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.     

An exploratory investigation of teaching innovations and learning factors in a lean manufacturing systems engineering course

The use of collaborative activities and simulation sessions in engineering education has been explored previously. However, few studies have investigated the relationship of these types of teaching innovations with other learner characteristics, such as self-efficacy and background knowledge. This study explored the effects of collaborative activities and simulation sessions on learning and the relationships between self-efficacy beliefs, background knowledge, and learning. Data were collected from two different terms in an upper division engineering course entitled Lean Manufacturing Systems Engineering. Findings indicated that the impact of collaborative activities and simulation sessions appears to be different, depending on the concepts being taught. Simulation sessions were found to have a significant effect on self-efficacy beliefs, and background knowledge had a mixed effect on learning. Overall the results of this study highlight the complex set of relationships between classroom innovations, learner characteristics, and learning.     

Creating a dialogic environment for transformative science teaching practices: towards an inclusive education for science

Abstract

This paper focuses on the design and application of a teacher training strategy to promote the inclusive education of students with disabilities in the science classroom, through the creation of adult learning environments grounded on the principles of dialogic learning. Participants of the workshop proposal consisted of a group of twelve teachers who were working at various educational levels. Teacher teams proposed and implemented in their classroom, innovative, inclusive science-learning activities about a topic of their choice. Data were collected from interviews with teachers five months after the courses, teachers’ portfolios about their practice during implementation of such sequences, and researchers’ observations. The data suggest that it is possible to stimulate a gradual transformation of teaching practices through a teacher training proposal that promotes self-awareness and critical reflection, situated in the creation of meaning and a willingness to change in the spirit of solidarity and social action. We found elements to recommend the incorporation of these innovations at the curricular and practical level for teacher training schools and for in-service teacher development programmes in Mexico and elsewhere.     

Memorisation methods in science education: tactics to improve the teaching and learning practice

How can science teachers support students in developing an appropriate declarative knowledge base for solving problems? This article focuses on the question whether the development of students’ memory of scientific propositions is better served by writing propositions down on paper or by making drawings of propositions either by silent or muttering rehearsal. By means of a memorisation experiment with eighth- and ninth-grade students, we answer this question. In this experiment, students received instruction to memorise nine science propositions and to reproduce them afterwards. To support memorisation students were randomly assigned either to a group that received instruction to write each proposition on paper or to a group that received instruction to make a drawing about the content of the proposition. In addition, half of the students in both groups received instruction to mutter and the other half of them received instruction to write or draw in silence. The main conclusion from the experiment is that after four weeks students who had made a drawing remembered significantly more propositions than those who had memorised the propositions by writing them down. Our research further revealed that it did not matter whether students muttered or memorised silently.

Rethinking science education: Beyond piagetian constructivism toward a sociocultural model of teaching and learning

In the first part of the article I present an epistemological critique of forms of pedagogy founded on Piagetian constructivism. Despite the appeal of the notion that learners construct their understanding, I argue that constructivism is problematic because it ignores the subjectivity of the learner and the socially and historically situated nature of knowing; it denies the essentially collaborative and social nature of meaning making; and it privileges only one form of knowledge, namely, the technical rational. I then present a critique of active learning and student-centered forms of pedagogy. I argue that in our models of teaching we rely on too many unexamined assumptions from developmental psychology and we take for granted the problematic notion that children learn by doing. My central thesis is that constructivism is flawed because of its inability to come to grips with the essential issues of culture, power, and discourse in the classroom. In the concluding section of the article I present a preliminary account of a sociocultural approach to teaching and learning that takes seriously the notion that learning is situated in contexts, that students bring their own subjectivities and cultural perspectives to bear in constructing understanding, that issues of power exist in the classroom that need to be addressed, and that education into scientific ways of knowing requires understanding modes of classroom discourse and enabling students to negotiate these modes effectively so that they may master and critique scientific ways of knowing without, in the process, sacrificing their own personally and culturally constructed ways of knowing.     

Research-based education as a model to change the teaching and learning environment in STEM disciplines

This paper discusses the benefits and threats of promoting and reinforcing a research-based education environment to STEM undergraduate students. The paper explores the rationale for research-based education as a pedagogical driven approach, where undergraduate students learn through enquiry and discovery. Research evidence of a STEM case study conducted in an English university is then presented, which sheds light on how this institution and STEM research-active academics are fostering students’ learning in a research-based education environment, the constraints they face, and the pedagogical solutions they propose to empower students’ learning. The paper concludes with a set of recommendations aimed to raise the research-based education environment of STEM Faculties or Departments.     

Status of science education in state departments of education: An initial report

The past five years have been characterized as times of assessment in science education. One aspect of the profession where little information has been reported is the service and leadership provided by the various Departments of Education that exist as a part of the 50 state governments. Information was collected from the 50 states concerning the professional preparation of state science consultants, the nature of the positions, number of workers employed in such units, changes in support staff, facilities, and budget for each five year interval between 1960-1980. Science consultants are 46 years of age, have completed more than 10 years of classroom teaching, have been supervisors at the last level, have been in state positions for one-eight years, and have a Master's degree (half have the Ph.D.). Science consultants in the state department of education work in local schools, write proposals, assist with other administrative duties, work as members of evaluation teams. They spend two-thirds of their time in science education per se. The duties have become more general with less time spent exclusively on science education duties. The positions have become more involved with regulations, evaluations; the consultants enjoying less flexibility in their jobs. There has been a decline in terms of numbers of consultants, budget for science education; and general support for science education projects in state departments of education during the 20-year period surveyed.     

