Publisher: name: Alberta Journal of Educational Research
Year: 2020

description: This paper explores the different approaches and instructional strategies of five instructors who have taught a mandatory Aboriginal Education course in a Canadian teacher education program. The findings are drawn from a broader study that examined the impact of self-reflective practices in Indigenous Education. Through semi-structured interviews, five course instructors shared what they believed to be meaningful instructional strategies in the course. Although each instructor shared their personal approach to the course, the four broad themes of story, land, art, and reflection emerged from their examples. These are discussed in relation to what is reported in the literature about the approaches and instructional strategies of Indigenous Education course instructors (Aveling, 2006; Dion, 2007; McInnes, 2017); this expands the conversation on meaningful pedagogies for Indigenous Education courses in initial teacher education. Keywords: Indigenous Education; teacher education; instructional strategies; pedagogical practices. Cet article explore les différentes approches et stratégies pédagogiques de cinq instructeurs qui ont enseigné un cours obligatoire d’éducation autochtone dans le cadre d’un programme de formation des enseignants au Canada. Les résultats sont tirés d’une étude plus vaste ayant porté sur l’impact des pratiques de réflexion personnelle en éducation autochtone. Cinq instructeurs ont partagé, par des entrevues semi-structurées, ce qu’ils croyaient être des stratégies pédagogiques significatives pour le cours. Même si chaque instructeur a partagé son approche personnelle au cours, quatre grands thèmes, soit le récit, le territoire, l’art et la réflexion, sont tout de même ressortis de leurs exemples. Ces thèmes font l’objet d’une discussion portant sur les approches et les stratégies pédagogiques des instructeurs d’éducation autochtone qui sont décrites dans la littérature (Aveling, 2006; Dion, 2007; McInnes, 2017). Cette discussion vient donc élargir la conversation sur les pédagogies significatives pour les cours d’éducation autochtone offerts dans le cadre de la formation des enseignants. Mots clés : éducation autochtone; formation des enseignants; stratégies pédagogiques; pratiques pédagogiques

Disproportionate collapse prevention analyses for mid-rise cross-laminated timber platform-type buildings
Creators: name: Mpidi Bita, Hercend
Publisher: name: University of British Columbia
Year: 2019

description: Abnormal loads which can cause initial damage may trigger collapse propagation, leading to disproportionate collapse of buildings with insufficient structural robustness. To ensure structural safety, design approaches against this catastrophic collapse are embodied within the building regulations. Nevertheless, the application of existing guidelines for disproportionate collapse prevention for mid- to high-rise mass-timber buildings -as an emerging construction method- becomes unpractical and uneconomic; and research studies in this topic are scarce. This thesis contributes to the body of knowledge with respect to structural robustness and disproportionate collapse prevention for mid-rise platform-type cross-laminated timber buildings through analytical, numerical, and experimental analyses. Nonlinear dynamic numerical analyses, using the sudden element removal, are performed on twelve- and nine-storey buildings to study their responses after initial damage. The analytical approach applies linear-elastic static equilibrium to estimate the minimum strength, stiffness, and ductility to ensure structural robustness. From subsequent reliability analysis, the results show that without considerations of the complexities associated with disproportionate collapse, mid-rise cross-laminated timber platform-type buildings have a high probability of disproportionate collapse. A structural optimisation procedure is then proposed to achieve a target performance and ensure structural safety. From the worst-case scenario, novel connection detailing is then proposed to trigger catenary and hanging actions as collapse resistance mechanisms. The proposed detailing using steel tubes and rods is numerically investigated and optimised. Then, results from experimental tests confirm that when the tubes and rods are implemented as floor-to-floor detailing, mass-timber floor system can trigger catenary action as a collapse resistance mechanism following the loss of internal loadbearing wall.
Type I and $new$ seesaw in left-right symmetric theories

description: We extend the Type I seesaw and suggest a $new$ seesaw mechanism to generate neutrino masses within the left-right symmetric theories where parity is spontaneously broken. We construct a next to minimal left-right symmetric model where neutrino masses are determined irrespective of the B-L breaking scale and call it the $new$ seesaw mechanism. In this scenario B-L scale can be very low. This makes B-L gauge boson and the quasi-Dirac $heavy$ leptons very light. These TeV scale particles could have large impact on lepton flavor and CP violating processes. We also shed light on the phenomenological aspects of the model within the reach of the LHC.

