Re: Middle school teachers favor girls when they grade. Gender-biased grading accounts for 21 percent of boys falling behind girls.

Directly accounts for it. You've got to include the positive reinforcement and feedback and so on too.

Studies showed boys were at least subconsciously aware their female teachers would grade them less than girls (they placed lower bets when faced with women teachers), that has to impact motivation and so on.

(source article; https://www.huffingtonpost.co.uk/2012/02/16/female-teachers-give-male_n_1281236.html )

Notably, girls had an inaccurate view of the situation, and believed men would grade them more positively than they did, whereas boys accurately deduced women would grade them lower.

Female teachers mark male pupils more harshly than they do their female students, research has claimed. Additionally, girls tend to believe male teachers will look upon them more favourably than female teaching staff, but men treat all students the same, regardless of gender. The study, released on Thursday, told 1,200 students in 29 schools to place financial bets on who would give them higher grades: external examiners or their teacher. Conducted by professors Amine Ouazad and Lionel Page, for the London School of Economic's Centre for Economic Performance, the report said: Male students tend to bet less [money] when assessed by a female teacher than by an external examiner or by a male teacher. This is consistent with female teachers' grading practices; female teachers give lower grades to male students. Female students bet more when assessed by a male teacher than when assessed by an external examiner or a female teacher. Female students' behavior is not consistent with male teachers' grading practices, since male teachers tend to reward male students more than female students.

This is a good example for showing that women perpetrate sexism in an institutional sense. They are the overwhelming majority of teachers, and notably, men do not share their habit here. Their treatment of the boys is abusive, and stems from a culture of disdain and contempt for boys and men, as well as their high in-group bias, stemming from female chauvinism.

Important to note is that while the boys view on the dynamics of sexism was accurate, the girls wasn't. This is something that continues into adulthood as a result of how the inaccurate and gynocentric feminist narrative on sexism is drilled into us. See the study showing women perceive lack of benevolent sexism in their favor as sexism against themselves. In the school study, the girls expect better grades from men than they are given. I would bet if follow ups were done, they would conclude it was because the man was a sexist, when in reality, it is down to female chauvinism and entitlement not being adhered to. Womens in-group bias is high, and because men are not biased in womens favor too, they perceive that as hostile and unfair. I'd personally argue that high in-group bias is due to feminism and its chauvinistic impacts on our culture and how we view the sexes, women MRAs and those sympathetic to the cause who take the time to critically analyze the ideas they were indoctrinated with and reject them, tend to avoid it.

EDIT:

It's also worth considering whether a profession that is full of women we can empirically and measurably show to be misandrous and sexist, might itself have impacts on the number of men willing to be their co-workers, an argument feminists usually assert based on anecdotes that don't align with data (See STEM and hiring bias in favor of women), but in this case might be more apt and based in verifiable facts about the prevalence of sexism in the people who work in the field.

I had this experience in university as well, particularly in the humanities. Female professors graded me more harshly when first meeting me. Then I would lie and let them know I was trans, and my marks would suddenly improve significantly. Male teachers would generally mark me better initially, and little to no change happened if I lied and told them I was trans.

The only time this pattern didn't seem to hold was with openly feminist male professors. They seemed to follow the female professor model.

Obviously this is just anecdotal, but it was noticeable.

Funnily enough it toughens up the boys who make it and it weakens the girls. Obviously it also discourages some boys.

But of the boys who "make it" it toughen them up because they get used to work harder than the girls.

(PowerWisdomCourage)
They work harder than girls and go on to become men that work harder and earn more than women. Some women then complain and try to pass laws because their mediocre effort isn't rewarded as much or more than someone who has worked harder their entire life.

That's one of the arguments I always make. If person A and B are training for a marathon, and they run the same training runs, only you've burdened person B with 5 lb ankle weights, who do you think is going to run a faster marathon? Which is why most of the "institutionalized discrimination" claims I come across seem wrong. If one group of people is discriminated against, they have a more selective filter than everyone else. That should mean that the ones who make it through tend to be better at whatever it is. But the only cases where we really see that are with Asians in academics and men in many fields.

(soakthenfo)
the same complaints if you've ever been in a relationship. the WANTS never stops. You need to put your feet down and set boundaries. Or you'll be step on and perceive as beta while they find something else to be dissatisfied about. It NEVER stops. Funny how the loudest proponent of this feminist movement are #foreversingle women, parents with only daughters, divorcees.

And the new generation of kids brainwashed in public schools.

So let me get this straight, women try to keep men from graduating high school, getting into college, and getting jobs. Then men proceed to work harder than any woman, get useful degrees, get jobs that pay more, and fight for promotions. How are women equal to men again when they can't even succeed with everything slanted in their favor?

(inferior--female)
Couldn't have said it better myself. There's a reason why men have been in charge for most of history prior to the "politically correct" era.

I definitely saw this happen as a kid (I'm a woman). The top students in my class grade-wise were always girls but when the teachers asked questions in class it was always boys who had the good concise answers! Something's fishy.

So, boys have to work 21* harder, close it down bous, wage gap explained.

/S

This is true at all levels of school, too. I experienced it during my own college career in the 80's - men didn't care for women teachers and there was an noticeable bias in how they interacted with and graded females in their class.

I watched my son experience the same thing all through elementary, high school, and college.

Add in lack of recess to burn off boy's energy, lack of discipline in class, lack of positive male role models within school, and you have a recipe for failure. It's almost as if it's purposely designed to have boys fail.

(CylonGlitch)
Same here. My sons went through the whole thing. So far as one elementary school teacher slipping up during the back to school night. All the students there with their parents, she said to everyone, “I love my girls.” Followed by a ton of glares from the parents of the boys. She stammered, never correcting anything and just continued on.

The primary school education is horrible.

(BlueOrange22)
This sets boys behind from an early age and has life long consequences. And just think how much worse it will get when the SJW generation reaches the age where they become teachers/professors, which is probably happening already. Maybe that's even a part of the increasing rate of the gender gap.

(soakthenfo)
For the exact reason I do homeschooling and promote it for kids, specifically for boys. The entire primary and secondary education is run by women. These female instructors just like how a mother's response to a boy's playful and creative expression as trouble making, a female teacher will interpret and deliver discipline for the same thing. Fortunately at home, there might be balance when both parents are present, but at school where a child spends most of their life, the balance is nonexistent. On top of boys not mentally ready for school at an early age, boys are further disenfranchised and misrepresented in institutions.

I promote homeschool for boys for these reason because the education system is failing boys. Do Not allow your child, nephews, and cousins to fall prey to this.
