这是老外口语中的口误，误用一个because从句作了主语。这是语法错误。可以作如下修改：
Tronick believes that the fact that a child isn’t learning from the screen doesn’t mean there’s no value to it—particularly if it gives parents time to have a shower, do housework or simply have a break from their child.
或者：
Tronick believes that although a child may not be learning from the screen, it doesn’t mean there’s no value to it—particularly if it gives parents time to have a shower, do housework or simply have a break from their child.
