A Textbook Case of the Nature of Science: Laws and Theories in the Science of Biology

The two concepts law and theory are among the most important elements of the nature of science. They represent both the tools and products of science itself. Unfortunately, the variable meanings and use of these terms in general discourse and in other school disciplines results in much confusion with respect to their proper application in a science context. The project included the design of a six-part model definition for law and theory based on a review of the literature of the philosophy of science with special reference to biology. These model definitions were then compared with those provided in a range of U.S. secondary school biology textbooks. The majority of all current major U.S. secondary school biology texts were reviewed and analyzed with respect to how the concepts of law and theory were defined and applied, in an attempt to determine whether students and teachers using such texts would gain an accurate impression of these terms and the distinction between them. This study focuses on biology instruction since a life science course is completed as a graduation requirement by virtually all U.S. high school students and as such serves as a widely shared educational experience across the nation. The term law is rarely defined in any text but various laws such as those found in genetics are frequently included as examples. The term theory is frequently defined but with a wide range of completeness of the definitions. Only rarely are theories in biology included as examples.     

Awareness and use of academic research by doctoral students

Relationships between graduate education and academic research are intuitively accepted, but have been given limited examination. Using concepts suggested by Merton and Hagstrom, this study developed measures of recognition and association to assess student awareness of ambient research in their departments. Usefulness of campus research for the respondent's own work was explored in terms of the kinds of utility and its relative importance compared to other resources. A mailed survey of a sample of Ph.D. recipients in 18 departments from a major research university brought a 68% usable return, 470 subjects. Findings show a high level of research awareness, about 70%. The major utilities of research for doctoral students are identified as the theoretical leads and basic data sources.     

Choosing competency-based,humanistic and self-directed programs: The contribution of personality and reasoning

Fifty-five college women enrolled in competency-based, humanistic or self-directed education programs completed their California Personality Inventory and listed five reasons for selecting their program. CPI results indicated that self-directed students scored lower than other students on the Femininity Scale (p.001). Using Chickering's seven vectors of change as a framework, the study found competency-based students identifying purpose and competence, humanistic students identifying inter-personal relationships and integrity, and self-directed student identifying autonomy and purpose as reasons for enrolling in their nontraditional programs. The study used these results to question the mythology that adherents to different programs are of different personality types and to argue that differences in perceptions of purpose in education distinguish students in the three programs.     

A map of postsecondary assessment

Although most discussions of postsecondary assessment focus on students' knowledge and skills, these cannot be fully understood without assessing the wasy they are influenced by other aspects of postsecondary education. These aspects are described in a map consisting of 20 points which depicts the flow of students through institutions and experiences from precollege to adulthood. Consideration of the map identifies areas where better assessments and models are needed, particularly the areas of adult learners, graduate and professional education, and the characteristics and plans of college seniors.     

Exploring the Concept of ‘Habitus’ with Preservice Teachers Through the Use of Popular School Films

The thesis of this paper is that it is a productive venture to introduce preservice students to social theories that are typically not a part of teacher preparation programs. Examples of these theories are those associated with terms such as habitus, the carnivalesque, power / knowledge, seduction, detournement, the spectacle,la perruque, (the wig), and the art of making do,as well as others. In this paper, I describe a project that involved exploring the theory of habitus to problematize the tendency of preservice students to not think in terms of relations between what goes on in the classroom and what goes on in society. I introduced habitus by having preservice students read selected print materials and by having them view, analyze, and respond in writing to popular school films. Students also analyzed their experiences in classrooms in terms of habitus, making a connection between theory and practice.     

Influence of problem familiarity on learning in a problem-based course

The results of an experimental study investigating the influence of problem familiarity on learning in a problem-based psychology course are presented. Participants worked with either a familiar or an unfamiliar version of the same problem. The following measurements were taken (1) a measure of problem quality as perceived by students, (2) number of explanations of the problem put forward by the students while discussing it, (3) quality of learning issues derived from the discussion, (4) amount of time spent on self-study, and (5) the amount of knowledge acquired as indicated by a test. The results demonstrate that participants in the familiar problem condition perceived the problem to be of higher quality than the participants in the unfamiliar problem condition. No significant differences in learning were found. The findings do suggest, however, that problems may be improved by making them more relevant to the everyday experience of students.     

