Computer-Assisted Instruction With Virtual Reality: Exploring Its Impact on Science Learning and Gender Differences
(Duzce University, Faculty of Education, 2024) Özkan, Y.; Bilgin, E.A.; Uğraş, G.
The purpose of this study was to investigate the impact of computer-assisted instruction [CAI], incorporating virtual reality [VR], on the academic achievement of 6th-grade students in Science courses. The research employed a quasi-experimental design with a pre-test and post-test control group. Lessons in both experimental and control groups were conducted according to the 5E instructional model. While the experimental group utilized CAI, including VR, the control group followed traditional teaching methods. The study involved 52 students at a public school in the eastern region of Türkiye. A researcher-developed achievement test on the Respiratory System was used as the primary data collection tool. Quantitative data were analyzed using descriptive statistics, dependent and independent t-tests, and the Mann-Whitney U test. Findings revealed that CAI significantly improved students’ academic achievement in Science, whereas gender did not affect performance outcomes. In the experimental group, there was no significant difference in achievement between students with or without personal computers. However, unexpectedly, students in the control group with personal computers outperformed those without. The study highlights the effectiveness of CAI, including VR, in enhancing academic performance and underscores the importance of equitable access to technological resources. These findings have implications for education policymakers, teachers, and parents aiming to improve Science education quality and promote equal learning opportunities through technological integration. © 2024, Duzce University, Faculty of Education.

Juvenile Scleroderma and Calcinosis Cutis: Case Report
(2009) Tekeoǧlu, I.; Hiz, O.; Özkan, Y.; Söker, D.; Özçelik, R.
Calcinosis cutis is a tissue calcification of cutaneous tissues. It is divided into four categories: dystrophic, metastatic, idiopathic and iatrogenic. The dystrophic type, which develops secondary to non-metabolic diseases, is the most common type. It may be observed in collagen tissue diseases including scleroderma, CREST syndrome, dermatomyositis and systemic lupus erythematosus. In this report, we present a 9-year-old patient with swelling and roughness on both hands and arms, solid nodules on the anterior aspect of both arms next to the elbows- more prominent on the left side- who was under follow-up for juvenile rheumatoid arthritis (JRA) for the last 3 years. Histopathological examination of the cutaneous biopsy material obtained from a nodular lesion and magnetic resonance images revealed the diagnosis of scleroderma and calcinosis cutis. In accordance to the result of the assessment of the patient, we suggest that scleroderma should always be kept in mind in the differential diagnosis of calcinosis cutis in patients with JRA.

Osteoporosis in a Male Patient With Leprosy: a Case Report
(2010) Hiz, Ö.; Özkan, Y.; Gülcü, E.; Tekeoǧlu, I.
Leprosy is a chronical infectious disease caused by Mycobacterium Leprae involving peripheral nerve, skin, reticuloendothelial system, eyes, testicles and other internal organs. Low bone mineral density in male patients with leprosy due to inactivity, neuropathy, musculosceletal pathology, testicular atrophy and hypogonadism is possible. In this report, we present a male case with hypogonadism and testicular atrophy caused by leprosy and aim to discuss its effects on androgen and bone mineral density.
Rheumatoid Arthritis-Like Hand Deformities in a Case With Osteogenesis Imperfecta: a Case Report
(2010) Hiz, Ö.; Ediz, L.; Ceylan, M.F.; Özkan, Y.; Tekeoǧlu, I.
Osteogenesis imperfecta is a disease that involves mesodermal tissues and characterized by decreased bone mass and increased bone fragility. Bone fractures developed due to ligamentous laxity, low energy trauma and joint deformities and contractures due to dislocations may be seen during the disease process. For that reason, it could be confused especially with rheumatoid arthritis. In this article we presented a case with osteogenesis imperfecta that misdiagnosed as rheumatoid arthritis because of joint deformities and common joint pain.
