Paper

Investigating Levels of Pre-service Teacher Motivation and Confidence to Teach Numeracy.

David Clements

Victoria University, Australia

Presenting Author: Clements, David

In an increasingly complex and uncertain world, proficiency in numeracy skills provides students essential cognitive tools to interpret evidence, evaluate risk and rewards, and make informed decisions. Thus, effective numeracy instruction offers students hope by empowering them with capacities for reasoning and problem solving vital for personal agency and civic participation. This highlights an imperative within teacher education programs worldwide. However, teaching numeracy poses significant challenges for many preservice teachers. Specifically, conceptual ambiguity regarding numeracy presents difficulties for both teacher educators and future teachers across many countries. These difficulties are further compounded by growing attention given to numeracy in educational policies and standards in places like the UK, US, Canada and Australia. These policies increasingly mandate that all subject area teachers take responsibility for teaching numeracy concepts relevant to their disciplines. For example, in the UK, the National Numeracy Strategy instituted a requirement that numeracy be explicitly addressed across all subjects in primary and secondary schools. Similarly, countries like Australia and Canada have introduced standardized literacy and numeracy tests for entrance into many teacher preparation programs. However, international research indicates personal numeracy competence does not necessarily equate to pedagogical expertise in teaching numeracy. Furthermore, pedagogical knowledge alone does not necessarily translate into positive teacher beliefs about their own motivation and self-efficacy to teach numeracy. Extensive previous research reinforces that these affective variables exert significant influence on student numeracy outcomes. This highlights an imperative within teacher education programs worldwide to intertwine building content expertise with efforts to cultivate positive teacher beliefs. Presently, limited data has emerged regarding pre-service teachers’ own motivation and self-efficacy to teach numeracy across different subjects and age groups. Additional perspectives are needed to evaluate teacher educators’ views on best practices for developing pre-service teachers’ beliefs and competencies. Further comparative investigation of the roots of pre-service teachers’ self-beliefs and motivations towards teaching numeracy is therefore vital and could illuminate improvements to initial teacher education involving numeracy curriculum and pedagogy internationally.

The present research examines preservice teachers’ levels of motivation and self-efficacy for teaching numeracy using a mixed methods design. Quantitative findings derived from a newly developed survey instrument demonstrated variability in levels of motivation and self-efficacy beliefs among 729 teacher candidates. Factor analysis indicated that both motivation and self-efficacy to teach numeracy represented valid and reliable factors reflective of Goos’ rich interpretation of numeracy. Subsequent interviews with nine teacher educators yielded qualitative themes such as the significance of previous mathematical education and experience, and the role of teacher educators in fostering critical thinking of pre-service teachers. Integrating the quantitative and qualitative results highlights the need for sustained efforts to understand and improve teacher motivation and self-efficacy to teach numeracy within teacher education. Further research is needed to continue to improve the reliability and validity of the newly developed measure in conjunction with longitudinal and intervention studies. Overall, findings provide additional knowledge to inform ongoing program development and empirical inquiry regarding the field of numeracy teaching within initial teacher education.


