Challenge in learning and teaching science

Taking as a basis a conceptualisation of personal challenge having both cognitive/metacognitive (thinking) and affective (feeling) components, the nature and extent of perceived challenge in learning and teaching science were explored for seven teachers and thirty-seven students in five secondary schools over a period of five months. Findings suggest that many secondary students are not challenged by the science they learn in school. Similary, many secondary science teachers are insufficiently challenged by the task of teaching. There are indications, however, that science teaching and learning attitudes and practices can be improved if teachers work to diagnose and change key classroom factors that influence level of perceived challenge in learning.     

Peer teaching and higher level cognitive learning outcomes in problem-based learning

Law education at the University of Limburg (Maastricht, The Netherlands) features small-group tutorials alternating with periods of independent study. Every group of 10 students was tutored by a staff member or an undergraduate student from the third or fourth year. Students guided by a staff member scored significantly higher on a test designed to measure higher order cognitive skills than students guided by a student tutor. Student tutors were rated no differently from staff tutors with respect to the way they stimulated learning processes, directed the discussion content and monitored the discussion process. It seems that in a quantitative way, staff tutors and student tutors behave more or less the same. Qualitatively, however, there may be differences in their behavior which the tutor functioning questionnaire is unable to tap. Interventions of staff tutors may be more to the point than those of student tutors due to the fact that they are experts in their fields.     

Model-based teaching and learning about inheritance in third-grade science

ABSTRACT

Research suggests that it is challenging for elementary students to develop conceptual understanding of trait variation, inheritance of traits, and life cycles. In this study, we report on an effort to promote elementary students’ learning of hereditary-related concepts through scientific modelling, which affords opportunities for elementary students to generate visual representations of structure and function associated with heredity. This study is part of a four-year design-based research project aimed at supporting students’ learning about life science concepts using corn as a model organism. Study data were collected during the implementation of a project-developed, multi-week, model-based curriculum module in eight third-grade classrooms located in the Midwestern United States. Through mixed methods research, we analysed video recorded observations of curriculum implementation, student artefacts, and student interviews. Results illustrate epistemic dimensions of model-based explanations (MBEs) for heredity that students prioritised, as well as significant variation in students’ MBEs in 2 of the 8 classrooms. While findings show neither students’ content knowledge nor model-based instruction associated with their MBEs, qualitative differences in teachers’ curriculum enactment, and more general approaches to science instruction, may help explain observed differences. Implications are discussed for curriculum and instruction in support of students’ MBE for heredity-related concepts.

Mobile phone images and video in science teaching and learning

This article reports a study into how mobile phones could be used to enhance teaching and learning in secondary school science. It describes four lessons devised by groups of Sri Lankan teachers all of which centred on the use of the mobile phone cameras rather than their communication functions. A qualitative methodological approach was used to analyse data collected from the teachers' planning, observations of the lessons and subsequent interviews with selected pupils. The results show that using images and video captured on mobile phones supported the teachers not only in bringing the outside world into the classroom but also in delivering instructions, in assessing students' learning and in correcting students' misconceptions. In these instances, the way the images from the mobile phone cameras supported students' learning is explained using a variety of approaches to understand how images support learning.     

The importance of reflection in improving science teaching and learning

The purpose of this three-year naturalistic case study was to see whether collaborative reflection could enhance teaching and learning of science by generating desirable cognitive, metacognitive, and affective outcomes. Reflection was both individual and in groups, and involved reflection on practice in the classroom and phenomenological reflection on the nature of science teaching and learning. The study had two components. The preservice component involved 13 student teachers and teacher educators. The in-service component involved 14 novice and experienced science teachers and 350 of their students. The authors worked with both groups to devise ways of changing classroom attitudes and behaviors of teachers and students. The voluminous data collected include records of many interviews, questionnaires, and written evaluations. Findings from the study illuminate aspects of the nature of science teaching and learning, processes by which individuals improve the quality of their practice, and methods for exploring teaching and learning mechanisms and facilitating change. Central to these findings is the importance of each of the two types of reflection for fostering personal and professional development. For both teachers and students, both types of reflection acted to improve their knowledge, awareness, and control of themselves and their classroom practice.     

Teacher beliefs about learning and teaching in primary science and technology

It is argued that the introduction of many new curricular with their associated teaching practices have failed because the beliefs, views and attitudes of teachers have been ignored. This paper reports the implications of the initial belicfs of primary school teachers involved in a professional development program about science and technology education. In particular, a mismatch between teachers views of learning and teaching is identified and analysed.

