teaching mixed ability lessons for science

Teaching mixed ability classes is unpopular and against the trend. A team from University College London recently attempted to investigate mixed attainment classes, but found it so uncommon that they were forced to abandon the full trial. Becky Taylor, who led the project, said schools are unwilling to embrace the model, which is perceived as risky and unconventional. Teachers and senior leaders often believe it takes more planning and that “setting” is expected by parents. Students taking undergraduate degree programmes are required to complete Work-Integrated Education (also known as a work integrated learning programme) as part of the curriculum requirement.

Indeed, sets are so deeply rooted in the language and concept of English education that rejecting it is considered rather bold – for maths and science in particular – in stark contrast to other parts of the world. In the excellent Clever Land: the Secrets Behind the Success of the World’s Education Superpowers, Lucy Crehan finds that mixed attainment grouping is common in high achieving educational systems such as Finland, Japan and Canada. There is growing evidence, too, that it may be time for a rethink – setting or streaming can have a negative overall effect on student outcomes for lower and middle attainers.

The science department at Bedales School moved away from setting in 2016. All of our classes, from year nine to year 13, are now mixed attainment. At first, there was much apprehension from colleagues and parents, and we wondered if we were doing the right thing for high attainers; arguably, when making changes like this, some students benefit and others suffer.

But for us the important question was whether more students would benefit as a result, and we agreed that they would. We were also supported by the school to introduce an extra teaching group in each year to make the classes slightly smaller wset hk .

A new toolkit of teaching skills

So how has it gone? A year into our policy of mixed attainment grouping, there are still some teachers who worry that they’re unable to move on to the new content they usually cover with a top set. But ideas are changing about how we ensure that every student is intellectually stimulated. We have evidence from people such as Ian Warwick at London Gifted and Talented showing that learning extra content is not the only way to stretch the most able – in fact it’s just one of 10 strategies, including dialogue between the student and the teacher, opportunities for independent research and self-direction.

A student in a bottom set may actually pick up a concept faster than one in a higher set, but could be limited by a lesson aimed at low attainers

We have also found we don’t need more resources for different groups of students, just an alternative approach. When I taught under a system of setting, I planned different lessons for teaching a top and bottom set the same topic; now I teach the same lessons to both levels.

By ensuring that there’s a mix of group and individual work, closed- and open-ended tasks, and that the pace of lessons is varied, I’m able to identify those who need support based on how they’re performing in that lesson, rather than on a previous test result. A student in a bottom set may actually pick up a concept faster than one in a higher set, particularly in science where we have such a range of skills, but could be limited by the design of a lesson aimed exclusively at low attainers.

In practical terms I’ve shied away from setting tasks with right or wrong answers. This prevents a student getting 100% the first time they try while another student gets 20% – a situation that is likely to reinforce the latter’s pre-existing beliefs about their own intelligence. Instead I use concept cartoons with a variety of answers, where students can identify if a conclusion is true or false in the first instance then explore that idea in different ways depending on their level of understanding. All students should feel involved in the conversation, although individuals may be working on different aspects of the task we’ve set.

It’s been challenging. Building a new toolkit of teaching skills has taken work, and I’ve certainly taught lessons where I’ve felt I haven’t stretched the high fliers or supported the lower attainers, enough. To tackle this, we’ve been working in partnership with English and maths teachers to create ways to differentiate planning for our students. It’s led to some great conversations and an influx of strategies we haven’t used before. In all our science meetings, we now share an idea or resource that’s been tried and tested hifu.

The effect on students has been positive. Science is a diverse subject that requires an immense variety of skills, and no student will always be the best, or the worst. In our mixed attainment groups, we’ve seen some of those students who would normally be in a lower ability set get a confidence boost when they pick up a new idea faster than a student who usually excels.

For those at the top end of the class, we’re stretching and challenging them by increasing the depth, rather than the breadth, of their learning. Instead of adding in extra content for the high fliers, we’re making space for any student to explore the questions covered to a range of depths, depending on how well they are picking up ideas in a particular lesson.

At this stage, demonstrating my hunch that results will improve is tricky. Not only do small cohorts mean that comparing year groups is statistically problematic, but the changes in the specifications have come along at the same time. Yet student performance has ceased to feel like a self-fulfilling prophecy. There is more variety between student results in topic tests, rather than a large gap between results for each set – individual students move up and down depending on how well they have engaged with a particular topic. There’s also much more of a “can do” attitude to learning than I’ve ever seen before, and it’s marvellous.

The efficacy of detoxification

"Oil" is the daily food that people eat, so the use of it is crucial to human health, and if used improperly, it can even cause cancer.

