Turkey has a central educational system in which all of the programs are designed by the Ministry of National Education and distributed to the implementing institutions. As a part of this system, the textbooks written by different writers need to be approved by the commission called Talim Terbiye Kurulu, and these approved books are chosen as…

The present study aimed to investigate the effect of conceptual change texts oriented instruction on 10th grade students' understanding of solubility equilibrium concept. The misconceptions related to solubility equilibrium concept were obtained through interviews with high school chemistry teachers and related literature. The data were obtained…

The purpose of this study was to explore the effects of conceptual change texts oriented instruction on 9th grade students' understanding of chemical bonding concepts. In this study, the main aim of the preparation of conceptual change texts was to activate students' prior knowledge and misconceptions and to help them to understand the chemical…

Metabolism, the sum of all chemical reactions within a living organism, is one of the most fundamental concepts presented in introductory microbiology courses. However, it is often difficult for instructors to effectively translate perfunctory diagrams of glycolysis, the Krebs cycle, and the electron transport chain in a way that is meaningful to…

In high school, many students do not have an opportunity to learn or use statistics. Because statistics is a powerful tool and many students take a statistics class in college, prior exposure to statistics in a chemistry course (or another course) would benefit students. This paper describes some statistical concepts and tests with their…

A three-week laboratory project involving synthesis and characterization of a layered manganese oxide provides an excellent vehicle for teaching important concepts of inorganic chemistry and instrumental methods related to non-molecular systems. Na-birnessite is an easily prepared manganese oxide with a 7 A interlayer spacing and Na[superscript +]…

This study represents the first attempt to elucidate and detail the types of misconceptions high school students hold relating to basic concepts and topics of nuclear chemistry. A diagnostic multiple-choice test was administered to 157 tenth-grade students (15-16 years old) and the data were analyzed. The results show that high school students…

The general chemistry course at Harvey Mudd College presents chemical principles and addresses technology's impact on society. Students consider environmental and economic implications of chemical scenarios in real-world case studies created for team-based analysis and discussion. Case study design, implementation, and assessment are presented.…

This study focused on students' misconceptions related to evaporation, evaporation rate, and vapour pressure. Open-ended diagnostic questions were used with 107 undergraduates in the Primary Science Teacher Training Department in a state university in Turkey. In addition, 14 students from that sample were interviewed to clarify their written…

A problem solving strategy, Thinking Aloud Pair Problem Solving (TAPPS), developed by Arthur Whimbey to help students monitor and understand their own thought process is presented. The TAPPS strategy encouraged the students interact verbally with each other to solve chemistry problems and improve the achievements in chemistry.

The reading, analyzing and critiquing of primary literature in both writing and oral forms are daunting tasks for science undergraduates. These activities are recognized as skills that science undergraduates should develop in order to improve their scientific communication abilities.

A previous study showed that elementary teaching majors enrolled in an inquiry-based physical science course developed chemistry content knowledge comparable to that of students enrolled in traditional lecture-based courses. This current study compares the views of these elementary teaching majors regarding how chemistry is taught and learned to…

The National Science Education Standards (NRC 1996) recognize the efficacy of teaching science within the context of history, emphasizing the evolution of concepts, models, and theories. By studying science in a historical context, students view themselves less as spectators and more as participants in this human quest for truth and understanding.…

The present study was conducted to investigate the degree of effectiveness of cooperative learning instruction over a traditional approach on 11th grade students' understanding of electrochemistry. The study involved forty-one 11th grade students from two science classes with the same teacher. To determine students' misconceptions concerning…

"The Geography Teacher" provides hands-on reference and educative material for K-12 Geography teachers. The journal also pioneers innovative ideas for contemporary teaching methods, including lesson plans. This issue contains the following: (1) Ask Dr. de Blij (Dr. Harm de Blij); (2) Improving Geographic Understanding with a State Atlas…
