The Maths Learning Centre (MLC) was first established as a library service in 1994 but initially struggled for funding and recognition at a wider University level. Since 2000 it has been incorporated into the centrally funded Student Learning Advisory Service (SLAS).

format, Teaching Mathematics and its Applications 2013 32(4), 206-213 doi:

The purpose of this study was to observe students’ retention, success and attitudes towards mathematics in a community college quantitative literacy course, taught in a lab-based format. The redesigned course implemented the daily use of Microsoft Excel in the classroom demonstrations, group activities and individual assignments, and utilized data from many fields of study. Results showed statistically significant growth in attitudes towards real-world application problems, the use of computers in mathematics, and the consideration of taking additional mathematics courses. There was also marginally significant growth in students’ attitudes towards the relevance and utility of mathematics. Higher retention and success rates in the redesigned course were also observed, although those rates were not found to be statistically significant.

The Study Support Centre (SSC), within the Robert Gordon University (RGU), aims to provide students with assistance in Mathematics, Writing & Communication skills, Information & Communication Technology applications, Statistics, Study Skills and support for dyslexic students. The SSC offers students independent assistance through individual and small group tuition outwith their normal programme of study, as well as Computer Assisted Learning (CAL) packages, specialist software for special needs students and text based self-learning materials. The SSC has created a basic mathematics diagnostic assessment, which we give to first year students in many Schools. Currently, in collaboration with the School of Engineering, an engineering principles diagnostic assessment is being designed and implemented.

In this unit we see how finite and infinite series are obtained from finite and
infinite sequences. We explain how the partial sums of an infinite series form
a new sequence, and that the limit of this new sequence (if it exists) defines
the sum of the series. We also consider two specific examples of infinite
series that sum to e and pi respectively.

A report by Brendan Cooney on a project is to investigate possible technologies that enable the transmission of mathematical content, conversations in mathematics, the posing of problems and transfer of solutions in an effective and efficient manner. The intention is to trial various technologies and then to implement the chosen technology for online delivery of mathematics support to RMIT students. (2013)

The past decade or so has seen a huge growth in the number of mathematics
support centres within UK higher education institutions as they come to terms
with an increasing volume of students who are poorly prepared for the
mathematical demands of their chosen courses. In other parts of the world we
observe similar developments. In the early years many centres were short-lived
enterprises staffed either by concerned volunteers who found a few hours in the
week to offer additional support, or alternatively by part-time staff on short-term
contracts. More recently, we have observed a trend to more substantial support
centres many of which attract central funding and dedicated staff. Given this
trend there is a need to ask whether our efforts are worthwhile, how we might
know this, and whether we can justify ongoing funding. This talk by TONY CROFT from Loughborough University at the 3rd Irish Workshop on Mathematics Learning Support Centres, 2008, NUI Maynooth will describe
some of the challenges associated with acquiring data on effectiveness. Various
ways in which we can measure our success will be explored. Finally, several
exemplars will be provided of work being undertaken to capture the sort of
evidence required to secure continued funding of mathematics support centres.

Cheryl Voake, Lisa Taylor and Rob Wilson. (2013) Transition difficulties from FE to HE - What is the situation and what can we do about it? MSOR Connections, Volume 13, Issue 2: 6-14. DOI: 10.11120/msor.2013.00014
A common complaint from staff in Higher Education (HE) is that students arrive from Further Education (FE) providers with a lack of awareness of what to expect at university. This is manifested by an unpreparedness and, in some cases, an unwillingness for autonomous learning and self-responsibility.
This study was designed to assess student awareness and preparedness for HE, with a particular focus on Mathematics. This was achieved via FE student and teacher questionnaires and a focus group, which crucially allowed judgement between studentsâ?? perceived awareness and their actual awareness. The focus group also gave FE students an opportunity to quiz HE students on their experiences and opinions, and gave the HE students the opportunity to provide information they felt was missing from their own transition to university.

A common mathematical problem is to find the angles or lengths of the sides of a triangle when some, but not all, of these quantities are known. It is also useful to be able to calculate the area of a triangle from some of this information. (Mathtutor Video Tutorial)

The sine, cosine and tangent of an angle are all defined in terms of
trigonometry, but they can also be expressed as functions. In this unit we
examine these functions and their graphs. We also see how to restrict the
domain of each function in order to define an inverse function.

Ni fhloinn, E., Bhaird, C. M., & Nolan, B. (2014). University students' perspectives on diagnostic testing in mathematics. International Journal of Mathematical Education in Science and Technology, 45 (1), 58-74. DOI:10.1080/0020739X.2013.790508
Many universities issue mathematical diagnostic tests to incoming first-year students, covering a range of the basic concepts with which they should be comfortable from secondary school. As far as many lecturers are concerned, the purpose of this test is to determine the students' mathematical knowledge on entry. It should also provide an early indication of which students are likely to need additional help, and hopefully encourage such students to avail of extra support mechanisms at an early stage. However, it is not clear that students recognize these intentions and there is a fear that students who score poorly in the test will have their confidence further damaged in relation to mathematics and will be reluctant to seek help. To this end, a questionnaire was developed to explore studentsâ?? perspectives on diagnostic testing. Analysis of responses received to the questionnaire provided an interesting insight into studentsâ?? perspectives including the optimum time to conduct such a test, their views on the aims of diagnostic testing, whether they feel that testing is a good idea, and their attitudes to the support systems put in place to help those who scored poorly in the test.
