Abstract. Kraków is routinely affected by very high air pollution
levels, especially during the winter months. Although a lot of effort has
been made to characterize ambient aerosol, there is a lack of online
and long-term measurements of non-refractory aerosol. Our measurements at
the AGH University of Science and Technology provide the online long-term chemical composition of ambient
submicron particulate matter (PM1) between January 2018 and April 2019.
Here we report the chemical characterization of non-refractory submicron
aerosol and source apportionment of the organic fraction by positive matrix
factorization (PMF). In contrast to other long-term source apportionment
studies, we let a small PMF window roll over the dataset instead of
performing PMF over the full dataset or on separate seasons. In this way,
the seasonal variation in the source profiles can be captured. The
uncertainties in the PMF solutions are addressed by the bootstrap resampling
strategy and the random a-value approach for constrained factors. We observe clear seasonal patterns in the concentration and composition of
PM1, with high concentrations during the winter months and lower
concentrations during the summer months. Organics are the dominant species
throughout the campaign. Five organic aerosol (OA) factors are resolved, of
which three are of a primary nature (hydrocarbon-like OA (HOA), biomass
burning OA (BBOA) and coal combustion OA (CCOA)) and two are of a secondary
nature (more oxidized oxygenated OA (MO-OOA) and less oxidized oxygenated OA
(LO-OOA)). While HOA contributes on average 8.6 % ± 2.3 %
throughout the campaign, the solid-fuel-combustion-related BBOA and CCOA
show a clear seasonal trend with average contributions of 10.4 % ± 2.7 % and 14.1 %, ±2.1 %, respectively. Not only BBOA but
also CCOA is associated with residential heating because of the pronounced
yearly cycle where the highest contributions are observed during wintertime.
Throughout the campaign, the OOA can be separated into MO-OOA and LO-OOA
with average contributions of 38.4 % ± 8.4 % and 28.5 % ± 11.2 %, respectively.
Spaceborne differential absorption radar water vapor retrieval capabilities in tropical and subtropical boundary layer cloud regimes
Authors: Roy Richard J. , Lebsock Matthew , Kurowski Marcin J.
Published: October 2021

Abstract. Differential absorption radar (DAR) near the 183 GHz water vapor absorption line is an emerging measurement technique for humidity profiling inside of clouds and precipitation with high vertical resolution, as well as for measuring integrated water vapor (IWV) in clear-air regions. For radar transmit frequencies on the water line flank away from the highly attenuating line center, the DAR system becomes most sensitive to water vapor in the planetary boundary layer (PBL), which is a region of the atmosphere that is poorly resolved in the vertical by existing spaceborne humidity and temperature profiling instruments. In this work, we present a high-fidelity, end-to-end simulation framework for notional spaceborne DAR instruments that feature realistically achievable radar performance metrics and apply this simulator to assess DAR's PBL humidity observation capabilities. Both the assumed instrument parameters and radar retrieval algorithm leverage recent technology and algorithm development for an existing airborne DAR instrument. To showcase the capabilities of DAR for humidity observations in a variety of relevant PBL settings, we implement the instrument simulator in the context of large eddy simulations (LESs) of five different cloud regimes throughout the trade-wind subtropical-to-tropical cloud transition. Three distinct DAR humidity observations are investigated: IWV between the top of the atmosphere and the first detected cloud bin or Earth's surface; in-cloud water vapor profiles with 200 meter vertical resolution; and IWV between the last detected cloud bin and the Earth's surface, which can provide a precise measurement of the sub-cloud humidity. We provide a thorough assessment of the systematic and random errors for all three measurement products for each LES case and analyze the humidity precision scaling with along-track measurement integration. While retrieval performance depends greatly on the specific cloud regime, we find generally that for a radar with cross-track scanning capability, in-cloud profiles with 200 m vertical resolution and 10 %–20 % uncertainty can be retrieved for horizontal integration distances of 100–200 km. Furthermore, column IWV can be retrieved with 10 % uncertainty for 10–20 km of horizontal integration. Finally, we provide some example science applications of the simulated DAR observations, including estimating near-surface relative humidity using the cloud-to-surface column IWV and inferring in-cloud temperature profiles from the DAR water vapor profiles by assuming a fully saturated environment.
Modeling the marine chromium cycle: new constraints on global-scale processes
Authors: Pöppelmeier Frerk , Janssen David J. , Jaccard Samuel L. , Stocker Thomas F.
Published: October 2021

