Activity Description: Provide a brief description of the activity

Students in the class are required to work on their projects of gearboxes which are supposed to use in different applications in practice. The project includes four parts: (1) proposal. Students will find out their favorite topic and discuss their project plan with respect to the problems existed in current products, the advantages of their design, the implementation of the plan and future applications. (2) modeling and simulation. The gearbox should be simulated firstly in order to get rid of the possible bugs related to manufacturing. (3) Mid-term report. The students are required to submit a midterm report in order to guarantee that they are working in the correct direction. (4) The project presentation and the final project report.

Learning Goals: What do you aim to achieve with this activity?

Through this design, the students will have the knowledge of the concept of product design and manufacturing, familiarize themselves with the design procedures, learn how to respect the multicultural traditions, learn how to work in a team, learn how to prepare for their professional career, and study how to integrate the fundamental theories into practice.

Timing: At what point in the lesson or semester do you use this activity? How much classroom time do you devote to it? How much out-of-class time is expected?

This activity is semester based. So, the students will be required to submit their proposal at the 3rd week. Then, the need to finish their modeling and simulation task at the 8th week. At the 9th week, the first project report is required. At the 12th week, they should prepare all the parts used in the project and be ready to assemble. At the 15th week, the presentation and gala are hosted.
This project is supposed to work in class, and the students are not necessary to take extra out-of-class time. The students will be given 1 hour per week to work on their projects.

Logistics: What preparation is needed for this activity? What instructions do you give students? Is the activity low-stakes, high-stakes, or something else?

For the project, there are some things to prepare. During the proceeding of the project, fundamental knowledge is given. Following that, the students need to do a survey and find out their favorite project. The project report template is distributed in order to facilitate them to work on the report. In addition, the students are provided tooling machines and 3D printers to manufacturing all the necessary parts.

The project is, in fact, an in-class project. So, it is a low-stakes activity.

Assessment: How do you assess this activity? What assessment measures do you use? Do you use a VALUE rubric? If not, how did you develop your rubric? Is your course part of the college-wide general education assessment initiative?

I used a rubric to evaluate the project. This work is also one part of the college-wide general education assessment initiative regarding teamwork this year.

Reflection: How well did this activity work in your classroom? Would you repeat it? Why or why not? What challenges did you encounter, and how did you address them? What, if anything, would you change? What did students seem to enjoy about the activity?

This is a semester-based activity. As a critical course in my department, this course will be repeated.

Additional Information: Please share any additional comments and further documentation of the activity – e.g. assignment instructions, rubrics, examples of student work, etc. These can be links to pages or posts on the OpenLab.

The project in machine design is very important. The students will have the knowledge of the concept of product design and manufacturing, familiarize themselves with the design procedures, learn how to respect the multicultural traditions, learn how to work in a team, learn how to prepare for their professional career, and study how to integrate the fundamental theories into practice.

Reflecting on students cultural background on the thermal environment, microclimate data will be collected and analyzed to find the common range of comfort zone. The process includes the following. 1) Write a short essay on personal thermal environment in the childhood [temperature, humidity, solar exposure, clothing level], 2) Collect microclimate data as individual and illustrate the characteristics of the environment and the clothing types, 3) Visualize the collected data on psychrometric chart and assess for thermal comfort and satisfaction , 4) Analyze the result for the differences and similarities with other students and with ASHRAE standard, while reflecting on the essay on personal history on thermal environment.

Learning Goals: What do you aim to achieve with this activity?

The goal of the assignment is to provide an understanding of how a cultural background would influence thermal comfort of an individual while enhancing student’s capacity 1) to analyze and
2) visualize numerical data, 3) to communicate effectively, and 4) to work collaboratively.

Timing: At what point in the lesson or semester do you use this activity? How much classroom time do you devote to it? How much out-of-class time is expected?

The activity can be deployed in the first class or any class early in a semester. After a relevant background is introduced as a lecture format, students as individual spend 1 hour to measure microclimate data and 1 hour to analyze during the class. Each student writes a short essay outside the class for 1 hour and adds microclimate measurement for 1 hour. Visualizing the data on a psychrometric chart would take 1 hour. Totaling 5 hours in and out of the class, students present their outcome as individuals in the following week.

