Teachers need to know that the new qualifications will assist them in helping their learners make progress in their lives .  \nWhen these changes were first proposed we were approached by Pearson to join an‘Expert Panel’ that would advise them on the development of the new qualifications. We were chosen, either because of our expertise in the UK education system, or because of our experience in reforming qualifications in other systems around the world as diverse as Singapore, Hong Kong, Australia and a number of countries across Europe.  \nWe have guided Pearson through what we judge to be a rigorous qualification development process that has included:  \n● Extensive international comparability of subject content against the highestperforming jurisdictions in the world  \n● Benchmarking assessments against UK and overseas providers to ensure that they are at the right level of demand  \n● Establishing External Subject Advisory Groups, drawing on independent subjectspecific expertise to challenge and validate our qualifications  \n● Subjecting the final qualifications to scrutiny against the DfE content and Ofqual accreditation criteria in advance of submission .  \nImportantly, we have worked to ensure that the content and learning is future oriented. The design has been guided by what is called an‘Efficacy Framework’, meaning learner outcomes have been at the heart of this development throughout. We understand that ultimately it is excellent teaching that is the key factor to a learner’s success in education . As a result of our work as a panel we are confident that we have supported the development of qualifications that are outstanding for their coherence, thoroughness and attention to detail and can be regarded as representing world-class best practice.”  \nSir Michael Barber (Chair)  \nChief Education Advisor, Pearson plc  \nProfessor Sing Kong Lee  \nDirector, National Institute of Education, Singapore  \nBahram Bekhradnia  \nPresident, Higher","cbCaio1pbdo3FXe7","https://ap.wps.com/l/cbCaio1pbdo3FXe7","pdf",1693718,73,"English","# Introduction\n# Purpose of the specification\n# Qualification aims and objectives\n# Summary of changes (Issue 3)\n## Adjusted font and removed table","[{\"question\":\"When is first teaching and first certification for this Chemistry qualification?\",\"answer\":\"First teaching starts from September 2015, and first certification is from 2016.\"},{\"question\":\"What are the main purposes of the Pearson Edexcel AS Chemistry specification?\",\"answer\":\"It provides evidence of students’ achievements in a robust, internationally comparable post-16 course and enables students to broaden the range of subjects they study.\"},{\"question\":\"What key changes are included in Issue 3 compared with the previous issue?\",\"answer\":\"The specification adjusts the font so symbols for Aluminium, Chlorine and Thallium are clearer, and it removes the table titled “Relation in electronegativity difference”.\"}]","AS Chemistry Specification - Issue 3 | PDF",1792466367,184]
