Brenda Ruiz, a science teacher, wants her students to understand the makeup of atoms and molecules. She plans to begin with protons, neutrons, and electrons, and use models to identify the protons and neutrons in the nucleus. She then plans to display several models, beginning with simple elements, such as hydrogen and helium, and gradually progress to elements with larger numbers of protons, neutrons, and electrons. Finally, she plans to have the students identify elements on the periodic table. Brenda's thinking in this example best illustrates which of the following?
a. Knowledge of learners and learning
b. A task analysis
c. Teaching to a standard
d. Instructional alignment
Question 2

b. learner accountability.
c. diagnostic assessment.
