Both biology and mathematics have existed as well established branches of science for hundreds of years and both, maybe not in a well defined way, have been with the humankind for a couple of thousands of years.  Though nature  was studied by the ancient civilizations of Mesopotamia, Egypt, the Indian subcontinent and China, the origins of modern biology are typically traced back to the ancient Greece, where Aristotle (384-322 BC) contributed most extensively to its development. Similarly,  the  ancient Babylonians were able to solve quadratic equation over four millennia ago and we can see the development of mathematical methods in all ancient civilisations, notably in China and on the Indian subcontinent. However, possibly again the Greeks were the first who studied mathematics for its own sake, as a collection of abstract objects and relations between them.  Nevertheless, despite the fact that the development  of such a mathematics has not required any external stimuli, an amazing feature of the human mind is that a large number of abstract mathematical constructs has proved to be very well suited for describing natural phenomena.This prompted Eugene Wigner to write his famous article The Unreasonable Effectiveness of Mathematics in the Natural Sciences,  ...

This paper describes utilization of GPS data in Korea Peninsula and IEODO ocean research station for investigation of postseismic deformation characteristic after the 2011 Tohoku-oki Mw9.0 Earthquake. Analytical logarithmic and exponential functions were used to evaluate the postseismic deformation parameters. The results found that the data in Korea Peninsula and IEODO during periods of mid-2011 – mid-2014 are fit better using logarithmic function with deformation decay at 134.5 ±0.1 days than using the exponential function. The result also clearly indicates that further investigation into postseismic deformation over longer data span should be taken into account to explain tectonic deformation over the region.

The low level of pupils’ knowledge and skills in science and mathematics is a serious problem in the economic development of the country. Cognitive interest is a crucial learning motive; no successful learning process is possible without inciting interest. Grade 9 pupils were surveyed to find out the respondents’ cognitive interest in the field of exact sciences. On average the interest in subjects of exact sciences is poorly pronounced. Respondents have good understanding about the causal relations while the cognitive activity, the skill to overcome difficulties in learning is low. Cognitive interest in learning is promoted by diverse methodological approaches that are oriented towards pupils’ self-actualization and purposefulness. Key words: cognitive interest, learning process, science and mathematics.

The Impact

Dasar pengajaran dan pembelajaran Sains dan Matematik dalam bahasa Inggeris (PPSMI) telah dilaksanakan dalam sistem pendidikan di Malaysia sejak tahun 2003. Perlaksanaan polisi ini telah melalui satu kitaran. Pelajar sekolah yang mula belajar dalam tingkatan satu serta pelajar matrikulasi di pelbagai pusat pengajian tinggi di Malaysia telah menjejakkan kaki ke pusat pengajian tinggi khususnya di Universiti Teknologi Malaysia (UTM), Skudai, Johor. Kertas kerja ini akan memberi sedikit gambaran tentang kesan perlaksanaan polisi ini terhadap pelajar di beberapa buah fakulti yang diambil secara rawak di UTM. Kajian ini meneliti kesan polisi PPSMI terhadap tiga aspek, iaitu kesediaan, minat dan keyakinan dalam kalangan pelajar UTM. Seramai 309 orang pelajar tahun tiga daripada Fakulti Pendidikan, Fakulti Sains dan Fakulti Kejuruteraan Mekanikal di UTM telah dijadikan sampel dalam kajian ini. Alat kajian yang digunakan untuk mengukur tahap kesediaan, minat dan keyakinan pelajar adalah set soal selidik yang mengandungi 34 item berskala Likert yang mempunyai lima pilihan respon beserta dua soalan terbuka. Nilai kebolehpercayaan alat kajian adalah α = 0.895. Analisis statistik deskriptif dan inferensi telah digunakan dalam tatacara menganalisis data. Secara keseluruhannya, tahap kesediaan, minat dan keyakinan pelajar adalah pada tahap sederhana dan kurang memuaskan. Walau bagaimanapun, majoriti pelajar bersetuju dengan pelaksanaan polisi terbabit dan menyatakan bahawa PPSMI penting bagi peningkatan penguasaan Bahasa Inggeris untuk kejayaan dalam kerjaya dan masa depan mereka. Kata kunci: Pengajaran dan pembelajaran sains dan matematik dalam bahasa Inggeris (PPSMI); kesediaan; minat; keyakinan; pusat pengajian tinggi The controversial policy of teaching Science and Mathematics in English (ETeMS) was implemented in the Malaysian school system since 2003. This policy had passed through a complete cycle where form one secondary students and Malaysian Matriculation College who were affected by this policy have entered higher institution of education specifically in Universiti Teknologi Malaysia (UTM), Skudai, Johor. This paper will give an insight of the impact of the policy on the students affected based on sample of students taken at random in several faculties in UTM. This study focused on the impact of ETeMS on three aspects: student’s readiness, enthusiasm and confidence. A total of 309 third year students from Faculty of Education, Faculty of Science and Faculty of Mechanical Engineering were taken as samples. An instrument to measure the level of student’s readiness, enthusiasm and confidence was a questionnaire containing 34 items with five choices of response using Likert scale along with two open–ended questions. Reliability value of the instrument was α = 0.895. Descriptive and inferential statistics were used in the data analysis. As a whole, the result showed that the level of student’s readiness, enthusiasm and confidence were average and less satisfactory in scores. However, the majority of the students agreed with the implementation of the policy and stated that ETeMS is instrumental in improving their command of English and is neccessary for their future undertakings. Key words: Teaching science and mathematics in English (ETeMS); readiness; enthusiasm; confidence; higher institution of education

Generalized Probability

From the integration of nonsymmetrical hyperboles, a one-parameter generalization of the logarithmic function is obtained. Inverting this function, one obtains the generalized exponential function. Motivated by the mathematical curiosity, we show that these generalized functions are suitable to generalize some probability density functions (pdfs). A very reliable rank distribution can be conveniently described by the generalized exponential function. Finally, we turn the attention to the generalization of one- and two-tail stretched exponential functions. We obtain, as particular cases, the generalized error function, the Zipf-Mandelbrot pdf, the generalized Gaussian and Laplace pdf. Their cumulative functions and moments were also obtained analytically.

Cognitive interest is a vital learning motive for the successful learning process. Nowadays students’ interest about science and mathematics are decreasing. The aim of the study is to explore the cognitive interest of Grade 9 students in science and mathematics. Students were surveyed and it helped to explore the respondents’ cognitive activity and the cognitive interest regarding the understanding of causal relations, research activity and the solution of practical problems. The level of cognitive interests on the three level scales is average for the whole sample of respondents. The survey shows that students do not possess explicit cognitive activity; learning happens rather passively, without initiative; however, they have rather pronounced interest to explore and solve problems connected with the real life. Some implications for teachers on how to increase learners’ cognitive interest are provided in the conclusion. Key words: cognitive interest, learning process, science and mathematics.

This study investigates the ultraslow diffusion by a spatial structural derivative, in which the exponential function ex is selected as the structural function to construct the local structural derivative diffusion equation model. The analytical solution of the diffusion equation is a form of Biexponential distribution. Its corresponding mean squared displacement is numerically calculated, and increases more slowly than the logarithmic function of time. The local structural derivative diffusion equation with the structural function ex in space is an alternative physical and mathematical modeling model to characterize a kind of ultraslow diffusion.
