Hunter, Rebecca A. – Journal of Chemical Education, 2021
An important objective of any analytical chemistry course is for students to generate and interpret data from the analysis of complex, real-world samples in order to assess the effectiveness of the analysis method, including the calibration. In this laboratory exercise, students directly compare calibration methods (external standards and standard…

Nartey, Esther; Hanson, Ruby – Science Education International, 2021
The purpose of the study was to determine the perceptions that senior high school (SHS) chemistry students, and teachers have about organic chemistry as well as to compare organic chemistry topics that are difficult for students and teachers. Simple random sampling (lottery) and purposive sampling methods were used to select a sample of 100 SHS…

Wiyarsi, Antuni; Pratomo, Heru; Priyambodo, Erfan – Journal of Turkish Science Education, 2020
The study aims to investigate the effect of context-based learning (CBL) on vocational high school students' chemical literacy of petroleum topics. Through quasi-experimental research with pretest-posttest design, 30 students from the automotive engineering program were assigned as the experimental group, while 31 students from the same school…

Tanino, Yukie; Syed, Amer – Education Sciences, 2019
We designed a hands-on laboratory exercise to demonstrate why injecting an aqueous polymer solution into an oil reservoir (commonly known as "polymer flooding") enhances oil production. Students are split into three groups of two to three. Each group is assigned to a packed Hele-Shaw cell pre-saturated with oil, our laboratory model of…

d'Alessio, Matthew A.; Schwartz, Joshua J.; Pedone, Vicki; Pavia, Jenni; Fleck, Jenna; Lundquist, Loraine – Journal of Geoscience Education, 2019
Promoting collaboration and discourse in asynchronous online courses is challenging; students need something engaging to talk about, a communications medium in which to fluidly discuss it, and a social environment that supports discourse. We designed a fully online introductory geoscience lecture and lab course called Geology Goes Hollywood that…

Chao, Jie; Chiu, Jennifer L.; DeJaegher, Crystal J.; Pan, Edward A. – Journal of Science Education and Technology, 2016
Deep learning of science involves integration of existing knowledge and normative science concepts. Past research demonstrates that combining physical and virtual labs sequentially or side by side can take advantage of the unique affordances each provides for helping students learn science concepts. However, providing simultaneously connected…

Cheong, Irene Poh-Ai; Johari, Marliza; Said, Hardimah; Treagust, David F. – International Journal of Science Education, 2015
The need for renewable and non-fossil fuels is now recognised by nations throughout the world. Consequently, an understanding of alternative energy is needed both in schools and in everyday life-long learning situations. This study developed a two-tier instrument to diagnose students' understanding and alternative conceptions about alternative…

Samon, Sigal; Levy, Sharona T. – Science Education, 2017
The study explores how a complexity approach empowers science learning. A complexity approach represents systems as many interacting entities. The construct of micro-macro compatibility is introduced, the degree of similarity between behaviors at the micro- and macro-levels of the system. Seventh-grade students' learning about gases was studied…

The SUN approach to biological energy transfer education is fundamentally different from past practices that trace chemical and energy inputs and outputs. The SUN approach uses a hydrogen fuel cell to convince learners that electrons can move from one substance to another based on differential attraction. With a hydrogen fuel cell, learners can…

Yalçinkaya, Eylem; Boz, Yezdan – Chemistry Education Research and Practice, 2015
The main purpose of the present study was to investigate the effect of case-based instruction on remedying 10th grade students' alternative conceptions related to gas concepts. 128 tenth grade students from two high schools participated in this study. In each school, one of the classes was randomly assigned as the experimental group and the other…

Oliver-Hoyo, Maria T.; Pinto, Gabriel – Journal of Chemical Education, 2008
This instructional resource utilizes consumer product information by which students compare theoretical stoichiometric calculations to CO[subscript 2] car emissions and fuel consumption data. Representing graphically the emission of CO[subscript 2] versus consumption of fuel provides a tangible way of connecting concepts studied in chemistry…
