Elementary preservice teachers’school experiences of mathematics and science have shaped their images of knowing, including what counts as knowledge and what it means to know (in) mathematics and science. In this book, preservice teachers’ voices challenge the hegemony of official everyday narratives relating to these images.
The book is written as a parody of a physical science textbook on the topic of light, presenting a kaleidoscope of elementary preservice teachers’ narratives of knowing (in) mathematics and science. These narratives are tied together by the metaphorical thread of the properties of light, but also held apart by the tensions and contradictions with/in such a critical epistemological exploration. Through a postmodern lens, the only grand narrative that could be imag(in)ed for this text is one in which the personal lived experience narratives of the participants mingle and interweave to create a sort of kaleidoscope of narratives. With each turn of a kaleidoscope, light’s reflection engenders new patterns and emergent designs. The narratives of this research text highlight patterns of exclusion, gendered messages, binary oppositions, and the particle nature and shadowy texture of knowing (in) mathematics and science. The presentation format of the book emphasizes the reflexive and polyphonic nature of the research design, illustrated through layers of spoken text with/in performative text with/in metaphorical text.
The metaphor of a kaleidoscope is an empowering possibility for a critical narrative written to both engage and provoke the reader into imag(in)ing a critical journey toward possibilities for a different “knowing by heart” in mathematics and science and for appreciating lived experience narratives with/in teacher education.

This book shares a collection of novel ways to re-conceptualize and envision the moral imperatives of consumption, thereby providing invigorating insights for future dialogue and intellectual and social action. It privileges a consumer moral leadership imperative, which augments the conventional management imperatives of sustainability, ethics, simplicity and environmental integrity. There are 13 chapters, including first-ever discussions of non-violent consumption, transdisciplinary consumption, consumer moral adulthood, integral informed consumption, conscious and mindful consumption, biomimicry informed consumption, and consumer moral leadership as a new intellectual construct. The book strives to intellectually and philosophically challenge and reframe the act, culture and ideology of consuming. The intent is to foster new hope that leads to differently informed activism and to provocative research, policy, entrepreneurial and educational initiatives that favour the human condition, the collective human family and interconnected integrity. This book strives to move consumers from managing for efficiency to leading for moral efficacy, the ability to use their existing moral capacities to deal with moral challenges in the marketplace. The very core of what it means to be a morally responsible member of the human family is challenged and re-framed through the lens of consumer moral leadership.
