The purpose of this study was to investigate the effects of conceptual change oriented instruction accompanied by demonstrations and gender on tenth grade students̕ understanding of gases concepts, and attitudes toward chemistry. Hundred tenth grade students from two classes taught by the same teacher in a public high school were enrolled in the study in the Fall semester of 2003-2004. Control group students were taught by traditionally designed chemistry instruction (TI), while experimental group students were instructed by conceptual change oriented instruction accompanied by demonstrations (CCID). Gases Concept Test and Attitude Scale toward Chemistry were administered to both groups as a pre-test and post-test to assess the students understanding of gases concepts and students̕ attitudes toward chemistry, respectively. Science Process Skills Test was given at the beginning of the study to determine students̕ science process skills. Learning Style Inventory was also given to all students to determine their learning styles. After treatment, interviews were conducted with the teacher and several students from the two groups. The hypotheses were tested by using analysis of covariance (ANCOVA) and two-way analysis of variance (ANOVA). The results showed that CCID caused significantly better acquisition of the scientific conceptions related to gases than TI. There was no significant effect of the treatment on the students̕ attitudes toward chemistry. No significant effect of gender difference on students̕ understanding the concepts about gases and students̕ attitudes toward chemistry was found. Science process skill was determined as a strong predictor in understanding the concepts related to gases.

The purpose of this study was to investigate the effects of conceptual change text oriented instruction accompanied by demonstrations in small groups (CCTI) on ninth grade students̕ achievement and understanding levels of ecology, attitudes towards biology, and attitudes towards environment. The instruments used in this study were the Test of Ecological Concepts (TEC), the Attitude Scale towards Biology (ASB), the Attitude Scale towards Environment (ASE), and the Test of Logical Thinking (TOLT).

The effect of conceptual change approach on students' understanding of solubility equilibrium concepts
Önder, İsmail; Geban, Ömer; Department of Secondary Science and Mathematics Education (2006)
The main purpose of this study was to compare the effectiveness of instructions one based on conceptual change approach and the other based on traditional chemistry instruction on tenth grade high school students’ understanding of solubility equilibrium concept. In addition, students’ attitudes toward chemistry as a school subject and toward conceptual change texts were investigated. Moreover, students’ science process skills were also investigated. 125 tenth grade students from four classes of a chemistry ...

The main purpose of this study was to investigate the effects of conceptual change oriented instruction accompanied with analogies on eight grade students’ understanding of chemical bonding concepts. In addition, the effect of instruction on students’ attitude toward science as a school subject and the effect of gender difference on understanding of chemical bonding concepts were investigated. Fifty eight-grade students from two classes of a science course taught by the same teacher in Büyükelçi Nazım Belge...
Implementation of conceptual change oriented instruction using hands on activities on tenth grade students' understanding of gases concepts
İpek, İnciser; Kondakçı, Esen; Department of Secondary Science and Mathematics Education (2007)
The purpose of this study was to compare the effectiveness of the conceptual change oriented instruction using hands-on activities and traditionally designed chemistry instruction on 10th grade students’ understanding of gases concept. Also, the effect of instruction on students’ attitude toward chemistry as a school subject was investigated. The sample of the study consisted of 59 tenth grade students from two chemistry classes in a public high school. This study was conducted during the 2006-2007 fall sem...
Statistical tolerancing using designed experiments in a noisy environment
Köksal, Gülser (Elsevier BV, 2003-03-01)
We consider the method of designed experiments for statistical tolerance analysis, and study the impact of experimental error on its results.-It is observed that presence of random error in the experiment environment (e.g. laboratory) could introduce bias in the moment estimators and increases their-respective variances. We propose adjustments to the method that would reduce the bias as well as the variance of these estimators. A numerical example is presented.
