Technology is not automatically better. It is better only when the sensor and settings fit the phenomenon and the data can be verified.

Data loggers, sensors, video analysis, and smartphone apps can collect physics data.

Choose technology that measures the dependent variable directly or through a justified model.

Check calibration, zeroing, range, and resolution before collecting final data.

Sampling rate must be high enough for the time scale of the phenomenon.

Record settings, units, and export raw data in a form that can be checked.

Repair technology data-collection choices.

Evaluate a proposed data-logging setup.

Saying digital equipment is accurate without evidence.

Processing technology should make analysis clearer, not hidden. A reader must be able to trace raw data to processed data to conclusion.

Spreadsheets can calculate averages, uncertainties, gradients, and derived quantities.

Formula cells should be visible or described so calculations are reproducible.

Graphing tools should show axis labels, units, fit equation, and uncertainty treatment where relevant.

Simulations and computer models require stated assumptions and parameter values.

Technology output should be interpreted physically, not pasted without explanation.

Repair weak data-processing technology claims.

Spot Errors

Explain how technology should be used to process physics data.

Relying on software output without method.

Explain how technology should be used to process physics data.

Choose

The technology workflow is collect carefully, process transparently, and interpret physically.

Technology can support hands-on experiments, simulations, modelling, and data analysis.

For data collection, choose a suitable sensor, check calibration, sampling rate, range, and resolution.

For video or smartphone data, record the scaling, frame rate, app settings, and method.

For processing, keep formulas, graph fits, and model assumptions transparent.

Final interpretation should link technology output back to the research question and uncertainty.

Match each technology cue to its role.
