Implications of the Improvement of Teaching Quality for Professional Development (PD) of Academics at the Colleges of Applied Sciences (CASs) in the Sultanate of Oman
No full textThe Oman Accreditation Council (OAC), which is called later the Oman Academic Accreditation Authority (OAAA), designed a higher education institution (HEI) Quality Assurance (QA) framework for Omani public and private Higher Education Institutions (HEIs), starting with a quality audit process in 2008. The Colleges of Applied Sciences (CASs), as a public HEI, are required to ensure the quality of all services and activities to meet particular national standards (specified in the framework) in order to gain a HEI and programme certificate. In line with a quality audit scope, the quality of the fields of PD and related teaching quality should be ensured and enhanced by the promotion and contribution of the former field to the maintenance and improvement of the latter one.
The chief purpose of this study was to identify the uptake and implications of the growing requirement to improve teaching quality and the PD of academics at the CASs in the Sultanate of Oman especially in the context of the application of the QA framework. The study focused on examining the academics’ participation in professional development programmes (PDPs) and current perceptions of PD with respect to the improvement of teaching quality improvement at these colleges. The current study also dealt with a reorganization and prioritization of academics’ PD needs, barriers to effective PD, and factors to enhance PD of academics regarding teaching quality improvement in the colleges.
Based on the purpose and research objectives, the current study adopted both positivist (quantitative) and interpretive (qualitative) research paradigms. Because the study perused quantitative and qualitative data regarding certain variables, it chose a mixed-research design. The researcher designed survey questionnaire to collect quantitative data and a semi-structured interview and a focus group discussion to probe and interpret quantitative findings. After fulfillment of the validity and reliability measurements, a self-completion questionnaire was distributed to a stratified random sample of academics (170) over the six CASs. A total of 150 questionnaires (out of 170) were completed and returned and the response-rate reached 88.2%. The quantitative data was analyzed by appropriate analysis using the Statistical Package for Social sciences (SPSS), while the qualitative data was analyzed by appropriate qualitative analysis.
The findings of the study showed that the level of academics’ participation in PDPs to improve teaching quality in the last two years in the CASs seems to be unsatisfactorily low. The current perceptions of the PD situations in the colleges, relating to teaching quality improvement, signified a shortage in the number of available PDPs and/or a discouragement of academics’ participation in these programmes in the last two years. The study also revealed all the 22 PD needs of academics regarding the improvement of teaching quality are significantly demanded by participants; the higher rated needs focused on a development of ‘student centred’ skills, such as critical thinking and problem-solving skills.
Furthermore, the study illustrated that the highest significant perceived barriers to effective PD in the CASs, as related to teaching quality improvement, focus on a lack of a clear institutional PD policy and a lack of appropriately systematic PD plans. The study also revealed all 10 perceived factors to enhance PD regarding teaching quality improvement are very important. The most significant factors represented and stressed particular problematic issues (the high rated barriers) and a reduction of a heavy workload to enhance academics’ participation in PD regarding the improvement of teaching quality.
Conclusions drawn from the discussion of the findings of study include a lack of a clear PD policy at national and institutional levels and absence of a particular authority/unit concerning PD issues in Omani HEIs. The two problematic issues resulted in a lack of systematic and realistic PD plans in the CASs, involving a lack of academics’ involvement in PD plans, a misconnection of academics’ PD needs to PD, inappropriate facilities and resources allocation, and inappropriate evaluation processes of PD. In addition, the conclusions also include that PD of academics regarding the improvement of teaching quality in the colleges requires more attention and focus to manage particular significant issues perceived by participants as both barriers and potential facilitators relating to PD of academics.
