Tidskriftsartikel (refereegranskat)abstract
- This is a mainly conceptual and argumentative article which presents a model for enquiry-based teaching (Swedish acronym FDU - frågedrivenundervisning). The purpose is to suggest and discuss how enquiry-based teaching can contribute to organising qualified subject teaching in history, religious education and social studies. This is dealt with through two sections. The first section presents a structure for enquiry-based teaching through tested teaching designs in the three subjects, and the second section discusses certain qualities of enquiry-based teaching that we argue should be maintained. Based on actual teaching and teachers' experiences of designing enquiry-based teaching, the article positions FDU as a subject didactic teaching model. Hordern's (2022) framework for normative knowledge practices forms the theoretical starting point for discussing FDU as a subject didactic model that can help teachers in designing, planning, implementing and evaluating qualified subject teaching.The article argues that FDU can be regarded as a normative knowledge practice that is characterised by the qualities of being enquiry-based, prospective, consistent, assessment-oriented, and continuous.

Enquiries in history : Experiences from a professional development seminar series
- 2021

Ingår i: Professional development 2 (papers).

Konferensbidrag (refereegranskat)abstract
- The aim of the research project (financed by Swedish Institute for Educational Research) is to develop the enquiry method as an educational approach for teachers to develop students’ critical abilities. Enquiry is a student-active method with the potential to enhance students’ learning under the guidance and instruction from proficient teachers. Therefore, it requires high demands on teachers' academic and subject didactical knowledge. The project is a researcher-teacher collaborative study where around thirty teachers from three school subjects (history, religious education and social studies) have designed and tested enquiries. During the three-year project (2020-2023) three research questions will be addressed: 1) how the method works as a knowledge-generating approach for students in a Swedish school context, 2) what characterizes teachers’ competence to construct and teach enquiries, and 3) how this competence can be advanced within the framework of a professional learning community.We present the theoretical context for a professional development seminar series called Doing Enquiry, and empirical samples and experiences from its implementation including enquiries designed and performed by the history teachers. Starting from the IDM-framework (Swan, Lee, & Grant, 2018), this seminar series focuses on the collaborative construction of enquiries. A hypothesis for the seminar series was that it would be crucial to provide an opportunity to take the role of the teacher as well as being positioned as a pupil in the construction phase of an enquiry. So far, preliminary results will reflect on the second and third question. The results indicate that some elements in history teachers’ competences, that professional development can enhance, are particularly important, e.g., a systematic approach to the planning, implementation and teaching of an enquiry; using a shared subject didactic knowledge within a professional community; and, deep academic knowledge.

- Angioedema in the mouth or upper airways is a feared adverse reaction to angiotensin-converting enzyme inhibitor (ACEi) and angiotensin receptor blocker (ARB) treatment, which is used for hypertension, heart failure and diabetes complications. This candidate gene and genome-wide association study aimed to identify genetic variants predisposing to angioedema induced by these drugs. The discovery cohort consisted of 173 cases and 4890 controls recruited in Sweden. In the candidate gene analysis, ETV6, BDKRB2, MME, and PRKCQ were nominally associated with angioedema (p < 0.05), but did not pass Bonferroni correction for multiple testing (p < 2.89 × 10-5). In the genome-wide analysis, intronic variants in the calcium-activated potassium channel subunit alpha-1 (KCNMA1) gene on chromosome 10 were significantly associated with angioedema (p < 5 × 10-8). Whilst the top KCNMA1 hit was not significant in the replication cohort (413 cases and 599 ACEi-exposed controls from the US and Northern Europe), a meta-analysis of the replication and discovery cohorts (in total 586 cases and 1944 ACEi-exposed controls) revealed that each variant allele increased the odds of experiencing angioedema 1.62 times (95% confidence interval 1.05-2.50, p = 0.030). Associated KCNMA1 variants are not known to be functional, but are in linkage disequilibrium with variants in transcription factor binding sites active in relevant tissues. In summary, our data suggest that common variation in KCNMA1 is associated with risk of angioedema induced by ACEi or ARB treatment. Future whole exome or genome sequencing studies will show whether rare variants in KCNMA1 or other genes contribute to the risk of ACEi- and ARB-induced angioedema.

