The Use of an Evidence Based Practice Approach to Promote Active Student Engagement and Life - Long Learning in an Online Graduate Certificate
Authors: O'Neill Emma
Published: April 2017

Educational research has realigned away from the delivery of information towards the enhancement of learning and construction of knowledge (Edmondson, 2001). The availability of information is no longer the limiting factor; the ability to process and rationalise the vast amount of information available is now far more important. As suggested by Alvin Toffler, “The illiterate of the 21st century will not be those who can­not read and write, but those who cannot learn, unlearn and re-learn.” Hence, it is important to consider ways to equip students with the skills for critical appraisal and life-long learning. Teaching strategies that engender a deep approach to learning by promoting active student engagement are key to these aims.

The recently launched Graduate Certificate in Small Animal Medicine is aimed at practicing veterinarians wishing to improve their knowledge and skills more specifically in this area. This post-graduate course re­quires students to develop and demonstrate higher order learning skills during the course of their studies. This project explores the use of an Evidence-Based Practice approach as a central theme for promoting active engagement and the development of higher order learning skills within this graduate programme. The overall aim being to promote a change in the practitioners’ approach to case management rather than just to present them with large amounts of factual information.

The learning approach taken by students during their studies is profoundly influenced by course design and assessment strategy (Biggs and Collins, 1982). Hence care needs to be taken to align these ap­proaches with the desired outcomes. The students were initially introduced to the five-step approach to evidence-based practice, as recommended in the Sicily statement on effective teaching of evi­dence-based practice (Dawes et al 2005). Over the course of the programme they were encouraged to apply and build on this process in the clinical setting and to present their work on discussion boards for peer review and discussion. They developed critically appraised topic (CAT) reviews working both indi­vidually and in groups, and as their final capstone assessment presented a case report with an integrat­ed CAT to defend one aspect of their case management. The preliminary findings of this work are that students valued and engaged extremely well with the overall process, which promoted active, structured discussion and a visible progression of their appraisal skills over the course of the one-year programme. The generation of a learning resource for later reference was an added benefit to this approach.

Published: April 2017

Purpose: Three aims were addressed: (a) Evaluate properties of the items comprising the Life Changes in Epilepsy Scale-Pilot (LCES-P), (b) use item analysis to optimize the scale, (c) evaluate construct and criterion-related validity of the optimized LCES. Methods: The LCES-P was administered to 174 adults with epilepsy. Item analysis and exploratory factor analysis were performed. Internal consistency reliability, construct validity, and criterion-related validity were evaluated. Results: 17 items were retained in the optimized LCES. Internal consistency reliability was supported. Path analysis was used to evaluate construct validity. Criterion-related validity was supported by correlations with the Medical Outcomes SF-36 Survey (SF-36) General Health subscale and a criterion variable. Conclusions: The optimized version of the LCES can serve as a valuable outcome measure in clinical and research environments.

Published: April 2017

Introduction. The project “Little Physician” has been run for over four years as a joint project of the Poznań University of Medical Sciences and the Polish Academy of Kids. It is an innovative undertaking in the international educational market, where young ‘scientists’ aged from 6 to 12 contribute to the classes and pursue their research interest in the broadly understood field of natural science. Aim. The aim of this research was to probe the opinions of the teachers participating in the “Little Physician” initiative. Material and Methods. The research was conducted on the population of 32 teachers. The applied technique was an interview based on an original questionnaire consisted of respondent`s particulars and 7 questions evaluating the usefulness, quality and thematic range of the classes, as well as the lecturers’ competencies and organisation of the classes. Results. The usefulness of the project was positively evaluated by all the interviewees (81% rated it as “very good”, 19% thought it was “good”). As many as 75% of the respondents decided that the thematic range of the lectures was “very good”. An even higher percentage assessed very positively the competencies of the adults giving lectures, the coordinators of the classes, the lecture halls and the manner in which classes were conducted. Conclusions. The project is very highly evaluated by the teachers supervising the participating children. The high assessment stems from the high competencies of the coordinators and lecturers participating in the classes, an accurate choice of issue or subjects discussed.