Methodology, Methods, Research Instruments or Sources Used
The research design employed in this study can be referred to as a mixed-methods approach, using methods that capture both quantitative and qualitative data. The research design can also be described as a descriptive cross-sectional study rather than an explanatory or experimental one. In this study, data collection through the survey questionnaire and interviews occurred at a single point in time, providing a snapshot of pre-service teacher motivation and confidence levels and the perspectives of teacher educators. This approach does not involve experimental manipulation or intervention, nor does it seek to establish causal relationships or explanations for observed phenomena. Furthermore, the research design emphasizes the measurement and description of pre-service teacher motivation and confidence, rather than attempting to manipulate variables to determine causation. Thus, the study's primary focus is on describing and understanding the current state of pre-service teacher motivation and confidence in numeracy instruction, making it consistent with a descriptive cross-sectional research design.
The research can also be divided into two perspectives. The first perspective was gained through the development and administration of a survey questionnaire designed to measure levels of pre-service teacher motivation and confidence to teach numeracy. The survey instrument was crafted based on a thorough review of relevant literature and subjectd to exploratory and confirmatory factor analysis to ensure validity and reliability. Data collected through the survey provided quantitative insights into the levels of motivation and confidence among pre-service teachers.
The second perspective was developed from qualitative interviews with teacher educators using thematic analysis. These semi-structured interviews were conducted to gain an additional understanding of the nature of and factors that influence pre-service teacher motivation and confidence in teaching numeracy.
The combination of these two research methods—quantitative survey data and qualitative interviews with teacher educators—allowed for a comparative examination of pre-service teacher motivation and confidence in numeracy teaching. By integrating both perspectives, this research design ensures a more robust and nuanced exploration of pre-service teacher motivation and confidence to teach numeracy, contributing to a deeper understanding of this critical aspect of teacher preparation.

Conclusions, Expected Outcomes or Findings
The main contribution of this research has been the development of a new measure of motivation and confidence to teach numeracy. Having been developed through two successive studies, the developed measure achieved very acceptable validity and reliability data. Its factor structure for both the motivation and confidence scales revealed support for a conceptualisation of numeracy teaching in broad alignment with Goos’ 21st century rich model of numeracy. The descriptive data and associations between factors contributed to an understanding of the nature and structure of numeracy teaching. The measure that resulted from the first two studies provided the pre-service teacher perspective. The third study interviewed both mathematics and non-mathematics background teacher educators on their thoughts regarding pre-service teachers’ motivation and confidence to teach numeracy. Again, given the lack of literature on this issue, this research has produced insights helpful for the improvement of Initial Teacher Education (ITE) programs. The resulting themes portray the extent to which teacher educators see their job as developing pre-service teachers’ motivation and confidence to teach numeracy. This also gives voice to what such educators see as problematic and challenging thereby offering suggestions for potential policy or educational initiatives in ITE. The three studies have therefore contributed knowledge to an understanding of pre-service teachers’ levels of motivation and confidence to teach numeracy. Furthermore, when taken together, they form an interesting and perhaps more nuanced and rigorous picture. Important similarities and differences can be seen when comparing the pre-service teacher and teacher educator perspectives. In particular, the importance of mathematics education was highlighted by both. Overall, this research has contributed both conceptually and empirically to the issue of numeracy teaching in ITE and has therefore provided an additional basis from which to articulate future recommendations for research and practice.

Facilitating Compassionate Learning: An Ethnographic Study of Education and Care in Compulsory School for Pupils with Intellectual disabilities in Sweden.

Maria Sjölin, Alexandra Jonasson

University of Gothenburg, Sweden

Presenting Author: Sjölin, Maria

Contribution

Education serves as a key to independence and personal development. In Sweden, children with intellectual disabilities attend a Compulsory School for Pupils with Intellectual disabilities. The education is adapted to the needs of each pupil and aims to provide knowledge, personal development and well-being. There is high staff density with special education teachers and paraprofessionals. Much of the educational practice is conducted by teaching assistants without any formal academic training and there is evidence that communication regarding these teaching and learning processes between teachers and paraprofessionals to be a hurdle. There is limited research that has engaged with the everyday practices within these school settings.

Incorporated within a broader research initiative, this study is conducted within the framework of a larger research project carried out in collaboration between a specialised compulsory school and university: "The path towards collaboration for education in a Compulsory School for Pupils with Intellectual disabilities: in the tension between teaching, care, physiotherapy, and occupational therapy."

The study is grounded in the Sociocognitive theory formation (Bandura, 1977), which emphasizes how learning and knowledge development are influenced by interactions among individuals, their environment, and their own cognitive processes. In the context of Compulsory School for Pupils with severe Intellectual disabilities, the focus will be how teaching and care are shaped and impacted by social and cognitive factors.

