Lessons In Persistence: Investigating The Challenges Faced By Preservice Teachers In Teaching Coding And Computational Thinking In An Unfamiliar Context, Vinesh Chandra, Margaret Lloyd

Australian Journal of Teacher Education

An ongoing problem for teacher education institutions is bridging the gap between theory and practice and offering authentic experiences to challenge preservice teachers’ pedagogical decision-making. Preservice practicums simulate teaching and can, at best, offer controlled experiences in familiar settings. This restricts the opportunities for preservice teachers to develop confidence in their own pedagogical decision-making and to adapt curriculum to meet unknown or unforeseen conditions. This paper describes, through a small-scale qualitative case study, a teaching experience in an unfamiliar setting, the persistent actions taken to respond to a specific context and the impact this had on preservice teacher knowledge and …

Primary Science Teachers’ Self-Efficacy And Outcome Expectancy: A Case Study, Gillian Ward, Helen Dixon, Helen Withy

Australian Journal of Teacher Education

Self-efficacious teachers are critical in the development of students’ positive attitudes towards science and scientific literacy yet to date little attention has been given to studies of experienced teachers of primary science and development of their self-efficacy (SE) beliefs. The aim of this study was to explore how two experienced teachers of primary science built their SE beliefs and outcome expectancy. Bandura’s (1977) SE framework provided the conceptual lens to understand participants’ experiences and beliefs. Findings suggest that teachers’ SE beliefs had developed over time, creating a foundation for a strong expectancy outcome. Each of the sources of influence made …

Anatomy Of A Peace Educator: Her Work And Workplace, Gulistan Gursel-Bilgin, David Flinders

Australian Journal of Teacher Education

This article reports a case study that examined the peace education practice of a 5th and 6th grade teacher at an independent, non-profit school in the Mid-western United States. The study used Paulo Freire’s (1970) conception of dialogue as its conceptual framework. After describing the study’s context and methods, we present data focusing on the teacher’s background and development as a peace educator, her teaching practices, and her relationships with her students, school and local community. We discuss Michelle’s interdisciplinary approach to peace education linked with her personal background and her use of dialogue as dynamic, fluid, and relational. Our …

Investigating The Different Dimensions Of Preservice Mathematics Teachers’ Understanding – The Case Of Factorisation, Olivia Fitzmaurice, Jacqueline Hayes

Australian Journal of Teacher Education

This paper reports on a study designed to investigate preservice teachers’ understanding of factorisation, a topic not explicitly taught within their teacher education programme, but one they will be required to teach when they graduate. We query if the knowledge they bring from secondary school, prepares them sufficiently to teach their future students for understanding. 83 preservice secondary school mathematics teachers’ procedural and conceptual understanding of quadratic factorisation were assessed using Usiskin’s Framework for understanding mathematics (2012) which identifies several dimensions of understanding. The study provides evidence that the preservice mathematics teachers have a strong procedural understanding, and while some …

Implicit Theories Of Learning As Reflected In One Upper Elementary Teacher's Talk, Laura May, Diane Truscott, R. D. Fremeau

Australian Journal of Teacher Education

Strong empirical evidence exists indicating language can influence students’ beliefs about ability. Professional literature for teachers offers practical advice on how to adjust their classroom-based talk to support student achievement by orienting students toward an incremental theory of ability. Yet, little empirical work has been done to investigate how teacher talk plays out moment-to-moment within the classroom context. This study reports on a qualitative analysis of one upper elementary teacher's talk with regard to implicit theories of learning. Findings suggest teacher talk is dynamic and overlapping, operating along a continuum from entity-oriented talk to incremental-oriented talk across varied classroom situations. …

Development Of Historical Thought In Primary Education: Analysis Of An Intervention In Colombian Schools, Nancy Palacios Mena, Paula Garcia, María Lucia Mosquera, Natalia Alarcón

Australian Journal of Teacher Education

The main goal of this study was to analyze the development of historical thinking abilities in two groups of fourth graders in Colombian schools. The study consisted of the design, implementation, and evaluation of a three-month pedagogical intervention. After an initial assessment, nine learning activities were implemented. An Intervention Group (IG) received the intervention, while a Control Group (CG) served as a comparison. The assessment comprised three main areas (Historical Sources, Narratives, and Change and Continuity).

