Learning through YouTube has become one of the main sources of learning in the student's life at the present time which provides illustrative images, scalability of knowledge, and ease of searching for sources of knowledge. It also provides the student with large areas of self-learning and the provision of knowledge according to the desire of the student. On the contrary, other learning sources, where knowledge and goals are limited as well as time and place. Therefore, the current study deals with knowledge of the students' performance in listening skills by using YouTube among students of non-native Arab speakers by adopting Connectivisim Theory. To achieve the objective of this study, the researcher intends to use the questionnaire survey to measure the effect of using youtube to increase the level of listening skills among non-native students of Arabic speakers. The study sample size was 144 students selected through the stratified sampling method from non-Arabic speaking students at the International Islamic Universiti Sultan Abdul Halim Mu'adzam Shah (UniSHAMS). The study used (SPSS,25) to investigate the hypotheses. Furthermore, the study showed that using YouTube has a highly significant impact on increasing listening skills for non-native students of Arabic speakers.

The present study aimed to assess metabolites heterogeneity among four major Cinnamomum species, including true cinnamon (Cinnamomum verum) and less explored species (C. cassia, C. iners, and C. tamala). UPLC-MS led to the annotation of 74 secondary metabolites belonging to different classes, including phenolic acids, tannins, flavonoids, and lignans. A new proanthocyanidin was identified for the first time in C. tamala, along with several glycosylated flavonoid and dicarboxylic fatty acids reported for the first time in cinnamon. Multivariate data analyses revealed, for cinnamates, an abundance in C. verum versus procyandins, dihydro-coumaroylglycosides, and coumarin in C. cassia. A total of 51 primary metabolites were detected using GC-MS analysis encompassing different classes, viz. sugars, fatty acids, and sugar alcohols, with true cinnamon from Malaysia suggested as a good sugar source for diabetic patients. Glycerol in C. tamala, erythritol in C. iners, and glucose and fructose in C. verum from Malaysia were major metabolites contributing to the discrimination among species. [ABSTRACT FROM AUTHOR]
