The Introduction Assignment (1/2 to 1 page) must be written in your own words (even the procedure). References are mandatory, if students use information that was not developed by them (please include the lab manual). The Introduction assignment must be delivered before each class. No partial grade is given if Introduction Assignment is delivered late. In this document, students need to include the information that can answer the following questions:  a. Standard number: what is the standard number that is used for this experiment (2 points) b. Introduction: Why we need to perform the experiment (purpose of experiment)? (2 points) c. Procedure: How do we run the experiment, in terms of steps performed? What equipment needs to be used (2 points) d. Conclusions: What kind of results you expect to obtain and how to get them? (3 points) e. References: all references you used to write the document must be in the document (0.5 points) f. Presentation: The document must be presented in an organized and in a neat way (0.5 points) 2. Attendance will be taken any time after 10 minutes of starting of class. If students are not on time and if the name of students is called but they do not reply, 15% will be deducted on the final grade of report. Attendance can be taken multiple times during the class, to make sure the student is attending the online class. 3. The Cover page should contain title, the name of student, course number and section, date of the class and date of report.  4. Show one sample calculation (formulas and values used), similar to that shown in the manual, for each experiment. If you need to use any values of tables/graphs/etc., an explanation must be included. If you use symbols, they must have a label (e.g. “𝑒” is the void ratio). 5. Results should include the completed data sheets, tabulated results and/or graphs, and computer output sheets (when applicable). Tables and graphs must have captions and must be well labeled (titles, units, points of interest, tangents, etc.).   Figure 1: Deviator stress curves for sample 1 and 2  Correct: units, labels, points of interest, title, etc. Wrong: missing all important information  Correct table Table 1: Results obtained per type of sample ID Void ratio (-) Relative density Dr (%) Confining pressure σ3 (psi) Deviator stress Δσ (psi) Peak stresses ratio σ1/σ3 (-) Vol. strain ΔV/V (%) Axial strain  𝜀 (%)          Wrong table  ID e Dr σ3 Δσ σ1/σ3  ΔV/V 𝜀                 6. In the “Discussion chapter” comment on the accuracy of your results and compare your results with those of others, in identifying your sample of soil and its properties (do not compare your results with other students – you must compare your results with scientific articles, journals, books, websites, class notes, etc.). Comment on deviations from the prescribed procedure (do not write the procedure), limitations of equipment, and explanation of sources of error, and how all of these affect (or not) the results. (1 to 2 pages). Specific questions might be asked during the classes that need to be answered accordingly in this chapter. When commenting and/or discussing, the final results must be explained why and how they were achieved. 7. In “Conclusion chapter”, the students must write a brief summary the laboratory exercise (1 paragraph). The students need to include all final conclusions (values and points of interest that were analyzed in the discussion chapter, type of soil, etc.) (1 paragraph).  8. References if any shall be provided in standard ASCE format (see ASCE citation style guide1). In the “References chapter”, the detailed information of each reference used must be included: if information is used from any website/book/lecture notes/etc., but the credits are not given to the author (in the Report and Introduction assignments), points will be deducted from the report’s final grade. There are two types of copying:  Direct copying – when information is directly copied without changing author’s words. Quoting symbols (“XXX”) and references must be used  Indirect copying – when information is rewritten in students’ own words. References must be used: e.g. - According to Bareither et al. (2008), it is believed… 9. Students are not allowed to copy and paste information that it was not developed by them. Students cannot, as well, share their reports to other students, allowing other students to copy from them.  Students can change ideas between them in order to write their reports and to improve their social skills and knowledge. However, the students are not allowed to share information that was developed by them, namely reports, excel documents, graphs, tables, equations, formulas, etc.   “Academic Integrity is the cornerstone of higher education and is central to the ideals of this course and the university. Cheating is strictly prohibited and devalues the degree that you are working on. As a member of the NJIT community, it is your responsibility to protect your educational investment by knowing and following the academic code of integrity policy that is found at: http://www5.njit.edu/policies/sites/policies/files/academic-integrity-code.pdf.     Please note that it is my professional obligation and responsibility to report any academic misconduct to the Dean of Students Office. Any student found in violation of the code by cheating, plagiarizing or using any online software inappropriately will result in disciplinary action. This may include a failing grade of F, and/or suspension or dismissal from the university. If you have any questions about the code of Academic Integrity, please contact the Dean of Students Office at dos@njit.edu” In Short:  Online submission of reports to obtain a grade.   Individual reports.   Reports must be written in proper English and with the scientific names learned in classes. If not, points can be deducted.  Assignments will be due at the date mentioned by Professor (please see the online submission tab at the online system to know the exact hour and date).   The reports must be uploaded on the online system of NJIT. The TA will note the date and the time of submission. Reports by email are not acceptable, except if the online system is not working properly (keep in mind that the reports sent by email still need to be send on time for students to not lose any points).   Late Assignments will be subjected to a late penalty. If students do not deliver on time the assignment named “Introduction”, no partial credits are given. If students do not deliver on time the assignments named “Report”, a penalty of 25% is applied per each late day to the written document only: 1 day late – 25% penalty, 2 days late – 50% penalty, 3 days late – 75% penalty, 4 days late – 100% penalty (the report will be scored zero).                                                           1 https://www.canterbury.ac.nz/library/support/citations-and-referencing/asce-citation-style/  (In)direct copied reports will be score as zero. First occurrence: the students will get a warning, second and next occurrences: the reports will be scored zero and an email will be sent to the Dean of Students.
