Hosker, Bill S. – Journal of Chemical Education, 2018
A highly simplified variation on the do-it-yourself spectrophotometer using a smartphone's light sensor as a detector and an app to calculate and display absorbance values was constructed and tested. This simple version requires no need for electronic components or postmeasurement spectral analysis. Calibration graphs constructed from two…

Ramnarain, Umesh; Padayachee, Keshni – South African Journal of Education, 2015
This study reports on the analysis of South African Life Sciences and Biology textbooks for the inclusion of the nature of science using a conceptual framework developed by Chiappetta, Fillman and Sethna (1991). In particular, we investigated the differences between the representation of the nature of science in Biology textbooks that were written…

C¸etin, Pinar Seda; Eymur, Gülüzar – Journal of Chemical Education, 2017
In this study, we employed a new instructional model that helps students develop scientific writing and presentation skills. Argument-driven inquiry (ADI) is one of the most novel instructional models that emphasizes the role of argumentation and inquiry in science education equally. This is an exploratory study where five ADI lab activities take…

Dudu, Washington T. – South African Journal of Education, 2014
The paper explores conceptions of the nature of scientific inquiry (NOSI) held by five teachers who were purposively and conveniently sampled. Teachers' conceptions of the NOSI were determined using a Probes questionnaire. To confirm teachers' responses, a semi-structured interview was conducted with each teacher. The Probes questionnaire was…

Lu, Shanshan; Bi, Hualin; Liu, Xiufeng – International Journal of Science Education, 2018
The study that is the subject of this paper tested the effects of EDI (explanation-driven inquiry) on students' redox conceptual understanding and their misconceptions. Two classes of 119 10th grade high school students were involved. Two groups of students in the same school were chosen. One class that was taught by EDI teaching was set as the…

Carraher, Jack M.; Curry, Sarah M.; Tessonnier, Jean-Philippe – Journal of Chemical Education, 2016
Teaching complex chemistry concepts such as kinetics using inquiry-based learning techniques can be challenging in a high school classroom setting. Access to expensive laboratory equipment such as spectrometers is typically limited and most reaction kinetics experiments have been designed for advanced placement (AP) or first-year undergraduate…

McLaughlin, Cheryl A.; Broo, Jennifer; MacFadden, Bruce J.; Moran, Sean – Journal of Biological Education, 2016
One major emphasis of reform initiatives in science education is the importance of extended inquiry experiences for students through authentic collaborations with scientists. As such, unique partnerships have started to emerge between science and education in an ongoing effort to capture the interest and imaginations of students as they make sense…

Kakisako, Mami; Nishikawa, Kazuyuki; Nakano, Masayoshi; Harada, Kana S.; Tatsuoka, Tomoyuki; Koga, Nobuyoshi – Journal of Chemical Education, 2016
This study focuses on the design of a learning program to introduce complexometric titration as a method for determining water hardness in a high school chemistry laboratory. Students are introduced to the different properties and reactions of hard water in a stepwise manner so that they gain the necessary chemical knowledge and conceptual…

Moraes, Edgar P.; Confessor, Mario R.; Gasparotto, Luiz H. S. – Journal of Chemical Education, 2015
This article proposes an indirect method to evaluate the corrosion rate of iron nail in simulated seawater. The official procedure is based on the direct measurement of the specimen's weight loss over time; however, a highly precise scale is required and such equipment may not be easily available. On the other hand, mobile phones equipped with…

Erk, Kendra A.; Rhein, Morgan; Krafcik, Matthew J.; Ydstie, Sophie – Journal of Chemical Education, 2015
An educational activity is described in which the structure and physical properties of disposable plastic cups were directly related to the method of processing. The mechanical properties of specimens cut from the walls of poly(ethylene terephthalate) (PETE) cups, oriented parallel and perpendicular to the thermoforming direction, were measured in…

Journal of Chemical Education, 2015
This paper presents the design and practical application of a laboratory inquiry at high school chemistry level for systematic chemistry learning, as exemplified by a thermochemical approach to the reaction stoichiometry of neutralization using Job's method of continuous variation. In the laboratory inquiry, students are requested to propose the…

Dukerich, Larry – Journal of Chemical Education, 2015
With the release of the Next Generation Science Standards, high school chemistry teachers are now pondering the implications of their recommendations for their teaching. They may agree that traditional instruction, as the Framework points out, "emphasizes discrete facts with a focus on breadth over depth, and does not provide students with…