Myth 1: hot cooking

A lot of people like to use high temperature stir fry when stir fry, get used to wait until the oil in the pan smoke to fry a dish, this kind of practice is unscientific.High temperature oil not only damages the nutrition of food, but also produces some peroxides and carcinogens.It is recommended to heat the pot before pouring the oil, then you can fry it, not to wait for the oil to smoke.A glass disposable vape pen cartridge looks extremely fascinating! It has a metallic body, which looks better when a glass cartridge is added to the posterior part! These are similar in size to that of normal cigarettes.

Myth 2: don't eat plant-based cooking oil, or don't eat animal oil

If there is no oil, it can cause vitamin deficiency in the body, and the lack of essential fatty acids, which can affect the health of the human body.The emphasis on eating only vegetable oil, not animal oil, is also not good.At a certain dose, animal oil (saturated fatty acids) is beneficial to the human body.

Myth 3: eat only one type of oil for a long time

Now, Fried average household is difficult to do with what kind of food oil, but several we recommend best match alternately edible oil, or for a period of time in a kind of oil, the next period of time in another oil, because there are few a oil can solve the problem of all oil needs.

Myth 4: people with abnormal blood lipids, or people who are not normal weight, do not have a different kind of oil

For people with abnormal blood lipids or abnormal body weight, we are more focused on high monounsaturated fats in vegetable oils.In the quantity of oil, also control.People with blood lipid and body weight should be controlled at least 25 grams per day, and polyunsaturated fatty acids and monounsaturated fatty acids are almost evenly split.And the crowd that the elderly, dyslipidemia, obesity crowd, the crowd obesity related diseases or have a family history of obesity crowd, they each use the oil to lower every day, even down to 20 grams.

Families warned they may lose children's health coverage

Families warned they may lose children's health coverage
State officials in Virginia started warning families this week that the popular Children’s Health Insurance Program (CHIP) is about to run out of money.Plan a unique hong kong tour for your clients with PartnerNet's useful travel tips, and various tourist information such as Chinese customs and traditions.
It’s one of several states that have given notice or are preparing to tell families that funding for the program has ended and Congress has failed to renew it.
For many families, that could mean an end to their health care unless they find someone to offer free care to their kids, according to Linda Nablo, chief deputy director at Virginia's Department of Medical Assistance Services.
“I would say most families, their children will go without insurance,” Nablo said.
CHIP is a joint state-federal health insurance plan for low-income kids who don’t have health insurance any other way. Funding varies from state to state but most of the money comes from the federal government.
Federal funding for the program ran out in September and Congress has failed to renew it. The continuing resolution passed last week keeps the federal government open for business until December 22 and it included a patch for CHIP, but that was just to move money from

states that have not yet run out of cash to states whose CHIP programs were about to go broke.

Virginia’s program, known as FAMIS (Family Access to Medical Insurance Security), runs out of money in February.
“We are hopeful that Congress will once again provide the funding to continue this program. However, because Congress has not acted yet, we need to let you know that there is a chance the FAMIS programs may have to shut down,” the Virginia letter reads.
“We think of it as an informational letter,” Nablo added. “We are trying to give families information if they need to do something for their child. We are trying to give them as much time as we can to understand what’s going on, ask their questions, make whatever decisions they have to make and prepare to what extent they can.”
“If you have got a medical situation — if your child has cancer, or is in the middle of chemo or is in the hospital or needs surgery, I’d want to know as soon as possible.”
Families should get in any medical visits they can, while they can, the letter advises them.
“If any FAMIS members need medical or dental care, make an appointment to visit your doctor or dentist before January 31,” it suggests. Putting emphasis on quality learning and teaching together with knowledge transfer, PolyU firmly believes that research study is a significant component of academic life on university campus.

“So if your child’s healthy and they don’t need a doctor’s visit or a dentist visit anytime soon then hopefully this letter is just information for you,” Nablo said.
“It is truly shameful that gridlock and dysfunction in Congress have left nearly 70,000 Virginians who depend on the FAMIS program hanging in limbo,”Va. Governor Terry McAuliffe, a Democrat, said in a statement.
Other families may need to act now. If they want to sign up for health insurance on the Affordable Care Act exchange, for instance, they have until December 15 to do so.
Some may need to investigate free or subsidized clinics.
“If you have got a medical situation — if your child has cancer, or is in the middle of chemo or is in the hospital or needs surgery — I’d want to know as soon as possible, and be talking to people about what might be possible,” Nablo said.
The hangup in funding CHIP is partly over how to pay for the it. Republicans and Democrats disagree on whether to cut other programs. But it’s also a casualty of confusion, says Wisconsin Democratic Rep. Mark Potan.
“Congress can’t walk or chew gum on its own or at the same time,” Potan told NBC News. “People look at this and they think Congress is a big old cluster and that these guys can’t govern and they’re right.”

