Textbook: Engineering Mechanics Statics, Twelfth Edition by R.C. Hibbeler, Publisher: Pearson, ISBN-10 : 0136091903 | ISBN-13 : 9780136091905

Primary instructional method: Team-Based-Learning (TBL)

Online tutoring and homework: Students need to access www.masteringengineering.com for online tutoring and homework assignment. The course code for this class is EGN3311CHEN2010Fall. All homework will be assigned and completed through the course website within the assigned time window. Late homework will not be accepted for credit, except under extraordinary circumstances. Additional tutoring materials and test grades are available on the course website.

Readiness Assurance Tests (RAT): There will be five 32-point multiple-choice RATs.  Each test will cover material presented in the assigned readings. RATs will first be taken individually (without the help of others) and then again in teams. You will take the individual test (RATi) during the first 30 minutes of class. At the end of the 35 minutes, students will assemble in their teams and take the same test again using scratch-off forms.  The team test (RATt) will last for 30 minutes or less. Students may receive bonus points if their team scores higher than other teams. For example, if a team scores higher on a test than all other teams, each individual from that team will receive 8 points added to their team score. So, if a team scores 32 and all other teams score less than 32, then that team receives a 40 for the RATt score. 2nd place teams receive 4 points. If teams tie, they get equal points.

Appeals for RAT results: If your team feels strongly about the correctness of an item that they missed, the team may submit a written appeal to the instructor. This appeal process must occur immediately following a RAT. Only teams, not individuals, may write appeals. Only teams that write successful appeals get points for that appeal, even if another team missed the same question(s). Appeals are not simply an opportunity to dig for more points. Rather, they are an opportunity for teams to make scholarly arguments for their collective positions. All arguments must be supported by evidence from the textbook or lecture notes. If the appeal is based on an ambiguously phrased question, the team must suggest wording that is less ambiguous. The decision to grant or refuse an appeal will be made by the instructor after class via e-mail. The following is an example of a successful appeal:

            Argument: “We feel that A, rather than B, should be the correct answer to question 1.”

Evidence:  “According to Figure 2, the weight of the object is 10 x 21/2 N, i.e. 14.14 N, therefore the force of 14.10 is not enough to lift the box.”

Group activity:  Members of each team will work together to finish an assigned task. Representatives of all teams will present their results in the class. Students will rank the teams by their results and presentations. All members in the teams that are ranked in the top half of the class will receive 1 bonus points to their final class score. 

Exams: There will be two midterm examinations and one final examination during the semester. There will be NO make-up exams (except for extraordinary circumstances such as emergency or accident with official proof).

Grading:         Homework 5% (bonus)

Readiness Assurance Test I – IV* 40%

Exam I & II 30%

Final exam 30%

*Individual performance 16%, team performance 16%, team contribution§ (evaluated by peers) 8%

§Team contribution: 

Each individual will evaluate the contributions of all other team members at the end of the semester by assigning an average of 8 points to the other members. For example, members of a 6-member team: 1) must assign a total of 40 points (5x8) to the other 5 members in their team (for a 5-member team it would be 32 points, for a 7-member team it would be 48 points) and must differentiate some in their ratings; 2) must give at least one score of 9 or higher with a maximum of 12, and at least one score of 7 or lower.

Team contribution scores will produce differences in grades only within teams. This means that team members cannot help everyone in their team get an A by giving everyone high peer evaluation scores. The only way for everyone in a team to earn an A is to do an outstanding job on the individual and team tests and activities.

Letter Grade         Score range                 Letter Grade   Score range

D+       ≥61 % & <64%                       D         ≥58 % & <61%

       ≥55 % & <58%                       F          <55 %

 

Professionalism Practice

 

In this class, you will become a learning professional.  What's a learning professional?  It's an engineer, lawyer, writer, physician, athlete, and a teacher, too.  Those are all professions in which learning effectively and efficiently and helping others to do this are at the very CORE of the profession.  If a profession doesn't have continued learning at its core, the profession is about to be replaced by software, if it hasn't already.

 

So in this class, professionalism is very important.  In the professional world, your life is influenced by three things:  your own effort, the effort of the people you depend upon, and the way you work together, which is why this course chooses the Team-Based Learning system that  values all three of those things.

 

Twice during the course you will provide professionalism feedback to each member of your team. The feedback should reflect your judgment of such things as:

 

            Preparation – were they prepared when they came to class?

            Contribution – did they contribute productively to the team discussion and work?

            Respect for others’ ideas – did they encourage others to contribute their ideas?

            Flexibility – were they flexible when disagreements occurred?

 

It is important to provide positive feedback to people who truly worked hard for the good of the team and to also make suggestions to those you perceived not to be working as effectively on team tasks. Suggestions to the instructor for improving the course effectiveness are also welcome.

 

Tips to Succeed in EGN3311

1) Come to class prepared: Pre-reading course material is extremely important in the TBL course. Lectures are designed to address issues observed during the RATs, not comprehensively go through the textbook. If you do not read the required text, you will get lost during the class.

2) Actively engage in team discussions: Team RATs and group activities are critical parts of the learning process in the course. Be prepared to share three things with your teammates:  (a) what answer you chose as an individual, (b) why you chose that answer, and (c) how confident you are about it. Sit close together in a circle - this enables easy communication and eye contact, which is very important to team performance.

3) Deliberate as long as time permits - unless a team is full of all-stars, teams who deliberate longer (especially at the beginning of the term) will do better in team activities.
