Pendekatan konstruktif dalam inovasi pengajaran dan pembelajaran Bahasa Melayu di Kolej Vokasional
Pendekatan konstruktif adalah pendekatan pengajaran dan pembelajaran yang
berpusatkan pelajar manakala inovasi pengajaran pula dikaitkan dengan kaedah
pengajaran yang terbaru demi mengukuhkan pemahaman pelajar. Pembelajaran
berasaskan pendekatan konstruktif merupakan elemen yang penting dan perlu
difahami oleh guru-guru bagi memantapkan proses pengajaran dan pembelajaran
sesuai dengan peredaran masa dan menjayakan proses tranformasi pendidikan
negara. Objektif kajian ini dijalankan untuk mengenal pasti pemahaman guru-guru
bahasa Melayu berkaitan inovasi, mengenal pasti perbezaan yang wujud antara guru
lelaki dan guru perempuan dalam mengamalkan inovasi, pengkaji juga melihat
adakah wujud perbezaan antara guru baru dan guru yang sudah berpengalaman
dalam aspek mengaplikasikan inovasi serta mengenal pasti kekangan-kekangan yang
dialami oleh para guru untuk mengaplikasikan inovasi di sekolah. Seramai 63 orang
guru bahasa Melayu dari lapan buah kolej vokasional telah dipilih sebagai responden
dalam kajian ini. Data dianalisis menggunakan perisian Winsteps 3.69.1.11 dengan
pendekatan Model Pengukuran Rasch. Hasil analisis menunjukkan bahawa guru�guru bahasa Melayu memahami kepentingan inovasi dalam pengajaran dan
pembelajaran. Hasil kajian juga menunjukkan guru-guru perempuan lebih banyak
menerapkan unsur inovasi dalam pengajaran berbanding guru lelaki. Walaupun
begitu, aspek pengalaman tidak menunjukkan perbezaan dari segi pengamalan
inovasi sama ada guru baru ataupun guru yang sudah berpengalaman. Pengkaji juga
mengenal pasti beberapa kekangan yang dialami oleh guru-guru untuk mengamalkan
inovasi ini. Sebagai langkah untuk menangani masalah berkenaan, beberapa
cadangan telah dikemukakan oleh pengkaji bagi memastikan guru-guru dapat
merealisasikan proses pengajaran berkesan dengan penerapan inovasi mengikut
model pendekatan konstruktif. Pengkaji berharap, kajian ini dapat dijadikan sebagai
satu panduan kepada pelaksana kurikulum bagi memastikan budaya inovasi sentiasa
menjadi amalan dalam kalangan guru demi mengangkat profesionalisme guru di

Technology Development in Transition - The Case of Hungarian Industry -
The reform of 1989 exposed Hungarian industry to foreign competition and confronted it to the loss of the vast and undemanding COMECON market, the withdrawal of public support and the need for privatisation. Based on twenty-four interviews in pharmaceutical, electronics, automotive and textile companies, this paper gives insight into the efforts made by Hungarian industry to upgrade its technology in response to these pressures. The patterns found reflect the shift away from the old strategy of autarchic imitation of western technology based on own research and development towards catch-up through acquisition of western product and process know-how. The firms' modernisation activities were heavily driven by foreign investment and financial support from public agencies, but there are drawbacks associated with both, especially foreign investment which has in some cases contributed to the erosion of indigenous research capability. Science and technology institutions played an important role in the upgrading of industrial technology before the reform, but linkages with industry have eroded in the 1990s as a result of the drastic decline in state funding for science and technology and the financial crisis in industry. Financial support from the European Union for science and technology in the sample firms is reviewed and a number of suggestions are made for its improvement, so as to better reflect Hungary's current needs in the context of its increasing integration with the European Union.
The Decidability of Verification under Promising 2.0
In PLDI'20, Lee et al. introduced the \emph{promising } semantics PS 2.0 of
the C++ concurrency that captures most of the common program transformations
while satisfying the DRF guarantee. The reachability problem for finite-state
programs under PS 2.0 with only release-acquire accesses is already known to be
undecidable. Therefore, we address, in this paper, the reachability problem for
programs running under PS 2.0 with relaxed accesses together with promises. We
show that this problem is undecidable even in the case where the input program
has finite state. Given this undecidability result, we consider the fragment of
PS 2.0 with only relaxed accesses allowing bounded number of promises. We show
that under this restriction, the reachability is decidable, albeit very
expensive: it is non-primitive recursive. Given this high complexity with
bounded number of promises and the undecidability result for the RA fragment of
PS 2.0, we consider a bounded version of the reachability problem. To this end,
we bound both the number of promises and the "view-switches", i.e, the number
of times the processes may switch their local views of the global memory. We
provide a code-to-code translation from an input program under PS 2.0, with
relaxed and release-acquire memory accesses along with promises, to a program
under SC. This leads to a reduction of the bounded reachability problem under
PS 2.0 to the bounded context-switching problem under SC. We have implemented a
prototype tool and tested it on a set of benchmarks, demonstrating that many
bugs in programs can be found using a small bound
Non-Traditional Entrants to the Profession of Teaching: Motivations and Experiences of Second-Career Educators
Individuals entering the teaching profession from other fields have much to offer in terms of practical experience in fields such as business, private industry, law enforcement, and the military. The authors examine the phenomenon of second-career teachers with specific emphasis on the motivating factors, common experiences, and reflections concerning the decision to leave already established professions in order to pursue a career in teaching. This particular issue of life vocation has particular interest for the Christian, who wishes to discern and follow the call of God in their personal and professional commitments. The article surveys research into second-career teachers and explores the process of professional preparation of these newfound entrants in the world of education as well as their assimilation to the culture of schools. Themes emerge from the literature for further consideration, which the authors argue, must more intentionally-inform career preparation programs, trends of new teacher recruitment, and teacher shortages in American school districts
Scheduling policies and system software architectures for mixed-criticality computing
Mixed-criticality model of computation is being increasingly
adopted in timing-sensitive systems. The model not only
ensures that the most critical tasks in a system never fails,
but also aims for better systems resource utilization in normal condition. In this report, we describe the widely used
mixed-criticality task model and fixed-priority scheduling
algorithms for the model in uniprocessors. Because of the
necessity by the mixed-criticality task model and scheduling
policies, isolation, both temporal and spatial, among tasks is
one of the main requirements from the system design point
of view. Different virtualization techniques have been used
to design system software architecture with the goal of isolation. We discuss such a few system software architectures
which are being and can be used for mixed-criticality model
of computation
