Students' understanding of matter: The effect of reasoning ability and grade level

Şahin, Elvan
This study aims at investigating the effect of grade level on students' achievement in matter concept and reasoning abilities, when their test anxiety was controlled. The data was collected from 8th, 10th and 11th grade students by the administration of The Matter Concept Test, Test of Logical Thinking, and the Motivated Strategies for Learning Questionnaire. The results revealed that there was a significant effect of grade level on students' achievement in favor of 11th grade students and the linear combination of reasoning abilities was significantly related to students' achievement. In the Matter Concept Test, the 10th graders did better than 8th graders and the 11th graders did better than either. The only exception to this general observation was the 8th graders' better performance on a small number of questions, which related to topics that were taught and nationally examined in the 8th grade. It seems likely, therefore, that the more chemistry a student is taught the better he/she is likely to be, except that if a topic is examined while it is reasonably fresh in a student's mind the results are likely to be better than if the test is carried out 2-3 years later. © The Royal Society of Chemistry.

Eighth grade students' emotion regulation strategies during test taking: the role of gender, cognitive appraisal processes, academic self-efficacy, and test anxiety
Güçlü, Ayşegül; Çapa Aydın, Yeşim; Department of Educational Sciences (2009)
The purpose of the study was to examine the role of test anxiety, academic self-efficacy, and cognitive appraisal processes in predicting eighth grade students’ emotion regulation strategies during test taking. In addition, gender was included as a predictor in the study. The sample of the study consisted of 778 eighth grade students (398 females and 380 males) in 17 schools of Çankaya and Yenimahalle districts in Ankara. Emotion Regulation during Test Taking Scale (ERT) (Schutz, Distefano, Benson, & Davis,...
Self efficacy and previous testing experiences as predictors of test anxiety among college students
Çapa Aydın, Yeşim (null; 2002-10-19)
This study examined how college students' test anxiety related to previous testing experiences and self-efficacy. Participants were 29 undergraduate college students enrolled at a Midwestern university. Instruments used to measure the criterion and predictor variables were: Test Anxiety Scale, College Academic Self-efficacy Scale, Generalized Self-Efficacy Scale, and Previous Testing Experience Scale. Two separate simultaneous multiple regression analyses were performed to answer the research questions. Res...

ÖZÜDOĞRU, MELİKE; Aksu, Meral (Australasian Society for Computers in Learning in Tertiary Education, 2020-01-01)
The aim of this study was to investigate whether flipped learning affects pre-service teachers' achievement and perceptions related to the classroom environment. This experimental study was conducted in the fall semester of 2017-2018 for 11 weeks at a state university in Turkey and included a total of 56 pre-service teachers. An achievement test and a scale were implemented to collect the data. The analyses through descriptive and inferential statistical analysis techniques showed that flipped learning grou...
