  Background Diagnostic errors occur frequently, especially in the emergency room. Estimates about the consequences of diagnostic error vary widely and little is known about the factors predicting error. Our objectives thus was to determine the rate of discrepancy between diagnoses at hospital admission and discharge in patients presenting through the emergency room, the discrepancies’ consequences, and factors predicting them. Methods Prospective observational clinical study combined with a survey in a University-affiliated tertiary care hospital. Patients’ hospital discharge diagnosis was compared with the diagnosis at hospital admittance through the emergency room and classified as similar or discrepant according to a predefined scheme by two independent expert raters. Generalized linear mixed-effects models were used to estimate the effect of diagnostic discrepancy on mortality and length of hospital stay and to determine whether characteristics of patients, diagnosing physicians, and context predicted diagnostic discrepancy. Results 755 consecutive patients (322 [42.7%] female; mean age 65.14 years) were included. The discharge diagnosis differed substantially from the admittance diagnosis in 12.3% of cases. Diagnostic discrepancy was associated with a longer hospital stay (mean 10.29 vs. 6.90 days; Cohen’s d 0.47; 95% confidence interval 0.26 to 0.70; P = 0.002) and increased patient mortality (8 (8.60%) vs. 25(3.78%); OR 2.40; 95% CI 1.05 to 5.5 P = 0.038). A factor available at admittance that predicted diagnostic discrepancy was the diagnosing physician’s assessment that the patient presented atypically for the diagnosis assigned (OR 3.04; 95% CI 1.33–6.96; P = 0.009). Conclusions Diagnostic discrepancies are a relevant healthcare problem in patients admitted through the emergency room because they occur in every ninth patient and are associated with increased in-hospital mortality. Discrepancies are not readily predictable by fixed patient or physician characteristics; attention should focus on context.

  Context The ability to self‐monitor one's performance in clinical settings is a critical determinant of safe and effective practice. Various studies have shown this form of self‐regulation to be more trustworthy than aggregate judgements (i.e. self‐assessments) of one's capacity in a given domain. However, little is known regarding what cues inform learners’ self‐monitoring, which limits an informed exploration of interventions that might facilitate improvements in self‐monitoring capacity. The purpose of this study is to understand the influence of characteristics of the individual (e.g. ability) and characteristics of the problem (e.g. case difficulty) on the accuracy of self‐monitoring by medical students. Methods In a cross‐sectional study, 283 medical students from 5 years of study completed a computer‐based clinical reasoning exercise. Confidence ratings were collected after completing each of six cases and the accuracy of self‐monitoring was considered to be a function of confidence when the eventual answer was correct relative to when the eventual answer was incorrect. The magnitude of that difference was then explored as a function of year of seniority, gender, case difficulty and overall aptitude. Results Students demonstrated accurate self‐monitoring by virtue of giving higher confidence ratings (57.3%) and taking a shorter time to work through cases (25.6 seconds) when their answers were correct relative to when they were wrong (41.8% and 52.0 seconds, respectively; p< 0.001 and d > 0.5 in both instances). Self‐monitoring indices were related to student seniority and case difficulty, but not to overall ability or student gender. Conclusions This study suggests that the accuracy of self‐monitoring is context specific, being heavily influenced by the struggles students experience with a particular case rather than reflecting a generic ability to know when one is right or wrong. That said, the apparent capacity to self‐monitor increases developmentally because increasing experience provides a greater likelihood of success with presented problems.

  Background Training in teamwork behaviour improves technical resuscitation performance. However, its effect on patient outcome is less clear, partly because teamwork behaviour is difficult to measure. Furthermore, it is unknown who should evaluate it. In clinical practice, experts are obliged to participate in resuscitation efforts and are thus unavailable to assess teamwork quality. Consequently, we sought to determine if raters with little clinical experience and experts provide comparable evaluations of teamwork behaviour. Methods Novice and expert raters judged teamwork behaviour during 6 emergency medicine simulations using the Teamwork Emergency Assessment Measure (TEAM). Ratings of both groups were analysed descriptively and compared with U and t tests. We used a mixed effects model to identify the proportion of variance in TEAM scores attributable to rater status and other sources. Results Twelve raters evaluated 7 teams rotating through 6 cases, for a total of 84 observations. We found no significant difference between expert and novice ratings for 7 of the 11 items of the TEAM or in the sums of all item scores. Novices rated teamwork behaviour higher on 4 items and overall. Rater status accounted for 11.1% of the total variance in scores. Conclusions Experts’ and novices’ ratings were similarly distributed, implying that raters with limited experience can provide reliable data on teamwork behaviour. Novices show a consistent, but slightly more lenient rating behaviour. Clinical studies and real-life teams may thus employ novices using a structured observational tool such as TEAM to inform their performance review and improvement

