Background: Investigating the relationship between the human body and its spatial environment is a critical component in understanding the process of acquiring spatial knowledge. However, few empirical evaluations have looked at how the visual accessibility of an environment affects spatial learning. To address this gap, this paper focuses on…

Purpose: This study examined whether monolingual German-speaking preschool children with developmental language disorder (DLD) were facilitated by the presence of case-marking cues in their interpretation of German subject and object "welcher" ("which")-questions, as reported for their typically developing peers. We also…

Spelling words accurately is not an easy process. Instead, it is a complex developmental skill. Due to this fact, several studies have recently investigated learners' spelling ability and how this skill develops in different stages. The main purpose of this study is to examine the developmental nature of Saudi intermediate school students'…

This study investigated writing errors committed by engineering students at AnNajah National University in Palestine and compared these errors based on school type. It analyzed errors in essays of 54 undergraduate students, 28 attended governmental schools, and 26 attended private schools. Errors were classified based on James's taxonomy. Results…

This study investigates the roles of indirect asynchronous electronic feedback (e-feedback) and direct corrective feedback (CF) on calque and collocation errors produced by Thai undergraduate students. The study also explores the factors influencing their ability to benefit from the feedback. Six cases were divided into two groups (Group 1: direct…

"Human factors" is an influential rationale in the UK national health service to understand mistakes, risk and safety. Although there have been studies examining its implications in workplaces, there has been little investigation of how it is taught, as a form of professional morality. This article draws on an observational study of…

Rankings of academics can be constructed in two different ways, either based on journal rankings or based on citations. Although citation-based rankings promise some fundamental advantages they are still not common in German-speaking business administration. However, the choice of the underlying database is crucial. This article argues that for…

This paper presents the findings of a study designed to explore qualification users' perceptions and experiences of reliability in the context of national assessment outcomes in England. The study consisted of 17 focus groups conducted across six sectors of qualification users: students, teachers, trainee teachers, job-seekers, employers and…

Student modeling is a fundamental concept applicable to a variety of intelligent tutoring systems (ITS). However, there is not a lot of practical guidance on how to construct and train such models. This paper compares two approaches for student modeling, Knowledge Tracing (KT) and Performance Factors Analysis (PFA), by evaluating their predictive…

Two experiments used error-detection to determine the reason for 3-year olds' perseverative errors on the postswitch phase of the Dimensional Change Card Sort. Results implied that perseveration cannot be attributed to difficulty inhibiting prepotent motor responses, but that changes in rule use between 3 and 5 years are more likely to increase…

Three experiments examined limitations in 5-year-olds' understanding of mental and linguistic representations. Findings indicated relatively poor performance on task involving two labels for one object, requiring children to treat another's knowledge as representing only some feature of its real referent: dice but not eraser. There were parallel…

Three experiments explored determinants of two-year olds' perseverative errors in a search task. Found that active search, even in the absence of observation, produced perseveration on post-switch trails, but mere observation did not. Results indicated that active search is required to elicit perseveration, which points to failures of response…

Experienced tennis teachers were marginally better at detecting errors in films of tennis forehand shots than were inexperienced teachers. (JD)

Think aloud data were gathered from 19 subjects solving three statistical problems. Good problem solvers differed from poor in that they (1) more often clarified essential concepts related to the problem, or (2) appeared to attend more closely to what was actually asked for in the problem. (Author/SJL)

Three experiments in which photo or video presentations could guide one's search for a hidden object showed that under certain circumstances even 24-month-olds displayed representational insight. The first two experiments replicated earlier findings of chance performance across 4 trials, with 24-month-olds performing above chance in 3 of 4…