Logistics: What preparation is needed for this activity? What instructions do you give students? Is the activity low-stakes, high-stakes, or something else?

Handheld device to measure microclimate are required. ASHRAE standards for thermal comfort shall be prepared. Critical writing is associated with the analysis of numerical data.

Network Brand (The Manifesto pt1)

George Larkins

Communication Design

COMD 3521 Motion Design 1

Activity Description: Provide a brief description of the activity

Students are to create a manifesto designed to launch their network. Here is where it all starts. Where they have to look within themselves and develop the courage to share their beliefs with the world. I have them start off with what they believe and what they know to be true. Ex. I believe that racism is real. I know that discrimination exists in this society.

Learning Goals: What do you aim to achieve with this activity?

My aim here is to create an environment of ethical and honest reasoning designed to withstand the pressure that business demands. In addition to aid in rebuilding their self-belief system.

Timing: At what point in the lesson or semester do you use this activity? How much classroom time do you devote to it? How much out-of-class time is expected?

This project is part of their final. We devote two entire class sessions dealing with this. Out of class time is constantly encouraged. What I tell them is the more time you spend on a subject, the better it will become. If time permits, I share with them a video of the “Long Game, part 2.” https://vimeo.com/87448006

Logistics: What preparation is needed for this activity? What instructions do you give students? Is the activity low-stakes, high-stakes, or something else?

The instructions for this exercise is to start with a list of beliefs. What would do be doing right now in your perfect world? Are you preparing yourself go along with the future or are you preparing yourself to help shape the future? Do you believe that you can have an impact on this planet? Who are your design heroes, and why? And in order to do this, they have to develop the skills the right questions, not only questions from other people but of themselves as well. And have the courage to ask and answer honestly.

Assessment: How do you assess this activity? What assessment measures do you use? Do you use a VALUE rubric? If not, how did you develop your rubric? Is your course part of the college-wide general education assessment initiative?

I will use the creative thinking value rubric. I believe it fits this activity well.

Reflection: How well did this activity work in your classroom? Would you repeat it? Why or why not? What challenges did you encounter, and how did you address them? What, if anything, would you change? What did students seem to enjoy about the activity?

The activity went well, and yes, I will be repeating it. Why, because I believe it is an important skill set to have. That is having the courage to ask questions, be asked questions and give honest answers. My challenge has been getting students to manage the fear of being put in the spotlight. I address that issue by having students give their presentation in front of the class. One possibility would be to review some contemporary design and some history so that they would be more aware of the people that came before them. And also aid them in finding someone who could they can follow and be inspired by.

Additional Information: Please share any additional comments and further documentation of the activity – e.g. assignment instructions, rubrics, examples of student work, etc. These can be links to pages or posts on the OpenLab.

The next step here for will be to get more familiar using openLab.

Activity Description: Provide a brief description of the activity

In this workshop, you will work in teams and groups of teams to create a model suspension bridge. Your model suspension bridge will be tested until structural failure. In reflections, you will individually analyze the strengths and weaknesses of your modeled suspension bridge.

Learning Goals: What do you aim to achieve with this activity?

• Developing your understanding of suspension structures
• Increasing your analysis and problem-solving abilities
• Sharpening your observation and reflection skills
• Deepening your collaborative team techniques

Timing: At what point in the lesson or semester do you use this activity? How much classroom time do you devote to it? How much out-of-class time is expected?

This workshop should occur towards the beginning of the semester as part of the introduction to observation skills and techniques.

Logistics: What preparation is needed for this activity? What instructions do you give students? Is the activity low-stakes, high-stakes, or something else?

Low-stakes

Each team will utilize the following kit of materials:
• Wood blocks (4” x ¾” × ¾”), 18 min
• String, 8’ lengths
• Straws, 14
• Sheets of paper, 3 @ 4” x 17”
• Scissors
• Masking tape, 3’ length
• Tape measure (only one for the workshop required)

Team goals
Construct a model of a suspension bridge utilizing only the materials provided. The bridge must be strong enough to support at least one cell phone at its center. [Recommendation; offer extra points for every additional cell phone the bridge can support]

Team makeup
Each bridge group will consist of two 3 to 4 member teams. Each team is responsible for one half of the bridge spanning from one of the supporting tables to the center of the bridge.

