Integrating new assessment strategies into mathematics classrooms: an exploratory study in Singapore primary and secondary schools
No full textEducational researchers and practitioners have in recent years paid mounting attention to the importance of new assessment (or the so-called alternative assessment) strategies in Mathematics instruction to better reflect the new desired educational goals and shifted values in education. However, research is wanting in this area, particularly in Singapore's educational setting. This project seeks to investigate the influence of using new assessment strategies in Mathematics teaching and learning on students' achievements, in both the cognitive and affective domains, in our local school settings. A quasi-experimental study with about 15-20 teachers at primary and lower secondary levels will be carried out to assess the impact of using a variety of strategies (e.g., projects, journal writing, oral presentation, performance tasks, student self-assessment, classroom observation and interview, etc.) for three school semesters on students' learning. The project will also look into issues concerning how to use new assessment strategies effectively in classrooms in local schools. For this purpose, data will be collected from classroom observation, interviews with teachers and students, and questionnaire surveys. It is hoped that the project will provide research-based evidence and practical suggestions for promoting the effective use of alternative assessment in Singapore Mathematics classrooms. <br/
Stock prediction, trading simulation and options volatility prediction using FASCOM++ (fuzzy associative cortical maps architecture)
No full textFuzzy Associative Cortical Maps Architecture (FASCOM) is inspired from the cortical maps found in many biological and artificial neural systems. The cortical maps organise and represent information obtained from sensory inputs and play important roles in learning and memory processes. FASCOM uses features inspired by the structure and functions of cortical maps and is integrated a linguistic fuzzy model to perform associative learning of input-output pairs. The project undertakes to improve the architecture of FASCOM to incorporate a learning mechanism, so that the network is capable of modifying its properties on the basis of the incoming data leading to better prediction and higher accuracy.
The author aims to validate the modified architecture of FASCOM by conducting benchmarking experiments and observing the improvement in the performance of the system over other systems. For this purpose, various classical datasets for classification and regression problems were used.
The author worked on many real-life application to observe FASCOM++’s performance on real-life data. One of the applications is stock data prediction where the author used Hong Kong stock data and predicted prices using FASCOM++ and compared the results with the actual prices. The analysis of FASCOM++’s performance helps in gauging its practical use in real-life applications such as stock trading. The author simulated a simple stock trading algorithm to compare and evaluate FASCOM++’s performance against other architectures.
The author explored other areas of applications and worked on options volatility prediction which is one of the core areas of research in the financial industry. By exploiting on the online learning capabilities FASCOM++ was able to perform better than the other architectures and demonstrated its capability to be a potential architecture for real-life purpose.Bachelor of Engineering (Computer Science

Recurrent correlation associative memories
No full textThe online technique of neuro-fuzzy system has been increasing in popularity in the recent years. In actuality external factors play an important role in the time-variant dataset, changing its pattern. This change in pattern is known as drift and shift. To tackle these changes, Hebbian learning was introduced. However this learning is characterised by uni-directional learning, resulting in the instability of the model.
Hence, the BCM theory was developed to overcome the problem of Hebbian learning through the provision of Hebbian and Anti-Hebbian learning.
However, time variant data possesses both dynamic and temporal problems. The purpose of the author is to address this issue through the modification of the current recurrent fuzzy neural network. The underlying principle is to store past information to be recalled later for application in the current context.
The existing recurrent neuro-fuzzy system shows promising results that motivates the author to further the efficacy of the recurrent neuro-fuzzy system.
This report proposes a recurrent neuro-fuzzy system that uses the BCM theory of online learning with self-organizing effectiveness. In addition, rules are represented using the Takagi Sugeno Kang model to achieve a better accuracy compared to the Mamdani model which focuses on interpretability.
