in recent years, there has been a growing interest among researchers to investigate the relationship betweenteacher self-efficacy and classroom behavior management, especially students misbehavior. therefore, this study aimed to comparatively investigate english and arabic teachers’ use of different behavior managementstrategies, their self-efficacy, and their success in an iranian context. th...
to evaluate the effect of various levels of nitrogen fertilizer on nitrogen use efficiency and grain yield of canola cultivars, a split plot experiment based on randomized complete block design was conducted in 2007. factors were: nitrogen fertilizer at four levels (zero, 50, 100 and 150 kg/ha) in the main plots and canola cultivars at three levels (‘clover’, ‘opera’ and ‘okape’) in the sub plo...
In order to investigate the effects of different nitrogen fertilizer levels and water stress during milky and dough stages on grain yield, yield components and water use efficiency of corn hybrid SC 704 (late maturing, non prolific and dent type), a field study was conducted. The factorial design of the study comprised of a randomized complete block with four replications. Four levels of nitro...
current studies in second language (l2) learning have revealed the positive role of corrective feedback (cf) in both oral and written forms in different language features. the present study was an attempt to investigate the effect of both direct and indirect written corrective feedback (wcf) on the use of grammatical collocations in l2 writing. the study also sought to examine whether the effec...
This study was designed and implemented to investigate the yield and agronomic characteristics in three differently maturing corn (Zea mays L.) hybrids (SC704, SC500, and SC260) using four nitrogen (N) levels (0, 80, 160, and 240 kg N ha-1, from Urea, N= 45%). The experiments were conducted in Zabol (South-West of Iran) and Isfahan (Central Iran) in 2014 and 2015, respectively, using a split-pl...
Improving the efficiency of resource utilization has received increasing research attention in recent years. In this study, we explored the potential physiological mechanisms underlying improved grain yield and water-use efficiency of winter wheat (Triticum aestivum L.) following organic fertilizer application. Two wheat cultivars, ChangHan58 (CH58) and XiNong9871 (XN9871), were grown under the...
this study explored reading strategy use of tefl ma students when they read academic research articles in english. the purpose of this study was to investigate how this group of readers typically approaches reading academic research articles related to their field of study, and also what they do in reading such research articles. the aim of the present study was bilateral. first, the researcher...
abstract the present study deals with a comparison between reactive and pre-emptive focus-on-form in terms of application and efficiency. it was conducted in an intermediate english class in shahroud. 15 male learners participated in this research and their age ranged from 18 to 25. a course book, new interchange 3, and a complementary book were used. every session the learners gave lectures o...
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