Bridging the gap
Each bridge group will need to span between two tables set 36” apart.

Bridge assembly
The bridge constructed should include the following parts:
• Anchorage (blocks)
• Deck (paper)
• Main cable (string)
• Suspender cables (straws)
• Tower (blocks)

Timing
Your bridge group will have 20 minutes to develop your solution before testing will commence.

Testing
The structural integrity and quality of your bridge will be tested by checking to see how many cell phones the bridge will be able to support. The class will observe as each bridge is tested. Be ready to document where and what are the causes of structural failure. At 20 second intervals, additional cell phones will be added to the Main span of the bridge until the bridge collapses. [It’s recommended that students be ready to catch their cell phones and have their hands under the bridge at least 3 inches away from the bridge deck]

Assessment: How do you assess this activity? What assessment measures do you use? Do you use a VALUE rubric? If not, how did you develop your rubric? Is your course part of the college-wide general education assessment initiative?

Reflections /Documentation
Each team member will need to post on the Open Lab their reflections on this workshop. Be sure to include the following issues in your reflections:
• What strategy did your team used to solve the problem?
• Did you use the iteration process effectively?
• What were the hardest team organization challenges?
• What are the hardest technical challenges?
• What part of the bridge did you think would collapse first?
• What part did collapse first and why?
• Include at least two photographs, sketches or diagrams in your reflection.

Assessment
This assignment will be evaluated by reviewing your reflections on the Open Lab. The focus of this evaluation will be the lessons learned in this workshop. Additional points will be given for each cell phone your groups bridge could support.

Reflection: How well did this activity work in your classroom? Would you repeat it? Why or why not? What challenges did you encounter, and how did you address them? What, if anything, would you change? What did students seem to enjoy about the activity?

Following are some quotes from student reflections on this project. Additional reflections can be seen at this site:

https://openlab.citytech.cuny.edu/aptekar-berger2205sp2017/assignments/216-reflection-on-suspension-bridgeobservation-sketch/

“Today’s class project was very challenging and hands on. It is something I enjoyed doing because my team worked well together to create a steady bridge. Although, it took some time to figure out how to actually build a proper bridge was kind of difficult considering I know nothing about architecture or building. My team mates worked together from putting straws together to taking down blocks to the table. Overall, we learned that the anchorage is the most important part which is something our bridge lacked. Now we know for next time what to spend more money on.”
Alexandra Linik

“…

3. I learnt that the cabling is as important as the others structures as well. Since it is suspension bridge, both the weight of the deck and the live loads will be hung by the suspenders. So the connection between the horizontal cable and vertical cables should be strong enough to hold all the weights. And the angle of the cable from the anchorage should be calculated in order to reduce the extra forces.

4. Lastly, I think we can design our towers of the bridge more pretty, because I learnt that putting weights on the towers do not help in order to stabilize the bridge.”
Alice Myint

“In today’s class the most interesting and challenging part was to make a suspension bridge using small wood blocks, ribbon, tape, paper and our creative mind of course. I got to know some of my classmates whom I have worked with throughout the project. I think architectural stuffs sounds like easy, but it’s really not and the worst experience was when we made the bridge and it’s collapsed twice. But we did not lose hopes and we made a well -organized and furnished bridge with beautiful two anchorages and deck. The “deck” should be strong because the weight on the bridge is related on the base and it’s connected to the deck of both sides of the bridge. We put 4 phones on the bridge and it was still in the same position, but however it collapsed when 5th phone added on the bridge. But in the class we had much fun when working with as a group. We were very excited to see how others work done and that was the coolest part because we can learn something how they made their own. Overall, it was very cool, making a bridge with elementary stuffs and a great experience to work with my classmates.”
Mdzafar Sadak

“The class project that we have was pretty intresting because we get to work together as we form two group. One group was to build one half of the bridge and the other group would do the other half of it. The challageing part was trying to combine the bridge and form a deck that could support the weight. We through that it would help but as it turn out after we finish building it and testing it that it wasn’t the deck that we create can support the weight it was the anchor was the most important part of it that would have support the weight of it. The thing that i learn most was no matter what type of bridge that people make if the anchor is not strong enough then the whole bridge would fall.”
