This is a questionthat has been addressed previously

These eight elements leadto eight categories of questions present, to some degree, in all critical thinking: (1) what is thepurpose? (2) what is the point of view? (3) what are the assumptions?

The inclusion of disparate knowledge is highlighted in the literature.

Since the pre survey wasconducted during the first 1-2 months of the term, they likely reflect both a messaging differencebetween the alternative and the traditional course, as well as incoming beliefs prior to engagingwith the course.When performing a 2-sample independent t-test, only the contrast between impressions ofprofessional programming practice from the subsequent semester interview showed statisticallysignificant differences between alternative and traditional populations, at a 2-tailed alpha level of0.05 (p=.03)When performing a matched pairs t-test on the students in the alternative class who took the preand post survey, only the survey item “This class consisted of” showed a statistically significantdifference between pre
, there is general agreement that students learn by doing. This is reflected inthe aphorism “Tell me and I forget, teach me and I may remember, involve me and I learn”10[which is often misappropriated to Benjamin Franklin, but likely derived from writing of theChinese Confucian philosopher Xunzi (312–230 BC)]. While it is true that information andequations can be learned by reading, memorization, or listening to someone else speak, these arenot the best methods to build intuition. Intuition is built through experience, learned by doing,and reinforced through practice. The processes of learning and doing are inseparable.6 Thecomplexity of topics taught limits the ability for students to “learn by doing” within the time-restricted classroom setting

However, conceptual understanding of EM phenomena is notindependent of sophisticated mathematical analysis, especially in upper level EM courses13. Inthese situations, the vector nature of the EM fields and the use of abstract operators can make thestudy of EM phenomena significantly more challenging.

We study whether on-lineexaminations are more appropriate for a programming course. The examinations can be takenon-line or on paper in a classroom. Both formats are open-book and open-note and have the sameamount of time. This study considers the following questions: (1) Do students perform better inon-line examinations because they can type, instead of writing, code and have access tocompilers? (2) Do students prefer on-line examinations to traditional paper-based examinations?What are the reasons? (3) How can appropriate technology be used to maintain honesty?

The questions of the quizzeswere on the scientific article but also reflecting on the lectures and the assessment

Facilitate student interest in robotics.Theoretical Motivation The theoretical motivation that drove course redesign was centered on evidence-basedpedagogy pointing towards the benefits of project-based learning. Fundamentally, Kolb’sExperiential Learning Model asserts that a cycle of concrete experience, reflective observation,abstract conceptualization, and active experimentation results in higher student learning [10].Implementation of Kolb’s method along with the integration of theory and hands-on practice inand introductory engineering course at Harvey Mudd College saw a statistically significant gainin student learning and an increased enthusiasm amongst female students [5]. To incorporatethese theories, our
teamwork., most of the time this is done by just throwing students in teams in an ad hoc manner or just letting students form their own teams, resulting in very bad teamwork experiences, especially for the more talented students.To enable students to experience teamwork in a more favorable setting, this paper proposes asystem whereby students are trained to be effective members of a team as well as being effectiveleaders. There are very few activities geared towards similar goal. Notably, Chesney’s [2] workon “students’ reflection on group work” is one such activity. In [2], four 30-minute discussions,Chesney’s so-called “vignettes”, are given in a semester. Similar to the proposal described hereinis the inclusion of a teamwork

While some faculty felt that grades should be primarily focused on projectdeliverables, others thought that more traditional summative evaluations had more value. In thefirst iteration of the course, reported here, the project comprised approximately 40% of the grade,technician training 30%, and in-class work and examinations focused on concepts 30%.As shown above in Figure 1, the three parallel components of the course had some overlap, butaddressed very different learning goals. These learning goals were drawn from an engineeringdesign taxonomy 6 used in the ECE department to evaluate curricular content. Details on each ofthese
say engineers are like dogs: if you throw them a bone they will go and fetch it. This crudeanalogy reflects some of the strong qualities of engineers, like problem-solving (fetching thebone), but it also reflects the fact that someone else has to not only throw them the bone, but mustalso choose which bone to throw. Educational techniques and courses for improving initiative,curiosity, creativity, and grit in engineers are becoming increasingly important to prepare them forthe dynamic working environment they will find after graduation. In this work in progress, weexpose the results of a freshman course that has been organized as a project-based learning (PBL)class. It is different from the traditional PBL approach by the fact that the

Faculty must do more than embed writing assignments into their classes.19 2. The writing assignment must offer students time to receive feedback, reflect on their learning, and revise their drafts. 19,20 3. Writing requires an interactive, coaching pedagogy—like that advanced by How People Learn techniques.19 4. Scaffold complex writing tasks over simple mechanics to promote improvement.16 5.

There will be asummary of some of the assignments used to encourage reflective learning as well as teamworksuch as journals, memos, reports, code, demonstrations and presentations. The course was taughtfor the first time in Fall 2015 quarter and again in Winter 2015 quarter. There will be a qualitativeand quantitative analysis of the learning artifacts in order to identify trends and lessons learned tocontinue improving the course. There will also be a comparison of the student course evaluationsbefore and after the change to the Arduino Uno microcontroller. These results will be presentedin the paper along with

One facilitator noted in her session notes,“An interesting reflection for me during this studio was that my first tendency when workingwith engineering students (especially those that I know in some context) is that I transitioninto being a team member

TheREU Program focused on the developmental and showcase uses. For developmental purposes,their e-portfolios promoted transferable skills, lifelong learning, and reflective thinking [7].