description: Performance  assessment  in  irrigation  systems  plays  a  vital  role  in  identifying  the  gaps
and  applying  mitigation  measures.  The  possible  benefits  of  the  Allawuha  irrigation
scheme  is  scarcely  understood,  hence  the  objective  of  the  study  was  evaluating  the
hydraulic performance of Allawuha small scale irrigation scheme. This study was carried
out for a single irrigation season from February to June, 2016. Hydraulic performance of
the scheme was evaluated by comparing irrigation water demand with actual supply, and
using  10  internal  process  indicators  classified  under  water  delivery,  utility  of  water
supply and maintenance indicators. As per the result, deficit of supply has been advanced
in April and May; hence actual irrigation water supply was 35.16 % in April and 25.53 in
May  more  than  the  demand.  However,  supply  was  exceeding  the  demand  by  60.47%
during  March.  On  average,  irrigation  water  supply  was  observed  in  shortage  of  the
requirement at  the  outlet point one, three and five, whereas in excess of the requirement
at  the  outlet  point  two  and  four.  The  overall  water  delivery  performance  indicators;
adequacy,  dependability,  equity  and  efficiency  were  found  to  be  0.56,  0.47,  0.0.22  and
0.96 respectively. According to these values, performance of water delivery canals was
rated as poor in terms of adequacy and dependability; however it was good and fair in
relation  to  efficiency  and  equity  respectively.  Utility  of  water  supply  indicators;
deficiency, delivery performance ratio  and  equity ratio for head to tail were found to be
0.30, 0.63, and 2.73 respectively. These values indicate that, the performance of the main
canal was declining from the intended and distribution of water between the head and tail
was  unfair.  Maintenance  indicators;  water  surface  elevations  ratio,  effectiveness  of
infrastructure  and  sustainability  of  irrigated  area  were  found  to  be  78%,  26.09%  and
97.8%  respectively.  These  values  indicate  that,  actual  water  level  as  well  as  command
area was reduced from initially designed, and a number of structures initially installed
were becoming nonfunctional,  then maintenance of the system is necessary.  The results
from this study are very clear to that of, non-proportionality of irrigation water demand
with supply, poor temporal water delivery system, absence of frequent maintenance, and
management  aspects  have  been  strongly  affected  the  hydraulic  performance  of  the
schemes.  Therefore,  it  is  suggested  that,  frequent  maintenance,  optimal  crop  plan,  and
apply a strong water delivery plan are required to mitigate these problems

description: In 2010, the United Nations Committee on the Peaceful Uses of Outer Space began consideration of a new agenda item under a three-year work plan on the International Space Weather Initiative (ISWI). The main objectives of ISWI are to contribute to the development of the scientific insight necessary to improve understanding and forecasting capabilities of space weather as well as to education and public outreach. The United Nations Programme on Space Applications, implemented by the Office for Outer Space Affairs, is implementing ISWI in the framework of its United Nations Basic Space Science Initiative (UNBSSI), a long-term effort, launched in 1991, for the development of basic space science and for international and regional cooperation in this field on a worldwide basis, particularly in developing countries. UNBSSI encompassed a series of workshops, held from 1991 to 2004, which addressed the status of basic space science in Africa, Asia and the Pacific, Latin America and the Caribbean, and Western Asia. As a result several small astronomical research facilities have been inaugurated and education programmes at the university level were established. Between 2005 and 2009, the UNBSSI activities were dedicated to promoting activities related to the International Heliophysical Year 2007 (IHY), which contributed to the establishment of a series of worldwide ground-based instrument networks, a node of which is also operated by the Office for Outer Space Affairs. Building on these accomplishments, UNBSSI is now focussing on the ISWI.

description: Recent observations show that spiral galaxies are surrounded by extended gaseous halos as predicted by the hierarchical structure formation scenario. The origin and nature of extraplanar gas is often unclear since the halo is continuously fueled by different circulation processes as part of the on-going formation and evolution of galaxies (e.g., outflows, galaxy merging, and gas accretion from the intergalactic medium). We use the Milky Way as a laboratory to study neutral and mildly ionised gas located in the inner and outer halo. Using spectral line absorption and emission measurements in different wavelength regimes we obtain detailed information on the physical conditions and the distribution of the gas. Such studies are crucial for our understanding of the complex interplay between galaxies and their gaseous environment as part of the formation and evolution of galaxies. Our analysis suggests that the column-density distribution and physical properties of gas in the Milky Way halo are very similar to that around other disk galaxies at low and high redshifts.

