ab: Summary: Motivated by the work of Richardsonâ€™s extrapolation spreadsheet
calculator up to level 4 to approximate definite differentiation, we
have developed a Romberg integral spreadsheet calculator to approximate
definite integral. The main feature of this version of spreadsheet
calculator is a friendly graphical user interface developed to capture
the needed information to solve the integral by Romberg method. Users
simply need to enter the variable in the integral, function to be
integrated, lower and upper limits of the integral, select the desired
accuracy of computation, select the exact function if it exists and
lastly click the Compute button which is associated with VBA
programming written to compute Romberg integral table. The full
solution of the Romberg integral table up to any level can be obtained
quickly and easily using this method. The attached spreadsheet
calculator together with this paper helps educators to prepare their
marking scheme easily and assist students in checking their answers
instead of reconstructing the answers from scratch. A summative
evaluation of this Romberg Spreadsheet Calculator has been conducted by
involving 36 students as sample. The data was collected using
questionnaire. The findings showed that the majority of the students
agreed that the Romberg Spreadsheet Calculator provides a structured
learning environment that allows learners to be guided through a
step-by-step solution.