The research investigates how teaching and care in Compulsory School for Pupils with severe Intellectual disabilities take shape within the framework of sociocognitive theory. The study will shed light on how teachers and students can interact to create a conducive learning environment and how sociocognitive processes can influence students' well-being and knowledge development.

Within Sociocognitive theory, self-efficacy, also known as confidence or self-capability (Bandura, 1997), is a central concept. Self-efficacy refers to an individual's perceived ability to successfully perform a task within a specific context. In this study, the sociocognitive theory with a focus on self-efficacy will be utilised as the theoretical framework for interpreting the results.

In this study, sociocognitive theory with a focus on self-efficacy will be used as the theoretical framework to interpret the results and describe how self-efficacy, according to sociocognitive theory, can impact teaching and care in Compulsory school for Pupils with severe Intellectual disabilities.

The analysis explores how self-efficacy manifests itself in students and how it affects their engagement, goal setting, and perseverance in the learning process, as well as how teachers' beliefs in students' abilities influence instruction.

The individual's belief in their ability to perform a specific task, according to Bandura's theory of self-efficacy, influences the goals they set and their confidence in achieving them. The level of self-confidence affects how much effort the individual invests in reaching these goals and the degree of persistence when facing challenges (Caprara, G.V., Barbaranelli, C., Steca, P. & Malone, P.S., 2006).

The purpose of the study is to examine the relationship between teaching and care in a Compulsory School for Pupils with Intellectual disabilities. The study describes how teaching and care take place and how these factors can interact to benefit students' knowledge development.

The purpose is further specified in the following research questions:

  • How does teaching occur in Compulsory School for Pupils with severe Intellectual disabilities?

  • How does care take place in Compulsory School for Pupils with severe Intellectual disabilities?

  • How can teaching and care interact to promote students' knowledge development in Compulsory School for Pupils with severe Intellectual disabilities?


Methodology, Methods, Research Instruments or Sources Used
Method

The study adopts an ethnographic approach, aiming to gain a profound understanding of the specific context and intricate dynamics of collaboration between care and teaching and its impact on students' learning. Employing an ethnographic approach in the investigation of teaching and care in Compulsory School for Pupils with Intellectual disabilities involves immersing oneself in the daily environment and culture of the school to comprehend and interpret social interactions and behaviours. The data comprises 50 hours of video observations and field notes documenting educational practices.

Collecting empirical data through video documentation enables a more in-depth analysis of interactions among individuals, groups, and contexts compared to observations solely relying on written documentation (Eidevald, 2022). Conducting observations supported by video technology allows for the study of interaction situations and highlights subtle signals (Andersson and Tvingstedt, 2009; Tanner and Roos, 2017). This study is conducted in an environment where various forms of Augmentative and Alternative Communication (AAC) play a central role in participant interactions. Hence, video documentation is a favorable method for gathering empirical data as it facilitates a detailed examination of teacher and student interactions through both verbal and non-verbal communication (Tanner and Roos, 2017).

To capture details and provide a comprehensive description, video observations were complemented with field notes during all observation sessions. Field notes are a crucial component of data collection in the execution of a condensed ethnographic study.  

 

 

Conclusions, Expected Outcomes or Findings
Expected outcomes

The purpose of the study is to examine the relationship between teaching and care in a Compulsory School for Pupils with Intellectual disabilities. The study describes how teaching and care take place and how these factors can interact to benefit students' knowledge development.

The analysis is based on the empirical data collection methods outlined above. The analysis explores how self-efficacy manifests itself in students and how it affects their engagement, goal setting, and perseverance in the learning process, as well as how teachers' beliefs in students' abilities influence instruction.

The staff's competence in Alternative and Augmentative Communication (AAC) is a direct influencing factor on students' level of participation in education. To enable knowledge development, trust in the abilities of both students and teachers is crucial. By possessing adequate knowledge and skills in AAC, opportunities for increased communicative interaction are created, thereby fostering students' complete engagement and participation in the learning process.