Abstract. Chromium (Cr) and its isotopes hold great promise as a
tracer of past oxygenation and marine biological activity due to the
contrasted chemical properties of its two main oxidation states, Cr(III) and
Cr(VI), and the associated isotope fractionation during redox
transformations. However, to date the marine Cr cycle remains poorly
constrained due to insufficient knowledge about sources and sinks and the
influence of biological activity on redox reactions. We therefore
implemented the two oxidation states of Cr in the Bern3D Earth system model
of intermediate complexity in order to gain an improved understanding on
the mechanisms that modulate the spatial distribution of Cr in the ocean.
Due to the computational efficiency of the Bern3D model we are able to
explore and constrain the range of a wide array of parameters. Our model
simulates vertical, meridional, and inter-basin Cr concentration gradients
in good agreement with observations. We find a mean ocean residence time of
Cr between 5 and 8 kyr and a benthic flux, emanating from sediment
surfaces, of 0.1–0.2 nmol cm−2 yr−1, both in the range of previous
estimates. We further explore the origin of regional model–data mismatches
through a number of sensitivity experiments. These indicate that the benthic
Cr flux may be substantially lower in the Arctic than elsewhere. In
addition, we find that a refined representation of oxygen minimum zones and
their potential to reduce Cr yield Cr(III) concentrations and Cr removal
rates in these regions in much improved agreement with observational data.
Yet, further research is required to better understand the processes that
govern these critical regions for Cr cycling.
UNLOCKING POINT CLOUD POTENTIAL: FUSING MLS POINT CLOUDS WITH SEMANTIC 3D BUILDING MODELS WHILE CONSIDERING UNCERTAINTY
Authors: Wysocki O. , Xu Y. , Stilla U.
Published: October 2021

Abstract. Throughout the years, semantic 3D city models have been created to depict 3D spatial phenomenon. Recently, an increasing number of mobile laser scanning (MLS) units yield terrestrial point clouds at an unprecedented level. Both dataset types often depict the same 3D spatial phenomenon differently, thus their fusion should increase the quality of the captured 3D spatial phenomenon. Yet, each dataset has modality-dependent uncertainties that hinder their immediate fusion. Therefore, we present a method for fusing MLS point clouds with semantic 3D building models while considering uncertainty issues. Specifically, we show MLS point clouds coregistration with semantic 3D building models based on expert confidence in evaluated metadata quantified by confidence interval (CI). This step leads to the dynamic adjustment of the CI, which is used to delineate matching bounds for both datasets. Both coregistration and matching steps serve as priors for a Bayesian network (BayNet) that performs application-dependent identity estimation. The BayNet propagates uncertainties and beliefs throughout the process to estimate end probabilities for confirmed, unmodeled, and other city objects. We conducted promising preliminary experiments on urban MLS and CityGML datasets. Our strategy sets up a framework for the fusion of MLS point clouds and semantic 3D building models. This framework aids the challenging parallel usage of such datasets in applications such as façade refinement or change detection. To further support this process, we open-sourced our implementation.
A CONCEPTUAL MODEL FOR IFC-BASED DELINEATION OF CONDOMINIUM RIGHTS IN TURKEY: INITIAL EXPERIMENTS
Authors: Guler D. , Yomralioglu T.
Published: October 2021

