Sizing Up Measurement


Book Description

"The lessons in Sizing Up Measurement: Activities for Grades 3-5 Classrooms focus on length, area, volume, angles, weight, time, and temperature. Each lesson is organized in an accessible, easy-to-use format that includes an overview, a list of materials, a vocabulary list, and step-by-step teaching directions. Students come away from these lessons with a deeper understanding of why and how to measure, and they develop the confidence required to make sense of any situation and the measurement tools involved."--pub. desc.

Actual Size


Book Description

How big is a crocodile? What about a tiger, or the world’s largest spider? Can you imagine a tongue that is two feet long or an eye that’s bigger than your head? Sometimes facts and figures don’t tell the whole story. Sometimes you need to see things for yourself—at their actual size.

Powder Sampling and Particle Size Determination


Book Description

Powder technology is a rapidly expanding technology and nowhere more than in particle characterization. There has been an explosion of new particle measuring techniques in the past ten year particularly in the field of on-line measurement. One of the main aims of this book is to bring the reader up-to-date with current practices. One important area of interest is the improvements in on-line light scattering instruments and the introduction of ultrasonic on-line devices. Another is the introduction of on-line microscopy, which permits shape analysis in conjunction with particle sizing.Schools of powder technology are common in Europe and Japan but the importance of this subject has only recently been recognised in America with the emergence of the Particle Research Centre (PERC) at the University of Florida in Gainsville. - Details all the latest developments in powder technology - Written by established authority on powder technology- A comprehensive text covering all aspects of powder technology and handling of particulate solids including characterization, handling and applications

Book Description

Collects cartoons featuring "Cathy," the heroine for the 1980's single working woman, and dealing with mothers, boyfriends, bosses, and chocolate.




Rethinking Class Size: The complex story of impact on teaching and learning


Book Description

The debate over whether class size matters for teaching and learning is one of the most enduring, and aggressive, in education research. Teachers often insist that small classes benefit their work. But many experts argue that evidence from research shows class size has little impact on pupil outcomes, so does not matter, and this dominant view has informed policymaking internationally. Here, the lead researchers on the world’s biggest study into class size effects present a counter-argument. Through detailed analysis of the complex relations involved in the classroom they reveal the mechanisms that support teachers’ experience, and conclude that class size matters very much indeed. Drawing on 20 years of systematic classroom observations, surveys of practitioners, detailed case studies and extensive reviews of research, Peter Blatchford and Anthony Russell contend that common ways of researching the impact of class size are limited and sometimes misguided. While class size may have no direct effect on pupil outcomes, it has, they say, significant force through interconnections with classroom processes. In describing these connections, the book opens up the everyday world of the classroom and shows that the influence of class size is everywhere. It impacts on teaching, grouping practices and classroom management, the quality of peer relations, tasks given to pupils, and on the time teachers have for marking, assessments and understanding the strengths and challenges for individual pupils. From their analysis, the authors develop a new social pedagogical model of how class size influences work, and identify policy conclusions and implications for teachers and schools.




Catalysis with Supported Size-selected Pt Clusters


Book Description

In his thesis, Florian Schweinberger investigates the influence of the precise size of catalytically active species on reactivity. In order to do this he carries out studies both in UHV and under ambient conditions for supported, size-selected Platium clusters (8-68 atoms). Schweinberger probed the electronic structure, adsorption properties and reactivity of two olefins on surfaces and Pt clusters in the submonolayer range. With adsorbed trichloroethene (TCE) a possible cluster-adsorbate induced change in the electronic structure, and for ethene a low-temperature, size-dependent self-/hydrogenation was observed.In a collaborative approach, Schweinberger and colleagues investigated Pt clusters under ambient pressure conditions. They characterised the clusters at at the local and integral level and tested for temperature stability. Experiments in gas phase ?-reactors and in liquid, as part of a hybrid photocatalytic system, revealed size-dependent reactivity.Overall this thesis is not only of interest for those who want to perform similar experiments but also provides superb scientific insights for researchers in the field.




Confidence Intervals for Proportions and Related Measures of Effect Size


Book Description

Confidence Intervals for Proportions and Related Measures of Effect Size illustrates the use of effect size measures and corresponding confidence intervals as more informative alternatives to the most basic and widely used significance tests. The book provides you with a deep understanding of what happens when these statistical methods are applied
