Ansiedad ante las ciencias y pruebas de evaluación científicas: efectos del nivel académico y género

2019

Resumen En este trabajo se hace una primera aproximación a la ansiedad de los estudiantes de secundaria ante las ciencias. Se han aplicado a 175 estudiantes de educación secundaria de diferentes cursos dos cuestionarios validados y una prueba de evaluación de competencias científicas. Un cuestionario mide la ansiedad ante diversos contextos científicos y el otro evalúa la ansiedad generada por una prueba de evaluación de ciencias. El análisis de los resultados obtenidos por medio de pruebas Anova evidencia que: a) la ansiedad ante situaciones científicas es mayor que en otras situaciones y disminuye significativamente con el aumento del nivel académico; b) la ansiedad generada en la prueba …

Autentiskie video materiāli skolēnu klausīšanās prasmju pilnveidei angļu valodas stundās 8. klasē

2022

Diplomdarbā tiek pētīts, kā iespējams pilnveidot 8. klases skolēnu klausīšanās prasmes, izmantojot autentiskos video materiālus angļu valodas stundās. Darbs sniedz ieskatu klausīšanās prasmju nozīmē komunikācijā un autentisko video materiālu izmantošanā angļu valodas stundās. Izvēlētā pētījuma metode bija gadījuma pētījums kādā no Latvijas vidusskolām. Skolēnu aptaujas, testi, skolēnu atsauksmes un intervijas ar trīs angļu valodas skolotājām tika izmantotas kā datu ieguves metodes. Iegūtie dati liecina, ka autentisku video materiālu izmantošana angļu valodas stundās, pozitīvi ietekmē skolēnu klausīšanās prasmes: skolēniem ir vieglāk saprast dažādus akcentus, viņus mazāk ietekmē fona troksni…

Perfusion MR Imaging in Differentiating High-Grade from Low-Grade Gliomas

2011

To correlate perfusion MR imaging with histologic grade of cerebral gliomas. Materials & Methods Relative cerebral blood volume (rCBV) maps were determined in 22 patients with pathologically proved gliomas (11 glioblastomas, 8 anaplastic gliomas and 2 low-grade gliomas) by dynamic contrast-enhanced T2*-weighted MR imaging. MR examination was completed with conventional T1- and T2-weighted imaging. The rCBV maps were calculated with an independent workstation by fitting a gamma-variate function to the contrast material concentration versus time curve. Relative CBV ratios obtained between tumor and normal white matter were compared between glioblastomas, anaplastic gliomas and low-grade gliom…

The outcomes of national literacy programs on basic reading skills in familiar language among Zambian early graders

2016

In Zambia the Ministry of General Education implemented two national literacy programs in order to improve low levels of reading; the Primary Reading Program (PRP) implemented from 1999 to 2014 and the Primary Literacy Program (PLP) piloted in some schools in 2014 before being scaled up. This research examines the acquisition of basic reading skills among learners in familiar languages at the end of grade 2 in the two national literacy programs. I examined assessment results separately for each program and compared the two with each other. Outcomes were observed on the basis of the Early Grade Reading assessment test battery given to random samples of children (n=393) in 40 schools from 4 d…

The role of parents' and teachers' beliefs in children's self-concept development

2016

This study examined to what extent parents' and teachers' beliefs about children's abilities predict children's self-concept of math and reading ability development during the first grade, and whether these predictions depend on the child's gender and level of performance. One hundred fifty-two children and their parents and teachers were followed across first grade. The results showed, first, that the associations between teachers' beliefs and children's subsequent self-concept of ability depended on the level of the children's performance. Among high-performers, the higher the teachers' beliefs about their students' abilities in reading or in math, the higher the subsequent level of self-…

Home Literacy Activities and Children’s Reading Skills, Independent Reading, and Interest in Literacy Activities From Kindergarten to Grade 2

2020

According to the Home Literacy Model (Sénéchal and LeFevre, 2002, 2014), young children can be exposed to two distinct types of literacy activities at home. First, meaning-related literacy activities are those where print is present but is not the focus of the parent–child interaction, for example, when parents read storybooks to their children. In contrast, code-related literacy activities focus on the print, for example, activities such as when parents teach their children the names and sounds of letters or to read words. The present study was conducted to expand the Home Literacy Model by examining its relation with children’s engagement in literacy activities at home and at school as Fi…

Specificity of Reading Self-Efficacy Among Primary School Children

2018

We investigated the specificity of reading self-efficacy among second- to fifth-grade children in Finland (N = 1,327). Bandura (1997 Bandura, A. (1997). Self-efficacy: The exercise of control. New York, NY: Freeman. [Google Scholar] ) theorized that efficacy beliefs can be assessed at different levels of specificity; however, empirical support for this view is scarce among young children. Efficacy beliefs targeting reading-related activities were assessed at three specificity levels (general, intermediate, and specific). Confirmatory factor analysis revealed that these specificity levels are separable, but correlated, and the structure was invariant across gender and grade level. Self-effic…

Herbal medications for anxiety, depression, pain, nausea and vomiting related to preoperative surgical patients: a systematic review and meta-analysi…

The primary outcomes were anxiety, depression, pain and PONV. We used the Grading of Recommendations Assessme…

Mirizzi syndrome type V complicated with both cholecystobiliary and cholecystocolic fistula: a case report

2021

Abstract Mirizzi syndrome (MS) is a common bile duct (CBD) obstruction caused by extrinsic compression from an impacted stone in the cystic duct or infundibulum of the gallbladder. Patients affected by MS may present abdominal pain and jaundice. A 37-year-old male with neurologic residuals post-encephalitis arrived at the emergency department reporting abdominal pain, jaundice and fever. An ultrasound of the abdomen identified cholecystolithiasis with a dilated CBD. He did not undergo CT or MRI due to poor compliance and parents’ disagreement. Eventually, they accepted to perform endoscopic retrograde cholangiopancreatography, which diagnosed MS with both cholecystobiliary and cholecystocol…
