For linear equations, such as 3(x+1)=15, a standard algorithm exists (the first step of which is to distribute the 3; Buchbinder et al., 2015; Star & Seifert, 2006), yet there are other alternative strategies that are arguably more optimal for this particular equation, such as dividing both sides of the equation by 3 as a first step.

In order to avoid any charge of improper procedure it is desirable that the Arbitrator follows a structured procedure which is also made known to the parties. Previous studies have found that mathematics experts showed relatively consistent criteria for identifying the most elegant or situationally appropriate strategy as the best, while students held more diverse criteria; furthermore, some students also believed the standard strategy was better (as did many of the Spanish students in the present study) (Star & Madnani, 2004; Star & Newton, 2009).

No doubt that even these innovations can be challenged, but such objections are difficult to sustain unless it was proved to unfair. All equations could be solved with the following standard algorithm that is taught as an explicit component of the mathematics curriculum in Finland, Sweden, and Spain and that has been used in prior research on linear equation solving (e.g., Buchbinder et al., 2015; Rittle-Johnson & Star, 2007; Star & Seifert, 2006): First, use the distributive property to clear parentheses. estudiantes en el proceso evaluaciones, metacognitivas son en toda The advanced middle school cohort is a reasonable group to compare with the advanced high school students within and between countries, since the latter group consists, roughly speaking, of the top 20% of students in the age cohort.Footnote 4.

This study yielded important insights about flexibility and can push the field to explore the extent that within- and between-country differences in flexibility can be linked to differences in countries educational systems, teaching practices, and/or cultural norms around mathematics teaching and learning. Whether the judge or parties have flexibility to change the rules of the game is an important, but understudied, aspect of procedure. Br J Educ Psychol. As noted in a position paper on procedural fluency from the National Council of Teachers of Mathematics (NCTM, 2014): All students need to have a deep and flexible knowledge of a variety of procedures, along with an ability to make critical judgments about which procedures or strategies are appropriate for use in particular situations. Researchers have begun to investigate procedural flexibility, in mathematical domains including arithmetic (Blte et al., 2001; Shaw et al., 2020; Torbeyns et al., 2009), computational estimation (Star & Rittle-Johnson, 2009), algebra (e.g., Rittle-Johnson & Star, 2007), linear algebra (Maciejewski & Star, 2019) and calculus (Maciejewski & Star, 2016); and among American (Rittle-Johnson & Star, 2009) and international (Hst et al., 2019; Joglar et al., 2018; Xu et al., 2017) students.Footnote 1 Within this literature, procedural flexibility is defined as knowledge of multiple strategies and the ability to select the most appropriate strategy for a given problem and problem-solving circumstances (e.g., Star, 2005). Some of these possibilities seem radical, but we show that, contrary to conventional wisdom, current civil practice already permits similarly radical flexing of procedure. Epub 2016 Aug 9. Furthermore, even gifted students or mathematics content experts who have knowledge of multiple strategies do not always choose a situationally appropriate strategy (Dover & Shore, 1991; Star & Newton, 2009). https://doi.org/10.1037/0003-066X.58.1.78, Huntley, M. A., Marcus, R., Kahan, J., & Miller, J. L. (2007). Spontaneous flexibility, operationalized to be when students used a situationally appropriate strategy in the first attempt on a problem (in Phase 1), was very low across the sample (with an overall average of 0.5 problems out of 12) and virtually non-existent among Spanish students (the Spanish average across all students was 0.2; see Tables 2, 3). First, in the advanced mathematics classes, Spanish students had the highest potential flexibility both in middle school (0.9 equations) and in high school (1.1 equations).

For example, in Spain only 47 of the 246 students (19%) were in the advanced mathematics track in high school, while in Finland and Sweden, these proportions were 40% (103 of 258) and 63% (181 of 288), respectively. We believe many of these students ran out of time although some may simply not have known what to write for these problems.

In particular, it was found that Swedish mathematics teacher educators prioritized the importance of individual interaction, building on students ideas, and deriving mathematics from everyday situations, while in Finland, clarity, pedagogical routines, homework, and specific goals for every lesson were more highly valued. With respect to the case of Spain, why might Spanish students flexibility and accuracy in equation solving be so different than similarly aged students from Sweden and Finland?

