ABSTRACT Tests and examinations are widely used internationally. Despite their pervasiveness, they tend to measure lower order thinking skills in a decontextualized manner at a time when the literature frequently argues for the benefits of a richer, authentic approach to assessment. The focus of this paper is to improve authenticity in test assessm...
Article
Problem‐based learning using authentic material from the web was used to teach metabolism in a biochemistry course. In place of traditional lectures, students’ analyzed health or nutrition articles from newspapers and magazines, which were debatable from a scientific point of view, following the principles of problem‐based learning. A mixed method...

La forma en que se evalúan los aprendizajes tiene un impacto en la calidad del desempeño alcanzado por los estudiantes. En Educación Superior, este tipo de prácticas presenta dificultades: se tiende a utilizar formatos tradicionales de evaluación como son las pruebas de lápiz y papel, y se miden más las habilidades memorísticas que las de transfere...

The mineralized skeleton is a major evolutionary novelty that has contributed to the impressive morphological diversifications of the vertebrates. Essential to bone biology is the solidified extracellular matrix secreted by highly specialized cells, the osteoblasts. We now have a rather complete view of the events underlying osteogenesis, from a ce...
Article
The Runx2 transcription factor is a key regulator of osteoblast differentiation. In response to 1alpha,25 dihydroxy vitamin D3, Runx2 may interact with the 1alpha,25 dihydroxy vitamin D3 receptor (VDR) in the promoter of target genes, producing a synergic activation of their transcription. Previous studies have suggested that the motifs responsible...

Phycocyanin is a phycobiliprotein involved in light harvesting and conduction of light to the reaction centers in cyanobacteria and red algae. The structure of C-phycocyanin from Gracilaria chilensis was solved by X-ray crystallography at 2.0 A resolution in space group P2(1). An interaction model between two PC heterohexamers was built, followed b...

Full-text available
Numerous biological macromolecules are arranged in complex interaction systems, to perform their biological function. Phycobiliproteins, the main polypeptidic components of the phycobilisomes, are very good examples for explaining these interactions because their light harvesting and conduction function depend strongly on the three dimensional arra...
