The U.S. workforce is increasingly comprised of older adults, women, and minorities who lack basic skills and are unable to acquire these skills through traditional educational and training programs. New approaches are needed to provide effective training to the adult learner and flexible support for nontraditional students who must balance work-life demands with limited educational opportunities. Contextualized teaching and learning (CTL) is a form of experiential learning that blends both basic skills and occupational training together in environments that allow students to relate subject matter to real-world situations. Virtual CTL environments can be created to better engage students, provide immediate performance feedback, reduce training time, and improve accessibility. To determine the effectiveness of CTL, the Society of Manufacturing Engineers Tooling U curriculum and learning management system (LMS) was studied. This intervention consisted of online modules with basic skills remediation blended with interactive labs and virtual reality exercises. A nonrandom population of 342 participants was chosen for study, including 75 exposed to the CTL intervention (experimental group) and 267 not exposed to the CTL intervention (control group). Learning outcomes such as test scores, completed credit hours, course completions, and earned credentials, were compared between CTL and non-CTL groups and between demographic subsets within the CTL group. Underrepresented groups, including older adults, women, and minorities, were 2 to 3 times greater in the CTL group compared with the non-CTL group. Overall, students exposed to CTL achieved higher rates of credentialing (55%) when compared with students not exposed to contextualized instruction (20%).

Purpose This paper aims to examine general contractors’ experiences of using off-site manufactured structural framing systems. This engaged a single-case study using a qualitative methodology to identify expected benefits, actual benefits and challenges of such systems. Design/methodology/approach A single-case study approach evaluated general contractors’ experience of using a manufactured structural framing system. Qualitative data were collated and analyzed from industry domain experts to determine commonalities and thematic thinking. Findings The study revealed that the reasons behind considering off-site building systems were: accelerating the project schedule, overcoming site constraints and having a better end-product. The top expected benefits were: saving time (schedule), saving cost and improving quality. The top actual observed benefits were: saving erection time, reducing waste generation, reducing project costs, reducing safety risks and improving construction site logistics. The main challenges encountered were: unfamiliarity of different project parties with the off-site framing system, difficulty with reducing the overall project schedule, heavy site logistics and complicated off-site system design and standards requirements. The findings include solutions to overcome the challenges associated with using a manufactured structural system. Research limitations/implications This paper was a case study and therefore inherently limited in its generalizability. The study was conducted with general contractors in the mountain-west region of the USA. However, the implications of the study may have a broad application, as contractors across the globe seek to find similar solutions to using off-site or manufactured construction methods. Practical implications Construction labor shortages around the world are forcing the construction industry to find creative solutions to meet the demand for their services. Manufactured or off-site construction methods provide a possible solution to that labor shortage. However, builders need to be aware of the immediate challenges and actual benefits of using a manufactured structural framing system. Social implications Manufactured structural framing systems have the potential to impact lean and sustainable practices in construction. Reduced waste, reduced on-site man-power requirements, reduced construction schedules and reduced injuries each improve the lives of construction workers and the communities around these buildings. Originality/value An extensive literature review was performed to guide the design of this case study. Much has been written about off-site construction practices, but there is a significant research gap on the topic of structural framing systems. This study contributes to expanding the knowledge of off-site construction and specifically helps researchers and practitioners understand the challenges and benefits of this systematic approach to construction.

Purpose Despite economic growth in the construction sector of the USA, profit margins are persistently low. An examination of collection practices of over 400 construction firms revealed a high number of firms with a collection period ratio above 30 days. This study aims to examines the variance between collection period ratio (days in accounts receivables, DAR) and days in accounts payables (DAP) and its correlation with profitability ratios [e.g. gross profit margin (GPM) and net profit margin (NPM)]. Design/methodology/approach Descriptive statistics were used to observe trends over three years of financial reporting (2013 through 2016), while correlation statistics were used to understand relationship or association between the different financial ratios and the collection period variance (CPV). Respondent firms were stratified by the North American Industry Classification System, company type and revenue size. Findings Conventional theory holds that increasing financial expenses because of collections negatively impacts profitability. Therefore, the hypothesis of the study suggested a statistical correlation between the CPV and profitability measures. Results of the study, however, supported the null hypothesis. Reasons for the lack of correlation are considered as well as necessary follow-up studies before rejecting the hypothesis. Originality/value No such study was found specific to the construction industry, and as such, this study contributes to better understanding the implications of extensive collection periods. Further, this study contradicts assumptions about the behavior of the construction industry and the causal relationship between extensive collection periods and profitability.

Graduate education can be utilized by working professionals as an advancement to their careers. This paper presents the results of a Delphi survey sent to 31experts in the construction industry. A survey questionnaire was developed to ask the participants about their perceptions of the relevance of the current graduate-level construction management courses in developing senior-level construction managers. A curriculum analysis of 34 graduate CM programs in the United States was conducted. The resulting data from the curriculum analysis is utilized in developing the survey questionnaire. The study is part of a larger research Delphi study that aimed at identifying the Knowledge, Skills, and Abilities required for senior-level managers in the construction industry. Two phases of the survey were sent to participants in this Delphi study. The results of the study indicate that the current graduate programs in construction management across the United States of America are not adequately focused on developing senior-level construction managers.
