Working on formative evaluation

I have been working on my Likert-Type scale for my formative evaluation.  I hope I have developed sound statements.  They include: 

The ID instructions used words that the SPED students could read

The ID plan was attention-getting

The ID plan covered all required materials for notebook organization

The simulation game instructions were easy to follow

The simulation game materials were organized

After following the instructions, the notebooks contained three units

After following the instructions, the notebook was divided into 2 sections:  1 for “notes” and 1 for “other.”
