I am conducting a study comparing two teaching methods using the same students. I will first teach chapter 1 with method A and assess their score and then will teach chapter 2 using method B and assess their score and at the end will compare both scores. which design will it be???
Don't you need to balance the design so that half of participants get method A first & half get method B? Otherwise method is compounded with time.
If the same participants are receiving two different interventions, it would be a cross over design. Since you do not have a control group, it would be named uncontrolled before-after cross-over design. Having said that, I would also suggest you revisit the duration of your teaching strategies and the nature of content being taught.
It is a cross-over study. Under some strong assumptions, you can get some insights.

I would recommend that you consider suggestions by Allen and Anton. As
there may be interaction between the methods and topics and differential carry over effects in other variables that affect learning for example, motivation.
Diseño cruzado, sin embargo, tiene posibles sesgos a considerar por el efecto de arrastre del primer método empleado cuando se aplique el segundo.
اذا كان لديك مجموعة جيده من حيث عدد يمكن تقسيمهم الى مجموعتين واجراء على بعض منهم التجربه باختيارهم بطريقه قرعه او بطريقه الاعداد الزوجيه
It is cross over. I think better you take two separate groups of students having same IQ level and then teach the same contents to both groups using method A for one group & B for other.