Authors: PINTO Luis Gabriel Quintero , PEZZATO Luiz Edivaldo , GAMBOA Blanca Stella Pardo , ARAUJO Daniel de Magalhães
Published: April 2017

A digestibilidade aparente dos nutrientes de ingredientes proteicos e fosfatos inorgí­¢nicos foi comparada em três diferentes fases de desenvolvimento da tilápia-do-nilo. Os ingredientes testados foram farinha de peixe, farinha de ví­­sceras de aves, farinha de carne e ossos, glúten de milho, farelo de soja, farelo de algodão, fosfato monobicálcico, fosfato bicálcico, fosfato monopotássico e ácido fosfórico. Os coeficientes de digestibilidade aparente (CDAs) de matéria seca, proteí­­na, energia, P, Ca e Mg foram determinados com peixes de 25 g, 250 g e 500 g. Concluiu-se que a capacidade da tilápia-do-nilo de digerir os alimentos e absorver os nutrientes é dependente do peso corporal e das caracterí­­sticas do alimento avaliado. Houve tendência de melhor aproveitamento de nutrientes dos alimentos de origem animal e das fontes inorgí­¢nicas pelos peixes de 25 g. Os peixes de 250 g e 500 g mostraram melhor aproveitamento dos nutrientes das fontes proteicas de origem vegetal quando comparados aos peixes de 25 g.

Published: April 2017

A sardinha-verdadeira (Sardinella brasiliensis) é o principal recurso pesqueiro do Brasil, sustentando diretamente a indústria de enlatados, como matéria prima, e indiretamente a pesca dos tuní­­deos, pois juvenis são utilizados como isca-viva. A UFSC, através do Projeto Isca-Viva, vem desenvolvendo técnicas de produção de sardinha-verdadeira em cativeiro com vistas ao uso sustentável do recurso, entretanto não existem informações sobre a toxicidade dos compostos nitrogenados no cultivo desta espécie. O objetivo deste estudo foi estimar a toxicidade aguda de amônia (NH3-N) em juvenis de sardinha-verdadeira. Grupos de cinco peixes (1,04 Â± 0,20 g) foram expostos a cinco concentrações de NH3-N (0,60 a 1,47 mg L-1) durante 96 h, mais um grupo controle em triplicata. Os testes foram conduzidos em um sistema semiestático com renovação diária total dos meios experimentais. Os resultados foram apresentados como dados de mortalidade, registrados nas diferentes concentrações testadas, utilizando o software Trimmed Spearman Karber Method. A concentração letal (LC50) após 96 h de exposição a NH3-N foi estimada em 0,74 (0,61-0,90) mg L-1. Os resultados indicam que juvenis de sardinha-verdadeira são relativamente sensí­­veis í­Â  amônia em relação a outros peixes marinhos e que atenção especial deve ser dada a este composto em sistemas de cultivo.

Published: April 2017

Avaliou-se a influência dos ní­­veis de grãos secos de destilaria com solúveis (DDGS) no desempenho reprodutivo de lambaris. Foram elaboradas dietas contendo 0%, 10%, 20% e 30% de DDGS. Os peixes foram estocados durante 150 dias em 16 tanques com biofiltro, sistema individual de aquecimento e recirculação de água, na densidade de 0,3 peixe L-1. Foram determinados: fator de condição corporal, í­­ndice gonadossomático, volume dos ovos, fertilidade inicial, fertilidade inicial relativa, taxa de fertilidade, í­­ndice de desova, fertilidade final, fertilidade final relativa, taxa de eclosão e de sobrevivência das larvas, dií­¢metro dos ovos e do vitelo e comprimento das larvas. Realizaram-se também histologia das gônadas das fêmeas e dos machos e avaliação do sêmen. Os dados foram submetidos í­Â  análise de varií­¢ncia, regressão e teste de tendência. A adição de DDGS nas dietas afetou a fertilidade inicial nas fêmeas, o peso, o comprimento total e o padrão dos machos (P<0,05). Para as outras variáveis não foram observadas diferenças (P>0,05). Não foram evidenciadas diferenças entre as estruturas morfológicas dos ovários, mas os testí­­culos dos peixes alimentados com dieta de 30% de DDGS apresentaram células espermáticas em abundí­¢ncia. O DDGS pode ser usado como alternativa proteica, sem gerar prejuí­­zos ao desempenho reprodutivo.

