Acguisition of problem-solving skills for 5th grade students in mathematics
ProblÄmu risinÄÅ”anas prasmes ir svarÄ«gas skolÄnu caurviju prasmes, un tÄs ir iespÄjams vingrinÄt, matemÄtikas satura apguvÄ plÄnojot stundas darbu, kurÄ atbilstoÅ”i modelÄtÄ pedagoÄ£iskÄ situÄcijÄ skolÄnam jÄpielieto prasme patstÄvÄ«gi uzdot jautÄjumus, lai iedziļinÄtos un fokusÄtu uzmanÄ«bu uz izvirzÄ«to problÄmu, prasme plÄnot matemÄtiskus paÅÄmienus, lai sasniegtu risinÄjumu, prasme izvÄlÄties un Ä«stenot piemÄrotus matemÄtiskos paÅÄmienus un prasme izdarÄ«t secinÄjumus. PÄtÄ«jumÄ apstiprinÄjÄs, ka Ä«stenojot problÄmu risinÄÅ”anas mÄcÄ«bu pieeju, tiek veicinÄta skolÄnu iesaiste stundas darbÄ un stiprinÄtas problÄmu risinÄÅ”anas prasmes.Problem-solving skills are an important skills for pupils and can be practiced by planning an training job in the math area where, in an appropriately modelled pedagogical situation, a pupil needs to use the skills to ask questions independently in order to look into and focus on the challenge, the skills to plan mathematical techniques to reach a solution, the skills to choose and appropriate mathematical techniques and the ability to draw conclusions. The study confirmed that the implementation of the problem based learning(PBL) promotes the involvement of pupils in training work and acquisition of problem-solving skills
Perinatal outcomes of multiple births conceived through in vitro fertilization compared with spontaneous multiple births
Pregnancies that occur after assisted reproduction procedures constitute high-risk pregnancies. There is a lack of sufficient epidemio-logically based data on this issue in Latvia. The aim of this study was to compare the maternal and perinatal outcomes of multiple pregnancies conceived by in vitro fertilization (IVF) in comparison with spontaneous multiple pregnancies. This retrospective cohort study (2007ā2014) analysed data from population-based Medical Birth Register (MBR). There is a statistically significant increase of multiple births from IVF pregnancies ā an average 2% per year (p < 0.01). Newborns of IVF multiple births have higher odds of low birth weight (OR = 1.2) and congenital anomalies (OR = 1.6). Maternity characteristics showed that mothers in the IVF group were significantly older than those in the control group (ā„35 years) (OR = 2.1) and primipara births (OR = 4.1). Multiple births conceived by IVF have similar outcomes as spontaneously conceived multiples in the perinatal period, although the rates of congenital anomalies after IVF are just slightly higher than in control group
