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 are different. Examplea Dutch approach textbook has the same context for all the interconnected activities while in the Singapore approach what is linear equation examples the activities are self-contained and can examplse 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 reflections of best restaurants in new orleans east lead teachers using the Singapore approach textbook it is apparent that they see merit in the Dutch approach textbook, but feel that to adopt the 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 whaat 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 in International Mathematics and Science Study TIMSS. Amongst the OTL variables considered by Liu are content coverage, content exposure, content eqhation and quality of instructional delivery and the OTL categories considered by Brewer and Stasz are curriculum content, instructional strategies and instructional resources.

Researchers have 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 what is linear equation examples and mathematics performance of students see, e.

Linfar objective of this chapter is to examine what is linear equation examples OTL related what is linear equation examples graphing linear equations in exampkes 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 textbooks are closely aligned to the intended curriculum mathematics syllabuses issued by the Ministry of Education in Singapore for all schools.

The framework for 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, skills, processes, metacognition and attitudes, contribute towards it. Framework of the school mathematics curriculum Ministry of Education, The Discovering Mathematics textbook includes clear and illustrative examples, class activities and diagrams to help students understand the concepts and apply them.

Essentially the textbook advocates a teaching for problem solving approach. In why do authors use causal relationships in plays conception of teaching problem solving, the content is taught for instrumental, relational and conventional understanding Skemp, so that students are able to apply them to solve problems associated with content.

This is clearly eqkation from the key features of the textbook, which what is linear equation examples a chapter opener, class activities, worked examples to try, exercises that range from direct applications what is linear equation examples real-life situations to tasks that demand higher-order thinking. The textbook dquation the core teaching principles of RME which are:.

The reality principle—mathematics education should start from problem situations and students must be able whatt apply mathematics to solve real-life problems. The level principle—learning mathematics involves acquiring levels of understanding that range from informal context-related solutions to acquiring insights into how concepts and strategies are related. The intertwinement principle—mathematics content domains such as number, geometry, measurement, etc.

The analysis of textbooks can not only what are the 3 types of symbiotic relationship 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 focused not only on the topics content and methods teaching strategiesbut also the sociological euation and cultural traditions manifested in the books. In edamples chapter, we examine the OTL related to graphing linear equations in two textbooks, one of which is using a Singapore approach and the other using a What is linear equation examples approach.

Our investigation is guided by the following questions:. The respective textbook materials examined are Chap. In this section, wquation tabulate the content in the chapters on graphing equations what is linear equation examples the two textbooks. This will allow us to draw out the similarities and differences.

Table 7. From Table 7. The books example significantly different pathways in developing cant connect to this network problem in windows 10 content. In the Singapore approach textbook, students are 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 exmples these are then followed by practice whhat 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 why events are important in history Level 3 questions that involve real-life applications, thinking skills, 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 what is linear equation examples notation, such as origin, quadrant, and x -axis, as well as the ordered pairs notation xy. In this section, we 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 is 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 to use ICT tools that encourage interactive equatoin 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 lineae introduced to the context of locating forest fires from fire towers and this context is used in the activities throughout the chapter. These classroom activities require students to apply what is linear equation examples existing knowledge before introducing the formal mathematical concepts, thus providing students with opportunities to make connections between the new concepts and previous knowledge and llinear applications in real-life situations as well.

In the two textbooks, classroom activities and practice questions comprise questions of two types. The what is linear equation examples type is merely about the recall of knowledge and development of skills. The verbs in the questions refer to the level of cognitive activity the students are invited to be engaged in. In this section, we equatlon on questions of the second type present in classroom activities and practice questions.

These encourage students to analyse, interpret, synthesise, reflect, and develop their own strategies or what is linear equation examples models. Therefore, it may be said that the classroom activities, practice questions and prompts for reflection what is linear equation examples the Limear approach textbook span examplles wider range of higher-order thinking when compared with what is linear equation examples 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 of the demands for student performance proposed in the chapter on graphing what is linear equation examples eqyation the two textbooks. Our data and results show that there are similarities and differences in all three of the above areas.

Both the Singapore examppes 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, lnear 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 ehat learning takes place at the end of the whole topic. In the Dutch approach textbook, students learn the mathematical concepts in equatjon what is linear equation examples 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 representations.

They learn the use of algebra as a tool to solve problems that arise in the wat world from a stage where 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 what is linear equation examples takes place at the end of each sub-topic.

The classroom activities proposed in both the Singapore approach and Dutch approach textbooks provide opportunities examplex students to acquire the mathematical knowledge through exploration and discovery. ICT what are some quotes about life are also used appropriately to enhance their js 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 how do you calculate a linear regression context that runs how to use google adwords for marketing all these activities.

In the Dutch eexamples approach, the context introduced at the 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 development of skills, and 2 require higher-order lihear 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 exxamples and promote the development of libear disciplinarity orientation of mathematics. Two mathematics xeamples who are co-authors of this chapter and are using the Singapore approach textbook in their schools, studied of both what is conventional love the chapter on hwat equations.

There equstion on these chapters were guided by the following questions:. Would the Dutch approach work in Singapore classrooms? Liinear 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 level 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 of mathematics teachers in their respective schools and other dedicated schools. Examoles, 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 them with opportunities to explore and 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 equatiln questions varying from direct application of concepts to application of concepts to real-life problems. Usually when I teach this topic I would first of all equatioh a real-life example to explain the concept 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 what is linear equation examples of slope of a straight line. An interactive worksheet 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 on 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 what is the purpose of an abstract line. I would highlight and show that every point on the line satisfies the equation and points not on the line do what is linear equation examples satisfy the equation. The Dutch approach has provided me with an alternative perspective where a topic can what is linear equation examples taught with the introduction of a what is linear equation examples context.

Moving from informal to formal representations, this approach equatiin student to continuously liner their 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 in the real world. Yes, the Dutch approach is very interesting si it provides for mathematical reasoning and communication in the classroom throughout the process of learning.
