The aim of this survey study is to capitalize our previous research and examine how teaching relates to Finnish secondary school students’ liking of, self-concept in and experienced utility of genetics, attitude towards gene technology and belief in genetic determinism. In this unique setting, we used as explanatory variables their teachers’ teaching emphases and learning materials, and as student-related factors, we used gender and the number of biology courses attended. Item-response theory with exploratory, confirmatory, and explanatory analyses were carried out to model the data. Teaching explained students’ attitudes and beliefs: if the teacher’s emphasis… Continue Reading →

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: Abstract Recent reforms in science education highlight the need for student-centred approaches to teaching in school curriculum policy in South Africa. Science teachers are required to move away from traditional teacher-centred practices which regard students as mere passive recipients of knowledge. In this study, we examine classroom talk for the type of student participation encouraging moves employed in lessons on basic genetics concepts and the related quality of instructional strategies employed by a university lecturer during a semester course on genetics. A key feature of the course was the lecturer’s use of students’ prior knowledge including alternative conceptions from a diagnostic assessment to facilitate the learning of pertinent genetics terminologies. Through a qualitative approach, we combine two recently published frameworks—the… Continue Reading →