The performance of Recurrent SeroTSK is evaluated and compared against neuro-fuzzy systems through various time-series benchmark experiments and prediction for cancer diagnosis which is a classification data. The results show that Recurrent SeroTSK is better for time-series prediction and it works for classification data as well.Bachelor of Engineering (Computer Science
Values as resources in career counselling methods: case studies with integrative approach for clients with disabilities in Malaysia
No full textThis article responds to the Government\u27s call for counsellors to extend career guidance, which includes counselling Malaysians for enhancing human capital development with inclusiveness for attaining Vision 2020. This research paper does not study the types and degrees of severity of clients\u27 disabilities or explain the methodology for the integrative approach. It aims at creating awareness among career counsellors in: (1) understanding the integration of values for facilitating clients with disabilities in the counselling processand (2) using this insight for enabling clients to integrate into their society as productive and valued individuals. Hence, three cases of career counselling which were conducted by the author were selected to highlight the uses of values: (1) in Case I to develop objectivity, (2) in Case 2 to build therapeutic goals and (3) in Case 3 to cope with contextual barriers at work and at home. Using case studies, the relevance of the integrative approach is discussed within the context of the clients\u27 own values in the counselling process, facilitating them in integrating into society as productive contributors. However, it is cautioned that career counsellors refrain from imposing their values on clients in using the integrative approach. More dialogue from the counselling fraternity is invited to address the use of the integrative approach in improving inclusiveness at the cross-cultural level
From Cars to Complete Streets: Integrating Bicycles Into Seattle\u27s Transportation Network
No full textThis thesis explores the process of integrating cycling infrastructure into transportation networks in major cities. It starts by contextualizing the process in Copenhagen, Denmark (often called the best bike city in the world) during its cycling movement in the mid-20th Century. The findings from Copenhagen show that cycling is both viewed as a legitimate and respected mode of transportation and that the city layout, density, and topography is conducive to cycling. In the United States, this thesis explores the federal policies that have been created in support of the Complete Streets movement and makes the case that Complete Streets generally yield many benefits. In the final section, this thesis contextualizes these studies with a case study of Seattle and explores the challenges that have been associated with implementing Seattle’s Bicycle Master Plan. Although the city has made some small-scale cycling infrastructure, the number of cyclists in the city remains low and the bike network remains disconnected. There has been tremendous citizen pushback against lanes for fear of increased traffic and gentrification, and Seattle’s layout and topography presents additional challenges. While the author is in support of bicycling and cycle networks, she believes it is important to consider the opposition to implementing this infrastructure so that we can be more deliberate, sensitive, and inclusive with creating cycle networks in the future. The author proposes that cycling infrastructure may need to be done in smaller pockets before a citywide network can be successfully developed
Beginning Architecture: Contextualising Thresholds in Architectural Education
No full textWhere do we begin? Architecture is a profession riddled with many orientations, directions, and perspectives. How one favours what to signify in representation is equally open in processes, methodologies and approaches to form-making, spatial ordering, material choices, and so forth. The educational process is similar; it is riddled with conundrum after conundrum. The education of the architect was not unique; it developed through the artists’ guilds into academies wishing to elevate the discipline, and the mechanical arts, which was a subset of armatura. Carl Goldstein’s Teaching Art traces not only the growth of academies but the shifting issues with craft and thought, noting that both the disciplinary art and their education were always responsive, and often confrontational.1 The Florentine academy, which privileged disegno over Venetian colore, had a responsive curriculum. As soon as the papacy allowed dissections, life drawing and the study of cadavers were not only included, but mandated at the Accademia del disegno. The elevation of the arts with European royal support led to what Goldstein refers to as ‘triumph of the academy’, a consolidation of processes and methods as de rigueur, inadvertently creating strict doctrine and prescribing inflexible methods and values.2 The response to this was, of course, reactionary, and the dialectical confrontation repeats itself many times, over many decades, as a confrontation between mainstream and avant-garde. Other themes that occur and recur in the academies over the centuries are issues of mimesis and exemplars, the antique, art and science, style, originality, craftsmanship, and in the last two centuries, questions of modernisation, modernism, and modernity. The latter aligns with the territories of contestation: modernisation with process, modernism with establishment, and modernity as condition. In our current climate crisis, political shifts, and recent global pandemic; architectural process, establishment, and conditions are again re-examined.Situated Architectur
Design and implementation of control of perching mechanism
No full textUnmanned Aerial Vehicles (UAVs) are aerial vehicles that operate without the need of any human pilot on board. As its popularity to be used in military and civilian domains for various applications are increasing these days, people would prefer a UAV that has a long lasting battery life, thus the need to increase the UAV operation life by different approach.
This report shows the design and implementation of servo motor control for the perching mechanism so as to allow the UAV to perch on objects such as tree branches to conserve power usage. The project prototype was done by two people, one on design and development of the mechanism, and other on developing the sensors and programs to integrate the mechanism and UAV.
As the initial idea for the project was to use two independent controller boards to control the UAV and perching mechanism, the author spent time to build and configure a controller board from scratch by using the PIC18F4520 MCU. The author managed to setup the oscillator, analog digital convertor and PWM generation modules for the perching mechanism use before the idea was then changed to use only the UAV controller board (STM32F4) due to space and weight constrain.
The resulting prototype was able to perform perching on 8cm diameter branch and tube. However, more time is needed to reconfigure the analog digital convertor module of the STM32F4 controller board in-order for the perching mechanism to perform better perching on irregular shape.Bachelor of Engineering (Mechanical Engineering
