Supporting novice mathematics teachers: The impact of an e- mentoring and video-based professional development program on teachers? noticing skills

Karadeniz Technical University Scientific Research Foundation [7178]The study was supported by Karadeniz Technical University Scientific Research Foundation with the project number 7178.This paper focuses on e-mentoring of novice mathematics teachers as professional development, and reports findings of the e-mentoring practices enriched with videos to improve noticing skills of novice teachers. A single group pre- and post-test study was conducted with the participation of 17 mentees, novice middle school mathematics teachers. Participants' noticing skills were assessed through a whole-class teaching video shown to them before and after the intervention. The responses of the teachers to the video assessment were analyzed considering attending, interpreting and decision-making dimensions of noticing. The results revealed that the ementoring program improved the novice mathematics teachers' noticing skills significantly in all dimensions.WOS:000978797700007Emerging Sources Citation IndexarticleUluslararası işbirliği ile yapılmayan - HAYIRMayıs2023YÖK - 2022-2

Optical whitening of cationised cotton: effect on whiteness and whiteness tint

In this study, the effect of cationisation on optical whitening was examined. For this purpose, the whiteness index and whiteness tint of optically whitened pre-cationised knitted cotton fabrics were analysed. The cationisation and optical whitening processes were carried out under different concentration levels, using the exhaustion method. The whiteness index and whiteness tint were calculated after colour measurements were taken. The experimental results were also analysed statistically using ANOVA. The whiteness index obtained from cationised fabric was lower than that of non-cationised fabrics. While the whiteness tint of cationised cotton fabric had a blue to greenish nuance, the non-cationised fabric had a reddish nuance.In this study, the effect of cationisation on optical whitening was examined.
