The British railway system is the oldest in the world. This fascinating book describes the early days in the British railway industry, from the opening of the first public steam inter-city railway line in 1830 and Robert Stephenson's Rocket, through to the glory days of the Flying Scotsman and the expansion of the national rail networks in the 1940s to form British Railways. With a biography of George Stephenson the Father of the Railways and his son Robert, a timeline and Track Facts, this book is a must for anyone with an interest in trains and train travel.

We are working with Cambridge International to gain endorsement for this forthcoming series. Help learners develop essential computing skills with an approach that uses real-life examples, reinforces key vocabulary and provides opportunities to learn, practise and apply throughout. - Encourage learners to become confident in working with information and ideas of their own and those of others with discussion tasks, as well as with What can you do? panels at the end of each unit for self-assessment. - Provide a clear pathway through the learning objectives with Practise tasks in each unit, as well as Go further and Challenge yourself! panels with questions designed to support differentiation. - Recap and activate learners' prior knowledge with Do you remember? activities and introduce new computing skills with Learn and Practise tasks.

Wanneer ’n mens na die naghemel opkyk, sien jy nie net sterre nie. Die swart leegte van die ruimte is deurspek met voorwerpe van elke denkbare vorm en grootte – van enorme brandende sterre tot piepklein stofvlekkies. Hierdie boek verken die geheimenisse van sterre en planete en ontsluit die raaisels van astronomie: die wetenskap van die buitenste ruimte.

Computer science has emerged as a key driver of innovation in the 21st century. Yet preparing teachers to teach computer science or integrate computer science content into K-12 curricula remains an enormous challenge. Recent policy reports have suggested the need to prepare future teachers to teach computer science through pre-service teacher education programs. In order to prepare a generation of teachers who are capable of delivering computer science to students, however, the field must identify research-based examples, pedagogical strategies, and policies that can facilitate changes in teacher knowledge and practices. The purpose of this book is to provide examples that could help guide the design and delivery of effective teacher preparation on the teaching of computer science. This book identifies promising pathways, pedagogical strategies, and policies that will help teacher education faculty and preservice teachers infuse computer science content into their curricula as well as teach stand-alone computing courses. Specifically, the book focuses on pedagogical practices for developing and assessing pre-service teacher knowledge of computer science, course design models for pre-service teachers, and discussion of policies that can support the teaching of computer science. The primary audience of the book is students and faculty in educational technology, educational or cognitive psychology, learning theory, teacher education, curriculum and instruction, computer science, instructional systems, and learning sciences.
