Trees provide a wide range of benefits to humans and other living organisms. An accurate method tree species identification will improve their management and conservation.  Also, tree identification and description are crucial for genetic study, biodiversity conservation, management and regeneration strategies. The conventional methods of tree identification are time-consuming and requires a high level of expertise, necessitating development of a more efficient tree identification means. In this research, a QR code system for tree identification was developed. Tree data were collected from campuses of two tertiary institutions in Akure, Nigeria: Federal University of Technology and Federal College of Agriculture. System design was built around a three-tier architectural model. PostgresSQL was used as the Database System, the lowest tier. The Middle tier is the Web Server, Apache HTTP Server.  Php 8.1 was the scripting language that communicates with the database. For the Client tier, HTML, CSS and Javascript were used. The QR code generator was developed using PHP 8.1. The PHP script used a QR code library to generate the QR code image. The QR code is linked to the website database containing all tree species information. The generated QR codes were attached to trees, and when scanned, the website is automatically launched and the tree information is retrieved. A survey was conducted to get end-users’ feedback within the study sites. The results obtained revealed that the QR codes are easy to use, and can make tree identification more interesting, thus increasing people’s knowledge about trees and improving Trees management.

Online learning has recently turned to one of the most well-known channels of education; however, the controversy over the quality and outcome of such online medium is still a concern. This study sought to determine the pros and cons of online courses as perceived by Iranian language teachers and learners. Two tailor-made questionnaires, along with a semi-structured interview, were used to collect the data. The participants were 71 college students who have experienced online educations and 31 language teachers who taught web-based classes in the Department of English Language Education at three universities in Iran, Isfahan, Sheikhbahaee, and Ashrafi. An overall analysis of questionnaires and interviews revealed that students and teachers could not find online education easier than its conventional counterpart. Online education provides teachers with a precise image of applying the appropriate teaching methodology in their online classes as well as enhancing their autonomy. The research recapped that online educators and administrators of faculties ought to lay the foundations for making the benefits of online education bold for learners. The findings may be a contributing factor for teacher educators to create the climate for professional development.

As the demand for online language education continues to grow, English teacherpreneurs play a significant role in shaping teaching practice and identity in virtual affinity spaces. This study examined the professional identity and practice of Iranian EFL teacherpreneurs in such spaces. The study adopted a qualitative approach and the data were collected through in-depth interviews and a focus group discussion. The findings of this research indicated that the participants as Iranian EFL teacherpreneurs in online affinity spaces possessed a wide range of positive traits and engaged in interactive and non-traditional teaching practices going beyond EFL traditional teaching practices. They also noted challenges being online English teacherpreneurs in Iran, highlighting a lack of financial support from mainstream education system and insufficient electronic facilities to create online content among others. This study has implications for different agencies in language teaching, including teachers and policy-makers in language education, raising their awareness regarding the identity and practice of online teacherpreneurs in virtual affinity spaces.  

The present investigation aimed at studying the impacts of Iranian EFL learners’ gender, age, field and degree of study on their perceptions of mobile affordances. To this end, 159 Iranian EFL students studying at university were asked to fill Mobile Affordance Inventory (Rostami, 2021). To analyze the data, Kolmogorov-Smirnov test, independent sample t-test, one way ANOVA, and Pearson’s correlation were run. The findings of the study indicated that no differences were found among EFL learners in using mobile learning affordances regarding their gender, degree, and field of study. Additionally, no significant relationship was found between the arcticians’ age and their mobile affordances. The results also showed that different affordances of mobile devices can provide new and important information for educators. They become more familiar with different mobile phones capabilities to use, and it makes their teaching more effective. Becoming familiar with affordances provides a situation for improving students’ learning as well as their self-control.

Abstract The necessity of using online education during the Coronal virus pandemic and the barriers created by the absence of face-to-face instruction has shifted the researchers’ focus to web-based instruction and assessment. In this regard, an explanatory sequential mixed-methods design was selected to consider the effects of web-based dynamic assessment (DA) on learners' grammar accuracy, autonomy, and attitudes. To this end, a convenient sample of 60 male English as a Foreign Language (EFL) learners was chosen and categorized into two groups of web-based dynamic assessment and a control group. The data collection tools were a pretest and posttest of grammar, a pretest and posttest of autonomy, and a semi-structured interview. The participants were exposed to web-based DA via a designed web based on the level and the students’ needs in grammar, whereas the learners in the control group learned the grammar through the traditional method of instruction. Based on the results of ANCOVA and Mann-Whitney U test, the learners’ grammar accuracy and autonomy mean scores in web-based DA increased compared to those of the control group. In addition, the results of interview showed that the learners had a positive attitude toward web-based dynamic assessment treatment. The results of the semi-structured interview with the experimental group verified the quantitative results. The platform and methods employed in this study suggest encouraging implications for the field of language instruction which will be discussed.