Authors: RIBEIRO Mayara da Cruz , MORON Sandro Estevan , LOPES Jane Mello
Published: April 2017

O objetivo foi avaliar os efeitos de diferentes concentrações de amônia não ionizada (zero; 0,15; 0,30; 0,50; 1,00 mg L-1 NH3) na histologia e morfologia das brí­¢nquias e fí­­gado de juvenis de Bryconops caudomaculatus. Após 96 horas de exposição, os peixes foram anestesiados e submetidos í­Â  necropsia para coleta de brí­¢nquias e fí­­gado, que foram incluí­­dos em parafina. Alterações morfológicas nas lamelas secundárias das brí­¢nquias foram observadas em concentrações a partir de 0,15 mg L-1, como hiperplasia, hipertrofia, deslocamento epitelial, fusão lamelar, edema, aneurisma lamelar com ruptura do epitélio e aumento na largura das lamelas. O fí­­gado apresentou alterações histológicas (congestão nos capilares, processos inflamatórios e pigmentação endógena) na presença de 0,30 mg L-1 de NH3, que comprometeram as funções vitais, o metabolismo, processos de respiração, desintoxicação do organismo, hematopoese e provavelmente a osmorregulação. Os resultados sugerem que as alterações nas brí­¢nquias e fí­­gado podem ser usadas para monitorar o desempenho de peixes em cultivo intensivo.

O objetivo deste trabalho foi avaliar a eficiência do hidrolisado do resí­­duo de sardinha como atrativo alimentar para o jundiá (Rhamdia quelen), comparando sua escolha em relação í­Â  de outros atrativos. Foram realizados dois experimentos: no primeiro, as substí­¢ncias foram inoculadas diretamente na água do aquário e, no segundo, incluí­­das em péletes de ágar. No experimento 1, a inoculação das substí­¢ncias (hidrolisado de sardinha, extrato de músculo de tilápia e água destilada) na água não afetou a distribuição dos peixes entre os compartimentos. No experimento 2, a maior proporção dos peixes entrou primeiro no compartimento contendo os atrativos (hidrolisado de sardinha, extrato de músculo de tilápia e ácido glutí­¢mico). Não foi encontrada diferença na distribuição dos peixes entre os compartimentos quando dois atrativos foram avaliados simultaneamente. Os péletes contendo extrato de músculo foram ingeridos primeiro e em maior quantidade em relação aos que continham água destilada. A avaliação dos atrativos em péletes mostrou que o hidrolisado de resí­­duo de sardinha é eficiente como atrativo alimentar para o jundiá. Não houve diferença na escolha em relação aos outros atrativos. A inclusão das substí­¢ncias em péletes é uma metodologia válida na avaliação de diferentes atrativos.

We used international survey data from women aged 15 to 49 years from 28 Demographic and Health Surveys (2010–2014) to examine the association between owning assets and experience of recent IPV, matching on household wealth by using multivariate probit models. Matching methods helped to account for the higher probability that women in wealthier households also have a higher likelihood of owning assets.

Results. Asset ownership of any type was negatively associated with IPV in 3 countries, positively associated in 5 countries, and had no significant relationship in 20 countries (P < .10). Disaggregation by asset type, sole or joint ownership, women’s age, and community level of women’s asset ownership similarly showed no conclusive patterns.

Conclusions. Results suggest that the relationship between women’s asset ownership and IPV is highly context specific. Additional methodologies and data are needed to identify causality, and to understand how asset ownership differs from other types of women’s economic empowerment.
Adsorption of Hg(II) from aqueous solution using functionalized hydrogel loaded with hydrous manganese dioxide particles
Authors: Yan Gong , Oliver Su Philipp
Published: April 2017

