The use of chemistry learning materials within the pre-learning strategy: findings from a teachers' survey

Abstract

The pre-learning strategy includes activities oriented at students’ preparation prior to the class. Using such activities increases the pre-knowledge level which allows linking new information with the existing knowledge more efficiently and consequently reduces working memory overload. Research results indicate frequent use of various learning materials within the frame of the pre-learning strategy. The main purpose of this research is to determine the frequency of chemistry learning materials (CLMs) use within the frame of the pre-learning strategy in Croatian secondary schools. The quantitative descriptive survey research was conducted on a sample consisting of 77 high-school chemistry teachers and 62 vocational school chemistry teachers from all regions in Croatia. Data were collected through an online questionnaire and processed with descriptive and inferential statistics. According to the obtained results, it is most common that teachers use their own materials (Word, PowerPoint) and text/image chemistry learning materials for students’ preparation prior to the chemistry class. Audio-materials (podcasts), audiovisual materials (screencasts) and digital materials are represented insufficiently. The frequency of use of chemistry learning materials does not differ between high-school and vocational school chemistry teachers’.