Abstract. Owing to the increasing existence of multistorey buildings and infrastructures in the built environment, there is a need for three-dimensional (3D) land administration systems (LAS). Regarding this, condominium rights in real-estate properties are needed to be represented as 3D for preventing misinterpretations with regards to who is responsible for or has ownership in which parts of the buildings. Digitalizing the public services appears in current strategies of governments and administrations since it contributes to transparency, speed, and accurateness in the processes. Building permitting that contains obtaining the occupancy permit is a vital one of these public services. With the even-increasing adaptation of Building Information Modelling (BIM), a whole raft of Building Information Models (BIMs) are created to use in digital building permitting. Thus, a significant opportunity for 3D delineation of condominium rights comes out of the reuse of these BIMs, especially their Industry Foundation Classes (IFC) data. In this sense, this paper puts forward an approach that includes developing the conceptual model to depict condominium rights and linking that model with the IFC schema. The applicability of the approach is demonstrated by using a floor of a simple building. The study shows that IFC-based representation of condominium rights can be beneficial for the transition to 3D LAS in Turkey.
USING SIMULATION DATA FROM GAMING ENVIRONMENTS FOR TRAINING A DEEP LEARNING ALGORITHM ON 3D POINT CLOUDS
Authors: Spiegel S. , Chen J.
Published: October 2021

Abstract. Deep neural networks (DNNs) and convolutional neural networks (CNNs) have demonstrated greater robustness and accuracy in classifying two-dimensional images and three-dimensional point clouds compared to more traditional machine learning approaches. However, their main drawback is the need for large quantities of semantically labeled training data sets, which are often out of reach for those with resource constraints. In this study, we evaluated the use of simulated 3D point clouds for training a CNN learning algorithm to segment and classify 3D point clouds of real-world urban environments. The simulation involved collecting light detection and ranging (LiDAR) data using a simulated 16 channel laser scanner within the the CARLA (Car Learning to Act) autonomous vehicle gaming environment. We used this labeled data to train the Kernel Point Convolution (KPConv) and KPConv Segmentation Network for Point Clouds (KP-FCNN), which we tested on real-world LiDAR data from the NPM3D benchmark data set. Our results showed that high accuracy can be achieved using data collected in a simulator.
CITYGML APPLICATION DOMAIN EXTENSION FOR 3D STRATA REPRESENTATIONS IN THE SMARTKADASTER SYSTEM: TOWARDS BEYOND CADASTRE PURPOSE IN MALAYSIA
Authors: Siew C. B. , Abdul Halim N. Z. , Karim H. , Mohd Zain M. A. , Looi K. S.
Published: October 2021

Abstract. Recent advancements in 3D city modelling and emerging trends in implementing and realising Digital Twins motivate the Department of Survey and Mapping Malaysia (JUPEM) to develop and implement SmartKADASTER (SKiP) Phase 2. SmartKADASTER Phase I was a precursor to this system, and it primarily focused on applying two-dimensional (2D) spatial data for 3D spatial analysis. CityGML was used as the data model for various Levels of Detail (LoD) in this new initiative to represent city models across the Greater Kuala Lumpur region. SmartKADASTER however, lacks strata information. Therefore, to integrate strata information into the SKiP citymodel environment, an Application Domain Extension (ADE) for CityGML has been developed to convert existing Strata XML to StrataGML, a CityGML-compliant data output format. This paper describes the purpose of the SmartKADASTER initiative in Section 1. Section 2 explains additional context for the initiative as well as some backgrounds. Section 3 discusses the conversion workflow and ADE definitions, followed by a brief discussion of visualisation in Section 4 and a project summary in Section 5.
TOWARDS A DIGITAL TWIN OF A STORAGE TANK USING LASER SCAN DATA
Authors: Truong-Hong L. , Nguyen N. , Lindenbergh R. , Fisk P. , Huynh T.
Published: October 2021