  Cross-cultural comparisons of latent variable means demands equivalent loadings and intercepts or thresholds. Although equivalence generally emphasizes items as originally designed, researchers sometimes modify response options in categorical items. For example, substantive research interests drive decisions to reduce the number of item categories. Further, categorical multiple-group confirmatory factor analysis (MG-CFA) methods generally require that the number of indicator categories is equal across groups; however, categories with few observations in at least one group can cause challenges. In the current paper, we examine the impact of collapsing ordinal response categories in MG-CFA. An empirical analysis and a complementary simulation study suggested meaningful impacts on model fit due to collapsing categories. We also found reduced scale reliability, measured as a function of Fisher’s information. Our findings further illustrated artifactual fit improvement, pointing to the possibility of data dredging for improved model-data consistency in challenging invariance contexts with large numbers of groups.

  Does computer programming teach students how to think? Learning to program computers has gained considerable popularity, and educational systems around the world are encouraging students in schools and even children in kindergartens to engage in programming activities. This popularity is based on the claim that learning computer programming improves cognitive skills, including creativity, reasoning, and mathematical skills. In this meta-analysis, we tested this claim performing a 3-level, random-effects meta-analysis on a sample of 105 studies and 539 effect sizes. We found evidence for a moderate, overall transfer effect (g = 0.49, 95% CI [0.37, 0.61]) and identified a strong effect for near transfer (g = 0.75, 95% CI [0.39, 1.11]) and a moderate effect for far transfer (g = 0.47, 95% CI [0.35, 0.59]). Positive transfer to situations that required creative thinking, mathematical skills, and metacognition, followed by spatial skills and reasoning existed. School achievement and literacy, however, benefited the least from learning to program. Moderator analyses revealed significantly larger transfer effects for studies with untreated control groups than those with treated (active) control groups. Moreover, published studies exhibited larger effects than gray literature. These findings shed light on the cognitive benefits associated with learning computer programming and contribute to the current debate surrounding the conceptualization of computer programming as a form of problem solving.

  This article provides an overview of the R package lsasim, designed to facilitate the generation of data that mimics a large scale assessment context. The package features functions for simulating achievement data according to a number of common IRT models with known parameters. A clear advantage of lsasim over other simulation software is that the achievement data, in the form of item responses, can arise from multiple-matrix sampled test designs. Furthermore, lsasim offers the possibility of simulating data that adhere to general properties found in the background questionnaire (mostly ordinal, correlated variables that are also related to varying degrees with some latent trait). Although the background questionnaire data can be linked to the test responses, all aspects of lsasim can function independently, affording researchers a high degree of flexibility in terms of possible research questions and the part of an assessment that is of most interest.

  Participation in international large‐scale assessments has grown over time with the largest, the Programme for International Student Assessment (PISA), including more than 70 education systems that are economically and educationally diverse. To help accommodate for large achievement differences among participants, in 2009 PISA offered low‐performing systems the option of including an easier set of items in the assessment with an aim of providing improved achievement estimates. However, there remains a lack of evidence on the performance of this design innovation. As such, we simulate a design that closely mirrors the PISA 2015 math assessment in order to empirically examine the benefits of including easy items for low‐performing countries. We extend the PISA design to include increased numbers of easy items and items that are easier than currently implemented. Findings show that the current PISA approach provides little advantage compared to a common test for all participants. Our study also demonstrates persistent bias, low coverage rates, and low correlations between generating and estimated proficiency under current designs. Through our simulation we also show that to improve achievement estimation for low performers about half of the items would need to be made significantly easier.

