project: 1. ShapeOko 2: Presently five ShapeOko 2 desktop CNC machines8 are deployed with two additional ShapeOko 2 CNCs under construction. The ShapeOko 2, shown in Figure 1, is an open source, x-, y-, z-axis, moving gantry design developed by Edward Ford9. An aluminum extrusion MakerSlide10 rail and carriage system is used for both the axis struc- ture and precision motion guide-rails – thereby reducing material use and costs. The drive system comprises a total of four stepper motors (dual motor x-axis). Timing pulleys and belts are coupled to the rail and carriage gantry to generate smooth motions. The ShapeOko 2 can be purchased as individual parts or in several self-assembly kit options from

Each day was closed with the discussion about the experiments and the way howto improve the developed labs.At the end of workshop the assessment of experiments and accompanying applets was done. Theassessment data will be used for improvement of the newly developed course - especially forupdating the hands-on as well as virtual labs.The participants highlighted the positive effect of synergy of educational tools, i.e. “combinedaction” of the two types

providestudents with a more coherent and connected experience with learning engineering design andengineering analysis by facilitating the learning of both design and analysis through a natural,intuitive and portable pen-and-tablet-based system, called „IDEA-Pen‟.The aims of this project are as follows: 1. Enable intuitive creation and manipulation of sketches representing engineering mechanics and kinematics problems, and explore, through critical exploration, structural and kinematic “what-if” scenarios by using finite-element solvers and constraint solvers to run quick simulations. 2. Enable a visual dialogue between the student and teacher, and a collaborative learning environment among students, through easy, intuitive

We call this TDL (Teaching a Developed Lesson). Expect to present one or two TDLs. - Last year’s in-service teachers will give a 1-2 hour lesson that they have changed/modified last year according to their experience from last summer.

As an example, project management skills are often neglected in an engineering orscience curriculum, requiring additional training for those engineers who end up in managementpositions. Skills such as the ability to lead and work effectively as a member of a team arefrequently identified as critical to the success of an engineer, but typically are lacking in newengineering graduates. 1 This article presents some information on impact of the NSF S-STEMon development of students’ professional skills.IntroductionSoft skills are important components of both industry and organizations.

The lack of engineers is especially pronounced amongwomen and minorities—in 2007, only 12% of bachelor’s degrees in engineering were awarded toblack and Hispanic students, and 19% to women3.

The struggles thatmany DHH students face in mathematics as well as general problem-solving skills are well-documented and limit the potential for DHH students to be successful while pursuing careers inSTEM. 1-3Several important findings in DHH research have provided some insight as to why DHH studentslag behind their hearing peers in the development of problem-solving skills. First, DHHstudents, on average, do not possess the same level of conceptual knowledge as their hearingpeers.4-6 As a result, when faced with a problem

Based on existing research, we expect threekey factors to influence ideation flexibility: 1) problem framing (the way a problem and itsconstraints are “set”); 2) the use of ideation tools; and 3) ideation teaming (interactions withothers during ideation). Our research investigates the impacts of these key factors on engineeringideation flexibility and correlates them with students

What practical problems can they be used to solve, andwhy should the students care about any of it? Leading educational theorists agree that thisapproach is not always successful in fostering understanding, synthesis, eventual application ofknowledge, and the ability to use information. A well-established precept of educationalpsychology is that people are most strongly motivated to learn things they clearly perceive aneed to know.1, 2 A preferable alternative is inductive teaching and learning.

The portability of the kit is enhanced by an innovativedesign allowing the kit to be shipped in a flat 2-in-thick box as shown in Fig. 1(left). A fastener-free design allows the kit to be assembled into its operating condition by interlocking threeacrylic plates which interlock when rotated by 45 degrees with respect to the base plate as shownin Figure 1(right). A self-calibrating step during the initialization allows the system toautomatically find the vertical position (origin of the coordinate system). A custom designedcircuit board produces the
