This study explores how laboratory activity with the argumentative approach could promote
students' conceptual understanding in the Hess' law energy cycle through laboratory work.
Laboratory work with an argument-based inquiry instructional strategy was set up to 15 preuniversity
students from one of the Form 6 Centre at the West Coast Division of Sabah,
Malaysia. The laboratory work consists of a guided inquiry-based instruction with an
argumentative approach in the topic of thermochemistry. The students' understanding of the
energy processes was analyzed with a qualitative method using a semi-structured interview
and triangulated with conversation analysis. The data collected from students' conversation
during the activity was then triangulated with reflective writing at the end of the laboratory
lesson. The study shows the students' prior knowledge and argumentation discourse
significantly influences the development of conceptual understanding. This study emphasizes
argument-based inquiry (ABIIS) in laboratory work to enhance their conceptual knowledge in
the laboratory.
Black pod rot is the most economically important disease of cocoa in Malaysia which is
mainly caused by a highly polyphagous Phytophthora species, called Phytophthora palmivora.
The fungus could attack all parts of the cocoa plant organs and caused various diseases at
any growth stage from seedling until the mature stages, especially during raining season. The
application of synthetic fungicides has been widely recommended to manage the disease but
their repeated use had led to other problems such as environmental, human health and
development of fungicide resistance issues. This study isolated and identified Phytopththora
isolate from a cocoa pod sample based on micro-morphological characters. Besides, the
present investigation was undertaken to screen for the antifungal potency of different weed
extracts against the Phytophthora pathogen using poisoned food technique. The fungal isolate
was successfully recovered from pod tissues of clone PBC123 on 20% tomato juice agar
culture (20T). Only one out of ten weed extracts tested showed a significant in vitro inhibitory
effect towards mycelial growth of Phytophthora isolate, which was aqueous crude leaf extract
of Solanum torvum (42.68%). This study indicated that the potential of weed extracts in the
management of Phytophthora diseases, and may offer more natural, effective and economical
control methods.
Plants have sustained the life of man since the beginning of the time. Their functionalities go beyond being wood for fire, instead, they are able to protect, provide and nourish. The many purposes of plants have been described by many. In this article, we will describe functional plants through the chemical perspective particularly the biologically active secondary metabolites. The initiatives in natural products studies can be traced to the early years of man when plants were used for health and treatment management as documented in traditional materia medica. In modern days, numerous phytochemicals have become the main ingredients in drugs, foods, cosmetics and many more after detailed and rigorous research programs which determine their safety and efficacy. In Malaysia, and Sabah in particular, efforts are planned and carried out to identify potential traditional plants that will be beneficial in their truest forms.
Words have a habit of appearing in recurrent patterns. These recurring patterns may take the
form of phrasal verbs, collocations, and other multi-word expressions (MWEs). Since these
patterns constantly re-occur in both speech and writing, it would seem prudent to teach
vocabulary to ESL learners in the manner in which words actually present themselves: in
typical chunks. A common example of such a chunk would be “to deal with the problem”, in
which “deal with” and “problem” are collocates. This paper contains three sections. The first
examines what phrasal verbs and collocates are in the first place, and why they are particularly
important for learners. The second part is a review of recent studies that support the teaching
of MWEs and chunking pedagogy. This paper concludes by discussing the potential of
incorporating chunking pedagogy in one’s own ESL vocabulary teaching.
Electromyography (EMG) is a random biological signal that depends on the electrode
placement and the physiology of the individual. Currently, EMG control is practically limited
by this individualistic nature and requires per session training. This study investigates the
EMG signals based on six locations on the lower forearm during contraction. Gesture
classification was performed en-bloc across 20 subjects without retraining with the objective
of determining the most classifiable gestures based on the similarity of their resultant EMG
signals. Principle component analysis (PCA) and linear discriminant analysis (LDA) were the
principal tools for analysis. The results showed that many gesture pairs could be accurately
classified per channel with accuracies of over 85%. However, classification rates dropped to
unreliable levels when up to nine gestures were classified over the single channels. The
classification results show universal classification based on a common EMG database is
possible without retraining for limited gestures.
