A survey of teachers\u27 perceptions of homogeneous, heterogeneous, and multiage grouping and the achievement results of their students
Get PDFMany schools in the state of Louisiana are being rated as either effective or at-risk. The public looks down on those schools that are at-risk and hold a corrective action status. If the schools in corrective action do not improve over a three-year period, they will be closed forever. Now faced with possibility of losing their jobs, teachers need to discover the most effective techniques and strategies of teaching students more than ever before. These have been studies, which indicate that grouping students for instruction id productive and effective. But which grouping method is best? There are many different grouping methods such as homogeneous or ability groupings, heterogeneous, multiage grouping. The professional literature has put forth some conflicting information. This study will focus on teachers\u27 perceptions about the grouping methods they use in their classrooms and the effect it has on the students\u27 overall success in test taking. This study attempts to answer several fundamental questions regarding grouping students. Is there a relationship between teachers\u27 perceptions toward homogeneous, heterogeneous, and multiage grouping and the effectiveness of the instruction when delivered by different grouping methods? Secondly, is there a relationship between homogeneous, heterogeneous, and multiage grouping and the students\u27 performance and standardized tests? One final question will be answered in this study: Is a particular type of grouping more beneficial for the student socially and academically? An examination of the evaluation of the data and research literature will assist the researcher in proving that teachers choose to use homogeneous grouping in the core subjects of reading and mathematics whereas heterogeneous grouping is used in other academic areas researcher will also prove teachers use heterogeneous grouping to counterbalance some of the disadvantages of using homogeneous grouping, such as poor self-esteem of low ability students
Low temperature (2K - 20K) heat capacity determination of a polycrystalline zirconium oxide (ZrO) based material containing calcium (Ca) and europium (Eu)
Get PDFThe calorimetric properties of a CaEuZrO based sample, synthesized by a solid-state reaction process in the Electron Transport and Magnetic Properties of Materials (ETMPM) lab, are investigated by analyzing low temperature (2 -20 K) heat capacity data. The total heat capacity of a material may be expressed as C = Celec + Cph + Cnuc + Cmag + Ci. In mathematical terms, it may be expressed as C = yT + aT3 + An T-2 + Ci. In this equation, the term yT is the electronic heat capacity, aT3 is the lattice or phonon heat capacity, AnT-2 is the nuclear heat capacity and Ci represents any other heat capacity contributors that may be present. The various contributors may be identified based on their distinct temperature dependence in different temperature ranges. In the study, previously collected heat capacity data for the sample is analyzed. Estimates for the lattice and electronic coefficients were determined to be a= 1 x 10-6 J/g-K4 and y = 2 x 10-7 J/g-K2, respectively. Thus, the lattice heat capacity is dominant in the temperature range from 2 -20 K
Increasing security in mobile ad hoc networks by incentives to cooperate and secure routing
Get PDFA mobile ad hoc network is a self-organizing network that relies on the cooperation of participating nodes in order to function properly. In this network, mobile users arrive within the common range of a wireless link and collaborate in constructing the network topology in order to facilitate communication. Mobile ad hoc networks do not rely on any fixed, centralized routing infrastructure, so there is no base station to provide connectivity. This must be provided by the participating nodes. Although mobile ad hoc networks are quite beneficial in sparse areas and rescue operations, they have several properties, such as unreliable wireless links, dynamic topologies and membership, and constraints in bandwidth and battery power, that increase their susceptibility to security attacks. This creates several security issues that include collaboration and fairness and confidentiality of location. The new routing protocol extensions presented in this research make it possible to detect and punish selfish behavior; therefore, making it unbeneficial to deter from normal behavior. The presented protocol incorporates an incentive to cooperate in a secure routing protocol. This protocol presents a solution to several security issues in mobile ad hoc networks; however, some issues must still be addressed
An analysis of preparedness and qualifications of historically black colleges and universities\u27 accounting gradautes [!] employed in corporate America
Get PDFHistorically black colleges and universities have been accused of not producing a quality education to accountants entering Corporate America. Attributes corporate recruiters look for in employment candidates include leadership, communication, and technical abilities. There has also been continuous concern if corporations are willingly hiring HBCD graduates because of qualifications or just filling the affirmative action quota. In order to determine the preparation and qualification HBCD\u27s provided their accounting graduates, I designed a survey targeting accounting graduates of predominately black populated institutions currently employed in the corporate world . Fifty-two accountants representing twenty-one corporations and eleven HBCDs participated in the survey that consisted of eleven questions concerning the institution and four questions concerning the corporation. The accountants gave similar opinions regarding the HBCDs preparations, but varied their opinions in the employment qualification. Although HBCDs provide adequate technical skills, communication skills, professor diversity, and business etiquette skil1s, obviously peer diversity is weak at predominately black institutions. Personal competitiveness is comfortable for HBCD accounting graduates. Politics was the only category the accountants expressed their opinions to favor more weakly than very strongly in comparison to salary, job assignments, and promotion intervals
