student+learning+objectives

We read about Mager's way of writing objectives and then rewrote the following objective being careful to use [|action verbs]:

"Understand the structure and function of roots, stems, and leaves."

1. The student correctly (standard) names at least two functions of an identified plant organ (behavior) in a performance of the spoken word (condition).

2. Students will identify and label the parts of three plants at 90% accuracy using photographs.

3. Students will be able to label the structure and function of roots, stems, and leaves on a visual representation that they have drawn of a given plant.

4. Using the website Plants and Their Structures as a model, students will observe a plant under a microscope and label and define eleven of its major organs with 90% accuracy.

Challenges:

Knowing how specific you have to be. Does specificity pre-empt differentiation?
