Relacionamento conjugal, problemas de comportamento e habilidades sociais de pré-escolares

Variáveis do relacionamento conjugal e relacionamento pais-filhos podem afetar o comportamento das crianças. O objetivo deste trabalho é comparar relatos de pais e mães de pré-escolares com e sem problemas de comportamento, quanto ao relacionamento conjugal. Participaram 48 casais, distribuídos em dois grupos: pais biológicos de crianças com problemas de comportamento e pais biológicos de crianças socialmente habilidosas, segundo avaliação de professores. Os pais foram entrevistados, individualmente, sobre expressão de carinho, comunicação conjugal, características positivas e negativas do cônjuge e qualidade do relacionamento conjugal. Foram encontrados alguns resultados na direção esperada. Os casais com criança socialmente habilidosa foram mais positivos quanto à comunicação e características do cônjuge. Não foram encontradas diferenças na expressão de carinho.

Associação entre posicionamento do aluno na sala de aula e desempenho escolar

This research was aimed at analyzing whether there is an association between the positioning of the pupil in the classroom and his academic performance, as well as to diagnose the main factors underlying the association. Thus, this study analyzed 4 Elementary School II institutions of both public and private educational systems, in Botucatu, São Paulo, Brazil during a school year bimester. To register the positions students were seated, 29 similar classes (containing 6 rows x 6 columns) were investigated, each one with around 30 students, which resulted in a sampling of 859 students. For the questionnaire application, which objective was to verify the main reason for students’ seat choice, the same 29 classes were investigated. However, the sampling number was reduced to 692 students. In turn, for the collection of school performance and absence percentage of each student for the bimester in question, teachers’ evaluation books were used. As a result, it was found that the lower the percentage of the student's absences, the greater is their performance at school, and the greater their performance at school is, the closer up front to the board they are seated. Finally, the closer up to the board they are seated, the more their motivation and interest in learning increase. Therefore, there is an association between the position of a student in the classroom and his or her academic performance, where the association is conditioned by the motivation and interest in learning

Vocal evaluation in teachers with or without symptoms

The aim of this study was to perform voice evaluation in teachers with and without vocal symptoms, identifying etiologic factors of dysphonia, voice symptoms, vocal qualities, and laryngeal lesions. Eighty teachers were divided into two groups: GI (without or sporadic symptoms, 40) and GII (with frequent vocal symptoms, 40). They answered a specific questionnaire, and were subject to a perceptual vocal assessment (maximum phonation time, glottal attack, resonance, coordination of breathing and voicing, pitch, and loudness), GIRBAS scale, and to videolaryngoscopy. Females were predominant in both groups, and the age range was from 36 to 50 years. Elementary teachers predominated, working in classes with 31-40 students. Voice symptoms and alterations in the perceptual vocal analysis and in the GIRBAS scale were more frequent in GII In 46 teachers (GI-16; GII-30), videolaryngoscopy exams were abnormal with the vocal nodules being the most frequent lesions. These results indicate that a teacher's voice is compromised, and requires more attention including control of environmental factors and associated diseases, preventive vocal hygiene, periodic laryngeal examinations, and access to adequate specialist treatment.

Evaluation of toothbrush bristles' deterioration used by preschool children

The toothbrush is an effective instrument for oral diseases prevention. The flexibility and status of bristles, as well as the size of the handle are fundamental for an effective toothbrushing. Thus, the assessment of physical characteristics of toothbrushes is important. This study evaluated the deterioration and wear of bristles of toothbrushes used by preschool children. For the sample selection, five elementary schools were assorted from a city of the São Paulo State northwest region, one from each city area. All toothbrushes used by preschool children who aged between 5 and 6 years old and who attended the assorted schools were visually analysed by two calibrated examiners, according to the criteria proposed by Rawls HR, Mkwayi-Tulloch NJ, Casella R, Cosgrove R (J Dent Res 1989; 12: 1781): 0 - it is impossible to state if the toothbrush was used or not; 1 - the bristles seem to be separated within some tufts; 2 - most tufts are separated, many cover other tufts and present a large number of curved and inclined bristles; 3 - most tufts are covered by others and bristles are folded and tipped. In total, 333 toothbrushes were evaluated. The data obtained revealed that 57.96% of the toothbrushes presented adequate condition for utilization (scores 0 and 1), whereas 42.04% presented inadequate bristles for their function (scores 2 and 3). It was concluded that a great number of toothbrushes presented deterioration of the bristles. Thus, there is the need to guide and promote awareness among teachers, parents and children as well as the need to replace toothbrushes.

