Objective: To determine whether differences in nutrition knowledge affected how women (a high-involvement group) interpreted intrinsic cues (ingredient list) and extrinsic cues ("all natural" label) on food labels. Methods: A 2 (intrinsic cue) x 2 (extrinsic cue) x 2 (nutrition knowledge expert vs novice) within-subject factorial design…

Paramedic students need to acquire knowledge and skills necessary to perform basic as well as complex clinical skills, to ensure patient safety, and to manage sophisticated equipment. Time and resource pressures on students, teaching staff and institutions have led health professional educators to develop and embrace alternative opportunities such…

The nature of expertise in astronomy was investigated across a broad spectrum of ages and experience in China and New Zealand. Five hypotheses (capable of quantification and statistical analysis) were used to probe types of expertise identified by previous researchers: (a) domain-specific knowledge-skill in the use of scientific vocabulary and…

In this article we report on the effects of a digital intervention on the development of algebraic expertise of 17-18 year old students in the Netherlands. The question to be answered was whether the intervention would be effective and what factors influenced the outcome. With notions of formative assessment and symbol sense as guiding theoretical…

Do prodigies have extraordinary innate talent or do they just start very early and get much practice? Why do relatively few become eminent as adults? Is it because early and later success often need somewhat different abilities and gatekeepers rule? International chess is a good test domain for both issues because it has objective longitudinal…

This paper presents research findings related to the "Dynamic Enhanced Evaluation of Problem Solving (DEEP)" (Spector & Koszalka, 2004) methodology for assessing how participants conceptualize ill-defined problems in biology using annotated concept maps. The methodology engages highly experienced (expert) and less experienced…

The following empirical study examines the acquisition of expertise. The model structures in the domain of empirical methodologies were examined in a time period of two semesters. At each measurement point (N = 5), the model structures of the reference groups were compared with those of the group of learners. The group of learners consisted of (N…

This article reports on differences between expert and aspiring principals. Following the work of Leithwood and colleagues, we asked expert and aspiring principals to respond to ill-structured written problem scenarios. Our sample of 44 included 20 expert principals and 24 aspiring principals. The aspiring principals were from a cohort of…

In laboratory studies of social referencing, infants as young as 12 months have been reported to prefer looking at the experimenter over the caregiver for clarifying information.

This paper aims to show how training in psychology leads students (at the beginning and the end of their studies) to consider that psychological disorders result from dispositional factors specific to the patients, particularly in therapeutic failure (fundamental attribution error and hindsight bias). Faced with a clinical case of a somatic…

Despite the acknowledged complexity of the expertise of teacher educators (Cochran-Smith, M. (2003). Learning and unlearning: the education of teacher educators. "Teaching and Teacher Education," 19, 5--28), there is limited research attending to what teacher educators need to know and how they develop this expertise. This self-study draws from…

The purpose of this study is to understand how teacher identity influences elementary teachers' science practices from multiple perspective---the teacher's self-reported identity, the researcher's perspective, and the students' perspectives. Two frameworks on identity were synthesized and used in this research. The first, developed by Gee…

Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder characterised by high levels of inattention, hyperactivity and impulsivity that are present before the age of seven years, seen in a range of situations, inconsistent with the child's developmental level and causing social or academic impairment. Parent training…