Diffracting Environmental Education in Uncertain Times: A Critical Posthuman and Decolonial Approach to Utopia as Method

Haley Perkins

University of Cambridge, United Kingdom

Presenting Author: Perkins, Haley

While contemporary research affirms we will soon arrive at the point of irreconcilable ecological breakdown, new technologies are advancing rapidly, imbricating themselves into every facet of our lives. Yet today’s mainstream Environmental Education (EE) research lacks thorough exploration of the onto-epistemological origins surrounding how education could/should exist within current entanglements of technology with/in nature. In fact, EE, as positioned in its neoliberal context, driven by a Eurocentric research community, has defaulted to anthropocentric perspectives which force a nature/culture binary (Aikens et al., 2016). What’s more, potentially promising alternative (or ‘transformative’) approaches remain fragmented across EE and are oftentimes inaccessible to teachers.

This paper is thus positioned within the critical current of posthumanism, which brings together critiques of exclusionary, hierarchical, and anthropocentric humanisms from, for example, feminist, decolonial, queer, ecofeminist, STS, and environmental studies (Braidotti, Jones, & Klumbytė, 2022). Critical posthumanism includes decolonial perspectives, which challenge narratives that promote unbridled technological progress by unravelling human/tech, human/nature, and nature/tech binaries and can centre EE within the ever-plural, entangled nature that includes all environments (biological, social, technological), viewing these environments as ontologically and epistemologically entangled (Bozalek & Zembylas, 2017). Critical posthuman onto-epistemologies are particularly relevant to this aim of reconceptualising EE in an ecologically and technologically uncertain world as they stress the hybrid, intersectional, and relational aspects of existence where humans are irreducibly entangled with technology and the environment, co-evolving alongside one another. (Barad, 2007; Braidotti, Jones, & Klumbytė, 2022)

As a result, in my ongoing research as a doctoral scholar, I argue that EE should engage more critically and deeply with envisioning and enacting new ways of being in the world. I propose a reconceptualisation of education that disrupts the constraints of an anthropocentric education system in the Global North, and engages with transformative approaches that do not perpetuate epistemic, social, ecological or technological violence, so we might collectively and effectively help our students navigate the realities of their future and our changing world. I ask: what does living, thriving and dying well on a damaged planet ask from Environmental Education? I draw from the ‘real utopia’ movement within social sciences and humanities research, which formulate concrete proposals to address systemic injustices designed to challenge and transform existing paradigms (Wright, 2010). To do so, this research takes a decolonial approach to Levitas’ (2013) three-staged methodological-philosophical framework ‘Utopia-as-Method’ (UAM) to not only critically analyse the current discourse in EE but also to imagine and construct alternative habits of knowing and being which take into account the technological realities of today’s world.

In this project, UAM’s first stage, Archaeology, involves a critical exploration of current trends, underlying assumptions and metanarratives in EE through a critical hermeneutic literature review, serving as a basis for envisioning transformative alternatives. Stage 2, Ontology, is grounded on an exploration of alternative ways of being and possibilities for the future through decolonial diffractive readings, while Stage 3, Architecture, is where I seek to build alternative EE futures drawing on a research-creation method. This paper will briefly discuss the trends emerging from Stage 1, including, for example, the aforementioned anthropocentric, Western-centric research community, resulting in various instances of colonial modernity and techno-optimism.

The methodological approach of Stage 2 (decolonial diffractive readings) will then be discussed in detail. Having critically considered and unearthed many underlying assumptions and conditions in EE, Stage 2, the Ontology stage of UAM, is grounded on an exploration of alternative ways of being and possibilities for the future, challenging existing ideas and boundaries. Finally, this paper will discuss the implications of these findings on the final UAM Stage within the broader research project.