In this paper, a high performance adsorbent (hydrous manganese oxides onto acylamino and hydroxyl functionalized hydrogel) containing manganese oxide was prepared by the cross-linking polymer; the novel composite adsorbent has an excellent adsorption for Hg(II) removal. The adsorbent was characterized by scanning electron microscopy and Fourier transform infrared analysis, the hydrogel adsorbent had a typical three-dimensional network structure, and manganese oxides particles were dispersed into the channel and pores structure. The adsorption of Hg2+ in water was tested by using the adsorbent. The results show that the adsorption isotherms were fitted well with Langmuir model, and the maximum Hg2+ adsorption capacity was 0.654 mmol g−1 (131.2 mg g−1). The adsorption kinetics followed a pseudo-second-order equation, and the adsorption equilibrium can be reached in the first 120 min. The optimum pH of adsorption was determined to be 8.0. The desorption efficiency of 94% can be reached using 0.7 mol L−1 HCl as the regeneration agent. The results suggest that this material can be a promising adsorbent for Hg2+ removal in several industrial processes.
Effects of hydraulic loading rate and aeration mode on nitrogen removal and nitrogen functional gene abundances in subsurface wastewater infiltration systems
Authors: Sun Yafei , Pan Jing , Qi Shiyue , Fei Hexin
Published: April 2017

Matrix dissolved oxygen, nitrogen removal and nitrogen functional gene abundances in two artificial aeration modes, continuous aeration (CA) and intermittent aeration (IA), in subsurface wastewater infiltration systems (SWISs) under different hydraulic loading rates (HLRs) were investigated. Aeration not only successfully created aerobic conditions at 50 cm depth, but also did not change anoxic or anaerobic conditions at 80 and 110 cm depths. Meanwhile, aeration significantly enhanced chemical oxygen demand, NH4+-N, and total nitrogen (TN) removal and the enrichment of nitrogen removal functional genes (amoA, nxrA, napA, narG, nirK and qnorB) compared to the non-aerated SWIS, especially for high HLRs. IA SWIS (79.7%–85.8%) had a better performance on TN removal compared with CA SWIS (73.8%–82.2%) when the HLRs ranged from 0.06 to 0.3 m3/(m2 d). Intermittent aeration is a sensible strategy to achieve high HLR, good nitrogen removal performance and comparatively low operation cost for SWISs.

HOW WE FAILED TO PLAN FOR HABITABILITY
Authors: Lik Meng Lee , Abdullah Aldrin , Sook Fern Tan , Badarulzaman Nurwati , Hassan Ahmad Sanusi
Published: April 2017

A quality housing development should not only take into account the physical aspects of design but also be sensitive to human needs. Habitability in housing involves several components, including environmental factors, man-made designs, socio-cultural operations and psychological impacts. Elements of habitability can be observed in various concepts of residential developments including classical concepts such as the Garden City Movement and the Neighbourhood Unit. In Malaysia, the Malay Kampung and the Chinese New Village exemplify some ideal living practices relating to habitability. Both the classical and traditional concepts influenced subsequent residential developments in Malaysia such as the Jengka Project, Kampung Tersusun, Town 8, Cyberjaya and Putrajaya. However, not all residential developments succeeded in creating a quality living environment. More recent concepts such as the New Urbanism and the China Healthy Residence have placed greater emphasis in dealing with such issues. In Malaysia, legislations and policies have not adequately addressed the problems on habitability. We lack a thorough planning system, which prepares and monitors the quality of our residential development. Failures in planning policies have also created other planning issues that affect habitability, as portrayed in the case of the Rifle Range Low-cost Flats in Penang. The top-down approach in housing policy andplanning should be geared up to match the growth of community towards achieving habitability.
Cluster Analysis and Rankings of Canadian Universities: Misadventures with Rank-based Data and Implications for the Welfare of Students
Authors: Cramer Kenneth M. , Page Stewart
Published: April 2017

We present a data-based perspective concerning the Maclean’s magazine (November 17, 2003) rankings of Canadian universities, including two cluster analyses and other nonparametric analyses. These data are similar to those in recent university ranking exercises conducted by other magazines, such as U.S. News. In many cases, the cluster procedure showed that universities actually resemble and relate to each other in a manner different from their formal classification and final rank ordering by Maclean’s. Several pitfalls in ranking procedures, related to unreliable relationships among specific indices underlying the final ranks, are outlined. Comparisons are made also with the most recent student satisfaction rankings for 47 Canadian universities, published in November, 2003, by the Toronto Globe and Mail. The latter rankings do not reliably reflect the general results of the Maclean’s data. In their present format, and although they have become increasingly publicized and promoted, it remains difficult for the Maclean’s data to be consistently or empirically useful to students. Ranking exercises have unintended, though increasingly predictable, consequences, which likely bear heavily upon the intellectual and personal well being of students.
The Facets Of Job Satisfaction: A Nine-Nation Comparative Study Of Construct Equivalence
Authors: Kwantes Catherine T.
Published: April 2017

