Contribution of the argumentation-based laboratory to pre-service chemistry teachers’ microscopic explanations of chemistry concepts

2017-04-25
The purpose of this study was to investigate the impact of argumentation-based chemistry laboratory on pre-service chemistry teachers’ (PCT) explanations of chemistry concepts at micro level. A total of 12 PCTs (5 males and 7 females) participated in the Saturday, April 22, 2017 NARST 2017 Annual International Conference Abstracts 18 | N A R S T A B S T R A C T S study. Data were collected using Chemistry Concepts Test, essay type questions, and semi-structured interviews. Chemistry Concept Test, which included 24 multiple choice items, was administered as a pre-test to determine pre-existing knowledge of PCTs at the beginning of the semester. The items in the test consisted of high school (grade level 9-12) chemistry concepts such as acid-bases, gases, and reaction rate etc. Results showed that, the mean of the argumentation based laboratory (ABL) group (12.3) was greater than the mean of the traditional laboratory group (TL) (10.0). 60% of the participants in ABL group provided correct explanation at microscopic level (3 points) whereas this percentage for TL group was 40%. In addition, there were three participants possessing incorrect knowledge (0 point) in TL group; however, there was no 0 point in ABL group.

Effect of analogy-enhanced instruction accomponied with concept maps on understanding of acid- base concept
Yılmazoğlu, Candan; Yılmazoğlu, Candan; Department of Secondary Science and Mathematics Education (2004)
This study was conducted to explore the effectiveness of analogy-enhanced instruction accompanied with concept maps over traditionally designed chemistry introduction on understanding of acid-base concept and attitude toward chemistry as a school subject. 81 8th grade students from two classes of a chemistry course taught by the same teacher in Nuh Eskiyapan Primary School in Ankara in 2003-2004 fall semesters were enrolled in the study. There were two groups of students. During the treatment, students in t...
The Effect of cooperative learning based on conceptual change approach on students’ understanding of chemical bonding concepts
Eymur, Gülüzar; Geban, Ömer; Department of Secondary Science and Mathematics Education (2014)
The main purpose of this study was to investigate the effects of cooperative learning based on conceptual change approach on 9th grade students’ understanding in chemical bonding concepts and their attitudes toward chemistry as a school subject compared to traditionally designed chemistry instruction. Seventy-two ninth grade students from two intact classes of chemistry course taught by same teacher in a public high school in Ankara were participated. The study was applied in the spring semester of 2011-201...
Examination of the topic-specific nature of pedagogical content knowledge in teaching electrochemical cells and nuclear reactions
Aydın, Sevgi; Friedrichsen, Patricia M.; Boz, Yezdan; Hanuscin, Deborah L. (Royal Society of Chemistry (RSC), 2014-01-01)
The purpose of this study was to examine experienced chemistry teachers' pedagogical content knowledge (PCK) for two different topics in chemistry to better understand how PCK is specific to topic, including whether all components of PCK are topic-specific and to what degree. To explore the topic-specific nature of PCK, we examined two experienced teachers' PCK using a case study methodology. Multiple data collection strategies were used, including a card-sorting activity, Content Representation (CoRe), sem...
Effectiveness of constructivist approach on students' understanding of chemical bonding concepts
Uzuntiryaki, Esen; Geban, Ömer; Department of Secondary Science and Mathematics Education (2003)
The main purpose of this study was to compare the effectiveness of instruction based on constructivist approach over traditionally designed chemistry instruction on ninth grade students2 understanding of chemical bonding concepts. In addition, the effect of instruction on students2 attitude toward chemistry as a school subject and the effect of gender difference on understanding of chemical bonding concepts were investigated. Forty-two ninth grade students from two classes of a chemistry course taught by th...
Effect of instruction using conceptual change strategies on students' conceptions of chemical reactions and energy
Ceylan, Eren; Geban, Ömer; Department of Secondary Science and Mathematics Education (2004)
The main purpose of the study was to compare the effectiveness of the conceptual change oriented instruction through demonstration and traditionally designed chemistry instruction on 10th grade students̕ understanding of chemical reactions and energy concepts and attitudes towards chemistry as a school subject. In this study, 61 tenth grade students from two classes of chemistry course instructed by same teacher from Atatürk Anatolian High School took part. The study was conducted during 2003-2004 fall seme...
