Effects of active‐learning experiences on achievement, attitudes, and behaviors in high school biology

Abstract

Active-learning labs for two topics in high school biology were developed through the collaboration of high school teachers and university faculty and staff and were administered to 408 high school students in six classrooms. The content of instruction and testing was guided by State of Texas science objectives. Detailed teacher records describing daily classroom activities were used to operationalize two types of instruction: active learning, which used the labs; and traditional, which used the teaching resources ordinarily available to the teacher. Teacher records indicated that they used less independent work and fewer worksheets, and more collaborative and lab-based activities, with active-learning labs compared to traditional instruction. Inclass test data show that students gained significantly more content knowledge and knowledge of process skills using the labs compared to traditional instruction. Questionnaire data revealed that students perceived greater learning gains after completing the labs compared to covering the same content through traditional methods. An independent questionnaire administered to a larger sample of teachers who used the lab-based curriculum indicated that they perceived changing their behaviors as intended by the student-centered principles of the labs. The major implication of this study is that active-learning-based laboratory units designed and developed collaboratively by high school teachers and university faculty, and then used by high school teachers in their classrooms, can lead to increased use of student-centered instructional practices as well as enhanced content knowledge and process learning for students. ß 2007 Wiley Periodicals, Inc.

Effectiveness of an inquiry-based learning using interactive simulations for enhancing students’ conceptual understanding in physics

“…Previous studies have indicated that inquiry-based instruction increases students' argumentation skills (Baron, 1991;Driver et al, 2000;Taraban et al, 2007;Tsai, 2001). This study further found that using scientific discourse in presentation provides opportunities to develop students' scientific communication skills.…”

Percepção dos alunos acerca das estratégias de promoção do sucesso educativo e envolvimento com a escola

“…O International Congress of School Improvement and School Efficacy é um exemplo de um organismo internacional de promoção da eficácia educativa, pela via da promoção de estratégias nesse sentido. Na organização escolar, existem evidências de que a promoção de determinadas dimensões tem um impacto significativo positivo nas trajetórias acadêmicas dos alunos (Epstein & Sheldon, 2002;Lee & Burkam, 2003), principalmente quanto a: (a) plasticidade do sistema escolar: capacidade da escola e do contexto educativo de se adaptar às características e necessidades dos alunos (Bryk, Easton, Kerbeow, Rollow, & Sebring, 1994;Reynolds, A. Harris, Clarke, Harris, & James, 2006;Taylor & Adelman, 1999); (b) monitorização constante (Gullatt & Lemoine, 1997;Taylor & Adelman, 1999;Wagstaff, Combs, & Jarvis, 2000); (c) existência de atividades extracurriculares (DeKalb, 1999;Feldman & Matjasko, 2005;Gilman, Meyers, & Perez, 2004); (d) tutoria: desenvolvida por professores ou colegas mais velhos que apoiam os alunos com maiores dificuldades (Gonzales, Richards, & Seeley, 2002;Tierney, Grossman, & Resch, 1995); (e) promoção de atividades de aprendizagem ativa: os alunos realizam suas tarefas de modo autônomo e com os seus pares (Bell & Kozlowski, 2008;Taraban, Box, Myers, Pollard, & Bowen, 2007;Yoder & Hochevar, 2005); (f) aprendizagem individualizada: os professores adaptam suas práticas de ensino a cada aluno (Adelman & Taylor, 1993;W. Stainback & Stainback, 1992;Switzer, 2004); (g) utilização de tecnologias educativas, em casa e na escola (Hartley, 2007;Imel, 1999;Wesley, 2004); e (h) educação para a carreira (Stone, 2004;Stone & Aliaga, 2002).…”

The incorporation of the USA 'Science Made Sensible' programme in South African primary schools: A cross-cultural approach to science education

“…Constructivism-based instructional materials are commonly classified under the name of 'inquiry-based' and include hands-on activities as a way to inspire and engage learners while concretizing science concepts (Minner, Levy & Century 2009). Hands-on learning activities are consistent with learner-centred strategies based on a constructivist learning-teaching approach (Taraban, Box, Myers, Pollard & Bowen 2007). Inquiry-based learning refers to the pedagogical approach that uses the general processes of scientific inquiry as its teaching and learning methodology (Ketpichainarong, Panijpan & Ruenwongsa 2010).…”
