This article asserts that a carefully administered informal reading inventory (IRI) provides important information on low-achieving readers that is "not" provided by an end-of-grade standardized reading test. Using case studies of students' IRI performance, we address the concept of instructional level and the necessity of teaching low…

An Australia-wide consensus was reached on seven core concepts of physiology, one of which was cell-cell communication. Three physiology educators from a "core concepts" Delphi task force "unpacked" this core concept into seven different themes and 60 subthemes. Cell-cell communication, previously unpacked and validated, was…

This qualitative study examines the influence of a 3-year professional development project for middle school mathematics, science, and special education teachers focused on integrating science, mathematics, and engineering in classroom instruction on participants' understandings of productive struggle in learning. Multi-disciplinary teams of…

Many Aboriginal Australian communities are undergoing language shift from traditional Indigenous languages to contact varieties such as Kriol, an English-lexified Creole. Kriol is reportedly characterised by lexical items with highly variable phonological specifications, and variable implementation of voicing and manner contrasts in obstruents…

Purpose: The goal of this study was to develop and validate a new corpus of sentences without semantic context to facilitate research aimed at isolating the effects of semantic context in speech perception. Method: The newly developed corpus contains nonsensical sentences but is matched in vocabulary and syntactic structure to the existing Basic…

Dual display desktop computers are becoming more prevalent in the home, workplace, and schools, yet there has been little research into how learning and productivity are impacted by having a second display. One useful method in exploring this question is to measure cognitive load during an intensive learning event. This study compared perceived…

This article reviews the evidence on the extent to which experts' perceptions of item difficulties, captured using comparative judgement, can predict empirical item difficulties. This evidence is drawn from existing published studies on this topic and also from statistical analysis of data held by Cambridge Assessment. Having reviewed the…

We investigated how two cues to contrast--beat gesture and contrastive pitch accenting--affect comprehenders' cognitive load during processing of spoken referring expressions. In two visual-world experiments, we orthogonally manipulated the presence of these cues and their felicity, or fit, with the local (sentence-level) referential context in…

Anxiety alters how we perceive the world and can alter aspects of cognitive performance. Prominent theories of anxiety suggest that the effect of anxiety on cognition is due to anxious thoughts "overloading" limited cognitive resources, competing with other processes. If this is so, then a cognitive load manipulation should impact…

Cognitive learning complexity identification of assessment questions is an essential task in the domain of education, as it helps both the teacher and the learner to discover the thinking process required to answer a given question. Bloom's Taxonomy cognitive levels are considered as a benchmark standard for the classification of cognitive…

This study analyzed the development of postural control and the cost of the cognitive task on postural control in the bipedal standing position during childhood. Sixty-six normally developed children divided into four groups by age participated in this study. Single (ST) and dual-tasks (DT) were conducted in the bipedal standing position with eyes…

Difficulties in learning (and thus teaching) statistical inference are well reported in the literature. We argue the problem emanates not only from the way in which statistical inference is taught but also from what exactly is taught as statistical inference. What makes statistical inference difficult to understand is that it contains two logics…

Purpose: This article describes patterns of speech modifications produced by talkers as a function of the degree of hearing impairment of communication partners during naturalistic conversations in noise. An explanation of observed speech modifications is proposed in terms of a generalization of the concept of effort. This account complements…

Pearson product-moment correlation coefficient between item g and test score X, known as item-test or item-total correlation ("Rit"), and item-rest correlation ("Rir") are two of the most used classical estimators for item discrimination power (IDP). Both "Rit" and "Rir" underestimate IDP caused by the…

Through providing an external support to speech, gesture observation may benefit a student's learning in a variety of areas, including narrative comprehension. Across two studies, we investigated factors that could moderate when gestures are most beneficial to narrative comprehension, including gesture type, task difficulty, and age, in order to…
