Can the Engagement Model act as a replacement for the P-scale assessment system?

The Engagement Model was launched in January 2020, endeavouring to address the weaknesses of the P-scales assessment for students not yet involved in a subject-specific curriculum. This paper will discuss how and if the tensions between previously adopted assessment systems as discussed in teacher interviews can be reconciled through the Engagement Model in relation to students with autism and severe learning difficulties. The interview findings suggested that some of the problems with assessment, when applied in this context, are related to consistency and transferability, lack of formal recognition of non-academic progress, familiarity with the students, observation skills and training, workload and time, and subjectivity of judgement amongst professionals. When compared with the aims of the Engagement Model, the findings of the research suggest that even though it addresses some of the issues raised, it cannot act as a substitute to the P-scale system as it serves a different purpose.     

‘Grasp of Practice’ as a Reasoning Resource for Inquiry and Nature of Science Understanding

This article articulates how a ‘grasp of practice’ serves as a reasoning resource for inquiry and citizenship abilities associated with nature of science (NOS) understanding. Theoretically, this resource is elaborated through an overlapping concern with ‘practice’ in two literatures, science studies and psychology of learning, bringing attention to two key roles in scientific practice, Critiquers and Constructors of claims. Empirically, this resource is made plausible by the results of an expert-novice study and a classroom study. In the expert-novice study, reactions of scientists and laypeople to science-related claims in the popular media were contrasted, underlining the appropriate ways scientists tend to Critique such claims. In the classroom study, sixth-grade students engaged in a 2-week ramp experiment, experiencing first hand the roles of Critiquers and Constructors of claims, and were subsequently assessed with a novel experimental task. Performances suggest that students had attained a grasp of practice, going well beyond mere execution of methods or procedures. These results challenge a common assumption that declarative knowledge best characterizes learning targets for supporting inquiry and NOS understanding.

Design of a student lab program for nanoscience and technology – an intervention study on students’ perceptions of the Nature of Science,the Nature of Scientists and the Nature of Scientific Inquiry

Background: This article describes the design and the evaluation of a student lab program on the topic of nanoscience and technology (NST), mainly focusing on Nanoscience and its applications. The program was designed for students in grades 8–10 and was part of a larger outreach program of the Collaborative Research Center ‘Function by Switching’ at Kiel University. The Model of Educational Reconstruction (MER) served as a framework for the research-based design of the student lab.

Purpose: We aimed to develop an authentic science activity in the area of NST in order to support scientific inquiry learning and to provide a deeper understanding of scientific topics.

Sample: A total of 154 secondary school students from grades 8–10 of seven different secondary schools participated in this study.

Design and methods: A pre-post questionnaire with six subscales on students’ perceptions of the Nature of Science (NOS), Scientific Inquiry (NOSI) and the involved scientists (NOST) in the area of nanoscience and nanotechnology was applied.

Results: Results show that the applied explicit and reflective approach embedded in the nanoscience content significantly improved the participating students’ perceptions of NOS, NOSI and NOST facets. After the lab visit, students’ answers corresponded to a more adequate perception of today’s science and scientists. Some gender differences in learning gains were also detected.

Conclusion: The study served its main purpose which was to investigate a well-balanced strategy to develop authentic out-of-school-learning environments with a focus on NOS/NOSI/NOST. Testing students’ perceptions of the nature of nanoscience provided insights into students’ worlds and served as feedback for the lab program. The outcomes of this study might help to better understand and further develop authentic (nano)science programs in out-of-school settings and science outreach programs.

Do the Modern Neurosciences Call for a New Model of Organizational Cognition?

Our purpose in this paper is to try to make a significant contribution to the analysis of cognitive capabilities of the organization of active social systems such as the business enterprise by re-examining the concepts of organizational intelligence, organizational memory and organizational learning in light of the findings of modern neuroscience. In fact, in this paper we propose that neuroscience shows that sociocognitivity is for real. In other words, cognition, in the broad sense, is not exclusive to living organisms: Certain kinds of social organizations (e.g. the enterprise) possess elementary cognitive capabilities by virtue of their structure and their functions. The classical theory of organizational cognition is the theory of Artificial Intelligence. We submit that this approach has proven to be false and barren, and that a materialist emergentist neuroscientific approach, in the tradition of Mario Bunge (2003, 2006), leads to a far more fruitful viewpoint, both for theory development and for eventual factual verification. Our proposals for sociocognitivity are based on findings in three areas of modern neuroscience and biopsychology: (1) The theory of intelligence and of intelligent systems; (2) The neurological theory of memory as distributed, hierarchical neuronal systems; (3) The theory of cognitive action in general and of learning in particular. We submit that findings in every one of these areas are applicable to the social organization.     

