ResumenEn este artículo se analizan algunos anclajes teóricos del Modelo para el Desarrollo y Evaluación de Competencias Académicas. Inicialmente se revisa el concepto de competencias y sus posibilidades de trasladarlo a momentos de práctica docente y de evaluación de competencias. Específicamente, se abordan conceptos relacionados con competencias y competencias docentes. De los dos dispositivos que el modelo integra, aquí se aborda el de evaluación de competencias docentes, concebido como un momento más de su desarrollo y se proponen estrategias e instrumentos centrados en la evaluación auténtica de competencias docentes que permitan evaluar profesores en procesos de formación centrados en sus producciones. Dentro del modelo, se destaca al portafolio docente como una estrategia para la formación y evaluación de profesores y como un dispositivo de práctica reflexiva que contribuye a los procesos de formación y evaluación de competencias docentes.
Palabras clave: competencias, competencias docentes, evaluación de competencias docentes, portafolio docente.
Assessment of Teaching Skills in the DECA Model: Theoretical Anchors AbstractThis article discusses some theoretical anchors of the Model for Development and Assessment of Academic Skills. It initially reviews the concept of skills and the possibility of going to moments of teaching practice and skill assessment. It specifically addresses concepts related to skills and teaching skills. We herein address one of the two devices included in the model: the assessment of teaching skills, conceived as one more moments of their development; strategies and tools are proposed focused on an authentic assessment of teaching skills to evaluate teachers in their training processes, focusing on their productions. Within this model, the Teaching Portfolio is stressed as a strategy to train and evaluate teachers.
Five N-p-phenyl substituted benzamidines were studied by DC and DP polarography in a wide pH range. Coulometric results show that the overall processes are four-electron reductions. Logarithmic analysis of the waves indicate that the process are irreversible. The influence of the pH on the polarographic parameters was also studied. A UV spectrophotometric study was performed in the pH range 2-13. In basic media some variations in the absorption bands were observed due to the dissociation of the amidine group. A determination of the pK values was made by deconvolution of the spectra. Correlations of both the electrochemical parameters and spectrophotometric pK values with the Hammett substituent constants were obtained.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
