[quote=Anonymous]The problem with programs like this is that it uses a discovery based approach. Kids aren't taught how to solve the problems, instead they are supposed to develop their own understanding.

Many of the lessons are interesting and on one hand some students really enjoy this method of learning. For example, this might work well if you have a background or some understanding of the topic, often acquired due to supplemental outside enrichment. Or some really bright students might really enjoy these lessons.

However, this does NOT work well for the lowest 2/3 of students. There are NO worked examples so that students can look to see how to solve problems. If they are absent, weren't paying attention, didn't understand, having worked examples allows students to go back and understand what is happening. It allows parents to look at the worked examples and help their students.

Even though research has consistently shown direct instruction works better for most students, districts keep going with discovery based math and then wonder why only the top third of students are doing well.

Singapore does amazing in math and if you look at their textbooks and workbooks they ALL use a traditional textbook with worked examples to develop a base then they go on and present more challenging problems. [/quote]
