Livni-Alcasid, Gur A.; Haskel-Ittah, Michal; Yarden, Anat – Education Sciences, 2018
In genetics education, symbols are used for alleles to visualize them and to explain probabilities of progeny and inheritance paradigms. In this study, we identified symbol systems used in genetics textbooks and the justifications provided for changes in the symbol systems. Moreover, we wanted to understand how students justify the use of…

Dorling, Danny; Tomlinson, Sally – Journal for Critical Education Policy Studies, 2016
The old myth about the ability and variability of potential in children is a comforting myth, for those who are uneasy with the degree of inequality they see and would rather seek to justify it than confront it. The myth of inherent potential helps some explain to themselves why they are privileged. Extend the myth to believe in inherited ability…

Ibanez-Orcajo, M. Teresa; Martinez-Aznar, M. Mercedes – International Journal of Science Education, 2007
Numerous investigations show that most school science teaching, in Spain and elsewhere, implicitly transmits an inductivist and very stereotyped view of science and conveys an unrealistic image of scientific work. We present some results of an investigation with fourth-level Spanish secondary education students (15 year olds) who were taught…

Orcajo, Teresa Ibanez; Aznar, Mercedes Martinez – International Journal of Science Education, 2005
This paper presents the results of part of an investigation carried out with fourth-level Spanish secondary education students (15 years old), in which we implemented a teaching unit based on problem-solving methodology as an investigation to teach genetics and human inheritance curricular contents. By solving open problems, the students…

Jimenez-Aleixandre, M. Pilar; Bugallo-Rodriguez, Anxela – 1997
This paper reports on a case study focusing on the development of students' capacity to develop and assess arguments in the context of instruction in high school genetics. It is part of a wider project whose goals were: (1) the identification of the conditions for argument (and in general scientific reasoning) to occur in science classrooms; (2)…

Aznar, Mercedes Martinez; Orcajo, Teresa Ibanez – International Journal of Science Education, 2005
A teaching unit on genetics and human inheritance using problem-solving methodology was undertaken with fourth-level Spanish Secondary Education students (15 year olds). The goal was to study certain aspects of the students' learning process (concepts, procedures and attitude) when using this methodology in the school environment. The change…
