School for sexism

By Deborah Cameron (Oxford University)

      This week, it was announced that schools in England are being issued with new guidelines on combatting sexism and gender stereotyping. This initiative follows research conducted for the Institute of Physics (IoP), which found that most schools took sexism less seriously than other kinds of prejudice and discrimination. […]

      The IoP’s main concern—one it shares with the government, which co-funded the research—is that girls are being deterred from studying science subjects by the sexist attitudes they encounter in school. Language is only one of the issues the report urges schools to tackle. […] But language was the main theme picked up in media reporting on the new guidelines, with many news outlets dramatically proclaiming that children ‘as young as five’ were going to be ‘banned’ from using certain words.

      […] I think we can guess why these newspapers were so keen on the language angle. They’ve known since the heyday of ‘political correctness gone mad’ that nothing stirs up the wrath of Middle England like a story about someone trying to ban words. Never mind that no sane parent permits total free expression for the under-fives […].

      This reporting only underlined the point that sexism isn’t taken as seriously as other forms of prejudice. […] Rather than being outraged by the idea of telling primary school children to watch their words, shouldn’t we be asking why ‘children as young as five’ are using sexist language in the first place?

      We may not want to think that this is happening among children still at primary school, but unfortunately the evidence says it is. […] Girl Guiding UK publishes an annual survey of girls’ attitudes: the 2015 survey, conducted with a sample of nearly 1600 girls and young women aged between 7 and 21, found that in the week before they were questioned, over 80% of respondents had experienced or witnessed some form of sexism, much of which was perpetrated by boys of their own age, and some of which undoubtedly occurred in school. 39% of respondents had been subjected to demeaning comments on their appearance, and 58% had heard comments or jokes belittling women and girls. […]

      By the time they go to secondary school, girls are conscious of this everyday sexism as a factor which restricts their freedom, affecting where they feel they can go, what they feel able to wear and how much they are willing to talk in front of boys. In the Girl Guiding UK survey, a quarter of respondents aged 11-16 reported that they avoided speaking in lessons because of their fear of attracting sexist comments.

      So, the Institute of Physics isn’t just being perverse when it identifies sexist ‘banter’ as a problem that affects girls’ education. It’s to the organization’s credit that it’s saying this shouldn’t be tolerated—and it’s also to its credit that it’s offering practical advice. Its recommendations are sensible, and its report contains many good ideas for teachers to consider. […]

      When the Sunday Times talks about ‘boys and girls cheerfully baiting each other in the playground’, the implication is that we’re dealing with something reciprocal, a ‘battle of the sexes’ in which the two sides are evenly matched. But they’re not evenly matched. What can a girl say to a boy that will make him feel like a commodity, a piece of meat? What popular catchphrase can she fling at him that has the same dismissive force as ‘make me a sandwich’? […]

      The IoP report does not seem to grasp that there is more to sexism than gender stereotyping. It falls back on the liberal argument that stereotyping harms both sexes equally: it’s as bad for the boy who wants to be a ballet dancer as it is for the girl who dreams of becoming an astrophysicist. But sexism doesn’t harm boys and girls equally, just as racism doesn’t harm white people and people of colour equally. It is the ideology of a system based on structural sexual inequality: male dominance and female subordination. You can’t address the problem of gender stereotyping effectively if you don’t acknowledge the larger power structure it is part of.

The Disappearing Honeybee

• Honeybees do more than just make honey. They fly around and pollinate flowers, plants, and trees. Our fruits, nuts, and vegetables rely.....................these pollinators. One third.....................America’s food supply is pollinated.....................the honeybee.

Have you seen or heard a honeybee lately? Bees are mysteriously disappearing in many parts of the world. Most people don’t know about this problem. It is called “colony collapse disorder” (CCD). Some North American beekeepers lost 80% of their hives from 2006-2008. Bees in Italy and Australia are disappearing too.

The disappearance of the honeybee is a serious problem. Can you imagine never eating another blueberry? What about almonds and cherries? Without honeybees food prices will skyrocket. The poorest people always suffer the worst when there is a lack of food.

This problem affects other foods besides fresh produce. Imagine losing your favourite ice cream! Haagen Daaz is a famous ice cream company. Many of their flavours rely on the hard working honeybee. In 2008, Haagen Daaz began raising money for CCD. They also funded a garden at the University of California called The Haven. This garden helps raise awareness about the disappearing honeybee and teaches visitors how to plant for pollinators.