Enerica Rodriguez of Dallas is watching what happens anxiously. She’s got a 13-year-old son with ADHD and a 10-year-old daughter with eczema. Both have asthma, too, and she estimates their monthly medical costs run $800.
“The asthma inhaler and the treatment, they are pretty expensive too.” said Rodriguez. “Without CHIP, I wouldn’t be able to take my daughter to the dermatologist.”
Rodriguez, who works at a dry cleaner, and her husband, a painter, buy coverage on an Affordable Care Act exchange but say adding their children to the plan would be prohibitively expensive. “It wouldn’t cover their medications,” she said.
“Congress can’t walk or chew gum on its own or at the same time.”

Their 21-year-old son is already on his own, Rodriguez said. “We just work hard to provide our income and to have a decent living. We aren’t rich people,” she said. “By them taking away CHIP, it’s going to be very hard.”
Tommie Ogletree of Lewisville, Texas, depends on CHIP to cover two of her three children. She is hoping Congress will pay for the program, which covers 9 million children nationally.
“I would lose everything,” she said. “We cannot afford to give them private insurance. It’s just not feasible for us. Everything is so expensive in the health care industry,” she added.

Her son Bradley, 10, must carry an EpiPen because of a deadly allergy to bee stings.
“With one EpiPen it costs $500. But because we have CHIP it costs $35 for my son’s EpiPen,” Ogletree said LPG M6.
“We don’t have to worry about what other bills are going to come in because of CHIP.”
Other states will send letters soon to families. Connecticut plans to start mailing letters December 15th, according to David Dearborn of the Connecticut Department of Social Services. Utah will send one at the end of December a Department of Health spokesman said.
Twelve governors from both parties wrote Congress on Monday urging it to act.
“Since its creation, CHIP has enjoyed strong bipartisan support,” they wrote.
“We encourage you to work across the aisle to find common ground that will allow this important program to continue and give the families who rely on CHIP the peace of mind of knowing that their children will be able to get the health care they need in the new year.”

spring Onions and wine

Before and after the cold dew, the air is drier and the "autumn dryness" is vulnerable. Nutrition experts caution, to stay away from "autumn dryness", the public should drink honey water and salt water less spicy food.boutique hotel hongkong (GDHK) is located in the centre of Tsim Sha Tsui which is surrounded by streets of boutiques, vast variety of restaurants & famous shopping malls, such as i-Square, K11 &The One.  

After the cold dew, the cold air in the north has a certain influence. Most of China is under the control of cold and high pressure, the rainy season is over and the weather is dry. The first affiliated hospital of tianjin medical university nutrition experts say, drink plain boiled water is a good method, but if you want to completely resist "autumn dry" the negative effect, had better add some salt in water or honey. At the same time, be careful not to eat or eat spicy barbecue food, such as chili, prickly ash, cinnamon, ginger, spring Onions and wine.

As the weather turned cold this week, the sunny weather that accompanied our long vacation was gone. The new week begins and today is the "cold dew" of the 24 solar terms. As the saying goes: "cold feet don't show, from now on, must pay attention to keep warm, especially feet, in case" cold from the foot ".

"Cold dew" is the earliest "cold" generation in the 24 solar terms, and its emergence proves that the winter is near. Compared with the "white dew" of a month ago, the temperature is lower now, the dew is more, but with a very strong chill. The wild goose south flies, the leaves fade yellow, the cold dew once, the weather is cold to turn cold, sooner or later is the cold wind to the bone, the temperature is lower, need to always be careful to add clothing clinique fresh pressed.

Eat more warm products in the diet, such as chestnut, pear, water chestnut, water chestnut, grapefruit, etc. Try to eat less spicy, smoked, and cold fruits like watermelon and bitter melon.

Being depressed and having a tantrum

An aging population has led to an increase in the number of people with dementia in South Korea, the chosun ilbo newspaper reported on November 17. The number of people with dementia in South Korea in 2011 was about 295,000, or about 459,000 in 2015, an annual increase of 11.7%, according to the Korea health insurance review and evaluation institute.The best way to reduce labour in refilling vape cartridge is by getting an oil cartridge filling machine! They have a small table top design and come with a year’s warranty. So, do some work with this machine!

If you develop dementia, early medical treatment can help to prevent the disease from worsening. If there are three symptoms, seek early medical attention to check for dementia.

1. Being depressed and having a tantrum
Sudden mood depression, emotional ups and downs, need to be alert for signs of dementia. Early cognitive decline in dementia, easy to get out of control, so there is no interest in anything, listlessness and other depressive symptoms. Even without depression, personality is different. If you are upset about something that you didn't feel before, you can only wonder if you have dementia.