“It's Easier to Be Yourself When You Are Invisible”: Female College Students Discuss Their Online Classroom Experiences

There has been considerable scholarly interest in issues related to gender in the classroom, especially in terms of finding ways in which classrooms might be configured to be more welcoming--and less chilly--to female students. There is some evidence to suggest that the online learning environment may provide educators with opportunities to achieve a more female-friendly classroom, and this study was designed to gather information about that question. 125 female college students who had completed at least one online, college-level class were invited to discuss their experiences learning online. These data show that female college students respond to the online environment in a variety of ways. A small group of students indicated that they did not enjoy learning online, while others expressed mixed feelings. The majority, however, had positive things to say about their online classroom experiences; and of these, a large number identified anonymity as the most important positive aspect of the online learning environment.     

Visual processing during mathematical problem solving

This study investigated, in the context of mathematical problem solving by secondary school students, the nature of the visual schemata which Johnson (1987) hypothesises mediate between logical propositional structures and rich specific visual images. Four groups of grade 10 students were studied, representing all combinations of high and low operational ability in mathematics (equivalent to Johnson's logical propositional structures) and high and low vividness of visual imagery (corresponding to Johnson's rich images). The results suggested first, that success at problem solving was related to logical operational ability, but not to vividness of visual imagery. Second, a variety of visually based strategies were used during problem solving which differed in their level of generality and abstraction, and use of these strategies appeared related to either logical operational ability or vividness of visual imagery, depending on their level of abstraction. The results supported Presmeg's (1992b) continuum of abstraction of image schemata.Throughout the paper, the first High or Low denotes logical operational ability, and the second, vividness of visual imagery.     

A qualitative review of study behaviour before and during the first year of engineering studies

A review of the study behaviour of first-year Engineering students was undertaken in order to investigate two sets of influencing factors. The first part of the study reviewed these students' selfreported retrospective study behaviour in the context of secondary school Science, while the second part focused on their approaches to the study of Applied Mechanics as a core undergraduate degree course. Utilising qualitative interview data as the source of evidence, the study highlights the following important conclusions: (1) some traditional first-year students embark on their studies as much at risk academically as their nontradition counterparts; (2) many first-year Engineering students encounter workload pressures which lead to their adopting increasingly strategic approaches to their studies in individual courses; (3) the complex, qualitatively different learning needs of these students make it exceedingly difficult to design teaching programmes which will appropriately address these learning needs. The study suggests that these conclusions cannot, in spite of these difficulties, simply be ignored in the hope that they will resolve themselves.     

The decline of the nation-state and the education of national minorities

Many forces are shifting the role of the nation-state and altering our fundamental understanding of how it should function. The author argues that the transplanted European model of the nation-state has become dysfunctional, creating national minorities, serving as an ideological cloak for various forms of oppression and opposing forms of education that would promote diversity of languages and cultures. The decline of territorial sovereignty under the forces of globalization, the move to supranational forms of organization and the emergence of sub-national areas of economic and social development (often city-regions) provide a new range of opportunities for development of minority schooling.

Zusammenfassung Viele Kräfte verändern die Rolle des Nationenstaates und ändern damit auch unser grundsätzliches Verständnis zu dessen Funktion. Der Autor argumentiert, daß das übertragene europäische Modell des Nationenstaates außer Funktion gesetzt und damit nationale Minderheiten geschaffen wurden. Somit besteht ein ideologischer Deckmantel für verschiedene Arten von Unterdrückung und Widerstand gegen Erziehungsarten, die eine Vielfalt der Sprachen und Kulturen fördern würden. Der Verfall territorialer Unabhängigkeit unter den Kräften der Globalisierung, die Bewegung hin zu einer supranationalen Form der Organisation und die Schaffung regionaler Gebiete wirtschaftlicher und sozialer Entwicklung (oft Stadtbezirke) bieten neue Entwicklungsmöglichkeiten hinsichtlich der Schulbildung für Minderheiten.

Resumen Son muchas las fuerzas que están cambiando el papel que desempeña el estado-nación y que alteran nuestro concepto básico de cómo este debería funcionar. El autor argumenta que el modelo europeo trasplantado del estado-nación se ha vuelto disfunctional, creando minorías nacionales y sirviendo de manto ideológico para encubrir diferentes formas de opresión y de oposición a una educación que intenta promover la diversidad de lenguas y culturas. El ocaso de la soberanía territorial bajo las fuerzas de globalización, el cambio hacia formas de organización supranacionales y el surgimiento de sectores subnacionales de desarrollo económico y social (frecuentemente en regiones urbanas) proveen un nuevo tipo de oportunidades para el desarrollo de una educación escolar de minorías.

