Inquiry-Based Student Learning Activities for Upper Secondary School Chemistry

Nielsen, Jonathan January 2019 (has links)
Läroplanen för gymnasiets Kemi 1 och Kemi 2 förespråkar elevplanerade laboratorieövningar. Men de nuvarande populära kurslitteratur som används för att undervisa Kemi 1 och Kemi 2 beskriver primärt bara elevlaboratorier med fullständiga instruktioner för eleverna att följa. Denna litteraturstudie listar och beskriver 15 undersökande elevaktiviteter för i Kemi 1 och Kemi 2. Beskrivningen fokuserar på elevaktivitet, förutsättningar och läranderesultat. Varje aktivitet hittades i en publicerad referentgranskad artikel. Dessa 15 elevaktiviteter kan sammanlagt användas till undervisning av 11 av de 19 screenade centrala innehåll från läroplanen för Kemi 1 och Kemi 2. / The state prescribed curriculum for the two chemistry courses Kemi 1 and Kemi 2 for Swedish upper secondary school, advocates student planned laboratory exercises. But the current popular course literature book systems used for teaching Kemi 1 and Kemi 2 primarily describe student laboratory exercises with complete step-by-step instructions for the students to follow. This literature study lists and describes 15 inquiry-based learning activities for students attending Kemi 1 and Kemi 2, the descriptions focus on student activity, preconditions, and learning outcome. Each activity was found in a published peer-reviewed article. Combined these 15 student activities can be used for teaching 11 out of the 19 screened core contents listed in the state prescribed curriculum for Kemi 1 and Kemi 2.

Evaluation of a High School Science Fair Program for promoting Successful Inquiry-based Learning

Betts, Julia Nykeah 25 September 2014 (has links)
The success of inquiry-based learning (IBL) in supporting science literacy can be challenged when students encounter obstacles in the absence of proper support. This research is intended to evaluate the effectiveness of an Oregon public school district's regional science fair coaching program in promoting inquiry skills and positive attitudes toward science in participating high school students. The purpose of this study was to better understand students' perception of program support, obstacles or barriers faced by students, and potential benefits of IBL facilitated by the science fair program. Data included responses to informal and semi-structured interviews, an anonymous survey, a Skills assessment of final project displays, and an in-depth case study on three students' experiences. Results suggest that the science fair program can properly engage participants in authentic IBL. However, when assessing the participant's final project displays, I found that previous fair experience did not significantly increase mean scores as identified by the official Oregon Department of Education (ODE) scoring guides. Based on results from the case study, it is suggested that participants' low science self-concept, poor understanding of inquiry skills, and inability to engage in reflective discourse may reduce students' abilities to truly benefit. Recommendations to address this discrepancy include identifying specific needs of students through a pre–fair survey to develop more targeted support, and providing new opportunities to develop skills associated with science-self concept, understanding of inquiry and reflective discourse. In addition, results suggest that students would benefit from more financial support in the form of grants, and more connections with knowledgeable mentors.

Direct, Hands-on Or Inquiry Instruction A Study Of Instructional Sequencing And Motivation In The Science Classroom

Wiede, Jamie Vander 01 January 2011 (has links)
Currently, a debate exists between the strengths and weaknesses of direct and inquiry instruction. Inquiry instruction is related to positive effect on learner motivation whereas supporters of direct instruction point to its ability to adequately support learners’ working memories (Hmelo-Silver, Duncan, & Chinn, 2007; Kirschner, Sweller, & Clark, 2006; Kuhn, 2007; Sweller, 1988). This study examined the possibility of combining the best features of both inquiry and direct instruction by sequencing them together. A two-part lesson on electrical circuits was presented in three separate sequences of instruction to middle school students to determine if differences in student motivation and academic achievement emerge depending on whether a guided inquiry lab followed or preceded direct instruction. Results indicated equal levels of perceived competence by students across all instructional sequences and greater interest/enjoyment and perceived autonomy support when the instructional sequence began with a guided inquiry lesson. No significant differences in achievement were reported among the sequences.

