In​ 1880 Britain could with some justification be called the ‘workshop of the world’: it produced more than 20 per cent of global industrial output and about 40 per cent of the world’s manufactured exports. In the nearly half-century since Samuel published his essay of that name, historians have done much to undermine the narrative of an ‘industrial revolution’ bookended by the invention of the spinning jenny in 1764 and the New Poor Law of 1834.

If a student either “never attended” or “stopped attending,” faculty should assign an “F” grade in Goldmine. For students that “stopped attending,” faculty should also provide the date of the last known active participation by the student in an instructional activity such as a response to discussion boards, study group, assignments, class lecture, lab, tests, etc. This does not include a student simply logging into the class as this is not considered “active participation.”

Faculty who suspect a student of plagiarism or some form of academic dishonesty must report the suspicion to the Dean of Students via The Office of Student Conduct and Conduct Resolution (OSCCR). OSCCR will investigate the allegation and determine the course of action. It is against Regents’ Rules and Regulations for faculty to make a determination independent of OSCCR. According to UTEP’s Handbook of Operating Procedures Section 4.14, “such action is a disciplinary penalty that violates the student’s right to due process and leaves the faculty member vulnerable to a student grievance petition, a civil lawsuit, and possible disciplinary action by the University.” More information is available in the HOOP.

The TEACH Act checklist, summarizes the 22 (!) prerequisites. Nevertheless, we may be optimistic that, together with fair use, this statute will achieve Congress' goal of facilitating online education.

are a small subset of the uses of online resources educators may wish to make. It only covers in class performances and displays, not, for example, supplemental online reading, viewing, or listening materials. For those activities, as well as many others, we'll need to continue to rely on fair use. Remember, however, when relying on fair use, the fair use test is sensitive to harm to markets. This means that in general, where there is an established market for permissions, there will often be a narrower scope for fair use, and our reliance on fair use should be limited.

The TEACH Act authorizes us to digitize works for use in online education, but only to the extent we are authorized to use those works in Section 110(2), and so long as they are not available digitally in a format free from technological protection.

The statute's complexity provides a new context within which to think about fair use: compared to the many conditions and limits contained in Section 110(2), the four factor fair use test seems simple and elegant.

The audiovisual works and dramatic musical works may only be shown as clips -- "reasonable and limited portions".

The TEACH Act of 2002, expanded the scope of online educators' rights to perform and display works and to make copies integral to such performances and displays, making the rights closer to those we have in face-to-face teaching. But there is still a considerable gap between what the statute authorizes for face-to-face teaching and for online education.

Copyright law provides educators with a separate set of rights in addition to fair use, to display (show) and perform (show or play) others' works in the classroom. These rights are in Section 110(1) of the Copyright Act and apply to any work, regardless of the medium.

Because your institution is likely to be liable, along with an accused individual, for the infringements of faculty, students and staff, most institutions advise such individuals not to use works for which required permission cannot be obtained.

There truly may be no one who cares about what you do with a particular work, but the bottom line is that no amount of unsuccessful effort eliminates liability for copyright infringement. Copyright protects materials whether the owner cares about protection or not.

If you are preparing a commercial product, you will need assurances of authority to grant permission because your publisher will expect those assurances from you.

question them about whether they retained copyright or whether they assigned it to their publisher.

If you know who the author and the publisher are, you can contact them directly. If you do not know who the publisher is, The Literary Marketplace (for books) or Ulrich's Web (for journals - requires login) may help you.  Once you know whom to ask, writing a letter, calling or emailing are all appropriate ways to initiate contact.

Where fair use may be questioned, implied rights may be broader, but an express right to use is best - it's clear and reassuring. It's possible today to search Creative Commons licensed works by license type, or limit your search to be sure that your results include only materials intended for use by educators and students.

You can easily give your works an express license by attaching a Creative Commons license to the materials you post online. It's easy and it sends the message that you want your materials to be part of the flow of creativity. No one creates in a vacuum. Just as you build on others' works, others will build on yours.

So, just by posting online, an author implies a limited license to use their work in this manner.

Simply putting the fingers to the save key creates a copyrighted work. Once expression is committed to a tangible medium, copyright protection is automatic. So, postings of all kinds are protected the same as published printed works.

The teacher who saw the incident in-person can speak about it because FERPA is not a confidentiality law. It only protects what’s in a student’s education record.

If a school denies access to student records to a parent of a student under the age of 18, that’s a FERPA violation

One is that, generally, higher education institutions can choose to release a students’ education records to both parents, provided that at least one parent claims the student as a dependent for tax purposes.

“It should be clear that [the data] belongs to the school, not to the vendor, and that the vendor’s responsibility is to process it for the benefit of the school and its students, and not for the vendor’s own benefit,” McDonald says.

