These are the automatically computed results of your exam. Grades for essay questions, and comments from your instructor, are in the "Details" section below.

Founded in 1977 in Oregon and Washington State, NWEA’s scholars were Allan Olson, George Ingebo, and Vic Doherty. (NWEA, 2014) The association was dedicated to build a new kind of testing system to measure and track an individual student’s educational level and growth. Over the decades, NWEA has grown from a collaboration of 14 school districts to a global organization. Today, their products and services support educators and their students in over 7,400 schools, districts, and educational agencies worldwide. (NWEA, 2014) Their model was grounded on an “empirically-derived scale based on Danish mathematician George Rasch’s Item Response Theory model. (NWEA, 2014) The Rasch Unit (RIT) scale was developed to measure student growth over the course of a year, and from year to year. The first computer adaptive educational NWEA assessment was launched in

Mean is the average of a group of scores (Woolfolk, 2014). Mean and average are used interchangeably. To find the mean, a teacher will add all of the scores together and divided by the number of tests. For example, a teacher wants to find the mean of the spelling test, the spelling test scores are as the following, 10, 8, 7, 8, 10, 10, 6, 5, 7, and 5. The first step is to add all of the scores together (76). The second step is to divided by the number of tests (10), the quotient is the mean (7.6). The first math equation is 10+8+7+8+10+10+6+5+7+5=76. The second math equation is 76/10=7.6. The mean of the

1. By hand, compute the mean, median, and mode for the following set of 40 reading scores:

The test is administered in the spring and the results provide students, teachers, and parents with an objective view of the student’s strengths and weaknesses. The listening and speaking scores are combined to obtain an overall scale score, as are the reading and writing scores. The overall performance is determined by the scores in each combined area. A conversion chart is provided in each grade band, to convert the raw score to a scale score. Then depending on where the scale scores land will give you the placement level that the student is at. To move from one level to another both component scores must land in the upper level range. A student, who advances in only one

3. Questions 3a through 3d are based on a distribution of scores with and the standard Draw a small picture to help you see what is required.

1. By hand (without using SPSS), compute the mean, median, and mode for the following set of 40 reading scores:

The standard deviation was 20.86. For the SAT Verbal, the mean was 595.05, the median was 598.5, and the mode was 590. The standard deviation was 16.197. For the Test Anxiety Questionnaire, the mean was 24.25, the median was 23.5, and bimodal of 20 and 37. The standard deviation was 8.098.

Sharnae earned the following scores: Reading (419) proficient, Math (414) proficient, Writing (432) Accelerated, Social Studies (414) proficient and Science (401). Sharnae also participated in the NWEA Map Assessment in the spring and fall of 2014. The Map Assessment is an online diagnostic assessment that tests a student's growth from one year. In the spring of 2014, Sharnae scored an RIT score of 233 in Math, placing her in the 43rd percentile. Sharnae was then assessed in Math in the fall of 2014 where her score dropped 10pts to a RIT score of 223, placing her in the 26th percentile. Students at grade level nationally scored an average RIT of 236. No current scores on the MAP test are

7. a) How are the scores reported? b) What kind of scores does the instrument yield?

All questions are worth five (5) points. If there are any graphs on the test, then leave

I combined all of the test results by teacher, classroom in order to have a deeper understanding of the results in teacher and classroom level. I took the average of The Percentage of Students who met or Exceeded their Projected RIT for each teacher. I sorted teachers by their performance and presented it to the admin team (see Appendix B for more information on the teacher performance).

After I corrected all assessments three of them got excellent, while the other was good that means their cognitive ability were between very good and satisfactory, so

A standard score between 86-114 is considered to be within the average range with the average score being 100. A percentile rank between 16-84 is within the normal range with the average being 50. Percentile ranks indicate a persons standing relative to others the same age. E.g. a percentile rank of 20% performs as high as 20% of people the same age. It also indicates that 80% of people the same age earned higher scores (Wiig, Secord, & Semel, 2006).
