In return for working with him for free, I had requested permission to audiotape our sessions; I wanted to use the transcripts as data sources for a chapter that I had been in vited to write. It so happened that I discovered and read Jean Lave's Cognition in Practice that very summer, which inspired me to read other books on mathe matics in everyday situations. Two years later, while conducting a study with my teacher colleague G. Michael Bowen on eighth-grade students' learning during an open-inquiry ecology unit, I discovered these students' tremendous data analysis skills that appeared to be a function of the deep familiarity with the objects and events that they had studied and mathematized earlier in the unit. I reported my findings in two articles, 'Mathematization of experience in a grade 8 open-inquiry environment: An introduction to the representational practices of science' and 'Where is the context in contextual word problems?: Mathematical practices and products in Grade 8 students' answers to story problems'. I Begin ning with that study, I developed a research agenda that focused on mathemati cal knowing in science and science-related professions. During the early 1990s, I was also interested in the notion of authentic practice as a metaphor for planning school science curriculum.\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9781402013768\"\u003e\u003ch3\u003eSemiotic and Activity-Theoretic Perspectives\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9781402013768","offer_id":39416586371165,"sku":"9781402013768","price":106.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/14c8a9ae-b609-4c4a-a47e-ca2fdf6ed5cd.jpg?v=1782274228","url":"https:\/\/shop.autorenwelt.de\/products\/toward-an-anthropology-of-graphing-semiotic-and-activity-theoretic-perspectives-von-w-m-roth","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
