Learning of Chemical Equilibrium through Modelling‐based Teaching

This paper presents and discusses students’ learning process of chemical equilibrium from a modelling‐based approach developed from the use of the ‘Model of Modelling’ diagram. The investigation was conducted in a regular classroom (students 14–15 years old) and aimed at discussing how modelling‐based teaching can contribute to students learning about the main qualitative aspects concerning chemical equilibrium. The data (collected from the written material produced by the students and the video‐recording of the classes) were organised in case studies for each group of students. The discussion supports the conclusion that elements from the ‘Model of Modelling’ diagram, as well as methodological aspects related to the teacher’s action, influenced the students’ learning process.     

A computer‐based learning environment in the field of Newtonian mechanics

This paper describes a Computer‐based Learning Environment (CBLE) whose objective is to stimulate and support learning in the field of Newtonian mechanics through exploratory activities in various microworlds. The structure of the microworld TABLE is described in detail. A pilot study is presented: it concerns the modelling process of the learner knowledge in the topic involved and the evaluation of the impact of the exploratory activity on student learning. Some suggestions drawn from the results are discussed.     

An Example of Large‐group Drama and Cross‐year Peer Assessment for Teaching Science in Higher Education

Undergraduate students pursuing a three‐year marine biology degree programme (n = 86) experienced a large‐group drama aimed at allowing them to explore how scientific research is funded and the associated links between science and society. In the drama, Year 1 students played the “general public” who decided which environmental research areas should be prioritised for funding, Year 2 students were the “scientists” who had to prepare research proposals which they hoped to get funded, and Year 3 students were the “research panel” who decided which proposals to fund with input from the priorities set by the “general public”. The drama, therefore, included an element of cross‐year peer assessment where Year 3 students evaluated the research proposals prepared by the Year 2 students. Questionnaires were distributed at the end of the activity to gather: (1) student perceptions on the cross‐year nature of the exercise, (2) the use of peer assessment, and (3) their overall views on the drama. The students valued the opportunity to interact with their peers from other years of the degree programme and most were comfortable with the use of cross‐year peer assessment. The majority of students felt that they had increased their knowledge of how research proposals are funded and the perceived benefits of the large‐group drama included increased critical thinking ability, confidence in presenting work to others, and enhanced communication skills. Only one student did not strongly advocate the use of this large‐group drama in subsequent years.     

Effects of Model‐based Teaching on Pre‐service Physics Teachers’ Conceptions of the Moon,Moon Phases,and Other Lunar Phenomena

The purpose of this study was twofold. First, it was aimed to identify Turkish pre‐service physics teachers’ knowledge and understanding of the Moon, Moon phases, and other lunar phenomena. Second, the effects of model‐based teaching on pre‐service teachers’ conceptions were examined. Conceptions were proposed as mental models in this study. Four different questionnaires including 22 generative, explanation, and factual questions were used through the study. The pre‐service physics teachers’ mental models generated in response to lunar phenomena might be representations of their naïve knowledge as a result of their causal observations and experiences with the world, and their misconceptions as a result of inconsistencies between their naïve knowledge and scientific knowledge. Therefore, the pre‐service teachers’ mental models were categorized based on the work by Chi and Roscoe. Some of the pre‐service teachers’ mental models shifted from flawed or incomplete mental models to correct mental models of the Moon and lunar phenomena with the facilitation of model‐based teaching. The conclusions of the study carry implications for curriculum developers and teacher education.     

Effects of Problem-Based Learning on University Students’ Epistemological Beliefs About Physics and Physics Learning and Conceptual Understanding of Newtonian Mechanics

This study investigated the effects of problem-based learning on students’ beliefs about physics and physics learning and conceptual understanding of Newtonian mechanics. The study further examines the relationship between students’ beliefs about physics and their conceptual understanding of mechanics concepts. Participants were 124 Turkish university students (PBL = 55, traditional = 69) enrolled in a calculus-based introductory physics class. Students’ beliefs about physics and physics learning and their physics conceptual understanding were measured with the Colorado Learning Attitudes about Science Survey (CLASS) and the Force Concept Inventory (FCI), respectively. Repeated measures analysis of variance of how PBL influence beliefs and conceptual understanding were performed. The PBL group showed significantly higher conceptual learning gains in FCI than the traditional group. PBL approach showed no influence on students’ beliefs about physics; both groups displayed similar beliefs. A significant positive correlation was found between beliefs and conceptual understanding. Students with more expert-like beliefs at the beginning of the semester were more likely to obtain higher conceptual understanding scores at the end of the semester. Suggestions are presented regarding the implementation of the PBL approach.     

