Netpoint®, Purdue Ect Team

ECT Fact Sheets

The vast majority of construction scheduling software uses a combination of spreadsheets and Gantt charts for developing and depicting Critical Path Method (CPM) schedules. While this paradigm works for the expert scheduler, it is not conducive to collaboration, and it is prohibitively difficult for non-scheduling experts to understand.

NetPoint® provides a dynamic, visual interface conducive to touch and gestural input. Activities are drawn directly on a time-scale and may be placed on the same row or arranged automatically using codes or the WBS. Such control of the presentation makes it easier to communicate the plan to any type of audience ...

Fluid Isolator, Purdue Ect Team

ECT Fact Sheets

The reliability of concrete infrastructure is vital to ensuring daily life, as well as commerce, can progress without interruption. From the pavement of interstate highways to the driveways and sidewalks in a local neighborhood, concrete is expensive to install and often even more expensive, and intrusive, when it needs to be replaced. Unfortunately, to maintain functionality in winter climates concrete is heavily exposed to deicing salts. This not only affects the roads, driveways, and sidewalks where salt is applied directly, but many other areas such as parking and residential garages where vehicles (and people) will track salt along with water ...

Scaffolding To Improve Reasoning Skills In Problem Formulation, John K. Jackman, Sarah M. Ryan, Craig A. Ogilvie, Dale Niederhauser

Craig Ogilvie

Scaffolding to Improve Reasoning Skills in Problem Formulation Abstract Educators in engineering and science disciplines are well aware of student difficulties in formulating problems. Correct problem formulation is a critical phase in the problem solving process because the solution follows directly from the formulation. Students in this phase are engaged in reasoning and argumentation activities that result in support for a specific formulation. Empirical evidence from our work in ill-structured STEM problem solving indicate that more research is needed to understand the nature of problem formulation and what the cognitive challenges are for STEM students. Students work in teams to ...


Flipping A Graduate-Level Software Engineering Foundations Course, Hakan Erdogmus, Cécile Péraire 2017 Selected Works

Flipping A Graduate-Level Software Engineering Foundations Course, Hakan Erdogmus, Cécile Péraire

Cécile Péraire

Creating a graduate-level software engineering breadth course is challenging. The scope is wide. Students prefer hands-on work over theory. Industry increasingly values soft skills. Changing software technology requires the syllabus to be technology-agnostic, yet abstracting away technology compromises realism. Instructors must balance scope with depth of learning. At Carnegie Mellon University, we designed a flipped-classroom course that tackles these tradeoffs. The course has been offered since Fall 2014 in the Silicon Valley campus. In this paper, we describe the course's key features and summarize our experiences and lessons learned while designing, teaching, and maintaining it. We found that the ...

Ecosystem Food Web Lift-The-Flap Pages, Dana L. Atwood-Blaine, Audrey C. Rule, Hannah Morgan

Journal of STEM Arts, Crafts, and Constructions

In the lesson on which this practical article is based, third grade students constructed a “lift-the-flap” page to explore food webs on the prairie. The moveable papercraft focused student attention on prairie animals’ external structures and how the inferred functions of those structures could support further inferences about the animals’ diets. In general, most students made simple causal connections between an animal’s observable characteristics and the food it would probably eat. Some students were also able to make multi-agent connections to develop a more complex mental model of a food web. Ultimately, the lift-the flap project was engaging to ...