  Hvilke roller har eksamen i norsk grunnopplæring? I Forskrift til opplæringslova framgår det blant annet at eksamenskarakteren skal fastsette kompetansen til eleven ved slutten av opplæringen i faget. Denne artikkelen viser imidlertid at policydokumenter og policyutviklere har en rekke forventninger til hva man skal oppnå ved å ha eksamen og hva man skal kunne benytte eksamensresultater til. I et samspill mellom teori og empiri identifiser artikkelen tre roller for vurdering: å sertifisere, styre og støtte læring og undervisning. Dette begrepsapparatet brukes til å analysere både eksamens formelt definerte formål, og tilsiktede og utilsiktede funksjoner ved eksamenssystemet. Artikkelen baserer seg på tre typer historiske data: (i) Stortingsmeldinger, (ii) Utdanningsdirektoratets årlige rapporter, Utdanningsspeilet, samt (iii) ekspertintervjuer gjennomført i 2013 med en statssekretær og en seniorrådgiver i Kunnskapsdepartementet, og direktøren og en avdelingsdirektør i Utdanningsdirektoratet. I tillegg er det gjort en analyse av gjeldende bestemmelser, slik de kommer til uttrykk i Forskrift til opplæringslova og Rammeverket for eksamen av 2017. Artikkelen avdekker manglende avklaringer av eksamens formål og peker på at dette kan føre til at politikere og andre policyutviklere forvalter og videreutvikler eksamenssystemet på sviktende grunnlag. Videre kan det føre til at Utdanningsdirektoratet, Fylkesmannen og andre tilsynsmyndigheter, skoleeiere, skoleledere, lærere, foreldre og elever bruker eksamensdata på uheldige måter. Artikkelen konkluderer med at lovverk, forskrift og rammeverk for eksamen bør gjennomgås og endres til eksplisitt å uttrykke de rollene eksamen skal fylle og ikke. Slik kan man få et bedre utgangspunkt for å utvikle eksamensprøver og sikre hensiktsmessig bruk av eksamensresultater både nasjonalt og lokalt.

  Artikkelen presenterer de mest sentrale verktøyene for kvalitetsmonitorering som har blitt innført som en del av det «Nasjonale kvalitetsvurderingssystemet for grunnopplæringen» (de nasjonale prøvene, kartleggingsprøvene og elev-undersøkelsen), i all hovedsak ut fra et perspektiv om at dette er målinger som skal bidra med informasjon til skoler, skoleeiere og nasjonale beslutningstakere. Gjennom beskrivelsen legger vi et grunnlag for en drøfting av seks forhold som vi foreslår som spesielt viktige for å videreutvikle det nasjonale kvalitetsvurderingssystemet. Hovedkonklusjonen fra denne drøftingen er at norsk skole har utviklet mange målinger som hver for seg i stor grad har god kvalitet. Det legges imidlertid ikke til rette for en helhetlig analyseramme som gjør det mulig å se de ulike målingene i sammenheng med hverandre, og som i sterkere grad vektlegger et utviklingsperspektiv.

  Likeverd er et viktig aspekt ved norsk skole, og forskjeller i prestasjoner knyttet til hjemmebakgrunn er små i Norge sett i et internasjonalt perspektiv. Likevel er det mye som tyder på at dette kanskje er i ferd med å endres. Denne studien ser på hvordan likeverd har endret seg i løpet av 20 år, og bruker data fra TIMSS (4. og 8. trinn) og PISA (10. trinn) fra 1995 til 2015. Prestasjonsforskjeller mellom skoler (variansen) er stigende gjennom perioden for to av de tre trinnene, men har en nedgang i siste runde i 2015. Samtidig viser det overordnede bildet at spredningen i prestasjoner synker, for så å øke i siste del av perioden. Dersom man sammenligner PISA og TIMSS når det gjelder sammenhengen mellom elevers hjemmebakgrunn og prestasjoner, er ikke mønsteret så tydelig. På 8. trinn i TIMSS har sammenhengen mellom hjemmebakgrunn og prestasjoner på skolenivå doblet seg. Den totale sammenhengen øker kun svakt i TIMSS i perioden, men er uendret i PISA.

Dette kom etter en tilsvarende stor tilbakegang fra 1995 til 2003. I dette kapitlet presenteres en analyse hvor endringen i gjennomsnittlig matematikkskår for 8. trinn fra 2003 til 2015 blir knyttet til endringer for 22 bakgrunnsvariabler. Generelt kan endringer i elevprestasjoner knyttes til flere fundamentalt ulike kilder: Sammensetningen av elevkohortene kan endre seg, undervisningens innhold og kvalitet kan endre seg, og sammenhengene mellom bakgrunnsfaktorer og prestasjoner i matematikk kan endre seg over tid. Gjennom å anvende Oaxaca-Blinder-dekomponering (OBD) kan slike mulige bidrag til framgangen separeres og tallfestes. Analysen gir ikke et entydig bidrag til å forstå den store framgangen. Et funn som kan framheves, er at faktorer knyttet til elevenes selvfølelse og trivsel framstår som viktige.

