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...

In this work, an intervention was designed to contribute to the training of scientists, through redesigning the assessment of an authentic performance task. An analytic rubric to assess a laboratory report written as a scientific paper for a biochemistry course was created and validated. The agreement between referees was 70%. The analysis allowed...

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...

Authenticity has been identified as a key characteristic of assessment design which promotes learning. Authentic assessment aims to replicate the tasks and performance standards typically found in the world of work, and has been found to have a positive impact on student learning, autonomy, motivation, self-regulation and metacognition; abiliti...

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...

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...

The structure of phycobiliproteins and their spatial organization in the phycobilisome provide the environment for high efficiency in light harvesting and conduction towards photosystem II. This article focuses on the analysis of R-phycoerythrin, a light harvesting hexameric phycobiliprotein that is part of the phycobilisomes. The interaction surfa...

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...
