En enkätundersökning om lärares syn på hur de arbetar med mål i grundskolan : A survey of teacher´s views on how they work with the goal in elementary school

Detta är en uppsats om lärares syn på målstyrningen vid två skolor samt hur de uppfattar att eleverna uppnår de uppsatta målen. Undersökningen utfördes som en kvalitativ enkätstudie. Resultatet visar att många lärare uppfattar att målen är otydliga vilket resulterar i att de tolkas olika. Angående hur man mäter att eleverna uppnår målen blev resultatet att det finns en mängd olika metoder att tillgå som till exempel loggbok och observation. En tydlig skillnad fanns i svaren bland dem som hade lång arbetslivserfarenhet gentemot den som hade minst arbetslivserfarenhet. Skillnaderna kan bland annat bottna i osäkerhet på sin yrkesroll samt bristande kunskaper i och med kort arbetslivserfarenhet.

School leaders as agents of change : a case study on how two head teachers are trying to implement the learning study method in their school

This paper seeks to describe and discuss the impact of inspections of schools in Sweden. It outlines the political context, based on New Public Management (NPM) theory, according to what role the Schools Inspectorate is supposed to play in order to govern and control. Attention is also devoted, referring an on-going case study, to how inspections influence head teachers and their leadership in their everyday work.   Reports from the Schools inspectorate are public. This forces both politicians and head teachers to take measures. In this case, the head teachers perceived that the inspection reports confirmed what they already knew, but it also gave them an alibi and a tool to push their teachers to take part in everyday school development work. During the first year after the inspection the head teachers mainly strived to adjust formal deficiencies in local steering documents. However, some of the deviations reported from the Schools inspectorate are regarding pedagogical problems that are complicated and difficult to handle. As interventions in many cases will show up much later the results are, for example as increased goal fulfilment, in this case, still an open question. Nevertheless, it seems obvious that the Schools Inspectorate must be seen as a result of the governing philosophy that denotes New Public Management NPM).

Reading comprehension in primary school: textbooks, curriculum and assessment

This study describes the reading comprehension processes present in the most widely sold textbooks at the fourth grade level in Portugal and discusses how they compare to international assessments of reading literacy. We adopted the Progress of International Reading Literacy Study framework to categorize the questions in the textbooks. Our analyses revealed that they focus heavily on the retrieval of explicitly stated information to the detriment of higher level comprehension skills. Portuguese fourth grade textbooks rarely challenge students to make connections between their knowledge and the ideas in the texts and to adopt a critical and evaluative reading stance. This is in sharp contrast to what students are asked to do in the Progress of International Reading Literacy Study, conducted every five years since 2001, and it may help explain the poor results Portuguese students have in national assessment and in PISA. The findings are discussed in light of the curriculum frameworks currently adopted in Portugal and suggestions are made as to how we can improve reading literacy achievement.

Improvements for ZCS-PWM commutation cell in high-power-factor preregulator application

A Summary of different topological arrangements concerning a ZCS-PWM cell is presented, based on the analysis of its application in boost rectifying preregulators, controlled by the technique of instantaneous average values of input current, with the purpose of obtaining high-input-power-factor rectifier and high efficiency in single-phase applications in telecommunication systems. The main characteristics of each switching cell are described, providing conditions to establish a qualitative comparison among the structures. In addition, experimental results are presented for a prototype of the latest version of the ZCS-PWM boost rectifier, implemented for processing normal values of 1200 W output power and 400 V output average voltage, at 220 V Input RMS voltage and 50 kHz switching frequency.

Experimental paracoccidioidomycosis in high and low antibody responder mice of Selection IV-A

High (H) and low (L) responder mice were selected for their ability to produce antibodies against sheep and human erythrocytes (Selection IV-A). In this selection, the difference in antibody responsiveness between H and L lines (HIV-A and LIV-A mice, respectively) was shown to depend mainly on macrophage function. The more rapid catabolism of antigens by macrophages in L mice has been suggested as the main cause of the low antibody production. Due to this high macrophage activity, L animals have been described as more resistant than H animals to intracellular pathogens. These animals were utilized as an experimental model of paracoccidioidomycosis. HIV-A and LIV-A mice were infected with Paracoccidioides brasiliensis by the intravenous route. As expected, H mice were more susceptible to P. brasiliensis with a shorter survival time and higher levels of specific antibodies when compared to L mice. Contrasting with the survival time, the lungs, spleen and liver from H mice showed typical nodular granulomas containing epithelioid and giant cells and few fungi. on the other hand, in LN-A mice, the lesions of these organs were characterized by looser granulomas with irregular borders and the presence of a large number of fungi, However, the adrenal gland showed different lesion patterns. In H mice these lesions were extensive and characterized by loose granulomas with numerous fungi, while in LIV-A mice the lesions were small and limited to the cortex. Moreover the HIV-A mice presented higher levels of serum corticosterone when compared to LIV-A ones. The higher susceptibility of H mice could be attributed to the extensive lesions of the adrenal glands. These results suggest the use of the H line from the IV-A Selection as an experimental model for further studies of adrenal involvement in paracoccidioidomycosis.

Sexual harassment in Dentistry: prevalence in dental school

Objective: Sexual harassment is unlawful in all work and educational environments in most nations of the world. The goals of this study were to describe the sexual harassment prevalence and to evaluate the experiences and attitudes of undergraduate students in one dental school in Brazil. Material and Methods: An 18-item questionnaire was administered to 254 dental students with a completion rate of 82% (208). Students were requested to respond to questions about their background and academic level in dental school, their personal experiences with sexual harassment and their observation of someone else being sexually harassed. Bivariate statistical analyses were performed. Results: Fifteen percent of the students reported being sexually harassed by a patient, by a relative of a patient or by a professor. Male students had 3 times higher probability of being sexually harassed than female student [OR = 2.910 (1.113-7.611)]. Additionally, 25.4% of the students reported witnessing sexual harassment at the school environment. The majority of students did not feel professionally prepared to respond to unwanted sexual behaviors. Conclusion: These findings demonstrate that sexual harassment can occur in a dental school setting. There is a need for ongoing sexual harassment education programs for students and university staff. Increased knowledge of sexual harassment during graduation can better prepare dental professionals to respond to sexual harassment during their practice.
