This study examines the potential to use non-expert, crowd-sourced raters to score essays by comparing expert raters' and crowd-sourced raters' assessments of writing quality. Expert raters and crowd-sourced raters scored 400 essays using a standardised holistic rubric and comparative judgement (pairwise ratings) scoring techniques, respectively.…

Theorists and educators increasingly highlight the importance of computational thinking in STEM education. While various scaffolding strategies describe how to best support this skillset (i.e., paired programming, worked examples), less research has focused on the design and development of these digital tools. One way to support computational…

Background: Pre-college engineering education reform documents aim to help students develop engineering literacy. Helping students develop sophisticated epistemological views about engineering makes a significant contribution toward developing engineering-literate citizenry. Despite these widely recognized benefits, research on students' and…

Professional skills have long been perceived as lacking in junior engineers. Adopting a social realist theoretical framework of knowledge in practice, a hypothesis-based survey study of early career engineers' perceptions of engineering expertise was conducted. It investigated a professional skills readiness difference between initial career…

Debugging is the most difficult part of programming for novices. Through comparative experiments, this paper compares the differences between novices and the experts in the debugging process from the perspective of the frequency of each debugging skill behavior and the connection of each behavior. The study find that there is a difference in the…

The problem addressed by this study was that new school administrators are not prepared to lead special education programs. The purpose of this qualitative case study was to explore new school administrators' perceptions of their preparation and knowledge in leading special education programs in a kindergarten through 12th grade school setting.…

This generic qualitative study examined how mid-to-late career experts in the U.S. space exploration sector transfer tacit knowledge to novices, with a particular focus on fostering employee engagement. Semi-structured interviews were conducted with ten industry experts from various sectors within space exploration. Thematic analysis identified…

This article's goal is to encourage the use of modeling as a pedagogical approach, particularly in business law and ethics education. It attempts to do so in three parts. First, it sets forth the expert-novice knowledge gap problem. It draws on academic research regarding expertise from a diverse set of fields to demonstrate how experts and…

Much work has been done to characterize the reasoning of students as they solve mathematics-intensive problems and characterizing differences in expert and novice problem solving. In this work, we characterize the problem-solving strategies in a classroom setting of "transitioning novices," students who have completed an introductory…

Graphics in the form of video have been shown to be useful in presenting information to students. When designing graphic videos to optimize student learning, designers must take into consideration which elements will enhance student learning and which ones will hinder the process. In this study, the researcher presented two groups of engineering…

This study compares the experts and the novices to investigate their information processing in dealing with the different degrees of recognition of shape-match stimulus by measuring the event-related potentials (ERPs). ERPs were recorded while 20 designers and 20 novices made shape-match judgments for table and chair sets. All of the tables were…

Competition judges are often selected for their expertise, under the belief that a high level of performance expertise should enable accurate judgments of the competitors. Contrary to this assumption, we find evidence that expertise can reduce judgment accuracy. Adaptation level theory proposes that discriminatory capacity decreases with greater…

Mathematics textbooks are a significant pedagogical tool, particularly in light of the growing interest in "flipped" classrooms. However, there has been little research on how mathematics students read and comprehend textbooks. This article uses the ideas of the implied reader, sense-making frames, and sense-making gaps to analyze…

This report presents dual analyses of an undergraduate student, Cassie, whose work provides nice contrasts between Grounded Theory (GT) analysis and Knowledge Analysis (KA). The analyses highlight particular methodological differences, such as grain size of findings, positioning of novices and more general implications about expert-novice studies.…

Organic chemistry students struggle with multiple aspects of reaction mechanisms and the curved arrow notation used by organic chemists. Many faculty believe that an understanding of nucleophiles and electrophiles, among other concepts, is required before students can develop fluency with the electronpushing formalism (EPF). An expert concept map…
