This paper describes the combination of problem-based learning (PBL) and simulation tools in the chemical engineering unit operation laboratory course, focusing on heat transfer concepts using a shell-and-tube heat exchanger experiment. This approach has significantly enhanced student learning outcomes by bridging theory with practice, fostering a…

George-Williams, Stephen R.; Ziebell, Angela L.; Thompson, Christopher D.; Overton, Tina L. – International Journal of Science Education, 2020
Previous work at Monash University has shown that students recognise that inquiry-, problem-, context- and industry-based experiments were better contextualised, more open to decision making and aided in the development of scientific and transferable skills. This study investigated whether these gains persisted over a longer time scale, rather…

Yan, Jianghong; Hu, Shupeng; Xu, Xiudan; Zhao, Dezhang; Wu, Mingjun; Luo, Suxin; Xia, Yong – Biochemistry and Molecular Biology Education, 2018
Medical laboratory technology major was set up to meet rapid development of science and medical research technology in 2013. Students majoring in medical laboratory had learnt a lot of techniques distributed among different specialized courses. But, they did not understand why they had to learn these techniques and how they were applied in a…

The present study employed a quasi-experimental design to assess a computer-based tool, which was intended to scaffold the task of designing experiments when using a virtual lab for the process of experimentation. In particular, we assessed the impact of this tool on primary school students' cognitive processes and inquiry skills before and after…

Riggi, Simone; La Rocca, Paola; Riggi, Francesco – European Journal of Physics, 2011
GEANT4 simulations of the processes affecting the transport and collection of optical photons generated inside a scintillation detector were carried out, with the aim to complement the educational material offered by textbooks to third-year physics undergraduates. Two typical situations were considered: a long scintillator strip with and without a…

Marks, Patrick; Levine, Mindy – Journal of Chemical Education, 2012
Squaraines are a class of organic fluorophores that possess unique photophysical properties, including strong near-infrared absorption and emission. The synthesis of many squaraines involves the condensation of an electron-rich aromatic ring with squaric acid. These reactions are generally refluxed overnight in a benzene-butanol solvent mixture.…

McCall, Richard P. – Physics Teacher, 2012
A recent article in "The Physics Teacher" describes a method for analyzing a systematic error in a Boyle's law laboratory activity. Systematic errors are important to consider in physics labs because they tend to bias the results of measurements. There are numerous laboratory examples and resources that discuss this common source of error.

Prasannakumar, S.; Krishnaveni, S.; Umesh, T. K. – European Journal of Physics, 2012
We report here a simple Compton scattering experiment which may be carried out in graduate and undergraduate laboratories to determine the rest mass energy of the electron. In the present experiment, we have measured the energies of the Compton scattered gamma rays with a NaI(Tl) gamma ray spectrometer coupled to a 1 K multichannel analyzer at…

Kawalec, Tomasz; Bartoszek-Bober, Dobroslawa – European Journal of Physics, 2012
An experimental setup allowing the observation of two-laser interference by the naked eye is described. The key concept is the use of an electronic phase lock between two external cavity diode lasers. The experiment is suitable both for undergraduate and graduate students, mainly in atomic physics laboratories. It gives an opportunity for…

Triana, C. A.; Fajardo, F. – European Journal of Physics, 2012
The aim of this work is to analyse the influence of spring length on the simple harmonic motion of a spring-mass system. In particular, we study the effect of changing the spring length on the elastic constant "[kappa]", the angular frequency "[omega]" and the damping factor "[gamma]" of the oscillations. To characterize the behaviour of these…

Molina, Isabel; Weber, Katrin; Alves Cursino dos Santos, Deborah Y.; Ohlrogge, John – Biochemistry and Molecular Biology Education, 2009
The introduction of dwarfing traits into crops was a major factor in increased grain yields during the "Green Revolution." In most cases those traits were the consequence of altered synthesis or response to the gibberellin (GA) plant hormones. Our current understanding of GA synthesis and physiology has been facilitated by the characterization of…

Roman, Harry T. – Tech Directions, 2011
With some simple metal samples and common household liquids, teachers can build wet cell batteries and use them to teach students about batteries and how they work. In this article, the author offers information that is derived from some simple experiments he conducted in his basement workshop and can easily be applied in the classroom or lab. He…

Schreiber, Alexander M. – Advances in Physiology Education, 2011
A challenging topic in undergraduate physiology courses is the complex interaction between the vertebrate endocrine system and the immune system. There are relatively few established and accessible laboratory exercises available to instructors to help their students gain a working understanding of these interactions. The present laboratory module…
