Book Description
Over the past few years on-site sanitation has been widely promoted as a solution which can be quickly implemented to address sanitation issues, and it is gaining traction. As such, treatment of the contents emptied from on-site containments has become a pressing issue. While dedicated treatment facilities for this purpose have been advocated, co-treating these wastes in sewage treatment facilities is a promising option, which many countries have implemented or are exploring. This option maximises the utilisation of city infrastructure. In cases where the existing sewage treatment facilities are underutilised, co-treatment presents a ready solution for managing fecal sludge and septage. In spite of co-treatment being a well-known practice in many countries, it remains clouded in uncertainty, especially regarding the technical advisability, and potential risks of co-treating fecal sludge or septage in sewage treatment plants. Planners and decision-makers are often very apprehensive in considering co-treatment. As a result, the opportunity to better utilise available infrastructure for co-treatment of sludge is often being missed. Meanwhile, there are also many cases where co-treatment has been tried, either successfully or otherwise, but it has not been possible to draw conclusions from these, to guide the way forward. This guide book explores some of the basic principles behind sewage treatment, and how it may be impacted by co-treatment of wastes from on-site containments, to try to throw some light on how co-treatment could be considered, in an incremental manner, recognising risks and mitigating them. It is intended to facilitate a better understanding among planners, engineers, decision makers and technical practitioners and to help them evaluate and consider the option of co-treatment.

Book Description
One of the major challenges in the world is to provide clean water and sanitation for all. With 3% fresh water reserves in the earth, there are more than 1 billion people who still lack access to clean drinking water. The declining water quality has not only reduced the life expectancy of humans, but it has also contributed to the deleterious negative impacts on aquatic/marine life, flora, fauna and the ecosystem. However, with rapid technological advancements and the availability of advanced scientific instruments, there has been substantial improvement in the design and operation of water and wastewater treatment systems. Recently, these sustainable eco-technologies have been designed and operated to offer the following advantages: (i) a smaller footprint, (ii) less maintenance, (iii) >99% removal of contaminants, (iv) provides the option for resource recovery, (v) less energy consumption, (vi) minimal use of chemicals, and (vii) less investment and operational costs. This book highlights the technologies used for the removal of pollutants such as dyes, uranium, cyanotoxins, faecal contamination and P/N compounds from water environments, and shows that ecotechnologies are becoming more and more important and playing critical role in removing a wide variety of organic and inorganic pollutants from water. In Focus – a book series that showcases the latest accomplishments in water research. Each book focuses on a specialist area with papers from top experts in the field. It aims to be a vehicle for in-depth understanding and inspire further conversations in the sector.

Book Description
"Every student deserves a great teacher, not by chance, but by design" — Douglas Fisher, Nancy Frey, & John Hattie What if someone slipped you a piece of paper listing the literacy practices that ensure students demonstrate more than a year’s worth of learning for a year spent in school? Would you keep the paper or throw it away? We think you’d keep it. And that’s precisely why acclaimed educators Douglas Fisher, Nancy Frey, and John Hattie wrote Visible Learning for Literacy. They know teachers will want to apply Hattie’s head-turning synthesis of more than 15 years of research involving millions of students, which he used to identify the instructional routines that have the biggest impact on student learning. These practices are "visible" for teachers and students to see, because their purpose has been made clear, they are implemented at the right moment in a student’s learning, and their effect is tangible. Yes, the "aha" moments made visible by design. With their trademark clarity and command of the research, and dozens of classroom scenarios to make it all replicable, these authors apply Hattie’s research, and show you: How to use the right approach at the right time, so that you can more intentionally design classroom experiences that hit the surface, deep, and transfer phases of learning, and more expertly see when a student is ready to dive from surface to deep. Which routines are most effective at specific phases of learning, including word sorts, concept mapping, close reading, annotating, discussion, formative assessment, feedback, collaborative learning, reciprocal teaching, and many more. Why the 8 mind frames for teachers apply so well to curriculum planning and can inspire you to be a change agent in students’ lives—and part of a faculty that embraces the idea that visible teaching is a continual evaluation of one’s impact on student’s learning. "Teachers, it’s time we embrace the evidence, update our classrooms, and impact student learning in wildly positive ways," say Doug, Nancy, and John. So let’s see Visible Learning for Literacy for what it is: the book that renews our teaching and reminds us of our influence, just in time.

Book Description
This open access book describes and reviews the development of the quality control mechanisms and methodologies associated with IEA’s extensive program of educational research. A group of renowned international researchers, directly involved in the design and execution of IEA’s international large-scale assessments (ILSAs), describe the operational and quality control procedures that are employed to address the challenges associated with providing high-quality, comparable data. Throughout the now considerable history of IEA’s international large-scale assessments, establishing the quality of the data has been paramount. Research in the complex multinational context in which IEA studies operate imposes significant burdens and challenges in terms of the methodologies and technologies that have been developed to achieve the stated study goals. The demands of the twin imperatives of validity and reliability must be satisfied in the context of multiple and diverse cultures, languages, orthographies, educational structures, educational histories, and traditions. Readers will learn about IEA’s approach to such challenges, and the methods used to ensure that the quality of the data provided to policymakers and researchers can be trusted. An often neglected area of investigation, namely the consequential validity of ILSAs, is also explored, examining issues related to reporting, dissemination, and impact, including discussion of the limits of interpretation. The final chapters address the question of the influence of ILSAs on policy and reform in education, including a case study from Singapore, a country known for its outstanding levels of achievement, but which nevertheless seeks the means of continual improvement, illustrating best practice use of ILSA data.

Book Description
This unique and ground-breaking book is the result of 15 years research and synthesises over 800 meta-analyses on the influences on achievement in school-aged students. It builds a story about the power of teachers, feedback, and a model of learning and understanding. The research involves many millions of students and represents the largest ever evidence based research into what actually works in schools to improve learning. Areas covered include the influence of the student, home, school, curricula, teacher, and teaching strategies. A model of teaching and learning is developed based on the notion of visible teaching and visible learning. A major message is that what works best for students is similar to what works best for teachers – an attention to setting challenging learning intentions, being clear about what success means, and an attention to learning strategies for developing conceptual understanding about what teachers and students know and understand. Although the current evidence based fad has turned into a debate about test scores, this book is about using evidence to build and defend a model of teaching and learning. A major contribution is a fascinating benchmark/dashboard for comparing many innovations in teaching and schools.

Book Description
Improve student outcomes with collective teacher efficacy. If educators’ realities are filtered through the belief that they can do very little to influence student achievement, then it is likely these beliefs will manifest in their practice. The solution? Collective efficacy (CE)—the belief that, through collective actions, educators can influence student outcomes and increase achievement. Educators with high efficacy show greater effort and persistence, willingness to try new teaching approaches, and attend more closely to struggling students’ needs. This book presents practical strategies and tools for increasing student achievement by sharing: Rationale and sources for establishing CE Conditions and leadership practices for CE to flourish Professional learning structures/protocols

Book Description
This book explores the concept of school belonging in adolescents from a socio-ecological perspective, acknowledging that young people are uniquely connected to a broad network of groups and systems within a school system. Using a socio-ecological framework, it positions belonging as an essential aspect of psychological functioning for which schools offer unique opportunities to improve. It also offers insights into the factors that influence school belonging at the student level during adolescence in educational settings. Taking a socio-ecological perspective and drawing from innovative research methods, the book encourages researchers interested in school leadership to foster students’ sense of belonging by developing their qualities and by changing school systems and processes