2. There are diagonal lines on the earlobes
The appearance of a diagonal line in the lobe indicates a risk of dementia. A recent study by South Korea's qingxi medical institute and samsung medical college found that people with wrinkles in their ears were twice as likely to develop dementia as those without wrinkles. Experts speculate that this is because the capillaries in the earlobes produce wrinkles, while wrinkles reflect the health of the blood vessels. In addition, earlobe wrinkles are linked to heart disease. The American internal medicine yearbook study found that 78.8% of the 241 patients hospitalized with acute stroke had wrinkles in their earlobes.

3. Memory loss, getting lost and forgetting words
If memory is significantly reduced compared with previous years, it may be a mild cognitive impairment prior to dementia. If memory decreases, but does not interfere with daily life, it is pure amnesia, or forget the things that often do, repeatedly make mistakes, need to be alert for dementia. Amnesiacs can be aware of their memory loss, but patients with dementia are completely unaware of their memory loss and their memory loss. In fact, people with mild cognitive impairment were 10 times more likely to develop dementia than the normal elderly.

時代變了,環境變了,你我都變了

午夜涼風習習散落點點悲傷,牆角那樹桂花緒香迎滿整個庭院,一草一鳴一孤盞。時光如流水匆匆,一紙思念抹不去。花開在春,衰謝於秋,來來往往,滴滴落落,回憶總是易被歲月風沙摧毀於迂迴長廊。

英國當代著名詩人,西里格夫。薩松說過:我心有猛虎,細嗅薔薇花。第一次眼前掠過這句話時,心不由得微微一顫。開始站在不同角度去,尋思悟解。一個處於孤獨內心情感久了的人,內心一定很強大,但看似無謂的尖鋒下,必定遮躲一顆歷經滄桑磨難平淡如水之心。擁擠人潮中,有多少人習慣把悲傷脆弱焚燒,在世人面前,微笑著呈現不屈不饒。

最近無意邂逅倉央嘉措,這個流浪在拉薩街頭最美的情郎。查閱有關他的歷史記載,情感也跟隨他跌宕起伏的人生,一起一落。今世之路,何時何地發生什麼,似乎冥冥之中早已安排。那個時代政治鬥爭,囚禁傀儡之城的無望生活,只能讓他蜷縮於角落,靠著筆墨竹卷,把情愫執筆於文字,自己對話談心。陌上花開緩緩歸,樂詩裡面記憶猶新的《病婦行》,《孤兒行》也是把主角摧殘人生經歷刻畫的栩栩如生,這不經讓我感嘆,華夏五千年歷史長河,總會有那麼多人,在那麼個點,成為那個時代政局蕩漾,民間背影的產物。

窗外黑云壓城,樹枝狂躁舞動,無痕風聲,撥撩沉睡心境。萬家燈火,淨明相照。凝神許久,每盞燈下,永遠有一個續寫不盡,道不清的故事,在埋綻。斜眼欲穿角落,異有哀怨,幻夢與你對立而坐,微黃燭火下,我挽袖硯墨,你執筆輸卷,這孤寥月影時,品一盞苦茶,各舒泛思。我踏輪迴尋來,只想替你輕輕舒平愁眉,圓你一世之盼。我用手撫你之面,只為慰你一世哀傷;我臂親搭你肩,只為驅你一世沉寂;我細吻你雙眸,只為掩你一世獨殤;我靜站你身旁,只為遮你一世流離……

誰知梅花也有淚,就算寒冰圍裹,仍藏匿一顆純潔瑩透淚花,澆滴花蕊。失去自由,成為任人擺佈的棋子,加疊顛沛流離,與親人,友人,愛人切斷來往。這樣的半世,你是怎樣渡過白黑之交,或許,正是處於奈何間隙,一首首流傳千古的絕跡,才風雨不摧,才讓我與你有了別樣的邂逅,讓我流連忘返於你的詩詞,你的意境,你的情感,深拔不出。

詩詞結尾處,你總把所有美好統統許諾給此生不能相守之人,那有誰又會撿起那個坐在角落,落寞無助的你。前世緣,今世劫,如果世間真有輪迴,前世注定你今世與佛結緣,讓你成為西域最大王;囚禁布達拉宮,綻露出你才氣不凡;流浪在拉薩街頭地邂逅,活灑你是最美情郎。緣字劫,緣起始,劫收尾。如果可以,我甘願舍此生,來護你一路安好。

斑駁紅塵,婆娑歲月,前世緣,此生劫,依舊不換版本的一次次放映。年年歲歲花相似,卻又歲歲年年人不同。時代變了,環境變了,而初識的你我,卻帶著不同心境,觀賞著此出落幕。
