Elia Bergamin; Giacomo Fabris; Matteo Neffat; Paola Baron Toaldo; Daniela De Luchi; Renato Bonomi – Journal of Chemical Education, 2023
A class of 18 students attending the last year of an Italian high school was divided into groups and performed the extraction of pigments contained in hibiscus tea. Each group worked at a different temperature and carried out multiple extractions using distilled water as a solvent. By means of UV-vis spectroscopy it was possible to determine the…

Mistry, Nimesh; Gorman, Stephen G. – Chemistry Education Research and Practice, 2020
To be able to design a laboratory course it is important to know what laboratory skills students possess before the course starts. This way the course can focus on developing skills in areas that are lacking. Despite the extensive literature on laboratory education, there are few studies on what laboratory skills students have at this stage of…

Parreira, Pedro; Yao, Eric – Physics Education, 2018
Being able to contextualise and solve complex problems is a highly valued skill in STEM graduates--a skill which we strive to nurture in our students. Since its introduction into undergraduate teaching, laboratory teaching has been used to consolidate students conceptual understanding, develop their practical skills and inculcate an evidence based…

Mageswary Karpudewan; Noor Haslina Daman Huri – Journal of Chemical Education, 2023
Transforming the chemistry curriculum to an interdisciplinary perspective is essential for preparing students to meet interdisciplinary career demands and to brace themselves for the challenges of complex environmental and health issues. The study introduces four interdisciplinary electrochemistry STEM-lab activities as an alternative to the…

Barrera, Luis A.; Alma C. Escobosa; Alsaihati, Laila S.; Noveron, Juan C. – Journal of Chemical Education, 2019
Herein we present a modified iodine clock experiment which replaces starch with cellulose paper. This provides the reaction with a white solid surface in which color change can be clearly observed and reduces reagent amounts required to 540 µL per group. After data acquisition, students are required to calculate reaction orders and the reaction…

Calalb, Mihail – Athens Journal of Education, 2023
A detailed characteristic of teaching and learning approaches used within the new concept of Learning by Being (LBB) is given. The evolution of educational paradigms from Learning by Doing (LBD) and Learning by Understanding (LBU) toward LBB is analyzed. The basic idea of LBB is students' ownership on cognitive goals, or the assumption of learning…

McCormick, Sierra; Powers, Jacklyn; Davenport, Jodi; Yaron, David – Grantee Submission, 2021
In today's science classrooms, with the integration of the Next Generation Science Standards (NGSS), teachers are encouraged to guide instruction through real-world phenomena and promote critical thinking through inquiry-based learning that helps students learn the reasoning and practical skills of scientists, rather than just rote memorization of…

Chuasontia, Itsarapong; Sirirat, Tanita – Physics Education, 2021
This research aimed to design an instructional module to teach light diffraction by a grating to secondary students applying a science, technology, engineering, and mathematics (STEM)-integrated approach. Based on this approach, instructional management integrated the disciplines of physics and mathematics with engineering design process…

Bicak, Besim Enes; Borchert, Cornelia Eleonore; Höner, Kerstin – Education Sciences, 2021
Developing scientific reasoning (SR) is a central goal of science-teacher education worldwide. On a fine-grained level, SR competency can be subdivided into at least six skills: "formulating research questions," "generating hypotheses," "planning experiments," "observing and measuring," "preparing data…

Thompson, Gregory Louis – ProQuest LLC, 2019
This study examined laboratory experiments and traditional lecturing as an introductory teaching method in physics. In this participatory action research study, a qualitative and quantitative method were used to examine the level of achievement and the levels of engagement of high school students in introductory physics. The qualitative data was…

Perera, Alokya P.; Bopegedera, A. M. R. P. – Journal of Chemical Education, 2014
The increase in ocean acidity since preindustrial times may have deleterious consequences for marine organisms, particularly those with calcareous structures. We present a laboratory experiment to investigate this impact with general, introductory, environmental, and nonmajors chemistry students. For simplicity and homogeneity, calcite was…

Davenport, Jodi L.; Rafferty, Anna N.; Yaron, David J. – Journal of Chemical Education, 2018
How can we help students develop an understanding of chemistry that integrates conceptual knowledge with the experimental and computational procedures needed to apply chemistry in authentic contexts? The current work describes ChemVLab+, a set of online chemistry activities that were developed using promising design principles from chemistry…

Hayes, David; Widanski, Bozena – Journal of Chemical Education, 2013
A laboratory experiment is described that introduces students to "real-world" hazardous waste management issues chemists face. The students are required to define an analytical problem, choose a laboratory analysis method, investigate cost factors, consider quality-control issues, interpret the meaning of results, and provide management…
