Bero-transmisiorako mekanismoak

Helburuak. Egun,denon ahoan dagoen energia baliabideen murriztasunak prozesu termikoen energia-efizientziaren garrantzia goratu du zalantzarik gabe. Ingeniaritza ikasketetan , energia eraldakuntzarekin erlazionaturik dagoen edozein ikasgai edo alorrean, funtsezkoa da energia-trukatzeko mekanismoak ondo ezagutzea ekipoen diseinu efiziente eta egokia lortzeko. Material honen bitartez "bero-transmisioa" gaia irakasteko aurkezpen informatikoak garatu dira, klasean zein sare elektronikoan erabili ahal direnak. Irakaskuntzarako material hau aurkezpen informatikoetan gauzatzen da. Aurkezpen informatikoek gaiaren azalpenerako oso egoki suertatzen den dinamismoa eskaintzeaz gain, fenomeno fisikoaren eta ebazpen matematikoaren ulerpenerako oso lan-tresna boteretsua eskaintzen dute. Norentzat da baliagarria. Material hau, bereziki, Donostiako Unibertsitate Eskola Politeknikoko bi titulaziotan erabiltzen da: Ingeniaritza Mekanikoko "Ingeniaritza Termikoa" ikasgaian eta Ingeniaritza Elektrikoko "Termoteknia eta Sorkuntza Termoelektrikoa" ikasgaian. Oro ohar, Ingeniaritza ikasketetan beroaren transmisiorako kondukzio eta konbekzio mekanismoak aztertzeko baliagarria da.

Dificuldade de berço? Professores de matemática no ensino médio: práticas, formação continuada e juventude

The present paper is focused on pedagogical practices and continued lecturing formation of High School Mathematic teachers. Knowing the essential importance of the teacher at the educational process since he/she is the mediator on knowledge gathering by the scholars and continued formation meaning on that process, we hereby propose to investigate and compare what Math teachers think about their professional role, the kind of continued formation they receive and their development on teacher s knowledge and doing; to gather and compare what do Math teachers know about young people at public and private schools and their demands and as which find out if they link with the way as their students are taught. To develop our comparative research, we chose a qualitative focus and an investigation of ethnographic type. We took as the subject four Math teachers that work with high school 1st and 2nd grades in public and private schools, morning and afternoon shifts and license titles. The research results reveal differences in structural matter between the spaces, but the comparisons between teacher doings and knowledge reveal that the differences refer to the sort of formation and how often do the teachers search for it. Nevertheless, the reports pointed to continued lecturing formation offering and consistence problems and these reflect on their work and on its basis. The knowledge about youth and adolescence, such as theoric and methodological knowledge that lead their practices, are revealers of teachers difficulties in developing their activities according to the target public and nowadays educational demands
