The Relationship Between Double Dosing and Middle School Math Student Achievement

This study examined the following research question: Is there a significant difference in math performance between the total sample of below grade level 6th, 7th, and 8th grade students engaged in double dosing and the sample of below grade level 6th, 7th, and 8th grade students not engaged in double dosing? Double dosing means pulling struggling students from elective classes during the school day in favor of an extra remediation class generally in the areas of reading, writing and math. The practice of double dosing is more prevalent within the elementary schools; however, as a result of the high stakes brought about through No Child Left Behind (NCLB), the practice is gaining popularity at the secondary level. The literature supports instructional time being positively correlated with student achievement; however, the literature is limited and dated regarding double dosing and remediation as sources for this increase in time. An independent samples t-test was utilized to compare existing data in the form of grades and standardized test scores between a total sample (N=109) of below benchmark middle school students who were and were not double dosed. Statistically significant results were found between the dependent variable of standardized test scores and the independent variables: math lab (M=60.48) and no math lab (M=51.93), t=-1.848, p=. 004. Likewise, statistically significant results were found between the dependent variable of grades and independent variables: math lab (M=3.77) and no math lab (M=3.27), t=2.449, p=. 0001. The findings provide evidence that there is a significant difference in middle school math achievement between students who are and who are not double dosed. This study may be used to inform K-12 school districts, policy makers, school reform, as well as future research

Horretarako, metodologia parte-hartzailea, aktiboa eta malgua erabili zen. Emaitzek agerian uzten dute belaunaldien arteko programak aldaketarako bide gisa eraginkorrak direla, eta adin guztietarako jendartearen aldeko apustua egiten duten gizarte esku-hartzeak behar direla

Project C.O.R.E.: Coaching Opportunities with Real Experiences

Retention and graduation rates of VCU men of color (MOC) is significantly lower than white men and women of color. Due to demonstrated significant attrition occurring after the sophomore year, Project C.O.R.E. (Coaching Opportunities with Real Experiences) is proposed as a sophomore-focused program that builds upon an existing freshman course on professional development for MOC. While the first-year course introduces students to a VCU support network, Project C.O.R.E. aims to increase university retention by expanding the student support network to members of the local community. Students are paired with community coaches, predominantly VCU alumni, to enhance their career and life-skills development. This program provides continued community, guidance, and support to encourage MOC to continue on the path to graduation

Sloshing reduced-order model trained with Smoothed Particle Hydrodynamics simulations

The main goal of this paper is to provide a Reduced Order Model (ROM) able to predict the liquid induced dissipation of the violent and vertical sloshing problem for a wide range of liquid viscosities, surface tensions and tank filling levels. For that purpose, the Delta Smoothed Particle Hydrodynamics (δ-SPH) formulation is used to build a database of simulation cases where the physical parameters of the liquid are varied. For each simulation case, a bouncing ball-based equivalent mechanical model is identified to emulate sloshing dynamics. Then, an interpolating hypersurface-based ROM is defined to establish a mapping between the considered physical parameters of the liquid and the identified ball models. The resulting hypersurface effectively estimates the bouncing ball design parameters while considering various types of liquids, producing results consistent with SPH test simulations. Additionally, it is observed that the estimated bouncing ball model not only matches the liquid induced dissipation but also follows the liquid center of mass and presents the same sloshing force and phase-shift trends when varying the tank filling level. These findings provide compelling evidence that the identified ROM is a practical tool for accurately predicting critical aspects of the vertical sloshing problem while requiring minimal computational resources

Wh-Islands in L2 Spanish and L2 English: Between Poverty of the Stimulus and Data Assessment

This paper sheds light on the acquisition of wh-islands in L2 English spoken by native speakers of Spanish and L2 Spanish spoken by native speakers of English as well as on the distribution of wh-islands in L1 Spanish. A grammaticality judgment task with a 7-point Likert scale provides evidence that wh-island effects are present in L1 and L2 Spanish as well as L1 and L2 English. The L1 Spanish facts challenge the received view of wh-islands in this language, in keeping with recent developments which show that islands are more widely attested across languages than previously thought. These facts also highlight the dialogue between L2 research and replication studies thanks to the use of native control groups

An Approach to Quantify Workload in a System of Agents

The role of humans in aviation and other domains continues to shift from manual control to automation monitoring. Studies have found that humans are often poorly suited for monitoring roles, and workload can easily spike in off-nominal situations. Current workload measurement tools, like NASA TLX, use human operators to assess their own workload after using a prototype system. Such measures are used late in the design process and can result in ex- pensive alterations when problems are discovered. Our goal in this work is to provide a quantitative workload measure for use early in the design process. We leverage research in human cognition to de ne metrics that can measure workload on belief-desire-intentions based multi-agent systems. These measures can alert designers to potential workload issues early in design. We demonstrate the utility of our approach by characterizing quantitative differences in the workload for a single pilot operations model compared to a traditional two pilot model

Analysis of the Damage Evolution in Steel Specimens under Tension by Means of XRCT

When a steel specimen is tested under tension, damage usually develops evenly all along the specimen, finally necking and leading to the typical cup-cone fracture surface. Nevertheless, some steels present an unusual fracture pattern consisting on a plane fracture surface with a dark region in the centre of the fracture zone. In this contribution, the authors analyse the evolution of the internal damage by using X-ray computed tomography (XRCT) on 3mm-diametre specimens of two steels. The specimens are tested in subsequent loading steps, after each of which it is unloaded and analysed with XRCT. This procedure helps to identify the evolution of damage developed inside each specimen at predefined strain levels. XRCT reveals a very high initial porosity in the material with the cup-cone fracture pattern and a very low initial porosity in the other. In the latter, fracture is triggered by a concentrated internal damage that can be seen as an internal notch which produces a stress concentration that leads to the eventual failure

Crowdsourcing synchronous spectator support:(go on, go on, you're the best)n-1

Many studies have shown that crowd-support, such as cheering during sport events, can have a positive impact on athletes’ performance. However, up until recently this support was only possible if the supporters and the athletes were geographically co-located. Can cheering be done remotely and would this be effective? In this paper we investigate the effect and possibilities of live remote cheering on co-located athletes and online supporting crowds that have a weak social tie and no social tie with the athlete. We recruit 140 online spectators and 5 athletes for an ad-hoc 5km road race. Results indicate that crowds socially closer to the athletes are significantly more engaged in the support. The athletes were excited by live remote cheering from friendsourced spectators and cheering from unknown crowdsourced participants indicating that remote friends and outsourced spectators could be an important source of support