The effect of an African/black psychology class on African American college students\u27 use of the N word
Get PDFThe study investigated whether exposure to an African/Black psychology course (African history, culture, and philosophy) has an effect on 60 African American (40 females, 20 males) at Southern University and A&M College usage of the n word. The n word is defined as nigger or any variation of the word. Past terms associated with it are lazy , no-good , dumb , violent , etc. in reference to persons of African descent. Past research has shown that African American young adults use this word more frequently if they are uneducated of the history of people of African descent. Therefore, the African/Black psychology course is geared toward increasing the level of awareness of African culture. Awareness of African culture is associated with the psychological concept of African self-consciousness, a strong sense of collective African identity which may include a pursuit of self-knowledge, value in African centered institution building, cultural practice, and resistance to Anti-Africaness. Another psychological concept, Cultural Misorientation is a behavior pattern in African people in which they try to think, act and feel like persons of European descent including accepting images, beliefs, and values of this race in America. Prior to the start of instruction, the students completed a battery of Afrocentric assessment measures. The participants matriculated through the course and completed the battery again. The results (post) were compared to the earlier results (pre) from the completed battery. The research resulted in an analysis of variance (ANOV A) of significant difference of p=. 000 for individuals objecting to use of the n word if they had higher ASC levels. An ANOVA also showed significant main effect differences for individuals with low post cm levels p=.017 objecting to the use of the «n\u27\u27 word more than those with high post CM levels

The effects of free and serial recall conditions on the retrival of information from short-term memory
Get PDFThe purpose of the present research was to compare recall of serial lists of verbal materials as a function of the method of learning in terms of free and serial recall. The participants consisted of 166 undergraduate college students ranging in age from 18 - 35 years old. The participants were randomly assigned to conditions of free or serial recall with the restriction that there were an equal number of male and female participants in each condition. The dependent variable recall measured the number of correct responses under each learning condition. The investigator read a list composed of 15 words at a rate of about one word per second to the participants. After the words were read, the investigator allowed the participants 60 seconds for recall. The scores for each recall condition were entered into an independent samples t test. The results of the present research indicated that participants tested under the level of free recall had a higher number of correct responses than, those who were tested under the level of serial recall. With an alpha level set at .05, the independent samples t test results were highly significant, ! (164) = -17.4, Q = .001. While, the mean number of correctly written responses (with standard deviations in parentheses), for those who had free recall and those who had serial recall was 7.05 (1.58) and 2.63 (1.69), in order. It was confirmed that under specific conditions, those participants under free recall had a greater number of correct responses, compared to participants under serial recall

The development and application of a low-cost force feedback system for a haptic interface for use within a three-dimensional virtual reality environment
Get PDFVirtual Reality is a fast growing market. Everyday new applications of this technology are being discovered. Virtual Reality (VR) benefits many sectors of the world market. It has applications in areas such as medicine, research, industry, education, and the military. In the field of medicine, VR is being used to train anesthesiologists in the delicate work of delivering anesthesia and in rehabilitation treatment. Researchers use VR to explore micro- and nanoscale systems with scanning tunneling microscopes. Industrial organizations use VR to operate robotics equipment from remote locations. Educational institutions can use VR to augment course work and in research applications. The military uses VR to train pilots to fly fighter aircrafts and individual so Idier training via simulation. With so many applications emerging, there must be a way to make this technology available to all. VR systems use audio, visual, and haptic interfaces to allow the user to interact with objects in the VR environment. The most difficult component of the VR system is the haptic interface, in that it must provide the user with information on the manipulated object\u27s shape, texture, weight, and any other characteristics that the user may use to identify and object by touch. This study investigates a low cost force feedback system that uses shape memory alloy-driven electric pistons. The pistons were actuated by a set current value and characterized for their behavior. It was found that through quick activation and low current application, the electric piston has the potential to be successfully integrated as a mechanical actuator for a force feedback system
