Since its inception in 1949, over 1,500 studies have investigated the validity of the GRE General Test to predict its performance criteria in higher education (Klieger, Bridgeman, Tannenbaum, & Cline, 2016). The present review paper sought to examine the predictive validity of the GRE General Test. Factors affecting the predictive validity (e.g., range restriction, compensatory selection, criterion unreliability, substantive and artifactual moderators, bias in testing, coaching effects, socioeconomic status (SES), gender, and a host of other intervening factors such as motivation, communication skills, etc.) have been discussed. A brief overview of GRE revised General Test format is also presented. After an account of the related review of the literature, a critical commentary on the predictive validity of the GRE General Test has been discussed with an emphasis on the role of criterion unreliability and SES factor effects. Keywords: Predictive validity, Graduate Record Examination (GRE), criterion unreliability, range restriction, compensatory selection

Large-scale standardized ESL tests such as the International English Language Testing System (IELTS) are widely used around the world to measure language proficiency of test takers and make different decisions based on their scores. Reading comprehension is an integral part of such tests which requires test takers to read passages and answer a set of questions. Although IELTS is a popular standardized test and is used for making critical decisions about test takers, very few attempts have been made to explore the validity of the exam and especially the reading part of the General Training Module. With this in mind, the purpose of the present study was to use a non-parametric item response theory model, called Mokken Scale Analysis (MSA), to examine the validity of the reading part of the General Training module of IELTS. To this end, item responses of 352 test takers to the reading comprehension test were analyzed. The results of item scalability, total scalability, and item-pair scalability showed that the reading part is a weak unidimensional scale. Using Monotone Homogeneity Model (MHM), monotonicity results also indicated that there are some items which violate the monotonicity assumption, although their values are insignificant. The analysis of unidimensionality using the AISP revealed that there are two scales and four unscalable items in the reading part. Therefore, Mokken scale analysis did not support the unidimensional structure of the reading part of the General Training module of IELTS.

This study examined the development of text complexity for the past 25 years of reading comprehension passages in the National Matriculation English Test (NMET) in China. Text complexity of 206 reading passages at lexical, syntactic, and discourse levels has been measured longitudinally and compared across the years. The natural language processing tools used in the study included TAALES, TAALED, TAASSC, and TAACO. To compare the differences across the years at various levels of text complexity, ANOVA and MANOVA tests were conducted. The results suggested that lexical level text complexity revealed the most evident changes throughout the years, lexical sophistication, density, and diversity levels of the most recent years of reading passages have increased remarkably compared to the early years. The syntactic level text complexity indicated a moderate elevation toward the recent years of reading passages. For the discourse level text complexity, regarding cohesion, insignificant fluctuation occurred throughout the years and the general trend was not necessarily increasing. Combined, the results indicated that text complexity of the reading comprehension passages in the NMET over the past 25 years had been steadily increasing by including more low frequency and academic vocabulary, diversifying vocabulary in the passages, and complicating sentence and grammatical structures. The results were further examined against the general curriculum standards and guidelines to analyze whether the changes were reflected in the policies. It showed that the exams required a much larger vocabulary size than the number indicated in the guidelines, suggestions for test designers and pedagogical practices were provided accordingly.

News headlines like other pieces of writings use rhetorical devices. They are regarded as the initial informative and persuasive part of news stories. The goal of the present study was to analyze COVID-19-related native and non-native news headlines chosen from two main online news websites in Iran and England in terms of number and degree of utilization of sub-types of rhetorical devices. To this end, the 6-week corpus including 489 headlines relevant to corona-virus news (282 headlines selected from the BBC and 207 from the Tehran Times) were analyzed. Shams (2013) and Picello (2018) taxonomies were used to analyze all news headlines. The findings showed that ten rhetorical devices were found in these headlines. Alliteration was used most frequently, following closely behind were metonymy, rhyme, rhetorical question, depersonalization, hyperbole, metaphor, pun, cliché, and euphemism. Both alliteration and metonymy were frequently used in the headlines of the news stories. However, just simile and allusion were found in the Tehran Times headlines, but not with high frequency. The findings can provide insights into the understanding of rhetoric-specific conventions in news headlines for ELT teachers and students. Also, English teachers can use news headlines as authentic teaching materials in their language classrooms.