Archival data from an attitude survey of employees in a single multinational organization were used to examine the degree to which national culture affects the nature of job satisfaction. Responses from nine countries were compiled to create a benchmark against which nations could be individually compared. Factor analysis revealed four factors: Organizational Communication, Organizational Efficiency/Effectiveness, Organizational Support, and Personal Benefit. Comparisons of factor structures indicated that Organizational Communication exhibited the most construct equivalence, and Personal Benefit the least. The most satisfied employees were those from China, and the least satisfied from Brazil, consistent with previous findings that individuals in collectivistic nations report higher satisfaction. The research findings suggest that national cultural context exerts an effect on the nature of job satisfaction.
Brave New Teachers: Doing Social Justice Work in Neo-liberal Times
Authors: Pollard Barbara Anne
Published: April 2017

The authors of Brave New Teachers adopt a critical-democratic lens to analyze how neoliberal educational agendas have impacted the ability of progressive teachers to cultivate equitable and inclusive classrooms. The book is based on a longitudinal study that documents the self-reported teaching experiences of a group of teachers who graduated from the Urban Diversity Program at York University. Brave New Teachers explores how the current context of Canadian schooling has been shaped by neoliberalism. Within this paradigm, the authors thematically emphasize how the standardized testing and accountability movement, as well as the top-down imposition of curriculum standards, circumscribe the efforts of courageous teachers who work diligently on creating anti-oppressive curriculums and school environments. The tension that exists when these teachers feel pressured to conform to higher top-down authorities is documented throughout the` book.
Towards Designing an Intercultural Curriculum: A Case Study from the Atlantic Coast of Nicaragua
Authors: Daniel Patricia
Published: April 2017

One of the challenges still to be met in the 21st century is that of genuinely embracing diversity. How can education help to overcome the barriers that continue to exist between people on the basis of language, culture and gender? This case study takes the Atlantic Coast of Nicaragua as an example of a multilingual/multiethnic region and examines how the community university URACCAN is contributing to the development of interculturality. It describes participatory research that was carried out with university staff and students with the intention

of defining an intercultural curriculum and appropriate strategies for delivering such. One model used as a basis for discussions was the Model for Community Understanding from the Wales Curriculum Council, which emphasises the belonging of the individual to different communities or cultures at the same time. Factors supporting the development of an intercultural curriculum include the university’s close involvement with the ethnic communities it serves. However, ethno-linguistic power relations within the region and the country as a whole, still militate against egalitarianism within the university. The research highlights the importance of participatory pedagogy as the basis for promoting interculturality and achieving lasting social transformation.
Survival Kit or Lessons for Life? Future Directions for Preservice Teacher Education from the Perceptions of Newer Teachers
Authors: Glassford Larry , Hurley Noel
Published: April 2017

Recent literature, supported by a survey of secondary school teachers in southwestern Ontario, Canada, indicates that preservice teacher education does not adequately prepare graduating teacher candidates to thrive in a profession that is ironically, driven by change. Attempts at reform have focused on the basic aspects of the typical preservice program: foundations, curriculum methods and field experience. The results have been decidedly discouraging. Positive improvement will hinge both on a recognition by teacher-education institutions, of the inevitable compromise between short-term necessity and long-term vision, and on their willingness to implement, carefully and constructively, promising innovations such as action research and centers of pedagogy.
The Role of Multi-data Evaluations in the Site-based Management: An Examination of an Innovative Teacher Professional Growth Plan
Authors: Goddard Tim , McKinnon Margot
Published: April 2017

In this paper we present and discuss a new form of teacher evaluation implemented in a western Canadian province. The potential for the teacher professional growth plan (TPGP) to become a process for individual development is examined from within the context of site-based management. We conclude that the TPGP provides a framework for teachers and administrators to analyze their own practice in the spirit of annual professional self renewal.
Student Teachers’ Perceptions of their Paired Practicum Placement Experiences
Authors: Bowen Michael , Roth Wolff-Michael
Published: April 2017

