by analyzing verbal protocols collected during an Origami folding task. Participants…

We review and extend existing frameworks on modeling to develop a new framework that describes model-based reasoning in introductory and upper-division physics laboratories. Constructing and using models are core scientific practices that have gained significant attention within K-12 and higher education. Although modeling is a broadly applicable…

The Dirac delta function is a standard mathematical tool that appears repeatedly in the undergraduate physics curriculum in multiple topical areas including electrostatics, and quantum mechanics. While Dirac delta functions are often introduced in order to simplify a problem mathematically, students still struggle to manipulate and interpret them.…

The internal design thinking behaviour of designers in the concept development has been an important issue of cognitive psychology. In this study, the design thinking process designers have in applying digital media and traditional paper in the early concept development stage was explored. Special focus was made on the structure and procedure of…

This thesis explores the role of multiple representations in introductory physics students' problem solving performance through several investigations. Representations can help students focus on the conceptual aspects of physics and play a major role in effective problem solving. Diagrammatic representations can play a particularly important role…

Background: Research is needed to explore conceptual change in relation to achievement goal orientations and depth of processing. Aims: To address this need, we examined relations between achievement goals, use of deep versus shallow processing strategies, and conceptual change learning using a think-aloud protocol. Sample and Method:…

This exploratory study highlights certain differences in the way an expert and a novice engineer used their analyzing and generating skills while solving a fairly ill-structured design problem. The expert tends to use more inferences and elaboration when solving the design problem and the novice tend to use analysis that is focused on the…

Personal epistemology has typically been conceptualized in one of two primary ways: as a cognitive developmental process or as a system of beliefs. The approach that is elaborated here is to conceive of epistemological understanding as a metacognitive process that activates epistemic theories, a multidimensional set of interrelated beliefs about…

The role of planning in the design of digital circuits was studied in two experiments. One compared the planning-related activities of expert designers and beginning students of design, and the other looked at the effect on circuit-design processes of forcing students to construct a global plan. In experiment 1, five undergraduate students…

This study examined students' active roles in constructing knowledge when learning new information in the domain of biological evolution. A computer-based connectionist methodology was developed to provide a way to present students with new information while the experimenter provides probe statements congruent with or contradictory to the…

Analyses of the cognitive activity displayed by students on existing innovative assessments in science were conducted. The project has worked with pilot alternative assessment programs in Connecticut and California to document the match or mismatch between the skills and processes that the assessment is designed to tap and those actually elicited.…