Résumé De nombreuses pressions modifient le rôle de l'Etat-nation et transforment notre conception fondamentale de son fonctionnement. L'auteur expose que le modèle européen d'Etat-nation qui a éé transposé dans d'autres régions est maintenant atteint de dysfonctionnement, car il crée des minorités nationales, sert de prétexte idéologique à différentes formes d'oppression et fait obstacle à des modèles d'éducation qui encourageraient la diversité des langues et des cultures. Le déclin de la souveraineté territoriale sous la pression de la mondialisation, l'évolution vers des formes d'organisation supranationales et l'apparition de concentrations régionales du développement éconnomique et social (souvent en tant que régions urbanisées) constituent de nouveaux stimulants pour l'élaboration d'une scolarité adaptée aux minorités.

Strategies for enhancing learning in the “blow-off” course

Lower division courses are typically perceived by students as blow-off courses. We can overcome this image. This paper contrasts active and passivelearning environments, and describes efforts to create an active, critical learning environment in both Introduction to Sociology and The Family System-typical lower division courses in Sociology. A review of grade distributions, quantitative course evaluations, qualitative course evaluations, and a survey asking students to subjectively compare the active learning course structure to the typical multiple choice format provide evaluation data. Finally, the paper discusses problems in using these innovations.Randy Stoecker recently received a Ph.D. in Sociology from the University of Minnesota, and has been exploring alternative pedagogies since 1982. He has published in the areas of social theory and social movements. An earlier version of this paper was presented at the Midwest Sociological Society Annual Meetings, Minneapolis, Minnesota, 1988.

Selbstorganisation: ein neues Paradigma für die Schulpädagogik — oder alter Wein in neuen Schläuchen?

Zusammenfassung Die Schulpädagogik ist seit langem daran gewöhnt, mit Theorieangeboten aus anderen Wissenschaftsdisziplinen konfrontiert zu werden. Mit dem Paradigma der Selbstorganisation liegt gegenwärtig eine sehr komplexe Konzeption bereit, die die Schulpädagogik zur Reflexion über ihren Gegenstand Schule anregen kann. Eine von diesem Paradigma motivierte differenztheoretische Betrachtungsweise von Systemen schärft den Block für die Möglichkeiten, aber vor allem für die Grenzen eines modernene Sozialsystems, wie es die Schule heute ist. Die Fragen, ob Schule kompensatorische Erziehungsleistungen für das Familiensystem erbringen kann, ob unterrichtliches Handeln auch therapeutisches Handeln sein kann, können aus der Perspektive dieses Paradigmas beantwortet werden.

School education has long been accustomed to accommodating theories from other scientific disciplines. The paradigm of self-organization provides a complex concept which will stimulate reflection on the phenomenon of schools within educational science. Analysis of systems in the light of different theory, motivated by this paradigm, can give a clearer view of the potential and limitations of a modern social system, which is what a school now is. By employing this paradigm, answers can be found to the questions whether schools can deliver education that compensates for family systems, and whether teaching can also provide therapy.

Resumen La educación escolar desde hace mucho tiempo se ha acostumbrado a adaptar teorías de otras disciplinas científicas. El paradigma de la auto-orgnización provee un concepto complejo que estimulará la reflexión acerca de fenómeno de las escuelas dentro de la ciencia de la educación. El análisis de sistemas a la luz de una teoría diferencial, motivada por este paradigma, podrá proporcionar una visión más clara del potencial y de las limitaciones de un sistema social moderno, de lo que es una escuela ahora. Aplicando este paradigma, podrán encontrarse soluciones a los interrogantes de si las escuelas pueden proporcionar una educacíon que compense sistemas familiares, y si la enseñanza puede también redundar en terapia.

Résumé L'éducation scolaire est depuis longtemps habituée à assimiler les théories d'autres disciplines scientifiques. Le modèle de l'autogestion fournit un concept complexe qui donnera aux sciences de l'éducation matière à réflexion sur le phénomène de l'école. Une analyse des systèmes à la lumière de la théorie différentielle soutenue par ce modèle peut donner une vision plus claire des possibilités et des limites d'un système social moderne, comme l'est l'école aujourd'hui. Dans l'optique de ce modèle, des réponses peuvent être apportées aux questions si l'école peut remplir un rôle compensatoire par rapport au système familial, et si l'enseignement constitue aussi une action thérapeutique.

