Informal science learning has been proven to have effects on a variety of science learning outcomes. This study explored the direct and indirect influence of both prior and current informal science learning on science performance by using data from the Programme for International Student Assessment 2015. More than ten kinds of informal science learning activities were measured. Multi-level structural equation modelling was used to investigate the mediating role of science interest and self-efficacy in the relationship between informal science learning and science performance in the United Kingdom, Hong Kong, and South Korea. The results showed that prior informal science learning has a positive effect on current informal science learning and a direct influence on science performance. In addition, informal science learning significantly influenced science performance through science interest and self-efficacy. These results were consistent across three countries or regions with different cultures and science learning conditions even after controlling for background variables at student and school level.

Self-regulated learning (SRL) is of great importance to academic achievement and life-long learning. This study aimed to examine the prediction of three processes of primary students' SRL using students' prior achievement, interest in mathematics, personal best goal orientation, and their perceptions of teachers' feedback one academic year earlier. The SRL processes were planning, monitoring, and adaptive reactions. The sample comprised 2972 (1608 females and 1364 males) primary school students in Hong Kong. Multi-level path analysis determined that prior achievement, interest in mathematics, personal best goal orientation, and feedback predicted students' planning, monitoring, and adaptive reactions after one academic year, with interest and personal best goal orientation being the strongest predictors. Strategies for promoting interest in mathematics and developing personal best goal orientation among primary school students are discussed in the article. Copyright © 2018 Informa UK Limited, trading as Taylor & Francis Group.
