Using coaching to increase preschool teachers’ use of emergent literacy teaching strategies

This single-subject study assessed the effects of in-classroom coaching on early childhood teachers’ use of emergent literacy teaching strategies. Teaching strategies were grouped into clusters related to oral language and comprehension of text, phonological awareness and alphabetic principle, and print concepts and written language, with coaching being applied to each cluster separately. The coaching process included two primary components: a brief initial meeting to introduce teaching strategies in the cluster, and semi-weekly observation with follow-up discussion using data collected during the observation. A third, booster component was added when the teacher did not achieve a pre-established criterion. Participants were five early childhood teachers, three in child care programs and two in public school pre-kindergarten programs. The intervention phase lasted approximately 6 weeks for each teacher. Results indicated that this approach to coaching was effective for increasing the number of teaching strategies that teachers used in each cluster. Individual differences among teachers are discussed, and implications for future research and practice are explored.     

American adults' knowledge of exercise recommendations

Physical inactivity is a major risk factor for cardiovascular disease, stroke, hypertension, diabetes, obesity, osteoporosis, and some cancers. Approximately 950,000 Americans die annually from cardiovascular diseases. The purpose of this study was to determine whether American adults know which traditional and lifestyle physical activities affect health and how they should be physically active to achieve a health benefit. Secondary purposes were to determine whether this knowledge is a function of gender, ethnicity, education, or age and if those who are sufficiently active for a health benefit possess different knowledge levels than those not sufficiently active for a health benefit. Items based on the Centers for Disease Control and Prevention/American College of Sports Medicine principles included knowledge of exercise guidelines and traditional and lifestyle physical activities. This information was obtained from 20 questions that were part of a national random telephone survey of 2,002 American households in the 48 contiguous states and the District of Columbia. Respondents were most aware of traditional physical activities (M = 94%) that provide a health benefit and less aware of specific exercise guidelines (M = 68%) and lifestyle physical activities (M = 71%) that can result in a health benefit. Knowledge was not related to physical activity behavior sufficient for a health benefit and only slightly related to ethnicity, education, and age. These data suggest that physical activity knowledge alone is not sufficient to elicit a behavior; however, it provides educators with an understanding of the public's physical activity knowledge that could be helpful in developing health promotion and physical activity interventions.     

From Peasant to Princess: A Standards Conversion Story with a Twist

The first author, a student in a graduate children’s literature class, designed a project to locate “good” mathematics-based children’s literature selections. However, the reference tools usually consulted (e.g., Books in Print) to locate books by topic were of little help, and those she located under individual mathematics topics were mostly traditional mathematics books rather than good read-aloud selections. Consequently, she perused the university library’s sizeable juvenile collection to find books that would meet her selection criteria. This article describes the influence of two landmark documents for mathematics teaching and learning—Curriculum and Evaluation Standards for School Mathematics (National Council of Teachers of Mathematics [NCTM], 1989) and Principles and Standards for School Mathematics (NCTM, 2000)—as she engaged in the process.

A Bourdieusian perspective on becoming and being a postgraduate supervisor: the role of capital

The objective of this paper is to map the role of capital in the process of learning to become a postgraduate supervisor. Economic, technological and geopolitical changes in higher education call into question previous assumptions about supervision. Supervision is no longer primarily seen as an intellectual and social enterprise but is increasingly seen as professional work, where one's capital (or lack of) shapes the process of being and becoming a supervisor. It is frequently assumed that the students are the only ones learning in a supervisory relationship. Novice supervisors are, however, often left to their own devices to discover or learn the inherent rules, epistemologies and ontologies in becoming and being supervisors through a process of compromise and negotiation. In this article, we specifically focus on the need for novice supervisors to understand and navigate the field, and plot their career trajectories, as a constant exchange of different aspects of capital. This article is conceptual, rather than empirical. We suggest that it may be helpful to understand the field of supervision in a Bourdieusian sense, with specific reference to the role of (academic) capital in the formative processes of becoming and being a supervisor. We discuss social capital, gender and race, age, values, beliefs and experiences, as well as linguistic abilities, as factors influencing the individual habitus of the supervisor in relation to the doxa of the field.     

