Reflection of this course
Assalamualaikum and good afternoon everybody . .
How are you today? I hope you are always in the pink of health. Here I want to jot reflections along my memorial journey in this course. First of all, thanks to Allah because give me opportunity and chance to face this course in this 5th semester, Alhamdulillah.
For the lab learning, I have learn so many things such as crop picture with Microsoft Paint, make video with Window Movie Maker, What is data logging?, and the uses of interactive whiteboard in classroom. All of the lab learning outputs are so interesting and I have apply them in my assignments almost. Past few years, I never know how to cropping picture, how to make an interesting and adore video, but lately I have all those experience to make it use in my life. Seriously I say that I really insane to make a new video everyday using Window Movie Maker. It really give me a positive impact to improvise my self to produce a better and good video day by day. Thanks to En.Azmi for those knowledge that has been teach to me. For the cropping picture with Paint, I do explore many application in it. Thus, I have produce an interesting edited picture from the Paint. Anyone here do know about interactive whiteboard?? I guess not all of you ever know about that. An interactive whiteboard is a piece of hardware that looks much like a standard whiteboard but it connects to a computer and a projector in the classroom to make a very powerful tool. When connected, the interactive whiteboard becomes a giant, touch-sensitive version of the computer screen. You can control your computer through the interactive whiteboard screen just by touching it with a special pen. I do experience using the interactive whiteboard during my primary school time in standard 2, 13 years ago. How very lucky am I ! Now we move on to the data logging. Actually, what is the data logging? Data logging is the process whereby physical data for example temperature, humidity, motion, pressure or light is collected using electronic sensor, which are usually built in to a device known as a data logger. The data is then downloaded from the data logger and stored to a computer or other hardware such as laptop, personal digital assistant (PDA), or graphics calculator. Specialized software programs enable this data to be displayed on a computer or other hardware in the fort of charts, graphs, and tables. It is also possible to open these collected data files in a spreadsheets program as tab delimited text or the more common CSV (comma separated values) figures. I also do apply this data logging in my data logging assignment. Quite interesting to know more about data logging that will be applied in our daily life indeed.
In this course, I do have to complete so many assignments like Problem Based Learning (PBL), What is Smart School, Application on STELLA software, and making a video about Biology Project. According to my PBL assignment, I do choose problem that related to the effect by the lacking of technician in school. There are so many effects that i have discover by the lacking of technician in school. For further reading, just go through my assignment page. Same goes to the Smart School assignment, I do learn what is the components that contribute to a Smart School. Besides, I also have lean about STELLA software. What is STELLA all about ?? STELLA actually is an interactive software that will make your teaching and learning become more exciting. Education and research are most interesting when they move out of the lecture hall and provide opportunity to create, experience, and see. STELLA offers a practical way to dynamically visualize and communicate how complex systems and ideas really work. Lastly, I have making a video according to Biology Project which is a visit to Roti Babu Warisan near in Slim River on how to make a delicious bread without any preservatives used. It such a very golden precious time there to know the process of bread making from the beginning to the end.
Last but not least, I do discover the education philosophy in Malaysia, and I have my own teaching philosophy. To read all those philosophies, just go through my philosophy page. Sincerely I say that I have gain much more precious knowledge in this SSI 3013 course. InsyaAllah, I will apply all this knowledge during my practical semester soon. To be a capable teacher is not an easy work. We have to work from our deeply heart to teach all the new generation soon.
Sincerely,
Miss Nur Fatin Afiqah Kamaruzaman

What is an interactive whiteboard ??
 |
| Interactive whiteboard in school |
Instead of using the mouse, you can control your computer through the interactive whiteboard screen just by touching it with a special pen (or, on some types of boards, with your finger). Anything that can be accessed from your computer can be accessed and displayed on the interactive whiteboard, for example Word documents, PowerPoint presentations, photographs, websites or online materials.
Using special software included with the interactive whiteboard, you can also interact with images and text projected on the board: rearranging them, changing their size, colour, etc. This offers a much more interactive experience than using a standard whiteboard or using a data projector alone.