Voice disorders in teachers: clinical, videolaryngoscopical, and vocal aspects

Dysphonia is more prevalent in teachers than among the general population. The objective of this study was to analyze clinical, vocal, and videolaryngoscopical aspects in dysphonic teachers. Ninety dysphonic teachers were inquired about their voice, comorbidities, and work conditions. They underwent vocal auditory-perceptual evaluation (maximum phonation time and GRBASI scale), acoustic voice analysis, and videolaryngoscopy. The results were compared with a control group consisting of 90 dysphonic nonteachers, of similar gender and ages, and with professional activities excluding teaching and singing. In both groups, there were 85 women and five men (age range 31-50 years). In the controls, the majority of subjects worked in domestic activities, whereas the majority of teachers worked in primary (42.8%) and secondary school (37.7%). Teachers and controls reported, respectively: vocal abuse (76.7%; 37.8%), weekly hours of work between 21 and 40 years (72.2%; 80%), under 10 years of practice (36%; 23%), absenteeism (23%; 0%), sinonasal (66%; 20%) and gastroesophageal symptoms (44%; 22%), hoarseness (82%; 78%), throat clearing (70%; 62%), and phonatory effort (72%; 52%). In both groups, there were decreased values of maximum phonation time, impairment of the G parameter in the GRBASI scale (82%), decrease of F0 and increase of the rest of acoustic parameters. Nodules and laryngopharyngeal reflux were predominant in teachers; laryngopharyngeal reflux, polyps, and sulcus vocalis predominated in the controls. Vocal symptoms, comorbidities, and absenteeism were predominant among teachers. The vocal analyses were similar in both groups. Nodules and laryngopharyngeal reflux were predominant among teachers, whereas polyps, laryngopharyngeal reflux, and sulcus were predominant among controls.

Evaluation of the relationship between education and sustainability in peasant movements: The experience of the National Education Program in Agrarian Reform

Brazil is one of the largest agricultural producers in the world. However, its agrarian composition is based on two markedly different production models, particularly in relation to sustainability: a peasant family agriculture, which plays an important role in food production for domestic consumption and advocates agro-ecological practises; and agribusiness, the politically and economically hegemonic model that produces commodities for export based on monoculture and intensive use of pesticides. Therefore, in order to create the means to develop peasant lands, social movements and peasants have engaged themselves politically and defended an education model grounded in sustainable practises of production and social organisation. Taking this into account, the main purpose of this paper is to analyse and assess the Brazilian experience of integration between education and sustainability, in the National Education Program in Agrarian Reform (PRONERA). To accomplish this aim, a survey with a semi-structured questionnaire was carried out among teachers, students, monitors, and coordinators of the course offered by PRONERA. The surveys showed that the courses are promoting the concepts of sustainability among peasants. However, many adjustments need to be taken into consideration during the planning process for the next courses offered by PRONERA.

Physics teachers initial education and professional performance: what do future teachers have to say?

This research deals with the discussion about Physics teachers’ undergraduate education and professional performance related to the knowledge acquired during this initial education. More specifically, we try to answer questions like: How do future teachers evaluate the knowledge acquired during their initial education as in terms of specific knowledge as pedagogical knowledge? What are their formative needs and future expectatives about professional performance and the school teaching environment? Data was constituted from a sample of 26 future high school physics teachers, one semester long, that were taking the supervised curricular training in a undergraduate Physics education program (called Licenciatura in Brazil), in São Paulo State public university. Besides the final report of this training, future teachers were asked to answer a questionnaire aiming to take their conceptions about their initial education program, their formative needs, future professional expectatives and high school teaching environment. According to the future teachers, the program they were about to finish was satisfactory in terms of Physics specific contents; however, about the pedagogical content knowledge and the pedagogical practice, they showed to be unsatisfied and insecure. The majority of the questionnaire responses demonstrated that they feel lack of teaching experience. Moreover, teachers emphasize other factors related to the future professional performance: possible difficulties to deal with students’ indiscipline, schools’ bad physical structure, limited number of Physics classes in high school level, lack of didactical laboratories and also they seem to be frightened that the expertise teachers do not be collaborative with the new ones. In this sense, the research outcomes shows the necessity of discussions about questions involving teachers knowledge, related to either, the Physics conceptual domain and the pedagogical one, since it matters directly to future teachers professional performance. Discussions in this sense can also help evaluation and restructuration of programs designed to initial and continuous teachers’ education.
