Collaborative Learning And Differentiated Instruction: Applying 1 Thessalonians 5:14 In The Classroom, Shannon L. Capps

Christian Engineering Conference

Increasingly, student-centered, collaborative learning is advocated in the pedagogical literature. Here, the epistemological underpinnings of these approaches are examined. Where these practices are established on principles contrary to God’s revelation, how God’s design for the building up of the church could inform collaborative learning and differentiated instruction is explored.

Specifically, many modern pedagogical techniques arise from constructivist epistemology, which acknowledges not an objective truth but a cognitive failures and successes. Practitioners of these methods are not necessarily complicit in adopting this worldview. Nevertheless, repositioning pedagogical techniques observed to be helpful in practice within a biblical worldview is necessary for discerning …

Pedagogical “Seasoning” For Engineering Class Using Analogy, Message, And Theme In The Story, Hoo Kim, Paul Leiffer, Craig Olson

Redeeming And Sanctifying Engineering Imperfections, Markus D. Ong

Christian Engineering Conference

Comparing God’s designs with engineering designs can help Christian engineers understand both better. Most of the analogies of God as a creative designer focus on extolling the beauty and wonder of the created universe, but this paper aims to take a deeper look at how good design handles imperfection in this world. Although imperfections are ubiquitous, the imperfect can be used. Even the imperfections themselves can be utilized to accomplish the goals of a good designer. This is evident from three different perspectives: a macroscopic view of engineered products, a microscopic view of materials processing, and a “missioscopic” view of …

A Framework For Engineering Analysis And Worship, Timothy A. Wood

Christian Engineering Conference

Engineers work in an objective world, defined by an external reality created by God. As engineers approach problems, they face the difficult challenge of aligning a complicated and unforgiving reality to available analytical engineering and math models. A helpful engineering analysis framework focuses on three models: God’s reality, the engineer’s mental model, and engineering community’s analytical models. The transition between these models structures problem-solving strategy and critical thinking as the engineer restates the problem, plans the analysis, solves the problem, and checks the answer. The framework also engages all three engineering languages (words, sketches, and math) to communicate holistically the …