  I Norge går alle barn født det samme året på samme klassetrinn, med veldig få unntak. Dette betyr at forskjell i alder kan være bortimot tolv måneder på det samme trinnet. I idrett og utdanning viser eksisterende litteratur at generelt presterer de eldste på trinnet vesentlig bedre enn de yngste. Hensikten med denne studien er å bruke norske data fra TIMSS og PISA gjennom 20 år for å se om denne effekten (relativ alderseffekt – RAE) har endret seg over tid, og hvordan den varierer etter klassetrinn og alder. Studien bruker en såkalt regresjons-diskontinuitetsanalyse for å se på effekten over to klassetrinn, og resultatene indikerer at effekten er omtrent 60 % av effekten av et helt skoleår. RAE er to ganger større blant de yngste elevene (4. og 5. trinn) enn de eldste (8. og 9. trinn), men analysene viser at forholdet mellom effekten av et år på skolen og RAE er den samme i begge aldersgruppene. Resultatene er diskutert, og diverse implikasjoner av dem er omtalt.

  TIMSS 1995 kan regnes som den første internasjonale undersøkelsen av sitt slag, og i de mer enn 20 årene som har gått, har vi sett en framvekst av flere og mer varierte internasjonale undersøkelser. I dette kapitlet gir vi en bakgrunn for resten av boka ved å beskrive noen typiske kjennetegn ved de internasjonale undersøkelsene, og vi beskriver hvordan disse undersøkelsene spesielt legger til rette for to typer sammenlikninger – mellom land og over tid; to referanserammer som på hver sine måter gir nyttige linser for å tolke resultater. Vi presenterer også det vi mener er de mest sentrale funnene for norsk skole gjennom disse 20 årene, og på tvers av de ulike undersøkelsene. Sammenlikninger over tid viser at norsk skole har vært preget av en nedgang etterfulgt av en oppgang, og vi ser at læringsmiljø og skoleklima rapporteres å være betydelig bedre enn tidligere. Sammenlikninger med andre viser at norsk skole er preget av relativt små forskjeller: mellom skoler, mellom kjønn (med lesing som unntak) og mellom elever med ulik hjemmebakgrunn. Vi avrunder kapitlet med å foreslå hvordan undersøkelsene kan endre design for å styrke gyldigheten til sammenlikninger innenfor begge disse to referanserammene.

  Background: Progress testing is a longitudinal assessment that aims at tracking students' development of knowledge. This approach is used in many medical schools internationally. Although progress tests are longitudinal in nature, and their focus and use of developmental aspects is a key advantage, individual students’ learning trajectories themselves play, to date, only a minor role in the use of the information obtained through progress testing. Methods: We investigate in how far between-person differences in initial levels of performance and within-person rate of growth can be regarded as distinct components of students’ development and analyze the extent to which these two components are related to performances on national licensing examinations using a latent growth curve model. Results: Both, higher initial levels of performances and steepness of growth are positively related to long-term outcomes as measured by performance on national licensing examinations. We interpret these findings as evidence for progress tests’ suitability to monitor students’ growth of knowledge across the course of medical training. Conclusions: This study indicates that individual development as obtained by formative progress tests is related to performance in high-stakes assessments. Future studies may put more focus on the use of between-persons differences in growth of knowledge.

  This study offers curriculum developers, teachers and science education researchers a fine-grained profile on strengths and weaknesses in specific science domains and topics. The study involved a representative sample of 3844 Norwegian pupils in grade 8. Their responses on 216 TIMSS items in 18 topics from 4 science domains were modelled in a hierarchical item response model. An internal comparison identified topics that were relatively harder or easier compared to other topics for the Norwegian pupils, and an external comparison identified topics that were relatively harder or easier for the Norwegian pupils compared with the average of TIMSS participating countries. Interpretation of the profile necessitates contextualisation; hence, these strengths and weaknesses as well as their plausible explanations and possible implications are discussed from the perspectives of curriculum development, teacher training and science education research.

  Previous studies have assumed a linear relationship between inquiry-based teaching and student achievement in science. However this assumption may be questionable. Recent evidence on the effectiveness of inquiry-based teaching has yielded conflicting findings. To test the linearity assumption, the present study investigated the relation between inquiry-based teaching and achievement by taking into account the possible existence of nonlinear relations using Norwegian TIMSS 2015 data. A multilevel structural equation modeling analysis showed that the relationship was curvilinear. Inquiry-based teaching was positively correlated with achievement, but high frequency of inquiry activities was negatively related to achievement. Furthermore, we found that classroom SES did not affect the strength of the relationship between inquiry and achievement. These findings challenge the linearity assumption and contribute to explaining the conflicting evidence in earlier research as well as promote the effectiveness of inquiry-based teaching regardless of students’ socioeconomic backgrounds.

