Your school district wants to evaluate teachers based on their students’ scores on standardized tests. In this case, you will use Microsoft Access and Microsoft Excel to create the evaluation system.
Background
Your state’s education officials complain that virtually all the teachers in your school district are rated as good or excellent by their school principals. There are surely bad teachers, state officials say, but they are not identified and the problem is not addressed.
Therefore, the public school district has been instructed by state education officials to devise an accountability system to identify good teachers and bad teachers. Good teachers would be paid more. Bad teachers would be retrained so that they improve, or they would be fired. Fired teachers then would be replaced by good teachers. In this way, officials believe that teaching would improve and students would learn more.
In the new system, subjective evaluations by school principals will not be the only measure of teacher success. In addition to principal evaluations, an objective method is needed to measure teacher performance. Your state’s standardized tests are considered a reliable measure of student learning, which means that the test scores could be used to help measure teacher performance objectively. According to some state officials, teachers whose students do well on the tests are doing a good job; poor test scores must be a sign of bad teaching. The concept of matching teacher performance with student performance is highly controversial.
In your state, public school begins with kindergarten. Starting in first grade, elementary students take a standardized test at the end of each school year. The test has a reading section and a math section; the summary score ranges from 0 to 1000. These standardized tests are given for grades 1 through 8; the test becomes more difficult and comprehensive each school year.
Your district superintendent thinks that parental involvement is a key factor in a student’s motivation and learning. The superintendent wants parents to supervise their children’s homework, meet regularly with teachers, and be involved with the school. The superintendent thinks that children of “involved” parents usually do better in school. In your district, K-8 teachers are required to note the extent of parental involvement, and to report this information as a rating to the principal and the superintendent. Teachers are required to document these ratings by recording missed meetings, missed homework assignments, and so on. District officials think the ratings are reliable because they are documented and are rarely debated by parents.
You have been asked to develop an accountability system that incorporates standardized test scores and parental involvement ratings. Your model will be a prototype. The model will use test score data for all second-grade students in the district. To develop a sample group for comparison, you have identified three second-grade classes in a district school. You have two years of data for students in these classes.
An Access database file named TeacherEval.accdb contains your data. Use Windows Explorer to copy the TeacherEval.accdb database, which is in the MN1505 subfolder within the Management folder on the pclabs (ourdatateaching) (R:) drive, to your Y: drive. [If your Y: drive is full you may need to delete some of its contents to be able to do this].
The tables in the file are discussed next. Figure 1 shows the first few records of the Year1Students table.
Figure 1 Year1Students table records
The table shows each student’s ID number and indicates whether parents are involved in the student’s education. Each second-grader in the district is assigned a unique student number. A lack of parental involvement is indicated by the text value “YES” in the LackOflnvolvement? field. If the parents are involved, the entry is “NO.”
The district had 548 second-grade students in Year 1 of your model. A companion table called Year2Students holds data for second-grade students in Year 2 of your model. The two tables contain two different sets of students. By sheer coincidence, Years 1 and 2 had the same number of second-grade students, 548.
Your model will also include two years of student records for three second-grade teachers in a particular district school. The teachers are named Smith, Jones, and Casey. Figure 2 shows the first few records of the Year1ClassAssignments table.
Figure 2 Year1ClassAssignments table records
The three teachers each had 23 students in their second-grade class each year. Each teacher’s class has a unique number. Here, teacher Smith’s Year 1 class was number 1. The table shows how individual students were assigned to each class. Each student is given a unique number, which is the table’s key field.
Figure 2 shows that teacher Smith had students 1, 2, and 10 among the 23 assigned to her. Teacher Casey’s class of 23 included student 5.In your district, most students attend the school in their neighbourhood. Occasionally, parents request that their child attend a school other than their neighbourhood school, but such requests are not always honoured. Within a school, the principal assigns students to a teacher; the teachers are not allowed to request particular students.
A companion table called Year2ClassAssignments shows how students in Year 2 were assigned to the same second-grade classes used for Year 1. No students were “kept back” at the end of Year 1, so no Year 1 students reappear in a teacher’s class in Year 2.
Each second-grade student in the district took standardized tests at the end of first grade, and again at the end of second grade. Scores for Year 1 students are summarized in the table Year1StudentTestScores.
The first few records of the table are shown in Figure 3.
Figure 3 Year1StudentTestScores table records
Student l’s scores on the two year-end tests were 453 and 456. Each year’s test emphasizes maths and reading, and each succeeding test is more comprehensive and more difficult. Thus, Student 1 did not appear to progress greatly in second grade. Student 2’s second-grade score appears to represent a decline in ability. Student 3’s second-grade test score shows improvement over Year I , although the scores are not high in either year.
The YearlStudentTestScores table has 548 records, one for each Year 1 student. A companion table, Year2StudentTestScores, contains records in the same format for second-grade students in Year 2 of the model.
Your model will use two criteria for assessing teacher performance.
1. Criterion 1: The average test score is computed for a second-grade class taught by one of the sample group teachers. The average test score is also computed for all second-grade students in the district. If the sample teacher’s class average is higher than the district average, the teacher is rated “good” for the year; otherwise, the teacher receives a “poor” rating for the year.
2. Criterion 2: Each student has a first-grade test score and a second-grade test score. The average test score improvement is computed for the sample teacher’s class and for all second-grade students in the district. If the teacher’s class has a better average improvement than