Abstract. This paper proposes a methodology to automatically extract components of an oil storage tank from terrestrial laser scanning (TLS) point clouds, and subsequently to create a three-dimensional (3D) solid model of the tank for numerical simulation. The proposed method is integrated into a smart analysis layer of a digital twin platform consisting of three main layers: (1) smart analysis, (2) data storage, and (3) visualisation and user interaction. In this proposed method, primary components of the tank were automatically extracted in a consecutive order from a shell wall to roof and floor. Voxel-based RANSAC is employed to extract voxels containing point clouds of the shell wall, while a valley-peak-valley pattern based on kernel density estimation is implemented to remove outlier points within voxels representing to the shell wall and re-extract data points within voxels adjoined to the shell wall. Moreover, octree-based region growing is employed to extract a roof and floor from remaining point clouds. An experimental showed that the proposed framework successfully extracted all primary components of the tank and created a 3D solid model of the tank automatically. Resulting point clouds of the shell wall were directly used for estimating deformation and a 3D solid model was imported into finite element analysis (FEA) software to assess the tank in terms of stress-strain. The demonstration shows that TLS point clouds can play an important role in developing the digital twin of the oil storage tank.
AUTOMATIC 3D BUILDING MODEL GENERATION USING DEEP LEARNING METHODS BASED ON CITYJSON AND 2D FLOOR PLANS
Authors: Kippers R. G. , Koeva M. , van Keulen M. , Oude Elberink S. J.
Published: October 2021

Abstract. In the past decade, a lot of effort is put into applying digital innovations to building life cycles. 3D Models have been proven to be efficient for decision making, scenario simulation and 3D data analysis during this life cycle. Creating such digital representation of a building can be a labour-intensive task, depending on the desired scale and level of detail (LOD). This research aims at creating a new automatic deep learning based method for building model reconstruction. It combines exterior and interior data sources: 1) 3D BAG, 2) archived floor plan images. To reconstruct 3D building models from the two data sources, an innovative combination of methods is proposed. In order to obtain the information needed from the floor plan images (walls, openings and labels), deep learning techniques have been used. In addition, post-processing techniques are introduced to transform the data in the required format. In order to fuse the extracted 2D data and the 3D exterior, a data fusion process is introduced. From the literature review, no prior research on automatic integration of CityGML/JSON and floor plan images has been found. Therefore, this method is a first approach to this data integration.
Lasting impact of winds on Arctic sea ice through the ocean's memory
Authors: Wang Qiang , Danilov Sergey , Mu Longjiang , Sidorenko Dmitry , Wekerle Claudia
Published: October 2021

Abstract. In this paper we studied the impact of winds on Arctic sea ice through the ocean's memory by using numerical simulations. We found that the changes in halosteric height induced by wind perturbations can significantly affect the Arctic sea ice drift, thickness, concentration and deformation rates regionally even years after the wind perturbations. Changes in the Arctic liquid freshwater content and thus in halosteric height can cause changes in the sea surface height and surface geostrophic currents, which further enforce a lasting and strong impact on sea ice. The changes in both sea surface height gradient force (due to changes in sea surface height) and ice–ocean stress (due to changes in surface geostrophic currents) are found to be important in determining the overall ocean effects. The revealed ocean effects are mainly associated with changes in sea ice dynamics, not thermodynamics. Depending on the preceding atmospheric mode driving the ocean, the ocean's memory of the wind forcing can lead to changes in Arctic sea ice characteristics with very different spatial patterns. We obtained these spatial patterns associated with Arctic Oscillation, Arctic Dipole Anomaly and Beaufort High modes through dedicated numerical simulations. The dynamical impact of the ocean has strong seasonal variations, stronger in summer and weaker in winter and spring. This implies that declining trends of Arctic sea ice will very possibly allow a stronger ocean impact on the sea ice in a warming climate.
Semi-automated tracking of iceberg B43 using Sentinel-1 SAR images via Google Earth Engine

