Evaluating Discipline-Based Education Research for Promotion and Tenure

Discipline-based education research (DBER) is an emergent, interdisciplinary field of scholarship aimed at understanding and improving discipline-specific teaching and learning. The number of DBER faculty members in science, technology, engineering, and mathematics (STEM) departments has grown rapidly in recent years. Because the interdisciplinary nature of DBER involves social science, senior STEM faculty members may find it challenging to evaluate the quality or impact of DBER scholarship. This essay aims to address this issue by providing guidance on evaluating the scholarly accomplishments of DBER faculty members in a way that is useful to departmental colleagues and administrators during the tenure and promotion evaluation process.     

A Model for Developing and Testing Custom-Made Laboratory Manuals to Use with Food Chemistry and Food Analysis Courses

ABSTRACT: This project reports on a model for preparing food chemistry and food analysis laboratory manuals that provide a closer link between lecture material and laboratory exercises. Teaching effectiveness was also improved by evaluating the composition and eliminating duplication between these complementary courses. Utilizing the combination of personal experience and the scientific literature, laboratory exercises were developed and modified to fit with the lecture material. Labs were initially performed and critiqued by a graduate student. After making appropriate revisions, undergraduate students tested the labs under the graduate student's supervision and completed a questionnaire about their experiences. Based on the undergraduate feed-back, final revisions were made and custom laboratory manuals were printed. This project demonstrates one effective way for developing custom food science labs to parallel with lecture material.     

Addressing Disparities in Parent Education: Examining the Effects of Learn the Signs/Act Early Parent Education Materials on Parent Outcomes

Early intervention is critical for improved prognosis and quality of life for young children with developmental delays and disabilities. Yet, disparities persist among underserved families with young children. These disparities include knowledge of child development, use of medical providers as referral sources, and later diagnosis. The current study employed a mixed method, randomized controlled trial to examine participant outcomes among low-income, underserved families who received child development information. The information included the 42-page Milestone Moments booklet that was developed by the Centers for Disease Control and Prevention’s Learn the Signs/Act Early initiative. Participants (n = 108) included parents or legal guardians of children ages birth through 5 years. The participants were predominantly Black/African American (86 %) and female (90 %), and all had incomes below the federal poverty level. Study variables related to the location (home vs. child care center) and context (single session vs. extended visits) for delivering the information did not yield significant differences. Yet, there were clear findings that parents who received the booklet reported increased knowledge about child development, a decrease in concern about their own children’s developmental progress, and a positive perception of the booklet. On interview, parents reported learning new information about child development or being reminded of developmental information they had forgotten and the importance of following up with professionals when concerns arose. While not statistically significant, there was a consistent trend toward greater participant outcomes for parents who received materials in the child care setting relative to the home.     

A Regularized GLS for Structural Equation Modeling

Ill conditioning of covariance and weight matrices used in structural equation modeling (SEM) is a possible source of inadequate performance of SEM statistics in nonasymptotic samples. A maximum a posteriori (MAP) covariance matrix is proposed for weight matrix regularization in normal theory generalized least squares (GLS) estimation. Maximum likelihood (ML), GLS, and regularized GLS test statistics (RGLS and rGLS) are studied by simulation in a 15-variable, 3-factor model with 15 levels of sample size varying from 60 to 100,000. A key result showed that in terms of nominal rejection rates, RGLS outperformed ML at all sample sizes below 500, and GLS at most sample sizes below 500. In larger samples, their performance was equivalent. The second regularization methodology (rGLS) performed well asymptotically, but poorly in small samples. Regularization in SEM deserves further study.     

Gross motor teaching in preschool education: where,what and how do Singapore educators teach? (Enseñanza de la motricidad gruesa en educación infantil: ¿dónde,qué y cómo enseñan las maestras en Singapur?)

ABSTRACT

Fostering the development of gross motor (GM) skills is important in itself and beneficial for the holistic development of children. While early childhood curriculum frameworks for GM teaching have been recently articulated, there is limited research on actual pedagogical practices. This study explored GM teaching practices in Singapore Kindergarten 1 classrooms (4–5 years), focusing on where (indoors vs outdoors), what (types of GM skills) and how (teaching strategies and opportunities for practice) preschool educators teach. The study is part of a longitudinal project in which 108 Kindergarten 1 classrooms were observed and videotaped during a full ‘typical day’ (3–4 hours). GM teaching was observed to occur predominantly indoors. Non-locomotor skills were the most frequently taught to children, followed by locomotor and manipulative skills. Many educators were observed using explicit teaching strategies before and during GM activities, with low involvement after activities had been completed. While GM teaching was predominantly teacher-led, opportunities for unguided practice and play were more frequent outdoors. We conclude that Singapore preschool educators need support to better enact the guidelines of the GM curriculum framework. The study enriches the thin classroom-based international literature on GM education.     

