title: A complex act—Teacher educators share their perspectives of practicum assessment

authors: Aspden, Karyn Michelle

subjects: practicum

abstract: Practicum visiting and the assessment of students’ practicum form a significant component of the teacher educator role. Teacher educators are tasked with making judgements regarding the quality of students’ teaching practice, as well as their attributes, dispositions, skills and knowledge, and ultimately their readiness to enter the teaching profession. This paper reports the findings of a doctoral study that examined the assessment of practicum in early childhood initial teacher education and, in particular, the way in which practicum assessment was enacted and experienced by early childhood student teachers, associate teachers, and teacher educators within institutional contexts. The study provides insights into how teacher educators define their role, what they look for and hope for in the assessment process, as well as the challenges faced in making authentic, appropriate and informed assessment decisions. The critical importance of professional judgment within the context of a relational pedagogy is highlighted in response to the complex variables involved in practicum assessment. Implications for future directions in policy and practice related to practicum assessment are proposed.

title: Polylactide composites reinforced with pre-impregnated natural fibre and continuous cellulose yarns for 3D printing applications

authors: Priya Muthe, Lakshmi

subjects: additive manufacturing

abstract: Achieving high-performance 3D printing composite filaments requires addressing challenges related to fibre wetting and uniform fibre/polymer distribution. This study evaluates the effectiveness of solution (solvent-based) and emulsion (water-based) impregnation techniques to enhance fibre wetting in bleached flax yarns by polylactide (PLA). For the first time, continuous viscose yarn composites were also produced using both impregnation techniques. All the composites were carefully characterised throughout each stage of production. Initially, single yarns were impregnated and consolidated to optimise formulations and processing parameters. Solution impregnation resulted in the highest tensile strength (356 MPa) for PLA/bleached flax filaments, while emulsion impregnation yielded the highest tensile strength for PLA/viscose filaments (255 MPa) due to better fibre wetting and fibre distribution. Impregnated single yarns were then combined, with additional polymer added to produce filaments compatible with standard material extrusion 3D printers. Despite a reduction in the mechanical performance of the 3D-printed composites due to additional polymer impregnation, relatively high tensile and bending strengths were achieved, and the Charpy impact strength (&gt;127 kJ/m2) for the viscose-based composite exceeded the reported values for bio-derived fibre reinforced composites. The robust mechanical performance of these filaments offers new opportunities for the large-scale additive manufacturing of structural components from bio-derived and renewable resources.

title: Māori women’s perspectives of leadership and wellbeing

authors: Ruru, Stacey Mariu

subjects: Māori women leadership

abstract: This research sought to understand how Māori women leaders maintain their wellbeing within their leadership roles. Semi-structured interviews acknowledging kaupapa Māori theory (Māori philosophy, framework) principles were used to gather the leadership journeys of five Māori women leaders from academic and business backgrounds across the North Island, New Zealand. Kaupapa Māori principles such as kānohi kitea (greeting, meeting face to face), ako Māori (learning, teaching, reciprocity, cultural pedagogy) and manāki ki te tangata (caring, hosting people) provided a methodological framework to follow during interviews with Māori women leaders. From the interviews, thematic analysis was undertaken and patterns, similarities and differences were uncovered that led to the identification of eight main themes: Humility, collective work, the influence of others, overcoming boundaries, balance between te taha hinengaro (mental or psychological wellbeing) and te taha tinana (physical wellbeing), fostering pathways, quieting the mind, and whānau (family) connections. Secondary analysis further developed and explored the themes using indigenous whakataukī Māori (Māori proverbs), which became the overarching theme and connected the eight themes to the five whakataukī. The study found that balance between te taha hinengaro (the psychological, mental wellbeing dimension) and te taha tinana (the physical dimension) from Te Whare Tapa Whā (the four corners of a house) and Te Wheke (the octopus) Māori wellbeing models supported Māori women leaders’ waiora (health, wellbeing). Central to the success of these Māori women leaders was being connected to whānau and friends, and being influenced by tāmariki (children), tauira (students) and employees. These social connections made Māori women leaders strong and resilient to change and challenges. Māori leadership practices and values such as hūmarie (humility), mana wahine (Māori women’s leadership style), manākitanga (caring) and aroha (compassion, love) contributed to leadership drivers that enhanced Māori women within their leadership roles. Finally, recommendations include enhancing practices such as those that encourage mana (influence, power, and identity), mātauranga Māori (Māori knowledge) and ako Māori for future generations to follow.
