Absolutely! Prismatext books are the perfect way for beginners (A1/A2) to study vocabulary. They are also effective for intermediate learners (B1/B2) looking to brush up.
Prismatext books use a technique called diglot weave to aid in memory retention of new vocabulary. The diglot weave technique, also known as blended language and sandwich stories, has a number of academic studies that verify its efficacy. See our overview here.
