We chose an oblique rotation method (promax), as this is appropriate in educationaland social science surveys in which some correlation between factors is both anticipated anduseful [29, 30]. The Kaiser-Meyer-Olkin (KMO) [31] measure of sampling adequacy was 0.78,which met the recommendation of ≥ .70 [32] and Bartlett's test of sphericity was significant, p .40 or < -.40); this loading indicates which questions group together as a latentfactor. These factors are retained if they have a Cronbach’s alpha ≥ .70; the factors can then benamed by researchers to reflect the latent construct measured. The

This survey starts as follows: “Your insights into your learning in this course can help me see our course from your side of the desk. Please respond to any three of the statements below (more if you’d like). I will use them as I plan for my courses next semester.” Then students are given the option to choose to answer three out of the six listed questions.Given this option, most students tend to answer in more detail when elaborating their answers. Asummary of student feedback in the end of spring 2022 on these questions are given below: Question 1: “This course most helped my learning of the content when … because …” 77.3

Although there is no definition in theliterature about how many areas should be assessed, it can be observed in this process that mapswere created that reveal the coordinators' appropriation of thecore points of the curriculum and thespecific competences of each area.Furthermore, it also allowed the closest programs to also havemaps that reflect this proximity. It is thus observed the importance, for the implementation of a learning

Kaczala, , Eccles, 2005). Stage 1 associates the codes discovered in stage 0with the four subjective task value (STV) categories outlined by Eccles: (a) accomplishment, (b)intrinsic, (c) utility, and (d) relative cost. The definition of Attainment is how an individual'sview of a task reflects their sense of self. Intrinsic value, also known as interest value, is theenjoyment individuals have while performing a task. Utility value is described as a student'sview of the future involvement of a particular task, and relative cost is the cost associated withengaging in a particular task, as measured by time, effort, or psychological aspects.

For measuring the pressures on the combustion chamber as well as the tanks, straingauges were examined as a possible choice. Strain gauges provide an effective way to measurepressure using hoop stress (3). It should be noted that this measurement is a derivedmeasurement, however the benefits of a strain gauge’s non-intrusiveness far make up for anydownsides at this stage of development at RPL.Data Acquisition System Design Goals The main goal of the DAQ is to be quickly set up and applied to many different prototypedesigns.

Conveying this type of modeling sensitivity to a student using FEA isa challenge.Discussion The following points reflect this mechanical design teacher’s experience withsomeone who does calculations and FEA studies without due consideration of thereasonableness of the estimated stress response. 1) A person should always interpret the results of calculations or simulations forreasonableness. It is not unusual to find engineering students substitute numbers intoequations without questioning the reasonableness of the “solution”. One commoncharacteristic of this situation is inconsistency in the units of

Design is what engineers do, and hence the training should reflect this. Traditionally,design experiences have been relegated to senior year capstone experiences. Recently however,an increase in the number of design experiences in the freshman year, sometimes referred to ascornerstone design experiences, are being introduced into curricula. These design-focusedcourses have taken the form of project-based courses where the structure of the course focusesaround the design of a single or
much enjoyed the guest lectures; it was one of the few times that I learned about how the course material was actually being used in industry. Also, I think the flipped classroom worked well for this course as with programming, questions tend to arise when you are working on an activity rather than learning the syntax. • The guest lectures and seeing industry applications of Python in chemical engineering are very enjoyable. I was doubtful about the structure where videos were posted for watching outside of class and activities were given during class time, but upon reflection I think it was probably the best way to learn the material. • Flipped classroom and in class assignments that we can ask for help
the on-line approach, both asynchronous and synchronous deliveryoptions were available to accommodate the range of activities undertaken, including readings,teacher contributions to discussion, and completion of assignments by teachers. Discussionforums allowed teachers to share content, ideas, instructional strategies, and alternativeperspectives. As part of the project, teachers implemented and maintained electronic portfolios,that included lesson plans and samples of student work, especially those for “observed classes”either by videotape, through the web, or live. Teachers were also asked to reflect upon theirimplementation of the lesson plans, describing successes and problem areas that occurred duringthe implementation. At an

Every year, each participating federal agency compiles,ranks, down selects, and publishes a list of desired STEM-based innovations that are alignedwith its societally significant mission but which are not commercially available. Each agencyalso publishes instructions on how to apply for SBIR funding, how applications are evaluated,abstracts of previous awards (the proposals themselves are confidential), and award statistics.The number of solicited innovations, called “topics” in SBIR parlance, has increased from 842 in2011 to over two thousand in 2018 (United States Small Business Administration, 2021).

We investigated the structure of optical fiber interferometers not onlyfor optical fiber filters design but also for exploring a framework for a new digital filter synthesis.Since the single mode optical fiber has an extremely high bandwidth and very low attenuationtransmission medium, a short time-delay bandwidth can be realized. Thus, we proposed this newapproach for designing digital filters based on the single mode optical fiber.

In general, their task allocation software can be improved in afew different ways by integrating real-time data, improving the flexibility of the algorithm, andenhancing communication and collaboration between tasks. Integrating real-time data would bedone during the implementation of their task structure on a real UAV-UGV robotic team. To applysuch a feature, the robotic team would need to collect data through sensors and/or cameras, transferthe data to a central system so it can be processed, make a decision based on the processed data,constantly update the data to reflect changes in the environment, and finally store the processeddata. The advantage of real-time data is that the software can better understand its

These methods are summarized below.1) Combine synchronous and asynchronous learning options to provide both flexibility for self- paced learning and humanized interactions in the class. [10]–[13]. All the course materials, schedules, and assignments were managed using iLearn. Weekly pre-recorded lectures, usually composed of two or three 30- to 50-minute videos, were posted to iLearn as shown in Figure 2(a). At the end of each video lecture, exercises were added to reflect the topics covered in the video. A shared Google doc was created to collect questions from the students on the video lectures. The weekly video lectures were designed tailored to the weekly lab activities. Students must watch

In these cases, classroom students were addedto a virtual team temporarily, then returned to the physical classroom when able. The logistics ofmanaging shifting participation was somewhat complicated, but students overwhelminglyappreciated the option to elect their participation preference, as reflected in end of semesterevaluations and comments.One instructor observed a notable increase in quantitative evaluation of teaching effectivenesswith this course, as measured by end of semester surveys administered by the university.Though there is no data for past semesters (this was the
