Matt studies the role of instructions in how much intermediate grade level students learn from things that they have read. In his work it is critical that the texts he uses are hard enough for the readers so that they cannot easily remember everything but easy enough so that they can read them independently. Which of the following is the best strategy for Matt to use to assure that his materials are working well?
◦ Conduct a pilot study with a sample of participants from the same population as his study.
◦ Use the readability checker on his computer to make sure the materials are the right grade level.
◦ Consult with fourth grade teachers to get feedback as to their perceptions of the materials.
◦ Do post-hoc analyses to assure that the internal consistency of the instruments was sound.
