Mba Nina, you have given kind of good explanation in your analysis but allow me to give comments to complete your analysis. In your analysis, it's better if you emphasize what is the part that give meaningful learning to students. You also forget to analysis about mode, tenor, and field so that the text makes meaning within the context in a particular situation. Thank you
