labPart A: Half-wave Rectifier CircuitIn the first part of lab, students learn about the half-wave rectifier circuits input and outputresponses with three different load conditions: A) The load is only a light bulb, B) The load isthe motor that they build, and C) The load is the light bulb parallel to the motor.A 3D printer box was provided for the four diode installations in rectifier circuits, as shown inFigure 4. This box increases the safety of the lab environment. This approach offers a superioralternative to traditional breadboards, which may not provide adequate protection againstaccidental contact with diodes. Students apply a half-wave rectifier circuit in Fig 4. a, where theload is only a light bulb, and measure the input and output
students, the challenge should be relevant and simulate an actual situationin the professional field they are pursuing; b) Through the solution, students develop the desiredlevel of competency mastery, and c) students should realize that to generate a solution, they needthe disciplinary knowledge provided in the course. Our educational model delivers this in whatwe call a learning block [1].In this contribution, we present the design of the Modeling the Movement courses as the contextof this study. We describe the methodology and report an overview of students' perception of thecourse in general, each of the modules, and the challenge. We discuss the results highlighting theaffordances of the course design and the areas for improvement.Context of

There were four types of elastic tubes that were provided to the students,each color can be associated to a specific level of resistance: a) The minimum resistance –yellow one b) Low-intermediate resistance – blue one c) Upper-intermediate resistance – redone, and d) The maximum resistance – black one, according to the manufacturer. Thepurposed activity can be divided into four stages: pre-class, during class, post-class, andstudent´s perception. The pre-class and post-class activities (equal for both phases) involveda quiz about elastic force and energy. This quiz included

, featuring a circuit configuration where a 12-volt battery isconnected to two bulbs arranged in series. However, a switch located at point A remains open. Inthis scenario, students are tasked with comprehending that an open switch prevents any currentflow within the circuit. The problem prompt requests explicitly the determination of the potentialdifference between points A and B. Given that point B is directly linked to the negative terminalof the battery, while point A is directly connected to its positive terminal, the potential differencebetween points A and B equates to the battery's voltage, which is 12 volts.To grasp this concept, students must recognize that the potential difference across its terminals iszero in the absence of current flow
, (b) demonstrating the relevance of course content to their future careers, and (c)improving their professional networks by requiring them to connect with a professional. To complete the assignment, students teamed up in small groups (of two or three) andidentified a job that they could imagine pursuing directly after their studies. They investigateddetails about the job, e.g., typical work, salary, opportunities for remote work, work-life balance,and next professional steps beyond this job. They then connected with someone working in thisjob (or in a very similar position) to conduct an informational interview. Again, specificinformation was required: what they typically do, what they like most/least about their job, andwhat their

on this positive interest from students, a committee of faculty who taught in math andsciences was convened to develop the program. Because of the institution’s historical strengths inthe sciences, the committee recommended that the institution offer a B. S. in EngineeringScience, which was subject to the same ABET criteria as B.S. programs in Engineering andEngineering Physics.[7] It was also believed that the program named Engineering Sciencewould be better accepted at a liberal arts institution where a degree such as engineering might beviewed by some as a strictly vocational major. The intent of the degree to equip students with abroad and general engineering background also reflected key principles of the liberal artsapproach.The

building a CAT platform begins with the calibration of item parametersand the estimation of person parameters, following the principles outlined in various ItemResponse Theory (IRT) models [31,32]. These models involve one to four parameters that describecharacteristics of logistic curves. For instance, three-parameter (3PL) IRT models describe thelogistic curve using three item parameters, 'a', 'b', and 'c'. The 'a' parameter represents itemdiscrimination, the 'b' parameter represents item difficulty, and the 'c' parameter represents theguessing parameter, along with person parameters represented by 'θ' for ability1 as a latent trait. Parameters for each item are initially calibrated through pretesting where large numbers ofstudents answer

The interaction radius R is also mirrored on theopposite side, which is why particles at the other end of the simulation area also affect thebehavior of the particle approaching the boundary [9].Boids modelThe boids model, created by Craig Reynolds [5], is based on three basic rules of behavior thatare assigned to each individuum in the swarm: separation, alignment, and cohesion.

How does the classroom observation protocol for undergraduate STEM (COPUS) assess the level of instructor-student interaction?Experimental Concept and Theoretical BackgroundThis study was designed with the application of a hands-on kit consisting of a pendulum bob,retort stand with clamp, string, and portable stopwatch for the ECP mode, while the traditionalmode (non-ECP) consists of Logger Pro software, retort stand, pendulum bob, string, and aPhotogate for sensing the bob’s motion. This experiment focuses on the determination ofacceleration due to gravity and how the bob string’s length depends on the period of oscillationof a simple pendulum experiment.

Our team was brought together in Cornerstoneof Engineering 1 and 2, an accelerated introduction to engineering course at our university, by theinspiration to conserve energy using these concepts. The team, students pursuing degrees inchemical, mechanical, and electrical engineering, aimed to design a device that would utilize theenergy generated from everyday practices that are otherwise wasted. We focused on conservingenergy in the game of basketball, a high-energy and globally popular sport. The goal was to designand build a device
