As a former Social Studies MOE teacher i can attest that teachers were never asked or pressured in any way to promote PAP agenda. In fact we did set some Source Based Questions challenging and concluding that ministerial salaries were too high and housing is unaffordable. The HODs approves these, and this is seen in various school papers’ answer keys, much to my bemusement.
However, the textbook itself uses persuasions to convince readers government policy is sound and well planned. My ex colleague openly challenged the NIE lecturer and argued on this point. Nothing happened to him.
Whether the Social Studies teacher promotes the PAP or opposition is up to the individual. I would like to think that in my time in school, i used the very critical thinking skills I was supposed to teach my students to question government policy and not blindly follow the textbook.
