AbstractThis qualitative phenomenological research study sought to describe teachers’ understanding of and experiences with AfL, AaL, and AoL when using 21st Century approaches to teaching, learning, and assessment. Purposeful sampling was used to select 4 exemplary Canadian elementary school teachers who had a history of using a professional blog for reflective practice. Data collection methods included elementary school teachers’ professional blogs and semi-structured interviews. Data analysis revealed exemplary elementary school teachers’ understandings and living examples of classroom assessment in a 21st Century context. Results also illustrated how technology-integrated assessment gave students the “power to create” and demonstrate their learning in unprecedented ways and provided teachers with rich assessments of student learning. The study discusses implications for classroom practice and educational research, and offers some initial thoughts on the interactions among the purposes of assessment. The study will be of particular interest to teachers who are interested in improving assessment practices in their classrooms and will provide teacher education programs with insight on how to best prepare teacher candidates for 21st Century education.

Assessment of the Inter-Rater Reliability of the Behavioural Assessment and Treatment Taxonomy (BATT)Awan, Ateeq; Center for Applied Disability StudiesApplied Behaviour Analysis (ABA) is an evidence-based approach for treating a range of behavioural challenges and skill deficits commonly associated with developmental disabilities such as Autism Spectrum Disorder (ASD). ABA-based interventions are typically tailored to the socially significant needs of the individual receiving treatment. This individualized nature of treatment delivery can make it challenging for wide-scale program evaluation within and across different ABA service providers. The Behavioural Assessment and Treatment Taxonomy (BATT) is a tool designed specifically for the purpose of standardizing the documentation of assessment and treatment strategies and enabling systematic evaluation of treatment outcomes. The purpose of this study was to assess the inter-rater reliability of the BATT using a retrospective study design (N = 112). The results demonstrated acceptable level of inter-rater reliability (κ > .80) across a number of target variables, although additional refinement of the BATT coding scheme is still required.
Assessing the Utility of a Video-Based Motion Capture Alternative in the Assessment of Lumbar Spine Planar Angular Joint KinematicsGoncharow, Paul; Applied Health Sciences ProgramMarkerless motion capture is a novel technique to measure human movement kinematics. The purpose of this research is to evaluate the markerless algorithm, DeepLabCut (DLC) against a 3D motion capture system (Vicon Motion Systems Ltd., Oxford, UK) in the analysis of planar spine and elbow flexion-extension movement. Data were acquired concurrently from DLC and Vicon for all movements. A novel DLC model was trained using data derived from a subset of participants (training group). Accuracy and precision were assessed from data derived from the training group as well as in a new set of participants (testing group). Two-way SPM ANOVAs were used to detect significant differences between the training vs. testing sets, capture methods (Vicon vs. DLC), as well as potential higher order interaction effect between these independent variables in the estimation of flexion extension angles and variability. No significant differences were observed in any planar angles, nor were any higher order interactions observed between each motion capture modality and the training vs. testing datasets. Bland Altman plots were also generated to depict the mean bias and level of agreement between DLC and Vicon for both training, and testing datasets. Supplemental analyses, suggest that these results are partially affected by the alignment of each participant’s body segments with respect to each planar reference frame. This research suggests that DLC-derived planar kinematics of both the elbow and lumbar spine are of acceptable accuracy and precision when compared to conventional laboratory gold-standards (Vicon).
