Siti Nurma Hanim Hadie Asma’ Hassan Saiful Bahri Talip Muhamad Saiful Bahri Yusoff 《Teacher Development》2019,23(1):36-49
Students’ rating of teacher behaviors provides valuable information on teaching improvement and instructional quality. Unfortunately, there is a lack of new validated instruments for measuring teacher behaviors. The Teacher Behaviors Inventory is an old inventory that was initially developed to measure teaching behaviors as regards lecture-based instructions, which is effected through the use of low-inference items. The aim of this study was to assess its continued suitability in the present educational setting by examining its construct validity and internal consistency through the lens of one lecturer’s teaching behaviors, as rated by 527 students after six interactive lectures. The variables evaluated, as mentioned above, were achieved after an items removal process, which resulted in a 32-item version. Apart from being valid and reliable, this condensed version allows for immediate assessment of teaching behaviors after an instruction session as the rating procedure is now more straightforward and less time-consuming, and also enables a reduction in rating errors. Therefore, the 32-item format serves as a practical diagnostic feedback tool in the present educational arena, permitting a longitudinal teaching behavior assessment to enhance teachers’ professional development. 相似文献

Studies (for example, Dellaportas in Making a difference with a discrete course on accounting ethics. J Bus Ethics 65(4):391–404, 2006; Saat in An investigation of the effects of a moral education program on the ethical development of Malaysian future accountants, 2010) on final year accounting students show that industrial training has a positive impact on the ethical development in a way that students improved in their ethical judgement after attending a 6-month training. Thus, this research aims to evaluate the influence of industrial training in the development of ethical awareness among final year students from a Malaysian public university. These students were from multiple academic backgrounds—engineering, science and social science. A pre and post study was adopted in order to achieve the objectives. A set of survey was distributed to students before and after they have attended industrial training. In assessing students’ ethical awareness, 15 business-related and workplace ethical situations were given and students had to rate their acceptance on these situations from not acceptable (1) to most acceptable (7). From the findings, it can be observed that although the level of ethical awareness among students is fairly good, industrial training has minimal impact in improving or developing students’ ethical awareness. The impact is such because students who undergone industrial training may have observed certain behaviour that they thought are acceptable in a workplace; this may have changed the way students perceived their acceptance on the situations. 相似文献

Energy use in a human community increases to a great extent where these are of a natural population increase. On another hand, technology advances very fast and fuel has an important role in the technological society. Air pollution during burning fuel to create energy forces the human community to look for a new source of energy. The new source must not be finite and must not make air pollution. This source is solar energy. In this educational initiative a model of a solar village, which uses only solar energy, is built. This project turns the school into an agreeable place and makes pupils like to come to it. 相似文献

This paper describes the fabrication of a waveguide and the analysis of its polarization characteristics by applying light-emitting diode （LED） pumping lights to its surface. By using double tubed coaxial line （DTCL） microwave plasma chemical vapor deposition （MPCVD） equipment, an a-Si：H/SiN multilayer waveguide was fabricated whose thickness could be controlled at nanometer order. The main structural material of the waveguide sample consisted of a combination of layers of amorphous silicon hydrogen and silicon nitrate. Once the sample was ready, another major objective of the experiment was to analyze the polarization characteristics of the fabricated waveguide. The idea of the experiment was to analyze how the waveguide reacts when three types of LED （blue, yellow, and red） are radiated onto its surface. The results showed that the fabrication of the a-Si：H/SiN sample is successful. Most effective transmission results, which accord with the polarization characteristics analysis, were obtained. 相似文献

Knowledge management (KM) has often been claimed to be an essential ingredient in building competitive advantage. Yet, KM adoption is relatively slow, especially in the Malaysian context. Most organizations are unsure if the promised performance improvement is just a passing fad. This study intends to provide empirical verifications to support the link between KM practices and performance outcomes for organizations. Responses from 180 knowledge-based organizations were analysed. The analysis indicated that knowledge acquisition and knowledge utilization positively influenced strategic and operational improvement in organizations, whereas the positive effect of knowledge dissemination was only evident in the case of strategic improvement. Organization size had some interesting moderating impact on the tested relationships. 相似文献

