i use PEELE i think that really helps , Point, Evidence (maybe a study or a sociologist e.g. Murdoch found through his study that...), Explain (explain it so be like = this meant that families .... ), Link (back to question e.g. as a result this leads to...) Evaluate (however ... could criticise this because..)
It depends on the point you're making- I'd say try to use one sociologist and maybe a couple of sentences explaining their point with evidence, then refute it
I'd say try and follow a 'PEEL' type structure! Point, evidence (include a sociological viewpoint), evaluate/analyse/explain depending on what the question asks and then link back. The link can also be used to connect the two paragraphs together- i.e. 'x suggests that y has a negative effect on pupil success because... but this is not the only factor/explanation' Then start the second paragraph with a link as well :)