Donating money to research is the most important thing humans can do to save the honeybee. Some scientists blame CCD on climate change. Others think pesticides are killing the bees. Commercial bee migration may also cause CCD. Beekeepers transport their hives from place to place in order to pollinate plants year round.

      There is a danger in paying too much attention to learners’ errors. While errors indeed reveal a system at work, the classroom language teacher can become so preoccupied ________ noticing errors that the correct utterances in the second language go unnoticed. In our observation and analysis of errors – for all that they do reveal about the learner – we must beware of placing too much attention on errors and not lose sight of the value of positive reinforcement of clearly expressed language that is a product of the learner’s progress of development. While the diminishing of errors is an important criterion ______ increasing language proficiency, the ultimate goal of second language learning is the attainment of communicative fluency.

      Another inadequacy in error analysis is an overemphasis on production data. Language is speaking and listening, writing and reading. The comprehension of language is as important as production. It so happens that production lends itself to analysis and thus becomes the prey of researchers, __________ comprehension data is equally important in developing an understanding of the process of SLA.

1. What is an analog-digital converter?

An Analog-Digital Converter (ADC) is a widely used electronic component that converts an analog electric signal (usually a voltage) into a digital representation. The ADCs are at the front-end of any digital circuit that needs to process signals coming from the exterior world. Its schematic symbol is:

The output of a microphone, the voltage at a photodiode or the signal of an accelerometer are examples of analog values that need to be converted so that a microprocessor can work with them.

2. How does the ADC convert a signal?

Many ways have been developed to convert an analog signal, each with its strengths and weaknesses. The choice of the ADC for a given application is usually defined by the requirements you have: if you need speed, use a fast ADC; if you need precision, use an accurate ADC; if you are constrained in space, use a compact ADC.

All ADCs work under the same principle: they need to convert a signal to a certain number of bits N. The sequence of bits represents the number and each bit has the double of the weight of the next, starting from the Most Significant Bit (MSB) up to the Least Significant Bit (LSB). In a nutshell, we want to find the sequence of bits bN−1, bN−2, ..., b0 that represents the analog value Vin as Vin=∑n=0N−1bn2nVref2N.

                                         Knowledge and the library

      It was not until the development of monastic libraries in Europe around 1200 that humanity amassed in a single place what approached the collective wisdom and knowledge of the age. Libraries may be exchanges of information and market places for ideas but they are also the buildings which contain the bulk of human knowledge. Or, at least they were until the electronic digitally stored information revolution of the 1980s.

      Now knowledge is virtually everywhere; it has broken free of the constraint of buildings. Today if you were today to destroy all the world’s libraries, it is unlikely that more than 20% of human knowledge would be lost. Certainly, a large amount of archival material would disappear forever, but a substantial volume of knowledge would survive. If a library is a repository of knowledge, this is now just one of its functions. The library’s prime function is now making that knowledge available and encouraging exchange and reflection upon it.

      Electronic knowledge is nowadays available to everybody – in the home, workplace, airport terminal, school, and so on. The Internet has liberated the library; nevertheless, it has not removed the justification for library facilities.

            Technology in schools: Future changes in classrooms

      Technology has the power to transform how people learn - but walk into some classrooms and you could be forgiven for thinking you were entering a time warp. There will probably be a whiteboard instead of the traditional blackboard, and the children may be using laptops or tablets, but plenty of textbooks, pens and photocopied sheets are still likely.

      The curriculum and theory have changed little since Victorian times, according to the educationalist and author Marc Prensky. "The world needs a new curriculum," he said at the recent Bett show, a conference dedicated to technology in education. Most of the education products on the market are just aids to teach the existing curriculum, he says, based on the false assumption "we need to teach better what we teach today". He feels a whole new core of subjects is needed, focusing on the skills that will equip today's learners for tomorrow's world of work. These include problem-solving, creative thinking and collaboration.

'Flipped' classrooms

      One of the biggest problems with radically changing centuries-old pedagogical methods is that no generation of parents wants their children to be the guinea pigs. Mr Prensky he thinks we have little choice, however: "We are living in an age of accelerating change. We have to experiment and figure out what works."

      "We are at the ground floor of a new world full of imagination, creativity, innovation and digital wisdom. We are going to have to create the education of the future because it doesn't exist anywhere today." He might be wrong there. Change is already afoot to disrupt the traditional classroom. The "flipped" classroom - the idea of inverting traditional teaching methods by delivering instructions online outside of the classroom and using the time in school as the place to do homework - has gained in popularity in US schools. The teacher's role becomes one of a guide, while students watch lectures at home at their own pace, communicating with classmates and teachers online.