Methodology, Methods, Research Instruments or Sources Used
The methodological approach for this study will engage with central ideas from the area of Decolonial Research, which is an ontological and socio-political position from which to approach and enact research methodologies (Tuck et al., 2014). Decoloniality in research methods highlights the context in which research problems are conceptualised and their implications and relationship to power, creating different orientations to research (Smith, 2012). The ontological task here is one grounded on decolonial perspectives, informed by critical posthuman (post-qualitative) inquiry, through diffractive reading. This decolonial diffractive approach allows for new insights and unexpected connections that differ from the aforementioned Eurocentric trends I seek to reconceptualize in EE.

Diffractive reading is a departure from normative representational readings toward a reading that embraces a more fluid, relational, and contextually situated approach to inquiry, where multiple perspectives and voices are considered and engaged with (Mazzei, 2014). This approach involves reading one discipline/text/approach with detailed, attentive care through another, allowing them to intersect and influence each other (Fox & Alldred, 2023). In doing so, the material and the discursive become entangled through the diffractive apparatus, producing unpredictable patterns of thought and knowledge (Mazzei, 2014). This approach to reading explores openings for transformative action in EE and observes how they shape each other and/or produce new ideas surrounding what ‘education’ in uncertain times entails. Thus, I will detail my process of thinking with theory, and of deploying concepts to see how they entangle and change/generate thinking.

The findings summarised in Stage 1 will be the luminaries to Stage 2, highlighting what needs further exploration, including discourses not currently (or prominently) featured in EE literature. My diffractive apparatus is built around the notion of defamiliarisation to destabilise colonial norms of knowing and thinking in research and education. I explore seemingly different material-discursive phenomena in relationship with one another and pay attention to the patterns of difference generated. While this research is still ongoing, I anticipate the diffractive readings will engage with pedagogy, Indigenous cosmologies, ecofeminism and deep ecology, AI/technology philosophy, and personal narratives. The aim is to bring these ostensibly different texts in dialogue together to see what emerges. This process includes close readings of the texts followed by diffractive readings and researcher reflexivity using a journal. These journal entries include reflections and memories as a teacher to serve as a bridge from the diffractive process back into education.

Conclusions, Expected Outcomes or Findings
Exploring seemingly different material-discursive phenomena in relationship with one another can generate unpredictable patterns of behaviour. For example, in one diffractive reading within this Stage 2, Ubuntu–a southern African ethic/philosophy (Murove, 2012) was read through Le Guin’s (2019) feminist view of storytelling and technology, The Carrier Bag Theory. In doing so, both Ubuntu and Carrier Bag were made unfamiliar and seen anew in light of the patterns they create, offering insights for understanding technology as a receptacle for togetherness–community, sharing, and communication. This diffractive methodology then brings forth the impetus to question the dominating Eurocentric epistemologies of the Global North, while also examining how technology and human-machine interfaces influence how we perceive and experience. When linked with other diffractive readings on pedagogy and ecology, I expect unique ways of educating in contemporary times to emerge, which this paper will discuss.

As mentioned, EE has been overwhelmingly informed by an anthropocentric philosophical underpinning that promotes an ontological separateness of human/nature/technology with roots in coloniality. As such, this paper aims to interrogate onto-epistemologies often overlooked in mainstream EE, and their potential contributions to teachers’ work around EE in formal contexts of education. Despite the rapid technological advancements and ecological emergencies that define the zeitgeist of contemporary life (Daub, 2020), ontological questions surrounding technology are an area of relative neglect within EE literature. Nevertheless, this type of thinking is necessary for transforming EE. What’s more, many EE scholars call for a new way of being with regard to education and nature (Morrell & Connor, 2002), but do not seem to be able to articulate what a human-nature-technology shift entails. Where traditional EE falls short in its neoliberal, anthropocentric habits, this paper proposes critical posthuman and decolonial methodological approaches can move us into new habits of being and educating in uncertain times.