Published: October 2021

Abstract. Sentinel-1 C-band synthetic aperture radar (SAR) images can be used to observe the drift of icebergs over the Southern Ocean with around 1–3 d of temporal resolution and 10–40 m of spatial resolution. The Google Earth Engine (GEE) cloud-based platform allows processing of a large quantity of Sentinel-1 images, saving time and computational resources. In
this study, we process Sentinel-1 data via GEE to detect and track the drift of iceberg B43 during its lifespan of 3 years (2017–2020) in the Southern Ocean. First, to detect all candidate icebergs in Sentinel-1 images, we employ an object-based image segmentation (simple non-iterative clustering – SNIC) and a traditional backscatter threshold method. Next, we automatically choose and trace the location of the target iceberg by
comparing the centroid distance histograms (CDHs) of all detected icebergs
in subsequent days with the CDH of the reference target iceberg. Using this
approach, we successfully track iceberg B43 from the Amundsen Sea to the Ross Sea and examine its changes in area, speed, and direction. Three
periods with sudden losses of area (i.e., split-offs) coincide with periods
of low sea ice concentration, warm air temperature, and high waves. This
implies that these variables may be related to mechanisms causing the
split-off of the iceberg. Since the iceberg is generally surrounded by
compacted sea ice, its drift correlates in part with sea ice motion and wind velocity. Given that the bulk of the iceberg is under water (∼30–60 m freeboard and ∼150–400 m thickness), its motion is
predominantly driven by the westward-flowing Antarctic Coastal Current, which dominates the circulation of the region. Considering the complexity of modeling icebergs, there is a demand for a large iceberg database to better understand the behavior of icebergs and their interactions with surrounding environments. The semi-automated iceberg tracking based on the storage capacity and computing power of GEE can be used for this purpose.
Redesigning library orientation for first-year medical students during the pandemic
Authors: Hickner Andy , Wright Drew , Merlo Loretta , Gordon-Elliott Janna S. , Delgado Diana
Published: October 2021

Background: Prior to 2020, library orientation for first-year medical students at Weill Cornell Medicine took the form of an on-site treasure hunt competition. Due to the COVID-19 pandemic, the orientation for the MD class of 2024 was shifted to an all-virtual format. This shift mandated a full redesign of the library orientation.Case Presentation: The Samuel J. Wood Library sought to preserve the excitement and fun of the treasure hunt in the new virtual format. The competition was redesigned as a Zoom meeting using breakout rooms, with library faculty and staff serving as team facilitators. Tasks were rewritten, shifting the focus from the library’s physical spaces to its virtual services and online resources. The redesigned orientation was evaluated using two data sources: a postsession survey of student participants and a debriefing of the library employees who participated. Student evaluations were positive, while the faculty and staff provided numerous suggestions for improving future virtual orientations.Conclusions: A successful virtual library orientation requires careful preparation, including testing the competition tasks, full rehearsal with library facilitators, and a thoughtful approach to technology and logistics. We have chosen to share the materials we developed for other academic health sciences libraries that may wish to take a similar approach to their own virtual orientations.
Nature and Determinants of Educators’ Attitudes toward Teaching Special Needs Learners in a School of Skills
Authors: Rowan Andre , Moletsane Mokgadi
Published: October 2021

This study explored the nature and determinants of educators’ attitudes toward teaching learners with special needs in a rural school of skills that was formerly an ordinary mainstream school. The study adopted a qualitative Grounded Theory approach located within the framework of the constructivist epistemology. Eleven educators (n=11) who were teaching both technical and academic subjects at the school of skills participated in the study. The semi-structured interview was employed as the sole data collection instrument and the coding principles underlying the Constructivist Grounded Theory were used to analyse data. The findings of the study revealed that educators had a positive attitude toward teaching special needs education at the selected school and highlighted the novel factors determining the educators’ attitudes such as both internal and external factors that motivated this positive attitude. The coping strategies identified by the educators replicated those reported in previous research. Palliative and direct coping actions, as well as an integration of these two were also reportedly employed by some participants. It was concluded that the group-based differentiation of the determinants of attitudes may be useful to influence educators’ attitudes at other special needs schools, or those undergoing a similar transitional process.