IntroductionA specific sequence is recommended for filling blood tubes during blood collection to prevent erroneous test results due to carryover of additives. However, requirement of this procedure is still debatable. This study was aimed to investigate the potassium ethylenediaminetetraacetic acid (K-EDTA) contamination in blood samples taken after a tube containing the additive during routine workflow. The study was also carried out to examine the effect of order of draw on potassium results, regardless of K-EDTA contamination.Materials and methodsIn 388 outpatients, to determine the probability of K-EDTA cross-contamination, blood was drawn sequentially into a serum tube, followed by a tube containing K-EDTA, and by another serum tube. In another 405 outpatients, to evaluate the effect of order of draw blood unrelated to K-EDTA contamination, two serum tube were successively collected. Potassium was measured on Cobas 6000 c501 analyser (Roche Diagnostic GmbH, Mannheim, Germany) by indirect ion selective electrode method.ResultsOf paired samples collected before and after a K-EDTA tube, 24% had a potassium difference of above 0.3 mmol/L. However, no EDTA contamination was detected in these samples as well as 95% confidence intervals (CI) of limits of agreement for calcium were within the allowable error limits based on reference change values. Interestingly, of blood samples drawn successively, 24% had also a difference greater than 0.3 mmol/L for potassium.ConclusionIncorrect order of draw using closed blood collection system does not cause K-EDTA contamination, even in routine workflow. However, regardless of K-EDTA contamination, order of draw has significant influence on the potassium results. 相似文献

This study involved 458 ninth-grade students from two different Arab middle schools in Israel. Half of the students learned science using project-based learning strategies and the other half learned using traditional methods (non-project-based). The classes were heterogeneous regarding their achievements in the sciences. The adapted questionnaire contained 38 statements concerning students’ perceptions of the science classroom climate. The results of the study revealed that students who learned sciences by project-based teaching strategies perceived their classroom learning climate as significantly more Satisfying and Enjoyable, with greater Teacher Supportiveness, and the Teacher–Student Relationships as significantly more positive. The differences between the experimental (project-based learning strategies) and control (non-project) groups regarding their perceptions of the science classroom learning climate could be explained by differences between the two science teaching and learning strategies. 相似文献

Two reef margin species of tropical sea urchins, Echinometra sp. C (Ec) and Echinometra oblonga (Eo), occur sympatrically on Okinawa intertidal reefs in southern Japan. Hybridization between these species was examined through a series of cross-fertilization experiments. At limited sperm concentrations, where conspecific crosses reached near 100% fertilization, both heterospecific crosses showed high fertilization rates (81%–85%). The compatibility of the gametes demonstrated that if gamete recognition molecules are involved in fertilization of these species, they are not strongly species-specific. We found that conspecific crosses reached peak fertilization levels much faster than did heterospecific crosses, indicating the presence of a prezygotic barrier to hybridization in the gametes. Larval survival, metamorphosis, and juvenile and adult survival of hybrid groups were nearly identical to those of their parent species. Hybrids from crosses in both directions developed normally through larval stages to sexually mature adults, indicating that neither gametic incompatibility nor hybrid inviability appeared to maintain reproductive isolation between these species. In adults, Ec×Ec crosses gave the highest live weight, followed by Eo (ova)×Ec (sperm), Ec (ova)×Eo (sperm), and Eo×Eo. Other growth performance measures (viz., test size, Aristotle’s lantern length, and gonad index) of hybrid groups and their parental siblings showed the same trends. The phenotypic color patterns of the hybrids were closer to the maternal coloration, whereas spine length, tube-foot and gonad spicule characteristics, pedicellaria valve length, and gamete sizes showed intermediate features. Adult F1 hybrids were completely fertile and displayed high fertilization success in F1 backcrosses, eliminating the likelihood that hybrid sterility is a postzygotic mechanism of reproductive isolation. Conversely, intensive surveys failed to find hybrid individuals in the field, suggesting the lack or rarity of natural hybridization. This strongly suggests that reproductive isolation is achieved by prezygotic isolating mechanism(s). Of these mechanisms, habitat segregation, gamete competition, differences in spawning times, gametic incompatibility or other genetic and non-genetic factors appear to be important in maintaining the integrity of these species. 相似文献
