Abstract
AbstractProblem-based learning (PBL) is an instructional strategy that is poised for widespread application in the current, growing, on-line digital learning environment. While enjoying a track record as a defensible strategy in face-to-face learning settings, the research evidence is not clear regarding PBL in on-line environments. A review of the literature revealed that there are few research studies comparing on-line PBL (oPBL) to face-to-face PBL, and, in these, findings have been mixed. This study is a combined meta-analytic and qualitative review of the existing research literature comparing oPBL to face-to-face PBL. The study's aim is to:1. Detect the presence and magnitude of the effectiveness of oPBL;2. Uncover and identify the factors that contribute or explain the effectiveness of oPBL.This review used a mixed methods strategy, combining a meta-analysis with a qualitative analysis of the studies that met inclusion criteria. An overall effect size was found to be slightly in favour of oPBL in terms of student performance outcomes. The qualitative analysis revealed relationships between established concepts of learning. The observations in this systematic review help reduce uncertainty about the robustness of PBL as in instructional strategy delivered in the online environment.ResumeL'apprentissage par problemes (APP), aussi denomme apprentissage par resolution de problemes (ARP), est une strategie pedagogique qui est appelee a se repandre dans l'environnement actuel et toujours croissant de l'apprentissage en ligne. Alors que les evaluations anterieures demontrent que cette strategie est defendable dans les situations d'apprentissage en face a face, les resultats d'etudes scientifiques ne sont pas clairs en ce qui a trait a l'APP dans les environnements en ligne. Une revue de la litterature a revele qu'il y a peu d'etudes qui comparent l'APP en ligne (eAPP) a l'APP en face a face (APP) et que celles qui ont ete realisees arrivent a des resultats mitiges. La presente etude est une revue systematique de la litterature scientifique comparant l'eAPP a l'APP en face a face. Les objectifs de l'etude sont de :1. Deceler la presence et l'ampleur de l'efficacite de l'eAPP;2. Decouvrir et identifier les facteurs qui contribuent ou qui expliquent l'efficacite de l'eAPP.Pour realiser cette revue, nous avons eu recours a une strategie de methodes mixtes, combinant une meta-analyse et une analyse qualitative des etudes qui satisfaisaient aux criteres d'inclusion. Nous avons observe, dans l'ensemble, que l'ampleur de l'effet penchait legerement en faveur de l'eAPP au niveau des resultats de la performance des eleves. L'analyse qualitative a revele des liens entre les concepts d'apprentissage bien etablis. Les remarques formulees dans cette revue systematique aident a reduire l'incertitude au niveau de la robustesse de l'APP en tant que strategie pedagogique utilisee dans un environnement en ligne.IntroductionProblem-based learning (PBL) is an empirically supported instructional strategy in which students are presented with real-life complex problems and are required to generate hypotheses about the causes of the problem and how best to manage it (Barrows, 1998). PBL is distinctive in that the activities are student-centered, as learners assume responsibility for their own learning, and the problems require students be self-directed as they search for the information needed for problem-resolution (Barrows, 1998, 2002). When PBL is implemented in instructional programs, and in particular professional programs, the learning outcomes have been so favourable, that one author has characterized PBL as the most complete and holistic instructional strategy (Margetson, 2000). PBL research increased considerably when there was a flurry of interest to adapt PBL to electronic learning environments (Fischer, Troendle, & Mandl, 2002; Steinkuehler, Derry, Hmelo-Silver, & Delmarcelle, 2002). …

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
