Reverse scaffolding

Kiera Chase, Dor Abrahamson
2015 Proceedings of the 14th International Conference on Interaction Design and Children - IDC '15  
We articulated these principles as situated intermediary learning objectives (SILOs).  ...  At each interaction level, the student discovers a SILO, and then the technology takes over by automatizing that SILO, thus freeing the student for further discovery.  ...  We dwell on the construct of a SILO-a situated intermediary learning objective-that we developed as a means of articulating what it is that students learn when they build models of problem situations.  ...

Reverse-scaffolding algebra: empirical evaluation of design architecture

Kiera Chase, Dor Abrahamson
2015 ZDM: Mathematics Education  
We argue for the method's potential via reporting on findings from mixedmethods analyses of a quasi-experimental implementation with 40 students.  ...  We demonstrate our approach by discussing a novel technological learning activity, Giant Steps for Algebra, wherein students construct models of realistic narratives.  ...  We name these emerging principles "situated intermediary learning objectives" (SILOs).  ...

A Proposal to Harmonize BIM and IoT Data Silos using Blockchain Application

Zulkefly Abu Bakar, Malachy Mathews
This paper presents a comprehensive literature review to uncover the current state of BIM and IoT data silos.  ...  However, silos in the BIM and IoT data exchange have impacted the digital process adoption in AECO industry, which aims to change the dynamics and behaviours of the current working process.  ...  Such situation happens because data captured and abstracted from IoT devices and to BIM models at every project stage, whether in the form of files or isolated databases are locked-in silos.  ...

Personal Data Spaces: An Intervention in Surveillance Capitalism?

Tuukka Lehtiniemi
2017 Surveillance & Society  
Personal data spaces, or PDSs, are emerging intermediary services that allow users control over the sharing and use of their data.  ...  PDSs envision their users as data-supplying and benefit-demanding market participants, active subjects in value creation instead of passive objects of data extraction.  ...  As I will discuss below, they have similarities with transparency and open data initiatives in their objective to provide people with new capacities with respect to data.  ...

Machine learning in medicine: should the pursuit of enhanced interpretability be abandoned?

Chang Ho Yoon, Robert Torrance, Naomi Scheinerman
2021 Journal of Medical Ethics  
We argue why interpretability should have primacy alongside empiricism for several reasons: first, if machine learning (ML) models are beginning to render some of the high-risk healthcare decisions instead  ...  For one, how the learned intermediary doctrine would apply in the case of an inherently uninterpretable ML model remains to be mooted.  ...  The verdict of the aforementioned trial, for instance, has since been appealed for a similar repositioning of responsibility towards the healthcare professional as the learned intermediary, duty-bound  ...
