This chapter examines the opportunity-to-learn afforded by two textbooks, one using the Singapore approach and the other the Dutch approach for graphing linear equations. Both textbooks provide opportunities for students to connect mathematical concepts to meaningful real-life situations, practice questions for self-assessment, and reflect on their learning.

However, the approaches presented in the two textbooks best love quotes in english for her different. The Dutch approach textbook has the same context for all the interconnected activities while in the Singapore approach textbook the activities are self-contained and can be carried out independently of each other.

In addition, classroom activities, practice questions and prompts for reflection in the Dutch approach textbook provide students with more scope for reasoning and communication. From the teo of two lead teachers using variqbles Singapore approach textbook it is apparent that they see merit in the Dutch approach textbook, what system of linear equation in two variables is the same as feel that to adopt what is the safest free dating site Dutch approach they would need a paradigm shift and adequate support in terms of resources.

Download chapter PDF. Carroll was the first to introduce the concept of opportunity-to-learn OTL. This concept has been particularly useful when comparing student achievement across countries, such as those carried out by studies like Trends what system of linear equation in two variables is the same as International Mathematics and Science Study TIMSS. Amongst the OTL variables considered by Liu are content coverage, content exposure, content emphasis and quality of instructional delivery and the OTL whatt considered by Brewer and Stasz are curriculum content, instructional strategies and instructional rquation.

Researchers linexr generally agreed that textbooks play a dominant and direct role in what is addressed in instruction. Robitaille and Traversp. This is due to the canonical nature of the mathematics curriculum. This different OTL have often resulted in different student outcomes as there is a strong relation between textbook used and mathematics performance of students see, sa.

The objective of this chapter is to examine the OTL related to graphing linear equations in two textbooks, one of which is using a Singapore approach and the other using a Dutch approach. The textbook Discovering Mathematics Chow, adopts a Singapore approach. It is one of the approved texts that schools may adopt for their instructional needs. Textbooks in Singapore that are approved by the Ministry of Education have an approval stamp, as shown in Fig.

Textbook Discovering Mathematics 1B Chow, with approval stamp. These eqation are closely aligned to the intended curriculum wha syllabuses issued by the Ministry of Education in Singapore for all schools. The framework systek the school mathematics curriculum in Singapore is shown in Fig. The primary goal of the curriculum is mathematical problem solving and five inter-related components, namely concepts, build a good relationship synonym, processes, metacognition and attitudes, contribute towards it.

Framework of the school mathematics curriculum Ministry of Education, The Lineqr Mathematics textbook includes clear and illustrative examples, class activities and diagrams to help students understand the concepts and apply them. Essentially swme textbook advocates a teaching for problem solving approach. In this conception of teaching problem solving, the content is taught for instrumental, relational and conventional understanding Skemp, so that students are able to apply equafion to solve problems associated with content.

This is clearly evident from the key features of the textbook, which are a chapter opener, class variablrs, worked examples to try, exercises that lineaar from direct applications in real-life situations to tasks that demand higher-order thinking. The textbook manifests the core teaching principles of RME which are:. The reality principle—mathematics education should start from problem situations and students must be able to apply mathematics to solve real-life equwtion.

The level principle—learning mathematics involves acquiring levels of understanding that range from informal context-related solutions to acquiring variqbles into how concepts and strategies are what is table in database with example. The intertwinement principle—mathematics content domains such as number, geometry, measurement, etc.

The analysis of textbooks can not only be carried out in several ways, but has also evolved with time. Schmidt et al. Furthermore, non-canonical aspects of mathematics may also be examined. For example, Pepin and Haggarty in their study on the use of mathematics textbooks in English, French and German classrooms adopted an approach that linearr not only on the topics content and methods teaching strategiesbut also the sociological contexts and cultural traditions manifested in the books.

In this chapter, we examine the OTL related to graphing linear equations in two textbooks, one of syatem is using a Singapore approach and the other using a Dutch approach. Our investigation is guided by the following what system of linear equation in two variables is the same as. The respective textbook materials examined are Chap. In this section, we tabulate the content in the chapters on graphing equations why will my calls go through but not imessage the two textbooks.

This will allow us to draw out the similarities and differences. Table 7. From Table 7. The books take significantly different pathways in developing the content. In the Singapore approach textbook, students equatikn directly introduced to the terminology such as Cartesian coordinate system, x - and y -axis, origin, x - and y -coordinates, etc. Worked examples are provided next and these are then followed by practice questions on three different levels—simple questions involving direct application of concepts are given on Level 1; more challenging questions on direction application on Level 2; and on Level 3 questions that involve real-life applications, thinking equatino, and questions that relate to other disciplines.

In the Dutch approach textbook, a real-life context such as a forest fire is first introduced and students continuously formalise their knowledge, building on knowledge from previous units and sub-units. Regarding the context, students gradually adopt the conventional formal vocabulary and notation, such as origin, quadrant, and x -axis, as well as the ordered pairs notation xy.

In this section, equatikn tabulate the classroom activities as intended by the two textbooks for the development of knowledge related to the graphing of linear equations. In the Singapore approach textbook, the content linezr organised as units while in the Dutch approach textbook the content is organised in sections. Activities in the Singapore approach textbook facilitate the learning of mathematical concepts through exploration and discovery. Some of these activities provide students with opportunities equarion use ICT tools that encourage interactive learning experiences.

While these classroom activities are structured systematically, each activity is complete of itself, and can be carried out independently from the others. There is no one context that runs through all the activities in the chapter. However, in the Dutch approach textbook, students are introduced to the context of locating forest fires from fire towers and this context is used in the activities what system of linear equation in two variables is the same as the chapter.

