BSc07 baked cookies and packed them into 1 bottle with 78 cookies and 15 packets with 20 cookies each, with no cookies left over. To find the total cookies baked, add the 78 bottle cookies and 300 packet cookies for a total of 378 cookies baked. With 378 total cookies, there are only two equal ways to pack them: all in the bottle or 18 packets of 20 cookies and 1 packet with 18 cookies. If Dr Yeap eats 7 cookies per day, it will take him 11 days to finish the 78 cookie bottle.

2024.06.01 Introducing a competency framework for languag learning materials ...

http://sandymillin.wordpress.com/iateflwebinar2024 Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error. Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials. This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
