A University-Based Literacy Service-Learning Program for Youthful Offenders on Probation: A Preliminary Study of the Program’s Development,Implementation and Feasibility

This article reports on the development, implementation and feasibility of a mid-Atlantic university-community service-learning literacy program for youth on probation. Undergraduate teacher candidates served as literacy instructors for the youth. We focus on benefits and administrative challenges of developing and implementing a preliminary service-learning program for probated youth living in the community. We analyzed focus group data collected from special education undergraduate instructors, interview data collected from probated youth and their case managers, pre-post literacy assessments administered to the youth, the youths’ court files and data maintained by the community-based agency. We conclude that our model of a university-community literacy partnership has the potential to raise reading performance of youth, motivation, and promote prosocial behaviors. Addressing the educational needs of youth on probation, however, is complex and multifaceted. We find that success requires consistent communication among all stakeholders, adequate funding for leadership, organization and curricula, and ongoing assessment and evaluation.     

Indian Astronomy: the missing link in Eurocentric history of Astronomy

A comprehensive history of Astronomy should show in reasonable chronological order, the contributions from wherever they arise in the world, once they are reliably documented. However, the authors note that consistently, the extremely rich contributions from Ancient Indian scholars like Aryabatha and Bhramagupta are omitted in Eurocentric education and syllabi. It is speculated whether religious underpinnings could have been responsible for its suppression in the past. An appeal is made to represent the history of Astronomy in Eurocentric versions, to be inclusive of Indian Astronomy as accurately and completely as possible in science education.     

The use of clickers in Instrumentation and Control Engineering education: a case study

ABSTRACT

This paper presents results from a small-scale study of third-year Instrumentation and Control Engineering (n?=?37) at the University of Plymouth. The aim of the study was to enhance student learning and increase participation via the use of clickers. Clickers allow for student participation anonymously. The lecture content was modified to embed clicker questions at regular intervals to test knowledge, understanding and cognitive skills. Largely, the students preferred interactive lectures to traditional didactic lectures and using clickers increased student engagement and participation. Interestingly, compared to assessment results from the previous year, the increased level of engagement did seem to lead to an overall improvement in grades of approximately 10% in the subject of Control Engineering. However, in Instrumentation, the average fell by approximately 20%. One possible contributory factor of this drop could be the changed exam format for Instrumentation only. This year, the multiple choice section was removed from the Instrumentation examination paper. Furthermore, an analysis of variance showed that in addition to using clickers in the lectures, attendance plays a key role. Results of this small-scale study show that for a more complex subject like Control, student learning, engagement and attainment can increase by the use of clickers.     

Chemical oscillations

The law of mass-action led chemists to the belief that reactions approach equilibrium steadily. So the discovery of chemical oscillations came as a surprise. Now chemists are very familiar with reactions that oscillate in time and/or space. Experimental and theoretical studies of such reactions showing temporal and spatial oscillations attract the interest of many laboratories world-wide. The Lotka-Volterra model is the simplest mathematical model which exhibits such oscillations. In this article, we use this model to illustrate chemical oscillations with the help of a computer program.     

Struggling toward a transformative model of instruction: It's not so easy!

This article is about the moving toward a new instruction style—a transformative model of instruction. One university instructor attempts to change her teaching strategies, and she encounters her own belief as obstacles, self-labeled her pedagogical discrepancies. Through peer feedback, reflective journal writing, and readings she uncovers the obstacles and discovers how the beliefs need to change in order to implement transformative teaching strategies. The change is incorporated into five lessons: it is easier to tell than to listen; modeling needs to go beyond a monologue; be humble and learn from the students; there are more ways to the same end; and, grading the end product or acknowledging the risk. Her lessons take on a spiral nature of learning, and incorporate detailed emotional–psychological resistance. In doing so, she gains a deeper understanding of her instruction, and becomes better equipped to prepare other reflective practitioners. The study takes place in the continental United States of America.     

Combined Analysis of Anti SARS-CoV-2 IgG and IgM Responses in COVID19 Patients in India

Coronavirus disease 2019 (COVID-19) caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a global health problem, India being the second most affected country. The kinetics of antibody response to SARS-CoV-2 in Indian population is not studied yet. To understand serological response in relation to age, gender, time period and severity of disease, Roche Elecsys anti-SARS-CoV-2 test was used which analysed both IgM and IgG. One hundred and three COVID-19 patients were enrolled. Seropositivity was seen in 64% of patients, with 33% at ≤ 7 days, 62% between 8 and 15 days and 81% at ≥ 16 days from the time of admission. Men (65%) showed higher antibody response than women (59%), whereas no difference was observed in seropositivity with respect to age of the patients. Dynamics of antibody responses revealed individual variations. Patients in ICU had higher antibody reactivity with 67% positivity as compared to 60% positivity in non-ICU patients. Kinetics of antibody response during COVID-19 disease varied in relation to gender, age, time period and severity and these factors might play an important role in treatment and control of COVID-19.     

An easy, rapid and cost-effective method of microtitration

An economical and less time consuming microtitration method is presented. The method has been applied to two types of titration, viz., neutralization and complexometric. The results obtained by the new method are comparable to those obtained by conventional method using burette and pipette. It is proposed that this method can be implemented in high school and undergraduate classes as the quantities of chemicals consumed are far less and the experiment can be completed within the given laboratory period.