- By analyzing e(+)e(-) annihilation data with an integrated luminosity of 2.93 fb(-1) collected at the center-of-mass energy root s = 3.773 GeV with the BESIII detector, we present the first absolute measurements of the branching fractions of twenty Cabibbo-suppressed hadronic D0(+) decays involving multiple pions. The highest four branching fractions obtained are B(D-0 -> pi(+)pi(-)pi(0)) = (1.343 +/- 0.013(stat) +/- 0.016(syst))%, B(D-0 -> pi(+)pi(-)2 pi(0)) = (1.002 +/- 0.019(stat )+/- 0.024(syst))%, B(D-0 -> 2 pi(+)pi(-)pi(0))=(1.165 +/- 0.021(stat) +/- 0.021(sy)(st))%, and B(D+ -> 2 pi(+)pi(-)pi(0)). (1.074 +/- 0.040(stat) 0.030(syst))%. The CP asymmetries for the six decays with highest signal yields are also determined and found to be compatible with zero.

- By using 6.32 fb(-1) of data collected with the BESIII detector at center-of-mass energies between 4.178 and 4.226 GeV, we perform an amplitude analysis of the decay D-s(+) -> K-S(0) pi(+)pi(0) and determine the relative fractions and phase differences of different intermediate processes, which include K-S(0) rho(770)(+), K-S(0)rho(1450)(+), K*(892)(0) pi(+), K* (892)(+) pi(0), and K* (1410)(0) pi(+). With the detection efficiency based on the amplitude analysis results, the absolute branching fraction is measured to be B(D-s(+) -> K-S(0) pi(+) pi(0)) = (5.43 +/- 0.30(stat) +/- 0.15(syst)) x 10(-3).

Tidskriftsartikel (refereegranskat)abstract
- Using 6.32 fb−1 of e+e− collision data collected by the BESIII detector at the center-of-mass energies between 4.178 and 4.226 GeV, an amplitude analysis of the D+s → K0SK−π+π+ decays is performed for the first time to determine the intermediate-resonant contributions. The dominant component is the D+s → K∗(892)+¯K∗(892)0 decay with a fraction of (40.6±2.9stat±4.9sys)%. Our results of the amplitude analysis are used to obtain a more precise measurement of the branching fraction of the D+s → K0SK−π+π+ decay, which is determined to be (1.46±0.05stat±0.05sys)%.

- Using e(+)e(-) annihilation data corresponding to a total integrated luminosity of 6.32 fb(-1) collected at the center-of-mass energies between 4.178 and 4.226 GeV with the BE- SIII detector, we perform an amplitude analysis of the decay D-s(+) -> K-K+pi(+)pi(+)pi(-) and de-termine the relative fractions and phases of different intermediate processes. Absolute branch- ing fraction of D-s(+) -> K-K+pi(+)pi(+)pi(-) decay is measured to be (6.60 +/- 0.47(stat). +/- 0.38(syst).) x 10(-3). The dominant intermediate process is D-s(+) -> a(1) (1260)(+)phi,phi -> K- K+, a(1)(1260)(+) -> rho pi(+), rho -> pi(+)pi(-), with a branching fraction of (5.15 +/- 0.41(stat.) +/- 0.32(syst.)) x 10(-3).

Tidskriftsartikel (refereegranskat)abstract
- Using data collected with the BESIII detector in e(+)e(-) collisions at center-of-mass energies between 4.178 and 4.226 GeV and corresponding to 6.32 fb(-1) of integrated luminosity, we report the amplitude analysis and branching-fraction measurement of the D-s(+) -> pi(+)pi(0)eta' decay. We find that the dominant intermediate process is D-s(+) -> rho(+)eta' and the significances of other resonant and nonresonant processes are all less than 3 sigma. The upper limits on the branching fractions of S-wave and P-wave nonresonant components are set to 0.10% and 0.74% at the 90% confidence level, respectively. In addition, the branching fraction of the D-s(+) -> pi(+)pi(0)eta' decay is measured to be (6.15 +/- 0.25(stat.) +/- 0.18(syst.))%, which receives significant contribution only from D-s(+) -> rho(+)eta' according to the amplitude analysis.
