Visual templates in pattern generalization activity

F.D. Rivera has written an article called Visual templates in pattern generalization activity. The article was published online in Educational Studies in Mathematics last Thursday. The study, which is described in the article, was carried out in an eighth-grade Algebra 1 class in California. Four and a half months after a teaching experiment on pattern generalization, 11 students were interviewed (clinical interviews). Clinical interviews were also made with these students directly before and after the teaching experiment. The article reports on results from the analyses of these clinical interviews.

Here is the abstract of the article:

In this research article, I present evidence of the existence of visual templates in pattern generalization activity. Such templates initially emerged from a 3-week design-driven classroom teaching experiment on pattern generalization involving linear figural patterns and were assessed for existence in a clinical interview that was conducted four and a half months after the teaching experiment using three tasks (one ambiguous, two well defined). Drawing on the clinical interviews conducted with 11 seventh- and eighth-grade students, I discuss how their visual templates have spawned at least six types of algebraic generalizations. A visual template model is also presented that illustrates the distributed and a dynamically embedded nature of pattern generalization involving the following factors: pattern goodness effect; knowledge/action effects; and the triad of stage-driven grouping, structural unit, and analogy.

Graphics calculators in examination

Roger G. Brown from the University of Leeds (UK) has written an article entitled Does the introduction of the graphics calculator into system-wide examinations lead to change in the types of mathematical skills tested? This article was published online in Educational Studies in Mathematics earlier this week. Here is the abstract of his article:

The paper reports on the introduction of the graphics calculator into three centralised examination systems, which were located in Denmark, Victoria (Australia) and the International Baccalaureate. The introduction of the graphics calculator required those responsible for writing examination questions to consider how to assess mathematical skills within this new environment. This paper illustrates the types of mathematics skills that have been assessed within the graphics-calculator-assumed environment. The analysis of the examination questions indicated that only two out of the six mathematics examinations considered demonstrated any significant change in the types of skills assessed in conjunction with the introduction of the graphics calculator. The results suggest that it is possible to reduce the use of questions assessing routine procedures (mechanical skills) with a graphics calculator, but it is also evident that there have not been major changes in the way that examination questions are written nor the mathematics skills which the questions are intended to assess.

Using live, online tutoring

Richard Lissaman, Sue de Pomerai and Sharon Tripconey have written an article that was recently published online in Teaching Mathematics and its Applications. The article is entitled Using live, online tutoring to inspire post 16 students to engage with higher level mathematics, and here is a copy of the article’s abstract:

In recent years, there has been a decline in the number of students aged 16–18 studying and being able to access higher level mathematics in schools in the UK. The Further Mathematics Network (FMN) was set up to enable access to such mathematics to all students and to promote and encourage students to study at this level. The FMN has pioneered the use of Elluminate, a well established web-based package, for live mathematics tutoring. Small groups of students meet online with an experienced tutor to learn new aspects of mathematics and to look at ways to solve complex problems. There are also extensive online resources to support the students’ learning. The findings are discussed in the following article.

Pre-service teachers’ teaching anxiety

Murat Peker has written an article about Pre-Service Teachers’ Teaching Anxiety about Mathematics and Their Learning Styles. This article was published in the last issue of Eurasia Journal of Mathematics, Science & Technology Education. A main issue in the article is the combination of focus on mathematics (teaching) anxiety and learning styles. When it comes to learning styles, Peker very much builds upon the theories of Kolb (see p. 337). The theoretical overview is quite interesting, and in many respects new to me.

The study included 506 pre-service teachers from Turkey, and two instruments were used in the study: the Learning Style Inventory and the Mathematics Teaching Anxiety Scale (both questionnaires). The first questionnaire is derived from Kolb’s works, whereas the anxiety scale was developed by the researcher. I miss a discussion of the rationale behind the choice of methods/instruments in the study, and I think this is an important aspect of such a research article. I also think there are a couple of issues about the Learning Style Inventory that should be discussed somewhat. My main critique towards the statements from this questionnaire (as they are presented in the article) is that they appear very general. Being faced with a statement like “When I learn, I like to watch and listen”, my response would vary according to the subject and teaching/learning context I had in mind. As with research on beliefs, I think it would make more sense to investigate views that teachers (pre-service or in-service) have on teaching and learning algebra, geometry, functions etc., rather than their views on teaching and learning in general. My response to a statement like “I learn best when I am practical” would also vary a lot according to what I had in mind when giving the response. I therefore think that the questionnaire has some severe weaknesses that need to be addressed. Other than that, I think the article is interesting, and Peker obviously points to some important issues!

Abstract

The purpose of this study was to investigate the differences in the teaching anxiety of pre-service teachers in mathematics according to their learning style preferences. There were a total of 506 pre-service teachers involved in this study. Of the total, 205 were pre-service elementary school teachers, 173 were pre-service elementary mathematics teachers, and 128 were pre-service secondary mathematics teachers. In the collection of the data, the researcher employed two types of instruments: the Learning Style Inventory (LSI) and the Mathematics Teaching Anxiety Scale (MATAS). The LSI determined the participants’ learning style preference: divergent, assimilator, convergent, and accommodator. The MATAS found the participants’ mathematics teaching anxiety level. The researcher used the one-way ANOVA with α = 0.05 in the analysis of the data. The study revealed that there were statistically significant differences in mathematics teaching anxiety between
convergent and the other three types of learners: divergent, accommodator, and assimilator. The difference was in favour of convergent learners. In other words, convergent learners had less mathematics teaching anxiety than the other types of learners. The study also found that divergent learners showed the highest level of mathematics teaching anxiety.

