Researches indicate that Brazil has the second largest number of students with low performance in basic mathematics, in a list of 64 countries (second report of the Organization and Economic Co-operation for Development - OECD, Paris - 02/10/2016). In relation to that, this work indicates a proposal to teach algebra in the 7th and 9th grades of Elementary School, more specifically Algebraic Expressions,1st degree Equations, 2nd degree Equations and a brief study on 3rd degree Equations, using games and concrete materials. This paper is based on studies of some theorists who wrote about the subject. Based on these studies, a theoretical basis of the contents of the theme was made, along with suggestions of several activities proposed using games and concrete materials. It’s hoped that this work will support other mathematic teachers in their daily work. We know that it’s not always possible to use this methodology due to various problems that occur in schools, but I hope that at some point it can be used. / Devido ao baixo desempenho em matemática dos estudantes de todo o Brasil, existe, atualmente, uma grande preocupação no ensino da matemática. Pesquisas indicam que o Brasil tem o segundo maior número de estudantes com baixa performance em matemática básica, em uma lista de 64 países em todo o mundo (segundo relatório da Organização para Cooperação e Desenvolvimento Econômico - OCDE, Paris-10/02/2016). Mediante a essa problemática, este trabalho vem sugerir uma proposta para ensinar a Álgebra no 7o e 9o ano do Ensino Fundamental, mais especificamente Expressões Algé- bricas, Equações do 1o grau, Equações do 2o grau e um breve estudo sobre Equações do 3 o grau, através de jogos e materiais concretos. O trabalho é fundamentado em estudos de alguns teóricos que escreveram sobre o tema. Baseados nesses estudos, foi feito uma base teórica dos conteúdos do tema, juntamente com sugestões de diversas atividades propostas utilizando jogos e materiais concretos. Espera-se que este trabalho sirva de apoio aos colegas professores de matemática no seu trabalho diário. Sabemos que nem sempre é possível usar esta metodologia, devido a vários problemas que acontecem nas escolas, mas espero que em algum momento, possa ser aproveitado.

Succé eller distraktion, ett laborativt arbetssätt : Effekterna av ett laborativt arbetssätt med konkret material / Success or a distraction, a laborative way of working : The effects of a laborative way of working with concrete materials

Norstedt, Max, Widmark, Carl January 2022 (has links)
Den traditionella matematikundervisningen dominerar fortfarande inom matematikämnet. Syftet med den här studien är att undersöka vilken inverkan en laborativ undervisning med konkret material har på elevers lärande. Syftet är också att se hur konkret material påverkar elevers motivation. Resultaten visar i huvudsak på att en laborativ undervisning med konkret material går att genomföra på olika sätt med både pedagogiska material och vardagsmaterial. Det inverkar positivt på elevers lärande i matematik samt deras motivation för ämnet. Läraren har en central roll i ett effektivt användande av laborativa arbetssätt och noggrann planering är nyckeln. Vi ser gärna en fortsatt forskning inom området då en stor del av forskningen är gammal. / The traditional way of teaching math still dominates within the mathematical education. The purpose of this study is to investigate which impact a laborative way of working with concrete materials has on pupils’ learning. The purpose is also to see how concrete materials are used to create motivation. The results mainly display that a laborative way of working with concrete materials is possible with both pedagogical materials and everyday materials. It has a positive impact on pupils’ development in math and also on their motivation towards math. The teachers have a central role in an effective use of laborative ways of working and accurate planning is key. We would like to see continued research around this subject because a many of the present studies are old

En kvalitatativ studie av lärares syfte gällande användningen med konkret material i den tidigare matematikundervisningen

Äng, Michaela January 2017 (has links)
Denna studie handlar om hur och i vilket syfte lärare använder konkret material i sin matematikundervisning. Skolverket förespråkar idag att elever ska få möjlighet att använda sig av konkret material i undervisningen inom matematik. Forskning visar att konkret material leder till en ökad förståelse hos elever vid inlärningen av matematik. Forskare menar att det är läraren som avgör hur det konkreta materialet används samt vilken effekt det får. Detta examensarbete kommer lyfta fram lärares syn på konkret material och i vilket syfte som det används. Genom kvalitativa observationer och intervjuer med lärare från fyra olika skolor inom årskurs 1, visar resultatet att samtliga lärare har en liknande syn hur materialet bör användas men att hur lärarna använder det varieras. Utifrån de intervjuer som gjorts visar det sig att alla lärarna har en ambition att använda sig av konkret material, men under observationerna var det tre av fyra som gjorde det. I praktiken visar det sig däremot att det finns begränsningar som gör att det konkreta materialet inte används så som lärarna hade velat. Utifrån den forskningen som finns menar forskare att lärare har en avgörande faktor vilken effekt det konkreta materialet får för inlärningen hos eleverna. / This study is about how and for what purpose teachers use concrete materials in mathematics. The curriculum says that students should have the opportunity to use concrete materials in math. Research shows that concrete material leads to a better understanding for students in learning of mathematics. Researchers believe that the teacher is the important key person so the material will have the right effect. This thesis will highlight teachers' views on concrete material and the purpose for why it should be used. Through qualitative observations and interviews with teachers from four schools in grades 1, shows results that all teachers have a similar view of how it should be used, but it varies in how teachers are using it. Based on the interviews conducted, it appears that the majority of teachers have an ambition to make use of concrete materials. In practice, however, there are limitations that make the concrete material is not used so that teachers had wanted. Based on the research available is it the teacher who is the crucial factor for what effect the concrete material will have for the students learning.

