Do you spend hours creating word lists and weekly vocabulary tests only to find that your students have forgotten the words by the following week? Janet Allen and her students were frustrated with the same problem. Words, Words, Words: Teaching Vocabulary in Grades 4-12' describes the research that changed the way she and many other teachers teach vocabulary. It offers educators practical, research-based solutions for helping students fall into new language, learn new words, and begin to use those words in their speaking and writing lives. This book offers teachers detailed strategy lessons in the following areas: Activating and building background word knowledge Making word learning meaningful and lasting Building concept knowledge Using word and structural analysis to create meaning Using context as a text support Making reading the heart of vocabulary instructionWords, Words, Words provides educators with a strong research base, detailed classroom-based lessons, and graphic organizers to support the strategy lessons. At a time when teachers are struggling to meet content standards in reading across the curriculum, this book offers some practical solutions for meeting those standards in ways that are meaningful and lasting.

When her reading light goes out, Julie places her chemistry book under her head, passes through a mysterious portal, and finds herself in the land of Science.

"When her reading light goes out, Julie opens a mysterious portal to the land of Science, where she discovers that Tungsten the rogue Periodic has been making trouble" -- T.p. verso.

Lists all the resources needed to create a balanced curriculum for homeschooling--from preschool to high school level.

A collection of poems written in the form of mathematical problems and grouped according to seasonal themes.

The fundamental mathematical tools needed to understand machine learning include linear algebra, analytic geometry, matrix decompositions, vector calculus, optimization, probability and statistics. These topics are traditionally taught in disparate courses, making it hard for data science or computer science students, or professionals, to efficiently learn the mathematics. This self-contained textbook bridges the gap between mathematical and machine learning texts, introducing the mathematical concepts with a minimum of prerequisites. It uses these concepts to derive four central machine learning methods: linear regression, principal component analysis, Gaussian mixture models and support vector machines. For students and others with a mathematical background, these derivations provide a starting point to machine learning texts. For those learning the mathematics for the first time, the methods help build intuition and practical experience with applying mathematical concepts. Every chapter includes worked examples and exercises to test understanding. Programming tutorials are offered on the book's web site.

A groundbreaking introduction to vectors, matrices, and least squares for engineering applications, offering a wealth of practical examples.
