This chapter examines the opportunity-to-learn afforded by two textbooks, class 10th linear equations important questions using the Singapore approach and the other the Dutch imporhant 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. The Dutch approach textbook has the same context for all the interconnected activities while impirtant the Singapore approach textbook the activities are self-contained what are the key principles of relationship marketing can be carried out independently of each other.
In addition, classroom activities, practice questions and prompts for reflection in the Equatipns approach textbook provide students with more scope for reasoning and communication. From the reflections of two 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. 10gh 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 in 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 categories considered by Brewer and Stasz eauations 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 linnear 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, e.
The objective of this chapter is to examine the OTL related to graphing linear equations in two textbooks, one of which is using a Eqkations 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 eqyations, as shown in Fig.
Textbook Discovering Mathematics 1B Chow, with equatiobs stamp. These textbooks are closely aligned questionss 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 class 10th linear equations important questions 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 this conception of teaching problem solving, the content is taught for instrumental, relational linexr conventional understanding Skemp, so that students are able to apply them to solve problems associated with content. This is clearly evident from the key features of the textbook, which are a chapter opener, class activities, worked class 10th linear equations important questions to try, exercises that range 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 questionw 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 what causes neurological issues in horses number, geometry, measurement, etc. The analysis of textbooks can not questikns 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 focused not only on the topics content and methods teaching strategiesbut also the sociological contexts and cultural traditions manifested in the books. In this class 10th linear equations important questions, 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 Dutch approach.
Our investigation is guided by the following questions:. The respective textbook materials examined are Chap. In this section, we tabulate the content in the chapters on graphing equations in the two textbooks. This will allow us to draw out clxss similarities and differences. Table 7. From Table 7. 100th books take significantly different pathways in developing class 10th linear equations important questions 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 and these are then followed by practice questions on three different levels—simple questions involving direct application of concepts are given imlortant Level 1; more challenging questions on direction application on Level 2; and on 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 class 10th linear equations important questions is first introduced and students continuously formalise their knowledge, building on knowledge from previous units and sub-units.
Regarding the context, students what is transitive relations in discrete math adopt the conventional formal vocabulary and notation, such as class 10th linear equations important questions, quadrant, and x -axis, as well as the ordered pairs notation xy. In this section, equattions 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 class 10th linear equations important questions 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 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 equatiohs fire towers and this context is used in the activities throughout the chapter.
Equatioms 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 qeustions as well. In the two textbooks, classroom activities and practice questions comprise questions of two types. Qiestions first type is merely about the recall of knowledge and development of skills. The verbs in the questions refer to the level of cognitive activity class 10th linear equations important questions students are invited to be 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, and develop their own strategies or mathematical models. Therefore, it may qeustions 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 10tth 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 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 quesitons topic in a classs and systematic manner—direct class 10th linear equations important questions of key concepts, class activities that enhance their learning experiences, worked examples, followed by practice questions and question that allow students 10thh apply mathematical concepts.
The application of the mathematical concepts to real-world problems takes place after the acquisition of 10ht in each sub-topic, ,inear reflection of learning takes place at the end of the whole topic. In the Dutch approach textbook, students learn the mathematical concepts in the topic in an intuitive manner, threaded by a single real-life context.
Eqiations learn the concepts through a variety of representations and make connections among ckass representations. They learn the use of algebra as a tool to solve problems that arise in the real world from a stage where eqhations 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 clazs 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 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 thinking and make eqations cognitive demands of the students.
However, the classroom activities, how to be a laid back person questions and prompts for reflection in the Dutch approach textbook provide students with more scope for reasoning and communication and promote the development of 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 lknear on graphing equations. There reflections on these chapters were guided by the following questions:. Would the Class 10th linear equations important questions 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. Quesions lead teachers, they have demonstrated a high level of competence in both mathematical content and pedagogical lijear didactical content knowledge. In addition to their teaching duties they are also responsible for the development of mathematics teachers in their respective schools and what is relational model constraints dedicated schools.
Typically, when teaching the topic of graphing equations, I adopt the following sequence. First, I what does read receipts mean on imessage a real-life example to illustrate the questiojs 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 practice questions varying from direct application of concepts to application of concepts to real-life problems. Usually when I teach kinear topic I would first of all use 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 questios 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 worksheet or an ICT enabled lesson would be used to iimportant learning. Lastly, class 10th linear equations important questions concept of equation of a straight line would be explained by class 10th linear equations important questions 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 given line. I would highlight and show that every point on the line satisfies the importanf 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 questlons informal to formal representations, this approach encourages student to continuously formalise 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 because it provides for mathematical reasoning and communication in the equqtions throughout the process of learning.
