Adopting a student-led pedagogic approach within higher education: The reflections of an early career academic

The current paper presents a reflective account of the adoption of a student-led pedagogic approach, based upon the first author’s experiences of working within a new academic institution. Carl Rogers’ writings around student-centred learning and the role of the facilitator provide the theoretical underpinning for the reflections put forward, and contextual information regarding the institution’s learning and teaching strategy, and the first author’s teaching background are also provided. Observations and reflections relating to ‘power’ within teaching and learning, and the challenges (and successes) encountered when adopting the role of a ‘facilitator of learning’ are considered from a critical standpoint. The paper closes with some key questions and considerations surrounding the first author’s ongoing exploration of this innovative pedagogic approach

Wearable Posture Identification System for Good Sitting Position

Every human spends most of their time remain seated especially students. A good posture during seated is important to determine the human health, while a bad posture during seated posture can lead to numerous diseases. This paper explained the design and development of wearable posture identification system using accelerometers to determine the good human posture in a seated position. Two accelerometers were used to determine the posture of an individual. The first accelerometer was placed on the human lumbar spine while the second accelerometer was placed on the human cervical spine. The calculation of the angle in determining the posture was processed using Arduino. There is three experiment was conducted: calibration test, performance measurement test and real-time analysis test. The calibration test was conducted to determine the percentage error of the accelerometer when compared with goniometer at static condition. The second experiment was conducted to determine the percentage error of between accelerometer and electrogoniometer at the dynamic condition. The third experiment was conducted to test the accelerometer in real life environment. The result showed that accelerometer has the percentage error less than 3% when compared to goniometer and electrogoniometer. This system can monitor and identify the good and bad sitting posture

Dilemmas in doing insider research in professional education

This article explores the dilemmas I encountered when researching social work education in England as an insider researcher who was simultaneously employed as an educator in the host institution. This was an ethnographic project deploying multiple methods and generating rich case study material which informed the student textbook Becoming a Social Worker the four-year period of the project. First, ethical dilemmas emerged around informed consent and confidentiality when conducting surveys of students and reading their portfolios. Second, professional dilemmas stemmed from the ways in which my roles as a researcher, academic tutor, social worker and former practice educator converged and collided. Third, political dilemmas pertained to the potential for the project to crystallize and convey conflicts among stakeholders in the university and community. Since the majority of research in social work education is conducted by insiders, we have a vital interest in making sense of such complexity

Effect of varying acid hydrolysis condition in Gracilaria sp. fermentation using sasad

Macroalgae or seaweed is being considered as promising feedstock for bioalcohol production due to high polysaccharides content. Polysaccharides can be converted into fermentable sugar through acid hydrolysis pre-treatment. In this study, the potential of using carbohydrate-rich macroalgae, Gracilaria sp. as feedstock for bioalcohol production via various acid hydrolysis conditions prior to the fermentation process was investigated and evaluated. The seaweed used in this research was from the red algae group, using species of Gracilaria sp. which was collected from Sg. Petani Kedah, Malaysia. Pre-treatment of substrate was done using H2SO4 and HCl with molarity ranging from 0.2M to 0.8M. The pretreatment time were varied in the range of 15 to 30 minutes. Fermentation was conducted using Sasad, a local Sabahan fermentation agent as a starter culture. Alcohol extraction was done using a distillation unit. Reducing sugar analysis was done by Benedict test method. Alcohol content analysis was done using specific gravity test. After hydrolysis, it was found out that acid hydrolysis at 0.2M H2SO4 and pre-treated for 20 minutes at 121°C has shown the highest reducing sugar content which has yield (10.06 mg/g) of reducing sugar. It was followed by other samples hydrolysis using 0.4M HCl with 30 minutes pre-treatment and 0.2M H2SO4, 15 minutes pre-treatment with yield of 8.06 mg/g and 5.75 mg/g reducing sugar content respectively. In conclusion, acid hydrolysis of Gracilaria sp. can produce higher reducing sugar yield and thus it can further enhance the bioalcohol production yield. Hence, acid hydrolysis of Gracilaria sp. should be studied more as it is an important step in the bioalcohol production and upscaling process
