Person-centred reviews and transition: an exploration of the views of students and their parents/carers

The person-centred review (PCR) is a model for the review of a student’s special educational needs (SEN) which places the young person and their family at the centre of the process. This mixed-methods, exploratory study investigated the views of 16 students with SEN aged between 10–11 years (Year 6) and 13–14 years (Year 9), and their parents/carers on their PCRs (which were mostly held at transition). Attention was paid to potential changes in the young people’s locus of control and feelings towards school. Findings indicated that the PCR is a collaborative, constructive and reassuring process for families where a wealth of information is shared openly and honestly within a relaxed, yet structured, meeting. The young people were generally positive about the process, although many felt daunted beforehand. Some parents felt the meeting was too long and not entirely accessible to children. The study did not conclude that the young people’s locus of control or feelings towards their education changed following the PCR. Implications for good practice are discussed, particularly for educational psychologists and in the context of the SEN and Disability Code of Practice.

Revisiting free school meal eligibility as a proxy for pupil socio‐economic deprivation

Whether someone has ever had free school meal (FSM) eligibility over a six‐year period is the measure of socio‐economic disadvantage currently used in the English school system. It is used to monitor the socio‐economic gap in achievement in the education system, to identify particular children at risk of low achievement and to direct funding to particular children and schools. In this paper we assess how well this measure predicts pupil attainment in secondary school in comparison to other measures of socio‐economic background known to influence pupil attainment, such as parental education or income. We ask whether the FSM measure is an adequate proxy for a pupil's socio‐economic disadvantage in an educational context. To do this we draw on the Longitudinal Study of Young People in England and matched administrative data. We find that the FSM eligibility measure correlates highly with other measures of socio‐economic disadvantage, however it does not identify all children living in what would be deemed deprived households. We then compare the extent to which the FSM eligibility measure predicts educational achievement relative to other measures of deprivation and find that its predictive power is only marginally lower than many richer survey measures. This provides some reassurance on its use in policy.

Enhanced teaching and student learning through a simulator-based course in chemical unit operations design

This paper illustrates a teaching technique used in computer applications in chemical engineering employed for designing various unit operation processes, where the students learn about unit operations by designing them. The aim of the course is not to teach design, but rather to teach the fundamentals and the function of unit operation processes through simulators. A case study presenting the teaching method was evaluated using student surveys and faculty assessments, which were designed to measure the quality and effectiveness of the teaching method. The results of the questionnaire conclusively demonstrate that this method is an extremely efficient way of teaching a simulator-based course. In addition to that, this teaching method can easily be generalised and used in other courses. A student's final mark is determined by a combination of in-class assessments conducted based on cooperative and peer learning, progress tests and a final exam. Results revealed that peer learning can improve the overall quality of student learning and enhance student understanding.