Performance Assessment of small-scale irrigation schemes  based on  the condition of before and after modernization  (A  case study of Meka Small Scale Irrigation Scheme)
Creators: name: Yalew Belete
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2008

description: This  study  attempted  to  investigate  the  performance  of  Meka  SSI  scheme, which
is  representative  of  "modern"  community  managed  SSI  Schemes  in  Dry  Dega
Agro-Climatic Areas  of  North  Shoa  Zone,  Amhara  National  Regional  state.  Field
data  measurements,  household  surveys  and  key  informant  discussions  were
employed  to  investigate  the  extent  to  which  upgrading  of  traditional  irrigation
schemes  improves  its  performance  based  on  the  condition  of  before  and  after
"modernization".  The  results  indicated  that  irrigation water delivery systems were
characterized  by  rigid,  inequitable  and  unreliable  water  delivery  schedules.  The
weighted  average  application  efficiency,  storage  efficiency  and  distribution
uniformity  at  scheme  level  were  found  to  be  66.10%,  95.13%  and  67.25%
respectively.  Low  distribution  uniformity  and  application  efficiency  coupled  with
high storage efficiency  indicated high water losses.  In general, as  per the  results of
the  survey,  irrigation  modernization/upgrading  provided  dramatic  achievements
such  as  increment  in  command  area,  increment  in  water  supply,  introduction  of water  fee  collection,  greater  confidence  in  the  use  of  inputs;  and  enhanced
awareness  of  farmers  towards  irrigation  practice.  However,  the  realizations  of  the
benefits  of  modernization were  constrained  by  rigid  delivery  schedules,  and  rigid
irrigation  practices.  Thus,  the  adoption  of  improved  hardware  is  not  by  itself
enough  to  attain  high  levels  of  performance.  Therefore,  there  is  a  need  for
improvement  in  the  design  of  water  application  practices,  irrigation  scheduling
techniques  and  system  operational  policies  (water  delivery  schedules)  of  the
irrigation  scheme.

description: In this work, we solve the problem of finding the best locations to place stations for depositing/collecting shared bicycles. To do this, we model the problem as the p-median problem, that is a major existing localization problem in optimization. The p-median problem seeks to place a set of facilities (bicycle stations) in a way that minimizes the distance between a set of clients (citizens) and their closest facility (bike station). We have used a genetic algorithm, iterated local search, particle swarm optimization, simulated annealing, and variable neighbourhood search, to find the best locations for the bicycle stations and study their comparative advantages. We use irace to parameterize each algorithm automatically, to contribute with a methodology to fine-tune algorithms automatically. We have also studied different real data (distance and weights) from diverse open data sources from a real city, Malaga (Spain), hopefully leading to a final smart city application. We have compared our results with the implemented solution in Malaga. Finally, we have analyzed how we can use our proposal to improve the existing system in the city by adding more stations.

description: We construct a model of decaying, TeV-scale scalar dark matter motivated by data from the PAMELA and Fermi-LAT experiments. By introducing an appropriate Abelian discrete symmetry and an intermediate scale of vector-like states that are responsible for generating lepton Yukawa couplings, we show that Planck-suppressed corrections may lead to decaying dark matter that is leptophilic and has the desired lifetime. The dark matter candidate decays primarily to lepton/anti-lepton pairs, and at a subleading rate to final states with a lepton, anti-lepton and standard model Higgs boson. We show that the model can reproduce the observed positron flux and positron fraction while remaining consistent with the bounds on the cosmic ray antiproton flux.

description: The global COVID-19 pandemic poses challenges to the economy, politics and public health systems of developed and developing countries alike. However, the latter are less well placed to cope with adverse effects. In particular, important advances towards sustainable development might be reversed. Tackling the pandemic and its effects therefore requires global cooperation as well as solidarity in the form of development assistance. Yet, support for development assistance among donor publics might be dampened by individual health-related and economic worries as well as decreasing trust in government during the pandemic. Against this backdrop, we investigate the possible effect of pandemic-induced worries on public support for development assistance as well as the moderating role of moral considerations and trust in government. Drawing on literature on aid attitudes, and using survey data for Germany provided by the COVID-19 Snapshot Monitoring (COSMO) project from April 2020 (N = 1,006), our analyses show that neither health-related nor economic worries are associated with less support for providing development assistance during the first wave of the pandemic. However, we observe a marginal interaction between health-related worries and trust in government in predicting support for development assistance. For those with high levels of trust in government the effect of worry regarding the loss of friends or relatives on support for development assistance is positive, whereas it is close to zero for those with low levels of trust. We conclude that at the peak of the first wave of the pandemic there was little need for concern by policy-makers endorsing development assistance as neither form of worry correlated negatively with public support for development assistance and trust was high. However, when worries recur and trust in government simultaneously decreases, public support for global solidarity may wane.