Linguistic‐minority Students and Bilingual Mathematics Teaching

Mathematics teaching and subject‐matter acquisition of two groups of linguistic minority students were studied; one in a minolingual second‐language class and the other in a traditional bilingual‐education model in the city of Oslo, Norway. The background of attempts at bilingual education in the Norwegian context is presented, and some aspects of bilingual education, bilingual pedagogy and research‐based perspectives on the role of bilingual education in subject‐matter acquisition is discussed. On the basis of an empirical study of the teaching situation of linguistic‐minority students it is concluded that linguistic‐minority students profit from bilingual mathematics teaching. The empirical research results indicate that linguistic‐minority students (LMSs) with a bilingual‐education (BE) background can achieve as good or better results in mathematics as monolingual students. The strength of bilingual education can therefore be said to reside in the favourable conditions that it creates for the comprehension of linguistic‐minority students of the content taught. By creating favourable conditions bilingual subject‐matter teaching also fulfils minorities’ expectations of participating in content‐area instruction: to understand what is being communicated in subject‐matter teaching and to learn what is normally expected to be learned in subject‐matter teaching. It is therefore legitimate to argue for bilingual education on pedagogical grounds without the support of old‐fashioned anthropological or psychological arguments.     

Design‐based science and real‐world problem‐solving

Design‐based science (DBS) is a science pedagogy in which new scientific knowledge and problem‐solving skills are constructed in the context of designing artifacts. This paper examines whether the enactment of a DBS unit supported students’ efforts to construct and transfer new science knowledge and ‘designerly’ problem‐solving skills to the solution of a new real‐world design problem in a real‐world setting. One hundred and forty‐nine students participated in the enactment of a DBS unit. Their understanding of the curricular content was assessed by identical pre‐instructional and post‐instructional written tests. They were then given a new design problem as a transfer task. There was a statistically significant increase on scores from pre‐test to post‐test with an effect size of 1.8. There was a stronger correlation between the scores of the transfer task and those of the post‐test than with those of the pre‐test; we use this finding to suggest that the knowledge that was constructed during the unit enactment supported the solution of the transfer task. This has implications for the development of science curricula that aim to lead to the construction of knowledge and skills that may be useful in extra‐classroom settings. Whether participation in consecutive enactments of different DBS units increases transfer remains to be investigated in more depth.     

Understanding and Teaching Problem‐Solving in Physics

Summaries

English

We describe a systematic study of skills for solving problems in basic physics, a domain of practical significance for instruction, but not of prohibitive complexity. Our studies show that an inexperienced student tends to solve a problem by assembling individual equations. By contrast, an expert solves a problem by a process of successive refinements, first describing the main problem features by seemingly vague words or pictures, and only later considering the problem in greater detail in more mathematical language. We have formulated explicit theoretical models with such features and have supported them by some detailed observations of individuals. In addition, experimental instruction incorporating such features seems to improve problem‐solving performance significantly. These investigations yield thus some basic insights into thinking processes effective for problem‐solving. Furthermore, they offer the prospect that these insights can be used to teach students improved problem‐solving skills and to modify common teaching practices which inhibit the development of such skills.     

The Acquisition of Science‐related Attitudes and its Relationship to Pre‐student Teaching Experience

It is desirable that secondary school science teachers should, in addition to acquiring factual knowledge in the content area of science, also develop favourable science‐related attitudes. The present science teacher education programmes provided in Teachers’ Colleges in Nigeria make provisions for the acquisition of factual knowledge in science. However, it is assumed that positive science‐related attitudes would be incidentally acquired as secondary product of cognitive outcomes.

This paper is a report of a study in which an instructional package‐‐the Introductory Science Teacher Education (ISTE)‐‐was designed to promote in pre‐service science teachers the acquisition of favourable science‐related attitudes.

A trial administration of the ISTE was carried out in the study. Then the effect of the ISTE on students exposed to it was determined in terms of acquisition of science‐related attitudes and competence in lesson preparation.

The results obtained confirmed that the ISTE could produce better science‐related attitudes than the traditional science teacher education programme. The superiority of the effect of the ISTE on lesson preparation competence of pre‐service science teachers was also established in the study. Thus, a case is made for the need for such a package as the ISTE in science teacher education programmes.     

Academics' Motivation and Self‐efficacy for Teaching and Research

The study focused on academic staff in a post‐1987 university, that is, a former college of advanced education which had been awarded university status as a result of the Australian Government's decision to have a Unified National System of universities. The focus of attention was motivation and self‐efficacy for teaching and research. The effect of faculty of affiliation, level of appointment, gender, qualifications, and research productivity on staff's self‐reported attributions for teaching and research were examined. Tutors, staff with bachelor degrees, academics with low research productivity, and women had higher teaching motivation. One faculty was lower in both research motivation and self‐efficacy, and associate professors and professors had high levels of research efficacy. Men and women had the same level of research motivation and self‐efficacy. Staff with higher degrees and greater research productivity were more motivated and self‐efficacious about research. The results suggest the need to understand more clearly how each individual's research motivation and self‐efficacy is constructed and to determine the best method of increasing motivation and self‐efficacy for teaching and research.     

