What is a real story? Investigating the perceptions of Key Stage One children

This small‐scale piece of research stemmed from a larger study on oral storytelling and the responses of children to stories told and read to them. In the larger study several children expressed preferences for stories from picture books, as told stories were not real stories. This concept of real stories and what constitutes a real story in the eyes of an infant child, aged between five and seven years, is what led to the basis of the research. One hundred and thirty‐five children between the ages of five and seven years old were involved in the research. The investigation was conducted in three different schools in South Wales, UK. It was hoped that the research would give some insights into the literacy habits of children today. The children were asked some basic questions about home practices relating to storytelling and story‐reading and about preferences in relation to oral stories and picture books. Finally they were asked if they thought oral tales were real stories. This essay gives an overview of some of the literacy practices of the children and deliberates on their comments as they wrestle with the concept of a real story.     

Constraints on conceptual development: a case study of the acquisition of folkbiological and folksociological knowledge in Madagascar

How different are the concepts held by children who grow up in a North American middle class neighborhood and by children who grow up in a rural Malagasy fishing village? By probing Malagasy children's and adults' conceptual representations of human and animal kind, biological inheritance, innate potential and family relations, the studies presented in this Monograph address current debates about the acquisition and the nature of concepts in the domains of folkbiology and folksociology. Cross-cultural and developmental studies of this kind bear on the hypothesis that conceptual development in these domains is supported and constrained by innate conceptual content. If so, one would expect cross-cultural universality in the relevant adult concepts and their early emergence in childhood regardless of widely different input conditions. We chose to conduct these studies among the Vezo of Madagascar because the ethnographic literature has attributed to them folkbiological and folksociological theories that are radically different, even in commensurable, with those of North American adults. Vezo therefore provide a challenging test for the innate conceptual constraints hypothesis.Four studies probed aspects of biological and sociological reasoning of Vezo children, adolescents and adults through a number of adoption scenarios. Despite ethnographic reports to the contrary, we found cross-cultural convergence in adult concepts of biological inheritance, but the pattern of development of this concept differed greatly from that seen in North America. Moreover, in agreement with the ethnographic literature, we found that Vezo adults have constructed a distinctive theory of social group identity. However, we found that children's reasoning in this domain is under the influence of endogenous constraints that are overturned in the course of development. Finally, we found cross-cultural convergence in adults' concept of species kind, as well as evidence for the early emergence of this concept. In light of these findings, we discuss the nature of the constraints on children's conceptual representations, the developmental process through which the adults' concepts are constructed, and relations between Vezotheories of folkbiology and folksociology.     

Random Permutation Testing Applied to Measurement Invariance Testing with Ordered-Categorical Indicators

We describe and evaluate a random permutation test of measurement invariance with ordered-categorical data. To calculate a p-value for the observed (?)χ², an empirical reference distribution is built by repeatedly shuffling the grouping variable, then saving the χ² from a configural model, or the ?χ² between configural and scalar-invariance models, fitted to each permuted dataset. The current gold standard in this context is a robust mean- and variance-adjusted ?χ² test proposed by Satorra (2000), which yields inflated Type I errors, particularly when thresholds are asymmetric, unless samples sizes are quite large (Bandalos, 2014; Sass et al., 2014). In a Monte Carlo simulation, we compare permutation to three implementations of Satorra’s robust χ² across a variety of conditions evaluating configural and scalar invariance. Results suggest permutation can better control Type I error rates while providing comparable power under conditions that the standard robust test yields inflated errors.     

A theory of instruction for introductory programming skills

ABSTRACT

Background and Context: Current introductory instruction fails to identify, structure, and sequence the many skills involved in programming.

Objective: We proposed a theory which identifies four distinct skills that novices learn incrementally. These skills are tracing, writing syntax, comprehending templates (reusable abstractions of programming knowledge), and writing code with templates. We theorized that explicit instruction of these skills decreases cognitive demand.

Method: We conducted an exploratory mixed-methods study and compared students’ exercise completion rates, error rates, ability to explain code, and engagement when learning to program. We compared material that reflects this theory to more traditional material that does not distinguish between skills.

Findings: Teaching skills incrementally resulted in improved completion rate on practice exercises, and decreased error rate and improved understanding of the post-test.

Implications: By structuring programming skills such that they can be taught explicitly and incrementally, we can inform instructional design and improve future research on understanding how novice programmers develop understanding.

The Right “Fit”: Exploring Science Teacher Candidates’ Approaches to Natural Selection Within a Clinical Simulation

Teachers and students struggle with the complexities surrounding the evolution of species and the process of natural selection. This article examines how science teacher candidates (STCs) engage in a clinical simulation that foregrounds two common challenges associated with natural selection—students’ understanding of “survival of the fittest” and the variation of species over time. We outline the medical education pedagogy of clinical simulations and its recent diffusion to teacher education. Then, we outline the study that situates each STC in a one-to-one interaction with a standardized student who is struggling to accurately interpret natural selection concepts. In simulation with the standardized student, each STC is challenged to recognize content misconceptions and respond with appropriate instructional strategies and accurate explanations. Findings and implications center on the STCs’ instructional practices in the simulation and the use of clinical learning environments to foster science teacher learning.     

A Person-Centered Approach to Students' Evaluations of Perceived Fear Appeals and Their Association With Engagement

A person-centered approach was employed to investigate how students' evaluation of perceived teacher utility value messages, i.e., fear appeals, as a threat and as a challenge, combined within individuals and how these combinations related to student engagement. Two studies were conducted with students in their final two years of secondary education. Empirically distinct clusters emerged at two time points in the academic year. Evaluating the message in the fear appeal at a higher level of challenge than threat was beneficial. Unexpectedly, high threat was associated with high engagement, as long as high challenge was also present, however, this combination was also related to high emotional disaffection. Moderate threat combined with moderate challenge had the most detrimental relationship with student engagement. Educational interventions should aim to increase the likelihood of a challenge evaluation.