Nevertheless, since in an educational context such information may be deemed insufficient, it would be beneficial for both the student and the instructor to receive additional feedback about the overall development of the task. This work aims to tackle this limitation by considering the further exploitation of the information gathered by the OJ and automatically inferring feedback for both the student and the instructor. More precisely, we consider the use of learning-based schemes -- particularly, multi-instance learning (MIL) and classical machine learning formulations -- to model student behavior. Besides, explainable artificial intelligence (XAI) is contemplated to provide human-understandable feedback. The proposal has been evaluated considering a case of study comprising 2500 submissions from roughly 90 different students from a programming-related course in a computer science degree. The results obtained validate the proposal: The model is capable of significantly predicting the user outcome (either passing or failing the assignment) solely based on the behavioral pattern inferred by the submissions provided to the OJ. Moreover, the proposal is able to identify prone-to-fail student groups and profiles as well as other relevant information, which eventually serves as feedback to both the student and the instructor.

description: The perpendicular magnetic anisotropy (PMA) arising at the interface between ferromagnetic transition metals and metallic oxides are investigated via first-principles calculations. In this work very large values of PMA up to 3 erg/cm$^2$ at Fe$|$MgO interfaces are reported in agreement with recent experiments. The origin of PMA is attributed to overlap between O-$p_z$ and transition metal $d_{z^2}$ orbitals hybridized with $d_{xz(yz)}$ orbitals with stronger spin-orbit coupling induced splitting around the Fermi level for perpendicular magnetization orientation. Furthemore, it is shown that the PMA value weakens in case of over- or underoxidation when oxygen $p_z$ and transition metal $d_{z^2}$ orbitals overlap is strongly affected by disorder, in agreement with experimental observations in magnetic tunnel junctions.

CONDITION ASSESMENT AND MODELING OF GROUND  WATER  IN  ARBAMINCH AREA
Creators: name: SAMUEL DAGALO
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2005

description: When  the  issue  of  water  supply  and  demand  for  a  certain  purpose  is  raised,  the
case  of  the  availability  of  source  of  water  and  assessment  of  its  conditions  are
inseparable considerations.
Assessment  of  conditions  of  Groundwater  in  an  area  may  include  the  water
withdrawal  rate,  its  utilization  and management,  the  type  of  formations  from which  it
is  coming,  the  hydro  geological  properties,  quality  conditions  of  Ground  Water,
presence of  influx (recharge) and more others.
The water  supply  and  demand  condition  of  Arba  Minch  University  has  been  dealt
with. The  presence  of  high  losses  (60-95%  of  the  pumped water)  in  the  distribution
system has been detected.
The  type  of  aquifers  from which  this supply  is withdrawn  has been  determined. The
area  is  highly  heterogeneous  and  anisotropic  with  the  transmissivity  of  aquifer
varying between 2 to 532.3m2
per day. The Groundwater flow direction  in the area  is
towards  the Lake  (Abaya)  determined with the aid of water  level contour interpolated in the Arc view GIS.
A natural  scene  of  higher values  of  Groundwater  constituents  and  parameters  has
been  observed  near  Lake Abaya with  the  general  trend  of  decreasing  upstream  to An  approximate  soil-water  balance  approach  to  determine  Groundwater  recharge
from  rainfall  after  the  necessary  accounting  of  run-off,  evapotranspiration  and  soil
moisture  storage  requirements  indicated  very  little/  no  recharge  from  rainfall  in  the
area.
A  simplified,  homogeneous  and  anisotropic  steady  state  Groundwater  flow  model
with  a  single  confined  aquifer  having  the  varying  transmissivity  of  the  actual  multi­
layer aquifer system  has  been developed. The available MODFLOW software called
Processing MODDLOW for Windows  (PMWIN) has been adopted for model  run.
Calibrations with  few  point data of water  levels  from  field measurements at  available
and  selected  control  points  has  been  done  by  varying  and  computing  parameters
and  conditions  at  a  time.  Of  all  the  parameters  Ground water  level  (head)  is  very
sensitive to variations of  transmissivity and aerial  recharge values. Prediction  of  the model  run was  considered  for the sustainability of  the existing wells
and well  No-7  (AMU-7)  for the  current and  future  population with  reference  to  some
head  values which  could  be attained  in  the wells due to  excessive  pumping  in  these
wells. With  the  preset  head  values  in  the  wells  (considered  'undesirable  head"  for
each  well)  scenarios  have  been  developed  for  varying  combinations  of  discharge.
Well  No-7  has  been  proved  to  be  a  good  potential  well  for  current  and  future
population, could supply about 501/sec without appreciable head drop.

