Explorations to Overcome Socio-Economic Barriers in Learning and Thinking: A Flipped Classroom Study

The present study aims to examine the effect of the flipped classroom model on the academic achievement and critical-analytic thinking skills of students from different socio-economic backgrounds. For this purpose, two schools in the same province, attended by children from families with varying socio-economic levels, were included in the study. The study sample consisted of a total of 82 students: 30 from a secondary school with students from a low socio-economic background and 52 from another secondary school with students from a high socio-economic background in the 2021-2022 academic year. The study was designed based on the quasi-experimental design with pretest-posttest control groups. Experimental and control groups consisting of one class each, and four classes in total, were selected from the schools using the random assignment method. The total application period was 9 weeks while the duration of the experimental applications was 7 weeks (28 class hours). In the present study utilizing Edpuzzle, an online platform, interactive videos were developed in accordance with the learning outcomes of the course. Data were collected using the 25-item “Sun, Earth and Moon Achievement Test” applied to determine the learning levels of the students and the 72-item “Cornell Conditional Reasoning Test” applied to measure critical-analytic thinking skills. In conclusion, it was revealed that although there was no significant change in critical-analytic thinking skills, the flipped classroom model provided a significant increase in the academic achievement and critical-analytic thinking skills of students from both socio-economic backgrounds

Influence of time and direction information on video head impulse gains

WOS: 000422985600015PubMed ID: 28716764OBJECTIVE: The objective of this study was to establish which factor leads to a higher vestibulo-ocular reflex (VOR) gain: the timing of the movement or the direction of the movement. For this purpose, healthy volunteers were examined under three conditions: (1) when they were informed about the timing of the head movement; (2) when they were informed about the direction of the head movement; and (3) when they knew both the timing and the direction of the head movement. MATERIALS and METHODS: This study included data from 19 participants between the ages of 20 and 23 years with no neurological or vestibular ailments. The gains of the video head impulse test (vHIT) were measured under four different conditions and the final control tests. Five subgroups were defined, and the differences in the subgroups were assessed with using several statistical procedures. RESULTS: We found that there were significant differences between all subgroups gains on the right and left head rotations. Nevertheless, nonsignificant differences were found by performing independent samples t-tests and Mann-Whitney U tests between left and right head rotations for the pairwise comparisons of subgroups. Also, analysis of variance (ANOVA) results indicated that vHIT gains for the right and left, respectively). Thus, knowing the timing or direction or both does not affect vHIT gains. CONCLUSION: The results of these experiments revealed that there is no association whatsoever between VOR gain and awareness of the timing or direction of the movement or both

Impact of lymph node ratio on survival in stage IIIC endometrioid endometrial cancer: a Turkish Gynecologic Oncology Group study

Objective: The purpose of this study was to investigate the prognostic value of lymph node ratio (LNR) in women with stage IIIC endometrioid endometrial cancer (EC). Methods: A multicenter, retrospective department database review was performed to identify patients with stage IIIC pure endometrioid EC at 6 gynecologic oncology centers in Turkey. A total of 207 women were included. LNR, defined as the percentage of positive lymph nodes (LNs) to total nodes recovered, was stratified into 2 groups: LNR1 ( 0.15). Kaplan-Meier method was used to generate survival data. Factors predictive of outcome were analyzed using Cox proportional hazards models. Results: One hundred and one (48.8%) were classified as stage IIIC1 and 106 (51.2%) as stage IIIC2. The median age at diagnosis was 58 (range, 30-82) and the median duration of follow-up was 40 months (range, 1-228 months). There were 167 (80.7%) women with LNR 0.15. The 5-year progression-free survival (PFS) rates for LNR 0.15 were 76.1%, and 58.5%, respectively (p= 0.045). An increased LNR was associated with a decrease in 5-year overall survival (OS) from 87.0% for LNR 0.15 (p= 0.005). LNR > 0.15 was found to be an independent prognostic factor for both PFS (hazard ratio [HR]= 2.05; 95% confidence interval [CI]= 1.07-3.93; p= 0.03) and OS (HR= 3.35; 95% CI= 1.57-7.19; p= 0.002). Conclusion: LNR seems to be an independent prognostic factor for decreased PFS and OS in stage IIIC pure endometrioid EC