The current study investigated the impact of an interventionist model of dynamic assessment, using a repetitive process of pretest-teach-posttest design, on Iranian EFL learners’ reading comprehension and classroom engagement. To this end, 40 intermediate participants were selected through convenient sampling from among the English majors of a university in Kerman, Iran, and assigned to two control and experimental groups, each including 20 students. Then, during 4-month period, the experimental group was exposed to reading comprehension class, using an interventionist model of DA, while the control group did not receive ant dynamic assessment program. At the end of the treatment, the participants’ scores on the pretest and post-test were statistically compared. The obtained results revealed that the experimental group significantly outperformed the control group on the scales of reading comprehension skill. A change was also observed in the classroom engagement of the experimental group, but not for the control group. Indeed, the results showed that dynamic assessment can boost participants' performance in a practical and effective way, not only in terms of reading performance but also in terms of motivating more classroom engagement among EFL learners. This finding has implications for teachers to design more efficient courses which are the ultimate goal of education.  

Measurement has been ubiquitous in all areas of education for at least a century. Various methods have been suggested to examine the fairness of education tests especially in high-stakes contexts. The present study has adopted the newly proposed ecological approach to differential item functioning (DIF) to investigate the fairness of the Iranian nationwide university entrance exam. To this end, the actual data from an administration of the test were obtained and analyzed through both traditional logistic regression and latent class analysis (LCA) techniques. The initial DIF analysis through logistic regression revealed that 19 items (out of 70) showed either uniform or non-uniform DIF. Further examination of the sample through LCA showed that the sample is not homogeneous. LCA class enumeration revealed that three classes can be identified in the sample. DIF analysis for separate latent classes showed that three serious differences in the number of DIF items identified in each latent class ranging from zero items in latent class 3 to 43 items in latent class 2. The inclusion of the covariates in the model also showed that latent class membership could be significantly predicted from high school GPA, field of study, and acceptance quota. It is argued that the fairness of the test might be under question. The implications of the findings for the validity of the test are discussed in detail.

The popularity of integrating technology in language instruction and its fundamental effect on the language learning dimensions has been widely acknowledged whereas learners’ motivation and attitude are expected to be improved in a web-based Computer-assisted language learning (CALL) environment. Therefore, this paper aimed to investigate the Iranian EFL learners’ motivation to learn English and attitude in a CALL environment. The participants of this study were 120 intermediate EFL learners from two private English language institutes in Isfahan, Iran. They were divided into two equal groups; one experimental group (EG) and one control group (CG). Then, a motivation questionnaire pretest was administered out to check the participants’ motivation at the beginning of the course. As the treatment, the EG learners were taught through CALL-based instruction and the CG learners were taught traditionally. After the treatment, a posttest of motivation and an attitude questionnaire were administered. The outcomes indicated that the CALL-based instruction promoted the participants’ motivation as checked by the Motivation Questionnaire. Moreover, as measured by a 20-item A-CALL attitude questionnaire, it was discovered that the learners in the EG had positive attitudes toward using CALL-based instruction. In light of the findings, a number of conclusions are obtained and several implications are put forward.

 This s tudy aims to research the origin and development of temporary landscapes, combining the research progress of temporary landscapes in China and other regions in the world, and propose the development trend of temporary landscapes in the future. As a unique form of open space, the temporary landscape has the characteris tics of "time limit," guidance, flexibility, and functionality. It is a spatial s trategy for the temporary occupation of land in urban cons truction. This article firs t introduces the temporary landscape background, combs the temporary landscape's development and connotation, and puts forward the temporary landscape concept based on summing up previous s tudies. Then, s tarting from three aspects: the type mechanism, design practice, and comprehensive functional benefits of temporary landscapes, this paper focuses on the research progress of the phenomenon of temporary landscapes in China and abroad in recent years. Finally, it makes a comparative analysis of the research, summarizes the differences in the s tudy of temporary landscapes between China and other regions, and proposes prospects for future research trends combined with the international development situation. 

Phenomenology is one of the outs tanding theoretical paradigms in contemporary s tudies in architecture and urban planning. However, the phenomenology of place in artworks, especially painting and drawings (visual arts), through architectural modalities could be a subs tantial attempt and a new subject that needs more s tudies. The purpose of current research is to achieve a method based on which the phenomenon of place in the visual arts could interpret and explained more accurately. For this aim, a qualitative and descriptive method is applied. In this s tudy, based on the theories of Martin Heidegger and Edward Ralph on the one hand and the ideas of Chris tian Norberg-Schultz, on the other hand, a framework for the phenomenological s tudy of the place has been proposed in three s tages of description, analysis, and explanation. Besides, the drawings of Sohrab Sepehri, one of the famous contemporary artis ts of Iran, have been s tudied as an example by applying this framework to show the efficiency of the proposed framework and method. The results of this s tudy show that the interpretation of artworks based on these three s tages consis tent with the s tage of phenomenological reduction and cons titution which is common in phenomenology. Sohrab Sepehri's drawings were well in line with the phenomenological concepts of place and its components and variables introduced in this research. The challenges of applying this framework discussed and enhancing its validity by further s tudies in the works of other artis ts, recommended.