The Impact of Instructional Design on College Students’ Cognitive Load and Learning Outcomes in a Large Food Science and Human Nutrition Course

The effective design of course materials is critical for student learning, especially for large lecture introductory courses. This quantitative study was designed to explore the effect multimedia and content difficulty has on students’ cognitive load and learning outcomes. College students (n = 268) were randomized into 1 of 3 multimedia groups: text + graphics (Group 1–TG); audio + text + graphics (Group 2–ATG); or video + audio + text + graphics (Group 3–VATG). Participants answered a demographic survey and pretests before viewing 2 food science supplemental lecture materials (i.e., water mobility and amino acid structures) and completing the cognitive load instrument and post‐tests within a noncontrolled setting. Cognitive load scores were tabulated and compared using a 3 × 3 ANOVA and Tukey post hoc analysis across multimedia groups and food science supplemental lecture materials. Based on the post hoc, students in Group 1–TG had higher intrinsic cognitive load scores than Group 2–ATG (ANOVA, P < 0.05). Cognitive load and post‐test scores were tabulated and compared using a spearman correlation across groups. In Group 1–TG, students that reported less intrinsic cognitive load had higher post‐test scores. Also, students that reported more germane cognitive load had higher post‐test scores. In Groups 2–ATG and 3–VATG, students that reported less extraneous cognitive load had higher post‐test scores (ANOVA, P < 0.05).     

A perspective on magnetic microfluidics: Towards an intelligent future

Magnetic microfluidics has been gradually recognized as an area of its own. Both conventional microfluidic platforms have incorporated magnetic actuation for microfluidic operation and microscale object manipulation. Nonetheless, there is still much room for improvement after decades of development. In this Perspective, we first provide a quick review of existing magnetic microfluidic platforms with a focus on the magnetic tools and actuation mechanisms. Next, we discuss several emerging technologies, including magnetic microrobots, additive manufacture, and artificial intelligence, and their potential application in the future development of magnetic microfluidics. We believe that these technologies can eventually inspire highly functional magnetic tools for microfluidic manipulation and coordinated microfluidic control at the system level, which eventually drives magnetic microfluidics into an intelligent system for automated experimentation.     

Review of Ofcom policy investigation: “The future of children's television programming”

The review looks at the recent review of children's television broadcasting by the governmental regulator in the UK, Ofcom. It suggests that the research represents a valuable addition to the policy literature by filling the gap in previous research, particularly by providing an in-depth analysis of the economics of the sector. However, it questions the direct impact of the report on the subject matter if it is integrated (as proposed) into the more general review of Public Service Broadcasting.     

Evidence for Common Etiological Influences on Early Literacy Skills in Kindergarten

Understanding how the etiology of print awareness and phonological awareness are related to the etiology of decoding can provide insights into the development of word reading. To address this issue, we examined the degree of overlap among etiological influences of prereading skills in 1,252 twin pairs in kindergarten. Genetic, shared environmental, and nonshared environmental factors were significant for all three literacy phenotypes. The majority of genetic and shared environmental influence on decoding was due to common factors that included print awareness and phonological awareness. Notably, only a single genetic factor contributed to all three literacy phenotypes, but there was additional shared environmental influence common to phonological awareness and decoding. Findings suggest commonalities in the etiology of prereading literacy skills that could inform work on the development of reading skill.     

Teacher Classroom Management Skills and Pupil Behavior

An experimental group of 20 in service elementary teachers was trained using the Utah State University Classroom Management Protocol Modules, and compared before and after training with a control group of 9 teachers. Although the experimental teachers received more favorable post-training scores on all 13 classroom management behaviors covered in the modules, the differences were generally small and nonsignificant. The level of work involvement and deviant behavior of pupils of the experimental group teachers was also compared before and after the teachers had been trained. In recitation situations, pupil work involvement increased and deviant behavior decreased significantly. In seat work situations, pupil work involvement increased significantly, but no significant changes occurred in deviant behavior.
