2 Università del Piemonte Orientale, Alessandria, Italy, francesca.martignone@uniupo.it In this paper, after a brief description of Italian National Guidelines and Evaluation System, we present and analyze two examples of standardized items focused on argumentation. The qualitative analysis is carried out by using theoretical lenses coming from studies about mathematical argumentation: in particular, we use Toulmin’s model to identify common features in the structure of these standardized items. The first results of our analysis give us the elements to reflect on the multiple-choice items structures that could be used for identifying specific aspects about argumentation and for assessing students’ skills.

Keywords: Assessment, argumentation, standardized tests.

Introduction

Since many years, mathematics education research has dealt with teaching and learning argumentation and proof (Hanna, 2007). The importance of argumentation in mathematics education was perceived also at the institutional level and has led to important changes in the orientation of different countries curricula (from primary to secondary school) all over the world.

Also, in the frameworks of the main international surveys, as IEA TIMSS and OECD PISA, argumentation is an important milestone. In the Mathematics Framework of IEA TIMSS 2019 (IEA, 2017) one of the three cognitive domains (reasoning) is described as:

Reasoning mathematically involves logical, systematic thinking. It includes intuitive and inductive reasoning based on patterns and regularities […]. Reasoning involves the ability to observe and make conjectures. It also involves making logical deductions based on specific assumptions and rules, and justifying results. (TIMSS 2019 Mathematics Framework, p. 24) As regards OECD PISA survey, in the recent version of the mathematical framework, we read:

Mathematical literacy therefore comprises two related aspects: mathematical reasoning and problem solving. Mathematical literacy plays an important role in being able to use mathematics to solve real-world problems. However, mathematical reasoning also goes beyond solving problems in the traditional sense to include making informed judgements in general about that important family of societal issues which can be addressed mathematically. It also includes making judgements about the validity of information that bombards individuals by means of considering their quantitative and logical implications. (PISA 2021, Mathematics Framework, First draft, p. 10)

In this paper we examine how Italian mathematics standardized tests try to assess specific aspects related to argumentation skills: we analyse two items selected from grade 5 (primary school) national standardized tests. We use theoretical lenses taken from research in mathematics education

(3)

in order to highlight the argumentation features that these two standardized items focused on. Our reflections are grounded in the studies on argumentation processes carried out by some Italian researchers (Boero, Garuti & Lemut, 2007; Boero, Douek, Morselli & Pedemonte, 2010; Arzarello

& Sabena, 2011).

Italian National Guideline and standardized tests

In the last ten years, new Italian National Guideline (NG) for the first cycle of instruction (i.e. pre- primary, primary and middle school) have been proposed by the Ministry of Education (Ministero dell'Istruzione, Università e Ricerca, MIUR). For primary and middle school (grades 1 to 8), the NG were first published in 2007 with the latest version arriving in 2012 (MIUR, 2012). Italian legislation does not lay down a strict curriculum, but it indicates the goals for competence development at the end of grades 3, 5 and 8.

Some of these goals refer explicitly to the argumentative skills that students should acquire:

[the student] constructs reasoning by formulating hypotheses, by supporting his/her ideas and by dealing with others’ points of view (grade 5, end of primary school, MIUR 2012, p. 50, translation by the authors)

[the student] produces arguments based on the theoretical knowledge acquired […] [the student]

supports his/her beliefs by choosing examples and counterexamples and by using concatenations of claims; [the student] agrees to change his/her opinion recognizing the logical consequences of a correct argument” (grade 8, end of middle school, MIUR 2012, p. 51, translation by the authors).

The Italian Ministry of Public Education has established the standardized assessment of the Italian educational system, and commissioned the INVALSI (www.invalsi.it) to carry out annual surveys nationwide to all students in the second and fifth grades of primary school, grade 8, and high school (grades 10 and 13). INVALSI is a research institute with the status of legal entity governed by public law. INVALSI carries out periodic and systematic checks on students knowledge and skills (about reading comprehension, grammatical knowledge and mathematical competency), and on the overall quality of the educational offers from schools and vocational training institutions; in particular, it runs the National Evaluation System (SNV). The INVALSI standardized tests were created for system evaluation and this is their primary purpose. The statistical representative sample comprises approximately 30,000 students (with tests administered under controlled conditions).

