Safe building design by small architects: A design activity developed for elementary mathematics course

Karahan, Engin
© 2020, Ankara University. All rights reserved.This study aims to develop an acquisition-oriented STEM activity that primary school teachers can implement in the classroom. The design-based teaching activity developed and implemented within this study is intended to be presented as an example of an activity suitable for STEM education focused on mathematics lessons. The activity was developed in line with the design process indicators within the K-12 engineering education framework. The steps of this learning model are (1) problem and background, (2) plan and implementation, and (3) testing and evaluation. The activity particularly targets elementary school students produce an engineering design product using simple and low-cost materials. The four criteria presented to the students in this process were (1) apartments receiving light, (2) being earthquake resistant, (3) being economical and (4) aesthetics and marketing. Throughout the design process, the criterion that students had the most difficulty was observed as the sun exposure of the flats. Also, most of the students focused more on the aesthetic criterion than other criteria, and they emphasized this criterion most in the marketing process of their products.

Student and teacher evaluations about design based science education: “Heat insulation is a gain for country” activity Tasarım temelli fen eğitimine yönelik öğrenci ve öğretmen değerlendirmeleri: Isı yalıtımı ülke kazanımı etkinliği
Altan, Esra Bozkurt; Karahan, Engin (2019-01-01)
© 2019, Ankara University. All rights reserved.This study aimed to investigate students’ evaluations about “Heat Insulation is a Gain for Country” activity designed based on Design Based Science Education (DBSE) and the instructor’s views about her experiences during the activity. The participants of this single case study are 32 students and 1 teacher. The evaluations of the students were collected via DBSE Student Evaluation Survey and focus group interviews, whereas teacher view data was collected via an...
Middle school students’ perceptions about twenty-first-century learning practices in science classes: A multidimensional approach Ortaokul öğrencilerinin fen bilimleri dersindeki 21. yüzyil becerilerine ılişkin algıları: Çok boyutlu bir yaklaşım
Uğur, Ünzile Elif; Sungur, Semra (2021-01-01)
© 2021, Hacettepe University. All rights reserved.The purpose of this study was to determine middle school students’ perceptions about twenty-first-century learning practices that they experience in their science classes. For the specified purpose, firstly, Students’ Perception of 21st Century Learning Practices instrument was validated for Turkish middle school students. Then, students’ perceptions were examined in terms of learning processes for 21th century learning (i.e. self-directed learning, collabor...

© 2021 Karadeniz Technical University. All rights reserved.Online crowdsourcing sites/platforms have become popular in recent years, and the first aim of this study is to uncover what crowdsourcing resources language learners in Turkey, Bosnia and Herzegovina, the Republic of North Macedonia and Poland know about and use. The other two goals of the study are to uncover what crowdsourcing games or websites the students in the studied countries utilise as in- or/and outside-class activities, how enjoyable the...
Moving STEM Beyond Schools: Students' Perceptions about an Out-of-School STEM Education Program
Baran, Evrim; BİLİCİ, SEDEF CANBAZOĞLU; Mesutoğlu, Canan; Ocak, Ceren (2016-01-01)
Recent reports call for reformed education policies in Turkey in accordance with the need to develop students' knowledge and skills about STEM education and improving STEM workforce in the country. This research implemented an integrated out-of-school STEM education program for 6th grade students who come from disadvantaged areas in a large urban city in Turkey. The study investigated students' perceptions about the STEM activities implemented in the program. Forty 6th grade students (15 female) studying in...
Finite-Aperture Microwave Bessel Beams with Vortex Twisting, Fracturing, and Dynamic Phase-Shift Control
Yurchenko, Vladimir; ÇİYDEM, MEHMET; Koç, Seyit Sencer (2022-01-01)
© 2022, Electromagnetics Academy. All rights reserved.—Finite-aperture microwave vortex beams of various structures in the near-, middle-, and far-field propagation zones have been simulated. The decay of external sidelobes leading to the end of non-diffractive propagation within a fraction of the near-field zone is observed. A ring source of the vortex beams with phase-shift and frequency-sweep control of angular modes and polarization patterns through the use of patch antenna arrays of varying polarizatio...
