While existing literature highlights the advantages of video-based microteaching for teacher training, the specific uses and factors affecting their implementation remain underexplored. This research aims to address that gap by examining the impact of peer feedback in this context. The paper is couched from a social constructivist perspective, as outlined by Bandura's social learning theory, which suggests that individuals learn through observing and modelling others' behaviours. This qualitative study used a purposive sample of 20 third-year Bachelor of Education student teachers. Data was collected through observations, individual interviews, focus group interviews, and analysis of reflective documents. The collected data was thematically analysed. The findings suggest that using self-recorded microteaching videos and peer feedback effectively enhances preservice teachers' skills and reflective capabilities, aiding their transition into the teaching profession. It also boosts their pedagogic decision-making and professional development. The study recommends that teacher education programs implement clear guidelines for the peer feedback process, focusing on constructive feedback to create a collaborative and inclusive learning environment. https://hdl.handle.net/10481/104617 The role of cognitive, psycholinguistic, and neurological models in developing, diagnostic and treatment tools for language disorders Naima, Maouchi; Sidahmed, Bara This article aims to explain the role of cognitive, psycholinguistic, and neurolinguistic models that can be adopted as a theoretical basis for constructing diagnostic tools or therapeutic programs for developing oral language for children who have trouble in understanding and producing oral and written language. Based on a carefully selected theoretical background, an integrated treatment protocol was developed for deaf children with cochlear implants. This protocol is based on the neuropsychological linguistic model (MNPL) of Chevry-Muller (2007) to improve language reception and production, respecting all stages, from the initial level to the highest and most complex levels. It is currently undergoing psychometric testing to study its effectiveness and efficacy. https://hdl.handle.net/10481/104616 Language Development In Children Mebrouk, Guesmia Language development in humans is considered a process through which an individual's ability to use, employ, and understand language evolves, with the aim of communicating with others to meet various needs. This development encompasses all aspects of language, including vocabulary, grammatical structures, rhetorical devices, and other elements, leading up to pronunciation and understanding of meanings. It begins in the early stages of childhood and continues throughout the different stages of life. Language development is influenced by many factors, such as the environment—particularly the individual's interaction with family members including parents and siblings—as well as heredity, which includes the child’s innate abilities. Additionally, learning experiences and supportive educational tools play a role in the process of language acquisition. This study addressed several points, including: the concept and manifestations of language, the characteristics of language, language comprehension and meaning perception, the stages of language development in individuals, the factors affecting language development, and finally, the theories that have discussed language. https://hdl.handle.net/10481/104614 Effect of Plyometric Training Jump Techniques on Speed and Explosive Power of Lower Limbs in Football Players Loukia, Youcef Islam; Grine, Walid; Belfritas, Yacine This study examined the effects of plyometric jump training on speed and lower-limb explosive power in football players. Twenty U21 elite male players from Algeria's Association El Khroub club were randomly allocated into an experimental group (n=10) undergoing plyometric jump training and a control group (n=10) following conventional training. Performance was assessed using the 30-meter sprint test and countermovement jump (CMJ) test. Statistical analyses included independent/paired t-tests and two-way ANOVA. The study results revealed significant improvements in CMJ performance between pre- and post-tests (p<0.05; ES=0.63-1.31), with a pronounced main time effect (p<0.05; η²=0.693-0.935). The experimental group demonstrated superior CMJ gains compared to controls (p<0.05; η²=1.31). However, no significant 30-meter sprint enhancements were observed (p>0.05). While plyometric training proves effective for developing explosive power, its speed-related outcomes require cautious interpretation due to the study's limited sample size. The variability in training responses underscores the influence of program design factors (duration, volume, intensity). These findings highlight the necessity for tailored interventions addressing sport-specific speed physiology. Further research should incorporate larger cohorts and extended intervention periods to validate these observations. https://hdl.handle.net/10481/104613 Descriptive Analysis of the Developmental Trajectories of Longitudinal Morphological Segment Dimensions among Algerian Swimmers, Boys, Aged 11 Years Khalid, Saber; Kheireddine, Elhamici; Rachid, Meddah; Brahim, Belkacemi; Abdelhamid, Berdai The aim of this study is to examine the morphological characteristics of the longitudinal body segments of young, pre-pubescent swimmers (11 years old) undergoing growth. It also seeks to provide potential answers to certain questions concerning the health and growth status of Algerian child athletes and to present their profile in relation to existing international literature. Understanding the rate of morphological development of longitudinal segments and their homogeneity within overall body growth is also of particular importance for epidemiological studies in Algeria. We investigated Algerian male athletes, specializing in swimming, aged 11 years, from the regions of the Wilaya of Sétif and Algiers. The anthropometric measurements taken included: stature, sitting height, trunk length, upper limb length, arm length, forearm length, and hand length. The tests also encompassed the lower limb and its components: thigh, leg, and foot. Statistical analysis was performed using multivariate analysis, also known as Principal Component Analysis. This method was employed to extract redundancies and correlations between these segments, which explain the state of homogeneity and the representativeness of longitudinal development in relation to stature during this age period. The results indicate that the development and bodily growth of the segments during this age period are characterized by harmony and significant redundancy among body parts. This observation confirms the similar growth pattern to that mentioned and described in scientific literature.
