Adopting a phenomenological approach, the research involves 51 pre-service middle school mathematics teachers enrolled in a mathematical modeling course in mathematics education. Data were collected through assignments, videos, reports from the Academic Learning Management System, GeoGebra records, and semi-structured interviews. The data obtained from the Academic Learning Management System and GeoGebra were analyzed via descriptive analysis, whereas the semi-structured interviews were examined via content analysis. Pre-service middle school mathematics teachers experienced difficulties in modeling competencies, particularly in applying subject matter knowledge effectively and integrating technology into the modeling process. Technology-enhanced learning environments emerged as a critical support mechanism for fostering the use of content knowledge and promoting mathematical modeling as a problem-solving approach. Structured guidance and the integration of interactive digital tools within flipped learning environments proved to be effective in addressing the challenges encountered during the modeling tasks.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">342-365</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Sema  Unluer</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">CHALLENGES IN ONLINE LEARNING ENVIRONMENTS: FROM THE PERSPECTIVE OF HEARING-IMPAIRED UNIVERSITY STUDENTS AND THEIR LECTURERS</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">case study</style></keyword><keyword><style  face="normal" font="default" size="100%">covid -19 pandemic</style></keyword><keyword><style  face="normal" font="default" size="100%">hearing impaired</style></keyword><keyword><style  face="normal" font="default" size="100%">online learning</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2024</style></year><pub-dates><date><style  face="normal" font="default" size="100%">April/2024</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://oaji.net/articles/2023/457-1715415088.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">82</style></volume><pages><style face="normal" font="default" size="100%">Continuous</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The global COVID-19 pandemic has led to significant challenges in Turkey, as in many other countries, in the transition from face-to-face to online education at all levels of education. This shift has brought forth numerous obstacles, particularly for d/Deaf and hard-of-hearing (d/Dhh) university students. Hence, this research aims to identify the challenges encountered during online learning amidst the pandemic at the School for the Handicapped (SfH), the only institution in Turkey providing vocational higher education to hearing-impaired students. Conducted as a qualitative case study at the SfH, the research involved 20 hearing-impaired students and 19 faculty members as participants. Data obtained from the Mergen Anadolu Learning Management System platform, WhatsApp Platform and other platforms, was used for online education. Interviews, open-ended questionnaires, and the researcher’s journal were compiled and analyzed inductively. Findings from the study highlighted a multitude of challenges encountered in the online learning process, affecting both faculty members and students at the SfH. The challenges encountered by participants in online learning at the SfH were found to be related to difficulty in understanding lessons, lack of subtitles and sign language translation, difficulty accessing computers and software, Internet problems, low camera usage, low motivation, and lack of interaction. </style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">294-312</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Ignacio Jr., A.

This research aimed to explore the teacher education mathematics major students' experiences with taking undergraduate mathematics courses online, precisely the benefits and challenges they encountered, and in what way they dealt with these challenges. The design used in this study is qualitative exploratory research by distributing open-ended questions to selected Bachelor of Secondary Education in mathematics students (N = 76) from a state university in the province of Bulacan, Philippines. Data were explored through thematic coding. The results indicated that among the gains of taking mathematics courses online, the students mostly gained from a convenient study time to access applicable web-based references and resources. In spite of unpredictable internet networks, limited teacher and peer interaction, vague learning content and discussions, some distractions, and a lack of satisfactory learning resources, independent and self-paced study paired and fired with enough self-motivation are suggested.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">102-116</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Maja Kerneža</style></author><author><style face="normal" font="default" size="100%">Kordigel Aberšek, M.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">ONLINE READING IN DIGITAL LEARNING ENVIRONMENTS FOR PRIMARY SCHOOL STUDENTS </style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">digital literacy</style></keyword><keyword><style  face="normal" font="default" size="100%">e-reading</style></keyword><keyword><style  face="normal" font="default" size="100%">internet reciprocal teaching</style></keyword><keyword><style  face="normal" font="default" size="100%">online learning</style></keyword><keyword><style  face="normal" font="default" size="100%">primary school</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2022</style></year><pub-dates><date><style  face="normal" font="default" size="100%">December/2022</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://oaji.net/articles/2022/457-1672601156.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">80</style></volume><pages><style face="normal" font="default" size="100%">Continuous</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Learning environments and teaching methods have been constantly changing over the past decades. As the shift in the learning environment is primarily toward a physical to an online learning environment, this study examines how to enable younger students to select appropriate content for learning in digital learning environments that they can then successfully read and evaluate using appropriate strategies. The study is based on 54 in-depth case studies. Using the Internet reciprocal teaching method (IRT), 54 implementers trained 54 primary school students from first to fifth grade in basic computer skills, Internet information searching, and website navigation, as well as analysing data obtained using the TICA Phase 1, 2, and 3 Checklists, the implementers' report, and the children notes in a text editor. Triangulation of the data in combination with selected statistical methods shows that there are differences in the use of the method between students according to age. While the latter can use an unadopted form of the method, younger students need some adjustments, which are suggested in the light of previous research. </style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">836-850</style></section></record></records></xml>
