The Linguistic Mass/Count Distinction as an Indicator of Referent Categorization in Monolingual and Bilingual Children

This study examines the acquisition of the linguistic mass/count distinction in English by bilingual (Spanish-English) children. The goal of the study is to explore whether bilingual children, like their monolingual peers, can draw information from the linguistic context in which a new noun id presented to determine whether the new word refers to an object or a substance. Results indicate that at 7 years of age, even bilinguals who are strong in English do not yet draw such inferences. By 9 years of age, however, bilinguals who are strong in English have response patterns similar to those of their monolingual peers but bilinguals who have lower English abilities still lag behind their monolingual peers in drawing such inferences.     

Academic development by way of student affairs: reflections from the first fifty days on the job

ABSTRACT

This reflection on practice describes the first fifty days of a professional transition from student affairs into academic development. Campus collaborations, educational experiences, and holistic student learning are identified as professional parallels between these two institutional divisions. Professionals from student affairs can uniquely contribute to academic development because of their ability to view the campus as a working system and the student as a whole person. This reflection describes how a student affairs background can be a valuable addition and asset to academic development teams.     

Effects of a Game‐Based e‐Learning Module on Undergraduate Food Science Students’ Planned Behaviors Concerning Good Manufacturing Practices

Understanding the role of food science education in developing undergraduate students’ intentions to implement Good Manufacturing Practices (GMPs) may be a key strategy in developing the workforce's implementation of GMPs and other food safety programs. Previous research has demonstrated the effects of educational interventions on planned food safety behaviors in various settings; however, none have studied GMPs interventions and college students. This study applied the Theory of Planned Behavior (TPB) to evaluate the effects of a game‐based e‐learning module on undergraduate students’ planned behaviors concerning GMPs. Forty‐four participants were recruited from 42 food science clubs across the United States to complete a game‐based e‐learning module and pre‐ and posttest survey instruments. We compared changes in pre‐ and posttest scores using paired Wilcoxon signed rank tests and explored the role of GMP‐related knowledge and TPB constructs (attitudes, subjective norms, and perceived behavioral controls) in predicting students’ intentions to implement GMPs using multiple linear regression. We modeled pretest scores, posttest scores, and changes in scores while controlling for student demographic factors (for example, year in college, gender, and so on). Only participants’ knowledge and perceived behavioral controls significantly increased (P < 0.05) after completing the game‐based e‐learning module. Posttest regression models explained twice as much variance than pretest models (up to 54% total). Changes in intentions to implement GMPs were predicted by changes in subjective norms, perceived behavioral controls, and knowledge, as well as previous enrollment in food safety courses and interest in working in the food industry. The only predictive variables for both pre‐ and posttest scores were subjective norms, previous enrollment in food safety courses and interest in working in the food industry (P < 0.05). A discussion of how these results provide insights for food safety educators to optimize their teaching impacts was presented.     

Development and Implementation of a Food Safety Knowledge Instrument

ABSTRACT:  Little is known about the food safety knowledge of young adults. In addition, few knowledge questionnaires and no comprehensive, criterion-referenced measure that assesses the full range of food safety knowledge could be identified. Without appropriate, valid, and reliable measures and baseline data, it is difficult to develop and implement effective education efforts. Thus, the purpose of this study was to develop a comprehensive, valid, reliable food safety knowledge questionnaire. Questionnaire development followed this process: 1) use of published reports and input from experts in food safety and sanitation (n = 7) to identify key food safety concepts; 2) development of a question bank (n = 101) assessing knowledge of key concepts (i.e., cross contamination prevention'disinfection procedures; safe times/temperatures for cooking/storing foods; groups at greatest risk for foodborne disease; foods that increase risk of foodborne disease; and foodborne disease pathogens); 3) refinement of initial questions by experts; 4) questionnaire pretest with young adults (n = 180) and refinement; 5) questionnaire pilot test (n = 126) and refinement; 6) final expert review and refinement; and 7) conversion into an online survey. Young adults (n = 4343, mean age 19.9 ± 1.7SD years) from 21 universities and colleges across the country completed the questionnaire. Item analysis was used to determine the overall quality of the test and identify improvements needed. Livingston's coefficient of reliability for criterion-referenced tests was 0.92. The questionnaire met or exceeded generally recognized standards of reliability and validity. This questionnaire could be useful in baseline assessment of food safety knowledge and measurement of knowledge gained after an educational intervention in adults.     

