This study investigates the effects of the Science Writing Heuristic (SWH), known as an argumentation-based science inquiry approach, on Grade 9 students' performance on a post-test in relation to their academic achievement levels. Four intact classes taught by 2 chemistry teachers from a Turkish public high school were selected for the study; one class from each teacher was assigned as the treatment group, and the other class from each teacher was assigned as the control group. Students in the treatment group were instructed using the SWH approach while those in the control group were instructed using traditional instruction. Students' achievement levels were determined based on their chemistry mean scores for the previous semester, which were used to determine the impact of the treatment on varying levels of achievement. A test measuring students' achievement in chemical change and mixture was administered as pre- and post-test for both groups. The data were analyzed by using Analysis of Covariance (ANCOVA). The findings indicate that the SWH approach contributed to students' test performances significantly better than the traditional approach. Student performance on the post-test differed with respect to their academic achievement levels significantly. Low achievers and middle achievers in the SWH group significantly outperformed those in the traditional group on the post-test.

Tucel, Tuğçe; Çakıroğlu, Jale; Öztekin, Ceren (2015-09-04)
The purpose of this study was to explore the effects of Science Writing Heuristic (SWH) approach on middle school students' metacognition. For this purpose, a quasi-experimental research design, the non-equivalent control group post-test only design was used with the aim to compare the experimental and the comparison groups mean difference with respect to dependent variables. 60 eight grade students with a mean age of 14 years in two classes selected from one public school in an urban area. One class was ra...
The Effect of Logical Thinking Ability and Gender on Science Achievements and Attitudes towards Science
SADİ, ÖZLEM; Çakıroğlu, Jale (2015-01-01)
The aim of this study was to investigate the effect of logical thinking ability and gender on students' science achievements and attitudes towards science. Test of Logical Thinking (TOLT), Attitude towards Science Scale, and Sense Organs Achievement Test were administered to 72 elementary school students to determine their logical thinking abilities, attitudes towards science and achievement, respectively. The two-way Multivariate Analysis of Variance (MANOVA) results revealed no statistically significant m...
How do pre-service science teachers perceive local and non-local environmental problems?
Tuncay, Büşra; Yılmaz Tüzün, Özgül (null; 2011-04-03)
The study aimed to investigate how pre-service science teachers perceived local and non-local environmental problems and whether there were any differences in their perceptions. A convenience sample of 114 pre-service science teachers participated to the study. For data collection four local and four non-local environmental cases about deforestation, e-waste, oil spill, and global warming environmental problems were prepared by the researchers and ten questions about the certainty, tangibility, and seri...
Prospective mathematics teachers' critical thinking processes about scientific research: Newspaper article example
Kus, Mehtap; Çakıroğlu, Erdinç (2020-01-01)
This study aimed to explore how prospective middle school mathematics teachers think critically about a newspaper article that reported the findings of a statistical research. Participants of the study were four fourth-year students enrolled at the mathematics teacher education program of a public university. To investigate the research question of the study, case study method was employed. Indepth semi-structured interviews were done to examine participants' critical thinking processes. The findings of the...
Making sense of statistical and probabilistic information in the media texts Pre service teachers critical thinking processes
ÖZEN, MEHTAP; Çakıroğlu, Erdinç (2015-02-08)
This study aimed to investigate the critical thinking processes that pre-service middle school mathematics teachers utilize when they intensely engaged with the media text based on statistical and probabilistic information. Data were collected through in-depth interviews with four pre-service middle school mathematics teachers in a public university. The findings of the study pointed out that pre-service middle school mathematics teachers progressed through different critical thinking processes, including c...
