Facilitating change in undergraduate STEM instructional practices: An analytic review of the literature

This article reviews current scholarship about how to promote change in instructional practices used in undergraduate science, technology, engineering, and mathematics (STEM) courses. The review is based on 191 conceptual and empirical journal articles published between 1995 and 2008. Four broad categories of change strategies were developed to capture core differences within this body of literature: disseminating curriculum and pedagogy, developing reflective teachers, enacting policy, and developing shared vision. STEM education researchers largely write about change in terms of disseminating curriculum and pedagogy. Faculty development researchers largely write about change in terms of developing reflective teachers. Higher education researchers largely write about change in terms of enacting policy. New work often does not build on prior empirical or theoretical work. Although most articles claim success of the change strategy studied, evidence presented to support these claims is typically not strong. For example, only 21% of articles that studied implementation of a change strategy were categorized as presenting strong evidence to support claims of success or failure of the strategy. These analyses suggest that the state of change strategies and the study of change strategies are weak, and that research communities that study and enact change are largely isolated from one‐another. In spite of the weak state of the literature, some conclusions related to the design of change strategies can be drawn from this review. Two commonly used change strategies are clearly not effective: developing and testing “best practice” curricular materials and then making these materials available to other faculty and “top‐down” policy‐making meant to influence instructional practices. Effective change strategies: are aligned with or seek to change the beliefs of the individuals involved; involve long‐term interventions, lasting at least one semester; require understanding a college or university as a complex system and designing a strategy that is compatible with this system. © 2011 Wiley Periodicals, Inc.

The Cognitive Neuroscience of the Teacher–Student Interaction

Pedagogy is the science and art of teaching. Each generation needs to explore the history, theory, and practice of the teacher–student interaction. Here we pave the path to develop a science that explores the cognitive and physiological processes involved in the human capacity to communicate knowledge through teaching. We review examples from our previous work in this research area and discuss a path to reveal the cognitive and cerebral mechanisms by which we teach, unfolding a complex operation such as teaching in its constituents and components.     

Effects of family violence on psychopathology symptoms in children previously exposed to maltreatment

Although many studies suggest that family violence is associated with child psychopathology, multiple features of the home environment might account for this association, such as poverty and caregiver psychopathology. Studies are needed examining how change in psychopathology symptoms is affected by home violence, controlling for children's own developmental symptom histories and other predictors of psychopathology. This study used latent difference score structural equation modeling to test if witnessing home violence and/or experiencing harsh physical discipline predicted changes in psychopathology symptoms among 2,925 youth aged 5-16 years previously exposed to violence. Results demonstrated that harsh physical discipline predicted child-specific changes in externalizing symptoms, whereas witnessing violence predicted child-specific changes in internalizing symptoms across time. Implications for research and policy are discussed.

‘Out of the loop’: early childhood educators gaining confidence with unfamiliar policy discourse

It has been seven years since the Early Years Learning Framework (EYLF) was introduced in Australia and four years since the National Quality Standard (NQS) was implemented. To gain insight into how educators are understanding practice in the Australian early childhood and care context, the study draws on a praxeological frame where educators have the opportunity to inquire and critically reflect on practice in a supported research environment. Data were analysed using critical discourse analysis, enabling a close examination of participant reflections and understandings about practice. Findings reveal that educators are confident when describing their teaching using familiar educational discourse, whereas educators were apprehensive when confronted with new and unfamiliar concepts. The third finding illustrates the ways educators gain confidence with unfamiliar policy discourse. The study’s findings add to limited empirical evidence about how early childhood educators understand key concepts introduced by the EYLF and NQS.     