A Motivational View of Constructivist‐informed Teaching

Constructivist and conceptual change perspectives on learning have given rise to a number of models of constructivist classroom teaching. Motivation has been recognized as an important factor in the construction of knowledge and the process of conceptual change, so one could expect that motivation strategies would be integral components of constructivist‐informed teaching. The purpose of this paper was to examine, by literature review, the extent to which motivation strategies have been included in extant models of constructivist‐informed teaching. The study involved the development of a list of motivation strategies, based on current motivation constructs. Several constructivist‐informed teaching models were then analysed. It was found that these models were rather limited in the extent to which they had explicitly integrated motivation. It was also found that some aspects of the models were not entirely in accord with current views of motivation. Finally, a motivational model of constructivist‐informed teaching was developed and its three components were described.

The problem of education‐based discrimination

While the research, theory and policy literature on race, class and gender discrimination in education is extensive, the problem of education‐based discrimination itself has been widely overlooked. Indeed, the dominant ideologies of meritocracy and human capital (into which we are inculcated throughout our lives by schools, media and the state) proclaim that higher levels of education are and should be linked with greater reward. In a world where education is regularly invoked to legitimate inequality, it can appear nonsensical even to raise concern about education‐based discrimination as a matter of social injustice. We need, however, to challenge those who have taught us not to see what has essentially become an elephant in our living room. Otherwise, we will find ourselves unable ever to use our public systems of education for universal emancipation and empowerment.     

Teaching Statistics Visually: A Quasi‐Experimental Evaluation of Teaching Chi‐Square through Computer Tutorials 1

This paper examines the effectiveness of computer graphic tutorials in explaining statistical concepts to undergraduates enrolled in two sections of criminal justice research methods. We demonstrated key concepts to a treatment group through a Microsoft Excel spreadsheet and Macromedia Flash movies. The students’ statistical skills were measured through a test on mathematical calculation and multiple‐choice questions about chi‐square concepts. Both sections scored similarly on the skills test; however, the treatment group performed better on the conceptual questions. We discuss the implications for teaching methods and statistics and offer several resources that instructors can use in their courses.     

The study of literature and culture in a web‐based environment

The rationale behind the project is based on the belief that the study of a work of literature can effectively open a window of opportunity for pupils to study other countries’ cultures and identities as well as contribute to pupils’ own identity construction and to the understanding of the identity of others. Information and communication technologies serve as an educational catalyst for collaborative learning which transcends national boundaries and presents pupils with the opportunity to study cultural and identity similarities and differences, to strengthen their national identities and, at the same time, to appreciate the characteristics of other identities and cultures.

L’étude de la Littérature et de la Culture dans un environnement fondé sur la Toile

L’idée qui sous‐tend ce projet repose sur le fait que l’on croit que l’étude d’une ?uvre littéraire peut effectivement constituer une fenêtre pour les élèves, l’occasion d’étudier les cultures et les identités d’autres pays tout en contribuant à la construction de la propre identité de ces élèves et à la compréhension de l’identité des autres. Les TIC servent de catalyseur éducatif pour faciliter l’apprentissage collaboratif qui transcende les frontières nationales et offre aux élèves l’occasion d’étudier les ressemblances et les différences de cultures et d’identités, de renforcer leurs identités nationales et en même temps d’apprécier les caractéristiques d’autres identités et cultures.

Das Studium von Literatur und Kultur in einer Web‐basierten Umgebung

Die logische Grundlage dieses Projekts ist die Überzeugung, dass ein Studium im Bereich von Literatur wirksam sowohl ein Fenster zum Einblick in andere Kulturen und Identitäten öffnen kann, als auch zum eigenen Identitätsaufbau der Schüler und zum Verständnis der Identität anderer beitragen kann. ICT dient damit als Bildungskatalysator für kooperatives Lernen, damit die nationalen Grenzen überwunden werden können und bietet den Schülern die Gelegenheit, kulturelle‐ und Identitätsähnlichkeiten und Unterschiede zu erkennen, um ihre nationalen Identitäten zu stärken und gleichzeitig die Merkmale anderer Identitäten und Kulturen kennen und schätzen zu lernen.     

The Interplay of the Classroom Learning Environment and Inquiry‐based Activities

This quasi‐experimental study investigates how the classroom learning environment changed after inquiry‐based activities were introduced and student questioning was encouraged. Three science teachers and three classes of fifth graders (n=92) participated in this study. The analysis of covariance reveals that although the experimental group students perceived that their teacher’s support was significantly lower than that for the comparison group did (p< 0.05), they were significantly more involved in learning (p< 0.05) than their counterparts. Classroom observations of student questioning and inquiry activities revealed that those students with high quality levels in asking or responding to questions outperformed their counterparts in the inquiry ability of designing experimental procedures.
