Dijital teknolojilerin gelişmesiyle yaşamın her alanında kolaylıklar yaşanmaya başlamıştır. Bu teknolojiler, kolaylıkların yanı sıra riskleri de beraberinde getirmektedir. Zararlı içerikler, siber zorbalık, pornografi, cinsel içerikli mesajlar gibi riskler dijital araçlarla birlikte evlere kadar rahatlıkla girebilmektedir. Bu risklerden en çok etkilenmesi beklenen grup çocuklardır. Çocukların gelişiminden birinci derecede sorumlu olan ebeveynlere bu noktada önemli sorumluluklar düşmektedir. Ebeveynler, çocuklarını dijital teknolojilerden kaynaklanan risklerden korumak için dijital çağa ayak uydurmalıdır. Bu çalışmanın amacı dijital ebeveynlik yeterlik alanları ve göstergelerinin belirlenmesi ve belirlenen göstergelere dayanarak geliştirilecek bir araçla ebeveynlerin öz yeterliklerinin çeşitli demografik değişkenler açısından incelenmesidir. Tarama modelinde desenlenen çalışma iki aşamadan oluşmaktadır. Birinci aşamada alanyazın taraması ve uzmanlarla gerçekleştirilen bir odak grup görüşmesi sonucunda dijital ebeveynlik yeterlik alanları ve göstergeleri belirlenmiştir. İkinci aşamada ise Dijital Ebeveynlik Öz Yeterlik Ölçeği geliştirilerek, Eskişehir ilinde yaşayan 576 ebeveynin dijital ebeveynlik öz yeterlikleri ebeveyn rolü, internet kullanım deneyimi, gelir durumu, meslek ve eğitim durumu değişkenlerine göre incelenmiştir. Dijital ebeveynlik yeterlik ve göstergeleri başlangıçta yedi farklı boyuttan oluşmuş ve bu boyutlara göre Dijital Ebeveynlik Öz Yeterlilik Ölçeği hazırlanmıştır. Geliştirilen ölçeğin faktör yapısı farklı ebeveyn örneklemleriyle gerçekleştirilen açımlayıcı (n=520) ve doğrulayıcı analizlerle (n=556) irdelenmiştir. Yapı geçerliği çalışmaları sonrasında dijital okuryazarlık, dijital güvenlik ve dijital iletişim olmak üzere üç faktör altında toplanan göstergelerin ebeveyn rolü, internet kullanım durumu, gelir durumu, meslek ve eğitim durumu değişkenler açısından farklılık sergilememiştir.

Modulation of pump phases required for suppressing stimulated-Brillouin scattering is shown to cause large power changes in both the amplified and wavelength-converted signals when dual-pump fiber-optic parametric amplifiers are used. The physical origin of power changes is related to pump-amplitude modulations caused by fiber dispersion. Analytical as well as numerical calculations show that the signal-to-noise ratio of the signal or idler may reduce to below 23 dB when pump phases change rapidly with a sharp rise time.

Literacy is a fundamental skill to function in society. However, hearing impaired are severely disadvantaged in literacy development by lack of access to language's phonemic system. Recent developments in information and communication technologies stimulated technology integration endeavors in special education field. Hearing impaired children’s literacy instruction stands a fruitful area of technology integration. Former studies generally reported development or examination of supportive tools like visual dictionaries, sign language support, vocabulary drills or storybooks. However, few studies developed an overall approach and reported whole technology integration procedures. This study reports findings from a research which investigated the affordances of mobile devices in hearing impaired children’s literacy instruction. Two mobile applications were built from scratch and optimized through design based research. Furthermore, affordances and integration guidelines of these applications were investigated in a case study. The research was conducted in Anadolu University’s Applied Research Center for Hearing Impaired Children (İÇEM). Participants of the study are hearing impaired children studying at İÇEM in 2013-2014 and 2014-2015 academic years. Data sources of the project were observations, video recordings, audio recordings of expert panels and semi-structured interviews. The data were analyzed inductively using NVivo 10 software. Results suggested significant increase in student motivation towards the technology enriched instructional environment. This paper summarizes design and optimization studies along with technology integration guidelines to hearing impaired children’s literacy classes.

Developments in information and communication technologies caused an increase in the possession of digital tools and facilitated their use. The use of digital tools, especially the internet, now starts below the age of two. In this sense, during early childhood, parents have a great responsibility as they are primarily responsible for their children’s “digital exposure.” They need mediation strategies to determine their children’s use of digital tools. This study aims to examine the parental mediation situations of the parents of preschool children. This study, conducted as a survey model, adapted the Parental Mediation Scale to the preschool level as a data collection tool. The participants of the study consisted of 108 parents of preschool children. The results of the study determined that the parental role (mother‒father) and educational status of parents affected parental mediation strategies; whereas, the number of children, internet usage experience, income status, and the age of the parents or children did not affect said strategies. The qualitative analysis indicated that the parents have many concerns about the social‒emotional and physical problems that may occur due to internet use in children from an early age. It is among the other qualitative results that parents prefer more direct intervention techniques and technical solutions to protect their children from the risks of the internet. As a result of the research, this study presents suggestions to parents and researchers for future studies on children’s conscious use of digital tools.

As the use of digital tools and the Internet becomes widespread and easier, the age of use is also decreasing. The decrease in the age of use makes opportunities as well as risks an important factor in digital environments. Children who are not aware of the risks in these environments may be exposed to various risks, especially as the age of Internet usage decreases. Parents are primarily responsible for protecting their children from risks in these environments. Parents can protect their children if they use digital media consciously and safely. In this context, the aim of this study is to investigate the parent’s conscious and safe use of the Internet across Turkey. In accordance with this purpose, the study was designed as a survey study and the data of the study were collected from 9581 parents from 26 provinces with the Conscious and Safe Use of the Internet questionnaire developed by the researchers in the study. Descriptive statistics (%, f, X ̅, SS), t-test for independent samples, one-way analysis of variance (ANOVA), and correlation were used in the analysis of the data. As a result of the analysis of the data, it was determined that the parents’ use of the Internet on weekdays and weekends was similar, but this situation differed in children. It has also been determined that the leading situations that worry parents in digital environments are the harmful and illegal content and excessive time spent in these harmful and illegal environments.
