The contributions of ‘hot’ and ‘cool’ executive function to children's academic achievement, learning-related behaviors, and engagement in kindergarten

Executive functioning (EF) refers to higher order thought processes considered foundational for problem-solving. EF has both ‘cool’ cognitive and ‘hot’ emotional components. This study asks: (a) what are the relative contributions of ‘hot’ and ‘cool’ EF to children's academic achievement? (b) What are the relative contributions of ‘hot’ and ‘cool’ EF to learning-related classroom behaviors and observed engagement? (c) Do learning-related classroom behaviors and observed engagement account for the relation between EF and achievement? For a sample of 173 kindergarteners, cool EF predicted math achievement, learning-related classroom behaviors, and observed engagement. Hot EF did not predict any achievement or behavior outcomes when examined concurrently with cool EF. Children's classroom behavior did not account for the relation between cool EF and math achievement, suggesting cool EF and math performance are directly associated.     

Keeping their attention: Classroom practices associated with behavioral engagement in first grade mathematics classes in China and the United States

This study investigated variation in students’ behavioral engagement across mathematics classes in China and the United States. Student behavioral engagement was examined along with two aspects of the classroom (group size and teacher instructions given about classroom behavior). Video observational data were collected and coded over 1051 time intervals in 35-minute mathematics sessions in Chinese classrooms (n = 8) and comparable American classrooms (n = 7). Latent growth analyses revealed that overall, behavioral engagement declined over time, although the drop-off was dramatically sharper in American classrooms relative to Chinese classrooms. In addition, larger group size and the timing of teacher instructions (given before versus after the behavior) were significantly associated with increased engagement. This study revealed compelling cultural differences as well as patterns in student and teacher behaviors associated with students engaging in on-task behaviors in the classroom. Implications for ways to promote effective classroom behavior are discussed.

Problem-based learning and the development of metacognition

This study samples first year undergraduates from two programmes at a Hong Kong University (N = 66). One programme uses an entirely problem-based approach to learning and teaching, whilst the other uses more traditional methods. Using the Learning and Study Strategies Inventory (LASSI) as a measure of student perceptions of their thinking, or metacognition it explores differences in metacognitive development between each group of students between the beginning and end of their first year in each programme. The paper argues that, in addition to the formal learning context, everyday challenges emerging from the additional new social contexts provided by problem-based curricula provide fertile environments for the development of metacognition because whilst the highest ‘meta-level’ of cognition is usually not implicated when we receive an outside task and when the task solution is known, the meta-level does tend to be consulted when things go wrong or when the situation is new. In other words, when we are faced with finding solutions to a problem whether posed by the teacher as part of a problem-based curriculum or a new social environment, we are more likely to develop generic, as well as subject specific skills.     

What are secondary students’ expectations for teachers in virtual school environments?

A recent evaluation of the new North Carolina Virtual Public School (NCVPS) in the USA revealed numerous expectations for virtual school teachers from secondary students. Specifically, students expected their teachers to actually teach rather than moderate a course shell, supplement course shells with content and projects that illustrate relevance, provide for both content and peer interaction, and respond to questions and provide feedback quickly. The data suggest a possible content‐related interaction where a limited course shell can be bolstered by a proactive teacher, but potentially flounder among teachers who do not expect or know how to supplement an online course. Data further suggest a potential communication‐related interaction where increased opportunities for student–student and student–teacher interaction could potentially decrease the actual or perceived need for individualized attention that is particularly challenging for virtual teachers to provide. These results can be used to establish teacher expectations and design professional development experiences that prepare teachers to undertake divergent roles unique to online instruction.     

Effects of Exposure to Part-time Faculty on Community College Transfer

Over the past several decades, one of the most significant changes in the delivery of postsecondary education involves the dramatic increase in the use of contingent or part-time faculty. Although the increased use of part-time faculty within higher education makes sense from an administrative point of view, its use does not come without criticism. With community colleges representing a more convenient, affordable, and flexible educational option for a number of students, particularly those from disadvantaged backgrounds, examining how exposure to part-time faculty relates to students’ academic goals represents an important area of inquiry. This study draws from social and human capital frameworks and uses hierarchical generalized linear modeling (HGLM) to examine how exposure to part-time faculty relates to community college students’ likelihood of transferring to a four-year college or university. Findings suggest that students tend to be significantly less likely to transfer as their exposure to part-time faculty increases.     

Responding to the Voices of Homeless Preschool Children and Their Families

By utilizing all of the voices of homeless children and families we can gain a better understanding of their needs and thus be more effective in designing programs that can support them in becoming more independent. This article reviews the importance of the voices of homeless preschool children and their parents as well that of the professionals who work with them in developing responses to this problem. Strategies that empower homeless preschool children and their families are noted. These strategies include: quality preschool care, therapeutic practices that empower the entire family, case management schemes that provide support to homeless children and families, and societal changes that empower the family. Critical roles that early childhood education professionals can carry out in this empowerment process are delineated and discussed.     

Changing cognitions in parents of two‐year‐olds attending Scottish Sure Start centres

The study examined how preschool intervention programmes set up by three Scottish local authorities changed parents’ cognitions. Quantitative parent outcomes were measured using Parenting Daily Hassles Scales (N = 88). A matched comparison group of parents (N = 55) recruited from the same areas of disadvantage but whose children did not attend the intervention programmes also completed questionnaires. Qualitative outcomes were evaluated using semi‐structured interviews (N = 30). A significant group × time interaction effect was found for daily hassle cognitions, Parenting Task–Intensity, Challenging Behaviour–Frequency and Challenging Behaviour–Intensity, with comparison group parents showing an increase in their experience of hassles during the ‘terrible twos’ compared with intervention group parents. Complementary qualitative data indicated that intervention group parents had gained valuable new insights into their children’s behaviour, changing how they thought about their role as parents and their behavioural and developmental expectations of their children. Implications for parental engagement in preschool programmes are discussed.     

Tin Oxide Chemistry from the Last Decade of the Nineteenth Century to the First Decade of the Twenty-First Century: Towards the Development of a Big-Picture Approach to the Teaching and Learning of Chemistry While Focussing on a Specific Compound or Class of Compounds

The discovery of the electron in 1897 deeply impacted the nature of chemistry in the twentieth century. A revolution in the theoretical structure of chemistry as well as in the instrumental tools used in chemical analysis occurred as a result of this discovery. The impact of this revolution on tin oxide chemistry over approximately a 100 year period is the focus of this paper. Important questions addressed include the following: Are tin oxides of importance in our current society or are they only of quaint academic interest? In what way has chemistry as a discipline added to our understanding of the tin oxides and has this added any technological value to these compounds? Does the historical approach followed in this paper offer chemistry educators the opportunity to place current chemical knowledge in a broader epistemological framework? The impact of the answers to these questions on chemistry education is discussed.