Active Learning Using Model-Eliciting Activities and Inquiry-Based Learning Activities in Dynamics

Georgette, Jeffrey Phillip 01 December 2013 (has links) (PDF)
This thesis focuses on a year-long project of implementing active learning in undergraduate dynamics courses at Cal Poly San Luis Obispo from 2012-2013. The purpose is to increase conceptual understanding of critical dynamics concepts and to repair misconceptions of the students. Conceptual understanding in Dynamics is vital to understanding the big picture, building upon previous knowledge, and better understanding the behavior of engineering systems. Through various hands-on activities, students make predictions, test their conceptions, and solve real world problems. These active learning methods allow students to improve their learning of Dynamics concepts. Education research on active learning is present in Physics and Mathematics disciplines, yet is still growing in Engineering. Four Inquiry-Based Learning Activities (IBLAs) and two Model-Eliciting Activities (MEAs) are discussed in this thesis. Inquiry-Based Learning Activities feature student prediction and experimentation in which the physical world acts as the authority. On the other hand, Model-Eliciting-Activities prompt students to solve real world problems and deliver results to a client. From the results, some activities yield an increase in conceptual understanding, as measured by assessment items, while others do not yield a significant increase. These activities not only help to promote conceptual gains, but also to motivate students and offer realistic engineering contexts. In conclusion, the six total IBLA and MEAS will continue in practice and be improved in their implementation. This thesis work will contribute to engineering education research of active learning methods, and improve the undergraduate dynamics curriculum locally at Cal Poly.

Superando obstáculos no ensino e na aprendizagem da evolução biológica: o desenvolvimento da argumentação dos alunos no uso de dados como evidências da seleção natural numa sequência didática baseada em investigação / Overcoming obstacles in teaching and learning of biological evolution: the development of argumentation of students in the use of data as evidences of natural selection in a didactic sequence based on inquiry

