The pedagogy of argumentation in science education: science teachers’ instructional practices

ABSTRACT

Argumentation has been a prominent concern in science education research and a common goal in science curriculum in many countries over the past decade. With reference to this goal, policy documents burden responsibilities on science teachers, such as involving students in dialogues and being guides in students’ spoken or written argumentation. Consequently, teachers’ pedagogical practices regarding argumentation gain importance due to their impact on how they incorporate this practice into their classrooms. In this study, therefore, we investigated the instructional strategies adopted by science teachers for their argumentation-based science teaching. Participants were one elementary science teacher, two chemistry teachers, and four graduate students, who have a background in science education. The study took place during a graduate course, which was aimed at developing science teachers’ theory and pedagogy of argumentation. Data sources included the participants’ video-recorded classroom practices, audio-recorded reflections, post-interviews, and participants’ written materials. The findings revealed three typologies of instructional strategies towards argumentation. They are named as Basic Instructional Strategies for Argumentation, Meta-level Instructional ?St??rategies for ?Argumentation, and Meta-strategic Instructional ?St??rategies for ?Argumentation. In conclusion, the study provided a detailed coding framework for the exploration of science teachers’ instructional practices while they are implementing argumentation-based lessons.     

Validation of Automated Scoring for a Formative Assessment that Employs Scientific Argumentation

Scientific argumentation is one of the core practices for teachers to implement in science classrooms. We developed a computer-based formative assessment to support students’ construction and revision of scientific arguments. The assessment is built upon automated scoring of students’ arguments and provides feedback to students and teachers. Preliminary validity evidence was collected in this study to support the use of automated scoring in this formative assessment. The results showed satisfactory psychometric properties related to this formative assessment. The automated scores showed satisfactory agreement with human scores, but small discrepancies still existed. Automated scores and feedback encouraged students to revise their answers. Students’ scientific argumentation skills improved during the revision process. These findings provided preliminary evident to support the use of automated scoring in the formative assessment to diagnose and enhance students’ argumentation skills in the context of climate change in secondary school science classrooms.     

Science and Language Teachers’ Assessment of Upper Secondary Students’ Socioscientific Argumentation

Researchers and policy-makers have recognized the importance of including and promoting socioscientific argumentation in science education worldwide. The Swedish curriculum focuses more than ever on socioscientific issues (SSI) as well. However, teaching socioscientific argumentation is not an easy task for science teachers and one of the more distinguished difficulties is the assessment of students’ performance. In this study, we investigate and compare how science and Swedish language teachers, participating in an SSI-driven project, assessed students’ written argumentation about global warming. Swedish language teachers have a long history of teaching and assessing argumentation and therefore it was of interest to identify possible gaps between the two groups of teachers’ assessment practices. The results showed that the science teachers focused on students’ content knowledge within their subjects, whereas the Swedish language teachers included students’ abilities to select and use content knowledge from reliable reference resources, the structure of the argumentation and the form of language used. Since the Swedish language teachers’ assessment correlated more with previous research about quality in socioscientific argumentation, we suggest that a closer co-operation between the two groups could be beneficial in terms of enhancing the quality of assessment. Moreover, SSI teaching and learning as well as assessment of socioscientific argumentation ought to be included in teacher training programs for both pre- and in-service science teachers.     

Students' Argumentative Writing Skills in Science and First-Language Education: Commonalities and differences

The ability to build arguments is a crucial skill and a central educational goal in all school subjects including science as it enables students to formulate reasoned opinions and thus to cope with the increasing complexity of knowledge. In the present cross-sectional study, we examined the domain-specificity of argumentative writing in science by comparing it with a rather general type of argumentation as promoted in first-language education and with formal reasoning to gain insight into different forms of argumentation on theoretical and empirical levels. Using a paper-and-pencil test, we analyzed written argumentations and the reasoning abilities of 3,274 Grade-10 students in German secondary schools. Correlation and multiple regression analyses as well as a qualitative analysis of students' answers to a subset of tasks in the domains of science and first-language education were conducted. Results showed moderate relations between argumentation in science, argumentation in first-language education, and reasoning. Half of the variance in argumentation in science was explained by individual differences in argumentation in first-language education and reasoning. Furthermore, the examination of written arguments revealed differences, for example, in students' weighing of pros and cons. We assume that the familiarity of the underlying scientific information may play an essential role in the argumentation process and posit that it needs to be investigated in more detail. Overall, the study indicates that investigating the argumentational abilities of learners in first-language education and reasoning abilities can help to shed light on the domain-specificity of argumentation in science.     

