2371	Khin Sandar Hlaing and Soe Soe Thein	A STUDY OF THE ATTITUDES OF TEACHER EDUCATORS TOWARDS LESSON STUDY USED IN EDUCATION DEGREE COLLEGES	The purpose of this study is to explore the attitudes of teacher educators towards lesson study used in Education Degree Colleges. The quantitative research method was used to study the attitudes of teacher educators towards lesson study. In this study, (200) teacher educators from Education Degree Colleges in Magway Region and Mandalay Region were selected by using a simple random sampling technique. To collect data, the questionnaires were based on the investigation of teachers� perspectives on the lesson study process developed by Wright (2009), the implementation of lesson study program for developing professionalism in teaching profession developed by Copriady (2013), and teachers� viewpoints on the practical implementation of lesson study developed by Haghighiford and Marzbon (2016). Six dimensions were comprised for the questionnaires. Due to the means of six dimensions, teacher educators from the selected Education Degree Colleges were more likely to receive professional development through lesson study but it is necessary to implement lesson study practically in a different way. According to the result, there were no significant differences in the attitudes of teacher educators towards lesson study in Education Degree Colleges in terms of teaching services and qualification. And then, there was a significant difference in the attitudes of teacher educators towards lesson study in Education Degree Colleges in terms of designation. It can be concluded that teachers had positive attitudes towards the different parts of the questionnaires that deal with lesson study. This study can give guidelines for teacher educators to conduct better and more effective teaching and learning process so that student teachers will achieve purposeful learning.	2024

TOWARD LOW-COST, SCALABLE, AND VACUUM FREE PEROVSKITE SOLAR CELLS*	In recent years, lead halide perovskite solar cell efficiency has tremendously reached up to 22.7% due to excellent optoelectronics properties with various fabrication methods. However, stability in ambient air for perovskite solar cells is a lack of effective solution to the problem until now. On the other hand, fabrication processes in a glovebox are strictly limited for large scale production due to high operational costs. Hence, perovskite films are fabricated by two-step deposition method in ambient air relative humidity (RH) of 45 � 5% to acquire high quality films and good crystallization. For the first step, 1 M of lead iodide/N, N-dimethylformamide (PbI2/DMF) solution is deposited on the glass substrate. In a second step, separated amount of 10 to 25 mg of methylammonium iodide (MAI) in 1 ml of isopropanol (IPA) solution is deposited on the PbI2 film. To optimize the highpurity phase, 1% of N, N-dimethylformamide (DMF) is added to MAI/IPA solution. Meanwhile, residual PbI2 peaks transform in the final perovskite films indicate that DMF additive increases the full reaction state of perovskite film. Furthermore, three different annealing times (10, 15 and 30 min) are investigated at 110 ? in air. The highest purity phase achieved for 25 mg/ml (MAI/IPA) increases crystalline size up to 51.8 nm from 35.2 nm (10 mg/ml) analyzed by X-ray diffraction (XRD) and ultraviolet?visible (UV?vis) spectrum exhibits higher absorbance intensity in the longer wavelength as well. Thus, solvent additive method facilitates mass production fabricated in an ambient environment due to increase crystalline growth of perovskite films.	2024

Kinematical analysis is used to perform analysis. The neutral particle emission at point B is checked by two methods and it is observed that the neutral particles are also emitted as the decay products. +7+9+` 7t; possible decay modes are selected by calculating the energy and momentum of decay products and kinematical analysis is done. Masses and binding energies of possible hypernuclei were calculated. According to the analysis result, the event is assigned to be 7,8?Li or 10?Be or ? 14C. The most probable decay mode is identified as 8 ?Li? d +He3+3n with 7641.4?0.006 MeV/c2 mass and 9.65?0.06 MeV binding energy.

The structural characterization of these glass samples has been investigated by using Xray powder diffraction technique (XRD). The morphology of these samples has been determined by using SEM. The transition temperature and crystallization temperature of these glasses were determined by TGA-DTA method. Thermal stability (?T) of the glass samples with the different compositions was identified. The FTIR spectroscopy was also used to study the bonding structure of these glasses in the range from 400 to 4000 cm-1 . It was found that the Bi3+ cations were incorporated in the glass structure as BiO3 and BiO6 units and also boron ions were incorporated as BO3 and BO4 units.	2024

To prepare rice husk ash, the rice husk was treated with dilute hydrochloric acid solution to gain the high percentage silica content and then calcined at 700 �C. The high-quality rice husk ash with acid pretreatment was used as silica source for sodium silica solution to prepare silica gel. The silica gel was prepared by sol gel method with extracted rice husk ash, NaOH and Ca (NO3)2.4H2O. The dried silica gel was calcined at 700 �C and then sintered at 900 �C to obtain glass ceramics. EDXRF was employed to study the chemical purity of the obtained silica. The structure of extracted silica and the phase purity of the prepared samples were identified by X-ray Diffractometer (XRD) analysis and it was found that the sodium calcium silicate phase was appeared. The morphology of the obtained samples was analyzed by Scanning Electron Microscope (SEM) that are depicted as aggregated particles with broad size distribution and the grain size of glass ceramics was 3.6 ?m. Fourier Transform Infrared (FTIR) spectroscopy was used to detect the binding groups in the samples and Si-O-Si stretching mode and sodium calcium silicate phase were observed in both calcined glass powder and glass ceramics.	2024
