What's New

Version 1.3

Thank you for taking the time to download our photosynthesis app. After a period of extensive testing, we have made a number of changes based on the feedback provided by young English language learners, their teachers and their parents. We have tested this app in a range of different learning contexts, from the classroom to the street and achieved some fantastic results. In some cases, students improved their understanding of the topic by over 40%.

To enhance the learning experience even further, we have made a number of changes to the learning content to ensure that we can meet the learning needs of all young people.

We have:

· Updated images to develop visual literacy skills in the context of photosynthesis and across the curriculum.
· Refined definitions of the keywords based on corpus data to allow learners to build on their prior knowledge of the topic of photosynthesis.
· We have adapted content in the Word Order activity to allow English language learners develop competency in the area of sentence level syntax.

We hope that this app will give Chinese speakers learning the topic of photosynthesis through English, increased self-confidence in their knowledge of the subject.
