SignWise for Kids reviews a range of products including apps, DVDs, books, and websites that include sign language and deaf-related products designed for children from ages 0-8 and their families. These are included in our reviews.  


The focus of the review is on accuracy and clarity* of sign language. The review covers each section if applicable: 

  • ASL grammar
  • ASL vocabulary  
  • pictures/videos
  • manual alphabet (fingerspelling),
  • storytelling or presentation structures  
  • bilingualism**

*Clarity includes fluency in the production of signs. The reviewers also look at whether or not the background, color, and quality aid or interfere with comprehension.  

**Bilingualism:  the focus is on the accurate translation of both languages (i.e., whether the languages shown are semantically and conceptually accurate, and the concepts presented in English and ASL are similar.)


The reviews will include comments about whether or not the proper representation of deaf people and the community are shown in the product if applicable. Some examples include if the product portrays deaf characters in an appropriate way, use appropriate labels to talk about them, and/or give the community credit instead of appropriating their culture for the product's gain. They are not included in the review score because the main focus of SignWise for Kids is on the quality of sign language in the products.  


For each product, the reviewers share what features the products (e.g., interactive features, subtitles, other languages, worksheets, etc). 


What do the Numbers Mean? 

5 points: The signer is clear and fluent. The flow is good. There are no errors in signing or facial expressions. Simultaneous-Communication (sim-com), speaking and signing, is not used and both languages are presented separately. The concepts expressed through translations are correct (the meaning in sign language matches the text and vice versa).

4 points: There are two or more errors in grammar, vocabulary (e.g., phonological errors), or fingerspelling and/or storytelling components (e.g., role-shifting). There are some concerns about editing or usage, but this does not greatly interfere with comprehension. Illustrations are good.

3 points: There are four or more errors in grammar, vocabulary (e.g., phonological errors), or fingerspelling and/or storytelling components (e.g., role-shifting). Sim-Com is used in some places, but not all the time.

1-2 Points: Do not bother--too many errors to count. Sim-Com is used extensively. The illustrations are not clear and they interfere with comprehension. The language errors are substantial.
