Summer Learning Loss: Part 1

Summer Learning Loss: The Problem and Some Solutions

By: Harris Cooper (2003)

In the early years of formal schooling in America, school calendars were designed to fit the needs of each particular community (Gold, 2002). Some communities had long summer breaks that released children from school in spring to help with planting and in fall to help with the harvest, while urban schools sometimes operated on 11- or 12-month schedules. By 1900, migration from the farm to the city and an increase in family mobility created a need to standardize the time children spent in school. The present 9-month calendar emerged when 85% of Americans were involved in agriculture and when climate control in school buildings was limited. Today, about 3% of Americans' livelihoods are tied to the agricultural cycle, and air-conditioning makes it possible for schools to provide comfortable learning environments year-round (Association of California School Administrators, 1988). Nevertheless, the 9-month school year remains the standard.

Concerns raised by the long summer vacation


In 1993, the National Education Commission on Time and Learning (NECTL, 1993) urged school districts to develop school calendars that acknowledged differences in student learning and major changes taking place in American society. The report reflected a growing concern about school calendar issues, especially for students at risk for academic failure.

Educators and parents often voice three concerns about the possible negative impact of summer vacation on student learning. One concern is that children learn best when instruction is continuous. The long summer vacation breaks the rhythm of instruction, leads to forgetting, and requires a significant amount of review of material when students return to school in the fall. Also, the long summer break can have a greater negative effect on the learning of children with special educational needs. For example, children who speak a language at home other than English may have their English language skills set back by an extended period without practice, although there currently is little evidence related to this issue. Children with some disabilities may also profit from summer programs. While there is little evidence that a student's IQ is related to the impact of summer break (Cooper & Sweller, 1987), Sargent and Fidler (1987) provided some evidence that children with learning disabilities may need extra summer learning opportunities. Many states mandate extended-year programs for students with learning disabilities because they recognize these children's need for continuous instruction (Katsiyannis, 1991). And finally, tying summer vacation to equity issues, Jamar (1994) noted that "Higher SES students may return to school in the fall with a considerable educational advantage over their less advantaged peers as a result of either additional school-related learning, or lower levels of forgetting, over the summer months" (p. 1).

The Happiness Diet: Part 2

The Happiness Diet:
Part 2
According to an article on fitbie.msn.com, staying away from processed foods can have a positive effect on more than just your physical well-being

By Tyler Graham and Drew Ramsey, M.D.

Watermelon
The red flesh of watermelon is bursting with the powerful antioxidant lycopene, much more so actually than the tomato. Lycopene protects our skin from the intense summer sun and kills cancer cells. Studies show you can boost the levels of this important nutrient by up to 40 percent (and beta-carotene by 150 percent) by letting it sit outside the refrigerator at room temperature for several days.

Chili Peppers
Neuroscientists recently found that the brain is loaded with receptors for capsaicin, which is currently being investigated for its ability to regulate inflammation by influencing the expression of DNA. We also know that our brains respond to the heat of capsaicin by releasing endorphins, natural compounds that are related to morphine and have a calming effect. Capsaicin destroys carcinogens in our food like dimethyl nitrosamine, a preservative in cured meats, and vinyl carbamate, a cancer-causing agent in many pesticides. And capsaicin has been shown to protect the brain during liver failure. (13 Spices That Help You Lose Weight)

When we eat spicy foods, we release the same endorphins as when we exercise. Just like runners report a post-workout high, chile-eaters talk about a soothing, euphoric response to eating extremely spicy food.

Garlic
Garlic is the star of a family of vegetables known as alliums that include onions, garlic, and leeks. Alliums promote healthy arteries and ensure proper blood flow to the brain. These savory vegetables relax your blood vessels, decreasing your blood pressure, which prevents small strokes in the brain, a major cause of depression and dementia later in life.

Alliums are a top source of a key trace mineral for happiness known as chromium. It's needed for a proper response to the hormone insulin, which helps ensure you're not storing too much sugar as fat. But more than that, it influences the uptake of tryptophan, the precursor to the important neurotransmitter serotonin. It also enhances the release of the neurotransmitter norepinephrine. Chromium supplementation is effective in treating some depressed patients who struggle with low energy and carbohydrate craving. The more sugar in your diet, the more chromium your kidneys excrete, making it harder for insulin to function. Alliums lower blood sugar, and while we don't know exactly why, it may have to do with their high chromium content. Not only that, but the new science shows that allicin in garlic breaks up arterial plaques, essentially reversing heart disease. Garlic also thins blood, further protecting us from heart attack and stroke.

However you slice it, by adding garlic, onions, scallions, or any of the alliums to your daily diet, you'll be protecting your brain, lowering your risk of heart disease, and protecting yourself from the most common forms of cancer (especially of the mouth, throat, colon, and breast).

The Happiness Diet: Part 1

The Happiness Diet:
Part 1


According to an article on fitbie.msn.com, staying away from processed foods can have a positive effect on more than just your physical well-being
By Tyler Graham and Drew Ramsey, M.D.

Wild Salmon and Shrimp
You've likely heard that fish is brain food, but you’ve likely not heard how wonderful it is for addressing funky moods. (Related: 6 Supersmart Seafood Choices) When studies compare the mood disorders in different countries, populations that eat the most fish have the lowest rates of depression, bipolar disorder, postpartum depression, and seasonal affective disorder (the winter blues).

These fats also seem to play a role in aggression. Young boys with lower levels of omega-3s have more temper tantrums and difficulty falling asleep.

Omega-3s have also been studies as a treatment for a variety of brain-based disorders. A 2008 study found fish oil to have equal efficacy to Prozac in the treatment of depression. Eating omega-3s has also been shown to alleviate the symptoms of depression in more than 60 percent of pregnant women.

Cherry Tomatoes
The same compound that makes tomatoes red, lycopene, helps maintain mood by preventing the formation of pro-inflammatory compounds (Search: What are pro-inflammatory compounds?), like interleukin-6, that are associated with depression. This magical molecule is also known to protect against a vast number of cancers (including breast, prostate, and pancreatic). In a study of elderly nuns, those with the most lycopene in their blood lived on an average a whopping eleven years longer than their sisters with the lowest levels. Organic tomatoes have three times as much of this molecule as conventionally produced ones.

Tomatoes are high in other mood enhancers like folate and magnesium, both used to treat depression. They contain iron, tryptophan, and vitamin B6: the main ingredients needed by your brain to produce important mood-regulating neurotransmitters like serotonin, dopamine, and norepinephrine. Add to this a high concentration of niacin, vitamin K, chromium, vitamin C, and potassium, and it makes sense that tomatoes protect us against choronic diseases like diabetes and heart disease. One way these nutrients work is by lowering homocysteine in the blood, a risk factor for depression, heart attacks, and strokes.
