Laboratory exercises and reports

For each laboratory exercise listed in the schedule, perform the following tasks.

Assignments

Assignment #1

Assignment #2

Video lectures

Most lectures will be available online on my YouTube channel. I recommend subscribing and familiarizing yourself with the playlist for this course.

Resources

Class resources will be posted here throughout the semester.

Slack

Everyone is required to join the messaging service called “Slack.” We’ll use it to communicate with each other during the semester. The Slack team you need to join is called drrico. That’s a signup link. Be sure to join the channel #577-general-2020.

Graduate student responsibilities

Graduate students have three additional responsibilities: (1) perform a literature search to understand an aspect of each laboratory exercise in greater depth; (2) as part of the introduction to each laboratory report (should be about a page in the standard format), summarize your research, citing least three academic sources; and (3) at the end of the semester, present a detailed description of an application of embedded computing, focusing on the embedded computing aspect of the application.

For resources pertaining to (1), see my Academic Literature Searching Tutorial.

Laboratory policies

A laboratory report will be due on Monday after the week it is due on the schedule. These reports will be submitted via Moodle and must be in accordance with the requirements provided here.

Laboratory procedures should be performed individually, although collaboration is encouraged. That is, discussions of how to accomplish aspects of the lab are great, but everyone should write their own code.

Laboratory reports should also be prepared individually.

Homework, quiz, & exam policies

Homework & homework quiz policies

When assigned, homework assignments should be completed by the Monday after the week it is due on the schedule. There will be a quiz over the assignment on Moodle.

Working in groups on homework is strongly encouraged, but work turned-in must be one’s own.

Exam policies

A midterm and a final exam may be given, but are not planned. If you require any specific accommodations, please contact me.

If applicable, calculators will be allowed. Only ones own notes and the notes provided by the instructor will be allowed. No communication-devices will be allowed.

No exam may be taken early. Makeup exams require a doctor’s note excusing the absence during the exam.

Grading policies

Total grades in the course may be curved, but individual assignments will not be. They will be available on Moodle throughout the semester.

Assuming no exams are given, the grading breakdown is simple.

Reports, code, assignments
100%

For graduate students, 10% of their grade will depend on their final presentation.

Academic integrity policy

Cheating or plagiarism of any kind is not tolerated and will result in a failing grade (“F”) in the course. I take this very seriously. Engineering is an academic and professional discipline that requires integrity. I expect students to consider their integrity of conduct to be their highest consideration with regard to the course material.

Cheating is academic dishonesty as well as unprofessional for prospective teachers. Do not copy other students' assignments, have someone else write your papers or plagiarize published or unpublished materials, or submit work previously graded by other instructors. See Saint Martin's University Student Handbook. Students will be graded not only on their academic success, but on professional conduct as well. Students who fail to show professionalism in their academic or personal conduct (e.g. constant tardiness, excessive absences, and/or other unprofessional behavior) may earn a lower letter grade than the total of semester accumulated points, or may even earn a failing grade.

What is academic integrity? Saint Martin’s University is a community of faculty, students and staff engaged in the exchange of ideas in the ongoing pursuit of academic excellence. Essential to our mission is a focused commitment to scholarly values and intellectual integrity, and a respect for the ideas, beliefs and work of others. This commitment extends to all aspects of academic performance. All members are expected to abide by ethical standards both in their conduct and their exercise of responsibility to themselves and toward other members of the community. As an expression of our shared belief in the Benedictine tradition, we support the intellectual, social, emotional, physical and spiritual nurturing of students.

What is academic dishonesty? Saint Martin’s University defines academic dishonesty as violating the academic integrity of an assignment, test and/or evaluation of any coursework. This dishonest practice occurs when you seek to gain for yourself or another an academic advantage by deception or other dishonest means. You have a responsibility to understand the requirements that apply to particular assessments and to be aware of acceptable academic practice regarding the use of material prepared by others. Therefore, it is your responsibility to be familiar with the policies surrounding academic dishonesty as these may differ from other institutions.

Access and accommodations

Your experience in this class is important to me. If you have already established accommodations with Disability Support Services (DSS), please communicate your approved accommodations to me at your earliest convenience so we can discuss your needs in this course.

If you have not yet established services through DSS, but have a temporary health condition or permanent disability that requires accommodations (conditions include but are not limited to mental health, attention-related, learning, vision, hearing, physical or health impacts), you are welcome to contact DSS at 360-438-4580 or dss.testing@stmartin.edu or smu.dss@stmartin.edu. DSS offers resources and coordinates reasonable accommodations for students with disabilities and/or temporary health conditions. Reasonable accommodations are established through an interactive process between you, your instructor(s) and DSS. It is the policy and practice of the Saint Martin’s University to create inclusive and accessible learning environments consistent with federal and state law.

Sexual misconduct/sexual harassment reporting

Saint Martin’s University is committed to providing an environment free from sex discrimination, including sexual harassment and sexual violence. There are Title IX/sexual harassment posters around campus that include the contact information for confidential reporting and formal reporting. Confidential reporting is where you can talk about incidents of sexual harassment and gender-based crimes including sexual assault, stalking, and domestic/relationship violence. This confidential resource can help you without having to report your situation to the formal reporting process through the Dean of Students – Ms. Melanie Richardson, Associate VP of Human Resources – Ms. Cynthia Johnson, Public Safety – Ms. Sharon Schnebly, or the Office of the Provost – Dr. Kathleen Boyle, unless you request that they make a report. Please be aware that, in compliance with Title IX and under the Saint Martin’s University policies, educators must report incidents of sexual harassment and gender-based crimes including sexual assault, stalking, and domestic/relationship violence. If you disclose any of these situations in class, on papers, or to me personally, I am required to report it.

University sanctioned activities

If a student is absent from class due to university sanctioned activities, such as sports, it is the student's responsibility to request that the absence be excused, otherwise, the absence will be recorded as unexcused. Absent students are responsible for catching up with the class, and if any assignments are due on the day of the absence, it is the student's responsibility to turn in the assignments on time (prior to class).

Religious Accommodation

Saint Martin’s University, in honor of the sacredness of the individual, and being deeply rooted in the Catholic Benedictine tradition of higher education, values the many religious and spiritual practices of our campus community. Saint Martin’s University supports our students in their ongoing journey of becoming. In compliance with Washington State Law RCW 28B.137.010, Saint Martin’s University reasonably accommodates students for reasons of religious observances.

Center for Learning, Writing, and Advising

The Center for Student Success offers free academic services for all Saint Martin’s students. The Center provides subject-area peer tutoring in science, technology, nursing, engineering, math, business, accounting, economics, world languages and other subjects. At the Writing Center, students meet with writing tutors to discuss their academic, personal, and professional writing. The Advising Center works with students on academic advising, connecting with campus support resources, transition and self-exploration guidance, personalized academic improvement plans, learning workshops, and support for changing majors. Disability Support Services is also located in the Center for any student with a disability who needs accommodations. For more information on the Center for Student Success, or to sign up for a tutoring, advising, or DSS meeting, see the website: stmartin.libcal.com/appointments.
