1. Technological integration strategies in teacher-directed instruction only extend to power-point presentations or using a home or library computer for research. A calculator is one of the main tools in mathematics. I would find it extremely hard to take a math class online with no instruction, its basically a “fend for yourself” type of situation.
2. Scientific labs such as dissection or the mixture of chemicals via test tubes or a bunson burner are impossible to accomplish via virtual instruction. Smells especially cannot be duplicated through a computer.
