Enhancing automatic control learning through Arduino-based projects

Systems dynamics and automatic control is classified as one of the toughest courses in the college of engineering at Qassim University according to the statistical analysis of the final grades. This motivated us to think about a new approach to teach this course by extending the design term project to include experimental part beside the theoretical analysis. This approach has become feasible due to the publicity of the low-cost microcontrollers such as the Arduino in the recent years. In this paper, we present our experience in conducting Arduino-based projects and how we used them to support the teaching of all the automatic control subjects in the course such as the mathematical modelling, the stability analysis, the controller design and the implementation of the PID controller. It was found that the new approach improves the attention and the overall performance of the students in the course which was reflected in the students’ marks in the quizzes and exams. Moreover, it motivated the students to be creative by utilising the control theory to design new systems that can be useful for their local community.     

喀什地区基础教育新课改现状及其对我院的启示

探讨南疆基础教育教师对新课程改革方案的适应性问题,对于新课程改革的顺利实施有着重要意义。调查研究表明,喀什地区敦师对新课程改革的理念持认同态度并表现出一定的适应性;但也存在一些问题,如教师的观念与现实脱节、教师的心理不适应新课改等。为此我们依照喀什师范学院学习实践科学发展观活动预先设计好的思路进行了较为深入、全面的调查,并获得了对于我院人才培养质量提高和人才培养模式改进的有益启示和建设性意见。

Islamic parents’ attitudes and beliefs towards school-based sexual and reproductive health education programmes in Oman

School-based comprehensive sexuality education (CSE) programmes play an important role in reducing young people’s sexual risk behaviour and promoting health and well-being. There is limited evidence regarding the attitudes and beliefs of parents towards the implementation of school-based CSE programmes in Islamic cultural settings, including Oman, which this mixed-method study set out to explore. A convenience sample of 250 parents, with equal numbers of mothers and fathers of children aged 12–14 years (grades 7–9) at two urban public pre-secondary schools in Saham, completed a paper-based self-administered questionnaire in Arabic. We found most parents (72.8%) supported school-based CSE programmes that conformed to Islamic requirements of pre-marital sexual abstinence, but there was some opposition. Almost all parents supported comprehensive age-appropriate CSE being taught to students aged 10–15 years, including topics perceived as controversial in Omani culture, except for birth control and safer sex. Most parents considered themselves, school teachers and school nurses to be important sources of CSE. The study findings which suggest strong parental support for CSE programmes can facilitate education policy, CSE curriculum decision-makers and school healthcare-providers in Oman, other Middle Eastern countries, and countries with Muslim immigrant populations.     

Research assessment by percentile-based double rank analysis

In the double rank analysis of research publications, the local rank position of a country or institution publication is expressed as a function of the world rank position. Excluding some highly or lowly cited publications, the double rank plot fits well with a power law, which can be explained because citations for local and world publications follow lognormal distributions. We report here that the distribution of the number of country or institution publications in world percentiles is a double rank distribution that can be fitted to a power law. Only the data points in high percentiles deviate from it when the local and world μ parameters of the lognormal distributions are very different. The likelihood of publishing very highly cited papers can be calculated from the power law that can be fitted either to the upper tail of the citation distribution or to the percentile-based double rank distribution. The great advantage of the latter method is that it has universal application, because it is based on all publications and not just on highly cited publications. Furthermore, this method extends the application of the well-established percentile approach to very low percentiles where breakthroughs are reported but paper counts cannot be performed.     

Statistical Process Control Charts for Measuring and Monitoring Temporal Consistency of Ratings

Methods of statistical process control were briefly investigated in the field of educational measurement as early as 1999. However, only the use of a cumulative sum chart was explored. In this article other methods of statistical quality control are introduced and explored. In particular, methods in the form of Shewhart mean and standard deviation charts are introduced as techniques for ensuring quality in a measurement process for rating performance items in operational assessments. Several strengths and weaknesses of the procedures are explored with illustrative real and simulated rating data. Further research directions are also suggested .     

Effect of Ball Mass on Dribble,Pass, and Pass Reception in 9–11-Year-Old Boys' Basketball

The objective of the study was to analyze the effect of ball mass on dribble, pass, and pass reception in real game situations in 9–11-year-old boys' basketball. Participants were 54 boys identified from six federated teams. The independent variable was ball mass, and dependent variables were number of dribbles, passes, and pass receptions. Three situations were established in which the participants played four games with each of the following: (a) regulation ball (485 g, 69–71 cm), (b) ball of smaller mass (440 g, 69–71 cm), and (c) ball of greater mass (540 g, 69–71 cm). Four observers recorded data from observing game videos using a computerized register instrument. Participants executed more dribbles, passes, and pass receptions with the 440-g ball when compared to the regulation (p < .05) and 540-g ball (p < .01). Reduction of ball mass seems to have enabled the children to go from paying attention to aspects related to ball handling to aspects of game interpretation.     

An easy-to-hard effect after nonreinforced preexposure in a sweetness discrimination

Experiments 1A and 1B used a taste-aversion procedure with rats to demonstrate that exposure to easily discriminated flavors along a dimension (1 % and 10 % sucrose) can facilitate learning a subsequent hard discrimination (4 % and 7 % sucrose) when one of those flavors is paired with illness. Experiment 1A compared the effects of preexposure to the easily discriminated flavors against exposure to the same stimuli used in the discrimination training or no exposure at all. Experiment 1B replicated the conditions in Experiment 1A, with 2 additional days of training and unrestricted access to the flavors on CS+/CS– trials in discrimination training. Contrary to findings with multidimensional stimuli (Scahill & Mackintosh, Journal of Experimental Psychology: Animal Behavior Processes, 30, 96–103, 2004; Suret & McLaren, The Quarterly Journal of Experimental Psychology, 56B, 30–42, 2003), we found that preexposure to the easily discriminable stimuli varying along a single dimension of sweetness facilitated subsequent discrimination training over the other conditions in each experiment. We discuss the results in terms of the ideas presented by Gibson (1969) and Mackintosh (Psychological Review, 82, 276–298, 1975) and in terms of hedonic variables not considered by theories of perceptual learning.
