I'd be interested in the literature that "proves" this claim. I learned English from my earliest and had no problems.
Could it be that PNG kids have been doing poorly because the quality of teaching has decreased over the years? Nowadays, teachers are likely to be absent from school as often as their students. Could it be because the infrastructure necessary to teach the children has not been maintained/upgraded? Try teaching in a classroom when the rain leaks through the roofs.
The bandwagons/fads that you talk about are usually introduced by some idiotic external consultant, usually of a liberal bent. What I am suggesting is we forget this fuddy-duddy idea about teaching kids in tok-ples and start teaching them in English at the onset. Kids have a wonderful ability to easily acquire new languages. Modern ideas are more easily conveyed in English than they are in any of our tokples. What is the tokples word for space station? or meteor? or television even? By resorting to tok-ples teaching you are limiting the ability of our kids to understand the basic items in their modern world and assigning them to a primitive time.
