The general consensus on the invaluable contributions of audio-visual materials based on cognitive theory of multimedia learning (CTML) to enhancing the quality of language classes has turned them into indispensable tools which teachers utilize for more effective teaching of different language skills. The primary aim of this study was to explore the effect of audio visual aids on reading skill at university level. The secondary aim was to find out if this change in materials could have any impact on the motivation and attitudes of the students toward English learning. To this end, this quasi-experimental study adopted a pre-test post-test research method. A total of 256 General English university students were divided to experimental (n=184) and control (n=81) groups. The experimental group received audio-visual aids as the treatment while the control group was taught by a conventional text-based method, commonly practiced in General English classes at Tabriz University of Medical Sciences (TUMS). The reading section of preliminary English test (PET) and Gardner’s attitude and motivation test battery (AMTB) were used for data collection. The results of independent samples t-test and Mann-Whitney tests revealed that the students provided with audio-visual materials obtained greater reading outcomes and also showed more positive attitudes and higher motivation toward English learning. Thus, our research revealed that the higher productivity and livelihood of reading classes can be tangible even in the in the narrow space of a single university semester.

Robinson’s Cognition Hypothesis and Skehan’s Limited Attentional Capacity Model provide the major impetus for this study. The present article reports the findings of a between-subject factorial experimental research study which explored 1) the effects of increased cognitive task complexity, manipulated through the intentional reasoning demands and number of elements on the lexical and syntactic complexity, accuracy, and fluency (CAF) of EFL writers’ productions; and 2) the joint effects of cognitive task complexity factor and learners’ language learning aptitude (Low vs. High) on the written output. Firstly, we gave Carroll and Sapon’s Modern Language Aptitude Test (MLAT) to 226 participants and then did a random stratification of the low- and high- aptitude learners into three groups. The participants received letter writing tasks with different cognitive complexity levels (low, medium, and high). The findings indicated that increasing cognitive task complexity resulted in significantly higher lexical and syntactic complexity and lower fluency, whereas no significant effect was found on writing accuracy. Moreover, the statistical results revealed no significant interaction effect between task complexity factors and learners’ language aptitude. With regard to the first objective of the study, the findings supported the predictions of Cognition Hypothesis while it is not the case in relation to the second objective of the study.

This study aimed at examining the main and interaction effects of increased intentional reasoning demands, planning time, and also language learning aptitude on syntactic complexity, accuracy, lexical complexity, and fluency (CALF) of 226 EFL learners’ performance on letter writing tasks. The participants were first randomly assigned to three experimental groups to be given a task with differing degrees of reasoning demand (low, medium, and high) to each group. Then, within each reasoning group, we reassigned an equal number of high- and low- aptitude learners to Planning and No-planning groups by random stratified sampling. The results revealed that (a) increasing task complexity with regard to the amount of intentional reasoning demands resulted in greater lexical and syntactic complexity and less fluency while no significant effect was observed on accuracy; (b) increasing task complexity through planning time led to significantly lower syntactic complexity and fluency; (c) reasoning demands and planning time had a significant interaction effect on accuracy; and (d) the interaction effect of language aptitude was significant with neither planning nor reasoning factor, but a three-way interaction effect was found on accuracy. The findings are discussed in relation to cognitive task complexity (CTC) models which were the main impetus for this study.

Reading comprehension ability consists of multiple cognitive processes, and cloze tests have long been claimed to measure this ability as a whole. However, since the introduction of cloze test, different varieties of it have been proposed by the testers. Thus, the present study was an attempt to examine the relatedness of Cloze-Elide test, Multiple-choice (MC) cloze test, and C-test as three different types of cloze procedure used for measuring reading comprehension. To this end, one C-test consisting of four short texts, one fixed ratio (n=7) multiple-choice cloze test, and one cloze-elide test were prepared from reading passages with similar readability levels. The participants of the study were 30 (male &female) freshman university students majoring in English literature. The results of ANOVA test showed that there were not any statistically significant differences at the 0.05 level of significance among the performance of the students on the three tests measuring their reading comprehension. Therefore, it was concluded that against the advocates of each test who claim superiority of it over the other types, these three types of cloze tests in this study assessed the reading comprehension in a similar way. So, the testers can be confident to make use of these tests as reading comprehension tests interchangeably.
