You see, grandma, we perforate an aperture in the apex, and a corresponding aperture in the base ; and by applying the egg to the lips, and forcibly inhaling the breath, the shell is entirely discharged of its contents. But, I would also hope that experience brings with it the maturity and capacity to allow for some enthusiasm from others. Cotton spinners will sometimes use a distaff, sometimes not, depending on how their cotton was prepared.

When you're telling somebody something they already know well, it's sometimes said that you're "teaching grandma to suck eggs". In 1707, Francisco de Quevedo coined the expression “Teaching your grandmother how to suck eggs”—a colourful reference to the fact that Spanish grannies who’d lost their teeth were adept at sucking eggy goodness through a pinhole in raw eggs. As for the Wikipedia article's surmise that sucking raw eggs was a practice limited to the old and toothless, that notion seems contrary to the historical record, too. The saying still survives despite the fine art dying out in our "civilized" and salmonella fearing culture.

Stevens, of Francisco de Quevedo (Spanish author): "You would have me teach my Grandame to suck Eggs".

b) They are presented or perceived as a complete description of teaching… when, in reality, we know there are other things to think about too. It’s like some people think by challenging others continually, they will raise their online profile – and maybe they will, just doesn’t seem to me that this is for the “right reasons”? I clocked a twitter person recently protesting that, as far as they are concerned, ‘Rosenshine is patronising’.In any case, the Indians don't impute the practice to "old white people" or to "toothless white people" but to "the white people. Even if people are new to hearing about his work, the ideas Rosenshine describes are absolutely not new. We can intellectualise some of the bigger ideas and concepts in education – but classroom dynamics are all about details of speech, tasks, resources, routines. Rosenshine’s principles are, for some teachers, especially in terms of reminding us all about clear communication of new knowledge and strategies. If both sides of the egg-sucking scenario do their bit, we have harmony and can get on with discussing those ideas.

It’s up to us to give our prospects something they’ve never heard before—or never seen in quite the same way. There seems to be some idea, especially online, that it’s better to criticise than to simply let someone have their say – as in “the squeaky wheel makes the most sound? Most likely the meaning of the idiom derives from the fact that before the advent of modern dentistry (and modern dental prostheses) many elderly people (grandparents) had very bad teeth, or no teeth, so that the simplest way for them to eat protein was to poke a pinhole in the shell of a raw egg and suck out the contents; therefore, a grandmother was usually already a practiced expert on sucking eggs and did not need anyone to show her how to do it. These days this proverbial saying has little impact as few people have any direct experience of sucking eggs - grandmothers included. Raw eggs, with or without a little seasoning, used to be a popular food and were regarded as healthy.But give our tribe a new bit of software to evangelise…and excruciating introductory sentences (see above), awash in industry truisms, are a definite possibility. Sucking an egg from a shell that has a single hole in it is likely to be no more efficient than "shooting" a beer from a can that has only one opening in it. Products shown, tagged or featured on YouTube by creators are sold by merchants and are subject to merchant's terms and conditions. I guess my point is that – agreeing again with you, Tom, Rosenshine is making suggestions based on observations of effective teachers and teaching practices. The short-tailed weasel ( Mustela erminea) will put a small hole into an egg and then lap up the contents as they come oozing out.