Thinking beyond the score: Multidimensional analysis of student performance to inform the next generation of science assessments

Conventional assessment analysis of student results, referred to as rubric-based assessments (RBA), has emphasized numeric scores as the primary way of communicating information to teachers about their students’ learning. In this light, rethinking and reflecting on not only how scores are generated but also what analyses are done with them to inform classroom practices is of utmost importance. Informed by Systemic Functional Linguistics and Latent Dirichlet Allocation analyses, this study utilizes an innovative bilingual (Spanish–English) constructed response assessment of science and language practices for middle and high school students to perform a multilayered analysis of student responses. We explore multiple ways of looking at students’ performance through their written assessments and discuss features of student responses that are made visible through these analyses. Findings from this study suggest that science educators would benefit from a multidimensional model which deploys complementary ways in which we can interpret student performance. This understanding leads us to think that researchers and developers in the field of assessment need to promote approaches that analyze student science performance as a multilayered phenomenon.     

Student perspectives on formative feedback as part of writing portfolios

Despite the crucial role that students play in formative assessment practices, student perspectives on such practices are relatively under-researched. Through a qualitative analysis of 128 reflection notes written by student teachers of English, this article investigates the students’ perceptions of formative feedback as part of portfolio assessment at two teacher education institutions in Norway. As such, it contributes to bridging the gap between research and practice. Students received peer and teacher feedback on assignments and wrote reflection notes during the semester. Findings show that students are positive towards teacher feedback and highlight the significance of teacher praise. Main objections raised against peer feedback concern the lack of constructive criticism. However, positive attitudes towards peer discussion groups suggest that they may be a more effective way of implementing peer assessment than formalised written peer commentary. Student reflections suggest that a failure to understand the task and the feedback is a possible hindrance to successfully revising assignments. Overall, students’ positive attitudes towards the portfolio process, which includes multiple drafting, suggest that students in higher education would benefit from more opportunities to revise and resubmit their work, yet they need adequate practice in providing peer feedback, and interpreting and implementing feedback in general.     

Implementing curriculum-embedded formative assessment in primary school science classrooms

The implementation of formative assessment strategies is challenging for teachers. We evaluated teachers’ implementation fidelity of a curriculum-embedded formative assessment programme for primary school science education, investigating both material-supported, direct application and subsequent transfer. Furthermore, the relationship between implementation fidelity and teacher variables was explored. N = 17 German primary school teachers participated in professional development on formative assessment, N = 11 teachers formed a control group. Teachers’ implementation fidelity was evaluated via classroom observations student ratings and an analysis of students’ workbooks, focusing on the frequency and quality of intended formative assessment elements (assessments, feedback and instructional adaptations). Regarding direct application, treatment group teachers’ implementation fidelity was high, with slight variations in quality. Regarding transfer, implementation fidelity was lower but teachers still implemented more formative assessment elements than the control group. Teachers’ pedagogical content knowledge and their evaluation of the formative assessment intervention were associated with implementation success.     

The exclusive language of science? Comparing knowledge gains and motivation in English-bilingual biology lessons between non-selected and preselected classes

The dominant role of English as the global language of science entails a requirement for science teachers to equip their non-native English-speaking students with receptive and productive language skills for communication in scientific contexts. Although science courses with English elements are part of some schools’ bilingual programmes, they are usually not available to a wider student audience, but are restricted to high achieving or highly motivated students. The present study was to test whether a newly developed biology content and language integrated learning (CLIL) unit could also benefit standard ninth grade classes. The learning gains and motivation of bilingually inexperienced students were compared to those of a preselected group and a comparison group that had been taught solely in their native language. All participating classes achieved similar gains in content knowledge, and the standard students rated their motivation for bilingual science lessons as positive, albeit not as high as the preselected group. We thus provide evidence against concerns that teaching non-selected students bilingually might lead to deficits in content knowledge acquisition. Following this, we conclude that scientific English should be a part of standard science lessons regardless of specific school programmes.     

Powerful words: skillful and sensitive empowerment of urban undergraduate pre‐service teachers through improvement of Standard English usage

With the goal of assisting predominantly low‐socio‐economic status and minority undergraduate education majors to achieve necessary competence in the use of oral and written Standard English, an innovative action research initiative was incorporated into an introductory education class at a comprehensive urban university in the northeastern part of the United States. The project integrated written and oral Standard English exercises into the course’s curriculum as a means of bolstering students’ skills while still helping them master the course content. Preliminary results demonstrate students’ improved competence in both written and oral Standard English, and an increased awareness of how and when to use various forms of English.     

