Learning by Refraction offers a fresh take on Ignatian pedagogy, curating what's most helpful from the latest education research and consolidating what has been tried and tested. A must-read for all educators, even those who may not know Ignatian pedagogy.

Retinoscopy is an eye exam that determines the refractive error of the eye (long sighted, short sighted, astigmatism). A refraction test indicates the strength of the prescription needed for glasses or contact lenses. The new edition of this book provides a concise overview of clinical refraction. Presented in an easy to read format, it is divided into two main sections. The first part explains basic clinical procedures for routine refraction, beginning with an introduction to instruments and the procedure, followed by aspects of the test for different disorders including myopia (short sightedness), astigmatism, keratoconus and refraction in children. Section two provides in depth discussion on retinoscopy and correct use of the retinoscope. The second edition has been fully revised and updated to explain the latest advances in the field, and is further enhanced by clinical images and figures. Key points Practical guide to clinical refraction and retinoscopy Fully revised and updated second edition Explains basic procedures and instruments for refraction test and refraction in different ophthalmic disorders Previous edition (9789351520634) published in 2014

After an attack on earth, all reflective surfaces become weapons to release monsters, causing a planet-wide ban on mirrors. Despite the danger, the demand rises, and 17-year-old Marty Callahan becomes a distributor in an illegal mirror trade—until he’s caught by the mayor's son, whose slate is far from clean. Both of them are exiled for their crimes to one of the many abandoned cities overrun by fog. But they soon realize their thoughts influence their surroundings and their deepest fears begin to manifest. With fast pacing and riveting characters, this is a book that you’ll finish in one sitting.

Now updated and expanded to cover the latest technologies, this full-color text on clinical refraction uses an easy-to-read format to give optometry students and practitioners all the important information they need. Also covers a wide range of other aspects of the eye exam, including anterior and posterior segment evaluations, contact lens, ocular pharmacology, and visual field analysis. Four new chapters cover wavefront-guided refraction, optical correction with refractive surgeries, prosthetic devices, and patients with ocular pathology. Offer precise, step-by-step how-to's for performing all of the most effective refractive techniques. Presents individualized refractive approaches for the full range of patients, including special patient populations. Contriubtors are internationally recognized, leading authorities in the field. New full-color design with full-color images throughout. Completely updated and expanded to include current technologies. A new chapter on Optical Correction with Refractive Surgeries, including keratoplasty, traditional refractive surgeries (e.g. LASIK and PRK), crystalline lens extraction with and without pseudophakia, the new presbyopic surgery, etc. A new chapter on Wavefront Guided Refraction provides information on the advantages and limitations the Hartmann-Shack Method for objective refraction plus aberrometry and the refraction and the use of in the correction of the eye with spectacles, contact lenses, and refractive surgery. A new chapter on Patients with Ocular Pathology reflects the most current knowledge of patients with ocular pathologies. Provides information on Optical Correction with Prosthetic Devices, including corneal onlays, stromal implants, phakic intraocular lenses, etc. Includes new chapters and/or discussions on such topics as: Aberrations of the Eye, Refractive Consequences of Eye Pathology, Diagnosis and Treatment of Dry Eye, Diagnosis of Pathology of the Anterior Segment, Diagnosis of Glaucoma, and Diagnosis of Pathology of the Posterior Segment. Visual Acuity chapter expanded to include the effect of refractive error on visual acuity and statistics on how much of a change in visual acuity is significant. Objective Refraction, Corneal Topography, and Visual Field Analysis chapters include the addition of new electro-optical and computer techniques and equipment. Chapters on Multifocal Spectacle Lenses and Contact Lenses now cover newer progressive addition lenses and contact lenses that are now on the market. Electrodiagnosis chapter revised to take a more clinical approach.

Fascinating physics facts a young scientist needs to know, from one of the most trusted teams in STEM for children! This kid-friendly introduction to the physics of light covers the basics of solar energy, the electromagnetic spectrum, photon particles, light scattering, and reflection and refraction. Readers will follow along as two children and a cow in a lab coat learn how light works in realistic and imaginative scenarios. With accessible language, grounded examples, and easy, hands-on experiments you can do with household items, David A. Adler explains the basics of how light travels and bends. Anna Raff's bright, humorous illustrations make an intimidating topic easy-- and fun!-- to understand. This colorful picture book is a perfect supplement to lessons on light waves, and a great way to explore the topic at home. Named a finalist for the AAAS/Subaru SB&F Prize for Excellence in Science Books in the Children's category, Light Waves is a must-have book for all self-professed science nerds!

• How do children, individually and collectively, make meanings of their learning experiences? • How can teachers become aware of children’s meaning making on an ongoing basis? • Is it possible and useful to create an integrated theory of student learning? • How can classroom research enhance critical understandings of the situated nature of learning and teaching, while taking into account the systemic and educational policy contexts? • How do differences, such as class, race, culture, gender and sexualities, interact with student learning? • How can teachers respond effectively to the realities of today’s diverse classrooms? • What are the current and emerging issues in classroom research? These are just some of the questions this book grapples with. It pays tribute to Professor Graham Nuthall’s (1935-2004) research contributions - a pioneering and internationally renowned classroom researcher of teaching and learning from New Zealand. It has been written by emerging and experienced classroom researchers from several countries as part of a project aimed at building on and extending Nuthall’s research and promoting the conducting, teaching and supervision of classroom research. The authors engage critically with theoretical, methodological and pedagogical possibilities of their research using Nuthall’s work as a springboard. As a result, all authors make links between theory and practice. Further, several leading international researchers contribute comments on future directions for classroom research and its relevance for teaching and learning. Understanding teaching and Learning: Classroom Research Revisited would be of interest to practicing or prospective teachers and teacher educators, as well as scholars and students of teaching and learning.