What is Data Logging ??
 |
| Data Logging . . . |
Data logging is the process whereby physical data for example temperature, humidity, motion, pressure or light is collected using electronic sensor, which are usually built in to a device known as a data logger. The data is then downloaded from the data logger and stored to a computer or other hardware such as laptop, personal digital assistant (PDA), or graphics calculator. Specialized software programs enable this data to be displayed on a computer or other hardware in the fort of charts, graphs, and tables. It is also possible to open these collected data files in a spreadsheets program as tab delimited text or the more common CSV (comma separated values) figures.
Sensor
A sensor is a device that senses surrounding data which is then recorded by a datalogger.
Generally, four or more sensors are capable of being connected to a datalogger, depending
on the model. There are over 40 different sensors available, including light, temperature,
pressure, conductivity, motion, humidity, oxygen, Carbon dioxide, pH and voltage, altitude,
dew point, wind speed, and wind chill.
Data Logger
of use they generally have a minimum number of displays and controls and their portability
enables remote datalogging, i.e., logging data away from the computer. Dataloggers are
either fitted with an internal battery that is rechargeable or use regular alkaline batteries.
Some may also have external power supplies. Most data loggers store data in non-volatile
memory, which means the data will not be lost if the power supply fails. It is important to note
that low battery charge may cause some dataloggers to behave erratically. A cable or docking
station is normally provided to facilitate a connection to a computer (or other hardware).
Dataloggers can also make use of Bluetooth or Infra red communication to transfer data.
Software
datalogger to a computer (or other hardware) in order to be analysed, presented graphically
or manipulated. Software also allows the datalogger to be programmed for remote use.
Issues such as ease of use and installation, quality of graph production and analysis, data
transferral and manual input of data depend on the quality of the software.

Teaching and Learning
with Simulation and Modelling
The process of creating a
model of an existing or proposed
system in order to identify and understand those factors which control
the system and/or to predict (forecast) the future behavior of the system is
defined as simulation. The use of simulation able to educate and provide
students for exploring the interesting and implication in teaching and
learning. Simulation is something that can be played either in clinical
education, training or for experimenting. More practically, simulation can be
used to predict (forecast) the future behavior of a system, and determine
what you can do to influence that future behavior. Simulation can
be used to predict the way in which the system will evolve and respond to
its surroundings, so that you can identify any necessary changes that will help
make the system perform the way that you want it to. Simulation is a powerful
and important tool because it provides a way in which alternative designs,
plans and/or policies can be evaluated without having to experiment on a real
system, which may be prohibitively costly, time-consuming, or simply
impractical to do.
Modelling is a building representations of things in the ‘real world’ and allowing
ideas to be investigated. It is central to all activities in the process for
building or creating an artefact of some form or other. In effect, a model is a
way of expressing a particular view of an identifiable system of some kind.
Models are a means of understanding the problems involved in building
something, a component of the methods used in development activities such as
the analysis of the requirements for an artefact and the design of the
artefact.
A model is an abstraction, which allows people to
concentrate on the essentials of a (complex) problem by keeping out
non-essential details. Since there is a limit to how much a person can
understand at any one time, we build models to help in activities such as the
development of large software systems. For example, developers build different
models throughout the development process in order to verify that the eventual
software system will meet the requirements.
Predator-Prey
Relationship
Introduction
A
predator is an organism that eats another organism. The prey is the organism
which the predator eats. Predator and prey evolve together. The prey is part of
the predator’s environment, and the predator dies if it does not fit in terms
getting for food, so it evolves whatever is necessary in order to eat the prey;
speed, stealth, camouflage (to hide while approaching the prey), a good sense
of smeel, sight, or hearing (to find the prey), immunity to the prey’s poison,
poison (to kill the prey) the right kind of mouth parts or digestive system.
Besides, the predator is part of the prey’s environment and the prey dies if it
is eaten by the predator, so it evolves whatever is necessary to avoid being
eaten; speed, camouflage (to hide from the predator), a good sense of smell,
sight, or hearing (to detect the predator), thorns, and poison (to spray when
approached or bitten).
