In astronomy, methods such as direct imaging or interferometry-based techniques (Michelson stellar interferometry for example) are used for observations. A particular advantage of interferometry is that it permits greater spatial resolution compared to direct imaging with a single telescope, which is limited by diffraction owing to the aperture of…

In this organic chemistry laboratory experiment, students are guided through a series of exercises to understand the behavior of compounds during liquid-liquid extraction. Aspects of density, structure, solubility, acid-base theory, and pK[subscript a] are all incorporated into activities that students complete in groups. After using their initial…

A warm and comprehensive child-centered approach to early childhood education "Who Am I in the Lives of Children? An Introduction to Early Childhood Education" reflects a practical, constructivist approach to early childhood education (birth to grade 3) and care programs that is dedicated to the development of the whole child--physical,…

Reflecting recent knowledge and developments in the field, this very practical, easy-to-use guide emphasizes learning how to do case study research--from the first step of deciding whether a case study is the way to go to the last step of verifying and confirming findings before disseminating them. The authors show students how to determine an…

One econometric rule of thumb is that greater dispersion in observations of the independent variable improves estimates of regression coefficients and therefore produces better results, i.e., lower standard errors of the estimates. Nevertheless, students often seem to mistrust precisely the observations that contribute the most to this greater…

The "Handbook of Research Methods in Early Childhood Education" brings together in one source research techniques that researchers can use to collect data for studies that contribute to the knowledge in early childhood education. To conduct valid and reliable studies, researchers need to be knowledgeable about numerous research…

Nearly two-thirds of students require some form of remediation before taking college-level classes, and community colleges have become increasingly important in providing this education. Unfortunately, relatively few students complete the developmental courses required to make a transition to college-level work. Based on a three-year study of over…

Learning to teach is a complex intellectual and adaptive performance act. Student engagement is the cornerstone of effective instruction. Current education reform policies, such as Common Core State Standards (National Governors Association Center for Best Practices & Council of Chief State School Officers, 2010) and Teacher Effectiveness…

Notions of culture, ethnicity and identity are highly political (and also personally meaningful) issues within diasporic communities. Complementary schools are particularly interesting sites in this respect, as they are often set up with an explicit cultural agenda of "preserving" or "maintaining" "traditional" culture and language within…

This timely and accessible text introduces, theorises and practically applies two important concepts which now underpin early years practice: those of "playful learning" and "playful pedagogies". Pat Broadhead and Andy Burt draw upon filmed material, conversations with children, reflection, observation, and parental and staff interviews, in their…

Clear, coherent and trusted, this book is the perfect guide to the main social research methods in use today. The much anticipated Third Edition of Clive Seale's bestselling title further expands its coverage to provide an authoritative introduction to all of the social research methods used to analyze qualitative and quantitative data. Written by…

Do dinosaurs have bellybuttons? This intriguing question launched a journey into inquiry science that captivated a class of four-year-olds for eight months. As students enjoyed dinosaur books, examined dinosaur artifacts, drew pictures, watched videos, and generally immersed themselves in all things dinosaur, the authors built a culture of…

"If protons, quarks, and other elementary particles are too small to be seen, how do scientists know they exist? And if these particles do exist, how can one estimate their size, structure, and or their arrangement in atoms?" These are some of the most frequently asked questions by students who study atomic theory. Atomic structure is an important…

Periodic Table Target, a game for middle school or high school students, familiarizes students with the form of the periodic table and the biological significance of different elements. The Periodic Table Target game board is constructed as a class project, and the game is played to reinforce the content. Students are assigned several elements…

The creative application of low-cost, readily available materials and techniques promotes inclusion and provides accessibility in the classroom and laboratory for students who are blind or have low vision. Difficulties encountered by these students include operation of laboratory equipment, execution of ordinary laboratory procedures, and use of…