THE ARMY, SUPERFLUOUS ACTIVITY FROM THE POINT OF VIEW OF ANTHROPOECOLOGY, THAT COULD BE MADE SUSTAINABLE
Authors: Leonel Chacon Anchondo
Published: October 2021

To achieve sustainability, superfluous and negative economic activities must be made productive and positive. From the point of view of Anthropoecology, the army belongs to the superfluous economically active population and the purpose is to make it more sustainable; as well as the common criminals who can be classified in the negative workforce, directing them to a positive activity. Vast majority of soldiers receive training to operate their weapons, maintain great discipline and physical condition. The complex equipment that is currently used (2021 AD.), It is a minority who receive high-level technical instructions for normal army operations, perhaps that training allows them to work in any company or carry out some productive activity for themselves. There is the option of training privates that would like it, in a productive occupation of their choice, before finishing their service in the army, so they don't leave empty-handed and not just like another retiree.

A Metacognitive Instructional Guide to Support Effective Studying Strategies
Authors: Bingham Bailey E. , Coulter Claire , Cottenie Karl , Jacobs Shoshanah R.
Published: October 2021

Metacognition—the processes whereby learners assess and monitor their progress in learning (metacognitive monitoring, MM) and use these judgements of learning to make choices about what to study in the future (metacognitive control, MC)—has been shown to be beneficial to learning. However, effective learning also relies on metacognitive knowledge (MK)—that is, students’ knowledge about effective study strategies and how to employ them. Few students receive explicit in-class instruction on these topics. Here, we explore if an online instructional guide, which includes information about evidence-based study strategies, example questions for self-testing, and a study calendar to help regulate timing of studying can effectively teach MK to improve performance.While it is unclear if the online instructional guide was related to increases in MK, MM, and MC, we did observe benefits to student performance, particularly in highly anxious students on high-stake assessments such as the final examination. Future research should seek to understand how students were engaging with the guide and how the nature of the engagement impacted their study strategies.
Pre-service Teachers’ Perspectives on their Preparation for Inclusive Teaching: Implications for an Organizational Change in Teacher Education
Authors: Massouti Ayman
Published: October 2021

This single case study examined the perspectives of 12 pre-service teachers in one Ontario teacher education program towards their preparation for inclusive teaching using Sensemaking theory as a theoretical framework. Semi-structured interviews as well as document analysis for inclusive education policies were conducted. The findings showed that pre-service teachers perceive inclusion as a collaborative policy practice that requires the possession of a positive mindset, respect towards all learners, and the necessary resources. Moreover, the findings suggest the need for the examined program to critically review its curricular structure in terms of how course designs and requirements would further support future teachers’ knowledge and practices around inclusive teaching. In addition, completing the field-based experience component under the supervision of inclusion-oriented associate teachers and in K-12 classrooms that exemplify students’ diversity was found crucial.
Where is the Support? Learning Support for Multimodal Digital Writing Assignments by Writing Centres in Canadian Higher Education
Authors: Bell Stephanie , Hotson Brian
Published: October 2021

Writing centres play a vital role in supporting all forms of student academic writing in higher education (HE) institutions, including digital writing projects (DWPs)—multiliterate and multimodal, often video-and-audio-based projects, produced using digital technologies. The importance of writing support for multimodal composing is evident in emerging research on both the multi-skilled practices of writer-designers and the conceptual shifts involved in their adoption. Currently, no research exists regarding the Canadian context of writing centre support for DWPs. To address this, we conducted two surveys: one of 22 Canadian writing centres asking about DWPs prevalence, technology and skills readiness, and DWP awareness; and one of faculty at a large Canadian university, asking about DWPs prevalence and frequency and types of DWP assignments. We find a significant disconnect between the number of DWPs being assigned by faculty and the number being supported in writing centres. We also find a significant lack of writing centre preparedness for supporting DWPs. This paper calls, with some urgency, for writing centres to invest in the reality of student writing in Canadian HE, to begin developing instructional materials, equipment, and skilled staff to support DWPs.
Educating Perfinkers: How Cognitive Tools Support Affective Engagement in Teacher Education

