Author: WayneOwl. Here are the correct answers And none of them have anything whatsoever to do with the "distances from the sun" between different points on the globe which are infinitessimal compared with the distance of the entire globe from the sun.
Outside the tropics and the polar regions, the essential characteristic of the annual cycle is a temperature oscillation between a single maximum and a single minimum. This oscillation results from the annual variation in the angle at which the Sun's rays reach the Earth's surface and from the annual variation in the duration of sunlight on the Earth's surface each day.
During the other six months, these conditions are reversed. See the Figure. In polar latitudes, the seasons consist of a short summer and a long winter; this division is based primarily on sunlight, as there is continuous darkness all winter and continuous daylight or twilight all summer.
In low latitudes, where the range of the annual insolation receipt of solar radiation and temperature cycle is very small, seasonal weather variations are based largely on rainy and dry periods. These moisture variations result from the movements of the intertropical convergence zone, a narrow belt of abundant precipitation that encircles the Earth near the equator.
It shifts north and south seasonally with the Sun and causes the areas it crosses to have alternating wet and dry seasons; those regions very near the equator that are crossed twice each year by this belt have two wet and two dry seasons.
In India, a marked seasonal alternation of rainfall and drought, caused by the monsoon, extends northward into latitudes where distinct temperature seasons also exist. The result is a cool, dry season from December through February; a hot, dry season from March through mid-June; and a rainy season from mid-June through November. Courtesy of Encyclopedia Britannica I suppose community college teachers don't have to check the facts because they are so 'certain' that they know.
Then again, I also haven't been to Harvard or anywhere else where people are supposed to be so much "smarter" than J6P. I am staggered that some of the people intervied did not know that. An English major perhaps I could understand but science and physics majors?
I knew that in 7th grade. In fact I corrected my teacher on the explanation. I was really big on stars and planets and rocks and stuff in grade school. Hmmm Given that I corrected my science teacher perhaps I should not be staggered that those people did not know.
Correct, at least for some of us :- The point that I wanted to express in my previous post is: today's students actually have a lot of info stored in their heads, some of which they understand better than other - they simply do not yet know how to express that in a 'knowledgable' way, especially with complex subjects like 'what causes seasons'.
The interviewer asked the respondent to describe a fairly complex process, likely in a 'man on the street' setting, and then perhaps even cherry-picked the answers to support his contention that today's students are ignorant and therefore public education is failing. IMO, the interviewer is revealing an error in logic ralph IMO, the interviewer is revealing an error in logic ralph :- I am sorry the answers given the earth is closer to the sun in the summer is just plain WRONG.
Actually it is wrong on TWO accounts. The earth is on a very slight eliptical path. The earth in the northern hemisphere is actually closer to the sun in winter than summer. It is the axis of the earth the angle to the sun that determines the seasons not some slight difference on an eliptical path.
It occurred to us that there might be a way to measure this kind of teacher knowledge easily without needing to spend long periods of time observing teachers in their classrooms. To help teachers hone this knowledge, Sadler and his colleagues have made the kind of tests used in their study publicly available. More than a dozen tests covering kindergarten through grade 12 are downloadable here, after completing a tutorial on their development and interpretation.
Going forward, Sadler said he hopes to conduct similar studies in the life sciences, particularly around concepts such as evolution and heredity. This is particularly important as states adopt the recently released Next Generation Science Standards.
Knowledge of student misconceptions is a critical tool for science teachers. Funding for this research was provided by the National Science Foundation.
The question is when does that discrimination cross the line from targeting customers to negatively impacting an entire group of people? A professor of science education at Louisiana State Univ. Heather Mars, the middle schooler in A Private Universe, recalls the reaction to the video and her subsequent experiences in education. A session about the making of A Private Universe, with remarks from the creators, education leaders, and Heather, the former middle schooler featured in the film.
