Two Age Groups

This study investigated how learners’ ages affect their interpretation of the nonverbal behaviors (NVBs) of teachers and other students in distinguishing between questions and statements in the second language (L2) classroom. After watching 48 short video clips without sound in which three L2 teachers asked a question or made a statement with or without gesture, 36 elementary school pupils and 30 university students judged whether they thought the teachers asked a question or made a statement along with their reasons. The findings show that, regardless of learners’ ages, L2 teacher’s gestures were found to help learners better identify questions. Furthermore, the six major types of NVBs used for judgments most frequently were identical across the two age groups regardless of the accuracy of their judgments. Nevertheless, incorrect judgments were made as often and sometimes even more often than correct judgments by applying the same assumptions. The effect of age was evidenced in that the university students were able to use a larger number of NVBs for correct judgments, and better distinguish questions and statements without linguistic information than the elementary school pupils. The data suggest that it is the learners’ (L2) classroom experience that seems to be playing the major role in yielding this difference. The study indicates that adult L2 learners are better able than children to incorporate and interpret NVBs of teachers as well as other students quantitatively and qualitatively.

This paper describes a collaborative research and development project between the University of Applied Sciences Northwestern Switzerland and Rhodes University in South Africa. The project seeks to establish, disseminate and research the efficacy and use of short video clips designed specifically for the autonomous learning of mathematics. Specific to the South African context is our interest in capitalising on the ubiquity of cellphone technology and the autonomous affordances offered by mobile learning. This paper engages with a number of theoretical and pedagogical issues relating to the design, production and use of these video clips. Although the focus is specific to the contexts of South Africa and Switzerland, the discussion is of broad applicability.

ResumoNeste artigo analisamos as relações com o saber, com o ensinar e com o aprender em atividades desenvolvidas em um subprojeto de Matemática no Programa Institucional de Bolsas de Iniciação à Docência (PIBID). Os dados consistiram no registro das ações realizadas em sala de aula por um supervisor (professor), seis estudantes da licenciatura em Matemática e alunos do Ensino Fundamental de uma escola pública do estado do Paraná, Brasil. Para a interpretação dos dados foi utilizado um instrumento que possibilita evidenciar as relações com o saber na sala de aula denominado Matriz 3x3. As análises revelaram implicações da ação do supervisor na ação tanto dos estudantes universitários quanto dos alunos da escola e, consequentemente, nas relações que estes estabeleceram com o saber, o ensinar e o aprender.AbstractIn this article we analyze the relationship with knowledge, with teaching and with learning in activities developed in a subproject of Mathematics in the Institutional Program of Initiation to Teaching (PIBID). The data consisted of the registration of actions carried out in the classroom by a supervisor (teacher), six undergraduate students in Mathematics and students of the Elementary School of a public school in the state of Paraná, Brazil. For the interpretation of the data we used an analytical instrument called Matrix 3x3. The analyses revealed the implications of the supervisor's action on the actions of the university students and of the school students and consequently on the relationships they established with knowledge, teaching and learning.

The Relationship

Background: Vitamin D deficiency is today acknowledged as a pandemic. Vitamin D deficiency and insufficiency are associated with many chronic diseases, including common cancers, cardiovascular diseases, metabolic syndrome, and infectious and autoimmune diseases.Objective: This study aims to investigate the relationship between the cotinine level in urine and Vitamin D.Methods: This study employed a descriptive and relational screening design.  It was conducted with 74 smoking university students between January 2019 and March 2020. Data were collected through socio-demographic form and Fagerstrom test for nicotine dependence. Besides, the participating students’ blood and urine samples were taken in a suitable environment.Results: The average age of the participating students was 21.50±2.09. Of all the students, 71.6% were males, 62.2% were exposed to the sun between 12 p.m. and 2 p.m., and the average number of cigarettes smoked daily was 13.52±8.22. The average Vitamin D level in blood was 32.4±15.3 (ng/mL), and the average cotinine level in urine was 1.60 ± .32 (ng/L). No statistically significant relationships were found between the Vitamin D level and the cotinine level (p<0.05).Conclusion: Smoking causes diseases and death in many people, and it is a changeable risk factor.  Nursing practices on the struggle against smoking are effective. No significant relationships were found between the Vitamin D level in blood and cotinine level in urine. Similar studies are recommended to be conducted with larger groups and participants from different age groups.

The aim of this study was to estimate the prevalence of insomnia, differences between males and females, and between two age groups, and to explore the factorial structure of the Arabic Scale of Insomnia (ASI). Samples of university students (n=500) and employees (n=457) of both sexes were recruited. Female university students obtained the highest mean total score on the ASI, followed by female employees, male university students, and finally male employees. The salient significant differences were between female students and male employees and between male and female employees. Despite the differences in the prevalence rate of insomnia between the four groups, they all agreed on that the least prevalence rate was for the item: “I feel depressed when it is time for me to go to bed, whereas the highest prevalence rate was for the item: “My interrupted sleep annoys me.” Principle components analysis yielded three factors for each group. Most of their names were not identical. The most salient finding of this study was the statistically significant sex differences in insomnia in favor of women. It was concluded that is it important to introduce counseling for those who obtained high scores on the ASI.

