This study provides support to the characteristics of participatory and anticipatory stages in secondary school pupils’ abstraction of mathematical conceptions. We carried out clinical task-based interviews with 71 secondary-school pupils to obtain evidence of the different constructed mathematical conceptions (Participatory…

A knowledge of the shape of the cornea is of major importance for the planning and monitoring of surgery, and for the correct diagnosis of corneal diseases. Many authors have studied the geometry of the second corneal surface in the…

The chemical effects of acoustic cavitation are obtained in sono-reactors built-up from a vessel and an ultrasonic
source. In this paper, simulations of an existing sono-reactor are carried out, using a linear acoustics model, accounting
for the vibrations of the…

The inventory of the populations of trans-Neptunian objects (TNO) has grown considerably over the last decade. As for other groups of small bodies in our solar system, TNOs are expected to have experienced a collisional evolution owing to their mutual…

Design and optimization of distillation columns for ethanol dehydration, using a hydrocarbon as entrainer, implies a good knowledge of vapor-liquid (VLE), liquid-liquid (LLE) and vapor-liquid-liquid equilibrium (VLLE). Chemical process simulation programs always require the use of a thermodynamic model that…

A concept of pedagogical process knowledge (PPK) is introduced to partner pedagogical content knowledge (PCK). This concept arises from observing the learning of teachers engaged in a course supporting them in introducing more inquiry-based methods into their practice. This course…

The practical difficulties of including students with disabilities and diverse educational needs into regular classrooms are apparent in all countries around the world. Successful implementation of the policy of inclusion depends largely on teachers having the knowledge, skills, and competency…

The purpose of the study was to investigate whether teachers’ knowledge of student assessment was influenced by their gender and if it was related to their teaching experience (years in education). One hundred and twenty six physical education teachers (n=126)…
