Maximal Saturated Linear Orders
The goal of this dissertation is to prove two theorems related to a question posed by Felix Hausdorff in 1907 regarding pantachies, which are maximal linearly ordered subsets of the space of real-valued sequences partially ordered by eventual domination. Hausdorff's question was as follows: is there a pantachie containing no gaps of order type the first uncountable cardinal?
In Chapter 1, some terminology is defined, and Hausdorff's question about pantachies is explored. Some related work by other mathematicians is examined, both preceding and following Hausdorff's paper. In Chapter 2, relevant definitions and results about forcing, gaps, and saturated linear orders are collected. Chapter 3 contains the complete proof of the first theorem, namely, the consistency of the existence of a saturated Hausdorff pantachie in a model where the continuum hypothesis (CH) fails. Finally, in Chapter 4, a different method is used to prove a stronger result, namely, the consistency of the existence of a saturated Hausdorff pantachie in a model of Martin's Axiom along with the negation of CH. The appendix mentions a few related open questions and some partial answers
Strengthening the Adoption of Learner-Centred Pedagogies in Teacher Education in Uganda through Video-Based Self Reflection & College-Based Mentorship System
The intermittent pedagogical support received by teacher-trainers from the central level makes it
difficult to implement new practices in teacher training institutions in Uganda. This mixed-methods
study investigated teacher-trainersâ perceptions of a pilot pedagogical support system
implemented by college-based mentors. Qualitative and quantitative data were elicited using an
online questionnaire completed by teacher- trainers (n=100) and video-records of interviews with
selected college-based mentors (n=6) who reflected on their own experiences to propose ways
of improving the system. The findings revealed that irrespective of years of experience, teachertrainers
appreciate the contribution of college-based mentors towards the adoption of learnercentred
pedagogy. It also revealed that the opportunity for self-reflection and collegial critique
afforded by video enhanced the practices of the mentees and greatly enriched the mentorship
process. Nonetheless, the teacher-trainers expressed the need to broaden mentorship activities
to include subject-specific pedagogical support
FROM LEMONS TO LEMONADE: STUDENTSâ RESILIENCE WHEN MANAGING CHALLENGE
BACKGROUND
To succeed at university and be prepared for todayâs challenging workplace, students need to develop strong resilience. Students face a number of academic, social and life challenges throughout their studies (Brewer et al, 2019; Ainscough et al, 2018). The disruptions from COVID-19 in Semester 1 of 2020 have undoubtedly exacerbated these challenges, or presented entirely novel ones to manage. This study describes how students demonstrated resilience when responding to such challenges.
METHODS
Biomedical science students (n=200) in their 2nd year of study, were asked how they coped with the impact of the COVID-19 pandemic and what advice they would give themselves for dealing with novel challenges in future.
RESULTS & DISCUSSION
Almost half the students struggled with motivation and the loss of on-campus experiential learning (36%), with a third then advising how they would better manage study in future. Many students also emphasised the importance of balancing health with study (21%), whilst other indicators of resilience (adaptability, positive mindset, seeing the âBig Pictureâ) were identified by 38% of students. While some students focused mainly on academic aspects, others had a broader perspective on managing challenges in the context of life and well-being. Students with the most rounded approach to challenges, might thus be those who have greatest resilience.

THROWN IN THE DEEPER END: FIRST YEAR STUDENTS LEARNING ONLINE
BACKGROUND
First year students experience difficulties adapting to independent learning and managing their time (Richardson et al., 2012; van der Meer et al., 2010). These issues were compounded at the University of Queensland when students transitioned to online learning three weeks into semester 1 2020. This study describes studentsâ insights about themselves as learners during this time.
METHODS
Participants (n=144) were enrolled in a first year anatomy and physiology course. At the end of semester, students were asked to reflect on their learning. Responses were coded using inductive thematic analysis.
RESULTS
When asked what they had discovered about themselves as a learner, students mentioned the importance of motivation (n=53), environment (n=44) and social connections (n=42) for learning. When asked what advice they would give themselves if learning was online again next semester, students wanted to maintain a routine (n=48), improve their time management (n=41), make study plans (n=34), and be more proactive (n=27).
DISCUSSION
Universities are microcosms for learning, and during the pandemic first-year students struggled to replicate this context at home. These results suggest that staff should support their students by helping them plan their learning and encouraging connections with peers and staff.

INVESTIGATING THE SOCIAL CONNECTIONS MADE BY FIRST-YEAR STUDENTS DURING A SEMESTER OF ONLINE LEARNING
BACKGROUND
Social connections with peers and staff are important for student learning and academic success (Krause & Coates, 2008; Peacock, Cowan, Irvine & Williams, 2020). These connections are particularly important for first-year students who are new to university. With the rapid shift to online learning in 2020, many traditional avenues for making social connections were lost. This study investigated how and with whom social connections were made by first-year students, and if these connections correlated with academic success.
METHODS
First-year students (n=145) studying biomedical science answered an open-ended question about how they made social connections during first semester 2020, and with whom. Their responses were coded using thematic analysis.
RESULTS AND DISCUSSION
Most students (97%) made at least one connection with peers and/or staff. Students connected with peers only (61%), staff only (4%) or both peers and staff (32%). Some tools were more frequently reported for connecting with peers (social media) or staff (email). Zoom was useful for both types of connections. Students who connected with both peers and staff had the highest academic achievement. To facilitate more student-staff connections, staff should consider using social media, as students most frequently used this tool to make social connections.