Published: October 2021

Our intention is to share our lived experiences as educators of educators employing Imaginative Education (IE) pedagogy. We aim to illuminate IE’s influence on our students’, and our own, affective alertness, and to leave readers feeling the possibility of this pedagogy for teaching and learning. Inspired by the literary and research praxis of métissage (Chambers et al., 2012; Hasebe-Ludt et al., 2009; Hasebe-Ludt et al., 2010), we offer this polyphonic text as a weaving together of our discrete and collective voices as imaginative teacher educators. Our writing reflects a relational process, one that invites us as writers and colleagues to better understand each other and our practices as IE educators (Hasebe-Ludt et al., 2009). It also allows us to share with other practitioners our struggles, questions, and triumphs as we make sense of our individual and collective praxis: how IE’s theory informs our practice, and how our practice informs our understanding of IE’s theory. This text, like IE’s philosophy, invites heterogeneous possibilities.

Published: October 2021

The purpose of this study was to explore the experience and management of stress in science students and to evaluate concordance with faculty/staff members’ appraisal of student stress. A survey was completed by 308 students and by 40 staff and faculty members. Students’ stress levels were high but there were no differences based on demographic groups. Students’ top stressors included workload, grades, career, time management, and anxiety. Faculty and staff members accurately estimated the level of undergraduate student stress but underestimated graduate student stress. They also demonstrated a good understanding of the role of specific academic stressors, but consistently overestimated the contribution of stress from other sources.

Persistent inequities in access to and experiences of learning in postsecondary education have been well documented. In line with efforts to redress these inequities and develop more just institutions, this study explores the potential for pedagogical partnerships in which students and faculty collaborate on teaching and learning initiatives to contribute to classroom equity. We investigate this issue by drawing on qualitative interviews with students who have participated in extracurricular pedagogical partnership programs in institutions in Canada and the United States, and who identify as members of marginalized groups (e.g., racialized students, 2SLGBTQ+ students, students from religious minorities, disabled students). While much existing research on equity and student-faculty partnership primarily focuses on the outcomes of partnership for participating students, we instead investigate students’ perceptions of the extent to which their partnership efforts contributed to wider impacts—such as developments in faculty thinking and teaching practice and student experiences in the classroom. We also consider challenges students noted connected to power imbalances and faculty resistance, which influence partnership’s capacity to contribute to equity and raise important considerations for those interested in partnership practice.
The Intersection between Instructor Expectations and Student Interpretations of Academic Skills

Published: October 2021

Numerous studies exist on how and to what extent course instructors in higher education are embedding or directly teaching writing, learning and information literacy skills in their courses (Cilliers, 2012; Crosthwaite et al., 2006; Mager & Spronken-Smith, 2014). Yet, disparity within the literature demonstrates that there is no consistent approach to the scaffolded development of these necessary skills within courses, programs, disciplines, or across disciplines. This study sought to explore the skills expectations of instructors and whether students are capable of identifying or articulating the academic skills they are required to develop in to succeed in third-year undergraduate university courses. We discovered a discrepancy rate of approximately 63% between instructor and student responses when exploring differences in instructor expectations and student interpretations of academic skills indicated on course outlines. Data from this study suggests that instructors and students do not always share the same understanding of the skills required to complete course work and to be successful in assessments. With the support of learning, writing, and research specialists, instructors can embed academic skill development in the curriculum.
The Perceived Efficacy of Cooperative Group Learning in a Graduate Program
Authors: Janzen Katharine
Published: October 2021