  Background Fair comparisons of educational systems in large-scale assessments can be made only if the differences in curricula have little impact on the outcomes. This study investigated the sensitivity of science achievement rankings to varying degrees of curriculum implementation in the Trends in International Mathematics and Science Study (TIMSS). Methods Country-specific teacher-reported curriculum implementation profiles across the TIMSS science domains were charted including their within-country variability across the classrooms for 33 participating countries of TIMSS 2015. A sensitivity test compared the original ranking to TIMSS curriculum implementation scenarios (a least-possible, a most-possible, and more realistic country-specific median implementation). Results In contrast to expectations, no support was found for a positive relationship between opportunity to learn and science achievement at the between-country level or the within-country level, with only minor exceptions. The sensitivity analysis under different curriculum implementation scenarios also suggests little impact on the rank order of the countries. Conclusions Plausible explanations for this null finding are addressed; attention and research efforts should focus on improving the quality of curriculum implementation indicators in large-scale assessments.

  Interpersonal trust is associated with a range of adaptive outcomes, including knowledge sharing. However, to date, our knowledge of antecedents and consequences of employees feeling trusted by supervisors in organizations remains limited. On the basis of a multisource, multiwave field study among 956 employees from 5 Norwegian organizations, we examined the predictive roles of perceived mastery climate and employee felt trust for employees' knowledge sharing. Drawing on the achievement goal theory, we develop and test a model to demonstrate that when employees perceive a mastery climate, they are more likely to feel trusted by their supervisors at both the individual and group levels. Moreover, the relationship between employees' perceptions of a mastery climate and supervisor‐rated knowledge sharing is mediated by perceptions of being trusted by the supervisor. Theoretical contributions and practical implications of our findings are discussed.

  The analysis of longitudinal neuroimaging data within the massively univariate framework provides the opportunity to study empirical questions about neurodevelopment. Missing outcome data are an all-to-common feature of any longitudinal study, a feature that, if handled improperly, can reduce statistical power and lead to biased parameter estimates. The goal of this paper is to provide conceptual clarity of the issues and non-issues that arise from analyzing incomplete data in longitudinal studies with particular focus on neuroimaging data. This paper begins with a review of the hierarchy of missing data mechanisms and their relationship to likelihood-based methods, a review that is necessary not just for likelihood-based methods, but also for multiple-imputation methods. Next, the paper provides a series of simulation studies with designs common in longitudinal neuroimaging studies to help illustrate missing data concepts regardless of interpretation. Finally, two applied examples are used to demonstrate the sensitivity of inferences under different missing data assumptions and how this may change the substantive interpretation. The paper concludes with a set of guidelines for analyzing incomplete longitudinal data that can improve the validity of research findings in developmental neuroimaging research.

  This doctoral thesis scrutinizes the content dimension of the Trends in International Mathematics and Science Study (TIMSS) to explore: “What content-specific profiles can we obtain about the students’ strengths and weaknesses, and teachers’ instruction, by disaggregating the test into its items and responses?” and “Why is the relationship between science achievement and teachers’ content coverage seemingly so weak in TIMSS?” Four papers apply advanced analyses of the students’ and teachers’ response-level data in TIMSS 2011 and 2015. Findings suggest variation in the Norwegian pupils’ achievement across science topics compared with the international averages (Paper 1), and the degree of their teachers’ coverage of the topics in class across grades (Paper 2), which can inform educators’ decision-making. Results from instructional sensitivity analyses in TIMSS 2015 in papers 3 and 4 suggest that a finer-grained analysis is required to pick up on instruction when the assessments are remote from the instruction. The indicators for content coverage require further attention as they might not be optimal for their purpose.

  Modern technology permeates almost every area in society and thus necessitates the development of new skillsets--including computer coding. Many leaders around the world consequently encourage students to learn to code, as this may help them to develop other skills, including problem solving, reasoning, and numeracy. The current study, based on a meta-analysis, puts to test this largely accepted claim that learning how to code improves other cognitive skills. We identified 105 relevant studies that examined the transfer of coding skills to other cognitive skills, such as reasoning, problem solving, creativity, literacy, and numeracy. These studies provided more than 150 effect sizes and followed experimental and quasi-experimental designs across all educational levels. A three-level random-effects model was specified to the resultant dataset to summarize the transfer effects. Hedges' g formed the basis for this modelling approach. The aggregated size of the transfer effects--independent of the context of transfer--was positive and mediocre (g = 0.49, 95% CI = [0.37, 0.61]), and showed considerable variation within and between studies. At the same time, this effect differed across transfer contexts--for skills closer to computer coding, effects were larger (near transfer) than for skills that overlap only marginally with coding (far transfer). Moreover, the purpose of coding moderated the overall effects. Our response to the question whether learning to code improves other cognitive skills is positive: Indeed, positive transfer effects can be detected. Nevertheless, learning to code has differential rather than uniform effects on other cognitive skills.
