The research paper presented to explore valid, practical, and effective e-learning media. Reflectig the purpose of paper, this study is to improve critical thinking skills, to obtain an overview at high levels and increasing students' critical thinking skills including ability. The hypothesis is as a rational decision-making process on what believed is, through the aspect of providing basic explanations, building basic skills, concluding, making further explanations, and strategies and tactics in the lesson planning course, at the Faculty of Tarbiyah and Teacher Training at UIN Maulana Malik Ibrahim Malang. The paper explained ADDIE development model which included the design, development, analysis, implementation and evaluation stages which reffered research and development (R & D). The data for testing e-learning media in learning and tests of critical thinking skills carried out from fourth-semester students . The study used the One Group Pretest-Posttest Design for trial design. The results concluded the average percentage of feasibility value of the e-learning media from the three validators was 86.6% with very feasible criteria, the critical thinking ability instrument was 79.9% through feasible criteria. E-learning media used in a limited trial that obtained an average score of 82.4% for lecturers and students with practical criteria. E-learning media is improving critical thinking skills effectively which indicated changes in students and critical thinking test presented the results from 56.7 to 81.3. The findings showed that the e-learning media is valid, practical, and an effective criteria to improve students' critical thinking skills. Keywords: E-learning, learning strategies, critical thinking skills, tactics;

This article is intended to highlight the linguistic principle proposed by anthropological linguists, “Language is a mirror of the culture.” The purpose of study attempts to explore foreign language teaching and learning from the perspective of language shapes thought and to improve language learning through a cross a cross-cultural communication. The first part of this article, the linguistic principle, is reflected in the Sapir–Whorf hypothesis or the Whorfian hypothesis briefly highlighted. Second part focuses on the practical use of the Whorfian hypothesis for teaching English as a foreign language (TEFL), especially cross culture understanding (CCU) and the English teaching for specific purposes (ESP).

The current study investigated learners views towards the teachers' switching to the mother tongue in English as a foreign language (EFL) classes in secondary school in Algeria. It aimed at shedding some light on learners’ views towards the teachers’ switching to the mother tongue and different functions of code-switching (CS). A total of 120 secondary school learners participated in the study. The study concluded that learners have positive views toward the teachers' use of their mother tongue in EFL classes. It is used mainly to translate unknown vocabulary and explain grammar lessons.

More efficient instructional models that encourage students to engage more actively in their education are essential in today’s world. How information can be found and exchanged, as well as how explanations are delivered, have been shaped by technology. The outcomes demonstrate that mobile learning (m-learning) has enhanced collaboration among instructors and learners, provided immediate feedback, increased student participation and engagement, allowed for authentic learning and evaluation, and supported learning communities in higher education institutions. There was also a change in the teachers’ instructional methods. Students will benefit from simple learning activities, convenient communication, and coaching provided through mobile devices. This study recommends using a learning-based convolutional neural network (CNN) technique to improve students’ English-speaking fluency. In addition, communication between teachers and children in remote areas becomes easier through an interactive system, making both sides more accessible. As a result, it is advisable that educational institutions continually develop innovative teaching techniques that bridge face-to-face and formal-informal learning in the educational setting. The article discusses the background of mobile learning and how it might enhance e-learning as a whole. The m-learning approach is described in this paper as a future version of e-learning. In comparison to the next generation of educational systems, it will be extensively offered and simple to operate for any individual interested in learning. The article also discusses the benefits and potential drawbacks of mobile learning in current educational institutions.

Fake accounts on online social networks are increasing today with an increase in the number of active social network users. Social media websites allow users to share thoughts, facts, views and re-sharing these into various networks. Social media platforms provide users with enormous valuable information but with this great amount of information in social media, many issues like fake profile, online hacking have also grown. The fake profiles in online social sites create fake news and share unwanted material which contains spam links that affect natural users. The massive issue in social media communication networks is spam and it is necessary to identify fake profiles to stop spam. In this paper, a supervised machine learning algorithm called support vector machine (SVM) is used to identify fake accounts on social media effectively. In order to automatically identify fake online profiles, Random Forest classifier is used with SVM. With this concept, it can be applied online easily to identify millions of accounts that cannot be examined manually. The result of this model is compared with other identification techniques and the results show that the proposed algorithm performs better with high precision and recall. This method efficiently safeguards social media networks from online threats and attacks.

As is only natural, British English has undergone a change in its use of salutations. An important question is whether there has been significant influence from immigrants and/or other varieties of English on how British salutations are used, and, if so, how this is realised. We approach the analysis by evaluating how salutations have evolved and are evolving in appropriateness in spoken and written contexts. A finding from the data is that polite salutations appear to be becoming more generalized, i.e. more neutral. This paper draws on data from contemporary English in social, academic and YouTube texts, in both in formal and informal spoken and written contexts, as well as from the last few decades, exploring social, cultural and pragmatic meanings of salutations, with attention given to academic, social and stylistic uses such as when addressing strangers or the humorously ironic.
