Abstract: This study discusses a study on e-Learning as an alternative mode for teaching mathematics for engineering students, focusing on vector calculus as an instance of application. Mastery of mathematics is vital for engineering students. A strong foundation in mathematics is necessary to ensure engineering students mastery of other engineering courses. Difficulties in mastering mathematics often adversely affect the achievement of enginering students academically. Among the mathematics courses, vector calculus stand out as challenging to many students. This study thus covers the strategy of this alternativemode to enable students comprehension and mastery of the vector calculus. Implementation of e-Learning is supported by learning softwares, maths websites, Wiley-Plus® and Hot Potatoes®. The e-Learning mode enabled students to communicate with the lecturer at any time through an interactive facebook. Similarly, the use of wordpress and google.doc enabled students to communicate or access learning materials at any time. Evidently, the method has enabled students to master vector calculus and engineering mathematics, through visualization enabled by the e-Learning tools.
