“…Parker, de los Santos and Anderson (2015) describe how students' challenges with tracing matter and energy through carbon-transforming processes may impede student understanding of biofuels since these difficult concepts are at the center of analyses of the performance of biofuels. Other science education literature has described techniques for using biofuel technology in a laboratory setting (Blatti & Burkart, 2012;El Seoud, Loffredo, Galgano, Sato, & Reichardt, 2011;Wagner, Koehle, Moyle, & Lambert, 2010). Themes emerging from students' positions on biofuels may reveal gaps in understanding about scientific, social, and economic dimensions of the issue.…”

We propose two contrasting types of student decision-making based on social and cognitive psychology models of separate mental processes for problem solving. Informal decision-making uses intuitive reasoning and is subject to cognitive biases, whereas formal decision-making uses effortful, logical reasoning. We explored indicators of students' formal decision-making in a socioscientific issue-focused general science post-secondary course that used a seven-step decision-making framework based in decision-science models. We found that students' value orientations predicted students' stance towards biofuels at the beginning but not at the end of the course, indicating some students' post-survey opinions were less rooted in affective value-judgments. Themes in student personal reasoning about biofuels were primarily focused on environmental and economic dimensions of the issue and revealed a greater awareness of alternative options and potential consequences of biofuel use at the end of the course. We observed a decrease in students' emotive arguments and an increase in students' justificatory arguments about biofuel use. A formal decision-making framework may be a useful tool in supporting students' formal, reasoned approach to deciding what we should do about complex socioscientific issues.

“…Most of the papers propose experiments using a Brazilian context or topic, for instance, focusing on biomass or biofuels [44,45], as is the case of the quantitative analysis of bioethanol and its blends with gasoline by using solvatochromic dyes [46]. The students have tested two approaches: (i) use of a solvatochromic dye, followed by determination of fuel composition from plots of the empirical fuel polarity vs. its composition; (ii) use of an ethanol-soluble dye, followed by determination of the blend composition from a Beer's law plot; the former proved to be much more convenient.…”

“…(Brooks and Brooks, 1995) Various small-scale experiments for thermodynamics have also been developed (Brouwer, 1991), and now several companies have commercialized the small experimental devices combined with sensor equipment. Some unique experiments have also been developed; for example, the color change study involving solvatochromism in biofuels has recently been introduced for undergraduate study (El Seoud et al, 2011). The interaction between proteins is studied by enzyme-linked immunosorbent assay (ELISA) (Johnson et al, 2017).…”

A series of small-scale/micro-scale experiments used for the education of undergraduate students in chemical engineering courses have been developed. Based on the “small-scale/micro-scale” concept, the experiments were developed to provide an intuitive understanding of chemical processes, both by increasing the visibility of these chemical processes and by making the apparatus compact (desktop size). Nine experiments were developed that are relevant to the fields of thermal engineering, fluid engineering, unit operations, and reaction engineering. These experiments were introduced during the educational experiment course for undergraduates in the chemical engineering program.