Thus, if a standard algorithm has become well-practiced, a student may be able to quickly, effortlessly, and accurately implement itand thus, it may indeed be the best approach to that problem, especially in a test-like context like the Tri-Phase Flexibility Assessment used here. High school students were more accurate equation solvers than middle school students and advanced track high school students were more accurate than basic math track high school students. Martin, M.

The idea that a standard algorithm could be considered as the best approach to a problem, perhaps even better than what we refer to here as a situationally appropriate approach, has a rational basis. To the contrary, such forms of procedural flexibility may offer unexpected avenues for addressing inequities of the current status quo. 17 2 3 3 3 3 3 How does accuracy in linear equation solving vary by age (middle school vs. high school), by academic track (basic vs. advanced track), and by country (Spain, Finland, and Sweden)?

In fact, it may even be the case that Spanish teachers and students believe that standard approaches are more highly valued than the situationally appropriate approaches used in the present study. More generally, within the discipline of mathematics, mathematicians tend to believe that a situationally appropriate strategy is the one that is most elegant, despite the fact that it is often difficult to objectively define elegance (Hardy, 1940). There is some indirect evidence in support of this assumption. de los estudiantes, demostraban mucho sobre su participacin activa en el desarrollo de las sesiones de aprendizaje, Scorers began by examining students solutions produced in Phase 1i.e., those written in the space designated for each problem on the test to hold the solutions provided in Phase 1. profunda se voltea fcil con un ventarrn, de muy sumisos y pasivos, mis estudiantes despierten inters por el el cual les impacto a los estudiantes de An attempt to improve the litigation process has always been at the heart of any judicial reforms.

In particular, prior studies have consistently found that students from different countries demonstrated different types of mathematical thinking when solving problems (Cai, 2004; Jiang et al., 2014, 2017). WebMoreover, the flexibility may go under question when the standardization of the process goes beyond the reasonable. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. Similarly, and also on similar linear equations, Star and Seifert (2006) found that middle school students used situationally appropriate strategies on only 2.5 out of 19 equations (or 13.2%). importancia de un plan, hagamos nuestro plan, -La cronogramacin del tiempo no fue document.write("" + "unbound" + "@" + "law.uchicago.edu" + "<\/a>") For example, previous studies found that students from several different countries showed a strong tendency to overuse a certain type of proportional reasoning strategy to solve a set of problems and were not capable of switching amongst different strategies based on the types of problem (De Bock et al., 2002, 2007; Fernndez et al., 2012; Li et al., 2014). 3 2 3 3 3 3 3 The Journal of Mathematical Behavior, 21(4), 401421. 2019 Feb 14;10:86. doi: 10.3389/fpsyg.2019.00086. planificacin de la Four schools were located in a region with an average immigration ratio of 9% (nationally, approximately 8.7% of students in Spain are foreign immigrants) and one school in a region with 4% of immigrant students. Although the prior literature on procedural flexibility implicitly assumes that procedural flexibility is related to accurately solving mathematical tasks, there is little direct evidence in support of this relationshipand some of this evidence is mixed.

DIARIO DEL As a result, whether (and the degree that) there are cross-cultural differences in students procedural flexibility is an open question, the answer to which will be informative to efforts in many countries to promote the development of procedural flexibility as one instructional outcome. First, we generally found expected relationships between students age (middle school vs. high school) and both procedural flexibility and accuracy. Bethesda, MD 20894, Web Policies Swedish and Finnish advanced track high school students had the highest flexibility, with each exhibiting flexibility on 36% (or about 4.3) of the equations on the assessment. As noted above, previous research has not addressed how country, academic track or age are related to students procedural flexibility. para que quede en el cuaderno, entre todos Queridos alumnos, tu opinin, la seriedad y sinceridad con la que contestes nos Our data do not allow us to precisely determine the extent that this top 20% of middle school students in each countrys sample did indeed go on to take more advanced mathematics classes in subsequent years. igual forma si nosotros no conocemos nuestra Student, teacher, and instructional characteristics related to students gains in flexibility.
