121	Teachers' perceptions and enactment of inquiry- based teaching to stimulate learner interest in science Mkandla, Justice 22 February 2021 (has links) Abstracts in English, Afrikaans and Zulu / This qualitative, single high school case-study conveniently sampled eight natural sciences teachers and, after conducting lesson observations and document analysis, interviewed all participants to obtain their perceptions about the effectiveness of inquirybased teaching in motivating learners to specialise in sciences. The major finding was that most participants were sceptical about inquiry-based teaching. Participants from a behaviourist epistemology did not believe that learner motivation resulted from inquirybased teaching while those from an eclectic epistemology preferred a complementary use of both approaches. The few participants oriented towards inquiry acknowledged the link between learner motivation and inquiry-based teaching but faced the challenge of limited time to prepare all the apparatus and procedures required for inquiry-based teaching. This researcher recommends employing laboratory assistants to assist teachers with setting up apparatus for inquiry-based lessons, trimming some content to reduce overload in the Annual Teaching Plans (ATP), and in-service training on inquirybased teaching to develop learner interest in sciences. / Hierdie kwalitatiewe gevallestudie het agt natuurwetenskap onderwysers betrek en na leswaarnemings en dokumentanalise, is onderhoude met die deelnemers gevoer om hul sienings te bekom oor die bydrae van die ondersoek-gebaseerde konstruktivistiese benadering as ’n strategie om leerders te motiveer om in wetenskap-verwante vakke te spesialiseer. Die belangrikste bevindings was dat die deelnemers logiese positivistiese en eklektiese benaderings verkies; dat hulle skepties is oor ondersoek-gebaseerde onderrig en dat hulle nie leerder motivering aan onderwysbenaderings koppel nie. Daar was egter enkele deelnemers wat wel ondersoekend onderrig het en wat leerder belangstelling in wetenskap aan ondersoek-gebaseerde onderrig gekoppel het. Op grond van die data wat verkry is, beveel hierdie navorser aan dat laboratoriumassistente aangestel moet word om onderwysers by te staan met die opstel van apparaat vir ondersoek-gebaseerde lesse; dat spesifieke modelle van ondersoek in die “CAPS”- dokument ingesluit word; dat inhoud afgeskaal moet word om oorlading in die jaarlikse onderrigplanne (ATP) te verminder, en dat voor- en indiensopleiding aan onderwysers oor ondersoek-gebaseerde onderrig verskaf word as ‘n manier om die belangstelling van die leerders in die wetenskappe te prikkel. / Lesisifundo socwaningo esenziwe esikoleni esisodwa samabanga aphakeme lwakhetha othisha beSayensi Yemvelo (NS) abayisishiyagalombili ukuze kwazakale ukuthi bayibona kanjani indlela yokufundisa iSayensi ngophenyo (inquiry-based teaching) ehlose ukukhuphula intshisekelo yabafundi kwiSayensi. Ngemuva kokubona othisha beSayensi befundisa, lomcwaningi wahlaziya incwadi eziphathelene nokufundiswa kohlelo lwe CAPS, waphinde wenza izingxoxo nabothisha. Okumqoka okutholakale kuloluphenyo kube ukuthi iningi lababambe iqhaza, abakhuthalela ukufundisa ngendlela egxile kuthisha (logical positivism) bangabaza ukuthi abafundi bafunde bephenya njalo abakubonanga ukuxhumana kwenzindlela zokufundisa nokunyuka kwentshiseko yabafundi ezifundweni ze Sayensi. Ababambiqhaza abahlanganisa indlela yokufundisa egxile kuthisha ne ndlela yokufundisa ngophenyo (eclectic) bakholelwa ukuthi indlela yokufundisa egxile kuthisa nendlela yokuthi abafundi bafunde bephenya, kuyomela zisetshenziswe zombili.

