Relationship between meta-level variables and science achievement of secondary school studies

EFFECTIVENESS OF CONCEPTUAL CHANGE STRATEGIES IN SCIENCE EDUCATION: A META-ANALYSIS Paçacı, Çağatay; Özdemir, Ömer Faruk; Üstün, Ulaş; Department of Secondary Science and Mathematics Education (2022-6-29) There is extensive literature focusing on students’ misconceptions in various subject domains. Several conceptual change approaches have been trying to understand how conceptual change occurs to help learners handle these misconceptions. This meta-analysis aimed to integrate studies investigating the effectiveness of three types of conceptual change strategies; cognitive conflict, cognitive bridging, and ontological category shift in science learning. We conducted a random-effects meta-analysis to calculate...
Differential response to doxorubicin in breast cancer subtypes simulated by a microfluidic tumor model Özçelikkale, Altuğ; Noe-Kim, Victoria; Elzey, Bennett D.; Dong, Zizheng; Zhang, Jian-Ting; Kim, Kwangmeyung; Kwon, Ick Chan; Park, Kinam; Han, Bumsoo (Elsevier BV, 2017-11-01) Successful drug delivery and overcoming drug resistance are the primary clinical challenges for management and treatment of cancer. The ability to rapidly screen drugs and delivery systems within physiologically relevant environments is critically important; yet is currently limited due to lack of appropriate tumor models. To address this problem, we developed the Tumor-microenvironment-on-chip (T-MOC), a new microfluidic tumor model simulating the interstitial flow, plasma clearance, and transport of the d...
The immunological co-adjuvant action of liposomal interleukin-2: The role of mode of localisation of the cytokine and antigen in the vesicles Gürsel, Mayda (Informa UK Limited, 1998-01-01) In experiments designed to study the co-adjuvant action of interleukin-2, a model antigen (tetanus toroid) was passively entrapped in, or covalently coupled to multilamellar liposomes in the presence or absence of interleukin-2 (IL-2). When present, IL-2 was either co-entrapped with the toroid, entrapped alone in liposomes with toroid coupled to their surface, or coupled to the surface of liposomes with entrapped toroid. The role of spatial localization of IL-2 within the liposomal structure (vis a vis that...
Prospective evaluation of Vitamin K2, Raloxifene and their co-administration in osteoporotic rats Tasci, A. G.; BİLGİLİ, HASAN; Altunay, H.; Gecit, M. R.; Keskin, Dilek (Elsevier BV, 2011-07-17) In this study, therapeutic effects of Vitamin K2, Raloxifene and their co-administration on bone, uterus, blood and weight profiles were investigated with an ovariectomized rat model. Forty Wistar rats were divided into five groups (n = 8): Raloxifene (R), Vitamin K2 (K), Raloxifene + Vitamin K2 (R + K), ovariectomized controls (OVX) and Sham-operated controls (Sham). Treatment began 3 months after ovariectomy. Vitamin K2 and Raloxifene were administered 30 and 1.5 mg/kg/day separately and in combination fi...
The Role of contact in locals` attitudes towards refugees in Turkey Kahya, Gülin.; Öner Özkan, Bengi; Department of Psychology (2019) The present study aims to give an understanding on citizens` attitudes towards refugees in Turkey. Specifically, the main purpose is to explain the role of contact in positive and negative attitudes towards refugees. Attitudes Towards Refugees Scale (ATRS) which is a 5-point Likert-Type scale and consisting of two subscales was developed for the current study. The data for current study were collected from locals in several cities where refugees live intensely and interact with locals. 377 participants who ...
