IMPACT OF ACTIVE LEARNING STRATEGIES TO ENHANCE STUDENT PERFORMANCE

This study is an attempt to discuss the impact of active learning strategies to enhance student performance. Education is an integral part of every human being. It moulds him to be a good citizen, who is really an asset of the country. The wealth of a nation depends on the education of its citizensâ€. Teachers have a noble role in imparting knowledge to the innumerable members in a society. Ever wonder why students pay their tuition and fees, purchase expensive textbooks, rearrange their work schedules and personal lives to enroll in classes, attend classes for short or long periods of time and then suddenly drop the class or simply stop attending? This perplexing question probably has festered in the minds of many college professors those of us who are committed to imparting wisdom, knowledge, and understanding to help shape the minds of our students. Certainly a multitude of reasons could account for the sudden disappearance of our students, who seemingly are plucked away one at a time.  The school teachers, to capture the minds, evoke the interest, and enhance the motivation of those students; obviously there are many answers to this timeless question.  One answer, however, lies in the content of this paper employing active learning strategies in the classroom

Radiation and non-​Darcy effects on convection in porous media

Combined conduction , convection and radiation heat transfer in a gray fluid-​satd. sparsely packed porous medium is analyzed for the case of marginal convection by using linear stability anal. The effects of boundaries and inertia that are absent in the usual Darcy model are considered. The Milne-​Eddington approxn. is employed to det. the solns. valid for transparent and opaque media that absorb and emit thermal radiation. The nature of the bounding surfaces and radiation affect the crit. Rayleigh and wave nos. The mechanism for suppressing or augmenting convection is discussed. The results obtained by using the Galerkin technique are compared with the existing results of the Darcy model and of nonradiating systems, and agreement is found

An Overview Study on Awareness of Global Warming Among the Graduate Teacher Trainees

Nowadays global warming is considered as a burning problem and it is being a challenge to the entire world and its scientific society. Global warming is a worldwide environmental problem by which there is an abnormal increase to the level of temperature, particularly in a natural environment. Global warming is not only affecting the nature, but it affects the life and homes of millions of people. The changes of global warming is visible from the highest mountains to deep in the oceans and it extinguished different parts of the earth and it's also creates rich bio-diversity. To identify the level of awareness global warming and to enhance the same among future secondary school teachers, the Authors decided to conduct the present research study of awareness on global warming among graduate Teacher trainees of college of education. Further, the study may also help the student teachers of secondary schools to create awareness on global warming among students studying in secondary schools in future. Keywords: global warming, climatic Change, green house effect, environmental refugees, and 3R

Effect of radiative transfer on the onset of convection in a porous medium

The effect of radiative transfer on thermal convection of a thin fluid-saturated densely packed porous layer bounded by stress-free radiating horizontal planes heated from below is studied using linear theory. The coefficients of absorption, emission and scattering are computed from packed bed properties using a two-flux model. The Milne-Eddington approximation is employed to determine approximate solutions valid for optically thin (transparent) and optically thick (opaque) gray media which absorb and emit thermal radiation. The effect of radiation parameters on the cell size and on the onset of convection are studied in detail using the Galerkin approximation. It is shown that the effect of radiation is to inhibit the onset of convection in a porous medium. The physical explanation for this is given, taking into account the increase in thermal conductivity due to the combined effects of the porosity of the medium and radiation

Effect of Information Processing Approach in Enhancing Achievement in Chemistry at Higher Secondary level

Teaching is considered both an art and a science.  Successful and effective teaching requires two basic things.  The teacher should be competent to teach the subject allotted to him/her at the same time he/she should follow new techniques of teaching to make the learning fruitful and interesting. The traditional methods of technology have failed to generate the required behavioural outcomes, abilities and skills needed to facilitate the learning of curricular subjects. Knowledge of the recent development will help the teacher in making his/her teaching more effective and increase his/her efficiency for class room functioning.  Such a background will solve classroom problems, enable him/her to organize teaching activities and select instructional design and teaching models and innovative techniques appropriate for his/her classroom situation.  All innovative strategies and techniques, it should give enough scope for developing learning environment among students. Processing information is the main concern of any teacher.  If the information is processed effectively, learning techniques should be right and they should meet the individual needs of all learners and so the teachers should adopt a model of teaching which would be flexible and interactive.  The information processing approach technique in teaching chemistry was effective in Higher Secondary School classes. Implementation of this approach provided a great opportunity, to students to take an active part in the process of learning.  Through the information processing approach the achievement of student was enhanced to a great extent.Keywords: Information, Processing, Model, Chemistry

A Study of Pattern of Secretion of Melatonin in Saliva and Sleep Parameters in Shift Workers

BACK GROUND: Globalization and industrialization has lead the shift workers vulnerable for circadian rhythm sleep disorders. AIM AND OBJECTIVE: To know how far the sleep parameters secretory pattern of melatonin levels in saliva are deviated in shift workers from that of the day workers. MATERIALS AND METHOD: The study included 30 age matched male shift workers (mean [SD] age: 21.33 [0.48] years) and 30 healthy day workers (mean [SD] age: 24.97 [2.55] years). Polysomnography was performed along with self rated subjective sleep scoring questionnaires. Three Saliva samples for the measurement of melatonin were collected from participants resting in dim light at 2 hr min intervals between 20:00 and 00:00 hr. RESULT: Total sleep time, Sleep Efficiency, and duration of rapid-eye-movement sleep showed a significant reduction while Slow-wave sleep (stages 3+4) doesn’t show a significant reduction in shift workers as compared with day workers. A significant decrease in time line trend of salivary secretion of melatonin was observed in shift workers. Subjective sleep scores were significantly more towards inadequate sleep for shift workers. CONCLUSION: The circadian phase is altered in shift workers as compared to day workers proved using salivary melatonin concentration as a marker of the same. This study showed shift workers are more prone for sleep disorders, affecting one’s health and productivity in society. Early diagnosis, behavioral and life style modification, health education and medication, may alleviate such problems

Emerging small scale trap fishery for whelk, (Babylonia spirata) in Malpe, Southern Karnataka

Babylonia spirata is a commercially important edible gastropod found inhabiting the coastal waters with sandy bottom. Commonly known as whelks, they are landed as by-catch in shrimp trawlers in Kerala and Tamilnadu.There is an emerging fishery for whelks along the Malpe coast (13° 21’ N and 74°42’5” E) with the increase in export demand. Specially designed whelk traps are operated from traditional fishing crafts to collect whelks since January 2005

Variability in open pollinated seedlings of black pepper (Piper nigrum L.)

Highly heterogeneous variances were observed for plant height, leaf number, leaf width, internode len gth and stem girth in open pollinated seedlings of three black pepper (Piper nigrum) cultivars. Collection 1344 had maximum range and coeffici ent of variation for all the characters followed by Panniyur-1 and a Karimunda Selection KS-27. Eighteen di stinct morphological variants were also recorded in the progeny of Coll. 1344. In some of the progenies, the initial variation sustained wi th growth for most of the morphological features. No such morphological variants were observed in the progenies ofPanniyur-1 and KS-27. The reason for this behaviour of the cultivar is di scussed. &nbsp
