Analysing tasks for the Flipped Classroom from the perspective of Realistic Mathematical Education

2018

International audience; The advent of Flipped Classroom as a framework for organizing the teaching and learning of mathematics has the potential to revitalize the attention to tasks as a vehicle for meaningful learning in tertiary education. Flipped Classroom is based on the idea of student active learning under close guidance of the university teacher. Due to the possibility to engage the students in meaningful discovery of how mathematics can relate to real-life situations during in-class sessions, the tasks are seen to have a central role in a successful implementation of Flipped Classrooms. This paper explores the realistic mathematics education (RME) as a theoretical framework for task…

How much space for communication is there for a low achieving student in a heterogeneous group ?

2015

International audience; This paper reports on a case study aiming to deepen our understanding of low achieving students' learning of algebra, in particular when they work with pattern problems. We observed one low achieving student, May, who participated and worked in three different heterogeneous settings. Data were analysed from a multimod-al perspective on key and regulating activities in the groups. The analysis revealed that May's contribution varied, depending on the composition of the groups, and that her contributions were influenced by regulating activities by peers and access to physical artefacts. The findings show that a low achieving student is able to generalise beyond her ari…

Determining your own grade – Student perceptions on self-assessment in a large mathematics course

2018

International audience; In our poster, we report on students' perceptions on self-assessment in large undergraduate course context taught with the DISA model (Digital Self-Assessment) in which the final exam is replaced by self-assessment. The students found that practising self-assessment skills was valuable and encouraged them to study for themselves. At the same time, self-assessment was considered unfamiliar and therefore difficult. We argue that the DISA model encouraged students to take more responsibility on their own learning.

The genus Ruppia L. (Ruppiaceae) in the Mediterranean region: An overview

2015

Abstract This paper reviews the current knowledge on the diversity, distribution and ecology of the genus Ruppia L. in the Mediterranean region. The genus Ruppia, a cosmopolitan aquatic plant complex, is generally restricted to shallow waters such as coastal lagoons and brackish habitats characterized by fine sediments and high salinity fluctuations. In these habitats Ruppia meadows play an important structural and functional role. Molecular analyses revealed the presence of 16 haplotypes in the Mediterranean region, one corresponding to Ruppia maritima L., and the others to various morphological forms of Ruppia cirrhosa (Petagna) Grande, all together referred to as the “R. cirrhosa s.l. co…

Glioblastoma: development of new diagnostic tools based on EV-associated proteins

2021

Glioblastomas multiforme (GBM) are the most common malignant primary brain tumors in adults. They are highly aggressive and have an overall survival of <15 months despite maximal surgical resection and chemoradiation (Ostrom, 2019). GBMs are typically heterogeneous with a wide range of genetic and epigenetic variations among tumor cells. Extracellular vesicles (EVs) represent one of the plausible ways through which can be obtained a better understanding of the heterogeneous subpopulations of GBM / molecular signatures. EVs hold promise for the discovery of potential tumours biomarkers useful in clinical managment for GBM patient diagnosis and follow-up. Isolating EVs from body fluids and sc…

Trademarks recognition based on local regions similarities

2010

This paper deals with content based image retrieval. We propose a logo recognition algorithm based on local regions, where the trademark (or logo) image is segmented by the clustering of points of interest obtained by Harris corners detector. The minimum rectangle surrounding each cluster is detected forming the regions of interest. Global features such as Hu moments and histograms of each local region are combined to find similar logos in the database. Similarity is measured based on the integrated minimum average distance of the individual components. The results obtained demonstrate tolerance to logos distortions such as rotation, occlusion and noise.

Coherent states: a contemporary panorama

2012

Coherent states (CS) of the harmonic oscillator (also called canonical CS) were introduced in 1926 by Schr?dinger in answer to a remark by Lorentz on the classical interpretation of the wave function. They were rediscovered in the early 1960s, first (somewhat implicitly) by Klauder in the context of a novel representation of quantum states, then by Glauber and Sudarshan for the description of coherence in lasers. Since then, CS have grown into an extremely rich domain that pervades almost every corner of physics and have also led to the development of several flourishing topics in mathematics. Along the way, a number of review articles have appeared in the literature, devoted to CS, notably…

Exploration of new post-secondary mathematics teachers' experiences: preliminary results of a narrative inquiry

2018

International audience; This paper reports on a pilot study that has taken place during the winter semester of 2017, for a larger project whose goal is to understand the process of becoming a mathematics teacher at post-secondary level. With very few information from the literature on this process at this specific level, this pilot study acts as an exploration of the issues and reality the new teachers face. To do so, we conducted a narrative inquiry with three new post-secondary mathematics teachers who were interviewed on a regular basis during a semester. Those interviews provided an insight into the new teachers' experiences by pointing out themes that are relevant to them. We also came…

Tasks for enriching the understanding of the concept of linear span

2018

International audience; The concept of linear span is one of the first abstract notions that students encounter in a course on Linear Algebra. Using the theoretical construct of concept image and concept definition (Tall & Vinner, 1981) along with observations about teaching and learning Linear Algebra, we present two tasks designed to enrich students' concept image regarding linear span. These tasks could be included in a problem workshop of an introductory university course on Linear Algebra. Each task is carefully created and/or selected so as to foster the ground for potential conflict factors to arise and be confronted. A preliminary evaluation shows that the tasks are well received by…
