Primary school students’ conceptions about microorganisms. Influence of theoretical and practical methodologies on learning

Background: Microorganisms are very important in day-to-day life, but they are inadequately addressed in the Spanish educational system. It is essential that students are well informed about their characteristics and functions.

Purpose: The study aims to find out primary school students’ perceptions of microorganisms and to analyze whether theoretical or practical teaching interventions produce different levels in student’s learning about this topic.

Sample: The sample consisted of 199 primary students in 2nd (aged 7–8) and 6th (11–12) grades from two public schools in Albacete (Spain).

Design and method: This study uses a pre- and post-intervention questionnaire to evaluate the knowledge of students on the issue of microorganisms. We compare differences by age and two teaching–learning intervention methodologies: theoretical and practical.

Results: Results from the pre-test showed a poor understanding and several misconceptions. Children have a limited and negative view of microorganisms, mainly derived from non-formal learning. Both types of intervention provided an improvement in knowledge, but closed questions did not reveal clear statistically significant differences between methods. Open questions showed how the scientific use of the language and quality of verbalization is much better in the groups that received a practical intervention.

Conclusion: The findings can be a starting point for curriculum planners and for teachers interested in engaging students in science learning.     

Collaborative project-based learning: an integrative science and technological education project

Background: Blending collaborative learning and project-based learning (PBL) based on Wolff (2003) design categories, students interacted in a learning environment where they developed their technology integration practices as well as their technological and collaborative skills.

Purpose: The study aims to understand how seventh grade students perceive a collaborative web-based science project in light of Wolff’s design categories. The goal of the project is to develop their technological and collaborative skills, to educate them about technology integration practices, and to provide an optimum collaborative, PBL experience.

Sample: Seventh grade students aged 12–14 (n = 15) were selected from a rural K–12 school in Turkey through purposeful sampling.

Design and methods: The current study applied proactive action research since it focused on utilizing a new way to enhance students’ technological and collaborative skills and to demonstrate technology integration into science coursework. Data were collected qualitatively through interviews, observation forms, forum archives, and website evaluation rubrics.

Results: The results found virtual spaces such as online tutorials, forums, and collaborative and communicative tools to be beneficial for collaborative PBL. The study supported Wolff’s design features for a collaborative PBL environment, applying features appropriate for a rural K–12 school setting and creating a digitally-enriched environment. As the forum could not be used as effectively as expected because of school limitations, more flexible spaces independent of time and space were needed.

Conclusions: This study’s interdisciplinary, collaborative PBL was efficient in enhancing students’ advanced technological and collaborative skills, as well as exposing them to practices for integrating technology into science. The study applied design features for a collaborative PBL environment with certain revisions.     

The effectiveness of hybrid dynamic visualisation in learning genetics in a Hong Kong secondary school

Background: A teaching method to improve students’ ability to communicate ideas in genetics across the macro–micro levels of organisation was investigated in this study.

Purpose: It is designed to help students deconstruct the level of organisation of each tier of a genetic diagram, as the symbols used in such diagrams (i.e. lines and letters) can be too abstract to serve as hints for students to identify the level of organisation.

Design and method: The method employs hybrid dynamic visualisation, which combines static (e.g. a genetic diagram) and dynamic visualisations (e.g. meiotic cell division, fertilisation). The method also addresses the learning problem wherein students isolate the conceptual components of the processes of meiotic cell division and fertilisation from the procedural components of genetic diagrams. The new pedagogy was trialled in a voluntary enrichment course with 22 Secondary Six (or 12th grade) students.

Results: The results of conceptual assessments and individual interviews show that the participating students, in general, provided more explanations at the molecular level, although there is considerable room for improvement in making a smooth macro–micro transition. Students also had a better grasp of the symbolic representation and mathematical concepts of genetics. In addition, their responses in individual interviews revealed that they shared a restricted understanding of the term ‘recessiveness’.

Conclusion: Possible scaffolds for revisiting the concept of recessiveness in regular teaching are suggested.     

The development of the nature of science view scale (NOSvs) at university level

Background: Determining individuals’ views of the nature of science is quite important for researchers since it is both a component of scientific literacy and a fundamental aim of science education.

Purpose: This study aims to develop a NOSvs for assessing prospective teachers’ views of the nature of science and to analyse their psychometric properties.

Sample: A total of 565 prospective teachers participated in the study.

Design and methods: The Kaiser–Meyer–Olkin (KMO) Index and Bartlett’s Sphericity Test were used in this study. Confirmatory factor analysis (CFA) was performed to determine the construct validity of the scale. Cronbach’s Alpha (α) coefficient was calculated for the reliability of the study.

Results: It was consequently found that the KMO was larger than .50. That Bartlett’s Sphericity Test was also statistically significant. The items with item-total correlations smaller than .30 were removed from the scale. Cronbach’s α values calculated for each sub-scale were above .70. In consequence of the first CFA performed, fit indices were found to be below the expected level. For this reason, three more items with the least item-total correlations were removed from the scale. Following the CFA, the final form of the scale included 36 items and five sub-scales.     

Infantilism

The aim of this article is to define and operationalize the construct of infantilism.

The methods of theoretical research involve analysis and synthesis. Age and content criteria are analyzed for childhood and adulthood. Infantile traits in an adult are described.

Results. The characteristics of adult infantilism in the modern world are defined, taking into account increasing information flows and socio-economic changes. The concept of “infantilism” and its main features are defined as an organization of the personality that includes traits and behavioral models that are typical of one's earlier age periods and not appropriate to the person's actual age, which is most articulately manifested in emotional and volitional immaturity of an individual.