Researching balance between cognition and affect in science teaching and learning

This paper is based on findings from a three year collaborative action research project on classroom teaching and learning. The research, which involved 33 teachers, over two thousand students from six schools, and the authors, centred on exploring how various features of the classroom context influence teaching and learning processes. We interpret project findings as indicating the importance of balance between cognition and affect for effective teaching and learning. We advance the notion of challenge as a way of conceptualising this balance. Challenge comprises a cognitive/metacognitivedemand component and an affectiveinterest component. Nine major features of a teaching/learning event were found to interact to influence these cognitive and affective components of challenge. Specializations: Collaborative research on science teaching and learning; staff development and school improvement; quality of science education. Specializations: Learning and teaching science; pre-service teacher education. Specializations: teacher development in science education; technology education. Specializations: Science and teachnology curriculum, environmental education, educational disadvantage. Specializations: learning theory, probing of understanding, conceptual change.     

Innovating science teaching with a transformative learning model

Abstract

This exploratory study aimed to describe the impact of the ‘Science in Family project’, as a transformative learning model for science teachers trying to improve student’s attitudes toward STEM subjects. This study took place in a public elementary school in Monterrey, Mexico, which has been developing this project for more than thirteen years with students from 4th, 5th and 6th grade. We used participant observation and interviews with four families whose children are students of this elementary school, and with one family whose sons were students of this school some years ago. Results showed that there is a relationship between positive attitudes towards science in students who were exposed to transformative learning models of teaching. Two of the participants took steps to follow science related careers. This study helps to illuminate the extent to which teacher education models influence students’ attitudes and how positive attitudes to science are influenced by the use of learning by doing projects.     

Remedial classroom teaching and computer-assisted learning with science students in Botswana

The mathematical background of new science students in Botswana and the effectiveness of teaching is investigated through a series of test instruments. It is found that many mathematical concepts and techniques, theoretically covered in the school curriculum, are not well established. Further research shows that teaching remedial mathematics in class improves student results, but also that several misconceptions remain. Material for computer-assisted learning, specifically developed to promote conceptual change is shown to have a positive effect. Research data are analysed for different student ability groups.     

A constructivist approach to change in elementary science teaching and learning

Constructivism is a set of beliefs that can be used by teachers to think about learning and teaching and to plan and enact a science curriculum. This paper is a fictional account of an elementary science teacher and her use of constructivism as a referent for her various roles as a science teacher. The paper also describes how the teacher came to teach in this manner, describing her involvement in staff development activities and an evolution in her thinking from an ojectivist to a constructivist system of semantics. Implications are presented for the reform of science education.     

State-mandated accountability as a constraint on teaching and learning science

The purpose of this study is to examine the effect of state-mandated policy, emphasizing control through performance-based instruction and student test scores as the basis for determining school accreditation, on the teaching and learning of science. The intended consequence of instigating the rational theory of management by one state is to improve their current level of student literacy. However, some contend that the implementation of the policy has results that are not intended. The identification of the tension between the intended and unintended results of centralized policy making is the basis for examining a specific case in which the rational model is implemented. One hundred and sixty-five seventh-grade science students and four teachers are participants in the study. Qualitative analysis is the research methodology used as a means to provide detailed information about the contextual nature of the classroom processes. The intention is to identify and describe features of the behavior setting that influence the behavior of the teachers and their students. Three assertions generated during the field work were: Teachers redefine the goals of science instruction as the acquisition of facts and isolated skills, teachers alter their usual instructional behavior to implement uniform instructional procedures, and the teacher/student classroom interaction constrains students' opportunities to learn science. The implications of the study indicate that the state-mandated policy has results that are in opposition to the intended results. Instead of improving the practices of teachers, the implementation of the policy constrains and routinizes the teachers' behavior, causing them to violate their own standards of good teaching. They feel pressured to “get through” the materials so students will score well on tests. The classroom interaction is structured in such a way as to inhibit students from asking questions of their own. As a result, students' opportunity to express curiosity and inquiry—central processes in scientific thinking—are constrained. These unintended consequences of the implemented state policy, instead of improving science teaching and learning, continue to reduce science instruction to the literal comprehension of isolated facts and skills.