The
fastest predators are able to catch food and eat, so that they can survive and
reproduce and gradually faster predators make up more and more of the
population. It same goes to the preys, which are fastest able to escape the
predator, so they will survive and reproduce and gradually the faster preys
make up more and more of the population. An important thing to be realized is
that as both organisms become faster to adapt to their environments, their
relationship remains the same because they are both getting faster, neither
gets faster in relation to the other. This is the truly proof in all predation
relationships. Other than that, the predator-prey relationship are usually used
as a building blocks for an ecosystem. Predators hunt there prey and the preys
population goes down until the population gets small enough in size to where
the predators do not have enough prey to be hunted. The population starts to
drive down because of there is not enough food for them. Furthermore, the preys
start to grow bigger and they just keep going back and forth till some where
down the line in the populations level off.
As
in the Earth’s vast ecosystem, everything contains myraid parings of predators
and their preys are connected by the food chain. For example lynx as the
predator and the hares being as the prey. The daunting task of studying,
describing and predicting the future of any one link in the chain and
identifying its impact on the whole. Therefore, the predator-prey relationship
can be distilled down to controlable chunks with the predator-prey model.
Figure 1
To
run this simulation, first of all teacher needs to adjust the meter knob above
to a desire number of lynx harvest. For examples in this picture, the number of
lynx harvest for hares is 0, thus student will do their prediction on what type
of graph line that will produce. So as we know, if there is no harvesting
number of hares means no predation relationship between lynx and hares.
As
refer to this figure 1, there is an interaction between the lynx as the
predator and the hares as the prey in particular area. This simple
predator-prey dynamics experiment is carried out over a several years time. The
above graph shows there is no interaction between the predator and prey in an
Earth ecosystem. Here, I assume that there is no population number of preys in
the particular area because of the lacking sources of food for them to survive
well. This condition will affects on the productivity of the predators hunting
for a long lifetime. There are many factors that influence the availability source
of food for the prey such as abiotic (non-living) components like weather,
water supply, sunlight, minerals available, disease and also altitude. One of
the reasons why the preys (hares) won’t be able to survive or adapt to the
environment is maybe lack of sunlight for the crops to alive during winter
season,thus this will affect the populations of the hares and lynx
simultaneously. The crops are not be able to survive greatly during the winter
season. That is why the graph shows there is no interaction between the lynx
and hares for a several years lifetime.
The other logic reasons why the number of the
predators become constant is maybe because of they are in hibernation states.
The climate during this particular time is winter season thus; the lynx is kept
in hibernating. Both of these organisms; the predators and preys faced the same
limiting factor to overcome the interaction between them to occur. In this
ecosystem, the predator-prey relationship become stable because no interaction
between them. The predator and prey regulate the population of each other in a
cyclical manner which maintains the populations of both organisms in a dynamic equilibrium.
The winter season also contributes to the no interaction between the predator
and prey because of the lack of food sources for both of them.
Both of them are really not adapt with the winter
environment, automatically make them to live in a constant of population size
simultaneously without any predator-prey interaction. The prey will survive
peacefully without the disturbance from the predator hunting greedily. The
predator also unable to hunt for food source because of the less or small number
of prey population. The population sizes for both organisms for 0 until 60
years are just the same without changing any.
Figure
2
For
the next step is teacher needs to adjust the meter knob above to a desire
number of lynx harvest. For examples in this picture, the number of lynx
harvest for hares is 210, thus student will do their prediction on what type of
graph line that will produce. The lynx and hares start to interact each other
but not really happen in this stage.
To
survive and reproduce, individuals must obtain sufficient food sources while simultaneously avoiding becoming food for
a predator. Figure 2 above shown the different pattern of predator-prey dynamic
graphical compare to the Figure 1 previously. Here the lynx –hares study
demonstrates the role of both predator avoidance and food availability on
population sizes. The trade-off between food intake and the predator avoidance
is not easily addressed in the field, and the ecologists have turned to
mathematical models to better understand foraging behavior and predator-prey
dynamics, just the same as economists and atmospheric scientists do.
In my opinion, both of these organisms are still
practicing to adapt with the newly spring season henceforth the summer season.
As the graph state above, both of them are still not in interaction each other
because of the adaptation needs. The lynx is slowly increased in size same goes
to the hares. After they achieve the comfort state, the prey has attracted the
attention of the predator for hunting food for survival. Here I have adjusted
the size of 1 time lynx harvest for the hares to 210. The number of lynx is
changing over the several years depends on the population size of the hares. As
the predator population is smaller than the prey population, and lags behind
the prey population. In favorable conditions, when there are sufficient
resources, an increase in the prey population is closely followed by an
increase in the predator population.
