Assessment in the science classroom

This paper reports on research into two teachers' views and practices about assessment at the classroom level. Emphasis was given to practical work and its assessment. Findings suggest it is unhelpful to define practical work as distinct from other activities in the science classroom. Various methods used for assessing activity within the participant teachers' classrooms are described. The participant teachers were found to be primarily concerned about issues of ‘fairness’: task validity, reliability of assessment based on co-operative work and assessment of the affective domain. The place of teacher intuition in assessment is raised and briefly discussed. Directions for the ongoing research are foreshadowed. Specializations: science education, technology education, assessment and curriculum development.     

A teacher's implementation of authentic assessment in an elementary science classroom

This study describes an elementary school teacher's implementation of authentic assessment strategies in her science classes. After completing a graduate elementary science methods course, this teacher decided to make changes that would align her assessment strategies with her hands-on approach to teaching science. She experimented with a variety of assessment strategies and was successful in the use of science logs, performance assessment, creative drama, scrapbooks, and interviews, while rejecting the use of portfolios. Factors that contributed to the successful implementation included administrative support, close contact with parents, collaboration with university faculty, teacher's ownership, and the teacher's flexibility to try a variety of strategies. The teacher's perception of assessment shifted toward an integrated model wherein instruction and assessment occur simultaneously. Her typical reaction after assessing her students changed from disappointment in how they performed on a test to surprise at how much they knew. © 1996 John Wiley & Sons, Inc.

Rethinking the classroom science investigation

There is now a significant research literature devoted to reconceptualizing scientific activities, such as modeling, explanation, and argumentation, to realize a vision of science-as-practice in classrooms. As yet, however, not all scientific practices have received equal attention. Planning and Carrying out Investigations is one of the eight scientific practices identified in the Next Generation Science Standards, and there is a long line of research from both psychological and science education traditions that addresses topics about investigation, such as the generation and interpretation of evidence. However, investigation has not been subject to concerted reconceptualization within recent research and instructional design efforts focused on science-as-practice. In this article, we propose a framework that centers the investigation as a key locus for constructing alignments among phenomena, data, and explanatory models and makes visible the work that scientists engage in as they develop and stabilize alignments. We argue that these alignments are currently under-theorized and under-utilized in instructional environments. We explore four opportunities that we argue are both accessible to students from a young age and can support conceptual innovation. These are (a) developing empirical systems, (b) getting a grip on empirical systems, (c) determining, defining and operationalizing data as “evidence,” and (d) making sense of what the results of empirical systems do and do not help us understand.     

Computer technology-cognitive psychology interface and science performance assessment

The emerging interface between computer technology and cognitive psychology for performance assessment in science education is explored. Cognitive theories of learning offer promises to transform computer technology from a test administration tool into a process assessment tool, and computer technology offers a medium for studying the cognitive processes of learning. Interface theories and interface technologies are briefly discussed. The technology-psychology interface may be a base for building an alternative assessment technology. Some prototype projects in this line of inquiry are presented. As in any other novel approaches to testing, there are several questions that need to be answered in establishing the role of the technology-psychology interface in performance assessment.     

Learning science through talking science in elementary classroom

Elementary students in grade two make sense of science ideas and knowledge through their contextual experiences. Mattis Lundin and Britt Jakobson find in their research that early grade students have sophisticated understandings of human anatomy and physiology. In order to understand what students’ know about human body and various systems, both drawings and spoken responses provide rich evidence of their understanding of the connections between science drawings and verbal explanations. In this forum contribution, we present several theoretical connections between everyday language and science communication and argue that building communication skills in science are essential. We also discuss how young participants should be valued and supported in research. Finally we discuss the need for multimodal research methods when the research participants are young.     

Children linking science and technology in the primary classroom

This research project exemplifies how technology can facilitate scientific investigations. It also highlights how enthusiastic children can be when they are encouraged to pose their own questions and take responsibility for finding the answers. Year 5 children, working in groups, were involved in designing, making and appraising catchers and enclosures used to investigate small animals found within their school's grounds. A videotape of this project was made and should be a valuable resource for the professional development of both trainee and practising teachers. Included in the tape are children's spontaneous comments, their concern for animal welfare, and reflection on the various aspects of their investigations. Syndal South Primary School     

Active classroom participation in a Group Scribbles primary science classroom

A key stimulus of learning efficacy for students in the classroom is active participation and engagement in the learning process. This study examines the nature of teacher–student and student–student discourse when leveraged by an interactive technology—Group Scribbles (GS) in a Primary 5 Science classroom in Singapore which supports rapid collaborative knowledge building (RCKB). We envisaged nine design principles for RCKB in the design of lessons and postulated a logic model that links and explains the effects of our design principles to the ultimate goal of learning efficacy. We presented a case study of a GS lesson which shows that GS affordances leveraged by good lesson and activity design could enable the students to have more epistemic agency. Students had opportunities to participate spontaneously in class discussions by fully expressing their ideas without inhibition. The technology effect is used to support instant formative feedback and interactions among students effectively.     

A sense of place in the science classroom

Place‐based science education engages with the laboratories of complex reality where natural processes combine with social practice, going beyond the physical world, to encompass the meanings and sense of attachment local residents feel for places. This brief report describes how a university science methods class in a primary teacher training programme situated scientific understandings in the rich cultural context of the historically rural and socio‐economically disadvantaged area of Galicia in north‐western Spain, where agrarian traditions continue to influence local culture. Focusing on student responses to two assignments, this brief report explores how the preparation of lesson plans related to food and environmental investigation projects served to integrate aspects of the natural, social and cultural environment to foster a critical pedagogy of place.     

Children's environmental identity and the elementary science classroom

This qualitative research explores children's environmental identity by describing how fifth grade children view their relationship with the natural world alongside their experience of elementary school science. Qualitative analysis of in-depth interviews with 17 grade 5 children was supported with a survey that included responses to open-ended survey items. Analyses convey that children recognize and describe their own environmental identity, but that identity is often unacknowledged in the science classroom. This lack of acknowledgment may limit connections of school science to children's interests and emotional attachment to the natural world.
