With a base of ideas summarized in the book “How People Learn (HPL)” [1], VaNTHextended HPL’s research base from K-12 education to undergraduate and graduate learning inbioengineering [2, 3]. The four thrusts of HPL are: learner-centered, knowledge-centered,assessment-centered, and community-centered education. The HPL framework only highlightsthe need for these critical dimensions, and does not provide specific details for how tosystematically design instruction to optimize them. VaNTH researchers found challenge-basedinstruction (CBI) to be an effective instructional model for designing learning environments [4,5].

Bygiving early access to specialized pieces of equipment and hands on training early inundergraduate education, allows them to develop innovative ideas that utilize the equipment fortheir projects. Training also allows students to quickly become comfortable with the tools thatelectrical engineering depends on, instead of having to develop their proficiency in the first fiveyears of being in the workforce or graduate school.Introduction:Back in the fifties and sixties there was a significant push for engineering

Moreover,rather than focusing on single interventions, we frame our research holistically to understandhow the variety of potential gatekeepers might be re-positioned or trained to support a morediverse population of students who choose to enroll in postsecondary engineering programs.The overarching research question that we seek to answer is as follows:Where and why are there demographic variations across high schools in the proportion ofstudents who fit an engineering academic profile but do not enroll in an engineering major?We break that question into the following sub-questions:1.

While numerous arguments exist as to why studentsstruggle in these gateway courses, many of the purported reasons are related to either a generallack of appropriate study skills or to the nature of the content itself. Supplemental instructionhas been thoroughly explored as a means to guide students toward developing general studyskills and habits, as it has been asserted that “students who performed well in high school classeswhile exerting minimal effort, may not possess the necessary study

In this study we seek to use dialogue videos to foster interactions between pairs of studentsoutside of the classroom while working on homework in a flipped bio-transport class (fluiddynamics, heat transport, and mass transport). Thus, our research question is: Do dialogue videosenhance learning and foster interaction between students? In each dialogue video, a student/tutee works an example problem while the instructor/tutorassists the tutee and ensures that the tutee thinks out loud.
