Difficulties Experienced By Year 10 Students When Solving Monohybrid Autosomal And X-Linked Genetic Problems, Christina Williams Jan 1995

Difficulties Experienced By Year 10 Students When Solving Monohybrid Autosomal And X-Linked Genetic Problems, Christina Williams

Theses : Honours

Genetics is an important aspect of secondary education as it improves students, understanding of the inheritance of genetic diseases which are present in many families. Genetics also provides opportunities for students to learn important problem solving skills. Students experience difficulties with problem solving in genetics as they tend to rote learn algorithmic methods and not have a meaningful understanding of the concepts of meiosis, gametes and fertilisation which underpin genetics problems. Following instruction in the area of genetics, think-aloud protocols were collected from 20 Year 10 students, while solving four genetic problems. The students were also interviewed to probe their …


Identifying The Difficulties Experienced By Year 10 High School Students When Attempting To Solve Genetic Pedigree Problems, Richard Hamilton-Brown Jan 1995

Identifying The Difficulties Experienced By Year 10 High School Students When Attempting To Solve Genetic Pedigree Problems, Richard Hamilton-Brown

Theses : Honours

Teachers rate genetics as one of the most difficult biology topics for high school students to understand (Finley, Stewart & Yarroch, 1982). It has been observed that some students are able to solve genetics problems using routine algorithmic methods, without understanding the basic underlying concepts (Stewart, 1982). The aim of this study was to identify the procedural errors and conceptual misunderstandings that the students had when attempting to solve genetic pedigree problems. Genetic pedigrees are diagrammatic representations of the members and ancestral relationships in a family (Cummings, 1991). Two male and two female students were selected from each of four …
