ABSTRACT
Resumo A autoeficácia dos docentes e seu acesso a recursos podem influenciar a transição do ensino presencial para o ensino remoto emergencial. Este estudo objetivou construir e verificar evidências de validade das escalas de Autoeficácia e Acesso a Recursos de Docentes do Ensino Superior que passaram pela transição para aulas remotas. As escalas foram construídas e submetidas à validação semântica e por juízes. A coleta de dados foi realizada a distância com 135 professores. Foram realizadas análises descritivas, exploratórias e confirmatórias. Ambas as escalas apresentaram cargas fatoriais acima de 0,4. A escala de Autoeficácia docente apresentou-se unifatorial com bom índice de consistência interna (α = 0,95) e bons indicadores de ajuste (x 2 : 256,794; df: 131; CMIN/DF: 1,96; GFI: 0,89; RMSR: 0,05; CFI: 0,93; TLI: 0,91; RMSEA: 0,07). A escala de acesso a recursos apresentou-se com dois fatores e obteve bons índices de consistência interna (α entre 0,80 e 0,88) e bons indicadores de ajuste (x 2 : 67,99; df: 31; CMIN/DF: 2,19; GFI: 0,90; RMSR: 0,12; CFI: 0,94; TLI: 0,92; RMSEA: 0,094). Este estudo amplia o conhecimento a respeito da transição do ensino presencial para o ensino remoto, e traz implicações práticas que poderão auxiliar no planejamento e desenvolvimento das ações educacionais.
Abstract Teachers' self-efficacy and access to resources can influence the transition to emergency remote teaching. This study aimed to build and verify validity evidences of the Self-Efficacy and Access to Resources scales of Higher Education Teachers who underwent the transition to remote classes. The scales were constructed and submitted to semantic and expert validation. Data collection was carried out remotely with 135 teachers. Descriptive, exploratory and confirmatory analyzes were carried out. Both scales presented factor loadings above 0.4. The Teacher Self-Efficacy scale was unifactorial with a good internal consistency index (α = 0.95) and good adjustment indicators (x2: 256.794; df: 131; CMIN/DF: 1.96; GFI: 0.89; RMSR: 0.05; CFI: 0.93; TLI: 0.91; RMSEA: 0.07). The access to resources scale had two factors and obtained good internal consistency indexes (α between 0.80 and 0.88) and good adjustment indicators 67.99; df: 31; CMIN/DF: 2.19; GFI: 0.90; RMSR: 0.12; CFI: 0.94; TLI: 0.92; RMSEA: 0.094). This study expands knowledge regarding the transition from face-to-face teaching to remote teaching, and brings practical implications that may help in the planning and development of educational actions.
Resumen La autoeficacia de los docentes y el acceso a los recursos pueden influir en la transición a la enseñanza remota de emergencia. Este estudio tuvo como objetivo construir y verificar evidencias de validez de las escalas de Autoeficacia y Acceso a Recursos de Profesores de Educación Superior que atravesaron la transición a clases remotas. Las escalas fueron sometidas a validación semántica y de expertos. La recolección de datos se realizó de forma remota con 135 docentes. Se realizaron análisis descriptivos, exploratorios y confirmatorios. Ambas escalas presentaron cargas factoriales superiores α 0,4. La escala de Autoeficacia Docente fue unifactorial, con buen índice de consistencia interna (α = 0,95) y buenos indicadores de ajuste (x2: 256,794; gl: 131; CMIN/DF: 1,96; GFI: 0,89; RMSR: 0,05; CFI: 0,93; TLI: 0,91; RMSEA: 0,07). La escala de Acceso a Recursos tuvo dos factores y obtuvo buenos índices de consistencia interna (α entre 0,80 y 0,88) y buenos indicadores de ajuste X 67,99; df: 31; CMIN/DF: 2,19; GFI: 0,90; RMSR: 0,12; CFI: 0,94; TLI: 0,92; RMSEA: 0,094). Este estudio amplía el conocimiento sobre la transición de la enseñanza presencial a la enseñanza remota, y aporta implicaciones que pueden ayudar en la planificación y desarrollo de acciones educativas.
ABSTRACT
Abstract Graduate Specialization courses were created to train and prepare professionals for the labor market. The aim of this investigation is to discuss issues about these graduate courses, the quality of the courses offered, their disadvantages and contributions, given their relevance to the labor market. The retrieved studies were indexed in the databases: Web Science, Proquest, BVS and Scielo. The keywords used were: "lato sensu graduate", "MBA", "quality" and "employability", 419 articles were retrieved, of which 31 were analyzed. The inclusion criteria: 2000 to 2019; scientific articles, open access for download; peer-reviewed journals; in Portuguese, English and Spanish; build and/or validated measurement instruments and quality of the literature. The main results indicate that professionals, when investing in graduate courses, believe in the possibility of insertion in professional life, ascension or career redirection. These programs have shown a loss of quality over time, and this is due to the lack of official monitoring and regulations, in addition to the lack of credibility in the learning offered. This study aims to contribute to the discussion and reflection on - graduate specialization courses, the outdated education system and, in this regard, to raise new scientific concerns that may arise from this research survey.
ABSTRACT
The aim of this study was to evaluate the effects of replacing Tifton-85 hay (0, 20, 40, 60 and 80 % on a dry matter basis) with water hyacinth hay (Eichhornia crassipes) on intake and digestibility of nutrients, feeding behaviour, rumen and blood parameters of sheep. Five uncastrated male sheep, cannulated in the rumen, with an average body weight of 40 kg were assigned in a 5 × 5 Latin square design. The water hyacinth hay contained 870 g/kg dry matter (DM), 159 g/kg crude protein (CP), 547 g/kg neutral detergent fibre (NDF) and 461 g/kg total digestible nutrients (TDN). The DM intake and digestibility of NDF and non-fibre carbohydrates (NFC) were linearly reduced by replacing the Tifton-85 hay with water hyacinth hay. Similarly, there was a linear reduction of rumination time and efficiencies of feeding and rumination of DM and NDF. The concentrations of urea, glucose, AST and GGT in blood plasma were not changed by replacing the Tifton-85 hay with water hyacinth hay. Although water hyacinth hay reduced the intake and digestibility of some nutrients, the Tifton-85 hay replacement could be economically advantageous for sheep feeding.