Moreover, the tests are administered at census level and students results are provided to each school institution. The SNV Framework defines what type of mathematics is assessed by the SNV tests and how it is evaluated. It identifies two dimensions along which the items are built: the mathematical content, divided into four major areas (Numbers, Space and Figures, Relations and Functions, Data and Uncertainty), and the mathematical processes involved in solving the items (Knowing, Problem Solving, Arguing and Proving). These dimensions are closely and explicitly related to the goals for competence development of NG. The framework adopted by SNV assessment includes aspects of mathematical modelling as in PISA survey (Niss, 2015), and aspects of mathematics as a body of knowledge logically consistent and systematically structured, characterized by a strong cultural unity (Arzarello, Garuti, & Ricci, 2015). The INVALSI tests are

(4)

designed by expert teachers, educational and disciplinary researchers, statisticians and experts of the school system. (Garuti & Martignone, 2015; Garuti, Lasorsa, & Pozio, 2017).

Argumentation in INVALSI tests

As stressed before, taking into account the NG suggestions, INVALSI tests aim to assess also argumentation skills. Therefore, our research questions are: which aspects related to argumentation skills can be assessed by a standardized test? And in which way? These are very general questions that we faced starting from a more specific investigation about which elements were taken into account in the construction of some INVALSI argumentative items.

In a INVALSI booklet there are approximately 40-50 items and about 10% of these are about argumentation. A standardized test cannot assess all the argumentative skills quoted in the NG (e.g.

formulating hypotheses or exploring a problem situation in order to produce conjectures), but it can propose tasks that ask students to support his/her statements, to show examples and counterexamples, and to recognize the logical consequences of a correct argument. In the SNV framework the limits of standardized tests in the assessment of mathematical competencies, particularly with regard to the argumentative skills, are well explained, but it is also clear that some aspects of this capability can be assessed. For example, by means of items that ask to choose the correct answer and the right justification of it among the options proposed, or to produce and justify the answer. In INVALSI tests, two item-format types are used to assess the argumentative skills:

open constructed-response items and selected-response (multiple-choice) items. The first may ask the student to explain how the answer was reached or to justify the answer of a given statement; the second requires to select one response among a number of options.

In this paper we analyze two multiple-choice items selected from grade 5 tests. We joined the groups of teachers and experts, who produced the INVALSI tests, therefore we can argue about the choices made during items productions. These choices are the results of discussion in which Mathematical Knowledge for Teaching (Ball, Thames, & Phelps, 2008), the experiences developed in the classrooms, and knowledge about educational research studies merged.

Any discourse cannot be accepted as an argumentation, “[…] a reason or reasons offered for or against a proposition, opinion or measure” (Webster Dictionary), and may include verbal arguments, numerical data, drawings etc. Argumentation can indicate both the process which produces a logically connected discourse about a given subject and the text produced by the process (Douek, 2007).

In order to describe the structure of mathematics argumentations, as texts produced, different studies use Toulmin’s model (1958). In the next paragraph we show some interpretative tools proposed by this model.

An interpretative tool for the argumentation structure

Toulmin’s model (1958) has been used for the analysis of arguments in mathematics education (Pedemonte, 2007) as a tool to analyses structural features of mathematics argumentation both with pre-service teachers (Arzarello & Sabena, 2011) and primary students (Douek & Scali, 2000). Many studies report the limitations of this model in order to analyze mathematical argumentation (Nielsen

(5)

2011), in particular to study the dialogical and dialectical elements of verbal interaction that take place in the classroom. The “argumentation” is much more complex that the arguments that make it up, but Toulmin’s model can be used to identify the argument structure, in particular to break down arguments into their constituent parts. In Toulmin’s basic model an argument comprises three elements: the Claim (C), i.e. the statement; the Data (D), i.e. the data that justify the claim C; and the Warrant (W), i.e. the inference rule which allows data D to be connected to claim C.

We use this way of breaking down arguments into their constituent parts to identify and compare some elements in the structure of multiple-choice options of INVALSI argumentative items.

Research questions

In our study we focus on written texts, in particular INVALSI multiple-choice items in which students have to choose among different sentences. In this frame, we refine our initial research questions: can we identify common structures in the different answer options in INVALSI tests?

How can we carry out a posteriori analysis of the argumentative items by using some interpretative tools coming from Toulmin’s model?

Examples of INVALSI argumentative items

The first example (Figure 1) is a geometry item relating to equivalence between plane figures.

Figure 1: Item from SNV 2016, grade 5 (indicating the percentage for each option) (translation by the authors)

The student must choose the correct answer: the options are built up by two “Yes” and two “No”

