Oh, those children? Actually they are all mine. We are a homeschooling family you know.
The school at home method is exactly as it sounds. It is a close replication of what you would see in a traditional school setting, except with fewer children (well most of the time, but you know how us homeschoolers love babies). A school at home set up will usually involve a set of boxed curriculum, (Abeka, Bob Jones or even books supplied by the public school system), a highly involved parent teacher who follows a highly scripted teacher manual. Students will usually, though not always, spend 5-6 hours a day completing school work. School work will include worksheets, rote drills, and other methods usually seen in a traditional school day. This type of schooling method will generally follow a traditional school schedule which starts in mid-August in the US and ends in late May early June with June through mid-August being summer vacation. All though the particulars may vary this pretty much sums up the school at home method of homeschooling.
Pros: Highly scripted texts and boxed curriculum can make it less daunting for a new homeschooling parent. The routine of this method can also be appealing. Boxed curriculums are all inclusive. You don't have to worry about piecing it together and the lesson plans are pretty much taken care of. All you need to do is gather supplies.
Cons: From my experience this method is teacher intensive and requires A LOT of parental participation. If you have an independent learner this could be frustrating. Boxed curriculums can be costly and since you are following a schedule set up by the publisher there is little room for deviation. The time required can also be overwhelming for the child. Be sure that if you are considering this method that you don't give your child busy work just for the sake of it. Burn out is a real concern with this method of homeschooling.
