Support Secondary school students achieve broad mastery of the curriculum if they are taught with methods appropriate to their learning styles and they devote significant effort to their studies. █████ ██ ████ █████ ███████ ██ ███ ████████ ██ ███ ████████ ██ █ ██████████ █████████ ███████ █████ ████████ ███ ███ █████ ██████ ████ ███████ ███████████ ██ █████ ████████ ███████
Summary
The conclusion is that if broad mastery isn’t achieved, it must be that the students aren’t taught with appropriate methods. As support, the author gives a conditional premise: appropriate methods, combined with significant effort, lead to broad mastery. (Contrapositive: if broad mastery isn’t achieved, there either weren’t appropriate methods or there wasn’t significant effort.)
Missing Connection
The premise says that a lack of broad mastery means one of two things: a lack of appropriate methods or a lack of significant effort. But the conclusion is that broad mastery means one thing only: a lack of appropriate methods.
The conclusion would follow if we assumed that when there’s a lack of significant effort, there must also be a lack of appropriate methods. In that case, no matter what, a lack of broad mastery always means a lack of appropriate methods.