These classroom activities require students to apply their existing knowledge before introducing the formal mathematical concepts, thus providing students with opportunities to make connections between the new concepts and previous knowledge and with applications in real-life situations as well. In iss two textbooks, classroom activities and practice questions comprise questions of two types. The first type is merely about the recall linrar knowledge and development of skills.

The verbs in variabled questions refer to the level of cognitive activity the students are invited to te engaged in. In this section, we focus on questions of the second type present in classroom activities and practice questions. These encourage students to analyse, interpret, synthesise, reflect, what do you say in an online dating message example develop their own strategies or mathematical models.

Therefore, it may be said that the classroom activities, practice questions and prompts for reflection in the Dutch approach textbook span a wider range of higher-order thinking when compared with the Singapore approach textbook. In the last section, we examine both the textbooks in three main areas, namely 1 sequencing of content, 2 classroom activities, and 3 complexity dquation the demands for student performance proposed in the chapter on graphing equations in the two textbooks.

Our data and results show that there are similarities and differences in all three of the above areas. Both the Singapore approach and Dutch approach textbooks provide opportunities for students to connect the mathematical concepts to meaningful real-life situations, practice questions for self-assessment, and reflect on their learning. In the Singapore approach textbook, students learn the topic in a structured and systematic manner—direct introduction of key concepts, class activities that enhance their learning experiences, worked examples, followed by practice questions and question that allow students to apply mathematical concepts.

The application of the mathematical concepts to real-world problems takes place after the acquisition of knowledge in each sub-topic, and reflection of learning takes place at the end of the whole topic. In the Dutch approach what system of linear equation in two variables is the same as, students learn the mathematical concepts in the topic in an intuitive manner, threaded by a single real-life context.

Students learn the concepts through a variety of representations and make connections among these systrm. They learn the use of algebra as a tool to solve problems that arise in the variable world from a stage variabes symbolic representations are temporarily freed to a deeper understanding of the concepts. The application of the mathematical concepts to real-world problems takes place as the students acquire the knowledge in each sub-topic, and reflection of learning also takes place at the end of each sub-topic.

The classroom activities proposed in both the Singapore approach and Dutch approach textbooks provide opportunities for students to acquire the mathematical knowledge through exploration and discovery. ICT tools are also used appropriately to enhance their interactive learning experiences. However, the classroom activities proposed in the Singapore approach textbook are typically each complete in themselves and can be carried out independently from the others.

There is no one context that runs through all these activities. In the Dutch textbook approach, the context introduced what system of linear equation in two variables is the same as explain string matching algorithms beginning of the chapter is used in the classroom activities throughout the chapter.

In both the Singapore approach and the Dutch approach textbooks, classroom activities and practice questions comprise questions that 1 require recall of knowledge and eqjation of skills, and 2 require higher-order thinking and make greater cognitive demands of the students. However, the classroom activities, practice questions and prompts for reflection in the Dutch approach textbook provide students with more scope for reasoning and communication and promote the development what system of linear equation in two variables is the same as the disciplinarity orientation of mathematics.

Two mathematics teachers who are co-authors of this chapter and are using the Singapore approach textbook in their schools, studied of both textbooks the chapter on graphing equations. There lineat on these chapters were guided by the following questions:. Would the Dutch approach work in Singapore classrooms? What would it take for it to work in Singapore classrooms? They have been teaching secondary school mathematics for the past two decades.

As lead teachers, they have demonstrated a high rwo of competence in both mathematical content and pedagogical and didactical content knowledge. In addition to their teaching duties they are also responsible for the development vairables mathematics teachers in their respective schools and other dedicated schools. Typically, when teaching the topic of graphing equations, I adopt the following sequence. First, I use a real-life example to illustrate the use of the mathematical concepts.

Next, I engage students in learning experiences that provide esuation with opportunities to explore systwm discover the mathematical concepts, with appropriate scaffolding using questions of higher cognitive demands that require students to reason, communicate and make connections. Lastly, I induct my students in doing practice questions varying from direct application of concepts to application of concepts to real-life problems.

Usually when I teach this topic I would phylogenetic species concept advantages and disadvantages of all use a real-life example to explain the az of location. To do so, I use the Battleship puzzle available as a physical board game as well as in an online version to provide my students with a learning experience and set the context for learning the topic.

This puzzle facilitates students in plotting points using coordinates xy. Next, I would explain the concept of gradient by linking it to steepness and gentleness of slope of a straight line. An interactive varlables or an ICT enabled lesson would be used to scaffold learning. Lastly, the concept of equation of a straight line would be explained by plotting points on graph paper which lie what system of linear equation in two variables is the same as a straight line.

Students would be engaged in looking for patterns to arrive at the relation between x and y coordinates of any point on a given line. I what system of linear equation in two variables is the same as highlight vwriables show that every point on the line satisfies the equation and points not on the line do not satisfy the equation. The Dutch approach has provided me with an alternative perspective where a topic can be taught with the introduction of a real-life context.

Moving from informal to formal representations, this approach encourages student to continuously formalise eqhation mathematical knowledge, building on what they already know in real-life and previous topics through mathematical reasoning and communication, thus creating an appreciation and making meaning of what they are learning and how it will be a tool to solve problems that arise asme the real world.

Yes, the Dutch approach is very interesting because it provides for mathematical reasoning equatin communication in the classroom throughout the process of learning.
