title: Self-assessment: Questioning my classroom practice

authors: Earl Rinehart, (Suzanne) Kerry

abstract: Self-assessment activities have become commonplace in classroom environments. Just like most other primary teachers I use self-assessment activities in my classroom practice with good intentions for encouraging children to consider their own learning and achievement. Looking back, however, I see my use of self-assessment tasks served teacher and teaching purposes above student needs and the longer-term goal of developing self-directed (life-long) learners. In hindsight I believe what I was calling self-assessment could more accurately, and perhaps more helpfully, be defined as short, guided reflections. This paper questions this classroom practice and goes on to question the term ‘self-assessment’ suggesting we examine closely our meaning, purpose and practice of self-assessment in the classroom. This paper concludes with questions for teachers to use in reconsidering self-assessment in their own classroom practice.

title: Sustainable composite fused deposition modelling filament using post-consumer recycled polypropylene

authors: Pickering, Kim L.

abstract: Post-consumer recycled polypropylene (PP) with differing harakeke and hemp fibre contents was used to fabricate a range of 3D printing feedstock filaments. The most successful filaments in terms of tensile properties contained 30 wt % harakeke and had a tensile strength and Young’s modulus of 41 MPa and 3.8 GPa respectively. Comparing these results to those of post-consumer recycled PP filament, showed improvements in tensile strength and Young’s modulus of 77% and 275%. The composite that showed the least shrinkage consisted of 30 wt % harakeke with a shrinkage value of 0.34% corresponding to a net reduction of 84% relative to post-consumer PP.

title: Distributed agent-centric system for indigenous data sovereignty

authors: Noovao, Setephano

subjects: holochain

abstract: The sovereignty of indigenous data is a key issue facing indigenous communities. Holochain, a distributed ledger technology, has the potential to address some of the challenges indigenous communities face with respect to data sovereignty. The purpose of this thesis is to critically evaluate the feasibility of using holochain technology to support indigenous data sovereignty. This paper first explores the literature on holochain technology, examining its underlying architecture and features. The research employs a three-phase design science research methodology, conducting an experiment to explore the integration of a decentralized application, holochain, with a prominent cloud service provider. The first phase concentrates on emulating real data-sharing platforms that may utilize data at its disposal, following the principles of indigenous data sovereignty, where a centralized platform could be hosted on a cloud computing service with multiple services in operation. The second phase involves developing a holochain application guided by the principles of indigenous data sovereignty. The final phase seeks to combine the established centralized platform from the first phase with the outcomes of the holochain application from the second phase to experimentally assess whether both technologies can create a data sovereignty solution that aligns with the needs of indigenous data sovereignty. The results of the experiment will provide a solid foundation for understanding the current state of the field and identifying areas where holochain can potentially offer solutions. Furthermore, the results of our research indicate that holochain shows significant promise in tackling the issue of indigenous data sovereignty, although there are considerable limitations that must be addressed and resolved to achieve improved results.
