Japanese companies have developed a plastic that can be used to make shopping bags that degrade in seawater to help reduce plastic waste in the oceans. Mitsubishi Chemical Corporation and Kaneka Corporation created functional materials referred to as marine biodegradable plastics drawing on the same mechanism by which microorganisms dissolve garbage in soil.
We use CEFR
As a great ESL teacher you need to be able to adapt your teaching style and presentation of material to suit the student’s level.
The six reference levels used by the Common European Framework of Reference (CEFR) for grading an individual’s language proficiency are A1, A2, B1, B2, C1, C2.
Our suggested levels are just an indication. Teachers should evaluate the suitability of a handout before it is taught in a class. Often, a handout is included in two levels. This is based on variations in the way it can be taught in a lesson. A Handout may be suitable as an introductory lesson for one level and a review for a higher level. The teaching notes may include suggestions on how to teach handouts to mixed level students.