Normative Support for Improving Undergraduate Education in Teaching-Oriented Colleges

A number of recommendations to improve undergraduate education have been put forth in the higher education literature. However, we maintain that the implementation of these recommendations at our colleges and universities is unlikely if norms or group standards of appropriate and inappropriate behavior do not support these recommendations. Consequently, this study investigated the normative support for 6 selected recommendations to improve undergraduate education at teaching-oriented colleges. Results indicate support for 3 of the 6 recommendations: systematic program of advisement, providing students with prompt, formative feedback on assignments, and fostering an egalitarian classroom climate. These are the same recommendations supported by norms at higher education institutions that are more focused toward research and graduate education. The implications suggest that the normative structure that supports teaching improvement efforts may be more similar among various institutions than previous research might have indicated.     

New Contents for New Media: Pavia Project Physics

This hypermedial project deals with a historical and conceptual approach to physics. The core of the project is a certain number of case studies, namely problems or phenomena recounted together with their different interpretations. All case studies present two levels of investigation: the first level is devoted to high school students, the second level is devoted to university students and high school teachers. Our project is directed at a new and better understanding and appreciation of scientific culture.Our methodology is a historical methodology: teaching physics and the history of physics are fellow-subjects. We are not interested in adding the history of physics to teaching physics, as an optional subject: the history of physics is inside physics.Since textbooks usually give one and only one explanation of each physical phenomenon – the true explanation – we would like, on the contrary, to present the phenomena together with different interpretations that factually occurred in the history of physics. We offer four different approaches to the subject of the case study: A. Phenomena, B. Textbooks, C. History and D. Maps.The basic unit of the hypermedia is the presentation , namely a coherent set of information endowed with a definite and complete meaning. From the media point of view, a presentation consists of pictures and/or animations, key-words and/or key-sentences and a speaker explanation. Each approach consists of a certain number of presentations.     

Minority workers or minority human beings? A European dilemma

European identities may be politonymic, toponymic, ethnomyic or linguonymic (Bromley 1984). Each dimension may affect whether migrant minorities are treated as European, and influence their schooling, integration and rights. Treatment and terminology vary in different states and periods of migration. However, the position for immigrated minorities is that they are still largely seen as workers rather than human beings with equal rights. Lack of success in schools is blamed on the migrants themselves rather than the educational system. This construction of migrants as being deficient is parallel to educational practice which falls within a UN definition of linguistic genocide, and contributes to mis-education. If current efforts in international bodies to codify educational linguistic human rights were to lead to greater support for minorities, this could assist in a redefinition of national identities and a reduction of racism and conflict.

Zusammenfassung Europäische Identitäten können politonym, toponym, ethnonym oder linguonym sein (Bromely 1984). Jede Gruppe kann darauf Einfluß haben, ob Migrantenminderheiten als Europäer behandelt werden und Schulwesen, Integration und Rechte respektiert werden. Noch werden immigrierte Minderheiten jedoch weitgehend als Arbeiter und nicht als Menschen mit gleichen Rechten angesehen. Schulische Mißerfolge werden eher ihnen selbst als dem Bildungssystem angelastet. Diese Darstellung von Migranten als defizitär entspricht derjenigen Handlungsweise im Bildungsbereich, welche unter die Kategorie des linguistischen Genozids definiert wird und welche zu einer mis-education beiträgt. Wenn gegenwärtige Bemühungen internationaler Gremien um die Kodifizierung der Rechte der Menschen auf ihre Sprache Minderheiten unterstützen, könnte dies zu einer Umdefinition nationaler Identitäten und einer Reduzierung von Rassismus und Konflikten führen.

Resumen Las identidades de los Europeos pueden ser politonímicas, toponímicas, etnomímicas o linguonímicas (Bromley 1984). Cada una de estas dimensiones puede influir en que minorías de inmigrantes scan tratadas de Europeos y con ello en su educación escolar, en su integración y en sus derechos. El tratamiento y la terminología varían conforme a los períodos y las circunstancias de la inmigración. No obstante, la posición que se adopta frente a las minorías inmigrantes es la de considerarlos en gran medida como trabajadores y no tanto como seres humanos de iguales derechos. La falta de éxito en los estudios se atribuye a los inmigrantes mismos, más que al sistema de educación. Esta consideración de los inmigrantes como inferiores es paralela a una práctica de la educación que cae bajo una definición de la Naciones Unidas de genocidio lingüístico y contribuye a la educación deficiente. Si los esfuerzos actuales que las organizaciones internacionales ponen en codificar los derechos humanos lingüísticos de la educación estuvieran destinados a brindar un mayor apoyo a las minorías, esto podría ayudar a definir con mayor precisión las identidades nacionales y a reducir el racismo y los conflictos.

