SoTL Best Practices: 21st Century College Students’ Perceptions of Learning Styles and Instructional Design Materials’ Influence on the Successful Completion of Assignments
There is a long history of interest in individual differences in learning styles. Beginning in the 1960s, academic research endeavors began examining the concept of personalizing teaching as the best scholarship of teaching and learning best practice (SoTL). This current series of interconnected empirical studies take a fresh look at SoTL by examining students’ self-perception of their learning styles and whether their perceptions relate to how they learn. Today’s college students are growing up in the information age of the 21st Century. Many educators believe that a best practice is to focus on delivering personalized instructional material through technology. Thus, the current mixed methods study adds value to SoTL research by examining these concepts through a representative sample of the subject university in the United States. To assure the reliability and validity of the complex series of three integrated studies, research assistants were trained by a researcher experienced in experimental and survey designs. Data were analyzed using SPSS27®. The study\u27s findings indicated that focusing instructional materials on individual learning styles does not equate to learning success; in fact, the data showed no relationship. The data showed that a combined instructional delivery methodology (kinetic and audio) had a positive influence on learning success. The findings revealed that explicit instructions with or without audio were the most effective in leading to students’ ability to follow instructions successfully. Managing students’ self-perceptions of learning styles is important to assure successful learning experiences. Findings, conclusions, implications, recommendations, and limitations are presented herein
Henry Versus Thompson Approach for Fixation of Proximal Third Radial Shaft Fractures: A Multicenter Study
Objective:
To compare the volar Henry and dorsal Thompson approaches with respect to outcomes and complications for proximal third radial shaft fractures.
Design:
Multicenter retrospective cohort study.
Patients/Participants:
Patients with proximal third radial shaft fractures ± associated ulna fractures (OTA/AO 2R1 ± 2U1) treated operatively at 11 trauma centers were included.
Intervention:
Patient demographics and injury, fracture, and surgical data were recorded. Final range of motion and complications of infection, neurologic injury, compartment syndrome, and malunion/nonunion were compared for volar versus dorsal approaches.
Main Outcome:
The main outcome was difference in complications between patients treated with volar versus dorsal approach.
Results:
At an average follow-up of 292 days, 202 patients (range, 18–84 years) with proximal third radial shaft fractures were followed through union or nonunion. One hundred fifty-five patients were fixed via volar and 47 via dorsal approach. Patients treated via dorsal approach had fractures that were on average 16 mm more proximal than those approached volarly, which did not translate to more screw fixation proximal to the fracture. Complications occurred in 11% of volar and 21% of dorsal approaches with no statistical difference.
Conclusions:
There was no statistical difference in complication rates between volar and dorsal approaches. Specifically, fixation to the level of the tuberosity is safely accomplished via the volar approach. This series demonstrates the safety of the volar Henry approach for proximal third radial shaft fractures
CFD modelling of Close-Coupled Gas Atomisation (CCGA) process by employing the Euler-Lagrange approach to understand melt flow instabilities
This paper presents a CFD analysis of the melt and flow-field instabilities in a close-coupled gas atomisation process (CCGA) caused by the gas–melt interactions. The melt mass flow is coupled to the atomiser internal pressure, which varies over time due to the unsteady flow field. A two-phase flow of Argon gas and melt particles is modelled using a coupled Euler-Lagrange framework. Three different initial gas-to-melt ratios (GMRs) of 5.5, 2.6 and 1.32 are considered to study the gas–melt interaction. The results show that in the case GMR = 1.32, sustained instability both in the melt and in the flow-field are distinctly observed, resembling physical atomisation process. This melt fluctuation corresponded to an alternating flow-field fluctuation; alternating between open- to closed-wake condition, where the local maxima of the melt corresponded to an open-wake condition, and the local minima of the melt corresponded to a closed-wake condition
