Week 6: We are in the lab !

This week is quite interesting because it is more on the application of Micro-computer based laboratory (MBL).


My group chose to use the data logger in this lab. A data logger (also datalogger or data recorder) is an electronic device that records data over time or in relation to location either with a built in instrument or sensor or via external instruments and sensors. They generally are small, battery powered, portable, and equipped with a microprocessor, internal memory for data storage, and sensors. Some data loggers interface with a personal computer and utilize software to activate the data logger and view and analyze the collected data, while others have a local interface device (keypad, LCD) and can be used as a stand-alone device.





We used this data logger for measuring temperature, which is one of its applications. We used data logger to measure the body and room temperature. This has been a new technology for us because we used to measure temperature using thermometer. What makes this tool more sophisticated is that it is able to convert the temperature recorded into table. From there, it provides the information about the temperature of different mediums.


In terms of application in classroom, I think that teacher can use it for teaching primary school students. This takes into consideration of the procedures involved in using this tool. For example, students just need to use the temperature probe to measure the temperature and the software will help them to record the data (temperature readings).


Advantages of using this application:

1- This data logger is easy to handle and it is not dangerous for students when using it. They just need to use the probe to measure the temperature.

2- Data logger provides accurate measurement. This will be easier for students as they do not need to manually calculate the information gathered. This data logger helps them to get the readings and it is able to convert the readings into table form


Disadvantages of this data logger:

1- This kind of tool is used by connecting it to the computers. Therefore, it would be a disadvantage if there is a limited computer facility. It would also be a problem if there are not enough probes to be used by students.

2- Considering the application in classroom, I think it is not applicable if the students are assigned to use this tool in groups. This is because some students might refuse to participate when they are in groups.


In conclusion, this data logger is suitable for to be used in teaching primary school students. In my opinion, by considering the problems which might be faced by students, teachers would be able to overcome those problems and use this application to enhance students learning in science subject.