Making learning effective – quantity and quality of pre-service teachers’ feedback

ABSTRACT

Feedback is an essential formative assessment practice that has the potential to influence student learning and achievement positively. Providing effective feedback, however, is a challenging task for teachers. Especially beginning teachers struggle with the provision of information that supports students in developing and improving their competences. Learning to provide feedback thus is an important aspect of teacher education. The present exploratory study investigates pre-service chemistry teachers’ practices regarding the judgement of students’ level of achievement and the provision of feedback in the context of the control-of-variables strategy. A sample of N?=?40 bachelor and master students at Kiel University judged students’ written artefacts and provided feedback with the aim to support students in their progression towards the learning goals. The quality of the feedback was coded with respect to its correct judgement of the students’ current levels of achievement and the support it provided regarding next steps in learning. The results show that only a few of the pre-service teachers could correctly judge students’ current levels of achievement and provide feedback that is expected to be effective. Overall, the findings indicate a need for more research in this field and a need for the implementation of formative assessment practices as a topic in pre-service teacher education.     

A Remotely Operated Science Experiment framework for under-resourced schools

Teaching argumentation with appropriate activities and strategies would support a wide range of goals in science education. Though science labs have been suggested and employed for argumentation activities, such educational expenditures are likely to be beyond the means of most schools in under-resourced areas. Due to the lack of appropriate technological infrastructure and financial support, science education in developing countries is limited to the traditional approach. Teachers and students in the developing world, or other rural areas without sufficient lab resources in developed countries, would adopt argumentation in science classroom if they utilize their wireless infrastructure. We suggest a remote science lab for students in under-resourced schools, and suggest a possible way to engage them in argumentation activities. This paper introduces Remotely Operated Science Experiment (ROSE) and its implementation, and draws on the result of the intervention focusing on the impact of ROSE on students’ argumentation and learning.     

Testing and ideology: policy debates about literacy assessments for Colorado’s bilingual students

ABSTRACT

The Colorado Reading to Ensure Academic Development Act requires grade-level attainment in literacy in English for students in grades K-3. Its practical outcome, however, has been to pressure schools with bilingual programs to shift their instructional language allocations towards more English in the early grades. Proposed rule revisions debated by the state Board of Education sought to facilitate testing in students’ language of instruction for those in bilingual programs. Analysis of written and verbal opposition to the proposed rule revisions demonstrates the persistence of insidious ethnoculturalist discourses opposing bilingual education as well as the cooptation of liberal multiculturalist discourses that, while framing bilingualism as an asset, argue that it is underdeveloped in bilingual programs that do not include English instruction from the outset. Given that bilingual instruction has demonstrated time and again that it benefits students acquiring English in schools, such new discursive turns pose a threat that must be recognized to fend off further legislative and regulatory attempts against bilingual education.     

The impact of formative and shared or co-assessment on the acquisition of transversal competences in higher education

The use of formative and shared or co-assessment has been shown to improve the motivation, involvement and learning of university students. The aim of this study is to analyse the effect that implementing these processes has on university students’ perception of their acquisition of transversal competences. The participants in the study were 1021 students from five Spanish universities taking degree courses in primary education or physical education and sport science. They all experienced formative and shared or co-assessment throughout a complete academic year of their courses. For the data collection, a Self-Perception Scale of Transversal Competences was created, which had adequate values of reliability and validity. Using a transversal design (inter-subjects), inferential statistical analysis was undertaken of the differences in means between the perception of a range of transversal competences before and after the course. The results show significant perceived improvements at the end of the course for most of the competences analysed, which indicates, among other thing, the value and importance of this type of assessment for the educational process.     

Between two stories: assessment of and for learning

The study was conducted in a school for special education with small classes of six to 12 students. The aim was to illuminate how students’ understanding of written assessments could be related to assessment for learning. Twenty-nine students were asked to describe their understanding of written assessment in three different subjects and, further, to describe their perceptions in follow-up interviews. The two-step analysis first focused on individual understanding. Thereafter Vygotsky’s zone of proximal development (ZPD) was used as analytical tool. In the first analysis three categories were identified. Students’ understandings were related to subject matter knowledge, generic skills and attitudes. The findings of the second analysis indicated that written assessment often lacked formative features and cannot be seen as learning in the ZPD. Difficulties with schoolwork were seen as problems of the individual and the measures were directed towards the student. Even though the guidelines ask for a relational perspective a categorical perspective sometimes was adopted in the assessments. The implications of the study relate to the ways teacher’s assessment competences can encompass students’ understanding and how this can be translated into action.     