description: We propose an improved effective-medium theory to obtain the concentration dependence of the viscosity of particle suspensions at arbitrary volume fractions. Our methodology can be applied, in principle, to any particle shape as long as the intrinsic viscosity is known in the dilute limit and the particles are not too elongated. The procedure allows to construct a continuum-medium model in which correlations between the particles are introduced through an effective volume fraction. We have tested the procedure using spheres, ellipsoids, cylinders, dumbells, and other complex shapes. In the case of hard spherical particles, our expression improves considerably previous models like the widely used Krieger-Dougherty relation. The final expressions obtained for the viscosity scale with the effective volume fraction and show remarkable agreement with experiments and numerical simulations at a large variety of situations.

description: Management and sustainability of rural water supply is a big challenge, in water delivery
service. The main objective of this study was for assessing sustainability and management
of rural water supply systems in Debark Wereda  Amhara region, Ethiopia. Nine  sample
Kebeles  were  chosen  by  cluster  sampling.  Survey  was  carried  out  (n=191)  users  and
artisans  (caretakers)  to  fill  the  questionnaire  in  fifteen  purposely  selected  water  points
constructed in  the last few years.  Both  Primary  and  secondary  data  were employed.  The
collected  data  were  scored;  standardized,  analyzed  and  interpreted  using  project
approach  and  performance  frameworks  within  NUMXL1.6  software  and  STATA  12.
Sample water points were ranked depending on the index and its values mapped with Arc
GIS  10.2.  Demand  driven  approach,  users  participation,  committee  training,  choice  of
technology were factors which affects pre  and  post project implementation  which results
poor  management  and  sustainability  of  sample  projects.  From  the  analysis  54%  which
was  not  satisfactory  and  good  enough.  18%  of  sample  water  points  categorized  as
ineffectiveness  or  non-functional  and  not  long-lasting  to  deliver  the  anticipated  service
because of poor project  approach  and performance  frameworks.  From the result 23.4%
of  sample  projects  fall  under  effective  and  sustainable  water  points  with  little
modification.  Community managed projects  have greater  Effectiveness  and Sustainability
index  results  than  non-community  managed  projects  this  implies  Community  managed
projects  well  performed  than  non-community  managed  projects.  Finally,  the
recommended design of spring water scheme was design by using auto cad software.
Teaching Indigenous Literatures for Decolonization: Challenging Learning, Learning to Challenge
Creators: name: Hanson, Aubrey Jean
Publisher: name: Alberta Journal of Educational Research

description: This paper examines the significance of colonial contexts that influence the teaching of Indigenous literatures. It draws upon conversations I held with Indigenous writers and with secondary educators, in which we discussed the relationships between Indigenous communities, Indigenous literatures, and classroom teaching in Canada. In dialogue with teachers’ and authors’ perspectives, this paper argues that, when Indigenous stories are told and taught, readers are invited to challenge colonial understandings and are implicated into challenging classroom experiences. The pedagogical experiences precipitated by Indigenous literatures can be difficult for teachers and students, leading to unsettling dynamics, but are importantly decolonizing. Keywords: Indigenous literatures, Indigenous education, decolonization, resurgence, métissage Cet article examine la signification des contextes coloniaux qui influencent l’enseignement des littératures autochtones. Il puise dans des conversations que j’ai eues avec des écrivains autochtones et des enseignants du secondaire au cours desquelles nous avons discuté des rapports entre les communautés autochtones, les littératures autochtones et l’enseignement en classe au Canada. S’appuyant sur les perspectives des enseignants et des auteurs, l’article soutient que lorsqu’on raconte ou qu’on enseigne des récits autochtones, on invite les lecteurs à remettre en question des perspectives coloniales et à participer à des expériences stimulantes en classe. Les expériences pédagogiques précipitées par les littératures autochtones peuvent s’avérer difficiles pour les enseignants et les élèves, et une dynamique perturbante peut en découler, mais leur rôle dans la décolonisation est important.

