The present article arises from a three-year cross sectional investigation into English Language Teaching (ELT) in secondary schools in Iran and the role of Communicative Pedagogy within this. The study has examined the extent of communicative pedagogy within the Iranian national ELT curriculum, the ELT programme and to some extent the English language coursebooks used in secondary schools. Wha...

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...

To define the C. elegans aging process at the molecular level, we used DNA microarray experiments to identify a set of 1294 age-regulated genes and found that the GATA transcription factors ELT-3, ELT-5, and ELT-6 are responsible for age regulation of a large fraction of these genes. Expression of elt-5 and elt-6 increases during normal aging, and both of these GATA factors repress expression o...

the study of teachers’ pedagogical knowledge base (pkb) to discover how teachers think and work is attracting increasing attention in elt. against this background, the present study aimed at probing the likely variations in efl teachers’ pedagogical knowledge base as a function of their teaching license status. to this aim, six teachers (two standard-licensed, two alternatively-licensed, and tw...

Teachers need to know new applications for developing online materials and then they should become aware of different ways to present them to online audience. This study tries to help ELT teachers to overcome challenges and difficulties of vodcasting by recognizing their social and biological motives (Activity Theory), and using Visual Thinking Strategies (VTS). It can alter teachers’ negative ...

We have identified a gene encoding a new member of the Caenorhabditis elegans GATA transcription factor family, elt-3. The predicted ELT-3 polypeptide contains a single GATA-type zinc finger (C-X2-C-X17-C-X2-C) along with a conserved adjacent basic region. elt-3 mRNA is present in all stages of C. elegans development but is most abundant in embryos. Reporter gene analysis and antibody staining ...

We describe the elt-4 gene from the nematode Caenorhabditis elegans. elt-4 is predicted to encode a very small (72 residues, 8.1 kD) GATA-type zinc finger transcription factor. The elt-4 gene is located approximately 5 kb upstream of the C. elegans elt-2 gene, which also encodes a GATA-type transcription factor; the zinc finger DNA-binding domains are highly conserved (24/25 residues) between t...

The Caenorhabditis elegans GATA transcription factor elt-1 has previously been shown to have a central role in the specification of hypodermal (epidermal) cell fates and acts several cell divisions before the birth of hypodermal cells. Here we report that elt-1 also has essential functions during subsequent development. Reporter gene studies show that elt-1 expression is maintained in lateral s...
