TABLE 3.
Example of items and reliability analysis (Cronbach’s α and McDonald’s ω) on the six subscales based on student data.
| Sample items per domain (α/ω) | Learning climate | Classroom management | Clarity of instruction | Activating teaching | Differentiation | Learning strategies |
| My teacher… | ..treats me with respect. ..answers my question |
..applies clear rules. ..ensures that I pay attention. |
..prepares his/her lesson well. ..explains the purpose of the lesson. |
..involves me in the lesson. ..motivates me. |
..connects to what I know or am capable of. ..knows what I have difficulty with. |
..explains how I need to do things. ..stimulates my thinking. |