Tonidandel, Sandra Maria Rudella 14 February 2014 (has links)
A educação científica tem se voltado para atividades pedagógicas que utilizam a prática investigativa de alunos. Um dos objetivos é que os estudantes se apropriem não apenas dos conceitos científicos, mas também das práticas específicas da atividade científica. Uma das pretensões é que os alunos desenvolvam a competência da argumentação científica. Esta investigação pretende compreender como os alunos desenvolvem sua argumentação escrita, analisando a utilização que fazem dos dados como evidências da seleção natural de forma a sustentar suas conclusões na resolução de questões investigativas sobre evolução biológica. Elaboramos uma sequência didática cuja arquitetura estabelece os alicerces para a ação pedagógica do professor e promove uma atuação investigativa dos alunos. A arquitetura da sequência tem duas bases integradoras: a) a educação científica baseada em investigação e b) a matriz de construção histórica da investigação de Darwin sobre a seleção natural como mecanismo da evolução biológica. Para investigar como seria o ensino da evolução biológica que recupera o viés da matriz investigativa utilizada por Darwin, nossa questão-problema foi construída com dois grandes focos: a) como articular intenções conceituais e metodológicas características da natureza das ciências biológicas com a abordagem dos principais obstáculos da construção histórica do conceito de seleção natural numa sequência didática baseada em investigação e b) de como é a utilização de dadosT como evidências da seleção natural na composição da estrutura argumentativa escrita de alunos de ensino médio durante a aplicação de uma Sequência de Ensino de Biologia Baseada em Investigação (SEEBI) para o ensino de evolução biológica. Para investigar nossa questão, elaboramos a SEBBI que foi aplicada por uma professora da rede pública para 125 alunos da 3ª série do ensino médio de uma escola pública estadual de São Paulo. Nossa metodologia é de abordagem qualitativa integrada a uma abordagem quantitativa. Nossos dados compõem-se de: a) materiais (apostilas, modelos experimentais, elementos audiovisuais utilizados nas aulas) e b) apostilas com respostas escritas pelos alunos após as atividades propostas. As análises foram realizadas a partir das apostilas escritas dos alunos, dos materiais elaborados e disponibilizados na SEBBI e na transcrição que realizamos. Os resultados mostram que a SEBBI tem alicerces em intenções conceituais e metodológicas características da biologia. Além disso, os resultados apontam para uma superação de obstáculos conceituais pelos alunos, como a teleologia cósmica e o fixismo, para a construção do conceito de seleção natural. Os resultados das análises apresentam uma melhora na capacidade argumentativa dos alunos, uma forte correlação entre o uso de dados de evolução biológica com a construção de argumentos de maior qualidade pelos alunos, pelo uso de justificativa (garantia e apoio) alicerçada em conhecimento científico. Há evidências da ampliação da construção de argumentos, tanto no aumento do número de componentes utilizados quanto na qualidade dos componentes campos-dependentes da ciência, como o apoio e evidências. Os argumentos construídos passam a apresentar a sustentação baseada em apoio conceitual específico do paradigma das ciências biológicas como a seleção natural, validando as conclusões a partir do uso de dadosT de Toulmin da investigação realizada pelos alunos. / The scientific education has focused on pedagogical activities that use students investigative practice. One of the objectives is so that students not only obtain the scientific concepts, but also the specific practices of science activity. It is a pretention that students develop their scientific argumentation competence. This investigation aims at understanding how students develop their written argumentation, analyzing their use of data as evidence of natural selection in order to sustain their conclusions about biological evolution investigative questions. We made a didactic sequence, which architecture establishes the foundation to the teachers pedagogical actions, and promotes students investigative actions. The sequence lies on two integrative bases: a) an investigation based scientific education and b) Darwins investigation on the natural selection as a mechanism of the historical construction matrix of biological evolution. In order to examine how would it be the biological evolution teaching based in Darwins investigative structure, our problem question was built with two main focuses: a) how could we articulate conceptual and methodological intentions, characteristic to biological sciences, with the approach of the main historical obstacles of natural selection in evolving into the concept of the mechanism of biological evolution in a didactic sequence based upon inquiry and b) how it is the use of data as evidence of natural selection in the high school students written argumentative structure during the application of Inquiry Based Biology Teaching Sequence (SEEBI, in Portuguese) to biological evolution teaching. To investigate our task, we developed a SEEBI that was applied by a public networks teacher to 125 high schools senior year students in a public school of São Paulo. Our methodology has qualitative and quantitative approaches. Our data consists of: a) materials (textbooks, experimental models, audio-visual resources used in class) and b) booklets with answers written by the students after the proposed activities. The data analyses were based upon these booklets, with students written answers, materials elaborated and posted in the SEEBI and also in the transcription we did. The results show that SEEBI has its foundation lied on conceptual and methodological intentions, characteristic to Biology. Furthermore, the results indicate an overcoming of conceptual obstacles as well, such as cosmic teleology and fixism, therefore, building the concept of natural selection as a mechanism of biological evolution. The study of the consequences presents an improvement in students argumentative ability, a strong correlation between the use of data from biological evolution with the construction of higher quality arguments by the students, using justifications (warranty and theoretical support) grounded in scientific knowledge. Theres evidence of an expansion of the arguments construction, both increasing the number of used components as well as the field-dependent components of sciences quality, such as support and evidence. The arguments constructed shall provide support based on specific conceptual assistance in paradigms of Biology, like natural selection, validating the findings from the use of data (Toulmin, 2006) in researches conducted by students.