Basically, The graphs attached represent the value of gold from (1970-2000) for every ten years. I used multiple graphs trying to pick the best one to represent the data. I decided to pick exponential as the best one out of the five to represent the values. So to test it out, i did a graph using exponential from (2000-2012) for every 5 years to represent the values to prove that it’s the best one. Lastly, i must use this exponential graph to predict future values of gold. i need is detailed analyzation explaining the benefits and limitations of each graph and the reason behind picking exponential to represent future values. I need to be really detailed and to explain some sudden drops. I have to reflect on the wrongs that i did throughout the paper and how errors could effect some calculations and to reflect on the struggles i went through for this. Also, the conclusion is that no one can predict the values of gold cause it depends on the external environment.(( AT LEAST 10 PAGES))

Topic and Approach
A well-planned programme of research for a dissertation should – broadly speaking – go through a series of stages, irrespective of what you are writing about and the sort of research methods you are using. Put at its most simple, you start by selecting a topic area and doing some general reading. The initial idea may derive from practical experience, from a placement year if you took one, or from your reading for a particular unit. It may derive from an item in the news that seems to raise interesting and not immediately answerable questions. For example, is this a new political development? What were the origins of this movement/party/ideology? How would an intensive study of this problem or policy question (or a comparative study of such a problem or policy area in two countries) illuminate either the problem or the political setting? A recent or imminent political development, such as an election, might allow you to do some original research before academics and experts can publish their own analyses. A dissertation often begins with a puzzle or paradox which suggests the ways in which you might break up and structure your research and therefore make the task manageable. Your question should really start with ‘why’ or ‘how’.

Test 2 – Rock Mechanics, Earth Structures and Earthquakes
1) Compare and Contrast (note: give and explain defining equations or discuss significance where pertinent) (24pts)
a. Normal stress vs. shear stress
b. Tensile failure vs. Coulomb failure vs. frictional sliding

c. Viscous vs. Elastic deformation
d. focus vs. epicenter
e. P-wave vs. S-wave

f. Magnitude (i.e., Richter Scale) vs. Intensity (i.e., Mercalli Scale)

Figure 1.Stress-strain graph from a rock deformation experiment. Note that stress here is given in kiloPascal (kPa) rather than MegaPascal.

2) With reference to the stress-strain graph above, answer or complete the following: (5 pts)
a. Label the following on the curve:
The elastic segment of the curve The plastic segment of the curve
The yield point The point of failure

b. Based on this graph, what is the modulus of elasticity (E) for this material?
3) One of the rock formations that figures prominently in the foundation at our proposed dam site is the Kope Formation. Fleming and Johnson (1994) report the results of residual shear tests on weatheredKope Formation that yielded and angle of internal friction (?f) of 16o and a cohesion (C) of 10 kPa (note – that’s kilopascal, not MegaPascal).
a. Imagine that you needed to excavate a vertical road cut 3 m high through weathered Kope Formation. Assuming a density of 2450 kg/m3 for the Kope Formation, what would be the vertical stress at the base of your 3 m high cut? (2 pts)

b. On the graph paper at the end of this test, plot a Mohr diagram showing the Coulomb failure envelope for weathered Kope Formation based on the values of cohesion and internal friction given above. Then add a Mohr circle to the diagram based on the state of stress calculated for the base of the cut as determined in pt (a). Is weathered Kope Formation strong enough to support a vertical face 3 m high? (5 pts)

4) McFadden (2008) reports unconfined compressive strengths (UCS) for unweatheredKope formation from fresh core in the range of
UCS = 400 ± 400 ksf (kilopounds per sq. ft).
In addition, Oldfield reports values for the Modulus of Elasticity in the range
E = 8 ± 4 GPa (GigaPascal)
a. Noting that 1 ksf = 0.49 kg/cm2 and 1 GPa = 1.02 x 104 kg/cm2, plot and label the KopeFm on the diagram at right. (3 pts)

b. Briefly describe the Kope Formation’s strength and stiffness properties. (3 pts)

Strength:
Stiffness:
Modulus Ratio:

c. See Figure 7.29 – 7.31 in your text. How does the Kope shale compare with the range of values for the above parameters reported for typical rocks in your text? In particular, how does it compare with the range of shale values for typical sedimentary rocks illustrated Figure 7.30? Are you comfortable with the idea of building a major, heavy structure such as a dam with this material as a foundation? (3 pts)

