1.0 INTRODUCTION

Based on observations and report from students who have taken the Engineering Mathematics

2 course, they tend to lost, misplaced and forget to bring the formula sheet involving basic

calculus during mathematics class. The formula sheet needs to be use throughout the semester

but the problems keep occurring as the formula is not easily access. So, we decide to create

and develop mobile apps to support teaching and learning (iCalculus). iCalculus is a mobile

application contains basic calculus on differentiation and integrations. Students with smart

phone can easily download it and access every time and everywhere.

2.0 OBJECTIVES

Main objectives are to support teaching and learning process. The research objectives can be

summarised as the followings:

a) Facilitate students’ access to basic differentiation and integration.

b) Provide students’ on the go formulas and practices.

c) Reduce the use of paper.

3.0 DURATION

ICalculus had been fully operated on 17th

June 2015 and students can download it through

Google Playstore for android user and Apple Store for Iphone user.

4.0 TARGET AUDIENCE

Since launch, ICalculus had been downloaded more than 100 people and most of the students

already downloaded it in their smart phone.

5.0 PROBLEM STATEMENT

Problem statement can generally be categorized into four such as:

a) Students easily get rid of the formula sheets.

b) Limit accessibility to the formula because it is easily tear apart.

c) Disorganized formula lead students to choose the wrong formula for answering

questions related.

d) Students do fewer practices.

6.0 BENEFITS

Benefits of iCalculus mobile apps are consists of four elements:

6.1 Creativity

i. Attractive display and arrangement in the mobile application facilitate the students

to identify formula easily

ii. The practice inserted after formula lets student enhance their understanding of the

correct use of the formula

6.2 Phase progress

i. The mobile application ICalculus has been uploaded to Google Play Store (Android

user) and Apple Store (Apple User).

ii. Students have downloaded onto their smartphones.

6.3 Merchantability

i. This application can be downloaded by all users of smart phones version 4.0 and

above and all ages 12 years and older for free.

6.4 Efficiency

i. All smartphone users can access ICalculus mobile applications anywhere.

ii. Formula on the ICalculus may be referred at any time without internet access if

already downloaded on smart phones.

iii. Students can create a self- training related to differentiation and integration

anywhere.

7.0 ANALYSIS DATA

This section presented an overview of the two types of analysis data from questionnaire in the

table. It presents about analysis of mobile application and content of mobile application.

In this section, researchers discussed the related mobile applications. Analysis of this

section is based on the 8 questions contained in the questionnaire on the part A. In the first

statement, that ‘I found the picture and set of formulas is interesting’, a total of 57 of

respondents (86.4 %) strongly agreed with this statement. This is followed by 6 of

respondents (9.1 %) agreed , two of respondents (3 %) said it was not sure , one of

respondents (1.5 %) disagree and no one (0 %) were strongly disagree.

In the second statement , which ‘I found the icons / buttons in mobile applications

easy to understand lesson’ , frequency and percentage of strongly agree and agree respectively

by 51 of respondents (77.3 %) and 11 of respondents (16.7 %). This is followed by 7 of

respondents (6.1% ) were not sure . None of the respondents strongly disagreed in this

statement.

Further, the majority of respondents, 52 of them (78.8 %) strongly agreed with the

third statement say that ‘I found the presentation app is interesting’. This is followed by 11 of

respondents (16.7 %) agreed. However, there were three respondents (4.4 %) were not sure in

this statement.

The study also showed that 52 of respondents (78.8 %) strongly agreed with the

statement that ‘I easily access content using the icons / buttons in the application of mobile

learning’. 10 of respondents (15.2 %) were agreed with this statement but four of respondents

(6.1 %) were not sure with this statement.

A total of 54 respondents (81.8 %) strongly agreed with the fifth statement while nine

of them (13.6 %) were agreed. Only three of respondents (4.5 %) were not sure with the

statement that ‘I found the display of applications on the smartphone screen is clear.’

From the sixth statement, 53 of respondents (80.3 %) strongly agree with the statement

‘I found the size of the letters on learning app is easy to read’, and 10 of respondents (15.2 %)

agreed with this statement. Three of respondents or 4.5 % of respondents were not sure with

this statement.

The next statement, there were 53 of respondents (80.3 %) strongly agreed that ‘I

found a set of content on the display easily accessible mobile applications’. A total of 11

respondents (16.7 %) agreed with this statement. However, one (1.5 %) of respondents was

not sure, and one (1.5 %) was not agreed.

For the last statement, there were 53 of respondents (80.3 %), strongly agreed and 10

of respondents (15.2 %) agreed with the statement ‘I found the colors used in mobile

applications is attractive learning’. Only 3 of respondents (4.5 %) were not sure with this

statement.

In this section, researchers will discuss the contents of mobile application. The analysis in this

section is based on six questions contained in the survey forms part B.

The ninth statement, which ‘I enjoy learning using mobile applications compared with

traditional instruction methods’, it was found that 56 of respondents (84.8 %) strongly agreed

with this statement. This is followed by 8 of respondents or 12.1 % were agreed with this

statement. Only 2 of them respondents (3 %) were not sure with this statement.

In the tenth statement, 51 of respondents (77.3 %) strongly agreed that I understand

the language used in the application of mobile learning. This is followed by 14 of respondents

(21.2 %) of respondents agreed. Only one respondent (1.5 %) did not agree to this statement

Further, the majority of respondents ,52 of them (78.8 %) strongly agreed with the

statement that says that ‘I find examples and exercises in learning mobile application helps

me understand learning’ but as many as 12 of respondents (18.2 %) were agreed with this

statement . However there was one person (1.5 %) were not sure and one of respondents (1.5

%) was not sure in this statement.

The results also show that as many as 56 of respondents (84.8 %) strongly agreed with

the statement that ‘I prefer to fourth refer to mobile applications to solve problems than

formula sheet.’ There were 7 of respondents (10.6 %) were agreed with this statement, but

there were 3 of respondents (4.5 %) were not sure in this statement.

Most of respondents, 53 of them (80.3 %) strongly agreed with the thirteenth

statement while 10 of respondents (15.2 %) were agreed. Only one of the respondents (1.5 %)

was not sure and 2 of respondents (3 %) disagreed with the statement that I'm easier to raise

the awareness of using mobile apps than written training’.

For the last statement, a total of 53 respondents (80.3 %) of respondents strongly

agreed that the statement of this method is suitable for other topics and 10 of respondents

(15.2 %) were agreed with this statement. Three of respondents or 4.5 % were not sure with

this statement.

8.0 CONCLUSION

The results of the survey conducted on 70 respondents, over 80 % percent of users said that

this mobile application makes it easy for them to access and easy to understand the content

allows them to understand the concept easily. An interesting display, organized and easily

accessible makes iCalculus is one of the appropriate reference materials for students at higher

education institutions.
