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…

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…

A historic period of state divestment in public higher education, exacerbated by the "Great Recession" and attendant financial repercussions, has significantly altered public higher education financing. The most significant impact has been cost shift from the state to students via increasing tuition rates. These changes threaten student…

Although several decades of research has highlighted the contribution of classroom behaviors to students' mathematics and reading performance, this relation with regard to writing performance has been examined to a lesser extent. Therefore, this study sought to examine a wide range of classroom behaviors as predictors of written expression,…

We assessed nonword repetition (NWR) skills in 7-9 year-old children with dyslexia (dyslexia-only), developmental language disorder (DLD-only), co-occurring DLD+dyslexia, and typical development (TD) with a norm-referenced and an experimental task. The experimental task manipulated phonemic variability (dissimilarity among consonant phonemes…

This study aimed to investigate children's potential for reasoning by analogy utilizing a newly-developed computerized dynamic test, and the potential differential influence of executive functions (cognitive flexibility, attention, and planning) on static and dynamic measures of analogical reasoning. Participants included 64 children (mean age =…

The study was conducted at a vocational high school in Ankara during the academic year of 2018-2019 based on the key concepts regarding the units in the chemistry curriculum for 9th grade. The purpose of the study was to investigate whether 9th grade students recognized the key concepts in chemistry units of first and second semester, and how…

It is obvious that the textbooks play a key role in enhancing the quality of teaching and learning. The good quality textbooks must meet the criteria or standard as a textbook. This paper aims to describe the accuracy of materials provided in the "Bahasa Indonesia" textbook for the first grade of Senior High School curriculum of 2013.…
