Educational robotics for science and mathematics teaching: Analysis of pre-service teachers' perceptions and self-confidence.

Educational Robotics has had an important impact in recent years as it offers a number of advantages for students. The inclusion of robotics in any educational stage requires teachers with adequate predisposition and training, making it necessary to know the opinions of pre-service teachers. The aim of our study is to analyze the perceptions and self-confidence of 109 pre-service primary education teachers before and after an intervention based on educational robotics and challenge-based learning to teach scientific and mathematical content, in their third academic year.

The Promotion of Healthy Hydration Habits through Educational Robotics in University Students.

In recent years, there has been a lack of healthy lifestyle habits in the population, including hydration, with negative consequences for health. At the same time, advances in technology have changed the process of teaching and learning since elementary school, highlighting the incorporation of educational robots as innovative resources in recent years. This study analyzes the state of the scientific knowledge presented by university students doing a university degree in Primary Education after a robotics-based educational intervention.

An approach to epistemic emotions in physics' teaching-learning. The case of pre-service teachers.

It is well established that emotions play a key role in the teaching-learning process and cognitive and affective factors should receive especial consideration. This fact becomes even more important when dealing with pre-service teachers, since their emotions towards science will be projected into their future practice as early-childhood teachers. It has been also stated the influence of the instructional approach in which the teaching-learning process is based on the emotions of students towards science.

Improving the self-regulation in prospective science teachers: the case of the calculus of the period of a simple pendulum.

This paper addresses the need to perform laboratory activities in secondary education science subjects, and what prospective science teachers feel while they themselves are doing these activities in their initial training. A laboratory activity based on the calculation of the oscillation period of a simple pendulum was done with 12 prospective teachers at the University of Extremadura, who were specializing in Biology/Geology, Physics/Chemistry, and Mathematics. When they had finished the activity they filled out a questionnaire about the difficulty, reasoning, capability, and emotions they had experienced in each of the stages needed to resolve the problem.

High-performance liquid chromatographic determination of glyoxal and methylglyoxal in urine by prederivatization to lumazinic rings using in serial fast scan fluorimetric and diode array detectors.

Glyoxal and methylglyoxal are two important markers of oxidative stress and both are involved in the evaluation of several diseases. A new HPLC method for determining glyoxal and methylglyoxal in urine was developed. The method is based on the reaction of alpha-dialdehydes, glyoxal and methylglyoxal, with 5,6-diamino-2,4-hydroxypyrimidine sulfate in basic medium to form highly fluorescent lumazine derivatives.
