AbstractTeaching and learning of quantum physics at secondary level is an active field of research. One important challenge is finding ways to promote understanding of quantum concepts without the mathematical formalism that is embedded in quantum mechanics but unavailable on the secondary level. We investigated Norwegian secondary students’ (N = 291) descriptions of the wave nature of quantum particles and the uncertainty principle, as expressed during work with learning resources using a sociocultural approach emphasizing history, philosophy, and nature of science aspects. Responses from university students (N = 40) given after a formalism-based course in quantum physics were included for comparison. Themes were identified using thematic analysis and analyzed from the perspective of pedagogical link-making, seeing different themes as representing different levels of explanations of the concepts (phenomenological, qualitative, mathematical). The most dominant theme in descriptions of particle wave nature was that particles exhibit wave behavior in experiments, while referring to the mathematical description of particles by wave functions was a less prominent theme, even among university students. Two uncertainty principle themes were found: uncertainty as inability to measure pairs of variables precisely, and uncertainty as innate blurriness in nature. Largely missing from descriptions of both concepts were meaningful links between different levels of explanations. Based on the results, we discuss ways forward for teaching particle wave nature and uncertainty in secondary education.

New View

The romanticism of management for numbers, metrics and deterministic models driven by mathematics, is not new. It still exists. This is exactly the problem which classical physicists had in the late 19th century until Werner Heisenberg brought the uncertainty principle and opened the doors of quantum physics that challenged the deterministic view of the physical world mostly driven by the Newtonian view. In this paper, we propose an uncertainty principle of management and then list a set of factors which capture this uncertainty quite well and arrive at a new view of scientific management thought. The new view which we call as the Quantum view of Management (QVM) will be based on the major tenets from the ancient philosophical traditions viz., Jainism, Taoism, Advaita Vedanta, Buddhism, Greek philosophers (like Hereclitus) etc.

Output Hypothesis

Abstract South African Sign Language (SASL) has become an increasingly popular language that hearing university students want to learn as a second language. This requires more qualified SASL instructors and new curricula at South African universities. This paper considers ways in which challenges associated with the teaching and learning of SASL can be overcome. Krashen’s Comprehension Input Hypothesis and Swain’s Output Hypothesis form the theoretical framework as reference to our own independent experience, praxis, and reflection. This study considered different teaching methods and pedagogies and found the post-method approach suggested by Kumaravadivelu (2003) a viable method for teaching SASL as a second language. This method aligns with the method we had independently identified as the most empowering for teachers to create their own strategies focused on their intuition, experiences and pedagogy. Therefore, we do not favour one specific method above another, but rather adopt an integrated approach. We make a few suggestions regarding sign language curriculum content and further research in sign language as an L2, which need urgent attention.

Real Picture

With the progress of time, the aim of teaching and learning English as a Second Language (ESL) or English as a Foreign Language (EFL) changed, and so did the approaches and methods in language teaching. Different methods and approaches emerged and were replaced, influenced or contributed to the emergence of new methods. It is widely acknowledged that one umbrella approach to language teaching that has become the accepted "norm" in this field is the Communicative Language Teaching Approach. This study deals with the theories and practices of CLT at the Higher Secondary level in Bangladesh. Realizing the significance of CLT, The Ministry of Education in Bangladesh made groundbreaking attempts to implement CLT in the new context and also brought some changes in the curriculum in 1990s. Along with attempting to provide a real picture of how CLT is practiced and utilized in an ESL/EFL context, this study focuses on the Practice of CLT approach in Bangladesh. Moreover, this study intends to propose some propositions to be implemented for better practice of CLT in ESL/EFL contexts.IIUC Studies Vol.12 December 2015: 71-86

Artikel ini menyajikan apa itu pembelajaran kontekstual dan apa saja karakteristiknya? Apa itu kemampuan penalaran statistis? Mengapa pembelajaran kontekstual dapat mengembangkan kemapuan penalaran statistis siswa Sekolah Menengah Pertama? Kemampuan penalaran statistis sangat penting dimiliki oleh siswa Sekolah Menengah Pertama, karena dengan kemampuan penalaranr statistis ini siswa dapat memiliki kompetensi dalam hal: 1) memahami informasi-informasi statistis yang tersurat maupun yang tersirat pada setiap permasalahan yang dihadapi. 2) Pemahaman yang baik terhadap bagaimana cara memilih, menyajikan, mererduksi, dan mempresentasikan data yang akan digunakan untuk menjawab permasalahan yang ada. 3) pemahaman dan penalaran yang baik terhadap proses statistis secara keseluruhan termasuk setiap perhitungan yang terlibat dalam proses tersebut. 4) pemahaman untuk memecahkan masalah secara statistis berdasarkan data yang ada, dan menginterprestasikannya dalam pengambilan keputusan yang dapat berlaku secara umum. Oleh karena itu untuk mengembangkan kemampuan penalaran statistis tersebut harus mempertimbangkan pendekatan pembelajaran yang digunakan untuk siswa Sekolah Menengah Pertama. Model pendekatan pembelajaran yang sesuai untuk siswa Sekolah Pertama salah satunya adalah pendekatan pembelajaran kontekstual (Contextual Teaching and Learning). Pendekatan pembelajaran kontekstual ini mengambil permasalahan-permasalahan dalam kehidupan sehari-hari atau permasalahan yang disimulasikan dengan dialog, diskusi,, tanya jawab, dan representasi. Aktivitas pengajaran kontekstual yang dikembangkan adalah: a) belajar berbasis masalah, b) belajar dengan multi konteks, c) belajar mandiri, d) penilaian otentik, dan e) masyarakat belajar.This article presents a contextual learning what it is and what are its characteristics? What is the statistical reasoning skills? Why contextual learning can develop statistical reasoning Traffic junior secondary students? Reasoning ability is very important statistical owned by junior high school students, because of the ability of these statistical penalaranr students may have competence in terms of: 1) understand the statistical information expressed or implied in any problems faced. 2) A good understanding of how to choose, present, mererduksi, and present data that will be used to address existing problems. 3) understanding and reasoning that both the statistical process as a whole including any calculations involved in the process. 4) understanding to solve the problem of statistically based on existing data, and interpret it in decision-making that can be applied generally. Therefore, to develop the statistical reasoning skills should consider learning approach used for junior secondary students. Model learning approach that is appropriate for school students first one of which is a contextual learning approach (Contextual Teaching and Learning). This contextual learning approach to take problems in daily life or simulated problems with dialogue, discussion ,, question and answer, and representation.