PROFESSIONAL IDENTITY OF BIOMEDICAL SCIENCE STUDENTS: THE INTERPLAY BETWEEN SKILLS, ATTRIBUTES AND SELF-ESTEEM
BACKGROUND
The development of professional skills and attributes allows students to build self-esteem, identify with others and view themselves within a profession (Hunter et al., 2007). However, this can be challenging for those within generalist degrees with a diversity of graduate destinations, such as biomedical science (Panaretos et al., 2019). When students in specialised degrees learn skills and attributes that arenât applicable to their desired career, a disconnect occurs, which impacts professional identity development (Noble et al., 2014). This study examined the relationships between skills, attributes and self-esteem among biomedical science students and how this impacts on professional identity.
METHODS
Second year biomedical science students (n=582) were asked to describe their desired profession, skills and attributes they possessed and needed to develop, and their self-esteem. Consenting studentsâ responses were subjected to inductive thematic analyses (Braun & Clarke, 2006).
RESULTS & DISCUSSION
Students described a variety of desired professions, with medicine being the most common. Students also described many skills and attributes that were needed for those professions. There was a correlation between awareness of skills and attributesâŻand self-esteem, reflecting studentsâ developing strong professional identity. This suggests students with greater awareness are more likely be confident in their chosen career.

Changes in perceived and experienced challenges and learning strategies throughout the second year transition
BACKGROUND
The second year slump is a well-recognised phenomenon affecting studentsâ engagement, performance and transition through university (Wilder, 1993; McBurnie, Campbell & West, 2012). Although Australian studies have identified common causes (Loughlin, Gregory, Harrison & Lodge, 2013; Ainscough, Stewart, Colthorpe & Zimbardi, 2018), relatively less is known about studentsâ perceived and actual challenges, and the dynamic use of strategies whilst transitioning through their 2nd year.
METHODS
Undergraduate 2nd year biomedical science students (n=511) were asked about their goals, anticipated challenges and strategies at the start of 1st semester, then the challenges they experienced and strategies used at the end of semester.
RESULTS & DISCUSSION
Almost all students identified academic goals, most frequently being desired performance (45% of responses) and progressive study to stay on top of content (38%). Students perceived time management (67%), increased content complexity/volume (38%) and balancing work-social-study commitments (20%) as the greatest challenges, which they aimed to overcome largely through planning and organisation strategies. Most experienced perceived challenges, however, often to a greater degree than anticipated. Unexpected challenges were frequently reported, managed by dedicating more time or adopting 1-3 new strategies. Academic resilience through the 2nd year transition may therefore require students to be highly adaptable in their learning approaches
BIOMEDICAL SCIENCE STUDENTSâ CHALLENGES AND STRATEGIES TO UNDERSTANDING FEEDBACK
BACKGROUND
Feedback plays a crucial role in how students learn and develop throughout life (Hattie & Timperley, 2007). Although numerous barriers exist to studentsâ use and engagement with feedback (Winstone et al., 2017), the strategies students use to overcome said barriers for life-long learning are less clearly identified in the literature. This study investigated studentsâ feedback challenges and strategies when learning scientific writing.
METHODS
Second-year biomedical science students (n=358) were asked to identify challenges to understanding and applying feedback, and the strategies they used to overcome them. Responses were coded via inductive thematic analysis.
RESULTS & DISCUSSION
From preliminary data (n=94), 60 students identified challenges relating to either construction of feedback (70% of responses), application of feedback to a task they do not understand (17%), or difficulties with discussing feedback with a tutor (13%). To overcome challenges, dialogue with a tutor was a primary strategy (69% of students), while 19% engaged with scientific literature more and 12% reviewed course resources to aid their use of feedback. Interestingly, 12% of the students with no issues still sought dialogue with their tutor to further understand the feedback. These findings suggest most students identify dialogue as playing an important role in their understanding of feedback.

Biomedical science studentsâ intended graduate destinations
Undergraduate students enrolled in generalist degrees, such as biomedical science, have diverse potential graduate pathways that they may choose to pursue. The aims of this study were to evaluate the intended graduate destinations of students, the reasons they chose to study science and the perceived value of the skills they are acquiring for their intended profession. The participants were second year biomedical science students at the University of Queensland. Their responses to open-ended questions regarding their intentions, choices and perceptions were subjected to thematic analysis. Three-quarters of students mentioned one intended profession, with the remainder mentioning two or more. Overall, they identified 53 different intended graduate destinations in the fields of medicine (69%), research (34%), the science industry (14%) and allied health (8%). As reasons for studying science, students commonly reported their interest in science, the influence of role models and enjoyment or academic success in prior study. Many students, particularly those intent on pursuing medicine, said they planned to use science as a pathway to a postgraduate degree. Importantly, all students perceived that the skills they were acquiring in their degree were highly applicable to their future intended professions
