abstract the current study set out to address the issue as to whether the implementation of portfolio assessment would give rise to iranian pre-intermediate efl learner autonomy. participants comprised 60 female in pre-intermediate level within the age range of 16-28.they were selected from among 90 language learners based on their scores on language proficiency test -key english test. then, t...
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
to explore the potential for in vitro rapid regeneration of fagonia indica burm., cotyledon explants were obtained from 10-day old aseptically germinated seedlings that cultured on ms medium which supplemented with 1.0-5.0 µm 2,4-d. callus was initiated from cotyledon explant on ms medium supplemented in all concentrations of 2,4-d investigated. 2,4-d was more effective than iaa and naa for cal...
Lisianthus (Eustoma grandiflorum cv. White) is an ornamental plant which has suitable marketing due to a variety of flower colours. The aim of the present study was to evaluate the effect of plant growth regulators on propagation and rooting of this plant. Axillary bud (node) was used as explants and MS medium supplemented with 0, 0.1, 0.2 and 2 mg/L of NAA and BA was applied. The results showe...
plant regeneration was achieved in verbascum speciosum schard. via organogenesis and somatic embryogenesis by culture of mature embryo explants. two types of calli, embryogenic and non-embryogenic, were induced from mature embryo explants on murashige and skoog (ms) medium supplemented with different concentrations of benzyl adenine (ba) and α-naphthalene acetic acid (naa). in order to further ...
the present study was conducted to investigate the role of summary in teaching grammar process on pre-university students. to this end, 48 male pre-university students in semnan were participants. they were math class that we called experimental group and science class as control group. in order to make sure there was no significant difference in proficiency level of two groups. a pre-test wa...
To explore the potential for in vitro rapid regeneration of Fagonia indica Burm., cotyledon explants were obtained from 10-day old aseptically germinated seedlings that cultured on MS medium which supplemented with 1.0-5.0 µM 2,4-D. Callus was initiated from cotyledon explant on MS medium supplemented in all concentrations of 2,4-D investigated. 2,4-D was more effective than IAA and NAA for cal...
Plant growth regulators (PGRs) have an important role in callus induction and organogenesis of plant explants cultured in vitro conditions. Callus has a proper potential for plant regeneration through indirect organogenesis and embryogenesis as well suspension culture, genetic transformation and production of secondary metabolites. In current experiment, leaf explants of Petunia × hybrida F1 we...
abstract this study aimed at investigating the possible relationship between self-assessment in writing and self-regulation of iranian efl learners. the main purpose of the study was not only to report and inform about this relationship, but also to investigate and find practical outcomes of the incorporation of self-assessment in writing, such as improving writing skill. the research was carr...
the present study was conducted to investigate the effect of implicit focus on form through input flooding and the effect of noticing, explicit focus on form on linguistic accuracy. to fulfill the purpose of the study, 86 iranian pre-intermediate efl learners of one of the language institutes were chosen by means of administering ket as the homogeneity test. these learners were pretested throug...
