Knowledge dissemination and use in science and mathematics education: A literature review

A synthesis of the literature on knowledge dissemination and use in education, notably in science and mathematics, is presented. Perspectives have changed in the ways in which knowledge and products are seen to reach potential users. From the top-down, linear models, we have come closer to bottom-up approaches and to the crucial role of linking agents. At present, the most influential approach is a constructivist one, whereby research and other kinds of specialized knowledge is exchanged between researchers and professionals in a mutually constructed social context. While there is still debate over the best predictors of successful knowledge use, the scope of the field has been considerably enlarged by including users' perspectives. To some extent then, specialists in this field are now working in a new paradigm.Prepared for the Directorate of Education and Human Resources, Division of Research, Evaluation and Dissemination, National Science Foundation by The Network, May 1993.     

Sense of Belonging as a Predictor of Intentions to Persist Among African American and White First-Year College Students

This study investigates the role of students’ sense of belonging to their university in college student retention. Using individual growth curve modeling, we examined (a) whether sense of belonging predicts intentions to persist, and (b) the effects of an intervention designed to enhance students’ sense of belonging. African American and white first-year students completed surveys three times throughout the academic year. Students were randomly assigned to a group that received an intervention to enhance students’ sense of belonging or to one of two control groups. Sense of belonging was found to predict intentions to persist, controlling for background variables and other predictors of persistence. Overall, sense of belonging and intentions to persist declined over the academic year. However, the decline in sense of belonging was smaller for students in the intervention group. Implications for the development of college retention programs and for existing models of student persistence are discussed.     

Student teachers’ prior experiences of history,geography and science: initial findings of an all-Ireland survey1

Research into student teachers’ perceptions, attitudes and prior experiences of learning suggests that these experiences can exert an influence on practice which can be relatively undisturbed by their initial teacher education. This article is based on the initial findings of an all-Ireland survey of all first-year students on B.Ed. courses in colleges in Northern Ireland and in the Republic of Ireland. The survey is the first stage in a longitudinal study which will follow the same cohort of students for the duration of their initial teacher education, seeking to map and track the development of their ideas about teaching and learning in primary history, geography and science. Based on an analysis of the quantitative data in the entry questionnaire, the initial findings suggest that subject knowledge remains a problematic issue in initial teacher education and that both location and gender interact with knowledge, attitudes and subject area to produce a complex and challenging context for teacher educators in history, geography and science education.     

Assessment of preschool classroom practices: Application of Q-sort methodology

This paper reports on the application of Q-sort methodology to the development of the Preschool Classroom Practices (PCP) Q-sort. The PCP Q-sort was tested in a sample of 66 preschool teachers and assistants. Results demonstrated the existence of a 2-cluster structure within the Q-sort, comprised of Cognitive Development Activities and Socioemotional Development Activities. Specific properties of the PCP Q-sort, including cluster means, demonstrated consistency across both samples and time. Preschool teachers reported engaging in significantly more Socioemotional Development Activities than Cognitive Development Activities. Relationships to classroom observational measures are presented. Application of the PCP Q-sort as a measure of classroom practices and implications for preschool curriculum are discussed.     

Talking about maths

This article looks at why talk is important for young children learning mathematics, how talk fosters mathematical understanding and the importance of having something to talk about by relating maths to real situations. It then looks at the revealing comments of some four and five year old children talking about simple number activities linked to a favourite rhyming story song they had been singing.     

‘Our garden is colour blind,inclusive and warm’: reflections on green school grounds and social inclusion

In the interest of enhancing children's environments, communities around the world are ‘greening’ school grounds, replacing asphalt and manicured grass with a diversity of design elements such as trees, shrubs, gardens, water features, artwork and gathering areas. Despite a growing body of research from a number of disciplines exploring the potential of these spaces, very little is known about the ways they can promote social inclusion with respect to gender, class, race and ability. This paper explores the relationship between school ground greening and social inclusion in a Canadian public school board where approximately 20% of more than 500 schools have begun the greening process. A mixed methods approach was used: (1) 149 questionnaires were completed by administrators, teachers and parents associated with 45 school ground greening initiatives; and (2) 21 follow‐up interviews were conducted with administrators, teachers and parents at five schools across a range of socio‐economic statuses. The study revealed that green school grounds are more inclusive of people who may feel isolated on the basis of gender, class, race and ability, suggesting that these spaces promote, in a very broad sense, social inclusion.     

