Acetabular fractures are a real challenge for junior doctors as well as experienced orthopedic surgeons. Correct fracture classification is crucial for appreciating the fracture type, surgical planning, and predicting prognosis. Although three-dimensional (3D) tutorial is believed to improve the understanding of the complex anatomy structure,…

This study addressed the concept of reading instructional level. First, we reviewed the history of the concept, including some recent criticisms of its validity (Schwanenflugel & Knapp, 2017; Shanahan, 2014). Next, we examined, from an instructional-level perspective, the oral reading performance of 248 third graders. We divided the sample…

In this paper, we will first discuss two current meta-theories dealing with different, aspects of "truth". The first metatheory conceives of truth in terms of coherence (rationality, consistency): a body of knowledge is true when it contains no inconsistencies and has at least some credibility. The second metatheory conceives of truth as…

In recent years, there has been a proliferation of adaptive learner models that seek to predict student correctness. Improvements on earlier models have shown that separate predictors for prior successes, failures, and recent performance further improve fit while remaining interpretable. However, students who engage in "gaming" or other…

Purpose: An increasing number of anomia treatment studies have coupled traditional word retrieval accuracy outcome measures with more fine-grained analysis of word retrieval errors to allow for more comprehensive measurement of treatment-induced changes in word retrieval. The aim of this study was to examine changes in picture naming errors after…

Pedometers are commonly used instruments that measure activity in children. While pedometers were designed to measure activity during walking, children often engage in other locomotor movements, such as skipping, galloping, and sliding. This study assessed the accuracy of two pedometers in children performing these movements and quantified the…

Purpose: The study was designed primarily to determine if the use of hearing aids (HAs) in individuals with hearing impairment in China would affect their speechreading performance. Method: Sixty-seven young adults with hearing impairment with HAs and 78 young adults with hearing impairment without HAs completed newly developed Chinese…

This study advances previous research about the effects of explicit instruction on second language (L2) development by examining learners' use of verbal morphology following different types of explicit information (EI) and comprehension practice. We investigated the extent to which additional EI about the first language (L1) can reduce the effects…

Categorical perception (CP) effects manifest as faster or more accurate discrimination between objects that come from different categories compared with objects that come from the same category, controlling for the physical differences between the objects. The most popular explanations of CP effects have relied on perceptual warping causing…

This study presents a quantitative analysis of pre-emptive strategies used by first language speakers in talk addressed to second language speakers with moderate proficiency. The strategies identified in the conversations are reformulation, simplification, left-dislocation, and decomposition. The data come from simulated emergency calls in which…

Although self-regulated learning (SRL) is becoming increasingly important in modern educational contexts, disagreements exist regarding its measurement. One particularly important issue is whether self-reports represent valid ways to measure this process. Several researchers have advocated the use of behavioral indicators of SRL instead. An…

Individuals with autism spectrum disorder (ASD) are hypothesized to exhibit relative strengths in verbal and non-verbal reasoning and weaknesses in working memory and speed of information processing. The purpose of the present investigation was to determine the degree to which this cognitive profile as measured by the Wechsler Intelligence Scale…

This study continues a line of inquiry testing strategies commonly used in melodic dictation. Undergraduate music majors (N = 44) completed short tonal dictations in a within-subjects design to determine effects of silence, audible sounds, and singing on test scores. Participants scored significantly lower when required to sing the melody prior to…

This study described the ability of five children with Developmental Language Disorder (DLD) to relate the mental states of story characters in two conditions: spontaneous story generation and in response to direct questions. Children spontaneously generated stories from wordless picture books. Subsequently, they were prompted, "What was…

Over half of community college students place into developmental education, resulting in significant financial costs. We extend previous research demonstrating that using placement tests to assign students into developmental courses results in frequent misplacement. We use Florida data to explore the extent to which students are misplaced into…
