The purpose of the current study was to compare the repeatability of electromyographic linear envelopes (LE) of archery groups. Surface electromyography (EMG) signals of musculus flexor digitorum superficialis (MFDS) and extensor digitorum (MED) of 23 participants (seven skilled, six beginner archers and ten non-archers) were recorded during archery shooting. Two-second periods (clicker falls at first second) of 12 shots' EMG data were recorded, full-wave rectified and filtered (60 ms moving-average filter) for each participant's drawing arm. Repeatability was investigated by using a statistical criterion, variance ratio (VR). Archers' performances were evaluated in terms of FITA scores. The results showed that FITA scores were significantly correlated to the VRs of MFDS and MED. EMG LEs were more repeatable among archers than non-archers. Therefore, we inferred that VRs of MFDS and MED might be important variables for (a) assessing shooting techniques, (b) evaluation of archers' progress, and (c) selection of talented archers.

CLASSROOM MATHEMATICAL PRACTICES OF THE SEVENTH GRADERS ABOUT RATIO AND PROPORTION CONCEPTS Sözen Özdoğan, Sinem; Akyüz, Didem; Stephan, Michelle; Department of Elementary Education (2023-2-22) The purpose of this study is to examine the Classroom Mathematical Practices (CMPs) of seventh-grade students with regard to ratio and proportion concepts through the implementation of a specific instructional sequence. The study was conducted using an educational design research methodology and was based on the Classroom Hypothetical Learning Trajectory and related instructional sequence developed by Stephan et al. (2015). The instructional sequence was mainly carried out by an experienced middle-grade mat...
Dynamic frictional contact problems involving functionally graded materials Balcı, Mehmet Nurullah; Dağ, Serkan; Department of Mechanical Engineering (2018) The main aim of this study is to analyze the dynamic frictional contact problem of layered and functionally graded materials. Investigating contact problems including dynamic effects has a significant importance in mechanical engineering applications since many contact problems arise between moving structures. In moving contact problems, speed of the punch may not be so small to ignore dynamic effects. Hence, contact problem should be examined using elastodynamics theory. In this study, both frictional movi...
Metadrama, theatrıcalıty and performatıvıty ın samuel beckett’s late plays Eşberk, Hatice; Sönmez, Margaret Jeanne M.; İçöz, Nursel; Department of English Language Teaching (2013) In this study six of Samuel Beckett’s plays are analysed by concentrating on features that are considered within postmodern aesthetics. In doing so, the study is separated into three parts, being metadrama, theatricality and performativity. For each part two Beckettian plays are analysed. In the first section, Catastrophe and Krapp’s Last Tape are investigated in terms of their use of the metadramatic devices outlined by Richard Hornby. In the second part, the theatricality in Ohio Impromptu and Not I is st...
Assessment in the 5th grade mathematics classrooms: a case study of the teachers’ practices Uçar Sarımanoğlu, Nihan; Çakıroğlu, Erdinç; Department of Elementary Education (2016) The purpose of this study was to examine the mathematics teachers’ assessment practices in the 5th grades. In that manner, it was aimed to figure out the mathematics teachers’ classroom assessment procedures and their use of the assessment results. It was also aimed to understand teachers’ views about the students’ learning of mathematics, the factors affecting teaching mathematics, and their views about assessing students’ learning of mathematics. In order to achieve these purposes, a multiple case study d...
Examination of chemistry teachers' topic - specific nature of pedagogical content knowledge in electrochemistry and radioactivity / Aydın, Sevgi; Boz, Yezdan; Kondakçı, Esen; Department of Secondary Science and Mathematics Education (2012) The purpose of this study was to examine topic-specific nature of pedagogical content knowledge (PCK). Two experienced chemistry teachers’ PCK was examined in electrochemistry and radioactivity. To capture participants’ PCK, all PCK components were studied. To get deep and rich answers to research questions asked, qualitative methodology was used. Participants were selected through purposeful sampling. Data were gathered through card-sorting activity, Content Representation (CoRe), semi-structured interview...
