Learning mathematics—letting the pupils have their say

Pupil voice is an emerging force for change and improvement in many UK schools, but what is not fully understood is how best to access pupil voice within the specific context of secondary mathematics departments. This paper presents a research project designed to use pupils as co-researchers in increasing knowledge about how to improve learning in mathematics. Pupils within the school were selected and trained as “Ambassadors” to understand and disseminate innovative ways of learning mathematics into their school environment and to act to allow the voice of all the pupils in their year group to be heard. The project was intended both to raise the pupils’ awareness of how learning mathematics could be different and to enable them to voice their newly informed opinions about how best they learned mathematics. The pupils’ current feelings about the way that they were taught mathematics were explored, but the focus of the project was on enabling the pupils to make informed decisions about how they felt their learning could be improved. The pupils’ awareness of different ways of learning mathematics was raised by introducing them to alternative teaching approaches. The data generated were initially analysed by the pupils themselves in order to inform their teachers about their views and subsequently constant comparison analysis resulted in the outcomes reported here. The outcomes indicate that the students could have an important role in enabling schools to develop their teaching and improve their pupils’ mathematical learning when that voice is both informed and authorised.     

Effect of pupil factor on mathematics achievement in cambodian urban primary school

It is generally observed in the literature of school effectiveness research that there are two broadly categorized factors influencing pupil achievement. However, the results of the studies based on empirically collected data vary from country to country and from time to time. Premised on this inconsistency of results and gaps in knowledge of this field in Cambodian education, this study was conducted in order to examine the effect of pupil factor on their mathematics achievement. The data were collected from pupils by means of questionnaires and a mathematics test. After controlling such factors as pupils’ poverty during the research design, the results of the step wise regression analysis showed that pupils’ interest in mathematics was a significantly positive contributor to their performance. Pupils’ absence frequency, gender, grade repetition and preschool attendance had significantly negative effects on their mathematics outcome.     

Ability Grouping: year group differences in self‐concept and attitudes of secondary school pupils

The vast international literature on the effects of different types of ability grouping on self‐concept and pupils' attitudes towards school has focused on pupils from single year groups. This article aimed to explore year group differences in pupils' self‐concept and attitudes towards school as influenced by ability grouping. The study was cross‐sectional in design and measured attitudes towards school and mathematics, general and school self‐concept and preferences for different kinds of grouping in 234 pupils from years 7 through 10 attending a mixed comprehensive school. The findings indicated that mathematics self‐concept was consistently lower than school and general self‐concept; all aspects of self‐concept increased up to Year 9 and then declined in Year 10, pupils in the higher sets tended to have higher self‐concepts; pupil preferences for setting were greater in the higher year groups, as was the extent to which the top set was perceived to be the best. A substantial proportion of pupils wanted to move set, usually to a higher set. Set placement itself did not appear to have a consistent effect on attitudes towards mathematics. This seemed to be mediated by the quality of teaching.     

Interdisciplinary Mathematics–Physics Approaches to Teaching the Concept of Angle in Elementary School

The present study takes an interdisciplinary mathematics–physics approach to the acquisition of the concept of angle by children in Grades 3–5. This paper first presents the theoretical framework we developed, then we analyse the concept of angle and the difficulties pupils have with it. Finally, we report three experimental physics‐based teaching sequences tested in three classrooms. We showed that at the end of each teaching sequence the pupils had a good grasp of the concept of angle, they had truly appropriated the physics knowledge at play, and many pupils are enable to successfully grasp new physics situations in which the angle plays a highly meaningful role. Using a physics framework to introduce angles in problem situations is then pertinent: by interrelating different spaces, pupils were able to acquire skills in the domains of mathematics, physics, and modelling. In conclusion, we discuss the respective merits of each problem situation proposed.

Elementary school mathematics teachers’ perception of their professional needs

This study explored Israeli elementary school mathematics teachers’ perceptions of their professional needs, with the purpose of developing in-service training courses which cater to these needs. Eighty-four teachers responded to the questionnaire and were interviewed. The results indicate that the respondents’ main needs are associated with strengthening their didactical knowledge capability of dealing with emotional aspects that relate to pupils’ learning of mathematics. Although most of the respondents lack formal mathematics education, they attribute less importance to their need to enhance knowledge in the field. In light of Israeli pupils’ relatively low attainments in mathematics, the authors believe that the education system should require teachers to expand their mathematics knowledge and that only teachers with appropriate knowledge will be permitted to teach the discipline.
