The first in a new series about Billy Tibbles and his boisterous family life

Summarizing current research and weaving it into practical instructional strategies that teachers can immediately use with young English language learners (ELLs), this book addresses a major priority for today's primary-grade classrooms. All aspects of effective instruction for ELLs are explored: oral language development and instruction, materials, word study, vocabulary, comprehension, writing, and home-school connections. Assessment is discussed throughout, and is also covered in a separate chapter. The volume is packed with realistic examples, lesson planning ideas, book lists, online resources, and reproducibles. Discussion and reflection questions enhance its utility as a professional development tool or course text.

Statistical Computation for Programmers, Scientists, Quants, Excel Users, and Other Professionals Using the open source R language, you can build powerful statistical models to answer many of your most challenging questions. R has traditionally been difficult for non-statisticians to learn, and most R books assume far too much knowledge to be of help. R for Everyone, Second Edition, is the solution. Drawing on his unsurpassed experience teaching new users, professional data scientist Jared P. Lander has written the perfect tutorial for anyone new to statistical programming and modeling. Organized to make learning easy and intuitive, this guide focuses on the 20 percent of R functionality you’ll need to accomplish 80 percent of modern data tasks. Lander’s self-contained chapters start with the absolute basics, offering extensive hands-on practice and sample code. You’ll download and install R; navigate and use the R environment; master basic program control, data import, manipulation, and visualization; and walk through several essential tests. Then, building on this foundation, you’ll construct several complete models, both linear and nonlinear, and use some data mining techniques. After all this you’ll make your code reproducible with LaTeX, RMarkdown, and Shiny. By the time you’re done, you won’t just know how to write R programs, you’ll be ready to tackle the statistical problems you care about most. Coverage includes Explore R, RStudio, and R packages Use R for math: variable types, vectors, calling functions, and more Exploit data structures, including data.frames, matrices, and lists Read many different types of data Create attractive, intuitive statistical graphics Write user-defined functions Control program flow with if, ifelse, and complex checks Improve program efficiency with group manipulations Combine and reshape multiple datasets Manipulate strings using R’s facilities and regular expressions Create normal, binomial, and Poisson probability distributions Build linear, generalized linear, and nonlinear models Program basic statistics: mean, standard deviation, and t-tests Train machine learning models Assess the quality of models and variable selection Prevent overfitting and perform variable selection, using the Elastic Net and Bayesian methods Analyze univariate and multivariate time series data Group data via K-means and hierarchical clustering Prepare reports, slideshows, and web pages with knitr Display interactive data with RMarkdown and htmlwidgets Implement dashboards with Shiny Build reusable R packages with devtools and Rcpp Register your product at informit.com/register for convenient access to downloads, updates, and corrections as they become available.

This Is Our World, written by Tracey Turner, is a colorful celebration of our planet’s cultural and environmental diversity—an unforgettable journey that brings the people, customs, and wildlife of 20 places around the world vividly to life for young readers. Our guides are children who tell us about the animals, plants, and weather that they encounter; the feasts and festivals they enjoy; and the clothes they wear, the way they learn, the languages they speak, and the sports and games they play. The tour is truly global, as we journey from Australia’s desolate Red Centre to bustling New York City, from the windswept Outer Hebrides to the rock houses of Cappadocia in Turkey, via the Amazon rain forest, the Alaskan wilderness, a floating village in Cambodia, and the remote village of Supai, Arizona. This is both a beautiful gift book and a highly-accessible home reference, sure to foster an interest in the wider world, in travel, in diversity, and in conservation. It teaches us that despite its countless languages, customs, and traditions, it really is a small world after all.
