Kesan latihan dalam perkhidmatan ke atas kualiti pengajaran dam pembelajran dalam bidang teknik dan vokasional

Kajian ini bertujuan untuk mengenalpasti keberkesanan latihan dalam perkhidmatan yang dihadiri oleh guru-guru teknik dan vokasional dan sejauh mana hubungannya dengan keberkesanan pengajaran mereka dan pencapaian pelajar. Kajian ini merupakan kajian kuantitatif yang turut disokong dengan maklumat daripada data kualitatif. Maklumat dikumpulkan melalui dua set soal selidik, set A dan set B. Set A diberikan kepada 43 orang guru sekolah menengah teknik (SMT) di Kluang, Batu Pahat, Muar, Segamat dan Pontian, Johor. Kajian ini mempertimbangkan empat mata pelajaran elektif utama bagi pelajar-pelajar aliran teknikal iaitu Pengajian Kejuruteraan Awam (PKA), Pengajian Kejuruteraan Mekanikal (PKM), Pengajian Kejuruteraan Elektrik (PKE) dan Lukisan Kejuruteraan (LK). Antara maklumat yang diperolehi adalah latar belakang responden, keberkesanan latihan yang diikuti dan juga keberkesanan pengajaran guru. Manakala soal selidik set B pula diedarkan kepada 1225 orang pelajar yang diajar oleh guru-guru di atas. Maklumat mengenai keberkesanan guru-guru teknik dan vokasional pada pandangan pelajar diperoleh melalui soal selidik ini. Kaedah temu bual telah dilakukan ke atas Penolong-penolong Kanan SMT untuk mendapatkan maklumat umum daripada pihak pengurusan yang boleh membantu kajian. Di samping itu, data markah peperiksaan pelajar juga diambil dan dianalisis. Semua data telah dianalisis menggunakan pakej SPSS versi 12. Antara analisis yang dilakukan adalah taburan kekerapan bagi data latar belakang responden, nilai purata bagi data latihan dalam perkhidmatan dan guru berkesan, ujian-? untuk mengkaji perbezaan pencapaian pelajar yang diajar oleh guru yang mengikuti latihan dan tiada latihan dalam perkhidmatan dan pekali korelasi Pearson bagi mengkaji hubungan antara latihan dalam perkhidmatan dengan keberkesanan pengajaran guru dan pencapaian pelajar. Kajian membuktikan bahawa latihan dalam perkhidmatan yang dihadiri oleh guru SMT mempunyai tahap keberkesanan yang tinggi. Latihan dalam perkhidmatan yang menitikberatkan kemahiran guru menjadi ciri utama yang dipersetujui oleh para guru di SMT. Namun begitu, ada juga aktiviti-aktiviti pembangunan staf bagi guru-guru teknikal yang dilaksanakan secara kurang berkesan dari segi tempoh yang tidak mencukupi dan perlaksanaan yang tidak berterusan. Kajian juga membuktikan bahawa guru-guru SMT mempunyai kecekapan profesion yang tinggi dari segi kemahiran dan ilmu pengetahuan tetapi tahap keberkesanan sederhana dari segi hubungan interpersonal dan kemahiran kaunseling. Kajian mendapati terdapat hubungan yang signifikan di antara latihan dalam perkhidmatan dengan keberkesanan pengajaran guru, keberkesanan pengajaran guru dengan pencapaian pelajar dan juga antara latihan dalam perkhidmatan dengan pencapaian pelajar

Comparative study of nanorods and nanoflowers TiO2 thin film for heterostructure application