Based on identified conclusions, particular implications for policy and practice to enhance PD to improve teaching quality were set at three levels: governmental, institutional, and individual. Moreover, achievements of the current study according to the research questions were identified and contributions of the study to the fields of PD, teaching quality, and the context of QA and quality audit in HE were addressed. Based on the findings and conclusions, particular directions and recommended issues were suggested to be studied by further research to benefit the enhancement of PD and related teaching quality improvement

Tilman Nagels " ‚Authentizität‘ in der Leben-Mohammed-Forschung". Eine Antwort
No full textThis contribution is a response to Tilman Nagel's essay " ‘Authentizität' in der Leben-Mohammed-Forschung” [‘Authenticity' in the research on the Life of Mohammed] in which the author again presents the main theses argued in his monograph Mohammed. Leben und Legende and responds to criticism. Whereas his critics agree with Nagel that complete ‘authenticity' is unattainable in principle, yet an asymptotic approximation of Mohammed as a figure is indeed possible, the way to attain such an approximation remains a matter of dispute. Contrary to Nagel, the proponents of the so-called isnad-cum-matn analysis hold this method, which offers the possibility to date ḥadīṯs (traditions) and reconstruct texts in circulation in the 1st cent. H., for one of the most successful towards achieving this goal. Another successful procedure of proven value is the evaluation and appraisal of the corpus of traditions traced back to ʿUrwa b. az-Zubayr (d. c. 712), one of the earliest and most important collectors of historical material in Islam. Proponents of both of these procedures do not apply the term ‘authentic', as asserted by Nagel, in the sense of ‘what exactly happened', but rather use this term if the transmitters of a tradition are historical figures and when the process of transmission is proven to have ensued as indicated in the chain of transmissio

Investigation of porous glasses based on sodium-borosilicate glass system
Get PDFThis work investigated the development of porous glasses by making additions of zirconia (ZrO2) and zircon (ZrSiO4) to the sodium borosilicate glass system SiO2-B2O3-Na2O. Additions of Zr-based compounds were made in an attempt to yield more alkaline durable porous glasses compared to the silica-rich porous glass structures of the parent sodium borosilicate glass system. Glasses were fabricated using a high-temperature fusion process. X-ray diffraction (XRD) was used to confirm that the glasses were amorphous upon pouring from the melt. The glasses were characterised using differential thermal analysis (DTA) to identify important thermal events, including the glass transition temperature (Tg) and crystallisation temperature (Tx). The occurrence of amorphous phase separation was key to the formation of two-phase glasses and ultimately porous glasses. It was found that the quantity of sodium oxide (Na2O) in the glass composition played an important role in determining whether phase separation occurred via nucleation and growth or spinodal decomposition. Based on the DTA data, a heat treatment temperature of 650 °C was selected for three different durations (14, 24 and 63 hours). The heat-treatment caused the glasses to phase separate into two phases; a silica-rich phase and a sodium borate phase. The sodium borate phase coarsened as a function of heat-treatment time. Fourier transform infrared (FTIR) spectroscopy, together with XRD, was found to be effective as a means of comparing the phase separation and crystallisation characteristics. Glasses heat-treated for longer times showed some evidence of crystal formation. Having formed two-phase glass, acid leaching was used to remove the borate phase and create a porous structure. The leaching process had to be carefully controlled in terms of acid type, acid concentration, leaching time and leaching temperature. For all glasses, a post-leach alkali wash step was needed to remove trapped silica gel. The porous glasses comprised a silica-rich porous skeleton. Scanning electron microscopy (SEM) revealed classic interconnected porous morphologies. The most consistent and best-defined morphologies were observed for the zircon-containing glass. Energy dispersive X-ray (EDX) analysis confirmed the presence of zirconium (Zr) in the porous silica-rich skeleton. Mercury intrusion porosimetry (MIP) was used to characterise the pore characteristics and measure pore volume, pore size, pore distribution, total pore surface area, and bulk and apparent density. In general, the porous glasses exhibited sharp, unimodal pore distributions, but there was also evidence of micropores, believed due to residual silica gel. Mean pore size ranged from 40 nm to 200 nm for the different porous glasses studied. It was observed that mean pore size linearly increased with square root of the heat-treatment time. Total pore surface area increased with decreasing size of pores and ranged from 5 to 35 m2/g depending on glass composition and heat-treatment time. Alkaline resistance tests were carried out. Zircon- and zirconia-containing porous glasses are 3-4 times more alkali durable than the parent sodium borosilicate glass
Sintering and characterisation of nano-sized yttria-stabilised zirconia
Get PDFA study has been conducted on the pressure-less sintering of the ZrC>2- Y2O3 system that contains 3 mol% Y2O3, and the effect that the temperature / time relationship has on the properties of the final product. Experiments were performed on two types of commercially available, nano-sized, ZrC>2 - 3mol% Y2O3 (3Y-TZP) powders. An unstabilised zirconia powder was also investigated for comparison purposes. Particle size analysis of these powder yield particle sizes ranging from 1.29 |xm to 1.78 pm, suggesting that the particles are heavily prone to agglomeration in water. BET specific surface area analysis showed the powders to be nano-sized as determined using equivalent spherical diameter theory. The density of the powders was measured using helium gas pycnometry. DTA/TGA analysis indicates that binder burnout occurs on heating in the range 300-440°C. Shrinkage and densification rate characteristics of the powders during sintering was investigated using dilatometry. One of the powders demonstrated full shrinkage during isothermal sintering; the other did not. The point of maximum densification rate differed by approximately 100°C for these powders. A dramatic expansion associated with the tetragonal to monoclinic transformation on cooling from 1400°C is observed by dilatometry for unstabilised zirconia powder sample but not for stabilised powder samples. This indicates that the sintered samples retain in tetragonal phase on cooling to room temperature. Pressureless conventional sintering and two-step sintering were used to sinter pressed discs. The density of discs which were sintered across a temperature range of 1350°C to 1550°C varies between 5.72 g/cm3 and 6.03 g/cm3, corresponding to 97.40% and 99.10% of theoretical density respectively. Density as high as 98.85% of theoretical was recorded for twostep sintering applying holding time of 16 h. Vickers hardness values increased with increasing sintering temperature. Fracture toughness measurements were carried out. X-ray diffraction analysis confirmed that sintered discs were fully tetragonal. Microstructural analysis of sintered samples was conducted to assess microstructural changes with respect to sintering temperature