English-bilingual biology for standard classes development,implementation and evaluation of an English-bilingual teaching unit in standard German high school classes

English connects all areas of science around the world. Productive and receptive English-language skills are thus a crucial tool that schools must provide their students with in order to prepare them for higher education and professional life. The introduction of bilingual instruction of subject matter, often referred to as Content and Language Integrated Learning (CLIL), allows for incorporating English as a medium of communication directly into the science classroom. However, such bilingual lessons are often only accessible in the context of bilingual programmes for which students have to qualify based on their previous performance. The present study assessed the applicability of bilingual modules in non-selected groups of students. For this, a bilingual teaching unit on immunology was developed and implemented in standard German ninth grade classes. After the unit, bilingually taught students showed the same content knowledge gains as their peers who had been taught solely in their native language. Average achievement motivation ratings before and after the unit were medium to high in all classes, and the majority of students was open to more bilingual lessons. An evaluation of student comments provides further indications for the development of future bilingual units.     

Developing students' ability to engage critically with science in the news: identifying elements of the ‘media awareness’ dimension

Worldwide, science education reform movements are stressing the need to promote ‘scientific literacy’ among young people. Increasingly, this is taken to include empowering students to engage critically with science-related news reporting. Despite this requirement now featuring in statutory curricula throughout the UK, there has, to date, been a dearth of research-informed advice to assist science teachers as they identify appropriate instructional objectives in this regard and design relevant learning activities through which these might be achieved. In this study, prominent science communication scholars, science journalists, science educators and media educators were interviewed to determine what knowledge, skills and habits of mind they judged valuable for individuals reading science-related news stories. Teachers of science and of English from nine secondary schools in Northern Ireland addressed the same issue. A striking – and significant – finding of the study was the very substantial number of statements of knowledge, skill and disposition offered by participants that relate to ‘media awareness’, an issue largely overlooked in the science education literature. The school-focused phase of the research suggests that cross-curricular approaches involving teachers of science collaborating with those of English/media education or media studies may best serve to address this important curricular goal.     

Assessments to evaluate bilinguals: The overdue discussion of the deaf and hard of hearing student population in the United States

Assessment is a major part of the United States schooling system. Legal requirements make assessment a large part of practitioner responsibilities. The significance of assessment is, even more, the case for special populations such as bilingual hearing and Deaf and Hard of Hearing students, groups that are often the target of concern for English language development delays, differences, and/or disorders. In this article, we discuss the issues around assessing the language of Deaf and Hard of Hearing bilingual students in the United States. We highlight parallels between Deaf Education and hearing bilingual education in regard to language assessment, as well as discuss important distinctions such as the placement of Deaf Education within Special Education and working with two or more language modalities (e.g., signed, spoken, and written). In addition, alternative language assessment practices are discussed. We close this article by proposing ways for practitioners to satisfy legal and field mandates to assess Deaf and Hard of Hearing students while also applying best practices for assessing language skills in bilingual populations.     

Changes in instructors' assessment thinking related to experimentation with new strategies

Formative assessment has been recognised as a critical element in teaching for conceptual development. A case study research design was employed to: (1) characterise the assessment thinking of three science instructors at a research‐based university; and (2) examine the complex relationship between instructor thinking and practice by encouraging experimentation with alternative assessment strategies. Interviews, reflective journals, field notes and course documents were the data sources used to create a single case study that documented the development of these university instructors’ assessment thinking during their experimentation with formative assessment strategies. Throughout two semesters of experimentation, the instructors’ assessment thinking became more sophisticated; they grew to view the purpose of assessment less as a summative activity used for the assignment of marks and more as a tool for diagnosing student learning. However, more sophisticated thinking was not associated with revisions in teaching practice based on formative assessment data. Further investigations are needed to more completely understand the nature of assessment thinking and how assessment thinking influences assessment practices. Implications for professional development of university‐level science instructors include personalised experiences through which instructors can become active participants in gathering evidence of student learning that promotes growth in assessment thinking.

A systematic review of trends and findings in research employing drawing assessment in science education

ABSTRACT

In this study, we reviewed 76 journal articles on employing drawing assessment as a research tool in science education. Findings from the systematic review suggest four justifications for using drawing as a type of research tool, including assessment via drawing as (a) an alternative method considering young participants’ verbal or writing abilities, and affective or economic reasons, (b) a unique method that can reveal aspects not easily measured by other methods, (c) a major method that reflects characteristics of science subjects, and (d) a formative assessment to diagnose students’ ideas to benefit their learning. Furthermore, five research trends of studies using drawing as assessment tools are identified, including: (a) students’ conceptions of scientists from the Draw-a-Scientist-Test (DAST) and evolving studies, (b) students’ understanding or mental models of science concepts, (c) participants’ conceptions of science learning or teaching, (d) students’ inquiry abilities and modelling skills via drawing, and (e) technology to support drawing. For each trend, we synthesised and commented on the current findings. A framework conceptualising phases and issues when designing research and instruments employing drawing assessments is proposed. The review provides insights into the design and future direction of research employing drawing assessments in science education.