A construção de inscrições e seu uso no processo argumentativo em uma atividade investigativa de biologia / The construction of literary inscriptions and their use in the argumentative process in an inquiry-based learning activity in biology

Silva, Maíra Batistoni e 13 March 2015 (has links)
Nos últimos anos aumentou o número de pesquisas que abordam aspectos epistemológicos no ensino de ciências, destacando a ideia de que este não deve se preocupar somente com a aquisição de conceitos, mas também deve possibilitar que os alunos se apropriem das práticas epistêmicas da ciência, favorecendo assim a Alfabetização Científica. As páginas que se seguem apresentam um estudo de caso qualitativo planejado e realizado para compreender como se dá o engajamento dos alunos em práticas epistêmicas da cultura científica. Nosso principal objetivo foi analisar as práticas de inscrição realizadas pelos alunos e suas relações com a produção de explicações e argumentos durante uma atividade investigativa sobre crescimento populacional de Lemna sp. Os dados da pesquisa foram coletados durante as aulas de biologia em duas classes do primeiro ano do ensino médio (alunos com idades entre 15 e 16 anos) de uma escola pública estadual da cidade de São Paulo. A análise da sequência didática e dos relatórios produzidos pelos alunos nos forneceu evidências de que as práticas epistêmicas experimentadas pelos alunos ao longo da atividade de investigação diferem a depender do tipo de dado coletado por eles, se de acordo com o modelo explicativo já conhecido ou diferente do previsto pelo modelo. Além disso, nossa análise evidenciou que o contexto de investigação constitui-se como importante repertório interpretativo das inscrições literárias produzidas pelos alunos, favorecendo a construção de explicações com garantia nos dados coletados. O contexto de investigação também se mostrou relevante na construção de argumentos, uma vez que a maioria das justificativas utilizadas era de natureza empírica, especialmente nos relatórios dos alunos que trabalharam com dados não previstos pelo modelo explicativo. Assim, após análise da sequência didática e dos relatórios produzidos pelos alunos, encontramos evidências de que a atividade de investigação propiciou oportunidades de engajamento em práticas epistêmicas da cultura científica, especialmente aquelas relacionadas à produção e intrepretação de inscrições literárias, o que favoreceu o processo de construção de explicações e argumentos, práticas fundamentais na produção do conhecimento científico. / In recent years increased the number of researches on epistemological aspects in science teaching, emphasizing the idea that this shouldn\'t be concerned only with the acquisition of concepts, but should also enable students to take ownership of epistemic practices of science, favoring so the Scientific Literacy. Here, is presented a qualitative case study planned and conducted to understand how is the engagement of students in epistemic practices of scientific culture. Our aim was to analyze the application of practices carried out by students and their relationship with the production of explanations and arguments during an investigative activity on growth of Lemna sp population. The data were collected during biology classes from high school classes in a public high school, São Paulo city, Brazil (students aged: 15 to 16 years). The analysis of the inquiry-based learning activity and reports produced by the students provided us with evidence that the epistemic practices experienced by the students during the research activity differ depending on the data type collected by them, in accordance with the explanatory model already known by students or different predicted by these model. In addition, our analysis showed that the research context constitutes an important interpretive repertoire of literary inscriptions produced by the students, favoring the construction of explanations to assure the data collected. The research context was also relevant in the construction of arguments, since most of the justifications used was empirical, especially, in the reports of the students who worked with data not provided by the explanatory model. So after a review of inquiry-based learning activity and reports produced by the students, we found evidence that this inquiry-based learning activity led engagement opportunities in epistemic practices of scientific culture, especially those related to production and interpretation of literary inscriptions, which favored the process of construction of explanations and arguments, fundamental issues for the production of scientific knowledge.

The effects of reciprocal teaching on the science literacy of intermediate elementary students in inclusive science classes

