Understanding the Program Effectiveness of Early Mathematics Interventions for Prekindergarten and Kindergarten Environments: A Meta-Analytic Review

Research Findings: The early childhood years are critical in developing early mathematics skills, but the opportunities one has to learn mathematics tend to be limited, preventing the development of significant mathematics learning. By conducting a meta-analysis of 29 experimental and quasi-experimental studies that have been published since 2000, this study extends beyond prior evaluations of early mathematics programs for prekindergarten and kindergarten environments by quantifying program effectiveness in terms of effect sizes and examining 6 aspects of these programs. We found an overall moderate to large effect size. There was a tendency for programs to produce larger effects when they (a) targeted a single content strand, (b) presented content 120 to 150 min per week, (c) designed programs for the prekindergarten environment, (d) presented content individually to children, and (e) used researcher-made mathematics assessments. Practice or Policy: Early mathematics programs can be designed to be both developmentally appropriate and highly effective. The goal of this meta-analysis was to reveal these programs to early development and education professionals so that they understand some of the factors that might explain why some produced stronger effects than others.     

Assessment of progressively delayed prompts on guided skill learning in rats

We examined the controlling factors that allow a prompted skill to become autonomous in a discrete-trials implementation of Touchette’s (1971) progressively delayed prompting procedure, but our subjects were rats rather than children with disabilities. Our prompted skill was a left-right lever-press sequence guided by two panel lights. We manipulated (a) the effectiveness of the guiding lights prompt and (b) the presence or absence of a progressively delayed prompt in four groups of rats. The less effective prompt yielded greater autonomy than the more effective prompt. The ability of the progressively delayed prompt procedure to produce behavioral autonomy depended upon characteristics of the obtained delay (trial duration) rather than on the pending prompt. Sequence accuracy was reliably higher in unprompted trials than in prompted trials, and this difference was maintained in the 2 groups that received no prompts but yielded equivalent trial durations. Overall sequence accuracy decreased systematically as trial duration increased. Shorter trials and their greater accuracy were correlated with higher overall reinforcement rates for faster responding. Waiting for delayed prompts (even if no actual prompt was provided) was associated with lower overall reinforcement rate by decreasing accuracy and by lengthening trials. These findings extend results from previous studies regarding the controlling factors in delayed prompting procedures applied to children with disabilities.     

Longitudinal Effects of PostDivorce Interparental Conflict on Children’s Mental Health Problems Through Fear of Abandonment: Does Parenting Quality Play a Buffering Role?

In a sample of 559 children (ages 9–18), researchers investigated whether: (a) fear of abandonment mediated the association between postdivorce interparental conflict (IPC) and mental health problems, and (b) parent–child relationship quality moderated the association between IPC and fear of abandonment. Mediation analyses indicated that pretest IPC predicted fear of abandonment 3 months later, which then predicted child- and teacher-reported mental health problems 10 months later. The hypothesized protective effect of a high-quality parent–child relationship was not observed. IPC predicted fear of abandonment for all children, except for those with low- and moderate-quality father–child relationships, for whom IPC was not significantly related to fear of abandonment. Findings highlight the need to optimize child coping programs and improve parenting-after-divorce programs to reduce IPC.     

“Hello, goodbye”: Exploring the phenomenon of leaving teaching early

High teacher attrition rates hinder schools in their ability to provide quality instruction. This study seeks to understand why teachers leave early in their careers (within the first 5 years) using a mixed methods approach that combined 50 in-depth interviews with 15 public and 10 Catholic school teachers in the United States who left early with statistical analyses of public and Catholic school early leavers’ responses in the national Schools and Staffing and Teacher Follow-up surveys. This study argues that to understand why teachers leave early requires examining teachers’ entire experiences throughout their short time in the profession. A framework informed by sociocultural and commitment theories was developed through systematic analysis of the interview and survey data providing a complex approach for examining the phenomenon of early leaving. Findings suggest that teachers’ career decisions were influenced by the unique public and Catholic school cultures, as well as their commitment to teaching, their teaching experiences, and their beliefs and values. Differences between public and Catholic early leaver experiences are discussed.     

A Three-Tier Diagnostic Test to Assess Pre-Service Teachers’ Misconceptions about Global Warming,Greenhouse Effect,Ozone Layer Depletion,and Acid Rain

This study describes the development and validation of a three-tier multiple-choice diagnostic test, the atmosphere-related environmental problems diagnostic test (AREPDiT), to reveal common misconceptions of global warming (GW), greenhouse effect (GE), ozone layer depletion (OLD), and acid rain (AR). The development of a two-tier diagnostic test procedure as described by Treagust constitutes the framework for this study. To differentiate a lack of knowledge from a misconception, a certainty response index is added as a third tier to each item. Based on propositional knowledge statements, related literature, and the identified misconceptions gathered initially from 157 pre-service teachers, the AREPDiT was constructed and administered to 256 pre-service teachers. The Cronbach alpha reliability coefficient of the pre-service teachers’ scores was estimated to be 0.74. Content and face validations were established by senior experts. A moderate positive correlation between the participants’ both-tiers scores and their certainty scores indicated evidence for construct validity. Therefore, the AREPDiT is a reliable and valid instrument not only to identify pre-service teachers’ misconceptions about GW, GE, OLD, and AR but also to differentiate these misconceptions from lack of knowledge. The results also reveal that a majority of the respondents demonstrated limited understandings about atmosphere-related environmental problems and held six common misconceptions. Future studies could test the AREPDiT as a tool for assessing the misconceptions held by pre-service teachers from different programs as well as in-service teachers and high school students.     

Developing and executing strategy: Using the balanced scorecard for alignment and accountability

The balanced scorecard is a strategic performance management system that charts the course and evaluates the strategic goals of an organization. Practitioners in the field of performance improvement are results focused, with efforts purposefully channeled toward achievement of successful outcomes for their clients. Using a systematic and systemic approach, performance improvement practitioners are uniquely qualified to guide their practice using a balanced scorecard as a tool toward achieving measurable and results‐focused objectives.     

Hey,HPT practitioner! Talk to me

It is important to clearly articulate what the essence of human performance technology (HPT) is about. Too often we are caught in our own jargon and confuse our clients and jeopardize appropriate outcomes. A group of graduate students in an introductory HPT class responded to an assignment to explain to other professionals what human performance practitioners do. Their thoughts, written in their own voices, are reflected here.
