BACKGROUND Simulation-based learning is a common educational tool in health care training and frequently involves instructional designs based on Experiential Learning Theory (ELT). However, little research explores the effectiveness and efficiency of different instructional design methodologies appropriate for simulations. The aim of this study was to compare 2 instructional design models, ELT ...

Seam cells in Caenorhabditis elegans provide a paradigm for the stem cell mode of division, with the ability to both self-renew and produce daughters that differentiate. The transcription factor RNT-1 and its DNA binding partner BRO-1 (homologues of the mammalian cancer-associated stem cell regulators RUNX and CBFβ, respectively) are known rate-limiting regulators of seam cell proliferation. He...

after the teacher, the most important factor in foreign language classroom is the textbook. it is vital that the best possible text be chosen for each situation. even with the development of new technologies that allow for higher quality teacher-generated materials, demand for textbooks continues to grow, and the publishing industry responds with new series and textbooks each year. therefore, i...

Reflections on the relationship between Iranian ELT researchers and practitioners suggest that research-practice gap has been an endemic feature of our language education programs. This issue has recently become a prime concern for many educational researchers, policy makers and other stakeholders. As such, calls for empirical investigations of measures to be taken in order to improve the relat...

Gene regulation during development is an important biological activity that leads to synthesis of biomolecules at specific locations and specific times. The single tropomyosin gene of Caenorhabditis elegans, tmy-1/lev-11, produces four isoforms of protein: two from the external promoter and two from the internal promoter. We investigated the internal promoter of tropomyosin to identify sequence...

In the selection of a new textbook, it is important to conduct an evaluation to ensure that it is suitable. Evaluation is widely acknowledged as a powerful means of improving the quality of education. There are three methods of evaluation that can be used for evaluating English Language Teaching (ELT) textbooks. An evaluative checklist is one of these methods that can be used to help select the...

Cis-regulatory elements (CREs) are crucial links in developmental gene regulatory networks, but in many cases, it can be difficult to discern whether similar CREs are functionally equivalent. We found that despite similar conservation and binding capability to upstream activators, different GATA cis-regulatory motifs within the promoter of the C. elegans endoderm regulator elt-2 play distinctiv...
