A reading teacher is testing a new reading program for effectiveness. Half of the 1st grade students will be taught using the new ABC Reading program, and the other half of the students will continue to be taught using the old Hooked on Reading program.

Even though you haven't explicitly asked a question, from the description you provided, we can assume with some certainty you wish to know the kind of design being used by the teacher to find out if the new program is effective. In that case:

Answer:

It is an experimental design.

Explanation:

Experimental design, in educational psychology, refers to the allocation of participants under different conditions with the purpose of finding results. The design used by the reading teacher in the description is the most common way to do it. She divides participants into two different groups, the experimental and the control groups. Change is introduced only to the experimental group so that the results obtained from the two groups can be compared. After some time, the teacher must measure the performance of both groups and compare the results. In case the experimental group performs better, the new reading program will have proved itself effective.
