The “margin of error” of a New York City teacher was plus or minus 28 points.  A teacher who has ranked in the 43rd percentile might actually be anywhere between the 15th percentile and the 71st percentile.  The values also fluctuate between years.  A teacher who gets a particular ranking in one year is likely to get a different ranking the next year.

Example 2: Plagiarize the original text by paraphrasing its structure too closely, without copying it word-for-word.

He found that teachers’ ranking for New York City teachers was plus or minus 28 points.  For example, a teacher that was placed in the 43rd percentile could actually be placed as low as the 15th percentile and as high as the 71st percentile.  These values are not consistent from year to year, so a teacher who gets a certain ranking in one year will probably get a different ranking the next year.

Example 3: Plagiarize the original text by paraphrasing its structure too closely, and include a citation. Even though you cited it, paraphrasing too closely is still plagiarism.

He found that teachers’ ranking for New York City teachers was plus or minus 28 points.  So a teacher that was ranked in the 43rd percentile could be ranked 28 points higher or lower in actuality.  Also the values change from year to year, and it is likely that the teacher will get a different ranking every year.  (Ravitch, 270-271).

He found that there was a 28 point margin of error for New York City’s teachers. So any teachers ranking could be 28 points higher or lower than they were actually ranking.  The rankings change annually and it is unlikely that a teacher’s ranking will remain constant.  (Ravitch, 270-271).

No calculation is just right, but the approximations of value-added and other “growth models,” which attempt to separate the “true effect” of an individual teacher through his or her students’ test scores are frighteningly error-prone in any given year.

Ravitch explains that to measure a teachers professional growth from year to year is no perfect science. I believe the problem is defining a measurable variable to establish if professional growth has taken place.  She further criticizes the growth measurement system that utilizes student test scores to determine a teachers growth. She cites a New York Times economist who explains that there are large margins of errors in this type of assessment of teachers professional growth (Ravitch 270-271).

The method that determines a teachers rank is unreliable because of several factors that include actual change in teacher performance and the startling 28 point margin of error. Thus making  it difficult to trust the results (Ravtich, 270)

The method in which teachers’ influence on a particular student’s test score is judged is an inconsistent one. According to Sean Corcoran, an economist at NYU, “the average “margin of error” of a New York City teacher was plus or minus 28 points” (Ravitch, 270). Thus it is difficult to accurately determine actual teacher influence on student, improved teacher performance, or margin of error. This results in a different teacher ranking each year.

As asserted by Diana Ravitch, it is hard to differentiate between a the rankings of public school teachers because there is such a large margin of error in the calculations (Ravitch 270). This margin of error makes it difficult to assess a teachers real performance.

Proving the imperfection of the teacher evaluation system, one economist found that the margin of error in the evaluation system for New York was plus or minus 28 points. This meant that, even if a teacher was ranked in the 43rd percentile, he or she could actually be between the ranks of the 15th and 71st percentile (Ravitch 270).

Example 5: Properly paraphrase from the original text by restating the author’s ideas in different words and phrases, add a direct quote, and include a citation to the original source.

Because of the large margin of error in the teacher evaluation systems, and the fluctuation of scores, the author says, “it is difficult to trust any performance rating if the odds of getting the same rating next year are no better than a coin toss” (Ravitch 271). Clearly, the current system is not an accurate one.

Example 2: Plagiarize the original text by paraphrasing its structure too closely, without copying it word-for-word.

A teacher can get a different ranking score each year because of instability in rankings, which reflect real performance changes. It is difficult to believe performance ratings because they are a toss up.

Example 3: Plagiarize the original text by paraphrasing its structure too closely, and include a citation. Even though you cited it, paraphrasing too closely is still plagiarism.

Stability in rankings is inconsistent because they reflect “real” performance, so they are difficult to trust because a teacher’s ranking can change year-to-year. (Ravitch 270-271)

Example 4: Properly paraphrase from the original text by restating the author’s ideas in different words and phrases, and include a citation to the original source.

