Advancements in computer technology have revolutionized extended reality (XR) experiences, including augmented reality (AR), virtual reality (VR), mixed reality (MR), and 360° photography and videography. These technologies have found widespread adoption in various educational contexts, from K-12 schools to universities. However, community and technical colleges in the United States have been slower to adopt these innovative instructional modalities. This study aims to investigate the factors influencing the adoption of XR technologies at 2-year institutions, guided by the consolidated framework for implementation research (CFIR). A qualitative research approach was applied by interviewing 13 educators from 2-year colleges to identify their perception and the challenges faced while implementing XR-enabled instruction. Limited availability of XR educational content, restricted development opportunities of XR content, limited integration of these technologies with existing learning management systems, resource constraints and training needs of educators are some of the factors that hinder implementation of these technologies at 2-year colleges. 

Protection against airborne viruses has become very relevant since the outbreak of SARS-CoV-2. Nonwoven face masks along with heating, ventilation, and air conditioning (HVAC) filters have been used extensively to reduce infection rates; however, some of these filter materials provide inadequate protection due to insufficient initial filtration efficiency (FE) and FE decrease with time. Flat sheet porous membranes, which have been used extensively to filter waterborne microbes and particulate matter due to their high FE have the potential to filter air pollutants without compromising its FE over time. Therefore, in this study, single layer polysulfone (PSf) membranes were fabricated via non-solvent induced phase separation (NIPS) and were tested for airflow rate, pressure drop and FE. Polyethylene glycol (PEG) and glycerol were employed as pore-forming agents, and the effect of the primary polymer and pore-forming additive molecular weights (MW) on airflow rate and pressure drop were studied at different concentrations. The thermodynamic stability of dope solutions with different MWs of PSf and PEG in N-methylpyrrolidone (NMP) at different concentrations was determined using cloud-point measurements to construct a ternary phase diagram. Surface composition of the fabricated membranes was characterized using contact angle and X-ray photoelectron spectroscopy (XPS), while membrane morphology was characterized by SEM, and tensile strength experiments were performed to analyze the membrane mechanical strength (MS). It was observed that an increase in PSf and PEG molecular weight and concentration increased airflow and decreased pressure drop. PSf60:PEG20:NMP (15:15:70)% w/w showed the highest air flow rate and lowest pressure drop, but at the expense of the mechanical strength, which was improved significantly by attaching the membrane to a 3D-printed polypropylene support. Lastly, the FE values of the membranes were similar to those of double-layer N95 filters and significantly higher than those of single layer of N95, surgical mask and HVAC (MERV 11) filters. 

During the Fall 2018 semester, two community colleges and one university shared their design and additive manufacturing (AM) facilities and capabilities. While student teams learn the depth of technical drafting in one community college’s design course, the other two institutions have opened the doors of their AM labs so that students can solidify the knowledge they acquire which is largely limited to the computer screen in their design course. As the design files are received by the AM labs of the other two institutions, the files are evaluated for AM related issues and modifications are suggested. Following any revisions, the AM labs begin production of the files, both in single version and batch production for potential, larger volume applications while demonstrating to the students and stakeholders the versatility and cloud manufacturing capabilities that AM has to offer on a variety of levels, as well as helping to improve the student’s design competencies that are necessary for AM. This current paper will report the nature of the current AM coalition and share a sample student project designed and produced during the Fall 2018 semester. The feedback received from the students will also be shared.
