The size characterization of particles present in the form of agglomerates in images measured by scanning electron microscopy (SEM) requires a powerful image segmentation tool in order to properly define the boundaries of each particle. In this work, we propose to use an algorithm from the deep statistical learning community, the Mask-RCNN, coupled with transfer learning to overcome the problem of generalization of the commonly used image processing methods such as watershed or active contour. Indeed, the adjustment of the parameters of these algorithms is almost systematically necessary and slows down the automation of the processing chain. The Mask-RCNN is adapted here to the case study and we present results obtained on titanium dioxide samples (non-spherical particles) with a level of performance evaluated by different metrics such as the DICE coefficient, which reaches an average value of 0.95 on the test images.

Development Approach

Teacher professional learning occurs across various contexts. Previous studies on teacher learning and changes in practice have focused on either classroom contexts or learning communities outside of school, but have rarely investigated teacher learning across multiple contexts. Investigating teacher learning across the double contexts of classroom and learning community has presented methodological challenges. In response, this paper proposes the suitability of adopting a socio-cultural development framework to further the analytical approach to such challenges. Using the framework, this paper considers the case study of a middle school mathematics teacher who resolved a problem of teaching practice through interacting with other members of the community of practice where they build shared goals and knowledge. This paper contributes to the field by expanding the scope of research on teacher learning across these two contexts, in which problem of practice becomes conceptual resources that the teacher uses in her teaching practice.

Transition Issues

Over the years, ICT has emerged as a platform that is seen to enhance the knowledge and skills of students in mainstream learning environments. A growing number of schools however, now provide a separate alternative enrolment for students with special needs. Although there are valid opinions on what is the best method of educating these students (integration vs. segregation) it has been noted by many researchers that technology can play a major role in the learning process. In this paper, an e-learning paradigm is applied in a holistic manner to a special learning community with the aim of determining an appropriate e-learning model and platform to support curriculum design. The paper focuses on a pilot project at a suburban school for students with special needs. The aims of the project are to observe the level of immersion and engagement and its impact on curriculum outcomes of the group. This research project further investigates the transition issues and approaches for this group and the links and relationships beyond the normal school environment. The project has been funded by the School of Information Systems and the School Community.

What brings a tourist from Italy, a lifelong resident of Harlem and a graduate student from a local university together? Crochet hooks, knitting needles, an assortment of green acrylic yarn and time and space for community craftivism. This case study focuses on crossing boundaries through participatory textile making, making time and space for relationship building in the changing neighbourhood of Harlem and practicing institutional stewardship as a ‘good neighbour’. The Walls-Ortiz Gallery and Center – the arts and research space of City Seminary of New York, an intercultural urban theological learning community – affords an opportunity to explore what happens when lives and stories are stitched together through participatory textile practices. Through the lenses of the EcCoWell learning neighbourhood approach and craftivism, this documentation and reflection of data from collaborative yarn bombing and community quilt-making projects over the past two years provide insights on lessons, challenges and opportunities of these community-oriented practices.