In this paper, we report our efforts to improve upon the difficulties traditionally experienced by preservice teachers while they are in their first field experience, such as resolving the gap between methodological approaches discussed in their “methods” class and the practicalities of the particular classroom setting they are teaching in (often referred to as the theory-practice gap). Drawing on our interviews with preservice teachers who taught in pairs, we report on the experience that such an environment for learning to teach provides to newcomers to the teaching profession. We theorize the experiences by drawing on two related theoretical frames that were developed to explain co-teaching and practical knowledge, respectively.
The Difference the Body Makes: The Teacher’s Presence Online and Offline
Authors: Henriksson Carina
Published: April 2017

This paper examines the question: what is the experience of meeting online and how does it differ from ordinary classroom situations? Drawing from personal experience, the author explores possible experiences of existing in virtual space and time. How do people meet, get to know each other and, interact in a pedagogical situation? Her experience as an online student made her to seriously reflect on the experiential nature of the computer-mediated encounter. But, it was not until she happened to participate in a workshop offered by the same teacher that the contrasts began to take shape for her. If there is a difference between online and offline meetings, what is it that makes the difference? Online communication could, just as face-to-face meetings, create feelings of closeness, and friendship; from the other-as-a-text on the screen, we subjectively create the other-as-an-idea, an idea that might be perceived as the real other. But is it? What reality is for real? What is the nature of the relationship established between

body-less persons on line, and what difference does the body make in a face-to-face meeting?
Promoting Teaching in Rural Schools
Authors: Ralph Edwin
Published: April 2017

This study extends previous investigations of interns’ and their

cooperating teachers’ views of teaching in rural schools, which were conducted in 1998, 1999, 2000, and 2001. The present paper includes findings from a survey conducted in 2002 of a fifth cohort of interns and their classroom cooperating teachers. It examined the same four items analyzed in the four previous studies (namely: the advantages of teaching in rural areas, the disadvantages of doing so, recommendations about practicum placements for future interns, and advice for these interns), as well as items that also solicited respondents’ views of what

the University’s College of Education and the rural school divisions could do to promote both interning and teaching in rural schools. Findings are synthesized and implications are drawn for both the University and the school divisions involved in these studies as well as for other institutions in similar situations—with respect to improving internship and teaching, and to helping promote the stability of rural communities, of which the school is often a key component.
Locating the Child in the Curriculum: Teachers' Conceptions of Student Individuality
Authors: Katz Steven , Foster Leanne
Published: April 2017

In this paper, we use the folk pedagogical construct to explicate the dilemma of teachers being poised between mandated curricula standards and the individual children they serve. By reference to a series of interviews with practicing teachers, we show that attempts to locate an individual child within the curriculum are mediated by the larger structural contexts within which the practices of teaching are inscribed. Teachers’ conceptions of student individuality are shown to assume a trait-like explanatory posture with individual differences being explained in terms of “kinds” as opposed to “degrees”. The resulting dynamic is one of an assumption of categorical homogeneity amongst members of particular “kinds”, as well as a substitution of behavioral and affective outcomes for cognitive ones when individuals are considered in relation to the class.
The Scholarship of College Teaching: Research Opportunities in the New Millennium
Authors: Fisher Roger
Published: April 2017

This paper examines some of the challenges facing contemporary Canadian community colleges and explores research opportunities related to (a) measuring the effectiveness of college teaching, (b) preparing beginning college teachers, and (c) re-conceptualizing professional development programs. First, the criteria for measuring teaching effectiveness at colleges are often derived from those used in elementary and secondary schools; questions remain as to whether, or to what degree, these criteria are appropriate measures of effective teaching in the college setting. Second, unprecedented retirements are creating an influx of beginning faculty with extensive subject expertise but often with little or no training as professional teachers; while traditional mentorship models often function as in-house induction programs, innovative pre-service training programs are being developed to more fully prepare aspirants to the profession of college teaching. Finally, some colleges are re-conceptualizing their professional development programs, employing innovative models such as Teaching Circles which are designed to build communities of scholars focused on institutional excellence in teaching. Numerous opportunities exist for research into teaching effectiveness, faculty induction, and professional development amid the changes and challenges that currently face the community colleges.
An Alternative Vision for Large-scale Assessment in Canada
Authors: Volante Louis
Published: April 2017

