Assessing Reliability and Validity of Peer and Self-Graded Assessments
No full textThe purpose of this study was to determine the usefulness of peer and self-grades as proxies for the teacher’s grades by evaluating the reliability and validity of evidence-based grading practices in a high school setting. The results of this study were intended to reveal grading strategies, if any, that were useful for teachers in order to bridge the gap between theoretical models of learning and explicit pedagogical techniques. This quantitative correlational study involved one participating teacher from a public suburban high school who administered a written assessment to 77 student participants in an Advanced Placement science course. The students self-graded and peer-graded the assessments using a publicly-released grading rubric from College Board. The researcher employed descriptive and inferential statistics to probe the relationships between peer-grades, self-grades, and teacher grades. The teacher’s grades were highly, positively, and statistically significantly correlated with averaged peer-grades (r(75) = 0.75, p \u3c .001) and self-grades (r(74 )= .66, p \u3c .001). Peer-graders demonstrated good inter-rater reliability (Cronbach’s α = 0.85). Peer-grading accuracy did not statistically significantly improve as students continued to peer-grade. No statistically significant difference in self-grading accuracy was detected when students peer-graded before self-grading. Peer-grades were more acceptable measures of student performance compared with self-grades and can be used as substitutes for teachers’ grades in the limited methodological and demographical context of this study. A larger and more diverse sample of student and teacher participants is recommended for future studies.

Impact of infant’s cranial bones on magnetoencephalography
No full textPresentation Location: Warming House, Olivet Nazarene University
Abstract
Magnetoencephalography (MEG) is practically useful instrument for human neuroimaging research because it is relatively unaffected by the tissue composition and the anatomical structure overlaying human brain. However, this is true only when the human head is assumed a spherically symmetric shape. A structural distortion such as cranial holes may invalidate the assumption, hence deteriorate the accuracy in MEG source reconstruction. This study investigated the influence of the distortion by simulating MEG with infant head models in the early development that feature the formation and closing of anterior fontanel. In overall, the signal difference between the distorted and the intact is approximately \u3c 6% but the extensively depends on the dipole source configuration, thickness and conductivity of cranial bone, and fontanel size. In conclusion, MEG analysis can simplify the brain source reconstruction even with cranial bone distortion but should carefully considered for some instances due to the dependency mentioned above

The juvenile justice system seeks to rehabilitate children, rather than punish them for their criminal behavior. However, the question is raised, has the juvenile justice system failed in its efforts to rehabilitate rather than punish juveniles?
Since the late 1970s, critics of the juvenile courts have sought to abolish this system, arguing that it has failed in its rehabilitation efforts by not punishing serious criminal behavior of juveniles. At the same time defenders of the system contend it is only a minority of juveniles that commit violent offenses and for the majority the system is worthwhile in addressing their problems. Drugs, gangs, and the availability of guns have led to juveniles committing many serious crimes, including murder. This has led critics to Critics assert juvenile courts are no longer adequate in addressing these issues.
Research shows violent subcultures and early childhood trauma caused by abuse and neglect and early exposure to violence greatly increases the risk of behavioral issues in children. Due to this if the criminal justice system were adequately funded, probation and court personnel might be able to provide more intense supervision and rehabilitation efforts. By placing more energy into changing the socioeconomic situation of communities, rehabilitation efforts would improve and crime might decrease
Alcohol Recovery Process Optimization

CSL Behring in Bradley, IL needed help improving their alcohol recovery system. This process allows used alcohol to be reused by the plant. Improvements were made in a virtual simulation software. Suggestions will be used to help the senior engineers at CSL Behring decide what they will do in the future to improve their outdated system.

The Kankakee manufacturing site is a biotech facility that manufactures plasma-based products. Plasma fractionation is a key step in the manufacturing process. Plasma fractionation requires significant quantities of alcohol to be used in the process. At the end of the fractionation process, the alcohol is recovered through the use of a distillation column. It is theorized that the quality of the recovered alcohol impacts the yields of the fractionation process. The goal of the project is to optimize the alcohol recovery process at the Kankakee site
Roman Britain and Anglo-Saxon Britain: Cultural Differences
Get PDFA role of historians is to distinguish between cultural groups. They must investigate the practices and artifacts in order to create a model. This model should accurately explain events such as celebrations, war, or in the case of Britain, cultural intertwining and invasion. Britain is an interesting case to study in the Middle Ages because of the amount of intermixing that takes place. Within the time period of a few hundred years, Britain had seen multiple different distinct people groups inhabit the island. This paper will focus on the major cultural differences of the two earliest invasions, the Romans and Anglo-Saxons, based on militaristic differences, societal differences, and daily life
