program [4]. The assignment in this paper is categorized in Prince and Felder’sdefinition of Project-Based Learning (PBL). The students work in pairs to formulate a plan basedon prior knowledge from other courses and new learning. The product is the primary outcomethat is judged, more so than the process. PBL should lead to an increase in conceptualunderstanding, metacognitive skills, and positive feelings about learning the material [2]. Sincethe project is done in pairs, students will also have the chance to advance their communicationand teamwork skills. With all types of inductive learning, there is more self-directed learning andopen-endedness than with deductive lectures [1].PBL in ECE is often used in capstone projects, although examples

Participants are selected from their responses to an on-line application form, two rounds oftelephone interviews, and a written commitment that if selected for the camp the student willparticipate for all four weeks. The application includes questions about prior experience withhigh school engineering courses, in-school and after-school STEM experiences, and planning forcollege. The application and interviews ask students to explain why they are interested in thecamp and to describe a situation where they overcame an obstacle to reach a goal.

It also helped students to connect how electronic components of prototype interacted with each other. Students practiced independently creating flow charts in assignments during the term to create a functional Arduino device of their own creation. Flow charts were further used on the final team design project to collaboratively plan the code and functions of their team prototypes.

Faculty development efforts were originallyenvisioned as a way to keep faculty current in their discipline, because it was assumed that if youknew your discipline, you could teach it [2]. However, in the 70s and early 80s, facultydevelopment efforts shifted to focus on instructional development [3]. Much facultydevelopment literature and institutional efforts have focused on initiatives that may be describedas planned or formal, taking the form of workshops and seminars [4].

The project plan to achieve the project objectives includedsome key goals:• Provide 16 qualified but financially challenged students with funds to enroll as full-time students in the Robotics and Mechatronic Systems Engineering program at UDM. Each student will receive $9000 per year. Seven scholarships will be awarded in the first year and nine in the second. Scholarships will continue for four years, provided the students maintain their eligibility. Therefore, seven and nine students will graduate in the fourth and fifth years of the program

Under this process, the instructor monitors academic concerns,guiding and orienting student training through timely feedback, respect for talent diversity, andactive learning techniques. The process focuses on designing a program for students toprogressively acquire the knowledge required for practical application through activities that mayfacilitate learning and motivate students.Being

Many minors at UWM can be earned with one of the general educationcourses and fifteen additional credits – with proper planning this can be done as part of the 120credit curriculum. Some other minors may need students to take one additional course, but it isstill easier to achieve a combined mechanical engineering major and non-engineering minor withjust one additional course as opposed to five or six additional courses.