In regards to teacher evaluation, Sean Corcoran has found that there is a large fluctuation in how a teacher will be ranked year-to-year. Due to rankings being based off of performance changes that are considered, as Ravitch says “real,” they are inconsistent and therefore cannot be fully trusted. (Ravitch 270-271)

Example 5: Properly paraphrase from the original text by restating the author’s ideas in different words and phrases, add a direct quote, and include a citation to the original source.

After studying how teachers are evaluated in both New York City and Houston, Sean Corcoran discovered that “the ‘margin of error’ of a New York City teacher was plus or minus 28 points” (Ravitch 270-271). This shows the significant difficulty New York City faces in ranking teachers since the margin of error is so large.

As Ravitch says, value added rankings will always be unstable. Some changes reflect real changes in performance, but a performance ranking is hard to trust if the chances of getting the same score from one year to the next are the same as the flip of a coin (Ravitch p.271).

A teacher who is ranked at one level is not very likely to be ranked in the same level after the next evaluation (Ravitch 271).

Example 5: Properly paraphrase from the original text by restating the author’s ideas in different words and phrases, add a direct quote, and include a citation to the original source.

No measure is perfect, and value-added assessments have significant flaws as an evaluating tool because there is inherent “…instability in these rankings…” (Ravitch 271).

Example 1: Plagiarize the original text by copying portions of it word-for-word.

It seems that no measure is perfect, but the estimates of value-added and other “growth models,” which attempt to isolate the “true effect” of an individual teacher through his or her students’ test scores, are alarmingly error-prone in any given year.

Example 2: Plagiarize the original text by paraphrasing its structure too closely, without copying it word-for-word.

Evaluating teacher effectiveness, by estimating value-added or other growth models based on students test scores, is not reliable. Teacher evaluation studies in two major US cities have shown large margins of error in percentile ranking (up to 28 points plus or minus). These scores change year to year.

Example 3: Plagiarize the original text by paraphrasing its structure too closely, and include a citation. Even though you cited it, paraphrasing too closely is still plagiarism.

Evaluating teacher effectiveness, by estimating value-added or other growth models based on students test scores, is not reliable. Teacher evaluation studies in two major US cities have shown large margins of error in percentile ranking (up to 28 points plus or minus). These scores change year to year (Ravitch 270-71).

Ravitch says that evaluating teacher effectiveness, by estimating value-added or other growth models based on students test scores, is not reliable. “Sean Corcoran, an economist at New York University, studied the teacher evaluation systems in New York City and Houston. He found that the average “margin of error” of a New York City teacher was plus or minus 28 points.” These scores change year to year (Ravitch 270-71).

Example 1: Plagiarize the original text by copying portions of it word-for-word.

Truly, no measure is perfect.  But the estimates of value-added and other “growth models,” which attempt to isolate the “true effect” of an individual teacher through his or her students’ test scores, are alarmingly error-prone in any given year.

Example 2: Plagiarize the original text by paraphrasing its structure too closely, without copying it word-for-word.

Sean Corcoran, who is an economist at New York University, has studied the teacher evaluation systems in Houston and New York City. His studies found that the average “margin of error” of a teacher in New York City was plus or minus 28 whole points.

Example 3: Plagiarize the original text by paraphrasing its structure too closely, and include a citation. Even though you cited it, paraphrasing too closely is still plagiarism.

Therefore, a teacher who has ranked at the 43rd percentile in comparison to his or her peers may really be anywhere between the 15th and 71st percentile (Ravitch 270-271). 

Example 4: Properly paraphrase from the original text by restating the author’s ideas in different words and phrases, and include a citation to the original source.

Due to fluctuation for value-added scores, teachers will likely receive different scores over several years.  One year he or she may have a good ranking, and the next he or she may have a bad ranking (Ravitch 270-271). 

Example 5: Properly paraphrase from the original text by restating the author’s ideas in different words and phrases, add a direct quote, and include a citation to the original source.

Ravitch points out that the rankings will never be stable.  Some of the value-added assesments may show accurate performance changes, but many will not.  Ravitch says, “it is difficult to trust any performance rating if the odds of getting the same rating next year are no better than a coin toss,” (Ravitch 270-271).