Abstract Aims and Objectives: To assess the posed and dynamic smile and to compare the various attributes of smile in frontal, oblique and sagittal dimensions, in two different age groups (10- 15years and 18-25 years). Materials and Methods: The posed and dynamic smile parameters were measured using digital video clips in 80 subjects of two different age groups (10-15years and 18-25 years). Total of 15 parameters were studied in 3 planes of space. The data was analysed using student`s t-test to compare smile parameters across the age groups, paired t-test was used to analyse the parameters of posed and unposed smile within the same age group and chi-square test was performed for the discrete data. Results: The present study revealed significant differences in dynamic smile parameters between the two age groups. The parameters like Philtrum height and Smile index are more in older age group whereas the buccal corridor was more in younger age group. Significant differences were also recorded in various parameters in both the groups when the posted smile is compared with that of the dynamic smile. Conclusion: In both the age groups, the dynamic and posed smile attributes are significantly different, except for buccal corridor and interlabial gap.

The purpose of this study was to describe the effect of age on specific psychological and behavioral measures of learned-helpless and mastery-oriented students. The study consisted of two age groups, younger and older, of learned-helplessness and mastery-oriented students. Within each age group, learned-helpless and mastery-oriented students were compared in terms of attributional profiles and levels of task persistence during instruction. Students were asked to view videotapes of their performances, to describe how they thought they did on each task, and to give reasons for their performance. Responses were classified into four attributional categories: (a) ability, (b) effort, (c) task difficulty, and (d) environment or luck. Persistence was also determined by looking at the number of times students would attempt a task. Attributional profiles and task persistence associated with the leamed-helpless condition was more prevalent with the older group than with the younger group.

For the past few years, we have been experimenting with an e-learning approach to our introductory laboratory classes for first year students. Our overall objective was to maximise students’ useful time in the laboratory. We considered that time spent with students gathered around a desk watching a demonstration is not an efficient use of staff or students’ time.It is well recognised that students’ performance in the laboratory can be enhanced if they are familiar with the background of the experiments which will be conducted, hence the use of ‘pre-labs’. We have been delivering our ‘pre-labs’ electronically by requiring students to work through a package before coming to the laboratory. As well as covering the theory and background to the experiment, short video clips have been included so that students will also have seen the experiment being performed. They should at least recognise the apparatus! The package concludes with a short assessment quiz which must be completed.The packages were mounted on the University network using WebCT and meant that students could undertake the exercises at a time (and place) of their choosing rather than being confined to set laboratory hours.This communication will describe the packages and our experiences as well as an initial evaluation of our approach. Although largely anecdotal, staff felt that they spent less time on more mundane aspects of laboratory work and more time discussing chemistry.Students also felt that they were better prepared for the experiments before they came to the laboratory. Some of the pitfalls and technical problems that had to be overcome willalso be described.

The goal of the study was to examine the effect of age and sex on the quality of wild boar offal and meat. A number of 32 hunt-harvested animals was assigned to groups according to age (juveniles and sub-adults) and sex. The quality of offal (liver, kidneys, heart and tongue) and m. semimembranosus was examined. The pH value of m. semimembranosus ranged from 5.45 to 5.88. The highest pH was recorded in the kidney and the liver (6.32–6.54 and 6.12–6.31). The meat in the group of juveniles was brighter (p = 0.042), yellower (p = 0.039), showed a greater drip loss (p = 0.007), cooking loss (p = 0.039), and plasticity (p = 0.028), compared to the sub-adults. The extractable fat content in the m. semimembranosus and offal (p = 0.004), and water to crude protein ratio (p = 0.033), also differed between age groups. The results of the study show different quality attributes of offal and meat of wild boars from two age groups. The obtained quality measures suggest that the culinary and technological usefulness of offal and meat from the wild boars may differ according to the age of hunted animals.

A Performance

The effect of age, sex, speed, and practice on coincidence-anticipation (C/A) performance of elementary school children was investigated. 84 elementary school children, 7 boys and 7 girls at Ages 7, 8, 9, 10, 11, and 12 yr., served as subjects for the study. Subjects were given 24 C/A trials, 6 each at 4 speeds, randomly presented. Subjects were required to lift the foot off a spring switch in coincidence with the arrival of a ball at a target flag. A score was determined as the difference between actual time and the estimate as recorded on separate .01-sec. Lafayette timers. The data were analyzed employing a 6 by 2 by 4 by 3 factorial design. Results indicated that 7-yr.-olds performance was inferior to those of all other age groups, boys were more accurate than girls, and all groups exhibited improvement over practice.