Preschoolers' Ability to Distinguish Living Kinds as a Function of Regrowth

In order to acquire a theory of biology, children must acquire knowledge about living kinds. Although many studies have shown that preschool children do not accurately classify living kinds and do not use appropriate properties when asked to decide whether something is a living kind, recent work has shown that 3- and 4-year-olds do know something about biological growth. The ability of kinds to heal through regrowth was used in this paper as a measure of children's implicit understanding that plants and animals can be grouped together. In 3 experiments, children were told that animals, plants, and artifacts had been damaged and were asked whether the objects could heal through regorwth and whether a person could mend them. In all studies, children were sensitive to ontological kind, 4-year-olds realized that both plants and animals can regrow but that artifacts must be fixed by human intervention. 3-year-olds were less knowledgeable but did realize that artifacts cannot regrow. Overall, children showed some biological knowledge, implicity grouping plants and animals together and differentiating them from artifacts.     

Conflict Resolution Patterns of Preschool Children With and Without Developmental Delays in Heterogeneous Playgroups

The conflict resolution patterns of preschool-age mildly developmentally delayed children were compared to those of older and younger groups of typically developing children matched on the basis of chronological age or developmental level. Children participated in short-term heterogeneous playgroups consisting of representatives from all three developmental status groups. Naturally occurring conflicts with peers in the form of extended directive episodes were assessed in terms of their frequency, purpose, strategies, and the way conflicts were resolved. Results revealed that mildly delayed children exhibit a more negative and less adaptive interaction style, even in comparison to typically developing children similar in developmental level. Special problems were apparent when younger typically developing and mildly delayed children engaged in conflict episodes, whereas typically developing older children were able to adjust and interact appropriately irrespective of their companions' developmental status. In addition, typically developing older children elicited a pattern in which other children were less demanding and negative, but more responsive, positive, and adaptive. The implications of developmental differences between younger and older typically developing children and the unique problems in conflict situations were discussed.     

Establishing a Family Literacy Program with a Focus on Interactive Reading: The Role of Research and Accountability

Family literacy programs abound today, and many try to be all things to all participating families. Funding has eroded for programs of long length and shorter length programs need a specific focus to aim for a modicum of success. This article provides an overview of the importance of interactive reading for children’s future success in school, providing clear reasons for having it as a program focus. Specific research-based interactive reading behaviors which act as program objectives and a linked interactive reading assessment for accountability purposes are described. Methods of serving and recruiting diverse families are also explored. An example of a program is provided to demonstrate how to design a family literacy program of manageable length that leads to measurable gains in joint reading behaviors.     

Scoping review: The use of augmented reality in clinical anatomical education and its assessment tools

The purpose of this review was to identify the different augmented reality (AR) modalities used to teach anatomy to students, health professional trainees, and surgeons, and to examine the assessment tools used to evaluate the performance of various AR modalities. A scoping review of four databases was performed using variations of: (1) AR, (2) medical or anatomical teaching/education/training, and (3) anatomy or radiology or cadaver. Scientific articles were identified and screened for the inclusion and exclusion criteria as per Preferred Reporting Items for Systematic Reviews and Meta-Analyses with extension for scoping reviews guidelines. Virtual reality was an exclusion criterion. From this scoping review, data were extracted from a total of 54 articles and the following four AR modalities were identified: head-mounted display, projection, instrument and screen, and mobile device. The usability, feasibility, and acceptability of these AR modalities were evaluated using a variety of quantitative and qualitative assessment tools. Within more recent years of AR integration into anatomy education, the assessment of visuospatial ability, cognitive load, time on task, and increasing academic achievement outcomes are variables of interest, which continue to warrant more exploration. Sufficiently powered studies using validated assessment tools must be conducted to better understand the role of AR in anatomical education.     

‘I feel like I can do it now’: preservice teacher efficacy in a co-teaching community of practice

Teacher efficacy, or teachers’ feelings about their abilities in the classroom, remains a major component of educational research. We know that despite participating in shared or similar experiences, some preservice teachers (PSTs) develop feelings of teacher efficacy and some do not. Yet, in-depth examinations into the specific practices of successful host schools are scarce in the deep field of teacher efficacy research. We examine the deliberate actions of one Midwestern elementary school to establish a climate and co-teaching process that deliberately seeks to foster PST success and feelings of confidence in the classroom. We also discuss implications for teacher education.
