Common core

"The Common Core is a set of high-quality academic standards in mathematics and English language arts/literacy (ELA). These learning goals outline what a student should know and be able to do at the end of each grade." Included in the list of standards is that they be evidence-based, clear, understandable, consistent, aligned with college and career expectations, include the application of knowledge through higher-order thinking skills, and are informed by other top-performing countries (The Common Core State Standards Initiative 2014).

The primary controversy over the Common Core State Standards, or simply the Common Core, from the standpoint of teachers, parents and students, and even administrators, is not so much the standards themselves, but the assessment process and the high stakes involved. Both the national teacher's unions in the United States initially agreed to them, at least in principle. But both have since become strong voices of criticism. Given a public education system that is primarily funded by local property taxes, rather than by state and federal funds distributed to all schools equally, we see a wide disparity of funding per student throughout the country, with the result that students in schools funded by well-to-do communities are clearly better off than those who are not, sometimes only a few miles away.

What gets measured?

Much has been said about the quality, usefulness, and even accuracy of many of the standardized tests. Math questions have been found to be misleading and poorly phrased; for instance, “Tyler made 36 total snowfalls with is a multiple of how triangular snowflakes he made. How many triangular snowflakes could he have made?”

Some of the essays had questions that made little sense to the students. One notable test question in 2014 that dominated the Internet for a time was about "The Hare and the Pineapple." This was a parody on the well-known Aesop fable of the race between the hare and the tortoise that appeared on a standardized test for New York's eighth-grade exam, with the tortoise changed into a talking pineapple. With the pineapple clearly unable to participate in a race and the hare winning, "the animals ate the pineapple." "Moral: Pineapples don’t have sleeves."

At the end of the story, questions for the student included, "Which animal spoke the wisest words?" and "Why did the animals eat the talking fruit?"

Charter schools

Charter schools are self-governing public schools that have signed agreements with state governments to improve students when poor performance is revealed on tests required by the No Child Left Behind Act. While such schools receive public money, they are not subject to the same rules that apply to regular public schools. In return, they make agreements to achieve specific results. Charter schools, as part of the public education system, are free to attend, and are accessible via lottery when there are more students seeking enrollment than there are spots available at the school. Some charter schools specialize in certain fields, such as the arts or science, while others are more generalized.

Questions & Answers

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone

Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.
Dlovan
Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?

What is specific heat capacity
Destiny Reply
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
