Since being introduced by Connor and Simberloff in response to Diamond's assembly rules, null model analysis has been a controversial tool in community ecology. Despite being commonly used in the primary literature, null model analysis has not featured prominently in general textbooks. Complexity of approaches along with difficulty in interpreting…

Collaborative problem solving (CPS) is a critical competency in a variety of contexts, including the workplace, school, and home. However, only recently have assessment and curriculum reformers begun to focus to a greater extent on the acquisition and development of CPS skill. One of the major challenges in psychometric modeling of CPS is…

Meta-analyses are typically used to estimate the overall/mean of an outcome of interest. However, inference about between-study variability, which is typically modelled using a between-study variance parameter, is usually an additional aim. The DerSimonian and Laird method, currently widely used by default to estimate the between-study variance,…

With memory encoding reliant on persistent changes in the properties of synapses, a key question is how can memories be maintained from days to months or a lifetime given molecular turnover? It is likely that positive feedback loops are necessary to persistently maintain the strength of synapses that participate in encoding. Such feedback may…

Debriefing, the reflective activity following an experiential learning exercise, has been identified as the most important part of simulation learning and is also important for learning in other activities utilized in nursing education. There is general agreement that debriefing provides learning and improves performance. However, there is little…

The prospective use of low fidelity simulation and gaming in aviation training is high, and may facilitate individual, personal training needs in usually asynchronous training setting. Without direct feedback from, or intervention by, an instructor, adaptivity of the training environment is in high demand to ensure training sessions maintain an…

Many chemistry laboratory exercises follow a given protocol with known results. Such traditional laboratories rarely give students an accurate representation of how research is conducted, the scientific practices involved in research, and the ownership that accompanies developing and carrying out an independent project. Several laboratory reforms…

The use of individual patient data (IPD) in network meta-analysis (NMA) is becoming increasingly popular. However, as most studies do not report IPD, most NMAs are performed using aggregate data for at least some, if not all, of the studies. We investigate the benefits of including varying proportions of IPD studies in an NMA. Several models have…

Estimating treatment effects for subgroups defined by posttreatment behavior (i.e., estimating causal effects in a principal stratification framework) can be technically challenging and heavily reliant on strong assumptions. We investigate an alternative path: using bounds to identify ranges of possible effects that are consistent with the data.…

Curriculum-Based Measurement of Oral Reading (CBM-R) is often used to monitor student progress and guide educational decisions. Ordinary least squares regression (OLSR) is the most widely used method to estimate the slope, or rate of improvement (ROI), even though published research demonstrates OLSR's lack of validity and reliability, and…

This article is based on findings arising from a large, two-year EU project entitled "Creating Machinima to Enhance Online Language Learning and Teaching" (CAMELOT), which was the first to investigate the potential of machinima, a form of virtual filmmaking that uses screen captures to record activity in immersive 3D environments, for…

Single-period inventory models with uncertain demand are very well known in the business analytics community. Typically, such models are rule-based functions, or sets of functions, of one decision variable (order quantity) and one random variable (demand). In academics, the models are taught selectively and usually not completely. Students are…

Due to the changing landscape of K-12 education in the United States, particularly issues arising from funding, safety, accessibility, and standardization, the frequency at which teachers utilize traditional field trips has diminished over the last few decades. Thanks to continued advances in communicative technology, however, teachers are able to…

Educational methods should be continuously evaluated. In this study, the views, perceptions and recommendations of undergraduate nursing students with regard to a screen-based computer simulation are defined. This was a qualitative research study. Two focus group interviews were conducted. The students said that the simulation was beneficial for…

This mixed-method study explored the changes in Turkish EFL learners' reported willingness to communicate and communication anxiety after conducting ten real-life tasks in a virtual world. Sixty-five university EFL learners (experimental = 30; control = 35) participated in this study. The participants were the first-year students of a foreign…
