The Scientific Method

The Scientific Method

The scientific method is a detailed, empirical problem-solving process used by biologists and other scientists. This iterative approach involves formulating a question based on observation, developing a testable potential explanation for the observation (called a hypothesis), making and testing predictions based on the hypothesis, and using the findings to create new hypotheses and predictions.
Generally, predictions are tested using carefully-designed experiments. Based on the outcome of these...

Area of Science:

Public health
Health promotion
Experiential learning

Background:

Growing international interest in community and school cooking and gardening programs.
Limited empirical evidence on the effectiveness of these programs.
Need for robust evaluation frameworks to assess program impact.

Purpose of the Study:

To present the evaluation framework and methods for the Stephanie Alexander Kitchen Garden (SAKG) program.
To meet the information needs of all stakeholders involved in the SAKG program.
To address the lack of evidence on the effectiveness of school-based cooking and gardening programs.

Main Methods:

Utilized a public health ecological approach, health promotion principles, and experiential learning models.
Employed a non-randomized comparison design with six intervention and six comparison primary schools in Victoria, Australia.
Implemented a mixed-methods approach combining qualitative and quantitative data collection at baseline and 1-year follow-up.

Main Results:

The evaluation design addressed limitations in existing studies of cooking or garden programs.
The multistrand, mixed-methods approach maintained methodological rigor and explored complex findings.
Identified limited sensitivity in some quantitative measures and potential bias in qualitative data coding.

Conclusions:

The SAKG evaluation methodology offers a suitable approach for school-based kitchen garden programs.
Demonstrates the feasibility of comprehensive evaluations for school-based initiatives.
Highlights the crucial role of qualitative methods within mixed-method evaluations for stakeholder engagement.
