Abstract
In
this paper, the educational methods used to teach experimental inorganic
complex synthesis to bioengineering students are described. The first method
concerns the use of synthetic scales to measure trans-dichlorobisethylenediamminecobalt(III)
chloride complex, which made students appreciate the manufacturing of the
equipment. The second involves indicating the relations between inorganic
complexes and biologically important compounds, namely vitamin12 (Co complex, a
coenzyme), hemoglobin (Fe complex, an oxygen carrier) and cisplatin
(Pt complex, an anticancer drug), through which the
students developed a strong interest in the roles of the complexes. A particularly effective method
was the feedback taken from student’s reports and questionnaires after
experiments. As a result the students were
able to learn sufficient inorganic synthesis techniques for separation,
recrystallization, absorption spectral measurement and purity-estimation. By
measuring the spectra of trans and cis isomers, the
students were also able to understand the difference in color between isomers. In
conclusion, through the above educational methods, the bioengineering students
were motivated and learnt the inorganic synthesis techniques and functions of
inorganic complexes effectively.
