Abstract: The current study sought to explore students’ perceptions of the Moodle platform pedagogical materials impact on students’ achievements: case of master one students at the department of English in Setif 2 University, Algeria. The used research tool is a questionnaire addressed to a sample of 100 EFL (English as a foreign language) master one students; the collected data from the students' questionnaire were analyzed using the Statistical Package for the Social Sciences (SPSS) and Excel programs, while the results were interpreted qualitatively. After analyzing the obtained data, it was concluded that Moodle platform significantly affects students’ achievement, for the majority of students indicated that Moodle contributed a great deal to their English language achievement. On the basis of the findings, pedagogical recommendations and implications are suggested to further enhance the effectiveness of the Moodle platform.

Abstract: In a step to internationalize its curriculum, the Algerian tertiary education authority has recently decided to make a significant shift in language of instruction from French to English. However, this transition may pose several challenges -and opportunities- that need to be carefully addressed to ensure its success; hence, it is essential to consider various aspects of the implementation process. For example, teachers, who have studied in French and have been using it for decades, may face initial difficulties in adapting to English as the language of instruction; therefore, properly equipping them with the necessary pedagogical skills to teach in English is crucial. Accordingly, the present study sought to understand teachers' perceptions of the support they require and the assistance they have received in implementing English as a medium of instruction. Understanding teachers' perspectives is crucial toeffectively facilitate the transition operation and to ensure the successful integration of EMI. To this end, this exploratory research has made use of surveys, which have been administered to a diverse sample of teachers who are undergoing or have recently undergone the training to make the transition from French to English as the language of instruction. The findings of this study provide insights about the participants’ attitudes towards EMI policy, their perceptions about the training programme in general and its adequacy to their needs in terms of linguistic knowledge, skills developments and teaching practices in particular. Moreover, the challenges and difficulties they have encountered while pursuing their training were exposed. Finally, the respondents have provided some recommendations they consider relevant to overcome the shortages of the training programme in particular and the integration of EMI in the tertiary level in Algeria as a whole.

The rapid development of blockchain technology has influenced several fields, including financial, healthcare, and supply chain systems. Recently, this technology has also been applied in education thanks to its unique features, including decentralization, trustworthiness, and security. Despite the bright side of blockchain, several concerns continue to undermine its adoption in education, such as legal, immutability, and scalability issues. Thus, a comprehensive survey about blockchain adoption in education deems necessary. This paper is a systematic literature review of blockchain applications in the education field. To do so, and after retrieving scientific publications on the topic, we classify the outcomes according to several categories. In this paper, we focus on two major themes: educational applications and benefits of blockchain integration. We combine the themes, then express and analyze the results as bubble charts. We analyze the proposed solutions in terms of the blockchain-based applications that have been developed for educational purposes and the benefits that the blockchain technology could bring to the education field. Finally, we describe some research gaps that need to be addressed and educational areas that could be explored for future research of blockchain adoption in education.

Facebook reviews contain reviews and reviewers' information and include a set of likes, comments, sharing, and reactions called Facebook Behaviors (FBs). We extend existing research on review helpfulness to fit Facebook reviews by demonstrating that Facebook behaviors can impact review helpfulness. This study proposes a theoretical model that explains reviews' helpfulness based on FBs and baseline features. The model is empirically validated using a real Facebook data set and different feature selection methods (FS) to determine the importance level of such features to maximize the helpfulness prediction. Consequently, a combination of the impactful features is identified based on a robust and effective model. In this context, the like and love behaviors deliver the best predictive performance. Furthermore, we employ different classification techniques and a set of influencer features. The results showed the performance of the proposed model by 0.925 of accuracy.The outcomes of the current study can be applied to develop a smart review ranking system for Facebook product pages.
