İçerisinde bulunduğumuz dijital çağda öğrencilere 21.yüzyıl becerilerin yanı sıra dijital vatandaşlığın kazandırılması büyük önem arz etmektedir. Yüz yüze eğitimin başlangıcı olarak kabul edilen okul öncesi eğitimde teknolojinin kullanılması yönündeki görüşler gün geçtikçe artmaktadır. Yapılan çalışmalar sayesinde teknolojinin etkili ve doğru biçimde kullanıldığında fırsatları arttırdığı, ancak yanlış kullanıldığında zorlukları beraberinde getirdiği ve fiziksel aktivite düzeyinde azalmaya bağlı obezite gibi olumsuz etkiler yaratabileceği bilinmektedir. Bu nedenle okul öncesi öğretmenlerinin teknoloji, pedagoji ve alan bilgisinin birlikte kullanıldığı Teknopedagojik alan bilgisine diğer öğretmenlerden daha fazla ihtiyaç duyduğu düşünülmektedir. Bu çalışmada, okul öncesi öğretmenlerin Teknolojik Pedagojik Alan Bilgisi yeterliklerinin belirlenmesi amaçlanmıştır. Yapılan bu betimsel çalışma, Ankara’da okul öncesi öğretmeni olarak Milli Eğitim Müdürlüğü’ne bağlı okullarda görev yapan 1169 öğretmen ile yürütülmüştür. İlişkisel tarama modeli kullanılarak öğretmenlerin Teknopedagojik yeterlilikleri irdelenmiştir. Çalışmaya katılan öğretmenlerde Teknopedagojik yeterlilikleri eğitim düzeyi (lisans ve yüksek lisans) ve mesleki kıdeme göre farklılık gösterip göstermediği sorgulanmış, elde edilen verilerin analizleri sonucunda öğretmenlerin Teknopedagojik yeterliliklerinin yüksek düzey olduğu görülmüştür. Okul öncesi öğretmenlerinin lisans ve yüksek lisans yapmış olmaları ile mesleki kıdemlerinin Teknopedagojik yeterliliklerine etkisinin olmadığı görülmüştür.

Fundamental movement skills acquired during pre-school years provide the basis of normal motor development, positive self-image, self-perceived sports competencies in the adolescence. An instructional approach supported with visual materials may improve learning in pre-school children. The purpose of this study was to examine the effects of digital physical exercise videos on pre-school children's locomotor skill learning. A total of 906 children (662 Turkish and 244 Bulgarian), participated in the study as intervention (n = 442) and control (n = 464) groups. Each motor skill program consisted of video based 15-minute physical exercise for eight-weeks. Ulrich’s Test of Gross Motor Development was used for the assessment of fundamental motor skill performance at the beginning of the study as pre-test and at the end of the eight-week digital visual supported locomotor movement program as posttest. Two separate 2 × 2 (Group × Time) ANOVAs with repeated measures were used to analyze the improvement in locomotor skills performances of intervention and control groups. Results indicated significant Group × Time interactions for the locomotor sub-scale (p < 0.05). The intervention group showed a statistically significant improvement in locomotor skills, whereas control group did not show any significant change. The result provide evidence that locomotor motor skill performance may be improved via digital materials focused on locomotor skill development.

Vibration analysis seldom has been used in detecting structural and mechanical changes in physiologic and pathologic bone conditions. We sought to correlate natural frequency of the radius measured by vibration analyses with bone mineral density measured by dual-energy xray absorptiometry and quantitative computed tomography (including cortical thickness). Sixty sedentary men between 50 and 70 years old were deemed osteopenic or healthy. A higher natural frequency of the dominant and nondominant radius was seen in the healthy men compared with the osteopenic men. Natural frequency was consistent with bone mineral density in dominant and nondominant radius in both groups. Moreover, there was a correlation between bone mineral density measured by dual-energy xray absorptiometry and natural frequency in the dominant and nondominant radius. Cortical thickness of the dominant and nondominant radius also correlated with natural frequency. We concluded natural frequency measured by vibration analysis is a precise method for the assessment of structural properties of bone and correlates with the bone mineral density of the radius.

BackgroundObesity has become a major health issue in the world and directly reduces the quality of life. The aim of this study was to compare the effect of aerobic and resistance exercises on body composition and quality of life (QoL) in overweight and obese women. Method An experimental study involving 90 overweight/obese women aged between 20-45 years participated in the study voluntarily and were randomized into control (n=30), aerobic exercise (AE) (n=30), and resistance exercise (RE) (n=30) groups. Either AE or RE groups performed exercise for 60 minutes per day for 10 weeks, whereas the control group did not perform any exercise. The body composition and QoL of the women were measured before and after the exercise. ResultsBody weight, BMI, fat mass, and waist and hip circumferences decreased significantly in both AE and RE groups after the exercise intervention compared to the control group (p<0.05). In addition, quality of life sub-dimensions including physical health, psychological health, social relationship, and environment sub-dimensions improved significantly in the AE and RE groups compared to the control group (p<0.001). Post hoc Tukey test showed that AE was as effective as RE for improving body composition parameters and QoL sub dimension compared to control group. ConclusionThis study demonstrated that both AE and RE were effective in improving body composition and thereby increasing the QoL in overweight and obese women. Both AE and RE programs are effective and should be considered within any multicomponent therapy program in overweight and obese women.
