It's easier said than done when it comes to teaching good learning skills. However, by the time your child has reached the preteen age, it should be more apparent which type of learner your child is. As school systems become more populated and teacher-to-student ratios drop, it helps for parents to figure out the type of learner their child is and help her develop her skills.
Different people learn different ways, so try various methods of studying a lesson to determine how your child learns best. She may intake new knowledge best by listening to a lecture, reading the material or practicing the theories. Once you know which method works best, encourage her to use those approaches when studying and completing assignments. In addition, be sure to point out how the concepts and ideas she's studying correlate to the world, and try to make connections to everyday events when possible.
As with everything else, remain positive and attentive to her needs. There is nothing wrong with being one particular type of learner, and recognizing your child's strengths early on will help her throughout her academic career.
