Hi @Than Than Aye

I think you can use a fuzzy multi-criteria / multi-objective decision-making method to analyze the variables and parameters of your problem.

Good luck

Majid Jangizehi Thank you Sir.

I am confusing. When I analyze the reliability of the instrument, the value is minus. Does it make sense? How can I show the reliability coefficient? As my research question, I use separately teacher-centered and child-centered.

I think yes because questionnaire items can be worded 'backward'. For example, both these questions might be used to measure the same underlying construct or hidden cause. However, if we used the same response scale for each participants' responses would cancel out.

Isam Alkhalifawi Thank you . I appreciate your comment. Please can I analyze separately without canceling out? I mean I will have two models for teacher-centered practices and child-centered practices.

Dear Dr Than Than Aye. You can analyze each group separately, however this does not necessarily means exactly reversing your questions. The objectives and scopes may be different.

I would like to say a big YES : see e.g., https://www.oecd.org/berlin/43541655.pdfConference Paper Transformation: From Teacher-Centered to Student-Centered En...

Salman Ajlan Thanks a million for your suggestions. It makes my research.
