Brief Summary

In 2012, the Kids University for Cooking Foundation BV has developed a nutrition education programme called 'Kokkerelli Learning Street'. This innovative programme aims to teach primary school students from study years 5-8 where food comes from, how it is processed, and how it can be used for the preparation of a healthy meal.

The Kokkerelli Learning Street is offered to primary school children in the region of Venlo, the Netherlands. The present study will investigate the effects of the Kokkerelli Learning Street on several determinants of children's fruit and vegetable intake. Based on the literature and the aims of the Learning Street, five relevant determinants are selected: (i) knowledge; (ii) taste preferences; (iii) intention; (iv) skills; and (v) attitude.

Using child-reported questionnaires, the present study aims to answer the following key questions:

What are the short-term and longer-term effects of the Kokkerelli Learning Street on children's:

• Knowledge regarding fruit and vegetable consumption?
• Intentions regarding fruit and vegetable consumption?
• Attitude regarding fruit and vegetable consumption?
• Liking of fruit and vegetables?
• Skills regarding fruit and vegetable preparation?
• Fruit and vegetable intake?

Detailed Description

In 2012, the Kids University for Cooking Foundation BV has developed a nutrition education programme called 'Kokkerelli Learning Street'. This innovative programme aims to teach primary school students aged 8-12 years (study years 5-8) where food comes from, how it is processed, and how it can be used for the preparation of a healthy meal. The theoretical foundation of the Learning Street is based on the EnRG framework, which states that behaviour is influenced both by conscious and unconscious processes. These processes can (in)directly be influenced by environmental factors. In addition, several behavioural and personal factors are thought to moderate the causal path.

The Kokkerelli Learning Street is offered to primary school children in the region of Venlo, the Netherlands. It involves education based on concepts of the Self-Determination Theory, active learning, and imagineering (e.g., self-experience in an interactive environment, rather than conventional education). The present study will investigate the effects of the Kokkerelli Learning Street on several determinants of children's fruit and vegetable intake. Based on the EnRG framework, other literature and the aims of the Learning Street, five relevant determinants are selected: (i) knowledge; (ii) taste preferences; (iii) intention; (iv) skills; and (v) attitude.

Using child-reported questionnaires, the present study aims to answer the following key questions:

What are the short-term and longer-term effects of the Kokkerelli Learning Street on children's:

• Knowledge regarding fruit and vegetable consumption?
• Intentions regarding fruit and vegetable consumption?
• Attitude regarding fruit and vegetable consumption?
• Liking of fruit and vegetables?
• Skills regarding fruit and vegetable preparation?
• Fruit and vegetable intake?

Study Groups

Kokkerelli Learning Street

The classes included in this group will participate in the Kokkerelli Learning Street; a school-based nutrition education programme included classroom-based lessons, a visit to a grower's farm and a cooking workshop.

Group Type: EXPERIMENTAL

Kokkerelli Learning Street

Intervention Type: BEHAVIORAL

The Kokkerelli Learning Street focusses on one specific food product (kale, tomato, asparagus, pepper, strawberry, blue berry, mushroom, carrot, or leek) and consists of multiple components:

1. An introduction lesson at school. Children are introduced to the product and familiarised with growing and harvesting processes and the importance of the product regarding health.

2. A visit to a grower's farm during which children are introduced to the precise planting, growing and harvesting procedures of the product. Children are allowed to enter the facilities (e.g., the greenhouse) and observe and experience the farming of the product.

3. A cooking workshop at the facilities of Kids University for Cooking BV. Children prepare a meal with help of volunteers. After preparing the meal, children help to set the table and consume their self-prepared meal.

4. An evaluation lesson at school. Children evaluate the Learning Street together with their peers and teacher.

Control group

The classes included in this group will not participate in the Kokkerelli Learning Street and will continue with their regular curriculum.

Group Type: NO_INTERVENTION

No interventions assigned to this group