5) What is Elastic Rebound Theory and how does it related to the concept of the earthquake cycle and earthquake forecasting? (3 pts)
6) How does the type of faulting (thrust vs. strike-slip vs. normal) relate to the magnitude of earthquakes produced? (2 pts)

7) We recently had a great earthquake offshore of Iquique, Chile (pictured above). Briefly describe the plate tectonic setting of this earthquake (i.e., what kind of plate boundary did it occur along? What type of fault ruptured?). Was an earthquake of this magnitude at this locality surprising or would it be more accurate to say that it was not unexpected? (3 pts)
8) What is liquefaction and why does it occur? (2 pts)
9) California is presently following the lead of Japan by installing an earthquake warning system. How does this system work? (2 pts)
10) List and briefly describe 3 strategies or principles that could be applied to improve the survivability of buildings and other infrastructure during earthquakes (6 pts)

11) List and briefly describe 3 strategies or principles other than better structural design that have been or could be applied to avoid or minimize the risks associated with earthquake hazards: (6 pts)

12) Contrast the concept of long-term earthquake forecasting with that of short-term earthquake prediction. Which approach has been most successful? What are the basic principles on which each is based? (4 pts)

Part 2 – Ohio River Reservoir-Induced Seismic Risk Analysis
Background and Given Information
The purpose of this exercise is to evaluate whether there would be any reasonable risk of reservoir-induced seismicity due to our imaginary dam construction project on the Ohio River. Forthe state of stress beneath Ohio we will use the samein situ stress measurement that we used for the in-class exercise on the Youngstown seismicity, as detailed below: derived from hydraulic fracturing at a depth of 808 m in Hocking County (from the World Stress Mapdatabase, Heidbach et al., 2008):
Hocking County, Ohio
(based on hydraulic fracturing at 808 m depth):
azimuth of ??: 064°
plunge of ??: 0°
azimuth of ??: 064°
plunge of ??: 90°
azimuth of ??: 334°
plunge of ??: 0°
Magnitude ??: 24 MPa
Magnitude of ??: 14 MPa
Magnitude of ??: 11.3 MPa
Since we have no way of predicting at what depth a possible earthquake might be triggered, so for convenience we will use a depth of 808 m (i.e., we will simply use the state of stress given above for our Mohr construction).
Recall also that the failure criterion for frictional sliding on a pre-existing fracture is given by “Byerlee’s Law” (Byerlee, 1978):
For ?n< 200 MPa: ?s = 0.85?n
Questions
1) Based on the state of stress given above, what type of faults would you expect to find most commonly in Ohio and why? (Normal, Reverse, thrust, or strike-slip?) (2 pts

2) Begin by studying the map of historical earthquake epicenters in Ohio overlain on the map of known Ohio faults. In the table on the following page, list the names of three faults that you believe could be at risk of reservoir-induced seismicity in the table below. Determine the angle ?f that each fault makes relative to the ?? principal plane for the state of stress given above. Assume all faults are vertical. Finally, for each fault indicate whether you would expect a left-lateral (positive) or right-lateral (negative) sense of slip. (Note that for your convenience in measuring angles I have labeled the ??principal stress direction in northern Hocking County. If you would like a clearer view of either figure I am also attaching pdf’s for both maps). (6 pts)

Fault Name Angle to ?? principal plane (?f) Expected sense-of-slip on fault if active

3) Based on your comparison between the fault map and the epicenter map, do you see any evidence that any of these faults may actually have been active in historical times? Which faults, and when do you think they could have been active? (3 pts)

4) On the last page of this document you will find a graph paper grid. Plot a Mohr circle using the state of stress given on the previous page. Clearly Label the points on the Mohr circle that correspond to each of the potentially active fault planes you identified in question 2.1 above. (Note: You may find it easier to use MS Words drawing tools rather than a compass to complete this drafting, but if you prefer to print it out and complete by hand with a compass that is also acceptable). (12pts)

a. What is the mean normal stress for this state of stress?
b. What is the differential stress?
c. Indicate the normal and shear stresses on each of the three fault planes (Make sure you get your signs right on the shear stresses)

Fault Name Mean Normal Stress (?n) Differential Stress (?d) Maximum shear stress (?max)

5) Calculate the pore fluid pressure assuming hydrostatic stress at a depth of 800 m and on your Mohr diagram plot a new Mohr Circle for the effective normal stress taking fluid pressure into account. (4 pts)

6) Assume a pool depth of 50 m (150 ft) for the reservoir. How much would this increase fluid pressures at depth? Are any of your faults close enough to failure that this seemingly minute increase in fluid pressure could actually be enough to trigger an earthquake? Discuss. (5pts)
