integration of technology in teaching science
technology-use to foster the understanding and intuitions

- teacher need to know how to manipulate technology in teaching(integrating the lesson with technology)

- technology serve as enabler for the teacher to convey the knowledge/ enabler for students to understand the teaching

-used for tutorial learning, exploratory learning / application and communication tools

- link the technology in teaching with real life experience/situation (simulation) --> teaching more meaningful

- simulation effective for teacher to give certain situation that are not accessible for the student

- data logging / data logging-interface--> objects that used for data storing.(find about it in the net)


example of data logging tool

What is data logging? As science and technology have developed, so the need for data collection and analysis has grown. This is fulfilled, at least in part, by dedicated, microprocessor-driven data loggers.

The modern data logger is typically a hand-held battery-operated device with a large memory, powered by the latest microprocessor technology and capable of acquiring, processing, storing and analyzing electrical signals at high speed from a wide range of sensors - at regular intervals or in response to an event such as a threshold being crossed or a switch being activated.


The sensors may communicate with the logger through a cable or wireless link and may sense temperature, humidity, pressure, flow, wind speed, current, voltage, resistance and a host of other physical parameters that are important in monitoring and controlling processes or conducting research.


Data stored by stand-alone data loggers is typically downloaded into a computer for more detailed analysis and reporting, though some data loggers have sophisticated on-board processing and analysis capability and can carry out some control functions such as activating an alarm or a switch.


The advantage of using a dedicated portable data logger compared to, say, a PC, is that the logger hardware and software are specifically designed for stand-alone data logging applications. This means that it is easy to connect and set up sensors and the logging system is more rugged and less power hungry, making it capable of running on batteries for longer periods of time, often in hostile environments.


The advent of wireless communication and networking means that it is possible to interrogate a logger remotely which can be extremely useful for unattended or remote applications.
