Toward assessing scientific thinking : a qualitative analysis of student reasoning among psychology undergraduates

Bezuidenhout, Shaughn 03 1900 (has links)
Thesis (MA)--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: The effectiveness of a research methods course on the scientific thinking skills of a group of second year psychology students was recently reported on by Kagee, Allie and Lesch (2010). As part of this study they developed an instrument, The Scientific in Psychology Scale, comprising 11 questions each of which required (a) the endorsement of one of two binary choices and (b) a written explanation detailing the reasons for the choice. However, their findings were based only a statistical analysis of (a) which allowed for a comparison between a control group and an experimental group as a whole. The present study aims to characterize the patterns of thinking at a more detailed level, by analysing the qualitative data for one of the questions. To this end, an alphanumeric scheme was devised to code the data for the two groups mentioned; namely, first year psychology students who comprised the control group, and second year psychology students who comprised the experimental group. The coding was performed at a fine-grained level from which broader categories were constructed. / AFRIKAANSE OPSOMMING: 'n Verslag oor die effektiwiteit van ʼn navorsingsmetodiek kursus op die wetenskaplike denkvaardighede van ʼn groep tweedejaar sielkunde studente, was onlangs waargeneem deur Kagee, Allie en Lesch (2010). As deel van hierdie studie het hul ʼn instrument ontwikkel, Die Wetenskaplik Denking in Sielkunde Skaal, wat bestaan uit 11 vrae wat elk ʼn (a) borg van een of twee binêre keuses en (b) ʼn geskrewe verduideliking wat die redes vir die besluit, omskryf. Hul bevindings was egter net gegrond op ʼn statistiese analise van (a) wat toegelaat het vir ʼn vergelyking tussen ʼn kontrole groep en eksperimentele groep as geheel. Hierdie studie beoog om die patrone van denke op ʼn meer gedetaileerde vlak te karakteriseer, deur analise van kwalitatiewe data van een van die vrae. Ten einde dit te bereik, is ʼn alfanumeriese skema geskep om die data van die twee reedsgenoemde groepe te kodeer; naamlik, eerste jaar studente wat deel gevorm het van die kontrole groep, en tweede jaar studente wat deel gevorm het van die eksperimentele groep. Die kodering was uitgevoer op ʼn hoogs gedetaileerde vlak waaruit wyer kategorieë gekonstrueer is.

Student Intuitions in Statistical Mechanics

Koerfer, Ebba January 2022 (has links)
This exploratory case study aimed to investigate patterns in student reasoning in statistical mechanics, in order to identify difficulties and develop ideas for future research. Upper-division undergraduate students, taking a course in statistical mechanics, were interviewed in groups. Here we present our findings regarding student difficulties in distinguishing microstates and macrostates, as well as distinguishable versus indistinguishable particles. We also present observed patterns of student reasoning about a simple, discrete system in contact with a heat bath. Our findings reveal problematic student intuitions of the high temperature limit. Several students were, however, able to transfer knowledge from a similar problem involving spin to improve their reasoning. / Denna explorativa fallstudie ämnade att undersöka mönster i studenters resonemang i statistisk mekanik, för att identifiera svårigheter och utveckla idéer för framtida forskning. Studenter i sista året på kandidatprogrammet i fysik, som läste en kurs i statistisk mekanik, intervjuades i grupper. Här presenterar vi våra fynd gällande studenters svårigheter med att skilja på mikrotillstånd och makrotillstånd, såväl som urskiljbara och ourskiljbara partiklar. Vi presenterar också observerade mönster i studenters resonemang kring ett simpelt, diskret system i kontakt med en värmereservoar. Våra fynd avslöjar problematiska intuitioner för gränsvärdet vid hög temperatur. Flera studenter kunde dock överföra kunskap från ett liknande problem, som handlade om spin, för att förbättra deras resonemang.
