This article explores the effectiveness of interactive teaching methods in improving English vocabulary acquisition among primary school students. The research focuses on various interactive strategies, such as games, role-plays, digital tools, and collaborative learning techniques, which engage learners in the vocabulary learning process. Findings from classroom observations and teacher interviews suggest that these methods significantly enhance students’ motivation, retention, and practical usage of new vocabulary. The article concludes with recommendations for English language teachers on incorporating interactive activities into their daily lesson plans to ensure more effective vocabulary instruction.

Menopause is a critical transitional phase in a woman’s life characterized by the cessation of ovarian function and the end of menstruation. It is often accompanied by a range of physical, emotional, and metabolic symptoms that vary in intensity and duration. Recent research indicates that vitamin D plays a significant role not only in bone metabolism but also in the modulation of menopausal symptoms. The aim of this study was to investigate the features of the menopausal course in women diagnosed with vitamin D deficiency and determine how hypovitaminosis D influences the severity of menopausal manifestations. The study revealed a notable correlation between low serum levels of vitamin D and the severity of vasomotor symptoms, mood disorders, sleep disturbances, and musculoskeletal pain. This research underlines the importance of monitoring and correcting vitamin D levels in peri- and postmenopausal women to reduce symptom burden and improve overall quality of life. The menopausal period represents a pivotal phase in the physiological aging process of women, characterized by profound hormonal, psychological, and metabolic transitions. Beyond the well-documented decline in estrogen levels, micronutrient imbalances—particularly vitamin D deficiency—have emerged as critical modifiers of menopausal health outcomes. This study explores the intricate interplay between hypovitaminosis D and the clinical progression of menopause, focusing on symptom intensity, systemic complications, and quality of life implications. The investigation, conducted on a representative cohort of postmenopausal women, revealed a significant amplification of menopausal discomfort in individuals with deficient serum vitamin D levels. Notably, manifestations such as thermal dysregulation, cognitive disturbances, emotional instability, and skeletal complaints were disproportionately prevalent in this subgroup. These findings suggest a potential therapeutic target in vitamin D optimization to mitigate the climacteric burden and promote healthier aging trajectories among menopausal populations.
