This report presents early findings from a demonstration and random assignment evaluation of two supplemental literacy programs that aim to improve the reading comprehension skills and school performance of struggling ninth-grade readers. On average, the programs produced a positive, statistically significant impact on reading comprehension among students

The Enhanced Reading Opportunities Study: Findings from the Second Year of Implementation

According to the National Assessment of Educational Progress, a majority of ninth-graders in low-performing high schools begin their freshman year with significant reading difficulties. Poor reading ability is a key predictor of academic disengagement and, ultimately, dropping out. This report presents findings from the second year of the Enhanced Reading Opportunities (ERO) study, a demonstration and random assignment evaluation of two supplemental literacy programs -- Reading Apprenticeship Academic Literacy and Xtreme Reading -- that aim to improve the reading comprehension skills and school performance of struggling ninth-grade readers

What are the characteristics of a good teacher?

This paper presents the findings of a study conducted in 2011 with the students studying English at the School of Languages at Sabanci University (SU) and the participants (English teachers, academicians, and English teacher candidates) who attended our presentation “what are the characteristics of a good teacher?” presented at the 15th International INGED Conference, “Taking it to the Limits” held on 20 October, 2011 on their perceived characteristics of the exemplary teacher. The idea to conduct such a study came about upon observation of teachers’ unease about the evaluation forms that students complete at the end of each semester. Teachers’ perceptions of effective teaching seemed to differ from those of students. Therefore, we decided to prepare various instruments to identify and measure students’ perceptions of the characteristics of exemplary language teachers and teachers’ perceptions of the characteristics of the exemplary language teacher and compare the results. In light of this aim, 31 intermediate 1 and 2 level students were asked to provide a written response to the prompt “Describe your perception of the good English teacher” to explore the characteristics they find exemplary in their (past and present) language teachers’ teaching practices. The participants attending our session at the INGED conference were also presented the same prompt at the beginning of our presentation and asked for a written response. The participants kept their responses until the end of the presentation in case they wanted to make any changes or additions. We hope that the findings in this paper encourage teachers to ‘re-contemplate’ their own teaching methodology and its impacts on students’ learning processes, and, if necessary, make changes to their teaching to promote students’ language competence and performance

Useful Descriptions of Organizational Processes: Collecting Data for the Process Handbook

This paper describes a data collection methodology for business process analysis. Unlike static objects, business processes are semi-repetitive sequences of events that are often widely distributed in time and space, with ambiguous boundaries. To redesign or even just describe a business process requires an approach that is sensitive to these aspects of the phenomena. The method described here is intended to generate semi-formal process representations suitable for inclusion in a "handbook" of organizational processes. Using basic techniques of ethnographic interviewing and observation, the method helps users map decomposition, specialization, and dependency relationships at an intermediate level of abstraction meaningful to participants. By connecting new process descriptions to an existing taxonomy of similar descriptions in the Handbook, this method helps build a common vocabulary for process description and analysis.

Removal of As(III) and As(V) from water using green, silica-based ceramic hollow fibre membranes via direct contact membrane distillation

Arsenite [As(III)] and arsenate [As(V)] removal by direct contact membrane distillation (DCMD) using novel hydrophobic green, silica-based ceramic hollow fibre membranes derived from agricultural rice husk was investigated in this work. The green ceramic hollow fibre membranes were prepared from amorphous (ASHFM) and crystalline (CSHFM) silica-based rice husk ash and modified to be hydrophobic via immersion fluoroalkylsilane (FAS) grafting of 1H,1H,2H,2H-perfluorodecyltriethoxysilane. Superhydrophobic contact angle values up to 157° and 161° were obtained for ASHFM and CSHFM, respectively. Remarkably, the membrane surface morphology mimicked a look-alike lotus-leaf structure with decrement in pore size after grafting via the silane agent for both membranes. The effect of arsenic pH (3–11), arsenic concentration (1–1000 ppm) and feed temperature (50–80 °C) were studied and it was found that feed temperature had a significant effect on the permeate flux. The hydrophobic CSHFM, with a flux of 50.4 kg m−2 h−1 for As(III) and 51.3 kg m−2 h−1 for As(V), was found to be the best of the tested membranes. In fact, this membrane can reject arsenic to the maximum contaminant level (MCL) limit of 10 ppb under any conditions, and no swelling mechanism of the membranes was observed after testing for 4 hours

