Purpose
– This paper aims to present a research outcome to an investigation towards the innovative use of electronic-learning (e-Learning) software solutions to strengthen the interactive component of mobile learning (m-Learning) in university contexts. This work was motivated by observations of interactive limitations in existing m-Learning solutions in well-intentioned software development and e-Learning efforts. The aim of the project, thus, was to interrogate hindrances to the potency of m-Learning interventions. The idea was to strengthen the interactive component, to improve the compatibility of the desktop e-Learning process – with mobile appliances such as mobile phones and, finally, to explore cost minimizing avenues of downloading learning materials over mobile phones.

Design/methodology/approach
– The methodology of the project was twofold: that is, both literature-based and experimental. Literature background offered insight on existing efforts towards interactive m-Learning solutions. Against this background, the project was then designed to explore ways to provide presentations and interactive chats for effective m-Learning over mobile phones. The idea was to reduce the file size of presentations slides for effective display on mobile devices. Finally, the aim was also to minimize airtime costs when transmitting presentation slides and when conducting interactive chats on mobile phones. An experiment research method was, thus, used. In this method, a problem and question were articulated first. Then, a practical technological solution was conceptualized, developed, pre-tested, modified and re-tested until it complied with sought specifications, Finally, the solution was implemented, to confirm its viability and response to a research problem and, ultimately, was reported in the findings.

Findings
– Slides were developed with light colour resolutions to open effortlessly on tiny mobile screens. The best quality was between 128 and 201.188 (out of 255) pixels (more visible mobile phone screens), using Open Source Software. Clear slides also had a font greater than size 32. The average data per presentation were 9,872.66 bytes, and, when seven learners were chatting, it was 3,686.63 bytes (0.03 megabytes). For airtime costs, the Vodacom rate of R0.46 per megabyte was used. This translates to 0.8 × 0.46 = R0.0368 cost per slide. The m-Chisimba platform therefore, seems to be cost-effective, quality expedient and most appropriate for interactive m-Learning.

Research limitations/implications
– Existing m-Learning has been inadequate, failing to align adequately the desktop e-Learning solutions with mobile phone platforms. Desktop presentation slides, for example, have been incompatible with mobile phones’ operations and screen sizes. Mostly, content could consume a lot more airtime, owing to large sizes of desktop originated material that was incompatible with mobile platforms. A solution that emerged from original experiments, leading to the enhanced interactive m-Learning solution, the m-Chisimba platform, is, therefore, presented in this paper. The thinking is that mobile applications are convenient enablers which extend access to information. Nevertheless, mobile applications (including m-Learning solutions) cannot be seen as panaceas to solve all learning concerns as literacy and affordability remain challenges in many under-developed social environments. As a newly developed innovation, the m-Chisimba platform offers an improved m-Learning solution for learning activities over mobile gadgets such as mobile phones.

Practical implications
– The research work offers new innovative solutions in a number of practical ways. It improves the interactivity component of the m-Learning process, to empower educators and learners to effectively engage learning over m-Learning devices.

Social implications
– The innovation makes it easier to for learning to take place effortlessly, over mobile platforms. Implications are that more people will be able to access learning processes on the move, meaning that obstacles to access learning opportunities are minimised.

Originality/value
– Existing m-Learning has been inadequate, failing to align adequately the desktop e-Learning solutions with mobile phone platforms. Desktop presentation slides, for example, have been incompatible with mobile phones’ operations and screen sizes. Mostly, content could consume a lot more airtime, owing to large sizes of desktop-originated material that was incompatible with mobile-platforms. A solution that emerged from original experiments, leading to the enhanced interactive m-Learning solution, the m-Chisimba platform, is, therefore, presented in this paper. The thinking is that mobile applications are convenient enablers which extend access to information. Nevertheless, mobile applications (including m-Learning solutions) cannot be seen as panaceas to solve all learning concerns as literacy and affordability remain challenges in many under-developed social environments.
