Galloway, Kelli R.; Bretz, Stacey Lowery – Chemistry Education Research and Practice, 2016
A series of quantitative studies investigated undergraduate students' perceptions of their cognitive and affective learning in the undergraduate chemistry laboratory. To explore these quantitative findings, a qualitative research protocol was developed to characterize student learning in the undergraduate chemistry laboratory. Students (N = 13)…

Bain, Ryan M.; Pulliam, Christopher J.; Yan, Xin; Moore, Kassandra F.; Mu¨ller, Thomas; Cooks, R. Graham – Journal of Chemical Education, 2014
Undergraduate laboratories generally teach an understanding of chemical reactivity using bulk or semimicroscale experiments with product isolation and subsequent chemical and spectroscopic analysis. In this study students were exposed to mass spectrometry as a means of chemical synthesis as well as analysis. The ionization method used, paper…

DeKorver, Brittland K.; Towns, Marcy H. – Journal of Chemical Education, 2015
Little research exists on college students' learning goals in chemistry, let alone specifically pertaining to laboratory coursework. Because students' learning goals are linked to achievement and dependent on context, research on students' goals in the laboratory context may lead to better understanding about the efficacy of lab curricula. This…

Eshach, Haim; Kukliansky, Ida – International Journal of Science and Mathematics Education, 2018
The present study uses the intuitive rules theory as a framework to examine whether some of the difficulties in dealing with errors and uncertainties observed among students in the university physics laboratory can stem from their use of intuitive rules. The study also examines the relationship between the use of intuitive rules and laboratory…

Girault, Isabelle; d'Ham, Cedric; Ney, Muriel; Sanchez, Eric; Wajeman, Claire – International Journal of Science Education, 2012
Many studies have stressed students' lack of understanding of experiments in laboratories. Some researchers suggest that if students design all or parts of entire experiment, as part of an inquiry-based approach, it would overcome certain difficulties. It requires that a procedure be written for experimental design. The aim of this paper is to…

DeKorver, Brittland K.; Towns, Marcy H. – Journal of Research in Science Teaching, 2016
Efforts to reform undergraduate chemistry laboratory coursework typically focus on the curricula of introductory-level courses, while upper-level courses are bypassed. This study used video-stimulated recall to interview 17 junior- and senior- level chemistry majors after they carried out an experiment as part of a laboratory course. It is assumed…

Kimaru, Irene; Koether, Marina; Chichester, Kimberly; Eaton, Lafayette – Journal of Chemical Education, 2017
Analytical method transfer (AMT) and dissolution testing are important topics required in industry that should be taught in analytical chemistry courses. Undergraduate students in senior level analytical chemistry laboratory courses at Kennesaw State University (KSU) and St. John Fisher College (SJFC) participated in development, validation, and…

Bain, Ryan M.; Pulliam, Christopher J.; Raab, Shannon A.; Cooks, R. Graham – Journal of Chemical Education, 2015
In this laboratory experiment, students learn how to use ESI to accelerate chemical synthesis and to couple it with on-line mass spectrometry for structural analysis. The Hantzsch synthesis of symmetric 1,4-dihydropyridines is a classic example of a one-pot reaction in which multiple intermediates can serve to indicate the progress of the reaction…

Coker, Jeffrey Scott – Journal of College Science Teaching, 2017
Despite numerous calls for science education to be driven by authentic investigation, many laboratory experiences continue to consist of disconnected weekly units during which students carry out instructions that lead to some predetermined finding. This study developed and evaluated a pedagogical design for introductory biology labs where students…

Wei, Bing; Li, Xiaoxiao – International Journal of Science Education, 2017
It is commonly recognised that practical work has a distinctive and central role in science teaching and learning. Although a large number of studies have addressed the definitions, typologies, and purposes of practical work, few have consulted practicing science teachers. This study explored science teachers' perceptions of experimentation for…

Kadayifci, Hakki; Yalcin-Celik, Ayse – Science Education International, 2016
This study examined the effectiveness of Argument-Driven Inquiry (ADI) as an instructional model in a general chemistry laboratory course. The study was conducted over the course of ten experimental sessions with 125 pre-service science teachers. The participants' level of reflective thinking about the ADI activities, changes in their science…

Song, Donggil; Karimi, Arafeh; Kim, Paul – Interactive Learning Environments, 2016
Teaching argumentation with appropriate activities and strategies would support a wide range of goals in science education. Though science labs have been suggested and employed for argumentation activities, such educational expenditures are likely to be beyond the means of most schools in under-resourced areas. Due to the lack of appropriate…

Supasorn, Saksri – Chemistry Education Research and Practice, 2015
This study aimed to develop the small-scale experiments involving electrochemistry and the galvanic cell model kit featuring the sub-microscopic level. The small-scale experiments in conjunction with the model kit were implemented based on the 5E inquiry learning approach to enhance students' conceptual understanding of electrochemistry. The…

Zwickl, Benjamin M.; Hirokawa, Takako; Finkelstein, Noah; Lewandowski, H. J. – Physical Review Special Topics - Physics Education Research, 2014
In response to national calls to better align physics laboratory courses with the way physicists engage in research, we have developed an epistemology and expectations survey to assess how students perceive the nature of physics experiments in the contexts of laboratory courses and the professional research laboratory. The Colorado Learning…

Ozmen, Haluk; Demircioglu, Gokhan; Burhan, Yasemin; Naseriazar, Akbar; Demircioglu, Hulya – Asia-Pacific Forum on Science Learning and Teaching, 2012
The aim of this study is to examine the effectiveness of an intervention based on a series of laboratory activities enhanced with concept cartoons. The purpose of the intervention was to enhance students' understanding of acid-base chemistry for eight grade students' from two classes in a Turkish primary school. A pretest-posttest non-equivalent…
