“…Projects have been, static Fourier transform spectrometers, frustrated total internal reflection, optical activity of corn syrup, and the construction of a spectrograph. 17 The investigations are performed by small groups (three students per group) and the students must come to a group consensus on any answer. These groups are assigned by the faculty and change three times through the semester.…”

We have been modifying our intermediate optics class and laboratory with a focus on improving student learning through the use of active engagement. To facilitate this process we developed a two pronged solution. For the classroom we created a series of tutorials to help the students use the mathematics and techniques of derivations, apply these solutions to other problems, and develop a stronger conceptual foundation in intermediate optics class. In the optics laboratories we developed an approach that relies upon direct confrontation of misconceptions, predictions, collection of data to support or refute the predictions, reconciliation, discussion, and leading questions rather than a series of detailed, cookbook-like instructions as might be found in a traditional laboratory. Through the class and laboratory we build conceptual understanding in subjects like image formation by lenses and mirrors, ray optics, and ultimately elliptical polarization while fostering laboratory independence and helping students erect a new paradigm for learning.

“…19,41 Later, Grove et al and Wilson and co-worker reported spectrographs in which student-designed and tested spectrophotometers were created. 39,40 These previously constructed units served as the foundation of this work, where the SpectroBox was designed to expand the field of currently available spectrometric units to include a remotely constructible and affordable DIY spectrophotometer. SpectroBox was specifically designed for online and hybrid learning conditions under the following design and engineering constraints:…”

In early 2020, the COVID-19 pandemic compelled the field of education to swiftly redesign courses for hybrid and online teaching environments. The lack of in-person learning prompted professionals to rapidly incorporate unique and previously never-seen teaching practices in numerous different fields. One of the biggest challenges that educators have been facing during these difficult times is the lack of hands-on technologybased teaching activites under hybrid and online environments. To mitigate this issue, a small, affordable, and 3D-printed visible spectrophotometer (SpectroBox) was developed to allow instructors to rapidly create a portable instrument and provide a hands-on learning experience for students. SpectroBox is mainly a do-it-yourself at-home platform specifically designed for rapid implementation; thus, instructors can deploy SpectroBox under various learning environments, such as remote and hybrid practices. Included parts are in a small package and are transportable via standard parcel delivery; consequently, students can get access to these spectrometric units rapidly and easily. In this work, detailed design, schematics, and step-by-step instructions are presented for instructors to easily incorporate this system. The SpectroBox project was implemented and tested during the Fall 2020 semester, and student assessment data indicated that the theoretical and practical aspects of visible spectroscopy were better understood by 67% of students with this hands-on learning exercise. The final learning outcome of this project was a broad skillset possessed by students, including 3D printable object design, spectrometer assembly, principles of optical spectroscopy, exploration of design components, basic electronics, data acquisition and processing. SpectroBox helped students to fully understand the fundamentals of visible spectroscopy and ultimately improved their expertise in the field of spectroscopy.

Spectroscopy is a technique for collecting physicochemical data through the transmission, absorption or reflection of incident radiant energy in a sample. Our work is used in common low cost and easy access devices that have a CCD reader. Our idea is a set of devices, such as a cell phone, which contains an optical CCD reader, where these equipment materials, materials, compounds, simplifying the image obtained by these optical devices. As filming obtained by optical CCD reader theses hardware, form decoded and separated into their quantified RGB color channels. Our initial technique consists of the analysis of the pixels of the images of primary light sources, such as: the sun, incandescent lamps, fire, candle flames, matchestick flame, wood combustion, etc. We conclude that it is possible to do a spectroscopic analysis using our technique.