The Effect Of Instruction With Concrete Materials On Fourth Grade Students

Sari, Sibel 01 March 2010 (has links) (PDF)
The primary purpose of this study was to investigate the effectiveness of concrete materials on fourth grade students&rsquo / geometry achievement. The secondary purpose was to investigate their opinions and feelings about instruction with concrete materials. The study was carried out in a private school in Ankara with 32 fourth grade elementary school students. One group pretest-posttest design was used. Geometry Achievement Test was administered to collect the necessary data. The instruction with concrete materials was applied by the researcher five hours per week in 10 weeks. The data were analyzed by using one-way repeated measures analysis of variance. Also, an interview was conducted with 11 students to determine their opinions and feelings about instruction with concrete materials. The results of the study revealed that there was a statistically significant change in geometry achievement of fourth grade students who participated in the instruction with concrete materials over three time periods. In other words, there were statistically significant positive changes in students&rsquo / geometry achievement across pre-intervention and post-intervention and across pre-intervention and followup. Moreover, there was no statistically significant change in students&rsquo / achievement across post-intervention and follow-up. The other results can be deducted from the study: most of the students enjoyed the class more when concrete materials were used / some of the students became anxious when they first saw the questions in preintervention / most of the students stated that questions become easier after instruction with concrete materials / cubes and the geoboard were the most useful and most liked as perceived by the students.

Matematisk begreppsförståelse genom laborativt arbete i årskurs 4–6 : Begreppsförståelse som mål med laborativa material / Learning mathematical concepts in middle- school through use of manipulatives

Timbré, Camilla January 2017 (has links)
Den här systematiska litteraturstudien syftar till att undersöka vad forskning säger om att öka elever i årskurs 4–6 begreppsförståelse i matematik genom laborativa material och aktiviteter. Ett lärarperspektiv har antagits och studien behandlar olika faktorer som i de ingående ämnesdidaktiska artiklarna identifierats som betydelsebärande för den laborativa matematikundervisningen. Ett resultat indikerar att lärarens erfarenhet, didaktiska kunskaper och inställning till laborativa material har stor inverkan på hur materialen används i undervisningen och påverkar även elevernas möjligheter och syn på att lära sig matematik genom laborativa aktiviteter. Även olika perspektivs synsätt till att använda material i fast form i undervisningen tas upp, samt att det finns olika typer av konkreta, laborativa material. Begreppsförståelse är centralt för elevers förståelse av matematik och begreppsförmåga lyfts i Läroplanen 2011 för årskurs 4–6 fram som en av fem punkter som eleven ska få möjlighet att utveckla i olika sammanhang och situationer. Den övergripande frågan som denna systematiska litteraturstudie ämnat finna svar på är om och i så fall hur den laborativa matematiken med laborativa material kan vara ett sätt att arbeta på för att elever ska kunna nå en ökad förståelse för abstrakta begrepp. / <p>Matematik</p>

Laborativ matematik i förskoleklass - åk 3. : - Vad påverkar lärares arbetssätt? / Mathematics education with concrete materials in preschool up to the third school year. : - Which factors influence teachers way of teaching?

Baier, Caroline January 2009 (has links)
SAMMANFATTNINGArbetets syfte var att undersöka vilka faktorer det är som påverkar lärare att använda eller inte använda laborativt material i sin matematikundervisning i förskoleklass till och med årskurs 3. Laborativ matematik innebär i detta arbete matematiklektioner där lärare och elever tar hjälp av någon form av konkret material, både vardagsmaterial och pedagogiskt material för att förstå och lösa problem inom ämnesområdet matematik. Undersökningen genomfördes med hjälp av enkäter till elva lärare i förskoleklass till årskurs 3 på tre olika skolor i en och samma kommun. Resultatet visar att samtliga av de lärare som svarade, alltid eller nästan alltid använder laborativt material i sin matematikundervisning, men inom vilka matematiska områden detta sker är varierande. Varför lärare i denna undersökning använder laborativt material eller inte på en lektion påverkas inte av vilken utbildning de har eller om de har någon vidareutbildning i matematik och inte heller av hur länge lärarna har undervisat, utan detta beror enligt lärarna själva på andra faktorer så som: elevens förståelse, tron på metoden, intresse/attityd hos lärare och elevers, tid/lektionens längd och gruppstorlek. Knappt ¾ av lärarna har deltagit i någon form av vidareutbildning i matematik. Alla lärarna som svarade ansåg dock att det laborativa materialet är självklart och nödvändigt för att eleverna ska få en djupare förståelse, då materialet visuellt kan konkretisera detabstrakta i matematiken. Lärarna ansåg också att det laborativa materialet bidrar till att eleverna lär med fler sinnen och att detta i sin tur gör att kunskapen fastnar lättare, matematiken blir även roligare. / ABSTRACTThe purpose with this survey was to examine which factors that influence teachers to use or not to use manipulatives in the mathematics education in preschool up to the third school year. In this form of education pupils and teachers use some form of concrete materials, manipulatives like stones, seashells and pearls or special pedagogic materials to understand and solve mathematical problems. The examination was made with questionnaires to 11 teachers in preschool to the third school year in three different schools, in the same district, in x –city, Sweden. The result shows that all of the teachers, always or almost always, use manipulatives n their mathematics education, but it varies depending on which type of mathematics. Whether teachers in this investigation use, or not use, manipulatives in a lesson is not influenced by education or further education, neither how long they have been teaching. According to the teachers this is instead influenced by; for the pupils understanding, belief in the method, interest/attitude by the teachers and pupils, time/length of lesson, and group size. Almost ¾ of the teachers had some form of further education in mathematics. All of the teachers however considered the use of manipulatives obvious and necessary for the pupils to get a deeper understanding, as the materials visually can make the abstract part in mathematics more concrete. The teachers’ means that manipulatives contribute to that the pupils learn with more senses, and it causes the knowledge to remain more easy, it also makes mathematics education more fun.