Teacher as knower and learner: Reflections on situated knowledge in science teaching

I argue from an understanding of current feminist philosophy that a teacher's practice reflects changing experiences, knowledge, values, and identities, and as such can be productively thought of as a site for learning as much as a site for expounding upon what is known. This suggests a vision for what constitutes effective practice different from that commonly held in science. I argue that praxis proceeds from the personal epistemological standpoints of the teacher (defined as standpoint theory). This knowledge is only partially applicable to particular situations in the classroom. The hallmark of feminist pedagogy, if conceptualized as derivative from standpoint theory, is to “take everyday life as problematic” (Smith, 1991, p. 88). Implicit in such a conceptualization is that pedagogy starts from an explicit recognition of everyday life and both builds from and questions that beginning. This is true for students and also for the teacher, and is the root of my claim that through teaching, the teacher becomes a learner. The immediate circumstances in which teaching occurs present different and unique qualities from those in which the teacher's knowledge and value were created. As a teacher, I am therefore continuously confronted with the inadequacy of my knowledge. The circumstances and children's activities tell me that I need to do things differently. In this situation, the act of teaching as an assertion of knowing becomes a recognition of not-knowing. Teaching becomes an occasion for learning about subject matter, children, and self. I recount an example of teaching in a first-grade classroom to give this argument substance. This story is an example from my own teaching in which parallels between scientific theorizing and storytelling are drawn and capitalized upon as a vehicle for critical thinking in science. This became an occasion for reflecting upon the appropriateness of those values because of the multicultural qualities of the classroom. J Res Sci Teach 35: 427–439, 1998.     

SciEthics Interactive: science and ethics learning in a virtual environment

Learning in immersive 3D environments allows students to collaborate, build, and interact with difficult course concepts. This case study examines the design and development of the TransGen Island within the SciEthics Interactive project, a National Science Foundation-funded, 3D virtual world emphasizing learning science content in the context of ethical dilemmas. The 2 year development process is examined through the lens of the rapid prototyping instructional design model, following the project from conceptualization to implementation of a 3D simulation. Through expert interviews, focus groups, and working groups, we were able to determine critical scientific and ethical issues to present to learners in the virtual world. We collected data on 53 students using the simulation at universities in the United States and South Africa and evaluated their experience using qualitative and quantitative methods. Results showed that student participants were engaged and motivated by the simulation. The students reported an increase in science knowledge and ethical understanding, but individual experiences varied.     

Graduate learning outcomes in science: variation in perceptions of single- and dual-degree students

The development of transferrable skillsets, articulated in statements of graduate learning outcomes, is emphasised in undergraduate science degree programmes. Science students enrolled in dual (double) degrees comprise a significant minority of Australian science undergraduates. Research comparing perceptions of single and dual degree students on their science learning outcomes has rarely been explored. The Science Students Skills Inventory was used to compare the perceptions of single (n = 640) and dual (n = 266) degree undergraduate science students. The instrument explored science graduate learning outcomes across six indicators: importance; the extent to which outcomes were included; the extent to which they were assessed; improvement; confidence; and likely future use. Analysis of findings, employing the planned–enacted–experienced curricula framework, offers insight into potential avenues towards coherence of the experienced curriculum by arguing the need for shared perceptions of graduate learning outcomes for single and dual degree science students. The key contribution of this study is a shift towards progressive curriculum development that draws on both single and dual degree student perspectives to achieve graduate learning outcomes. Recommendations include: whole-of-programmes curricular pathways premised on progressive development of learning outcomes that are inclusive of dual degree students, explicit interdisciplinary learning opportunities, and adoption of dual/single status as a demographic variable reported in future research.     

Embodied learning and teaching approaches in language education: A mixed studies review

The notion of embodied learning has gained ground in educational sciences over the last decade and has made its way to language education with researchers acknowledging language learning as an embodied process. This mixed studies review aggregates and reviews empirical research, published from 1990 to 2020, using embodied learning approaches in language education. The review focuses on embodied approaches in learning and teaching first, second, and foreign languages at various educational levels. It encompasses 41 empirical studies with a majority published between 2019 and 2020, suggesting that the research area is growing rapidly. The results show that the studies align with two strands: (1) embodied learning through orchestrating embodied language learning and teaching, and (2) embodied learning in naturally occurring language learning interactions. The review identifies various embodied learning activities and presents how they contribute to language learning and teaching in different ways. The review proposes an understanding of embodied language learning that holds potentials to engage learners holistically, while simultaneously promoting language learning skills and adding emotional and motivational benefits to language learning.     

Experienced teachers' knowledge of teaching and learning of models and modelling in science education

This article reports a study of the knowledge of experienced science teachers in the context of a reform in science education in The Netherlands. The study focused on a major goal of the reform, that is, improving students' knowledge and abilities in the field of models and modelling in science. First, seven teachers of biology and chemistry were interviewed about the teaching and learning of models and modelling in science. Next, a questionnaire was designed consisting of 30 items on a Likert-type scale. This questionnaire was completed by a group ( n = 74) of teachers of biology, chemistry and physics. Results indicated that the teachers could be grouped in two subgroups, who differed in terms of their self-reported use of teaching activities focusing on models: one sub-group applied such activities substantially more often than the other sub-group. This distinction appeared not to be related to the teachers' subject, or teaching experience. Moreover, the use of teaching activities seemed only loosely related to the teachers' knowledge of their students, particularly, students' views of models and modelling abilities. Implications for the design of teacher education are discussed.
