There's no claim of conspiracy there. It's a pretty set of claims.
1. Feminists claim that females are discriminated against because men are oppressors.
2. Most school teachers are females.
3. Teachers discriminate against females when it comes to "tech" (whatever that is).
4. We seem to have an issue with 1 and 3.
None of those are a vast conspiracy. Of course it's clearly garbage (in addition to being useless) on a number of possible fronts.
That women have been co-opted by the patriarchy is hardly a foreign argument and makes 4 not an issue at all would be one. That feminist claims are irrelevant since it's an issue of data and observation - "feminist agenda" isn't a factor at all (it's not a SJW rant).
This is a pretty damning claim:
Beginning in 2002, the researchers studied three groups of Israeli students from sixth grade through the end of high school. The students were given two exams, one graded by outsiders who did not know their identities and another by teachers who knew their names.
In math, the girls outscored the boys in the exam graded anonymously, but the boys outscored the girls when graded by teachers who knew their names. The effect was not the same for tests on other subjects, like English and Hebrew.
Of course I don't know the details and using "two exams" rather than having the same exam graded twice seems pretty stupid - though that might be the journalist getting it wrong. And Israel is not the US (this isn't physics in which the laws are the same in both places...).
