Assessment of work performed by paired students: a pedagogical experience

“Teamwork” is one of the abilities most valued by employers. In [16] we describe the process of adapting to the ECTS methodologies (for ongoing assessment), a course in computer programming for students in a technical degree (Marine Engineering, UPM) not specifically dedicated to computing. As a further step in this process we have emphasized cooperative learning. For this, the students were paired and the work of each pair was evaluated via surprise tests taken and graded jointly, and constituting a substantial part of the final grade. Here we document this experience, discussing methodological aspects, describing indicators for measuring the impact of these methodologies on the educational experience, and reporting on the students’ opinion of it.

An automatic critical care urine meter

Nowadays patients admitted to critical care units have most of their physiological parameters measured automatically by sophisticated commercial monitoring devices. More often than not, these devices supervise whether the values of the parameters they measure lie within a pre-established range, and issue warning of deviations from this range by triggering alarms. The automation of measuring and supervising tasks not only discharges the healthcare staff of a considerable workload but also avoids human errors in these repetitive and monotonous tasks. Arguably, the most relevant physiological parameter that is still measured and supervised manually by critical care unit staff is urine output (UO). In this paper we present a patent-pending device that provides continuous and accurate measurements of patient’s UO. The device uses capacitive sensors to take continuous measurements of the height of the column of liquid accumulated in two chambers that make up a plastic container. The first chamber, where the urine inputs, has a small volume. Once it has been filled it overflows into a second bigger chamber. The first chamber provides accurate UO measures of patients whose UO has to be closely supervised, while the second one avoids the need for frequent interventions by the nursing staff to empty the container
