Context. Be stars are rapidly rotating with a circumstellar decretion disk. They usually undergo pressure and/or gravity pulsation modes excited by the κ-mechanism, i.e. an effect of opacity iron-peak elements in envelope star. In Milky Way, p-modes observed that hotter than or equal to B3 spectral type, while g-modes at B2 type and cooler.
Nowadays, Augmented Reality (AR) is one of the emerging technologies with a greater impact in Education field. Research has proved that AR-based activities improve teaching and learning processes. Also, use this type technology classroom facilitates understanding contents from different areas as Arts, Mathematics or Science. In work we propose an instruction order to explore benefits 6th-grade Primary course related 3D-geometry shapes. This first experiment, designed exploratory approach,...
The COVID-19 pandemic led to the lockdown of schools in many countries, forcing teachers and students carry out educational activities remotely. In case mathematics, developing remote instruction based on both synchronous asynchronous technological solutions has proven be an extremely complex challenge. Specifically, this was topics such as word problem solving, domain requires intensive supervision feedback from teacher. piece research, we present evaluation how technology is employed...

The presence of pulsations in late-type Be stars is still a matter controversy. It constitutes an important issue to establish the relationship between non-radial and mass-loss mechanism stars. To contribute this discussion, we analyse photometric time series B8IVe star HD 50209 observed by CoRoT mission seismology field. We use standard Fourier techniques linear non-linear least squares fitting methods light curve. In addition, applied detailed modelling high-resolution spectra obtain...
Educational robotics are commonly present in kindergarten and primary school classrooms, particularly Bee-bot. Its ease of use allows the introduction computer programming to young children educational contexts from a science, technology, engineering, arts, mathematics (STEAM) perspective. Despite this rise, there still few investigations that collect evidence on effectiveness robotic interventions. Although mentoring experiences with had been carried out contexts, work explores their effect...
Context.Stellar pulsations in main-sequence B-type stars are driven by the κ-mechanism due to Fe-group opacity bump. The current models do not predict presence of instability strips B spectral domain at very low metallicities. As metallicity SMC is lower than , it constitutes a suitable object test these predictions.
Abstract Problem solving is often regarded as one of the most essential cognitive functions in our daily lives, and, for that reason, educational theorists have long stressed need its development. As flexibility a fundamental characteristic necessary throughout problem‐solving process, purpose this study to analyse students' performance after following intra‐task flexibility‐based training mediated by an intelligent tutoring system. With aim, 110 fifth and sixth grade students took part...

Classical Be stars are rapid rotators of spectral type late O to early A and luminosity class V-III, wich exhibit Balmer emission lines often a near infrared excess originating in an equatorially concentrated circumstellar envelope, both produced by sporadic mass ejection episodes. The causes the abnormal loss (the so-called phenomenon) as yet unknown. For first time, we can now study detail outside Earth's atmosphere with sufficient temporal resolution. We investigate variability Star...

Abstract This research, following a sequential mixed-methods design, delves into metacognitive control in problem solving among 5- to 6-year-olds, using two floor-robot environments. In an initial qualitative phase, 82 pupils participated tasks which they directed floor robot one of targets, with the closer target requiring more cognitive effort due turns involved. The results this phase revealed that younger students often rationalised their decisions based on reasons unrelated difficulty...

Computational thinking (CT) has garnered significant interest in both computer science and education sciences as it delineates a set of skills that emerge during the problem-solving process. Consequently, numerous assessment instruments aimed at measuring CT have been developed recent years. However, scarce part existing measurement dedicated to early school ages, few undergone rigorous validation or reliability testing. Therefore, this work introduces new instrument for grades elementary...
Mental rotation and spatial skills are not innate abilities therefore require development. These involve the ability to accurately perceive objects in space, manipulate them mentally, recreate situations without direct sensory input.
