Research Papers
Engineering students often learn by retracing pre-calculated given solutions of tasks and try to understand this problem-solving way. This reconstruction is not always successful in solving new types of problem via modified tasks (Rossow 2008). Every mechanical exercise follows the same solution methodology (Müller-Slany 2018). Applying this basic problem-solving structure correctly is a Pre-condition for solution’s reflection and is therefore essential for teaching. To improve these competencies a strategy training is implemented in exercise-settings in Technical Mechanics (TM).

Tool edge radius plays a significant role in affecting the surface integrity of machined products. The vast majority of existing research, however, takes no account of the effect of tool edge radius in the evaluation and modeling of machined surface roughness, an essential indicator of surface integrity. The present study fills this important research gap and has performed a total of 45 turning experiments on Unified Numbering System (UNS) A92024-T351 aluminum alloy with carefully selected cutting tools with three levels of tool edge radii. This article describes the experimental setup and measurements of tool edge radius and machined surface roughness. …

An Operationalized Model For Defining Computational Thinking, Tony A. Lowe, Sean B. Brophy
School of Engineering Education Graduate Student Series
The Computational Thinking (CT) conceptual framework is entering its second decade of research yet still lacks a cohesive definition by which the field can coalesce. The lack of clear definition makes assessment tool challenging to formulate, pedagogical efforts difficult to compare, and research difficult to synthesize. This paper looks to operationalize differing definitions of CT enhancing the ability to teach then assess the presence of CT. Expanding upon CT definitions, industry practices and processes, and educational theory, we link existing concepts and propose a new element to model an active definition of CT as a theoretical framework to guide future …

The article presents cost-effective materials for elementary classrooms that allow students to create models. These materials include card stock, clay, cable or zips ties, fasteners and bolts, and commercially manufactured building kits such as LEGOs, Erector Sets, Tinkertoys and K'Nex. In addition, the author asserts the importance of using such materials in promoting student learning of technology and engineering.