The “Species” Concept as a Gateway to Nature of Science

The nature of science (NOS) is a primary goal in school science. Most teachers are not well-prepared for teaching NOS, but a sophisticated and in-depth understanding of NOS is necessary for effective teaching. Some authors emphasize the need for teaching NOS in context. Species, a central concept in biology, is proposed in this article as a concrete example of a means for achieving increased understanding of NOS. Although species are commonly presented in textbooks as fixed entities with a single definition, the concept of species is a highly discussed one in the science and the philosophy of biology. A multitude of species concepts exist, reflecting both the views and interests of researchers and their utility in different organism groups. The present study serves to address the following questions: How do textbooks in Norwegian primary and lower secondary schools present the concept of species? Can inquiries into the concept of “species” serve to highlight aspects of NOS? A review of the available literature on species and species concepts in school is also performed. In the schoolbooks, the biological species concept is commonly used as the main definition, whereas the morphological species concept is represented by additional remarks of similarity. The potential and pitfalls of using the species concept for teaching NOS are discussed, with NOS being discussed both as a family resemblance concept and as a consensus list. Teacher education is proposed as a starting point for inducing a more sophisticated view of biology into schools.

Emerson’s Nature as an Early Manifestation of the Biological Sublime

Ralph Waldo Emerson’s first essay, Nature, has been viewed as a reconciliation of the world of nature with the world of mind. A close analysis shows that Emerson was in fact attempting to come to terms with human fragility in a unique way by delineating the point at which the worldly and the transcendental are demarcated. Because nature as we normally apprehend it merely displays a physical remainder, an alternative way of coping with grief is to change the very way we apprehend nature itself. Moreover, the way forward is not merely to change our perceptions, but truly to conform ourselves with the natural workings of the universe in a manner that has been forgotten, obliterated or never even previously conceived. In short, Nature can be reconsidered as an early example of the biological sublime.     

In and out of the STEM pipeline – a longitudinal study of a misleading metaphor

ABSTRACT

The metaphor of the leaking pipeline is sometimes used to suggest that some students are lost for STEM as they advance through the educational system. This paper follows a cohort of upper-secondary school students with an interest in STEM from 18 months before their completion of upper-secondary until three years after their completion. Adopting a mixed-methods design, it follows the students' reflections and interests concerning their choice of higher education programme within and/or outside STEM. Only 22% of the students expressed the same interest during the whole period, and 56% changed between different groups of studies, e.g. between STEM and HEALTH. The students' trajectories showed that the leaking-pipeline metaphor is misleading because it suggests a linear and one-way movement, while there were students moving in as well as out of STEM trajectories. The students’ reflections showed identity issues at the level of ego identity, the personal identity and the social identity (Coté and Levine). Particular incidents in the students’ lives and in the outreach programme they were involved in sparked interests and reflections. These incidents should be considered as elements in a continuous reflection concerning who they are and where they would like to go rather than as critical moments.     

Capturing the Transformation and Dynamic Nature of an Elementary Teacher Candidate’s Identity Development as a Teacher of Science

This study examines the transformation and dynamic nature of one teacher candidate’s (Susan) identity as a learner and teacher of science throughout an innovative science methods course. The goal of this paper is to use theoretically derived themes grounded in cultural-historical activity theory (CHAT) and situated learning theory to determine the ways in which Susan’s identity as a learner and teacher of science was influenced by her experiences in the course, and to describe how she made meaning of her transformative process. The following are the three theoretical themes: (1) learning contributes to identity development, (2) identity development is a dialogical process that occurs between individuals, not within individuals, and (3) social practice leads to transformations and transformations lead to the creation of new social practices. Within each theme, specific experiences in the science methods course are identified that influenced Susan’s identity development as a teacher of science. Knowing how context and experiences influence identity development can inform design decisions concerning teacher education programs, courses, and experiences for candidates.

