glencoe chemistry matter and change: Demystifying Academic Reading Zhihui Fang, 2023-09-29 Foundational and accessible, this book equips pre-service and practicing teachers with the knowledge, understanding, tools, and resources they need to help students in grades 4–12 develop reading proficiencies in four core academic subjects—literature, history, science, and mathematics. Applying a disciplinary literacy approach, Fang describes the verbal and visual resources, expert strategies, inquiry skills, and habits of mind that students must learn in order to read carefully, critically, purposefully, and with an informed skepticism across genres and content areas. He also shows how teachers can promote language learning and reading/literacy development at the same time that they engage students in content area learning. With informative synthesis and research-based recommendations in every chapter, this text prepares teachers to help students develop discipline-specific, as well as discipline-relevant, discursive insights, literacy strategies, and ways of thinking, reasoning, and inquiring that are essential to productive learning across academic subjects. It also provides teacher educators with approaches and strategies for helping teacher candidates develop expertise in academic reading instruction. In so doing, the book demystifies academic reading, revealing what it takes for students to read increasingly complex academic texts with confidence and understanding and for teachers to develop expertise that promotes disciplinary literacy. This state-of-the-art text is ideal for courses on reading/literacy methods and academic literacy and eminently relevant to all educators who want their students to become thoughtful readers and powerful learners |
glencoe chemistry matter and change: Smart Health Andreas Holzinger, Carsten Röcker, Martina Ziefle, 2015-02-24 Prolonged life expectancy along with the increasing complexity of medicine and health services raises health costs worldwide dramatically. Whilst the smart health concept has much potential to support the concept of the emerging P4-medicine (preventive, participatory, predictive, and personalized), such high-tech medicine produces large amounts of high-dimensional, weakly-structured data sets and massive amounts of unstructured information. All these technological approaches along with “big data” are turning the medical sciences into a data-intensive science. To keep pace with the growing amounts of complex data, smart hospital approaches are a commandment of the future, necessitating context aware computing along with advanced interaction paradigms in new physical-digital ecosystems. The very successful synergistic combination of methodologies and approaches from Human-Computer Interaction (HCI) and Knowledge Discovery and Data Mining (KDD) offers ideal conditions for the vision to support human intelligence with machine learning. The papers selected for this volume focus on hot topics in smart health; they discuss open problems and future challenges in order to provide a research agenda to stimulate further research and progress. |
