Social Science Dissertations
Student in the social sciences field of academics must submit dissertation papers for candidature in to the PhD degree. This is one of the many social sciences papers that should be submitted by students to evaluate their level of understanding of a specific area or topic and how well they can put it down in their own words resulting to logical flow of concepts. Social sciences papers can take the form of social science essay, social science dissertation, social science research papers, social sciences thesis amongst others. Writing dissertations social sciences papers is different from completing projects on other disciplines. Dissertations in Social sciences papers however, follow the basic traditions of dissertation writing whereby one first writes the dissertation social sciences papers proposal. The main difference between dissertations social sciences papers and the others is the content. Dissertations in social sciences papers are about coherent results obtained after conducting a thorough research and one should avoid using moral and principled considerations in the projects. Many social sciences papers on dissertations find it difficult to expound on the implication of their research. One should therefore learn how to bond their effort with real-human requirements. It is very vital to study and analyze a great deal of previous works that are related to the topic of the dissertation social sciences papers. This way one is guaranteed the capability to give details of the insinuation of their research evidently. Good dissertation social sciences papers have two main distinctive features uniqueness and precision. These are attainable by examination and double-checking data, numerals and statistics that one uses to ensure they are correct and exact. If this two lack, then the committee responsible for rejection or acceptance of the dissertation will actually penalize such errors. In addition, the dissertation social sciences papers must have original topics that are not similar to any other work done previously. The proposed structure for dissertations in social sciences papers contains an introduction, literature review, methodology, findings and discussions as well as the conclusion. Dissertations in social sciences papers must contain understandable and definite topics. The topic can involve a difficulty, or a query or hypothesis that sets the schedule and spots accurately to what requires exploring or discovering. One must have interest and passion for the topic in order to relate it to one’s studies in terms of themes or subjects. The literature review in dissertation social sciences papers must contain information from up-to-date literature of significance to the choice of topic as well as influential resources from the past. It may include sources like books, articles, journals or internet among others. The material from these sources must be well chosen to provide the relationship that there is quality in them that is comparative to current topic. The literature review in dissertation social sciences papers must provide confirmation of how the thoughts and the results have developed till now. The review must be critical by briefly assessing and showing how the dissertation fits in the missing point in other studies. Theoretical underpinnings contribute a lot to the judgment of the dissertation by how well one expresses their understanding of the theory. The approaches used to obtain the results must be clear and the findings accurate with convincing evidence. Finally, the conclusions must show the implications of the findings to the study.

The Earth Science Regents is typically administered at the completion of a New York State Regents level high school course in Earth Science. The examination is based on the Earth Science Core Curriculum which is based on Standards 1, 2, 4, 6, and 7 of the New York State Learning Standards for Mathematics, Science, and Technology.
When do I take the Earth Science Regents?
Your school and science program will determine when exactly you should take the Earth Science Regents exam. The test is administered January, June and August of each school year.
How is the Earth Science Regents set up?
THE LABORATORY PERFORMANCE TEST
Since laboratory experience are an essential part of a science course, a portion of the Physical Setting/Earth Science Regents Examination is devoted to assessing laboratory skills. Tasks have been identified from laboratory experiments that you will have performed during the school year. These tasks, which represent skills that are expected to have mastered, change only slightly, if at all, from year to year.
The performance portion of the examination is administered separately from the written portion, normally two weeks earlier. Arrangements for administering the performance exam are made at each school in accordance with guidelines set by the New York State Education Department.
The scoring for each task is based upon accuracy. Values within a certain range are granted the full 2 points allotted to each task. Values within a slightly larger, less precise range earn 1 point. It is possible to accumulate a maximum of 10 points on the performance on the examination.
Additional information regarding the performance test, including an indication of the six tasks to be completed, will be provided by your teacher when this portion of the examination is given. The following is an outline of the six tasks that have been included in past examinations. The time allowed for completing the tasks at each station is 6 minutes.
THE WRITTEN TEST
The written portion of the Earth Science Regents represents 90 points of the total score and has three parts. You should be prepared to answer questions in multiple-choice, constructed response and extended constructed-response formats. Questions will be content and skill based and may require you to graph data, complete a data table, label or draw diagrams, design experiments, make calculations, or write short or extended responses. In addition, you may be required to hypothesize, to interpret, analyze or evaluate data, or to apply scientific knowledge and skills to real world situations.
Part A –Multiple-Choice
A multiple-choice question offers several answers from which you choose the one that best answers the question or completes the statement. Part A of the exam focuses on earth science content and represents 30-40 percent of the examination.
Part B1 –Multiple-Choice
This section of Part B consists of multiple-choice questions as described in Part A. The combined sections of Part B (multiple-choice plus constructed-response) represent 25-35 percent of the examination.
Part B2 –Constructed-Response
In a constructed-response question there is no list of choices from which to choose an answer; rather you are required to provide the answer. Constructed-response questions test skills ranging from constructing graphs or topographical maps to formulating hypotheses, evaluating experimental designs, and drawing conclusions based upon data. The combined sections of Part B represent 25-35 percent of the examination.
Part C –Extended Constructed-Response
These are constructed-response questions that require more time (15-20 minutes per item) and effort on your part to answer. These questions require you to apply your earth science knowledge and skills to real-world problems and applications. Part C represents 15-25 percent of the examination.
Station 1 .. Identification
Using a mineral identification kit and key, the student will determine the characteristics of two mineral samples and identify each sample by name.
Station 2 .. Classification
Using rock identification charts, the student will classify two rock samples as igneous, sedimentary, or metamorphic and state the reason for each classification, in one or more complete sentences.
Station 3 .. Angular Measurement
Using a plastic hemisphere that models the apparrent path of the Sun, an external protractor, a ruler, and masking tape, the studetn will locate the position of the Sun at a given time and measure the distance between that position and a fixed point.
Station 4 .. Mass–Density
Using a single-pan, triple-beam decigram balance, a minerl density chart, and a calculator, the student will find the density, determine the mass, and calculate the volume of a given mineral sample.
Station 5 .. Setting Time
Using a column of fluid, three sizes of plastic particles of the same density, a stopwatch , and a calculator, the student will determine the average settling time for each of the three sizes of particles.
Station 6 .. Graphing
Using data obtained from Station 5, the student will construct a line graph of average settling time versus particle diameter and will determine the settling time for another given particle diameter.
What Topics are covered on the Earth Science Regents Exam?
All the questions on the Earth Science Regents exam will test major understandings, skills, and real-world applications drawn from the following 8 subject areas:
1. Size, Shape, and Composition of Earth
2. Mapping
3. Rocks and Minerals
4. Weathering, Erosion, Deposition, and Landforms
5. Earthquakes and Plate Tectonics
6. Earth History
7. Meteorology and Climate
8. Astronomy