The results of the intervention indicated that the IG performed better than the CG in the assessment. Introducing concepts that favor historical thinking development …

The Efficacy Of A Computer Program For Increasing Phonemic Awareness And Decoding Skills In A Primary School Setting For Children With Reading Difficulties, Tiffany Winn, Julia Miller, Willem Van Steenbrugge

Australian Journal of Teacher Education

This paper addresses a gap in research regarding the efficacy of software programs to help children with reading difficulties. Forty-two children aged 5-13 years identified as poor readers participated in a study over twelve weeks using ReadingDoctor, a software program targeting phonemic awareness, orthographic-phonemic mappings, decoding ability and sight word recognition. Measures were taken using the Sutherland Phonological Awareness Test - Revised (SPAT-R), the Test of Word Reading Efficiency (TOWRE), and the graphemes and decoding subtests of the Phonological Awareness Test 2 (PAT-2). A quasi-experimental one group study with three multiple baseline measures was used. The dependent variables/measures were assessed …

Increasing College Entrance Testing Vocabulary For Secondary Students With High-Incidence Disabilities, Cynthia C. Massey, Margarett E. Shippen, Margaret M. Flores, Cindy Head

Georgia Educational Researcher

This study investigated the effects of an instructional technology device, specifically, a computer-based graphic organizer, called the Real-World Connections Vocabulary graphic organizer (Ellis, 2015), on vocabulary acquisition for college entrance testing skills of students with high-incidence disabilities. Although graphic organizers have been studied since the 1960’s, there is very little research regarding the effectiveness of computer-based graphic organizers when used with high school students with mild disabilities, and their benefit acquiring college entrance exam vocabulary knowledge, namely, the ACT exam. By means of a single-subject, multiple probe across participants design, this study demonstrated that a functional relation did exist between …

All Peer-Reviewed Publications

Edible insects are receiving attention as a protein source in the food and feed sector. However, successful commercialisation requires mass production matched with appropriate processing and storage techniques. The quality of dried and pulverised black soldier fly larvae stored in woven polypropylene (PP) sacks, polyethylene (PE) bags and plastic containers with screw lid (PL) in ambient and refrigerated environments was monitored over six months. Chemical indicators (oxidation, fatty acid profile), microbiological parameters (total viable counts, yeast and moulds, Enterobacteriaceae, presumptive coliforms, Salmonella) and colour change were examined. Temperature and relative humidity of the storage environments were monitored. In the ambient …

Restricting Pesticides On A Traditional Crop: The Example Of Khat (Catha Edulis) And The Njuri Ncheke Of Meru, Kenya, James S. Krueger, Daniel M. Mutyambai

All Peer-Reviewed Publications

Rampant increase and diversification of synthetic pesticides poses health, environmental, and livelihood risks especially to smallholder farmers who dominate agriculture in sub-Saharan Africa. Legal mechanisms for regulating pesticides, although important, have not fully addressed the dangers of ecological services disruptions due to accumulation of different pesticides over time. Legal mechanisms also are not well suited to developing countries because of weak monitoring and enforcement capacity. Understanding the role of other accountability mechanisms in farming, driven by norm leaders in the community, is thus of paramount importance. We investigated the effectiveness of a traditional accountability mechanism, i.e., local councils of elders …

Implementing Welfare Science: Case Studies In Evidence-Based Zoo Management, Marisa Suzanne Spain

UNF Graduate Theses and Dissertations

Animal welfare science is a field that focuses on how we can improve the lives and well-being of animals in human care. Modern welfare science has moved away from simply preventing suffering and on to promoting positive welfare states, a concept that has been coined animal “wellness”. A process called evidence-based zoo management has been implemented in many zoos as a way to promote and ensure wellness. This is the idea that husbandry and housing standards should be evaluated and tested for their efficacy using data rather than relying on traditional best practices. In this manuscript we discuss an informal …

Articles

Candida haemulonii is an emerging opportunistic pathogen resistant to most antifungal drugs currently used in clinical arena. Metal complexes containing 1,10-phenanthroline (phen) chelating ligands have well-established anti-Candida activity against different medically relevant species. This study utilized larvae of Galleria mellonella, a widely used model of in vivo infection, to examine C. haemulonii infection characteristics in response to different copper(II), manganese(II), and silver(I) chelates containing phen, which had demonstrated potent anti-C. haemulonii activity in a previous study. The results showed that C. haemulonii virulence was influenced by inoculum size and incubation temperature, and the host G. mellonella immune …