Generally, pineapple sucker is used as the main planting material for commercial cultivation
of pineapple. Pineapple sucker is usually obtained either from the stalk or the stem of a
pineapple plant. Research to study the effect of planting media using mineral soil as the main
component for the mixture on the growth of sucker by stem cutting technique was conducted. The objective of this research is to study the effects of mineral soil-based mixed planting
media on the growth of pineapple suckers produced cultivated via stem cutting of Madu
pineapple. The research was conducted at the Pineapple Nursery of the Faculty of Sustainable
Agriculture, UMS Sandakan, from March 2019 until September 2019. The treatments used in
this research were, soil as T1 (100%); Soil:coco peat as T2 (1:1,v/v); Soil:peat soil as T3
(1:1,v/v); Soil:sand as T4 (1:1,v/v). The data obtained showed there is a significant difference
in the number of a successfully germinated sucker. However, no significant difference was
detected for the sucker growth parameters. Planting media T3, soil: coco peat recorded the
highest number of successfully germinated suckers (12.25). Meanwhile, for growing media, suggested T2 soil: peat soil were recorded the highest for root length (15.53 cm), leaf number
(18.00), and stem diameter (2.18 cm) at 60 days after transplant (DAT).
Heterotrigona itama is a Malaysian stingless bee species that actively reared for meliponiculture. This stingless bee is cultivated in a commercial scale for its honey production, propolis and among the greatest commercial potential as crop pollinators. However, this species has been potentially exposed to agronomic practices, among which the use of synthetic insecticides against pests.The indirect toxicity effect of the post-insecticide had affected the mortalities of H. itama especially, to the foragers. Due to that, a study has been conducted to determine the lethal concentration of 50% (LC50) and 95% (LC95) of the selected insecticides against stingless bee forager workers through residual exposure. The bioassay test was conducted to the local stingless bee H. itama at Agricultural Research Station, Tenom. Four commonly used insecticides in crop protection; Deltamethrin, Chlorpyrifos, Cypermethrin and Malathion were tested at five concentrations that diluted with 500 ml of distilled water in three replications for each insecticide. Lethal concentrations (LC50 and LC95) were obtained from probit analysis after 1-hour dry residues exposure and 24-hour mortality observation. The result shows that; all four tested insecticides were harmful to H. itama through dry residue. Deltamethrin shows the higher value of LC50 (1.256 ml) and LC95 (3.582ml) that make it less toxic to the H. itama than cypermethrin, malathion, and chlorpyrifos, however, as the concentration gets higher it becomes more toxic.
Canarium odontophyllum is a rare tropical fruit that is primarily propagated by seeds.
However, there is little information regarding its seed handling and germination. As
low seed moisture content (MC), generally that below 10%, is the key determinant to
successful seed storage while avoiding microbial damage, the objective of this study
was, hence, set to investigate C. odontophyllum’s seed germination as affected by
desiccation using drying beads (DBs) at room temperature or convection oven at
40C to varying seed MCs, from its initial MC of above 20% down to that below 10%.
It was found that the seeds tolerated fast dehydration within 24h at room temperature
using DBs. They retained 90% germination despite seed MC was reduced to below
10%. Desiccation tolerance with DBs was, however, found only with seeds extracted
from fresh fruits. As the fruits started rotting with wrinkled appearance and fungi on
the pericarp from four days after harvest onwards, the seeds extracted from them died
at MC of below 15%. A slower seed drying method using convection oven at higher
temperature of 40C, on the other hand, took 72h to bring the seed MC down to
Existing research recognizes the critical role of vocabulary in the acquisition of a second (L2)
or foreign language. In the context of L2 writing, it has been established that as vocabulary
size increases, so does the ability to write more effective texts. The purpose of this study
was to investigate the relationship between vocabulary size and ESL students’ written
performance. The participants were 69 Malaysian university students whose writing skills
were assessed as part of their English course requirement. Vocabulary size was measured
using Laufer and Nation (1990) Vocabulary Level Test (VLT). Performance on the VLT
was correlated with writing scores as a measure of written performance. Findings indicated
that a majority of participants achieved a mastery level of the 2000-word test but had
difficulty in the 3000-word and 5000-word level. Participants’ vocabulary size was also
found to be strongly associated with their written performance. These results elucidate the
importance of vocabulary knowledge in L2 writing. The pedagogical implication of the
current work calls for the integration of vocabulary in writing classrooms.
In this era of technological advancement, there is a tremendous growth in the usage of mobile applications, mainly among accounting students in higher institutions as a medium for learning tools in education. Accounting students at tertiary level basically are subjected to learn different types of accounting standards. Accounting standards have continued to evolve to strike the balance between providing meaningful information to the users and balancing up cost of preparing such information. However, there is a growing concern that financial reporting has become overly complex. The complexity caused by financial reporting standards may derive from many factors, such as their length, the difficulty in understanding them, and the cost of applying their requirements. In the educational stream, students find that it is hard to understand lengthy wordings in the standards. Therefore, this interactive application is designed to help users especially students on classification issues under MFRS140 Investment Property. Hence,the purpose of the study is to prove the practicality and usefulness of mobile apps to understand accounting standards which is known as MFRS140: Quick Chart Mobile App particularly among final semester accounting students. In this study, the results revealed that this application provides useful and precise guidelines for students as to avoid lengthy wordings to increase the level of their understanding. By using the application, users will have a better knowledge in identifying whether the land and buildings fall under MFRS140 or other MFRSs. Furthermore, the application contributes to the effort of making users learn standards of accounting in a different perspective rather than a classroom-oriented perspective.
