Developing My Perspectives on Scaffolding and Problem-Based Learning: A Retrospective View

In this paper, I describe the iterative development of my perspectives on scaffolding and problem-based learning through interactions with other scholars and research. Such influences include doctoral experiences, funded projects, and exposures to research from a variety of traditions

Clinical Practice Guideline on Evaluating the Effectiveness of Venipuncture Arm Simulation

Venipuncture is an integral process in clinical care, and it has an indispensable role in diagnostics and determining therapeutic interventions. The process of phlebotomy has faced several challenges that have compromised patients’ safety. The risk of incorrect venipuncture, or preanalytical errors, leading to severe patient complications of hematoma and thrombosis calls for training using current, evidence-based practices. The goal of this project was to develop a clinical practice guideline (CPG) to determine the efficacy of venipuncture simulation training using an arm task trainer to enhance the phlebotomy skills of nurses. Based on the outcome, present, state, test model and Nightingale’s theory of nursing, in this project a CPG was developed that focused on enhancing venipuncture simulation and improving the practice in nursing to reduce analytical errors. A team of multidisciplinary experts reviewed the CPG using the Appraisal of Guidelines for Research and Evaluation Evaluative II tool. The findings, based on the tool’s six domains, showed the phlebotomy content experts’ evaluations of the CPG’s scope and purpose, stakeholder involvement, rigor of development, and clarity. The results indicated that the CPG generally had room for improvement, with growth opportunities regarding information on the rigor of development, the clarity of presentation, applicability, and editorial independence. The quality domain scores ranged between 31% to 64% with a mean domain score of 52.1%. The CPG was rated as needing some refinement, with 100% of the expert panelists recommending use of the guideline with modification. Application of the evidence-based practice of using the CPG has the potential to improve patient outcomes, which is a positive social change

Implementation of a Conflict Mediation Program in an Elementary School

Schools are looking at how violence in the school contributes to students\u27 stress levels and how it interferes with the academic abilities and performance of students. If schools are to be orderly and peaceful places in which high quality education can take place, students must learn to manage conflicts constructively. Studies show that conflict mediation plays a role in creating an environment where students regulate their own behavior in regards to conflict in school. This research study surveyed students about their attitudes and opinions towards conflict mediation at Beaver Lake Elementary School. This study also evaluated whether staff to student disciplinary contacts decreased after the implementation of the conflict mediation program

The 7-channel FIR HCN Interferometer on J-TEXT Tokamak

A seven-channel far-infrared hydrogen cyanide (HCN) laser interferometer has been established aiming to provide the line integrated plasma density for the J-TEXT experimental scenarios. A continuous wave glow discharge HCN laser designed with a cavity length 3.4 m is used as the laser source with a wavelength of 337 {\mu}m and an output power up to 100 mW. The system is configured as a Mach-Zehnder type interferometer. Phase modulation is achieved by a rotating grating, with a modulation frequency of 10 kHz which corresponds to the temporal resolution of 0.1 ms. The beat signal is detected by TGS detector. The phase shift induced by the plasma is derived by the comparator with a phase sensitivity of 0.06 fringe. The experimental results measured by the J-TEXT interferometer are presented in details. In addition, the inversed electron density profile done by a conventional approach is also given. The kinematic viscosity of dimethyl silicone and vibration control is key issues for the system performance. The laser power stability under different kinematic viscosity of silicone oil is presented. A visible improvement of measured result on vibration reduction is shown in the paper.Comment: conference (15th-International Symposium on Laser-Aided Plasma Diagnostics

Scaffolding for Optimal Challenge in K–12 Problem-Based Learning

Establishing optimal challenge enhances intrinsic motivation, interest, and the probability of success in the learning activity. In K–12 problem-based learning (PBL), students may struggle to address associated tasks that are beyond their current ability levels. This paper suggested learner-centered scaffolding systems (LSS) to improve K–12 students’ perception of optimal challenge by addressing their learning issues in PBL. LSS enhances students’ experience in autonomy and competence by providing multiple types of scaffolding in accordance with students’ different needs and difficulties in PBL. Students can control the nature and frequency of scaffolding by themselves according to their needs and ability, and it plays a role in improving their self-directed learning skills. Last, peer scaffolding between students with similar abilities satisfies students’ needs for relatedness

Comparison of Homework Systems (Four Web-Based) used in First-Semester General Chemistry

Web-based homework systems are becoming more common in general chemistry as instructors face ever-increasing enrollment. Yet providing meaningful feedback on assignments remains of the utmost importance. Chemistry instructors consider completion of homework integral to students' success in chemistry, yet only a few studies have compared the use of Web-based systems to the traditional paper-and-pencil homework within general chemistry. This study compares the traditional homework system to four different Web-based systems. Data from eight, semester classes consisting of a diagnostic pre-test, final semester grades, and the number of successful and unsuccessful students are analyzed. Statistically significant results suggest a chemistry instructor should carefully consider options when selecting a homework system
