Professional characteristics of an educator: A survey of literature

Abstract

Literature has shown that various studies have dealt with different professional features of teaching and they have focused on one or few professional characteristics of educators. In spite of the immense amount of literature on educator characteristics, a comprehensive study that would encompass the vital professional characteristics of an educator in total is lacking. This has instigated the researcher to take up the study to identify the professional characteristics of an educator. An attempt was made in identifying the educators' characteristics using student outcome as a boundary criterion to select the characteristics from among several that are available in the literature. Therefore, a new model of professional characteristics of educators was proposed. This paper discusses in detail, the characteristics of a profession in general and the wide range of educator’s characteristics as studied in previous researches. The paper presents a wide scope for the models developed to be studied in depth to appreciate and investigate more about the professional characteristics identified through this review of literature. The models may also be tested empirically for further accumulation of knowledge in the field.

Structural characterization, catalytic, kinetic and thermodynamic properties of Aspergillus oryzae tannase

“…oryzae tannase recorded in the present study (2453.9 U/mg protein) was higher than the value recently reported by other investigators (6.0 U/mg protein) [20], 209 U/mg protein, [21], 950.6 U/mg protein, [5] , 0.295 U/mg protein , [22], and 79.7 U/mg protein [7].…”

“…A. oryzae tannase exhibited k cat, , Vmax/Km, Kcat/Km, values of 551.4 s -1 , 849.15 (U/mg protein/mM) and 133.5 (mM -1 s -1 ) respectively (Table 3). These values are quit higher than recently reported values for P. herquei [11], and Mucor sp [5]. The calculated values of thermodynamic parameters for tannic acid hydrolysis, i.e., the enthalpy of activation (ΔH*), Gibbs free energy (ΔG*), and entropy of activation (ΔS*) were 30.02 kJ mol −1 , 59.75 kJmol −1 , and −95.90 J mol −1 K −1 , respectively ( Table 3).…”

“…Tannase from A. oryzae was purified to 36.7 folds with a recovery of 15.8% of the original activity (Table 1). Lower purification-fold was reported for other purified tannases from Rhodococcus NCIM 2891(2.33-fold) [20], Aspergillus tamarii (7.17-fold) [21] Mucor sp (12.25-fold) [5] and Aspergillus ficuum Gim 3.6 (2.74-fold) [8]. Furthermore, the specific activity of the pure A.…”

Pengembangan Profesionalitas Guru dalam Memahami Karakter Siswa Sekolah Dasar

“…Para ahli telah menjelaskan bahwa guru professional adalah guru yang mampu menguasai karakteristik siswa dari segi fisik, emosional, hingga kendala belajar yang dialami oleh setiap anak (Anitha & Krishnaveni, 2013). Pernyataan tersebut adalah benar dan setiap guru wajib memiliki kemampuan untuk memahami karakteristik siswa namun tidak hanya dalam segi fisik dan emosional tetapi diharapkan guru juga mampu menganalisis serta mencari cara atas tindakan yang tepat untuk mengatasi kesulitan belajar siswa.…”
