‘The idea is nice… but not for me’: First-year students’ readiness for large-scale ‘flipped lectures’—what (de)motivates them?

Higher Education - The flipped classroom is proposed as an answer to challenges in higher education. However, studies that explore its influence on first-year student motivation are largely...

Development and validation of a low cost blood filtration element separating plasma from undiluted whole blood

Clinical point of care testing often needs plasma instead of whole blood. As centrifugation is labor intensive and not always accessible, filtration is a more appropriate separation technique. The complexity of whole blood is such that there is still no commercially available filtration system capable of separating small sample volumes (10-100 μl) at the point of care. The microfluidics research in blood filtration is very active but to date nobody has validated a low cost device that simultaneously filtrates small samples of whole blood and reproducibly recovers clinically relevant biomarkers, and all this in a limited amount of time with undiluted raw samples. In this paper, we show first that plasma filtration from undiluted whole blood is feasible and reproducible in a low-cost microfluidic device. This novel microfluidic blood filtration element (BFE) extracts 12 μl of plasma from 100 μl of whole blood in less than 10 min. Then, we demonstrate that our device is valid for clinical studies by measuring the adsorption of interleukins through our system. This adsorption is reproducible for interleukins IL6, IL8, and IL10 but not for TNFα. Hence, our BFE is valid for clinical diagnostics with simple calibration prior to performing any measurement.     

Pre-university Chemistry Students in a Mimicked Scholarly Peer Review

Peer review is a significant component in scientific research. Introducing peer review into inquiry processes may be regarded as an aim to develop student understanding regarding quality in inquiries. This study examines student understanding in inquiry peer reviews among pre-university chemistry students, aged 16–17, when they enact a design of a mimicked scholarly peer review. This design is based on a model of a human activity system. Twenty-five different schools in Brazil, Germany, Poland and The Netherlands participated. The students (n?=?880) conducted in small groups (n?=?428) open inquiries on fermentation. All groups prepared an inquiry report for peer review. These reports were published on a website. Groups were randomly paired in an internet symposium, where they posted review comments to their peers. These responses were qualitatively analyzed on small groups’ level of understanding regarding seven categories: inquiry question, hypothesis, management of control variables, accurate measurement, presenting results, reliability of results, discussion and conclusion. The mimicked scholarly review prompted a collective practice. Student understanding was significantly well on presenting results, discussion and conclusion, and significantly less on inquiry question and reliability of results. An enacted design, based on a model of a human activity system, created student understanding of quality in inquiries as well as an insight in a peer-reviewing practice. To what extent this model can be applied in a broader context of design research in science education needs further study.     

The transparent self

This paper critically engages with new self-tracking technologies. In particular, it focuses on a conceptual tension between the idea that disclosing personal information increases one’s autonomy and the idea that informational privacy is a condition for autonomous personhood. I argue that while self-tracking may sometimes prove to be an adequate method to shed light on particular aspects of oneself and can be used to strengthen one’s autonomy, self-tracking technologies often cancel out these benefits by exposing too much about oneself to an unspecified audience, thus undermining the informational privacy boundaries necessary for living an autonomous life.     

Profiles of learning opportunities of multilingual and monolingual children in kindergarten

Early childhood education serves an increasing number of multilingual children, and teachers are challenged to create high-quality learning opportunities in the classroom for all children. The child’s engagement and interactions with the teacher are important in this respect. The present study therefore examined how multilingualism relates to engagement and teacher-child interactions, taking a person-oriented approach. During one school year, 76 kindergarteners (43 multilingual) from 19 classrooms were observed for behavioral engagement and individual teacher-child interactions. Five engagement profiles were identified that reflect different levels of engagement across classroom settings. Multilingual children were overrepresented in profiles that showed lower engagement in one or more settings. Also, five interaction profiles were identified that showed strong diversity in the interactions of teachers with children in their classroom. Monolingual and multilingual children were equally represented across these profiles. Children in the more beneficial interaction profiles were also often in the moderate-to-high engagement profiles.
