This review study synthesises 28 empirical research articles emphasising the learning of morality aspects in the context of addressing socioscientific issues (SSI) in secondary science education. The key interrelated questions we seek to address in this study are how morality is conceptualised in the science classroom in the light of emerging sustainability issues and how it can be developed. We used the Four Component Model of Morality to create a knowledge base for how morality has been conceptualised in the literature on secondary science education and how it can be developed. The findings of this review study show that not all studies have used concrete, explicit conceptualisations of morality and that the role of sense of place and the situatedness of morality have often been neglected. It also emerged that studies focusing on students' moral character and action-taking were underrepresented. We recommend that further research be carried out on the interrelationships between moral character and enacted moral reasoning. The review also reveals a gap between morality research and teaching. Based on the outcomes of this review, we propose a set of recommendations aimed at guiding and encouraging students' morality within secondary science education.

Over the past 10?years an increasing number of articles have been published in leading science education journals that report on research about teacher identity and describe interventions that support teacher identity development. My purpose in this review paper is to examine how the construct of science teacher identity has been conceptualised and studied in science education. In doing so, I synthesise the findings of 29 empirical studies on teacher identity within the field of science education in an attempt to respond to the following questions: (a) In what ways have researchers used the construct of teacher identity to examine science teacher learning and development? (b) What approaches to supporting science teacher identity development have been documented in the literature? Following that, I identify gaps and limitations in the existing literature and I offer recommendations for future research in the area of science teacher identity and identity development: (a) studying teacher identity as a process; (b) connecting science teacher identity research and reform recommendations; (c) conducting large-scale, longitudinal and life-history studies; and (d) examining teacher identity enactment in school classrooms.