Over the years, many methods and techniques have been proposed to improve their elicitation, documentation, and validation. Knowing more about the state of the practice on these topics may benefit both practitioners' and researchers' daily work. A few empirical studies have been conducted in the past, but none under the perspective of software architects, in spite of the great influence that NFRs have on daily architects' practices. This paper presents some of the findings of an empirical study based on 13 interviews with software architects. It addresses questions such as: who decides the NFRs, what types of NFRs matter to architects, how are NFRs documented, and how are NFRs validated. The results are contextualized with existing previous work.Peer ReviewedPostprint (author’s final draft

Characterization of amorphous silica and crystalline silica from rice husk ash on water filtration application

The presence of water pollution which consists of heavy metals, fecal and others has produced a major problem. These can lead the water to the toxicity and the impurity of water will be disrupted. Therefore, it would not be safe to drinks and could be threatening to live health. In addition, the current market now is dealing with high-cost production to develop ceramic membranes and has been using expensive material to make the filtration system works. In order to challenge the issue, the preparation of ceramic water filtration at low-cost production and using an effectively silica from natural waste rice husk was evaluated. Rice husk was fired at 700ºC and 1000ºC respectively and produced rice husk ash which mutated to amorphous and crystalline silica. Five samples were fabricated after been mixed with the compositions of rice husk ash, kaolin clay, and wheat flour, used at 40:40:20 ratios by weight respectively. The fabrications of the ceramic membrane were conducted by using dry pressing. The samples then were dried in the oven at 60ᵒC for 1 hour followed by sintering at 1000ᵒC respectively. These samples (OO, C1, C2, N1, and N2) were tagged based on unwashed and washed material with the chemical. The properties of silica which are the microstructure and pore size, from rice husk ash were obtained by using Scanning Electron Microscopy (SEM), X-Ray Fluorescence (XRF) and x-ray diffractometer (XRD). Effect of silica content in ceramic filtration membrane was investigated and characterized in term of porosity, density, water absorption, membrane hardness, pore size, flow rate, the turbidity of water (before and after filtration) and pH value. From the result, sample C2 was the best option to support the objective by 98.60% silica content, 64.82% of porosity, 1.1433 mg/cm3 of density, 40.59% of water absorption, 171.0 Hv of hardness, 0.177 l/hr of flowrate and pH of 7.62 of water after filtration. In general, the quality of the ceramic filter membrane is reliant on the raw material, while the flow rate and water clarity are dependent on the pore size of the filter membrane

Creativity and Art Education: Gaps Between Theories and Practices

Theories of creativity from different disciplines map onto teaching strategies within the fine art field. In particular, the outcomes of historical studies by psychologists and experimental studies within cognitive science have significant resonance with some long-standing methods of teaching artists. Through a series of interviews with experienced teachers of studio art in the UK university context, and analysis of written material to support teaching, this paper recognizes the need for a more systematic exploration of how creative thinking may have been embedded in the teaching of artists. We identify the presence of practical strategies, field knowledge, artistic identity, and the importance of ‘space’ within the accounts of teaching and the documents considered. We note that notions of identity and space are not clearly present within existing models of creativity, but aspects of them reflect tolerance for ambiguity. We conclude by reflecting that this space within conceptions of fine art education is a gap that needs attention and that the field that generates the creative practitioners of the future should understand creativity

Early education pilot for two year old children : evaluation

This report provides the findings of the evaluation of the early education pilot for disadvantaged two year old children (the pilot). This study aimed to assess the impact of the pilot by looking at: how well the pilot was targeted, parents’ experiences of taking up a pilot place, the quality of the pilot settings, the impact on the children’s behaviour, and parents’ views and experiences of using a pilot place. The pilot provided free early years education to over 13,500 disadvantaged two year olds between 2006 and 2008. The main purpose of the pilot was to improve children’s social and cognitive outcomes, e.g. their social confidence and independence, and their verbal skills and reasoning ability. Additional aims were to have a positive impact on children’s parents and wider family e.g. on the relationship between parents and their children, or on parent’s emotional wellbeing. The funding offered these children 7.5 or in a small number of local authorities 12.5 hours of early years education per week for 38 weeks of the year. The pilot places were available in a variety of early years settings e.g. nurseries, play groups and with childminders, but all were required to operate the Birth to Three Matters curriculum.© National Centre for Social Research 2009.