Resolving Tensions Between Disability Rights Law And Covid-19 Mask Policies, Elizabeth Pendo, Robert Gatter, Seema Mohapatra

Articles

As states reopen, an increasing number of state and local officials are requiring people to wear face masks while out of the home. Grocery stores, retail outlets, restaurants, and other businesses are also announcing their own mask policies, which may differ from public policies. Public health measures to stop the spread of the coronavirus such as wearing masks have the potential to greatly benefit millions of Americans with disabilities, who are particularly vulnerable to the impact of COVID-19. But certain disabilities may make it difficult or inadvisable to wear a mask.

Mask-wearing has become a political flashpoint, putting people with …

Resource Selection And Calving Success Of Moose In Colorado, Forest P. Hayes

Graduate Student Theses, Dissertations, & Professional Papers

Across much of North America, moose populations (Alces alces) are declining due to disease, predation, climate, and anthropogenic pressures. Despite this, populations of moose in Colorado have continued to grow. Studying successful (i.e., persistent or growing) populations of moose can facilitate the continued conservation of the species by identifying habitat features critical for moose persistence.

First, I evaluated calving success of moose in Colorado and the impact of willow habitat quality and nutrition. I then estimated the probability of female moose having a calf using repeated observations in a Bayesian occupancy model. I assigned values for dry matter …

Real-Time Evaluation Of City–University Partnerships For Sustainability And Resilience, Liliana Elizabeth Caughman, Lauren Withycombe Keeler, Fletcher Beaudoin

Institute for Sustainable Solutions Publications and Presentations

Cities face many challenges in their efforts to create more sustainable and resilient urban environments for their residents. Among these challenges is the structure of city administrations themselves. Partnerships between cities and universities are one way that cities can address some of the internal structural barriers to transformation. However, city–university partnerships do not necessarily generate transformative outcomes, and relationships between cities and universities are complicated by history, politics, and the structures the partnerships are attempting to overcome. In this paper, focus groups and trial evaluations from five city–university partnerships in three countries are used to develop a formative evaluation tool …

The Politics Of Regulatory Enforcement And Compliance: Theorizing And Operationalizing Political Influences, Jodi L. Short

Faculty Scholarship

There is broad consensus in the literature on regulatory enforcement and compliance that politics matters. However, there is little scholarly convergence on what politics is or rigorous theorization and empirical testing of how politics matters. Many enforcement and compliance studies omit political variables altogether. Among those that address political influences on regulatory outcomes, politics has been defined in myriad ways and, too often, left undefined. Even when political constructs are explicitly operationalized, the mechanisms by which they influence regulatory outcomes are thinly hypothesized or simply ignored. If politics is truly as important to enforcement and compliance outcomes as everyone in …

Eastern Equine Encephalitis virus (EEEV) is a virus found predominantly east of the Mississippi River in the United States that can be fatal to both equines and humans. The disease has previously been most prolific in states like Florida, but there has been an increase in the prevalence in other states further up north on the east coast of the United States in recent years. The purpose of this research is to use the ecological niche modelling program Maxent to model EEEV habitat suitability probability. This research utilized data of fatality incidence in equine hosts, versus sentinel chicken infection data, …

Optimizing Arbovirus Surveillance Using Risk Mapping And Coverage Modelling, Joni A. Downs, Mehrdad Vaziri, George Deskins, William Kellner, Kristi M. Miley, Thomas R. Unnasch

School of Geosciences Faculty and Staff Publications

Diseases carried by mosquitoes and other arthropods endanger human health globally. Though costly, surveillance efforts are vital for disease control and prevention This paper describes an approach for strategically configuring targeted disease surveillance sites across a study area. The methodology combines risk index mapping and spatial optimization modelling. The risk index is used to identify demand for surveillance, and the maximum covering location problem is used to select a specified number of candidate surveillance sites that covers the maximum amount of risk. The approach is demonstrated using a case study where optimal locations for sentinel surveillance sites are selected for …