This paper addresses a gap in the literature about the study of the implementation of cooperative/collaborative group learning, and the assessment of its efficacy in facilitating transformative learning in the context of graduate studies. These topics have been widely discussed in the scholarly literature at the K-12 and post-secondary (college and undergraduate) level for many years, and cooperative group learning has generally been found to facilitate student learning. What has not been addressed is the use of this form of group learning in graduate studies. This paper reports on an intentional model of cooperative group-learning used in a Master of Education in Higher Education program at the Ontario Institute for Studies in Higher Education (OISE) at the University of Toronto. A brief review of the literature that grounds this praxis, the elements of the model used, and a post-hoc analysis of the perceptions of 77 graduate students (90% response rate) surveyed in a case study regarding its efficacy in facilitating their learning are presented. The findings suggest that this model of group-based learning has the potential to enhance the process for transformative learning at the graduate level of education.
Collaborative Assessment: Using Self-assessment and Reflection for Student Learning and Program Development
Authors: Flournoy Ellen L. , Bauman Lauren C.
Published: October 2021

As program-level assessment increasingly becomes an integral part of the higher-education landscape, so does the debate regarding the efficacy of current assessment methods. Traditionally, students do not participate in assessment—neither of their own learning nor of institutional or program efficacy. Our assessment process presents an alternative to traditional program-level assessment and is meant to improve student learning in two ways: (1) by asking students to reflect on their achievement of learning outcomes using evidence-based methods; (2) by providing assessment practitioners with authentic, contextualized data on which to make claims about curricula. This collaborative assessment process was designed to address the complex needs of a cross-curricular rhetoric program but responds to many general concerns about traditional assessment methods.
Designing an Indigenous Wellness University Course: A Reflective Case Narrative
Authors: Ferguson Leah , Deschenes Cindy , Bens Susan
Published: October 2021

Postsecondary institutions across Canada have implemented various Indigenization strategies. Critical reflection is needed about the development, implementation, and impact of these strategies to ensure they serve more than checked boxes, and that they strive towards institutional decolonization. The purpose of this article is to present the development of an undergraduate course on Indigenous wellness at a Canadian postsecondary institution. Applying a reflective case narrative scholarly approach, we self-situate to present contextual information about ourselves and the course, as well as our motivation for course development and the scope of curriculum design. We consider five indicators of course design success within Dimitrov and Haque’s (2016) intercultural curriculum design competencies, and we recommend changes to the course design process for Indigenization sake. Reflecting on and interpreting our approach, we propose a three-party relational model to Indigenous course development consisting of the course instructor, a keeper of traditional knowledges, and a teaching and learning expert. In doing so we attempt to inform and prompt the thinking of others with similar or related course design goals.
La correlación entre cuidados y género femenino en las primeras medidas de beneficencia sobre menores del siglo XIX
Authors: Medina Plana Raquel
Published: October 2021

En este análisis de la legislación y los reglamentos relativos a la asistencia a menores se abordan los mecanismos por los que estas prácticas se entendieron como una actividad sexualizada, propia de las mujeres y en tanto que tal, sin valor político. Los textos legislativos trasladan el opacamiento de las tareas realizadas por mujeres en la asistencia a menores, como es el caso de las amas de cría, las Hermanas de la Caridad o las Juntas de Damas, en un contexto político en el que la Beneficencia transitaba hacia un modelo público.
Impact of absenteeism on academic performance under compulsory attendance policies in first to fifth year university students
Authors: Méndez Suárez Mariano , Crespo Tejero Natividad
Published: October 2021

Since the implementation of the European Higher Education Area, universities have been obliged to implement continuous assessment systems that require a high degree of attendance by students. Using recorded data, from year 1 to year 5, of 694 students of a European university, where attendance is mandatory, the main objective of this research is to analyse to what extent absenteeism affects performance across the years of degree study. The investigation found a decreasing effect.  In addition, a cluster analysis was done to find out if the compulsory attendance policy impacts all students equally. Three different behavioural styles were found: those who attend regularly, students who manage their number of absences to comply with attendance rules, who are the real targets the policy, and a third group with a high number of absences not affected by the policy. These findings identify the groups of students who benefit most from adequate attendance.