122	Evaluation of a Novel Biochemistry Course-Based Undergraduate Research Experience (CURE) Stefan M Irby (6326255) 15 May 2019 (has links) <p>Course-based Undergraduate Research Experiences (CUREs) have been described in a range of educational contexts. Although various learning objectives, termed anticipated learning outcomes (ALOs) in this project, have been proposed, processes for identifying them may not be rigorous or well-documented, which can lead to inappropriate assessment and speculation about what students actually learn from CUREs. Additionally, evaluation of CUREs has primarily relied on student and instructor perception data rather than more reliable measures of learning.This dissertation investigated a novel biochemistry laboratory curriculum for a Course-based Undergraduate Research Experience (CURE) known as the Biochemistry Authentic Scientific Inquiry Lab (BASIL). Students participating in this CURE use a combination of computational and biochemical wet-lab techniques to elucidate the function of proteins of known structure but unknown function. The goal of the project was to evaluate the efficacy of the BASIL CURE curriculum for developing students’ research abilities across implementations. Towards achieving this goal, we addressed the following four research questions (RQs): <b>RQ1</b>) How can ALOs be rigorously identified for the BASIL CURE; <b>RQ2</b>) How can the identified ALOs be used to develop a matrix that characterizes the BASIL CURE; <b>RQ3</b>) What are students’ perceptions of their knowledge, confidence and competence regarding their abilities to perform the top-rated ALOs for this CURE; <b>RQ4</b>) What are appropriate assessments for student achievement of the identified ALOs and what is the nature of student learning, and related difficulties, developed by students during the BASIL CURE? To address these RQs, this project focused on the development and use of qualitative and quantitative methods guided by constructivism and situated cognition theoretical frameworks. Data was collected using a range of instruments including, content analysis, Qualtrics surveys, open-ended questions and interviews, in order to identify ALOs and to determine student learning for the BASIL CURE. Analysis of the qualitative data was through inductive coding guided by the concept-reasoning-mode (CRM) model and the assessment triangle, while analysis of quantitative data was done by using standard statistical techniques (e.g. conducting a parried t-test and effect size). The results led to the development of a novel method for identifying ALOs, namely a process for identifying course-based undergraduate research abilities (PICURA; RQ1; Irby, Pelaez, & Anderson 2018b). Application of PICURA to the BASIL CURE resulted in the identification and rating by instructors of a wide range of ALOs, termed course-based undergraduate research abilities (CURAs), which were formulated into a matrix (RQs 2; Irby, Pelaez, & Anderson, 2018a,). The matrix was, in turn, used to characterize the BASIL CURE and to inform the design of student assessments aimed at evaluating student development of the identified CURAs (RQs 4; Irby, Pelaez, & Anderson, 2018a). Preliminary findings from implementation of the open-ended assessments in a small case study of students, revealed a range of student competencies for selected top-rated CURAs as well as evidence for student difficulties (RQ4). In this way we were able to confirm that students are developing some of the ALOs as actual learning outcomes which we term VLOs or verified learning outcomes. In addition, a participant perception indicator (PPI) survey was used to gauge students’ perceptions of their gains in knowledge, experience, and confidence during the BASIL CURE and, therefore, to inform which CURAs should be specifically targeted for assessment in specific BASIL implementations (RQ3;). These results indicate that, across implementations of the CURE, students perceived significant gains with large effect sizes in their knowledge, experience, and confidence for items on the PPI survey (RQ3;). In our view, the results of this dissertation will make important contributions to the CURE literature, as well as to the biochemistry education and assessment literature in general. More specifically, it will significantly improve understanding of the nature of student learning from CUREs and how to identify ALOs and design assessments that reveal what students actually learn from such CUREs - an area where there has been a dearth of available knowledge in the past. The outcomes of this dissertation could also help instructors and administrators identify and align assessments with the actual features of a CURE (or courses in general), use the identified CURAs to ensure the material fits departmental or university needs, and evaluate the benefits of students participating in these innovative curricula. Future research will focus on expanding the development and validation of assessments so that practitioners can better evaluate the efficacy of their CUREs for developing the research competencies of their undergraduate students and continue to render improvements to their curricula.</p> Biochemistry Education Course-based Undergraduate Research Course-based Research Experiences CURE anticipated learning outcomes ALOs ALO CURAs research abilities PICURA ALO matrix BASIL weighted-relevance WR verified learning outcomes VLOs CUREs biochemistry computational biochemistry bioinformatics biochemistry education chemistry education chemistry teaching laboratory upper-division ACE-Bio experimental competencies Authentic science inquiry chemical education assessment assessment design Student understanding student difficulties biochemistry laboratory experiments biochemistry teaching laboratory chemistry teaching laboratory chemistry teaching laboratories predicting protein function protein inquiry-based learning inquiry-based teaching content analysis open-ended survey interviews semi-structured interviews PPI participant perception indicator assessment triangle CRM conceptual reasoning mode conceptual-reasoning-mode model curriculum evaluation experimental abilities discovery skills learning objectives learning outcomes LO LOs collaborations collaborative course implementation implementation student difficuluties experimental learning experimental literacy data-representation ACE-Bio Network Likert-survey