Unknown Date (has links)
Intermediate elementary students (grades 4 and 5) frequently struggle to become scientifically literate in their general education classrooms. Scientific literacy includes knowing how to access and use information found in science texts. Unfortunately, many students struggle to read and understand science texts (Michalsky, Mevarech, & Haibi, 2009, p. 363). Fortunately, elementary students have shown improvement in reading comprehension when explicitly instructed in cognitive and metacognitive strategies to comprehend expository text in settings that support collaboration and flexible application of comprehension strategies, and have meaningful opportunities for reading and writing (Mastropieri & Scruggs, 2004; Palincsar & Klenk, 1992). A method that includes these components is reciprocal teaching (RT; National Reading Panel, 2000). RT has been used during content area instruction to increase reading comprehension skills of intermediate elementary students without disabilities in general education classrooms (King & Johnson, 1999; Lederer, 2000; Lubliner, 2004). These reading comprehension gains have been maintained by students on follow-up tests after the RT intervention has been withdrawn (Palincsar & Brown, 1984; Westera & Moore, 1995). This study examined the effects of RT on the science literacy of intermediate elementary students (grades 4-5) participating in inclusive science classes. Students with learning disabilities (SWLD), students at-risk (AR), and students in general education (GE) participated in this study. General education teachers used RT with science texts to improve science literacy. Pre/post science quizzes were used to assess the effects of the RT intervention, and post/follow-up tests assessed potential maintenance of the RT. s / Analyses of the data showed that the RT intervention resulted in improved science comprehension overall, and for each student group. In addition, the results showed that the gains were maintained for the individual student grouping after the RT intervention was removed, although these gains were not found overall.The study demonstrated that the use of RT during science instruction in inclusive, intermediate elementary classes assisted students who are AR, SWLD, and students in GE to attain science knowledge using standard science texts and materials. These results extend the experimental literature on science literacy and reciprocal teaching, particularly among intermediate elementary students. / by Kim E.

Proposta de projeto integrador para o desenvolvimento das habilidades e competências empreendedoras no ensino médio técnico integrado em uma escola agrícola federal /

Alvarenga, Paulo Sérgio Romeu. January 2018 (has links)
Orientador: José de Souza Rodrigues / Coorientadora: Arminda Eugenia Marques Campos / Banca: Renato de Campos / Banca: Marco Antonio Carvalho Pereira / Resumo: O ensino empreendedor pode melhorar diversos aspectos comportamentais dos alunos, como incentivá-los a criar o próprio emprego. O desenvolvimento de projetos pode estimular a evolução de diversas habilidades e competências empreendedoras esperadas em alunos de cursos técnicos. Observadas as duas premissas, este estudo propôs o uso de projeto integrador como estratégia para desenvolver o ensino empreendedor entre alunos de uma escola agrícola federal. O estudo baseou-se na análise documental da proposta pedagógica do curso técnico em agroindústria integrado ao ensino médio e em modelos que envolvem educação empreendedora e aprendizagem baseada em projetos. A proposta é, também, uma resposta a alguns desafios encontrados, tais como a necessidade de permanência dos alunos na escola sem atividades programadas e a superação de limitações impostas pelo desenvolvimento de projetos em disciplinas isoladas, algo que é semelhante, em termos de prática pedagógica, ao modelo tradicional de ensino. A proposta final foi elaborada a partir da adaptação de modelos educacionais e contribuições dos professores, porém precisa passar por uma avaliação mais profunda em termos dos custos envolvidos. Os resultados indicam que apesar da atual proposta pedagógica apresentar eixos teóricos e práticos voltados ao desenvolvimento de atividades interdisciplinares, estas permanecem sem conexão em nível subjetivo aos métodos de ensino de cada professor. Os resultados também indicam que a melhor forma de de...

The development of projects can stimulate the evolution of several skills and entrepreneurial skills expected in students of technical courses. Based on the two premises, this study proposed the use of an integrative project as a strategy to develop entrepreneurial education among students of a federal agricultural school. The study was based on the documentary analysis of the pedagogical proposal of the technical course in agroindustry integrated to high school and in models that involves entrepreneurial education and project-based learning. The proposal is also a response to some of these challenges, such as the need for students to stay in school without programmed activities and to overcome the limitations imposed by the development of projects in isolated disciplines, something that is similar in terms of pedagogical practice, to the traditional model of education. The final proposal was drawn from the adaptation of educational models and teachers' contributions, but it needs to take more profound evaluation in terms of the costs involved. The results indicate that in spite of the current pedagogical proposal, theoretical and practical axes focused on the development of interdisciplinary activities remain isolated at a subjective level to the teaching methods of each teacher. The results also indicate that the best way to develop the entrepreneu... (Complete abstract click electronic access below) / Mestre
