The authors carried out a review study on the pedagogy for teaching communication skills (CS) in engineering higher education institutions with a view to firstly present the trend on the instructional pedagogical approaches used in an engineering classroom and secondly, to show the impact of these approaches on learners' development of CS. In order to address the research questions, we adopted 'Systematic Literature Review' as a research methodology and reviewed empirical research studies published between the year 2001 and 2021 exploring electronic database. Having followed the review protocols, we finally selected 26 research articles for a detailed analysis and synthesis. In regard with number of publications, the trends placed the USA at the top position which was followed by India. Overall, we found a lack of experimental research, subsequently a lack of evidence-based teaching practice, in the domain of pedagogy for developing CS leading to the assumption of still prevalent conventional lecture method of teaching in the CS classroom which is further held responsible for poor CS among engineering graduates. The teaching trend indicates that engineering institutions across nations are increasingly becoming aware of evidenced-based teaching approaches and are adopting innovative, learner-centered methods blended with ICT tools to facilitate the process of developing CS, along with other generic skills which has positive impact on learners' development of skills and attributes. The findings have implications for both; research and classroom teaching. [ABSTRACT FROM AUTHOR]

Applying artificial intelligence in education is relevant to addressing the current educational crises. Many available solutions apply Convolutional Neural Networks (CNNs) to help improve educational outcomes. Therefore, a series of works have been developed integrating techniques in different educational contexts, for instance, in online teaching practices. Given the various studies and the relevance of CNNs for educational applications, this paper presents a systematic literature review to discuss the state-of-the-art. We reviewed 133 papers from the IEEE Xplore, ACM Digital Library, and Scopus databases. Based on our revision, we discuss characteristics of studies such as publication venues, educational context, datasets, types of CNNs models, and performance of models. We evidence that the literature regarding CNNs still misses more studies discussing educational problems faced by Global South students, considering both teaching and learning perspectives. Such a population cannot be neglected during experiments due to specific educational weaknesses (for example, basic skills) demanding personalized solutions. • A systematic literature review of 133 published papers. • China covered most publications, followed by India. • There is a research gap regarding using CNNs in some regions of the Global South. • The main educational context with CNN applications is students' performance.