This study introducesn-type nanorods and nanoflowers TiO2/p-type Cu2O thin film where the modification of the heterostructure between these two materials is believed to enhancethe conversion efficiencyin solar cell application.The nanorods and nanoflowers structure areexpected to improve the solar cell performance by providing better electron mobility and high specific surface area to deposit more Cu2O material for light radiation absorption.Besides, the structures were chosen due to their simple method of preparation and enhance efficiency in various applications.The n- type TiO2 thin filmswere produced using a hydrothermal method with some fabrication parameters studied during the preparation of TiO2 thin films such as Titanium Butoxide (TBOT) concentrations involving 0.07, 0.09, 0.11, 0.13 and 0.15 M. Another parameter is the duration of hydrothermal to obtain the optimum TiO2 which covered 7, 10, 13 and 16 hours of fabrication process. Next, the Cyclic Voltammogram (CV) measurement was carried out to identify the deposition parameter of p-Cu2O on TiO2/FTO substrate. Correspond to the CV measurement, -0.4V vs Ag/AgCl of potential deposition were used to develop p-Cu2O on the TiO2 layer. The construction of heterostructure was done through electrodeposition of p-Cu2O by using copper acetate based solution with pH value 12.5 at bath temperature of 60°C. The structural, morphological, optical, topological and electrical properties, were evaluated by using X-ray (XRD), Field Emission-Scanning Electron Microscopy (FE-SEM), Ultra Violet-Visible (UV-Vis), Atomic Force Microscopy (AFM) and Four-Point Probe, respectively. The TiO2 thin film exhibitsan optimum parameter at 10 hours duration of the hydrothermal process with the concentration of TBOT used was 0.9M. At the end of this study, the heterostructure thin film was successfully fabricated with a power conversion efficiency of 2x10-4%. Although low efficiency was obtained in this study, however, this finding might open a new door to the enhancement of TiO2 base for heterostructure application such as this heterojunction solar cell

Simulation of 1 x 2 OTDM router employing symmetric Mach-Zehnder switches

In high-speed all-optical time division multiplexed (OTDM) routers it is desirable to carry out data routing, switching, clock recovery and synchronisation in the optical domain in order to avoid the bottleneck due to optoelectronics conversion. The authors propose an optical switch based on all-optical symmetric Mach–Zehnder (SMZ) switching and investigate its characteristics. The proposed switch is to be used as a building block for a simple 1x2 OTDM router for asynchronous OTDM packet routing, where clock recovery, address recognition and payload routing are all carried out in the optical domain. Simulation and numerical results demonstrate that clock recovery, address recognition and payload routing are possible with small amounts of crosstalk. Also presented are simulation results for bit error rate (BER) performance for the 1x2 router. For a BER of 10e-9 the receiver sensitivity is -26 dB compared with baseline detection without a router of -38 dB. The proposed router displays great potential for use in ultrahigh- speed OTDM networks

Investigation of feeding devices and development of design considerations for a new feeder for micro-sheet forming

Recent review in micro-forming research and technological development suggested that the trend of the development is more focused on the manufacturing processes, machines and tooling, and efforts on the methods and systems for integrated precision material handling are insufficient. Most of the developed micro-forming machines were based on standalone concepts which do not support efficient integration to make them fully automated and integrated. At present, material feeding in micro-forming is not of sufficient precision and reliability for high throughput manufacturing applications. Precise feeding is necessary to ensure that micro-parts can be produced with sufficient accuracy, especially in multi-stage forming, while high-speed feeding is a must to meet the production-rate requirements. Therefore, design of a new high-precision and high-speed feeder for micro-forming is proposed. Several possible approaches are examined with a view to establishing feasible concepts. Based on the investigation, several concepts for thin sheet-metal feeding for micro-forming are generated, they being argued and assessed with applicable loads and forces analysis. These form a basis of designing a new feeder

Comprehensibility of UML-based Formal Model – A Series of Controlled Experiments

This paper summarises two controlled experiments conducted on a model that integrates the use of semi-formal notation, the Unified Modelling Language (UML) and a formal notation, B. The experiments assessed the comprehensibility of the model, namely UML-B. The first experiment compared the comprehensibility of a UML-B model and a B model. In the second experiment, the model was compared with an Event-B model, a new generation of B. The experiments assessed the ability of the model to present information and to promote problem domain understanding. The measurement focused on the efficiency in performing the comprehension tasks. The experiments employed a cross-over design and were conducted on third-year and masters students. The results suggest that the integration of semi-formal and formal notations expedites the subjects’ comprehension tasks with accuracy even with limited hours of training
