Helping as participation in an open online community: an exploratory study

Abstract

The study explores the issues of participation, and to an extent, learning in an open online community of independent game developers, GameSalad.com. GameSalad is a firm-hosted online support forum for a desktop application of the same name. It is geared to provide members and users with a platform for sharing of information pertaining to their game development, and a place to seek and provide help. It is a large community with over 114,000 registered members (as of March 2015), with an average of 106,000 monthly active unique users, and a high degree of activity such as the posting of tutorials and tips, sharing game development progress, and announcing the launch of a new game. However, the majority of the interactions on the forum are concerned with seeking and providing help. This study focuses on issues around community, participation, and learning within online networks and is underpinned by a concern for participatory and social experiential perspectives on learning.

Mohd Hafiz Mohamad Tarmizi

Abstract

Kajian ini bertujuan untuk mengenal pasti tahap kefahaman membaca murid pasca LINUS dan murid arus perdana di sekolah rendah. Metodologi kajian menggunakan kaedah campuran yang melibatkan kaedah kualitatif berdasarkan analisis transkrip responden serta kaedah kuantitatif berdasarkan kekerapan dan peratus keputusan ujian saringan responden. Dapatan kuantitatif menunjukkan kebanyakan tahap kefahaman membaca murid pasca LINUS adalah pada tahap yang rendah dan hanya segelintir murid berada pada tahap kefahaman literal. Tahap kefahaman membaca murid arus perdana pula berada pada tahap sederhana dengan sebahagian mereka menguasai tahap kefahaman literal dan segelintir menguasai tahap kefahaman taakulan. Dapatan kualitatif pula menunjukkan kualiti kefahaman murid pasca LINUS berada pada tahap yang paling rendah kerana mereka tidak memahami petikan yang dibaca, tidak mampu mengingat semula watak dan plot dalam petikan. Murid arus perdana pula hanya mencapai tahap kefahaman asas; tahap literal .....

Hernagine type of Aporphine Alkaloids from Alseodaphne perakensis

Md Nazimuddin Mahfuzah, Husna Hasnan Muhammad Hafiz, Ahmad Kartini, Awang Khalijah, Nafiah Mohd Azlan,

Abstract

A phytochemical study of the stem bark of Alseodaphne perakensis (Lauraceae) had been carried out. The dichloromethane crude extract from stem bark of Alseodaphne perakensis (Lauraceae) yielded two hernagine type of aporphine alkaloids namely oxohernagine and N-methylhernagine. The isolation and purification of these alkaloids were achieved using Column Chromatography (CC) and Preparative Thin Layer Chromatography (PTLC) techniques. The structural elucidations were performed by spectral methods notably Nuclear Magnetic Resonance (NMR) Spectroscopy one-dimentional (1H, 13C and DEPT) and two-dimentional (COSY, HMQC/HSQC and HMBC)...

Influence of different body position and bicycle setup on muscles activity and joint kinematics during cycling

Abdul Hafiz Ahmad Sazili

Abstract

The current study investigated how saddle setup and body positions may influence muscle activity and joint kinematics. All 16 recreationally active participants have been tested in an upright and drop body positions. In each body positions tested, participants went through four different saddle setup for determination of which saddle setup influence the most of the muscle activity and cycling kinematics. The results showed that the changes during cycling from an upright position to drop position significantly influenced two out of eight muscles tested. The results also showed that five out of eight muscles tested were significantly different when compared to saddle setup position. As a conclusion, saddle setup is the most important factor that influence muscle activity. Results indicated that 10-degree saddle inclination setup influence more muscle activity than other saddle setup. This result was important to those who participated actively in this cycling sport to understand the beha.....

Data yang dikumpul dianalisis dengan menggunakan statistik deskriptif dan analisis regrasi. Dapatan kajian ini menunjukkan literasi geografi aras rendah dalam kalangan mahasiswa pendidikan geografi di UPSI adalah berada di tahap yang sederhana (51.74%). Dapatan daripada analisis regrasi pula menunjukkan bahawa pembolehubah X7 iaitu kekerapan membaca buku mempunyai hubungan yang positif dan signifikan dengan tahap literasi geografi dalam kalangan responden. Buktinya, bagi setiap 0.137 kali peningkatan kekerapan membaca buku dalam setahun menentukan tahap literasi geografi dalam kalangan responden. Dapatan daripada kajian ini penting dalam menunjukkan tahap literasi geografi dalam kalangan bakal guru yang akan ditempatk.....

Exploring the effect of an integrated STEM-based water rocket module on STEM elements application in a selected science school: a case study

Nur Rosliana Mohd Hafiz

Abstract

The aim of the study is to develop an integrated STEM-based water rocket module, known as SEMARAK (SElangkah Menuju Angkasa RAya Kita) and explore its effect on STEM elements application in a selected science school. The study was divided into two stages, namely the module development stage and the module effect study. Sidek Module Development Model (SMDM) was used in the first stage. The module development stage involved validity evaluation by seven STEM subjects' experts. A pilot test was conducted for reliability evaluation on a group of Form Three pupils (the first batch undergoing the Kurikulum Standard Sekolah Menengah (KSSM)). In the second stage, a single-case embedded case study was conducted to explore SEMARAK's effect on STEM elements application. Representatives from eight subgroups among 32 Form Four participants from a science school in Kuala Lumpur were selected as respondents.

Mohd Hafiz Md Hanif

Abstract

Numerous students suffer from academic procrastination; it is a common problem and phenomenon in academic settings. Many previous researchers have analyzed its relationships with other factors, such as self-regulation and academic success. This paper aims to provide a full outline of academic procrastination and explore the current hot spots and trends. Bibliometrix and VOSviewer were used to conduct quantitative analysis. The data was collected from the Web of Science core collection database, which contains 1,240 articles from the years 1938 to 2021. The analysis shows that the publication of articles on academic procrastination has been rapidly increasing since 1993. In terms of the most influential countries and institutions, the United states took a prominent lead among all countries, and the most productive institutions in this area were the University of Washington and University of California, Los Angeles. By analyzing the authors, we see that most authors like working with a f.....
