Textbooks play a pivotal role in language learning classrooms. The problem is, among a wide range of textbooks available, which one is more appropriate for a specific classroom and a group of learners. In order to evaluate ELT textbooks, theorists and writers have offered different kinds of evaluative frameworks based on a number of principles and criteria. This study evaluates one example of s...

Derived from the emerging paradigm shift in English language teaching and assessment, there has been a renewal of interest in dynamic assessment (DA) to be used as an alternative to the traditional static testing in language classrooms. However, to date, DA practice has been mostly limited to clinical treatments of children with learning disabilities, and it has not been widely incorporated int...

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...

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 present study aims to analyze the English language teachers’ perceptions and practices in Saudi Arabia from perspective of environmental education. drive is firstly record scrutinize regarding incorporation education as part ELT. Secondly, it explores whether or not they integrate concerns into their teaching materials practices. For this purpose, mixed-method research was used using a ques...

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...
