Systematic review and exploratory meta-analysis of the efficacy, safety, and biological effects of psychostimulants and atomoxetine in patients with …
2019
ObjectiveOur aim was to summarize the efficacy and safety of atomoxetine, amphetamines, and methylphenidate in schizophrenia.MethodsWe undertook a systematic review, searching PubMed/Scopus/Clinicaltrials.gov for double-blind, randomized, placebo-controlled studies of psychostimulants or atomoxetine in schizophrenia published up to 1 January 2017. A meta-analysis of outcomes reported in two or more studies is presented.ResultsWe included 22 studies investigating therapeutic effects of stimulants (k=14) or measuring symptomatic worsening/relapse prediction after stimulant challenge (k=6). Six studies of these two groups plus one additional study investigated biological effects of psychostimu…
Competencia Científica y Resolución de Problemas de Física
2020
Resumen Impulsar y desarrollar la competencia científica entre los estudiantes que cursan materias como la Física, es un objetivo contemplado actualmente de forma explícita en la mayoría de los currículos escolares y es compartido por muchos expertos en Didáctica de las Ciencias Experimentales. Sin embargo, cuando se trata este tema con el profesorado de ciencias, suele hacerse ignorando los contenidos concretos de la materia a enseñar, con lo cual, los profesores difícilmente pueden trasladar a sus clases aquello que les ha sido expuesto en términos demasiado generales o abstractos. En nuestra opinión, si realmente se quiere impulsar y desarrollar la competencia científica, ello ha de hace…

Open-ended projects opened up — aspects of openness
2017
Abstract—One of the most important areas of competence for professional engineers is the ability to function well in project work, in particular they need to be able to efficiently solve open-ended problems in different collaborative settings. The development of this ability is however not prominent in engineering education despite numerous authors suggesting openended problems as a pedagogical tool to promote development of collaborative problem solving competence by including elements of group or project work in courses. In our own long experience of using open-ended problems in collaborative student projects, we have identified a lack of systematic progression in learning outcomes and sk…
Visual understanding of divergence and curl: Visual cues promote better learning
2019
Prior research has shown that students struggle to indicate whether vector field plots have zero or non-zero curl or divergence. In an instruction-based eye-tracking study, we investigated whether visual cues (VC) provided in the vector field plot can foster students’ understanding of these concepts. The VC were only present during instruction and highlighted conceptual information about vector decomposition and partial derivatives. Thirty-two physics majors were assigned to two groups, one was instructed with VC about the problemsolving strategy, and one without. The results show that students in VC-condition performed better, responded with higher confidence, experienced less mental effor…

2018
Bakalaura darbā tiek pētīta skolēnu teksta uzdevumu risināšanas veicināšana matemātikas mācībā 2.klasē. Bakalaura darba autore ir Aleksandra Gorškova. Darba mērķis ir izzināt skolēnu teksta uzdevumu risināšanas veicināšanu matemātikas mācībā 2. klasē un apkopot ieteikumus par skolēnu teksta uzdevumu risināšanas veicināšanu matemātikas mācībā sākumskolā. Bakalaura darbs sastāv no divām daļām – teorētiskās un empīriskās. Darba teorētiskā daļa balstīta uz M. Ovčinnikovas (2001), I. Marčenko (2011), A. Belošistajas (2007), N. Istominas (2001), J. Menča (2014), M. Moro un A. Piškalo (1975), I. Dubrovinas (2003) un citu autoru teorētiskajām atziņām. Teorētiski analizēta matemātikas mācības būtība…
Patterns of action transitions in online collaborative problem solving : A network analysis approach
2022
AbstractIn today’s digital society, computer-supported collaborative learning (CSCL) and collaborative problem solving (CPS) have received increasing attention. CPS studies have often emphasized outcomes such as skill levels of CPS, whereas the action transitions in the paths to solve the problems related to these outcomes have been scarcely studied. The patterns within action transitions are able to capture the mutual influence of actions conducted by pairs and demonstrate the productivity of students’ CPS. The purpose of the study presented in this paper is to examine Finnish sixth graders’ (N = 166) patterns of action transitions during CPS in a computer-based assessment environment in w…
Hothousing: Utilising industry collaborative problem-solving practices for STEAM in schools
2022
Collaborative problem solving (CPS) has been widely used in both industry and in schools over at least the last twenty years. The Industry Hothousing variant of CPS in its adult format is an intensive, time-constrained workshop based process designed to build mutual trust between customers and industry experts in order to synergically develop creative solutions together. Its potential use in schools raises two important questions: Firstly, what degree of structure and support is required to unleash student creativity and enhance learning - as in industry or does the student need more structured methods including explicitly being taught collaborative problem solving skills? Secondly, is CPS …