However, when the prey population decreases as a
result of increasing predation or the other factors such as the spread
diseases, the predator’s food supply becomes limited and this leads to a
declined in the population of predators. I do found the mechanism which
controls the prey and predator size populations. First of all, I do notice that
the level at which the prey population starts to fluctuate. The fluctuation of
the prey wills leads either to an increasing in the size of the prey population
or to a falling in the prey population. If the prey population is increase, the
number of predator is increases also. This interaction wills a result to a
declining in the prey population indirectly that returns the prey population to
the level at which it fluctuates. In the other side, when the prey population
is decline, resulting to decreases in the predator size population. Due to this
condition, the prey population size is increase as well as the prey population
has returns to the level at which it fluctuate primarily. Predator and prey
populations cycle through time, as predators decrease the numbers of prey. Lack
of food resources in turn decrease predator abundance, and the lack of
predation pressure allow prey populations to rebound.
Figure 3
For
this third simulation, teacher needs to adjust the meter knob above to a desire
number of lynx harvest. In this picture, the number of lynx harvest for hares
is 600, thus student will do their prediction that the graph must figured with
a stiffness and declination lines to show the extreme predation occur.
Besides,
the figure 3 shows the same graphical pattern as in figure 2 previously. But, here I have adjusted the size of 1 time lynx harvest
for the hares slightly high to 600. The number of lynx is changing over the
several years depends on the population size of the hares. As the predator
population is smaller than the prey population, and lags behind the prey
population. In favorable conditions, when there are sufficient resources, an
increase in the prey population is closely followed by an increase in the
predator population.
However, when the prey population decreases as a
result of increasing predation or the other factors such as the spread
diseases, the predator’s food supply becomes limited and this leads to a
declined in the population of predators. I do found the mechanism which
controls the prey and predator size populations. First of all, I do notice that
the level at which the prey population starts to fluctuate. The fluctuation of
the prey wills leads either to an increasing in the size of the prey population
or to a falling in the prey population. If the prey population is increase, the
number of predator is increases also. This interaction wills a result to a
declining in the prey population indirectly that returns the prey population to
the level at which it fluctuates. In the other side, when the prey population
is decline, resulting to decreases in the predator size population. Due to this
condition, the prey population size is increase as well as the prey population
has returns to the level at which it fluctuate primarily. Predator and prey
populations cycle through time, as predators decrease the numbers of prey. Lack
of food resources in turn decrease predator abundance, and the lack of
predation pressure allow prey populations to rebound.
Figure 4
Last
but not least, teacher needs to adjust the meter knob above to a desire maximum
number of lynx harvest. In this picture, the number of lynx harvest for hares
is 750, thus student will do their prediction that the extreme predation occur
will be more dangerous to the hares as the prey in this relationship. As the
number predator increse, the number of prey will decline and vice verse.
In figure 4 shows the same graphical pattern as in
figure 3 but differently it has a very stiff peak in every particular year. I
have adjusted the size of 1 time lynx harvest for the hares to a very maximum
number which is 750. The number of lynx is changing over the several years
depends on the population size of the hares. As the predator population is
smaller than the prey population, and lags behind the prey population. In
favorable conditions, when there are sufficient resources, an increase in the
prey population is closely followed by an increase in the predator population.
However, when the prey population decreases as a
result of increasing predation or the other factors such as the spread
diseases, the predator’s food supply becomes limited and this leads to a
declined in the population of predators. I do found the mechanism which
controls the prey and predator size populations. First of all, I do notice that
the level at which the prey population starts to fluctuate. The fluctuation of
the prey wills leads either to an increasing in the size of the prey population
or to a falling in the prey population. If the prey population is increase, the
number of predator is increases also. This interaction wills a result to a
declining in the prey population indirectly that returns the prey population to
the level at which it fluctuates. In the other side, when the prey population
is decline, resulting to decreases in the predator size population. Due to this
condition, the prey population size is increase as well as the prey population
has returns to the level at which it fluctuate primarily. Predator and prey
populations cycle through time, as predators decrease the numbers of prey. Lack
of food resources in turn decrease predator abundance, and the lack of
predation pressure allow prey populations to rebound.