Steps Toward Universal Design of Online Courses

“Law enforcement unit records” (i.e., records created by the law enforcement unit, created for a law enforcement purpose, and maintained by the law enforcement unit) are not “education records” subject to the privacy protections of FERPA. As such, the law enforcement unit may refuse to provide a parent or eligible student with an opportunity to inspect and review law enforcement unit records, and it may disclose law enforcement unit records to third parties without the parent or eligible student’s prior written consent

Schools may disclose, without consent, "directory" information such as a student's name, address, telephone number, date and place of birth, honors and awards, and dates of attendance. However, schools must tell parents and eligible students about directory information and allow parents and eligible students a reasonable amount of time to request that the school not disclose directory information about them.

schools must have written permission from the parent or eligible student in order to release any information from a student's education record. However, FERPA allows schools to disclose those records, without consent, to the following parties or under the following conditions (34 CFR § 99.31): School officials with legitimate educational interest; Other schools to which a student is transferring; Specified officials for audit or evaluation purposes; Appropriate parties in connection with financial aid to a student; Organizations conducting certain studies for or on behalf of the school; Accrediting organizations; To comply with a judicial order or lawfully issued subpoena; Appropriate officials in cases of health and safety emergencies; and State and local authorities, within a juvenile justice system, pursuant to specific State law.

The Family Educational Rights and Privacy Act (FERPA) (20 U.S.C. § 1232g; 34 CFR Part 99) is a Federal law that protects the privacy of student education records. The law applies to all schools that receive funds under an applicable program of the U.S. Department of Education.

These rights transfer to the student when he or she reaches the age of 18 or attends a school beyond the high school level.

For students and educators alike, it's important to think about academic integrity as a learned concept.

Whether in history, social studies, science, or literature, most East Asian students are discouraged from producing original work in an academic setting and instead advised to remember and repeat the ideas of the masters in those subject areas as a form of respect.

nursing students, for example, are focused on the concept of caring for others and illustrate collectivist culture, in both academic study and clinical practice. It is often natural for nursing students to project caring for patients to helping at-risk cohorts in the form of academic collusion.

Students that grow up with this perspective may not understand why citations at the end of a research paper are important; furthermore, citations might even make them feel uncomfortable, as they recognize individual authors above the community as a whole.

A collectivist culture is one that prioritizes the goals and desires of the whole over the needs of the individual. Often in East Asian countries like South Korea, Japan, and China, ideas that are beneficial to and shared by the community are not individually attributed, but rather recognized as universal knowledge.

But that practice fails to recognize that students are responsible for their own computer access and stable internet connection.  Although the District-sponsored Learning Manage System will, from time to time, have problems, students need to accept responsibility for their own actions, actions that might be conveniently blamed on an impersonal component of technology.

It is a violation of the academic honesty and intellectual integrity policies of SBVC to log in to someone else's account and pretend to be that person.

Method: Instructors use check-ins and/or office hours to discuss content, previous assignments, and progress on existing assignments.   Process: Instructors ask for identification and/or confirm student identity via official UConn photo in StudentAdmin.

Instructors should check student identity by verifying IDs in a one-on-one online meeting prior to the presentation.

Federal Regulation §602.17: Application of Standards in Reaching Accreditation Decisions requires that all public universities have processes in place through which the institution establishes that a student who registers in any course offered via distance education or correspondence is the same student who academically engages in the course or program; and makes clear in writing that institutions must use processes that protect student privacy and notify students of any projected additional student charges associated with the verification of student identity at the time of registration or enrollment. Please see the Electronic Code Federal Regulations for more information.

The ethical standards outlined above apply throughout the academic community.  These guidelines apply to faculty and research assistants in their possible use of students’ and colleagues’ research and ideas, as well as to students’ use either of source materials and authorities or of other students’ ideas and work.

others result from sloppy scholarship or failure to follow proper format for crediting sources.  For example:

Plagiarism is taking credit for someone else’s ideas, work, or words.

All academic relationships ought to be governed by a sense of honor, fair play, trust, and a readiness to give appropriate credit to the intellectual endeavors of others where such credit is due. Since the academic community expects that the process of intellectual and creative endeavor is beneficial to a student, the student's original work, created in response to each assignment, is normally expected. The following rules and guidelines are intended not to replace an atmosphere of trust and cooperation in the pursuit of knowledge, but rather to assure due process and to provide guidelines for action in those instances where the proper relationships and attitudes have broken down.