Mathematical thinking of kindergarten boys and girls

Pnina S. Klein, Esther Adi-Japha and Simcha Hakak-Benizri have written an article called Mathematical thinking of kindergarten boys and girls: similar achievement, different contributing processes. This article was recently published online in Educational Studies in Mathematics. Here is the abstract of their article:

The objective of this study was to examine gender differences in the relations between verbal, spatial, mathematics, and teacher–child mathematics interaction variables. Kindergarten children (N = 80) were videotaped playing games that require mathematical reasoning in the presence of their teachers. The children’s mathematics, spatial, and verbal skills and the teachers’ mathematical communication were assessed. No gender differences were found between the mathematical achievements of the boys and girls, or between their verbal and spatial skills. However, mathematics performance was related to boys’ spatial reasoning and to girls’ verbal skills, suggesting that they use different processes for solving mathematical problems. Furthermore, the boys’ levels of spatial and verbal skills were not found to be related, whereas they were significantly related for girls. The mathematical communication level provided in teacher–child interactions was found to be related to girls’ but not to boys’ mathematics performance, suggesting that boys may need other forms of mathematics communication and teaching.

Several studies have focused on gender differences in mathematics education, but few have focused on gender differences with small children. The study of Klein and colleagues focus on gender differences in relation to “verbal skills, variables of spatial skills, and variables related to environmental factors, including teaching methods, quality of teaching, and mathematical communication”. Four research questions are posed in the study:

  1. “Do kindergarten boys and girls differ mathematically?
  2. Are language and spatial skills related differently to mathematics achievements of boys and girls?
  3. Do boys and girls receive different mathematical communication by their teachers?
  4. Are the patterns of correlation between instructional behavior (mediation) and mathematics achievements different for boys and girls?”

A test called KeyMath was used to measure the mathematical thinking of a selection of children (n=80), half of the children were boys/girls. The test is supposed to cover an age range of 4.6-21 years. There are several subtests within this set of measures. Three tests were used to evaluate the verbal ability of the children, and two were used to evaluate their spatial skills. Observations of mathematical communications in teacher-child interactions were also made in the kindergartens. The actual testing was carried out by the authors of the paper.

The results of the study are quite interesting. They did not find any differences in mathematical achievements between the boys and girls in the study. There was, however, significant gender differences in some of the factors that were related to these results. As they state: “The boys’ mathematical achievement was significantly related to their spatial reasoning, whereas the girls’ mathematical achievement was related to their verbal skills.”

I find this study interesting in many ways, but there are a few issues that I would have liked to learn more about (and that the article does not address):

  • Were the measures translated from English into Hebrew? (If so, I would like to learn more about this process)
  • What are the reasons for deciding on this particular method, and using these particular measures, in the study?

Teachers’ metacognitive and heuristic approaches to word problem solving

Fien Depaepe, Erik De Corte and Lieven Verschaffel have written an interesting article about Teachers’ metacognitive and heuristic approaches to word problem solving: analysis and impact on students’ beliefs and performance. The article was published online in ZDM last Friday. Here is the abstract of their article:

We conducted a 7-month video-based study in two sixth-grade classrooms focusing on teachers’ metacognitive and heuristic approaches to problem solving. All problem-solving lessons were analysed regarding the extent to which teachers implemented a metacognitive model and addressed a set of eight heuristics. We observed clear differences between both teachers’ instructional approaches. Besides, we examined teachers’ and students’ beliefs about the degree to which metacognitive and heuristic skills were addressed in their classrooms and observed that participants’ beliefs were overall in line with our observations of teachers’ instructional approaches. In addition, we investigated how students’ problem-solving skills developed as a result of teachers’ instructional approaches. A positive relationship between students’ spontaneous application of heuristics to solve non-routine word problems and teachers’ references to these skills in their problem-solving lessons was found. However, this increase in the application of heuristics did not result in students’ better performance on these non-routine word problems.

Mathematics and positive sciences

On Friday, a new article by Giorgio T. Bagni was released from Educational Studies in Mathematics. The article is entitled Mathematics and positive sciences: a reflection following Heidegger. Bagni takes Heidegger‘s Being and Time as a starting point in an examination of Heidegger’s ideas about sciences in general and mathematics in particular. Here is the abstract of Bagni’s article:

In this article, I make a case for the inputs that Martin Heidegger’s theoretical perspective offers to current concerns about the nature of mathematics, its teaching and learning, and the problem of subjectivity. In particular, I consider Heidegger’s notion of positive science and discuss both its applicability to mathematics and its importance to mathematics education. I argue that Heidegger’s ontological position is consonant with some sociocultural approaches in mathematics education and that Heidegger’s work can shed some light on the problem of knowing and being. Finally, I raise some questions concerning subjectivity and the link between language and mathematical objects.