Students’ perception and preferences on teacher-written feedback (TWF) tend to vary in different learning contexts. This study explores the perceptions and preferences of TWF among 78 Malaysian ESL students in a public pre-university college in Malaysia. Quantitative data were obtained from a questionnaire to examine the students’ general attitude and perceptions of TWF, and their preferences of the types and amount of written feedback received on their written work. This study reveals that the ESL students had a positive attitude and perception of the teacher-written feedback practice based on the perceived usefulness of the feedback, and the integrative-feedback type that combines both the content and language feedback was mostly favoured. The result also shows that the students had a high preference for indirect coded corrective feedback strategy in highlighting language errors, and preferred a large amount of feedback that highlighted all errors on their written work. These findings potentially help teachers to make a more informed decision when using teacher-written feedback so as to cater to students’ varying needs and perceptions in order to improve its use in writing.
The highest formal academic qualification is the degree of Doctor of Philosophy. Currently, in US alone, 1.77% of its population has doctorates or its equivalent degree holders. It differs in every country depending on the quality of education system that it has. As it is the highest recognition for academic performance, a lot have dreamt to hold the revered scroll. However, quite a number have failed trying. There are a lot of descriptions for the acronym PhD; the most frightening one, Permanent Head Damage. Upon reflection, one description fits well. The formula of success for obtaining PhD consists of the elements known as strategical Plan (P), the rich health (H) and the awesome determination (D). This paper is elaborating these three elements and more, required for a person who is attempting to acquire the degree based on a review of literature and my personal experiences. Hopefully, it will be able to help those who are still fighting their way through their journey.
The Silver Reed Model LK150 knitting machine is a home knitting machine which is
extremely lightweight and compact, making it preferable by most home knitters.
There are various knitwears with interesting patterns can be made using this model. In
the field of garments manufacturing by using flatbed knitting machines, it is
important to understand the physical properties of fabric so that their impact on
dimensional changes can be predicted to produce the most suitable end use. The
samples were produced by using a blended bamboo/cotton yarn, with a composition
of 30% cotton and 70% bamboo. The main objectives of this study are to to evaluate
the physical properties of single jersey fabric knitted on home knitting machine by
using different stitch dials and to relate the physical properties with different stitch
lengths. Then, all tests were conducted to compare the physical properties of samples
between three different stitch dials and the effects of before and after washing. The
physical properties measured in this research were stitch length, stitch density, weight,
thickness, absorbency and shrinkage. The result indicated that the longer the stitch
length, the higher the percentage of the water impact penetration. Meanwhile, there
was a slight reduction on the density, thickness and fabric weight. In addition, the
result after three times washing showed that the samples only had slight changes in
density, thickness, weight and stitch length, but has significant changes on the water
impact penetration.
Sabah, formerly known as North Borneo during the period of British colonisation from 1888-1963 produced many texts about the British presence and their activities on the island. This review highlights that the post-war studies especially Sabah’s colonial literature is the missing link to its alternative history. Colonial literature has left its legacy in the form of history, anthropology and art but also in the textual and literary representations of Sabah through a western lens. The critique of colonial fiction and non-fiction texts in former colonies in Malaya and Sarawak have paved the way for critical examination and commentary on the modes of representation of the indigenous and immigrants. This review discusses the highlights of postcolonial criticism in Malaysia. It briefly introduces some of the issues about postcolonial criticism in Sabah and its potential.
This study is focused on formulating a natural-based fabric softener using baking
soda and vinegar with the addition of insect repellent finish of citronella oil and
vanillin. The effectiveness of the fabric softener was evaluated by conducting a fabric
stiffness test on both untreated and treated fabric samples with the softener
formulated in this study. The assessment for the efficacy of insect repellence was
carried out using 3 human participants of the same gender and build but different
blood type, positioned at a mosquito infested area. Three tests; negative, positive, and
normal tests were conducted to evaluate the effectiveness of the formulated mosquito
repellent finishes in the fabric softener. The results show that the formulated fabric
softener is good mosquito repellent and it is good at giving a soft effect on the treated
fabric.