description: The small-scale magnetic helicity produced as a by-product of the large-scale dynamo is believed to play a major role in dynamo saturation. In a mean-field model the generation of small-scale magnetic helicity can be modelled by using the dynamical quenching formalism. Catastrophic quenching refers to a decrease of the saturation field strength with increasing Reynolds number. It has been suggested that catastrophic quenching only affects the region of non-zero helical turbulence (i.e. where the kinematic alpha operates) and that it is possible to alleviate catastrophic quenching by separating the region of strong shear from the alpha layer. We perform a systematic study of a simple axisymmetric two-layer alpha-omega dynamo in a spherical shell for Reynolds numbers in the range 1 < Rm < 10^5. In the framework of dynamical quenching we show that this may not be the case, suggesting that magnetic helicity fluxes would be necessary.

description: The atomic deposited BN films with the thickness of nanometers (ABN) were prepared by radio frequency magnetron sputtering method and the nanostructured BN films (CBN) were prepared by Low Energy Cluster Beam Deposition. UV-Vis Absorption measurement proves the band gap of 4.27eV and field emission of the BN films were carried out. F-N plots of all the samples give a good fitting and demonstrate the F-N tunneling of the emission process. The emission of ABN begins at the electric field of 14.6 V/μm while that of CBN starts at 5.10V/μm. Emission current density of 1mA/cm2 for ABN needs the field of 20V/μm while that of CBN needs only 12.1V/μm. The cluster-deposited BN on n-type Silicon substrate proves a good performance in terms of the lower gauge voltage, more emission sites and higher electron intensity and seems a promising substitute for the cascade of Field Emission.
Constraints Influencing the Efficacy of a PGCE Mathematics Program: A Case Study

description: The learning attainment of South African learners in mathematics is, as The International Mathematics and Science Study (TIMSS) data reveal, far from optimal. A key contributing factor is a shortage of competent and confident qualified mathematics teachers. The Post Graduate Certificate in Education (PGCE) offered at South African universities is a key qualification designed to address this challenge (amongst others, such as the Bachelor of Education [B.Ed.]). However, the success of the PGCE as a preparation for mathematics teachers is not without concern, as this paper argues. Using a qualitative case study focusing on a PGCE with a mathematics focus offered by a university of technology, this paper discusses the constraints identified by prospective teachers and teacher educators. Constraints are explored by focusing on the curriculum, partnerships, and policy relating to the delivery of the PGCE as true and critical to the efficacy of the program. The paper contributes to context-specific understanding of the constraints influencing the PGCE’s efficacy (as offered in 2014) in developing newly qualified teachers’ (NQTs) skills and knowledge to be confident and competent mathematics teachers. Keywords: Post Graduate Certificate in Education; mathematics; learning to teach; governance; curriculum. Les données d’une enquête internationale portant sur les acquis scolaires en mathématiques et en sciences (TIMSS) révèlent que le rendement des apprenants sud-africains en mathématiques est loin d’être optimal. Un facteur qui contribue de façon significative à ce phénomène est le manque d’enseignants qualifiés qui sont compétents et confiants. Le certificat d’études supérieures en éducation (PGCE) offert dans les universités en Afrique du Sud est une qualification importante conçue pour faire face à ce défi (le Baccalauréat en Éducation, entre autres). Toutefois, la réussite du PGCE comme outil de préparation pour les enseignants n’est pas sans inquiétude, comme le soutient cet article. En s’appuyant sur une étude de cas qualitative portant sur un PGCE avec une majeur en mathématiques et offert par une université de technologie, cet article discute des contraintes identifiées par de futurs enseignants et formateurs d’enseignants. Les contraintes sont examinées en se penchant sur le curriculum, les partenariats et les politiques relatives à la prestation du PGCE pour évaluer dans quelle mesure ils sont véritables et essentiels au programme. Cet article contribue à une compréhension, propre au contexte, des contraintes qui influencent l’efficacité du PGCE (tel qu’offert en 2014) à développer les compétences et les connaissances de nouveaux diplômés pour qu’ils soient des enseignants confiants et compétents.