Individual differences in children's writing: A function of working memory or reading or both processes?

The purpose of this study was to investigate whether a general or specific working memory (WM) system is related to writing and whether individual differences in reading and/or processing efficiency underlie the correlations between WM and writing. Two studies correlated WM with writing (Test of Written Language-TOWL) and reading measures. In Study 1, WM was correlated significantly with a number of writing measures, particularly to those measures related to text generation. Working-memory also contributed unique variance to writing, beyond what is predicted by reading comprehension. Study 2 compared the correlations of verbal and visual-spatial WM measures with the TOWL under initial and enhanced memory processing (dynamic assessment) conditions. The coefficients were statistically comparable between initial and enhanced processing conditions, suggesting that individual differences in processing efficiency do not account for the correlations between WM and writing. Overall, the results indicated that (a) WM measures contribute unique variance to writing, especially text generation, and (b) working memory performance improves under gain conditions, but this enhanced processing efficiency did not appear to mediate the links between WM and writing. Taken together, the two studies support a general capacity explanation for the relationship between working memory and text generation.     

Classroom Process and Practices in Public Pre-K Programs: Describing and Predicting Educational Opportunities in the Early Learning Sector

Research Findings: The present study used data from 117 publicly funded preschool classrooms within a large, diverse, suburban county to describe teacher practices and child engagement along with classroom activity settings and children’s exposure to instructional content. Practice or Policy: Results from this investigation revealed that children spent the largest share of the day in teacher-directed whole-group instruction and in free play and very little time was spent in individual and small-group settings. Although a 3rd of the school day was dedicated to academic activities, there were few opportunities for socioemotional learning, and children spent roughly a 3rd of the school day in routines/transitions and meals. Few differences emerged in the classroom observations across school- and community-based programs; however, more educated and experienced teachers spent more time teaching and in teacher-directed instruction.     

Phonological awareness,speech development,and letter knowledge in preschool children

Phonological awareness has been shown to be one of the most reliable predictors and associates of reading ability. In an attempt to better understand its development, we have examined the interrelations of speech skills and letter knowledge to the phonological awareness and early reading skills of 99 preschool children. We found that phoneme awareness, but not rhyme awareness, correlated with early reading measures. We further found that phoneme manipulation was closely associated with letter knowledge and with letter sound knowledge, in particular, where rhyme awareness was closely linked with speech perception and vocabulary. Phoneme judgment fell in between. The overall pattern of results is consistent with phonological representation as an important factor in the complex relationship between preschool children’s phonological awareness, their emerging knowledge of the orthography, and their developing speech skills. However, where rhyme awareness is a concomitant of speech and vocabulary development, phoneme awareness more clearly associates with the products of literacy experience.     

Does chroma on the line increase attention to the line in pigeons?

Two groups of pigeons received differential discrimination training on the presence vs absence of a vertical line on a white surround. The line was green for one group and black for a second group. Generalization tests along the angularity dimension showed that both green and black lines produced equally steep gradients. The results suggested that the addition of chroma to the line does not increase attention to the line.     

Enhancing the quality of early childhood education: A follow-up evaluation of an experiential, collaborative training model for head start

The study is a follow-up evaluation of a Collaborative Training curriculum for Head Start. The previous curriculum was enhanced by adding parent exemplars and demonstrations in trainees' classrooms. Two Head Start teachers and two parent volunteers from each of 70 classrooms were randomly assigned to either the enhanced Collaborative Training (CT) or Workshop Training (WT) approach. CT teachers and parents were involved conjointly in experiential training that included receiving guided practice and feedback from exemplary peers. WT consisted of a series of workshops conducted by outside trainers for separate groups of parents and teachers. Training methods were compared with respect to (a) trainees' reports of satisfaction with training and collaboration, and (b) observed levels of adult-adult and adult-child classroom interactions. CT teachers and parents reported significantly greater levels of satisfaction with the training, as well as significantly greater levels of collaboration than WT participants. Teacher-teacher and parent-teacher observations indicate that CT trainees showed higher levels of positive classroom interactions than WT trainees. With respect to adultchild classroom interactions, CT teachers demonstrated significantly more praise, supportive physical contact, and positive interactions in instruction than WT teachers. CT parents showed higher levels of adult-child classroom interactions across all observed categories compared to their WT counterparts. Implications of these findings for further research were discussed.