If plagiarism is suspected, students might be asked to defend or verify their work as their own in one of the following ways: Present notes, drafts, or works cited Produce an on-demand work sample Present an oral defense of work in question

malpractice outlined by the IB Organization as behavior that results in, or may result in, the candidate or any other candidate gaining an unfair advantage in one or more assessment components. The following definitions are helpful in understanding our complete definition of malpractice: Plagiarism is taking credit for someone else’s words, work or ideas without giving them credit. Collusion is letting someone copy from you or letting someone turn in your work as theirs. Duplication of work is turning in the same assignment for two or more classes. Misconduct during an assessment is copying someone’s answers, letting someone copy your work, looking up answers, bringing answers into the test room, or using tools/material that the teacher has not approved. Confidentiality is not sharing assessment content, question, or answers with students who have not yet taken the assessment.

The author made an observation that it is possible to draw a link between plagiarism and the concept of "loyalty" (based on Sykes and Matza 1957) that can be exploited to explain students’ attitudes and improper academic practices. The author believes that the interviewed students commit plagiarism not because of their unethical or immoral intentions, but rather due to specific hierarchy of values that they follow.

t is the student’s responsibility to provide for supervision of his/her children while they are on campus for class, in a virtual class,

Disruptive behavior in the physical classroom or the virtual classroom is not permitted. Students will receive a warning and may be asked to leave the classroom if necessary.

Cheating, plagiarism Conduct that jeopardizes health and safety Tardiness Profanity Pornography Children or pets in class Private conversations or inappropriate displays of affection Uncooperativeness Continually leaving one’s seat Eating and drinking Reading unrelated materials Use of all unauthorized electronic devices, such as walkmans, phones, beepers, pagers, ipods, and music players. Soliciting of funds and/or signatures

Disruptive behavior includes behavior that interferes with the legitimate instructional, administrative, or service functions of the college.  However, should any behavior threaten the personal safety of any student, faculty member, staff, or administrator, or be displayed with such emotional intensity that it causes fear or concern in others, at that point such behavior is classified as a CRISIS and will necessitate a call to Campus Safety (925) 424-1699.

If online class, faculty can moderate and/or temporarily disable LMS functions to prevent the student from further activity until a resolution is determined.

Talking when the instructor or others are speaking

The following behaviours do not constitute bullying.(a) A single incident of unreasonable behaviour. However, single or one-offincidents of unreasonable conduct can also cause a risk to health and safetyand may breach other University policies and should not be ignored.(b) Reasonable management practices.(c) Low-level conflict as defined in subclause 8(3).(2) Reasonable management practices include (but are not limited to):(a) a direction to carry out reasonable duties and instructions;(b) a direction to comply with University rules, protocols, policies andprocedures;(c) setting reasonable goals, standards and deadlines;

The public’s attitudes diverge in similarways on some of the more severe behaviors in the scenario. Most prominently, 85% of Americansthink that Julie experiences online harassment when she begins to receive vulgar messages abouther looks and sexual behavior. But substantially fewer (although still a majority at 66%) think thatthe social media platform has an obligation to step in and address that behavior.

The public has a higher threshold for behaviors thatconstitute “online harassment” than for behaviors that necessitate a responsefrom social media platforms

Again,majorities agree that the platforms should step in to address behaviors such as threateningmessages.

ave found that online harassment is a common phenomenon in thedigital lives of many Americans, and that a majority of Americans feel harassment online is amajor problem.

Project Teams serve several purposes:

the program provides a combination of traditional instruction and the enhancement of nontraditional instruction and learning that takes place within a Project Team.

The classrooms, student center, and project team locations are places to learn, to socialize and to grow. Each person must be recognized to have certain rights which do not conflict with the Community Expectations nor infringe upon the rights of others in the spirit of the University motto “to served, and not be served.”  These rights include the following: The right to study without distraction. The right to personal privacy. The right to study in a clean environment. The right to be treated with respect and dignity. The right to hold different values. The right to redress grievances. The right to serve the community.

Academic Misconduct/Honor Code violations are related to a student’s class work, the appropriate response is vested in the professor.

All communication between students and other students, or between students and faculty, must be conducted in a manner that is respectful, using language that is professional.

Degrees of Disciplinary Sanctions:

The use of mobile devices (cellphones, beepers, tablets and other smart devices) in the classroom is determined by the faculty member’s mobile device use guidelines for that class. Adhere to the expectations communicated by the faculty member for that course.

any act that constitutes violent behavior and any other behavior that adversely affects the College or its educational programs or mission.  Attempts to commit acts prohibited by the Code may also be addressed through the conduct process. All members of the College community, students, faculty and staff, have the responsibility to report nonacademic misconduct.

If a disruptive student refuses to leave when told, the faculty member will contact SCF Public Safety to remove the student.