Concern over the quality of education has prompted virtually every Canadian province and territory to develop large-scale assessment programs to measure student achievement. The approach of individual provinces and territories varies according to the grades tested, sample size, test format, and frequency of administration. Many provinces also participate in national and international testing programs. This paper provides a general overview of the various large-scale assessment programs across Canada and outlines central arguments for and against student achievement testing. Research documenting the impact of large-scale testing on students and teachers is also reported. The discussion proposes an alternative vision for large-scale assessment aimed at supporting teachers’ instructional practices and student learning. A set of key considerations within this vision serve as a basis for assessment policy reform.
How Does Language Impact the Learning of Mathematics? Let Me Count the Ways
Authors: Boulet Genevieve
Published: April 2017

The role that language plays in the teaching and learning of mathematics is at the forefront of current literature in mathematics education. In this paper, I give particular attention to the manner in which teachers and students engage in the exploration of mathematical concepts and procedures with the goal of revealing how language impacts students’ learning. Through a series of examples of language commonly used in the mathematics classroom, I address specific issues pertaining to language used to describe mathematical processes, to read and interpret notation, and to define mathematical terms. Considering that communication is a key factor in the building of understanding, it is hoped that these examples will motivate teachers to examine and to adapt their own practices in order to cultivate productive and meaningful mathematical discourse in their classrooms.

The project is described with reference to related mathematical, haptic, kinesthetic and musical software development for mathematics learning and in light of justifications for an embodied, multisensory, and fluidly translatable mathematics immediately applicable by students in purposeful ways.
Unpacking Mathematics for Teaching: A Study of Preservice Elementary Teachers’ Evolving Mathematical Understandings and Beliefs
Authors: Kajander Ann
Published: April 2017

This study examined the mathematical understandings and beliefs held by preservice elementary teachers in a mathematics methods course taken as part of a one year teacher certification program, and re-examined these characteristics at the end of the course. The notion of ‘understanding mathematics for teaching’ was examined in a way that might begin to support the work of mathematics educators working with such preservice teacher candidates. Preservice teacher beliefs about what is important in mathematics learning and therefore the teaching of it are examined along with mathematics understanding at both procedural and conceptual levels. The goal is to shed some light on how initial understanding and beliefs about mathematics teaching co-exist, and how these might develop during a preservice teacher education program. A preliminary model designed to promote participant self-reflection is suggested.

Academic Service Learning as Pedagogy: An Approach to Preparing Preservice Teachers for Urban Classrooms
Authors: Sulentic Dowell Margaret-Mary
Published: April 2017

ABSTRACT

ACADEMIC SERVICE-LEARNING AS PEDAGOGY: AN APPROACH TO

PREPARING PRESERVICE TEACHERS FOR URBAN CLASSROOMS

Teacher education struggles with multifaceted and increasingly complex issues surrounding preparing majority (White) teachers to work effectively with minority (non-White) students, families and communities. Novice teachers entering the workforce need to be culturally responsive. What are the benefits to students, community, and university when academic service learning (AS-L) is a course component? How does AS-L impact the personal intellectual growth of preservice teachers?

This phenomenological qualitative study examined dispositions of 177 preservice teachers engaged in literacy and multicultural education courses with AS-L components. A nesting design was selected for this study situating preservice teachers in the center, surrounded by university teacher education coursework, which in turn, is surrounded by a larger circle encompassing local K-12 public schools and the community at large, where all are located.

Data were collected over the course of five consecutive semesters, using four different data sources, with written reflections the primary source. Ethnographic techniques of participant observation, informal and formal interviewing were also used to collect data. Artifacts and field notes resulting from observations and interview transcripts were considered when triangulating reflection data, comparing evidence from different sources and using multiple perceptions to clarify meaning. Using different data sources permitted examination of the same phenomena through different lens.

Data were analyzed using open coding, an inductive content analysis, and the constant comparative method, both systematic yet dynamic approaches. Comparing different data sources allowed for the comparison of views, situations, actions, and experiences of different individuals. Data analysis led to four significant categories: displacement, transformation, acceptance, and moving from negative, judgmental attitudes to positive, non-judgmental attitudes.

This investigation suggested that AS-L components improved and strengthened teacher education courses in terms of adequately preparing preservice teachers to teach successfully in urban environments. This study resulted in preservice teachers whose dispositions and appreciation of diversity and culturally responsive teaching increased.