(6)

followed by arguments that have to justify correctly the answer. The stem consists of two figures and a question that is common in activities about geometrical objects in primary school. This example shows a structure in the construction of the item that we identified as very common in the INVALSI argumentative items. In the different options, the student has to choose not only if the answer is Yes or No, but also the correct argumentation: i.e. the argumentation that is relevant and useful to answer correctly the question. For these reasons, all the sentences after Yes and No are true sentences, but in only one is there a correct argument. In particular, options A and C (together are chosen by about the 50% of students) are both referring to the fact that the dimensions of the rectangles are different: these may refer to a misconception like "if the sizes are different then the area must be different" quite common in primary school. Option D (chosen by 7.4% of the students) is weaker and refers to invariance of shapes (right triangles). Using the Toulmin’s model to interpret the item structure, we can identify Data (D) (i.e. the representation of two equivalent rectangles made by the same triangles), Claim (C) (i.e. the recognition of the equivalence of the figures: “Yes, they have the same area” or “No, they don't have the same area”) and Warrants (W) (i.e. the inference rule which allows Data (D) to be connected to Claim (C) about the identification of the same area of the rectangles). Therefore, focusing on the structure of the four options, the students have to choose the options where they recognize both the right answer to the question about the equivalence of the figures area and the right justification of it. The second example (Figure 2) deals with a situation framed in a field of experience external to mathematics.

Figure 2: Item from SNV 2016, grade 5 (indicating the percentage for each option) (translation by the authors)

(7)

This item requires to understand that the difference in the amount of water contained in equal pitchers doesn’t change if we add the same amount of water in each one of them. The students have to recognize the correct statement that justifies this invariance. The incorrect options highlight misconceptions related to the situation of invariance or difficulties in identifying a condition that is necessary, but not sufficient. In this example, the students can identify arguments (Warrants) linked also to everyday life experience, or can use forms of reasoning for general principles about adding quantities to different initial amounts. The statistical data show that this item has a higher percentage of correct answers: we can conjecture that it is because it refers to everyday life experiences. The option B focuses on the difference between relative and absolute increase and it was chosen by many students (29.1%). In fact, the other options show more general arguments about shape and content of the pitchers.

Using the Toulmin’s model: data (D) is represented by the figure and the text of the question that describes the situation. Claim (C) is about the increase of water in the two pitchers after the addition of the same quantity of water. Warrant (W) is given by the arguments in support of responses (two for answer Yes and two for answer No). Although the mathematical content and context are very different from the previous example, we identify the same structure: all the arguments are true, but only one is adequate in order to support the correct answer.

Summarizing, the analysis of the structure of these two items show that all the Warrants are true and pertinent (i.e. relating directly) to the mathematical content of the item, but only one is adequate, that is useful to support the Claim.

Discussion

In this paper we discussed some features of INVALSI items focused on argumentation: multiple- choice items where the student has to identify the right arguments to support his/her answer concerning a given statement. Analyzing this tests, we demonstrate how certain aspects of argumentation can be assessed through the use of standardized items. In particular, the ability of the students to choose the correct argument to support a statement. We are aware that the analysis of other argumentative skills, such as the production of justifications to support a claim, requires analysis tools other than the Toulmin’s model, which provides us with information only on the structural aspects of the argumentation. By means of two examples, we show some characteristics of argumentative items and we use Toulmin’s model as a posteriori interpretative tool to describe and interpret the structure of these items. We chose Toulmin’s model as an interpretative tool because it allows us to analyze retrospectively the structural aspects of argumentative items focusing on the characteristics of the justifications (Warrant), regardless of the mathematical content involved. The analysis carried out in this paper wants to show how, even if we chose two items that deal with different topics and contexts, we can identify in the structure of the items some similar characteristics: i.e. structural characteristics that the use of Toulmin’s model can clearly highlight.

In the examples presented here all the justifications (Warrants) are true and pertinent, but in INVALSI tests we can also find items where all the justifications (Warrants) are true but only one is pertinent or items where the incorrect options are false but pertinent. In the latter case, as regards

(8)

the first example (Figure 1), the three incorrect response options could have been as follows: No, because the two figures have different areas; No, because the two figures have a different number of triangles; Yes, because the two figures are congruent. The justifications are false, but directly relevant (i.e. pertinent) to the context of the question.

It is clear that, as underlined at the very beginning of the paper, standardized items can evaluate only some features of argumentation, as well as the Toulmin’s model can identify only specific types of argumentation structures, but this doesn’t mean that a study about these elements cannot give us some educational information about the assessment on argumentation and helpful tips for designing other kinds of standardized items about argumentation. As a matter of fact, in the further steps of our study, we are investigating if the Toulmin’s model can become a useful a priori tool in order to construct items in which the argumentations have different structures: i.e. items with the same structure of those presented here; items where it is explicit that the answer is No (or Yes) and the students have to choose the only warrant that justifies it; items in which, starting from the data and by a given warrant, the students have to choose which statement, among those proposed, is justified by the argument (from Warrant to Claim).

Therefore, in our study the Toulmin's model is being transformed from a posteriori analysis tool that sheds light on the passage from Claim to Warrant (I have a Claim and I have to identify which Warrant is adequate to justify that Claim) to a tool for constructing argumentative items, that to say to a priori analysis tool.
