Uncertainty is an important and fundamental concept in physics education. Students are often first exposed to uncertainty in introductory labs, expand their knowledge across lab courses, and then are introduced to quantum mechanical uncertainty in upper-division courses. This study is part of a larger project evaluating student thinking about…

Cognitive processes are procedures for using existing knowledge to combine it with new knowledge and make decisions based on that knowledge. This study aims to identify the cognitive structure of students during information processing based on the level of algebraic reasoning ability. This type of research is qualitative with exploratory methods.…

In this paper, I apply the Multiple Documents Text-Based Relevance Assessment and Content Extraction (MD-TRACE) model, to describe the types of cognitive processes that students engage to critically reason about social issues, as they are portrayed through mass media. In addition to examining such processes, I further consider the extent to which…

Students' capacity for making evaluative judgements of their own work is widely acknowledged as central to their learning within programmes as well as being vital to their subsequent professional practice. In higher education literature, the act of evaluative judgement is usually portrayed as a process of deliberative, analytical reasoning…

The main aim of the present investigation was to examine conditional reasoning skills in college students whose educational past had emphasized verbatim learning. A successive independent-samples design was utilized to explore the effects of instruction that explicitly targeted critical thinking principles in either freshman students or…

A critical component of scientific reasoning is the consideration of alternative explanations. Recognizing that decades of cognitive psychology research have demonstrated that relative cognitive accessibility, or "what comes to mind," strongly affects how people reason in a given context, we articulate a simple "cognitive…

We propose two contrasting types of student decision-making based on social and cognitive psychology models of separate mental processes for problem solving. Informal decision-making uses intuitive reasoning and is subject to cognitive biases, whereas formal decision-making uses effortful, logical reasoning. We explored indicators of students'…

This case study examines the salient features of two individuals' reasoning when confronted with a task concerning the cardinality and associated cardinal number of equinumerous infinite sets. The APOS Theory was used as a framework to interpret their efforts to resolve the "infinite balls paradox" and one of its variants. These cases…

The use of science classroom discourse analysis as a way to gain a better understanding of various student cognitive outcomes has a rich history in Science Education in general and Physics Education Research (PER) in particular. When students talk to each other in a collaborative peer instruction environment, such as in the CLASP classes…

This article explores the complementary strengths and weaknesses of grounded and abstract representations in the domain of early algebra. Abstract representations, such as algebraic symbols, are concise and easy to manipulate but are distanced from any physical referents. Grounded representations, such as verbal descriptions of situations, are…

Reports an experiment in which a topical system facilitated subjects' recall of information pertinent both to highly meaningful and less meaningful issues; based upon author's doctoral study, Pennsylvania State University. (RD)

A study conjectured that individuals make mental models of events when they reason from premises involving temporal relations. Several experiments using school children and university students as subjects found that problems that required one mental model elicited more correct responses than problems that required multiple mental models. (BC)

Investigates the asserted differences in reasoning between adults and second, fourth, and sixth graders in a manipulation of variables task using class inclusion and story problems with common everyday situations. Results are discussed in terms of sensible reasoning and problem-solving skills. (CM)

Challenges studies supporting Kohlberg's claim of invariance in the development of moral judgment which maintain that subjects' preferred responses to moral dilemmas are based on higher stages of thinking. Findings indicate language rather than levels of thinking is a significant factor in subjects' response preferences. (CM)

According to Humean framework, relations are judged to be causal to extent that they are characterized by regularity, continuity, and covariation among college students and college-bound 11- and 14-year-olds. Presents subjects with information about one of the following indices: potential causal factor covaried with effect and potential causal…
