Formative and Summative Evaluations in Learning Physics: Do They Complement Each Other?

A correlational study was conducted to analyse the relationship between students’ performance in problem-based learning (PBL) and final exam scores with two student cohorts. This study focused on PBL as a teaching strategy and how it related to the students’ achievement in the final exam of a physics course. Exam reliability was assessed by Cronbach’s alpha, and values were obtained ranging from .71 to .83. Correlation between students’ scores in PBL and the final exam was analysed using Pearson’s correlation coefficient. Statistical significant was shown only for semester 2 in Cohort A. For Cohort A semester 1 and both semesters for Cohort B, the correlations were not significant. The corresponding highest Pearson correlation coefficient was .19, which was only for Cohort A semester 2. Coefficients of determination showed that PBL accounted for about 0 to 3.7% of the variance in students’ final exam scores. In all semesters for both cohorts, the difference between final exam scores and PBL scores was significantly higher in the upper quartile of students’ scores, and lower in the lower quartile of students’ scores. Thus, this study showed that PBL can be implemented as one of the teaching strategies to improve some students’ academic achievement

Classification of Mathematical Transformation Concepts in Pua Kumbu based on Frieze Patterns

Pua Kumbu, the beautiful traditional textile of the Iban in Sarawak, is generally appreciated for its exquisite patterns and designs. This paper aims to explore the examples of mathematical ideas which exist in motifs produced by weavers in Sarawak. Although it is still in the form of preliminary observations, it has been revealed that the principles of geometry such as enlargement, reflection, rotation, and translation are often used in the Pua Kumbu patterns in Sarawak. This woven art by the Ibans indirectly applies the principles of geometry in the form of beautiful and high-value motifs, even if they are not familiar with the concept of transformation taught in school. The observation and interview sessions were conducted with the weavers to identify some of the basic mathematical concepts such as transformations, accuracy and equality, measurement and estimation

Analysis of Frieze Patterns Concepts in Pua Kumbu

A traditional practice of the Iban from Sarawak, Pua Kumbu is a form of textile which is famous for its beauty. There is a general appreciation of how it is exquisitely designed and patterned. It has been recognised by analytical studies that Pua Kumbu designs use transformational geometrical shapes in the frieze. This paper explores the geometry elements that have been portrayed in the form of different flora and fauna motifs. The examples of mathematical ideas in motifs produced by weavers in Sarawak have been analysed through this study. Although it is still in the form of preliminary observations, it has been revealed that the principles of geometry, such as enlargement, reflection, rotation, and translation are often used in the Pua Kumbu patterns. This woven art by the Ibans indirectly applies the principles of geometry in the form of beautiful and high-value motifs. This paper may benefit this field and the professionals related to it to act as a useful guideand also may serve as a point of reference for future studies on the unique patterns and designs of Pua Kumbu. The study also suggests that patterns based on geometry and symmetry exist in the ways Pua Kumbu is created

Correlation of Different Peat Soil Index Properties

The present study focuses on the physical properties of Sarawak peat soil and identifies the correlation between the index properties of peat from the present study and various locations in Malaysia. The physical properties of peat from the present study were obtained on site and in the laboratory, including degree of humification, moisture content, organic content, fibre content, specific gravity, liquid limit, linear shrinkage, and pH. The data obtained in this study and other tropical peats in Malaysia were compiled to identify their correlations. The correlation results reveal that with an increase in organic content, there is also an increase in value of moisture content, while the value of specific gravity reduces. Furthermore, as the bulk density of peat increases, the value of organic content reduces. Also, the moisture content, organic content, and fibre content of peat decrease with the increasing value of degree of humification. The correlations between different peat soil index properties have R2 values ranging from 0.75 to 0.85, showing that the peat soil index properties are consistent with findings from previous studies, in which comparable trends are found. Thus, these correlations are expected to be useful for researchers and engineers to understand the peat soil's preliminary behaviour

Development Of Conversational Agent To Enhance Learning Experience: Case Study In Pre University

Chatbot is an artificial intelligent application that can converse with a user through textual or auditory method. The chatbot can give a response according to their characteristic and domain knowledge. This study aims to evaluate the use of chatbot named eLVA among students at the Centre for Pre University Studies. A series of 10 questions was distributed to 40 students to evaluate the use of eLVA after they have experienced it. The results indicated that chatbot are most likely to be very helpful in teaching and learning because it has helped students getting an instant response. However, results showed that the main reason for students to stop using chatbot involved getting incorrect information and worried about Chatbot making mistakes. The result further show that there is no significant difference in the use of eLVa between male and female students. The study also found that there is no significant correlation between study program (Physical Sciences/Life Sciences) towards the use of eLVA

Critical Thinking Session (CTS)

CTS in Physics course provides quantitative and analytic skills needed for analysing data and solving problems in the sciences area. It involves crafting a learning environment where students can explore on their own and understand how the physical world works, and to connect complex scientific concepts to their daily lives. This activity requires students to work as a team

Scienceploration 2023

The Scienceploration Camp is an initiative of the Centre for Pre-University Studies, UNIMAS (PPPU), which aims to increase the interest in science among secondary school students. It is also an effort taken by PPPU towards the achievement of Sustainable Development Goals 4 in providing equal quality education and promoting lifelong learning opportunities for all. On top of that, this camp supports Sarawak’s Digital Economy Strategy in nurturing an integrated ecosystem to foster inclusive digital society, by building the right foundations to grow our local digital economy

Analysis Of Crystallographic Patterns Of Iban Pua Kumbu

One of the famous traditional textiles in Sarawak is the Iban Pua Kumbu. This paper presents the crystallographic patterns, geometry concept and symmetry analysis present in the Iban Pua Kumbu patterns. This paper will also look at the colour-symmetrical patterns and motifs used in these textiles. The Ibans' weaving technique subtly incorporates geometric concepts using exquisite and precious designs. The Pua Kumbu of the Iban can be similarly classified according to the patterns displayed in the wallpaper and frieze. The current research findings could assist students to learn mathematics. In this study, samples comprising eight (8) repeated patterns were collected from field visits, museums in the Sarawak, and personal collections of scholars. From the findings, it shows that all Pua Kumbu patterns bear at least one of the seventeen crystallographic groups. Most of the Pua Kumbu motifs are symmetrical and those motifs is mathematically identified as a design. The Pua Kumbu contains decorative patterns whose relevance and imaginative portrayal are demonstrated by the intricacy of the creative process. Pua Kumbu weavers appear to have excellent memory skills, strong visual perception, and an innate aptitude for applying mathematics to their work