Autocontingencies: Factors underlying control of operant baselines by compound tone/shock/no-shock contingencies

Previous research has shown that postshock acceleration of baseline responding, which normally results from exposure to a shock/no-shock autocontingency, is eliminated when a suppressive tone-shock contingency is simultaneously presented (Davis, Memmott, & Hurwitz, 1975). Three experiments were performed to explore this inability to produce joint suppressive/ accelerative control by compound tone-shock and shock/no-shock contingencies. Progressively degrading the tone-shock contingency in Experiment 1 maintained conditioned suppression and resulted in asymptotic levels of postshock acceleration in all degraded groups. Evidence for accelerative control by the autocontingency was also recorded in a control group that received a totally reliable tone-shock relation. Experiments 2 and 3 pursued this latter finding, which is in direct conflict with our earlier results. The appearance of joint suppressive/ accelerative control by tone-shock and shock/no-shock contingencies appears to be related to the number of shock trials given per session; moreover, relatively small differences in trial density (e.g., three trials per 22.5 min vs. three trials per 30 min) are critical to establishing joint autocontingency control. The importance of shock rate is discussed with regard to the relative waiting time hypothesis, an alternative model of Pavlovian control, as well as to previously reported conditioning failures involving compound suppressive/accelerative procedures.     

RFID systems in libraries: An empirical examination of factors affecting system use and user satisfaction

Library operation and management requires the performance of a number of repetitive, painstaking, labour- and time-intensive activities. Hence, in order to increase efficiency and effectiveness, many libraries are moving towards automation of the majority of their activities. Libraries are deploying Radio Frequency Identification (RFID) technology as a substitute for barcode systems for item identification and tracking, and this ultimately enables the automation of the majority of their processes. It is apparent from the available literature that research on RFID-related issues is largely concentrated on technical, organizational and implementation aspects, and less attention has been paid to understanding the use and user-satisfaction aspects. Therefore, this article aims to understand factors affecting the use of RFID systems and user satisfaction in a library context by empirically testing relevant constructs from DeLone and McLean's IS Success Model. A questionnaire-based survey was employed to collect data from a total of 181 respondents, who were all active users of an RFID-based library system. The findings from this study suggest that factors like system quality, use and user satisfaction positively influence consumer attitudes towards RFID-enabled services. The concluding section outlines salient points and briefly describes the associated limitations of this research, along with suggestions for future research directions.     

Counterspaces for women of color in STEM higher education: Marginal and central spaces for persistence and success

Counterspaces in science, technology, engineering, and mathematics (STEM) are often considered “safe spaces” at the margins for groups outside the mainstream of STEM education. The prevailing culture and structural manifestations in STEM have traditionally privileged norms of success that favor competitive, individualistic, and solitary practices—norms associated with White male scientists. This privilege extends to structures that govern learning and mark progress in STEM education that have marginalized groups that do not reflect the gender, race, or ethnicity conventionally associated with STEM mainstream success, thus necessitating spaces in which the effects of marginalization may be countered. Women of color is one such marginalized group. This article explores the struggles of women of color that threaten their persistence in STEM education and how those struggles lead them to search out or create counterspaces. It also examines the ways that counterspaces operate for women of color in STEM higher education, particularly how they function as havens from isolation and microaggressions. Using a framework of Critical Race Theory (CRT) and intersectionality theory and drawing on interview data from 39 women of color about their STEM higher education experiences, we describe five ways in which counterspaces operate: in peer‐to‐peer relationships; mentoring relationships; national STEM diversity conferences; STEM and non‐STEM campus student groups; and STEM departments. Whereas most research has discussed counterspaces as racially or ethnically homogeneous social groups of peers at the margins, our research found that counterspaces vary in terms of the race/ethnicity, gender, and power levels of participants. We found that counterspaces can be physical settings, as well as conceptual and ideological. Additionally, we identified counterspaces both at the margins and at the center of STEM departments. Thus, our research expands the existing understanding of the types and functions of counterspaces and broadens the definition of what locations can be and should be considered counterspaces. © 2017 The Authors.