Dual identities: organizational negotiation in STEM-focused Catholic schools

In the last decade, STEM-focused schools have opened their doors nationally in the hope of meeting students’ contemporary educational needs. Despite the growth of these STEM-focused institutions, minimal research exists that follows how schools make a transition toward a STEM focus and what organizational structures are most conducive to a successful transition. The adoption of a STEM focus has clear implications for a school’s organizational identity. For Catholic schools, the negotiation of a new STEM focus is especially complex, as Catholic schools have been shown to generally possess a distinct religious and cultural organizational identity. The adoption of a second, STEM-focused identity raises questions about whether and how these identities can coexist. Framed by perspectives on organizational identity and existing conceptualizations of the cultural and religious hallmarks of Catholic schools, this study utilizes a multiple-case study design to explore the organizational transition of four Catholic K-8 institutions to Catholic STEM-focused schools. These cases demonstrate the particular challenges of negotiating multiple organizational identities. While variation existed in how the four schools accommodated these identities, the most promising environments for successful transition drew upon an aggregative model of identity negotiation, that is, when schools attended to both identities, but ensured that the original Catholic identity of the school remained foundational to all decisions. The least successful identity negotiations occurred when there was a lack of common understanding about what comprised a STEM-focused school, leading to minimal buy-in from stakeholders or when a school sought to make the transition for recruitment or marketing rather than mission-driven reasons. Discussion of the more successful identity aggregation provides a framework for schools within and beyond the religious sector that desire to adopt an additional STEM-focused identity.     

Cognitive skill performance among young children living in poverty: Risk, change, and the promotive effects of Early Head Start

The purposes of the present study were to examine associations between risk factors and the cognitive performance from one to three years of age of children living in poverty, and to investigate the protective and/or promotive effects of EHS on children's cognitive skill performance. Analyses were conducted using data from the Early Head Start (EHS) Research and Evaluation Project, a prospective study of 3001 children and families living in poverty. There were four main findings. First, children's cognitive skill scores decreased significantly from one to three years of age in comparison to national norms. Second, children whose families were on government assistance, children whose mothers had less than a high school education, children who received lower levels of cognitive and language stimulation at home, and children who had higher levels of negative emotionality evidenced more rapid rates of decline. Third, children in families who received government assistance, children whose parents were unemployed, and children whose mothers had less than a high school education had lower cognitive skill scores at three years of age. Fourth, children who were enrolled in Early Head Start (EHS) had higher cognitive skill scores at three years of age than their peers who were not in EHS. Implications for policy and early education are discussed.

Strategies for Assessing Classroom Teaching: Examining Administrator Thinking as Validity Evidence

All 50 states use observations to evaluate practicing teachers, but we know little about how administrators actually reason when they use those observation protocols. Drawing on think-aloud and stimulated recall data, this study describes the types of strategies and warrants practicing administrators used when rating with their district’s observation protocol. Administrators in a large urban district used an observation protocol aligned to Danielson’s Framework for Teaching to rate a brief lesson clip. Administrators’ thinking was recorded, clarified, and inductively coded. Findings suggest administrator thinking and justification is complex even for short lengths of instruction. Administrators used a range of reasoning strategies, many of which were not sanctioned by their training. Exploratory analyses suggest strategy use was not related to the accuracy of ratings. Implications for the validity of teacher observation scores in high-stakes settings are considered.     

Predictors of English spelling in bilingual and monolingual children in Grade 1: the case of Cantonese and Tagalog

In order to examine the effect of the home language on the spelling development in English in children who are learning English as a second language (ESL learners), it is best to directly compare groups of ESL learners from various home language backgrounds. This study compared the oral language, phonological awareness, reading, and spelling performance of Tagalog–English bilingual, Cantonese–English bilingual, and monolingual English-speaking children in Grade 1. The bilingual children had lower scores than the monolinguals on measures of oral proficiency, but demonstrated similar or better performance on most phonological awareness, reading, and spelling tasks after controlling for vocabulary size in English. A series of moderated regression analysis revealed that although phonological awareness was associated with English spelling performance regardless of language background, the associations between specific spelling tasks and related underlying skills seemed to differ across language groups.
