Baran, Mukadder – Journal of Education and Training Studies, 2016
The purpose of this study was to investigate not only the applicability of the method of Problem-Based Learning (PBL) to the lesson subject of "Gasses" within the scope of the 9th grade course of Chemistry in Hakkari Gazi High School but also the influence of this method on the students' achievement levels in chemistry and on their…

Karaduman, Betül; Doganay, Ahmet; Uçar, Sedat – International Journal of Research in Education and Science, 2021
Didactic transposition theory examines the development from scientific/academic knowledge being produced by scientists to it becoming learned knowledge constructed by learners. According to the theory, four kinds of knowledge exist: scientific knowledge, knowledge to be taught, taught knowledge and learned knowledge. In this study, learning and…

Çilek, Elif – Journal of Inquiry Based Activities, 2019
This study aimed to plan and implement a lesson that focuses on the role of gases that are effective in global warming and to increase the middle school students' awareness about global warming. The case study method was used. First, a Science, Technology, Engineering, Mathematics (STEM) lesson that focused on the increased use of fossil-based…

Hayez, Bernard – Journal of Chemical Education, 2018
From a physical point of view, the "partial pressure" of a component "i" in a gas mixture is defined as the contribution of molecules "i" to the force per unit area that the molecules of the mixture exert on the wall. The relation pi = x[subscript i]P (where x[subscript i] is the mole fraction of "i" and…

Kraftmakher, Yaakov – Physics Education, 2013
Electron-atom collisions in gases are an aspect of atomic physics. Three experiments in this field employing a thyratron are described: (i) the Ramsauer-Townsend effect, (ii) the excitation and ionization potentials of xenon and (iii) the ion-electron recombination after interrupting the electric discharge.

Molek, Karen Sinclair; Reyes, Karl A.; Burnette, Brandon A.; Stepherson, Jacob R. – Journal of Chemical Education, 2015
Measuring the heat capacity ratios, [gamma], of gases either through adiabatic expansion or sound velocity is a well established physical chemistry experiment. The most accurate experiments depend on an exact determination of sound origin, which necessitates the use of lasers or a wave generator, where time zero is based on an electrical trigger.…

Varberg, Thomas D.; Pearlman, Bradley W.; Wyse, Ian A.; Gleason, Samuel P.; Kellett, Dalir H. P.; Moffett, Kenneth L. – Journal of Chemical Education, 2017
In this paper, we describe an experiment for the undergraduate physical chemistry laboratory in which students determine the speed of sound in the gases He, N[subscript 2], CO[subscript 2], and CF[subscript 3]CH[subscript 2]F. The experimental apparatus consists of a closed acrylic tube containing the gas under study. White audio noise is injected…

Mete, Pelin – Science Education International, 2020
For abstract concepts to be well understood, students need to be familiar with the concepts and able to associate them correctly. Students cannot make scientific explanations on the subject unless they can establish relationships. This study aimed to determine the understanding level of 11th-grade high school students on "gases" in terms…

Bruce, Mitchell R. M.; Wilson, Tiffany A.; Bruce, Alice E.; Bessey, S. Max; Flood, Virginia J. – Journal of Chemical Education, 2016
In this experiment, students build a spectrometer to explore infrared radiation and greenhouse gases in an inquiry-based investigation to introduce climate science in a general chemistry lab course. The lab is based on the exploration of the thermal effects of molecular absorption of infrared radiation by greenhouse and non-greenhouse gases. A…

Erceg, Nataša; Aviani, Ivica; Mešic, Vanes; Gluncic, Matko; Žauhar, Gordana – Physical Review Physics Education Research, 2016
In this study, we investigated students' understanding of concepts related to the microscopic model of gas. We thoroughly reviewed the relevant literature and conducted think alouds with students by asking them to answer open-ended questions about the kinetic molecular theory of gases. Thereafter, we transformed the open-ended questions into…

Álvarez-Rúa, Carmen; Borge, Javier – Journal of Chemical Education, 2016
Thermodynamic processes are complex phenomena that can be understood as a set of successive stages. When treating processes, classical thermodynamics (and most particularly, the Gibbsian formulation, predominantly used in chemistry) only pays attention to initial and final states. However, reintroducing the notion of process is absolutely…

Zorrilla, David; Sánchez-Márquez, Jesús; García, Víctor; Fernández, Manuel – Journal of Chemical Education, 2019
Teaching and understanding the concepts related to ideal gases and their transformations is relatively uncomplicated. However, for science and engineering students, reaching an understanding of and assimilating the concepts related to real gases and their transformations is a more difficult goal. Backed by their considerable experience teaching…

Ayyildiz, Yildizay; Tarhan, Leman – Chemistry Education Research and Practice, 2013
This study aims at investigating the effects of case studies developed by the researchers on Science Teaching students' understanding of "gases, liquids and solids," and their attitudes towards chemistry lessons. The study was conducted on 52 freshmen from the Department of Science Teaching at a university in Turkey. Pre-test and…

Davies, Gary B. – Physics Education, 2017
Carrying out classroom experiments that demonstrate Boyle's law and Gay-Lussac's law can be challenging. Even if we are able to conduct classroom experiments using pressure gauges and syringes, the results of these experiments do little to illuminate the kinetic theory of gases. However, molecular dynamics simulations that run on computers allow…
