The development of information and communication technology also provides convenience and practicality in the world of education. In this paper, an alternative solution is presented for the discussion of energy band material in Body Centered Cubic (BCC) based on tight binding in distance material physics lectures. These activities take advantage of technology assistance in the form of spreadsheet software. Spreadsheet software is used in this research because it is a computational software that can visualize a graphic according to user commands. The use of spreadsheets is also due to being one of the computational programs that are easy to access, operate, and often used by students, especially during the current conditions affected by the Covid-19 pandemic. This research presents a simple way for students to visualize the energy band from BCC through the spreadsheet assistance. This visualization of the energy bands in BCC begins by describing the appropriate mathematical equation. Next, visualize the mathematical equation in graphical form with the spreadsheet assistance. This visualization activity can also be applied to students in material physics courses to help students understand the various characteristics of solids that have the form of BCC in everyday life. Distance material physics lectures that implement the visualization process can increase student creativity to visualize various forms of energy bands of each solid substance present. © 2022, Walailak University.