Résumé Les identités européennes peuvent être politonymiques, toponymiques, ethnonymiques ou linguonymiques (Bromley 1984). Selon leurs affinités avec chacun de ces domaines, les personnes appartenant aux minorités migrantes sont considérées ou non comme européennes, et cela influence leur scolarité, leur intégration et leurs droits. La façon dont ces personnes sont traitées et la terminologie évoluent selon les différentes étapes et périodes de migration. Mais le plus souvent, les minorités immigrantes sont encore davantage considérées comme des travailleurs que comme des personnes bénéficiant des mêmes droits. Les échecs scolaires sont mis sur le compte des migrants eux-mêmes et non sur celui du système éducatif. Le fait que l'on considère les migrants comme inférieurs se reflète dans une pratique éducative que les Nations Unies appellent génocide linguistique et se traduit par une éducation inadéquate. Si les efforts actuels de la part des institutions internationales pour codifier les droits de l'homme en matière de pédagogie linguistique apportaient un plus grand soutien aux minorités, cela contribuerait à donner une rédéfinition des identités nationales et à réduire le racisme et les conflits.

The relationship between psychological identification with instructors and student ratings of college courses

Drawing upon Freud's seminal discussion of psychological identification vis-a-vis group psychodynamics, this study investigated the relationship between degree of student identification with an instructor and students' ratings of instructional effectiveness. Specifically, it was hypothesized that students who highly identify with their instructor will rate the course more favorably, perceive greater progress on their part toward course related objectives, and report higher motivation to learn than students who do not identify with their instructor. Using a 50 item personality trait Q-sample, 96 undergraduates from eight different courses taught by three different instructors were asked to describe the instructor, their actual self, and their ideal self; Q-sorts for the instructor and ideal self were correlated separately for each student as the measure of identification. Instructional effectiveness was assessed using the Kansas State IDEA form. Correlational and path analyses of the data provided support for the hypothesis. Results are discussed in light of the unique contribution made by the traditional notion of identification to instructional outcomes and evaluation.     

Whitehead and a new look at teaching elementary science

If Whitehead is right, science teachers who try to increase student interest by making the science they teach more pure and by covering more material are going about their work in just the wrong way. Science, for purposes of precision in measurement, translates the dynamic world of feeling and force, of causal efficacy (for example, the San Francisco earthquake), into a static representation spatialized and given presentational immediacy (for example, the Richter scale). But notice that the Richter scale isn't very interesting (even as abstract art) apart from its connection, via symbolic reference, to the earthquake. Such reference is essential to give both a sense of reality and a feeling of interes to the subject, but it makes the science less pure, and it takes more time to cover the material. An example of teaching pure and impure formal logic is given as a case study.     

Language in education: Minorities and multilingualism in India

The question of education in India cannot be properly discussed without referring to its socio-linguistic context. This paper provides background information on the linguistic profile of India. The term minorities in the Indian context is defined, and the protection offered to linguistic minorities in the Indian Constitution is examined. A discussion of language policy in Indian education follows in which the recommendations of the different education commissions are analysed. The important issues covered include: the number of languages that are taught, the medium of instruction, and the educational policies regarding speakers of minority languages. The article also discusses different language movements and their impact on Indian education.

Three-dimensional symmetry

The errors made when high-school students locate reflections in horizontal, vertical or slanting mirrors were examined. A questionnaire consisting of thirty-six perspective drawings, each portraying an upright transparent cube containing a two-sided mirror, was given to 394 Australian students from grades 7, 9 and 11. On a corner, an edge, or a face of each cube was drawn either a point or a straight-line segment. The task was to draw its image (reflection). Analysis of errors revealed a strong tendency towards horizontal or vertical sliding, suggesting that the edges of the cube act in much the same way as a horizontal-vertical background grid does in the two-dimensional case.     

American college students' perceptions of counsellor approachability: Professional implications

The Repertory Grid technique was used to explore differences in the way in which freshers and postgraduate counselling students perceived the roles of counsellor and friend. Postgraduates viewed counsellors as more approachable than other students, while freshers viewed other students as more approachable than counsellors. The constructs identified by the students were content-analyzed to define approachability for each group. The perceptions held by students were used to address implications for the provision of outreach services, role-induction programmes, and the status of the counsellor as the professional.Department of Counseling and Educational Psychology, New Mexico State UniversityFor information contact Peggy Kaczmarek, Ph.D., New Mexico State University, Box 3CEP, Las Cruces, New Mexico 88003, United States.
