deoxygenated hemoglobin (deoxy-Hb), also called blood oxygenation leveldependent (BOLD) response. BOLD response is a proxy for brain activity [13]. An increase inoxy-Hb typically mirrors neuronal activity and implies the allocation of resources and nutrientsby the cerebrovascular system [14]. fMRI also measures the BOLD response. The benefit offNIRS compared to fMRI is participants can perform tasks sitting at a desk rather than inside of alarge tube laying on their backs. fNIRS was preferred over EEG because of the spatial resolutionof the data. The fNIRS cap is shown in Figure 1(a). Changes in oxy-Hb were measured using thefNIRS in 22 channels placed in the 10-20 system along the prefrontal cortex (Figure 1(b)). (a

Along with current efforts being made to increase diversity in engineeringeducation programs and the engineering workforce on national and international scales, U.S.military students are increasingly recognized in the research literature as a potential source ofdiverse engineers. With the understanding that military students are not a single monolithicgroup, we frame this review by defining our target population of “military students” as post-secondary undergraduates enrolled at civilian institutions of higher education who a) havecompleted their service and are now military veterans or b) are concurrently serving in the U.S.Armed Forces, such as in the Reserves or National Guard, while attending

the details necessary for any instructor to facilitate this project in order toenhance student learning of dimensional analysis in their engineering fluid mechanics course.The Problem StatementThe inspiration for the problem statement comes from a typical dimensional analysis homeworkproblem that is often posed in undergraduate fluid mechanics textbooks. An example of such aproblem statement is as follows [7]: “A spar buoy has a period 𝑇 of vertical (heave) oscillation that depends on the waterline cross-sectional area 𝐴, buoy mass 𝑀, and fluid specific weight 𝛾. How does the period change due to doubling of (a) the mass, and (b) the area?”While this is a perfectly acceptable problem statement for a homework assignment, we can
earlierwork by Alzahrani [11], who performed a comparison between C++ and Python, but on smallerhomework problems. They too found no evidence of reduced Python struggle, and in fact foundthat Python students struggled more on those small homework problems, even when controllingfor classes targeting majors or non-majors, and for university type.Given that our results indicate that student struggle may not be driven by the programminglanguage, we propose two other factors that contribute to a large share of student struggle, basedon our observations. The first is students struggling to achieve correct program logic. Forexample, to find the minimum of three numbers a, b, and c, one approach with correct programlogic is to write:max = aif b > max

Eitherthey made mistakes in reporting answers or participants from the same team differed in theirdefinition of role rotation. The ambiguity in defining role rotation is more likely whenconsidering their statements on what led them to assume the role(s) they have had.

guidelines, theimplementation of integrated STEM education comprises a broad range of approaches [5].Because of this, it is essential to understand the ways teachers use integrated STEM approachesin their instructions. Such teaching experiences will provide valuable perspectives on how STEMintegration is represented in practice. Thus, the goal of this study is to examine how anelementary school teacher enacted STEM integration in her science classroom. Specifically, thisstudy aims to answer the following research questions: a) In what ways does an elementaryteacher make connections between different STEM disciplines?, b) How did contextualintegration manifest in her integrated STEM implementation?, c) How did content integrationmanifest in her
