ePortfolios: models and implementation

This paper explores the use of ePortfolio tools to support teaching, learning and the personal and professional development of postgraduate students at the Institute of Education, University of London (IOE). The needs of tutors and students are considered alongside the affordances and limitations of specific tools in relation to these needs. The study involved five areas of postgraduate study at the IOE, one at PhD level, two at Masters level (MA in ICT in Education and MTeach) and two PGCE courses (PGCE in ICT and Post-Compulsory PGCE). Preliminary discussions with IOE staff revealed five common themes relating to the perceived purpose of an ePortfolio: model, ownership, collaboration, accessibility and support. The first theme relates to the definition of the ePortfolio, whilst the remaining themes address questions relating to ownership, control, use and user needs/development. In this paper, each of the themes and the questions raised within those areas are addressed in detail and a cross-comparative table of responses across each of five teaching scenarios is provided with levels of importance measured on a scale of 1 (low) to 4 (high)

KS3 and KS4 learners' use of Web 2.0 technologies in and out of school - summary

This is a summary of the second report from research commissioned by Becta into Web 2.0 technologies for learning at Key Stages 3 and 4. This report describes findings from data collected using a guided survey of 2,611 Year 8 and Year 10 pupils and 60 focus groups held with approximately 300 learners. The analysis explores learner use of Web 2.0 technologies and their motivations for using social networking sites and the implications of these findings for teachers and providers

Hydrothermal Pre-Treatment Process of Phosphogypsum for Enhanced Rare Earths Recovery

Phosphogypsum (PG) is an industrial waste of phosphoric acid (H3PO4) production from phosphate ore by sulphuric acid (H2SO4) digestion, commonly known as the “wet acid” process. Phosphate rock often contains some valuable rare earth elements (REE) and it is well-established that from 70% to 85% of REE originally present in the phosphate rock end up in the PG, with an average REE content of ~0.4 wt. % [1-4]. PG is considered to be an attractive secondary resource of REE. However, processes available currently for REE recovery are often very expensive, sometimes impractical, and in other cases are characterised by highly variable and low overall REE recoveries due to the complexity of the REE association within the PG structure [5]. Mintek developed a novel hydrothermal process which modifies the microstructure of PG and release entrapped REE phases as shown in Figure 1 for subsequent leaching/recovery. Modification of the PG structure resulted in an increase of REE recovery from 5% (m/m) to 80% (m/m). This process was verified on various PG samples and carries a potential to unlock substantial REE value associated with the enormous size of PG stockpiles globally.