Perspectives of ‘STEM education and policies’ for the development of a skilled workforce in Australia and India

ABSTRACT

In an increasingly competitive world, it has been proved that invention, development, and profusion of new technologies through science and technology are the fundamental source of economic progress. Australia, which is one of the world leaders in education and India, which has the capacity to produce the highest number of young skilled manpower to lead the world, both understand the current situation and have signalled their commitment to restoring the national strategy for STEM education. The proposed study focuses on a comparative understanding of the interplay of inclusive policies, government’s initiatives, knowledge gap from the literature and potential future challenges that Australia and India could face in STEM education at the school level. The question we asked is: what are the important inferences and best practices in STEM education that can be mutually beneficial to broaden the Strategic Partnership? It is identified that the governments of both the countries are determined to utilise the young population to train them as skilled workforce in order to meet the future demand of industries. Australia’s constructivist approach to education and the well-defined system of vocational training outperform India, which is still following the traditional approach. However, Australia has failed to engage students adequately in STEM and needs to revisit the efficacy of the current education model, while India needs to espouse the well-defined Australian framework, which could help to enhance quality infrastructure, curriculum, constructivist teaching and transparent policy implementation. In addition, both the nations must work hard to attract bright students in the teaching profession in order to promote a conducive environment for scientific learning.     

Grade 12 French Students’ use of a Thermodynamic Model for Predicting the Direction of Incomplete Chemical Changes

The authors of the current chemistry curriculum—implemented in Grade 12 in France—provided a criterion of change allowing prediction of direction of chemical changes and pointed out the difference to be made between experimental facts and models. A study analysing part of the curriculum content and the effects of teaching this content on students’ reasoning was conducted. The content analysis presents the functioning of the thermodynamic model, which highlights the links to be made between the experimental situation and the model when predicting the direction of a chemical change. This functioning specifies the role of the chemical equation and that of the criterion of change (comparing the reaction quotient to the equilibrium constant) and stresses the crucial points that may lead to misunderstandings. Written tests were administered to students after teaching them to determine how they predicted the direction of a chemical change, and whether they made a relevant choice between using the chemical equation and using the criterion of change and a clear distinction between the experimental situation and the thermodynamic model. Few students had a good understanding of the respective roles of the criterion and the chemical equation. A majority used the criterion to predict the direction of chemical changes relevantly, but correct answers were not widespread. Two particular mistakes, the modification of the expression of the reaction quotient and the prediction of a change despite a missing reactant, revealed that students do not properly understand the difference and the relationship between the experimental situation and the thermodynamic model.     

Does ACCEL Excel as a Model of Giftedness? A Reply to Commentators

In this essay, I respond to commentators on my article on the Active Concerned Citizenship and Ethical Leadership (ACCEL) model for understanding giftedness. I cover a number of topics that arose in or out of the commentaries, in particular, systems inertia; toxic leadership; teaching for creativity; flight from reality; the role of science, technology, engineering, and mathematics (STEM) in teaching for wisdom; the developmental nature of giftedness; making a positive, meaningful, and enduring difference; IQ as a diagnostic tool rather than as a gatekeeper; meeting the needs of marginalized young people; teacher education; and retrospective studies. I conclude that the differences among all of us in this symposium are small and that we all agree that a model like ACCEL—whatever its exact terms—is needed to move the field of giftedness beyond a preoccupation with abilities, narrowly defined.     

Science Teachers’ Use of a Concept Map Marking Guide as a Formative Assessment Tool for the Concept of Energy

In this study, we investigated the value of a concept map marking guide as an alternative formative assessment tool for science teachers to adopt for the topic of energy. Eight high school science teachers marked students’ concept maps using an itemized holistic marking guide. Their marking was compared with the researchers’ marking and the scores of a multiple-choice diagnostic test. Statistical analysis revealed that teachers evaluated students’ concept maps consistently, but the concept map scores were only mildly correlated with the multiple-choice test scores. We explored what each assessment method revealed in terms of students’ understanding with one student’s performance as a showcase. Teachers’ views on using the marking guide of concept maps as an assessment tool were also included. We discuss the value of the concept map marking guide as a formative assessment tool for science teachers to create and modify in order to encourage students’ conceptual learning.