Scientific novelty. The main psychological characteristics of adulthood are described, including reflection, the desire to work and have a vocation, vocational self-determination, work skills, the desire for self-realization, and emotional and volitional maturity. Objective characteristics of adulthood are: transition to economic and territorial independence of the parental family, and development of new social roles, such as that of worker, spouse, and parent. Two possible operationalizations of the concept are identified: objective (existence/absence in a person’s life of objective criteria of adulthood) and subjective (self-report on the subjective feeling of existence/absence of the psychological characteristics of adulthood).

The practical significance of the work consists in formulation of an operationalization of “infantilism,” which at the moment has so many interpretations. Such operationalization is necessary for further analysis and research.     

The effect of concept cartoon-embedded worksheets on grade 9 students’ conceptual understanding of Newton’s Laws of Motion

Background: A substantial review study of concept cartoons reports that few studies have indicated their functions. For this reason, the present study illuminates the extent to which concept cartoon-embedded worksheets (through constructivist context) accomplish these functions in conceptual learning.

Purpose: The purpose of the study is to determine the effect of the concept cartoon-embedded worksheets on grade 9 students’ conceptual understanding of Newton’s Laws of Motion.

Sample: Within a quasi-experimental research design with control group, the sample consisted of 102 grade 9 students (aged 15–16 years) enrolled in an Anatolian High School. They were randomly assigned to control (52 students) and experimental groups (50 students).

Design and methods: While the control group followed the existing physics instruction, the experimental one was exposed to the concept cartoon-embedded worksheets. To collect data, two scales (Newton’s Laws of Motion Test –NLMT– and Interview about Instances –IAI) were employed.

Results: The results indicated that the experimental group performed better than did the control group.

Conclusions: It can be deduced that the concept cartoon-embedded worksheets are effective in improving grade 9 students’ conceptual understanding and in replacing their alternative conceptions with scientific ones.     

How teaching practices are connected to student intention to enrol in upper secondary school physics courses

Background: In developed countries, it is challenging for teachers to select pedagogical practices that encourage students to enrol in science and technology courses in upper secondary school.

Purpose: Aiming to understand the enrolment dynamics, this study analyses sample-based data from Finland’s National Assessment in Science to determine whether pedagogical approaches influence student intention to enrol in upper secondary school physics courses.

Sample: This study examined a clustered sample of 2949 Finnish students in the final year of comprehensive school (15–16 years old).

Methods: Through explorative factor analysis, we extracted several variables that were expected to influence student intention to enrol in physics courses. We applied partial correlation to determine the underlying interdependencies of the variables.

Results: The analysis revealed that the main predictor of enrolment in upper secondary school physics courses is whether students feel that physics is important. Although statistically significant, partial correlations between variables were rather small. However, the analysis of partial correlations revealed that pedagogical practices influence inquiry and attitudinal factors. Pedagogical practices that emphasise science experimentation and the social construction of knowledge had the strongest influence.

Conclusions: The research implies that to increase student enrolment in physics courses, the way students interpret the subject’s importance needs to be addressed, which can be done by the pedagogical practices of discussion, teacher demonstrations, and practical work.     

Mirror Neurons,The Development Of Empathy,And Digital Story Telling

This article explores the intersection of work in media education, religious education, concerns about digital cultures’ impact on human relationality, and the possible role that mirror neurons might play in the development of empathy. Digital story telling—particularly as embodied in the work of the Center for Digital Storytelling (http://www.storycenter.org), and the Storytelling as Faith Formation project (www.storyingfaith.org)—is proposed as a mechanism within which to foster mirror neuron development, and thereby provide one promising route for deepening empathic learning within religious education.     

University students’ meta-modelling knowledge

Background: As one part of scientific meta-knowledge, students’ meta-modelling knowledge should be promoted on different educational levels such as primary school, secondary school and university. This study focuses on the assessment of university students’ meta-modelling knowledge using a paper–pencil questionnaire.

Purpose: The general purpose of this study was to assess and to describe university students’ meta-modelling knowledge. More specifically, it was analysed to what extent the meta-modelling knowledge, as expressed in a questionnaire, depends on the scientific discipline to which university students relate their answer and the concrete model to which they refer while answering.

Sample: N = 184 students from one German university voluntarily participated in this study.

Design and methods: The questionnaire was developed based on a theoretical framework for model competence and includes constructed response items asking about the purpose of models, ways for testing models and reasons for changing models. Students written answers were first analysed qualitatively based on the theoretical framework to decide whether they expressed advanced understandings or not. Further analyses then were conducted quantitatively.

Results: Findings suggest that only few university students possess an advanced meta-modelling knowledge. However, significant more students who relate their answers to the STEM-disciplines expressed advanced understandings than those who referred to social sciences or linguistics/philology. Furthermore, university students who expressed an advanced meta-modelling knowledge referred to rather abstract kinds of models in order to explain their view.

Conclusions: The present study supports the assumption that meta-modelling knowledge may be situated and contextualised. Both the scientific discipline and the concrete model to which university students refer seem to be relevant item features influencing university students’ expressed meta-modelling knowledge. Implications for assessment and teaching are discussed in the article.     

Steps to promote open and authentic dialogue between teachers and school management

Purpose: School principals must determine educational policies and make information-based decisions. Teachers have authentic information that they do not transmit in full to the principals. A theoretical model was tested that explains the factors behind this disconnection in communication.

Design: Four hundred and forty-five teachers completed questionnaires that examined a variety of aspects of reciprocal relations between teachers and school management.

Findings: The model explains 44% of the variance in authentic teacher–principal communication. The principal’s communication pattern with teachers, with two sub-components, represents a dominant factor in teacher willingness to share information. Leadership style represents only an indirect factor.     

Cognitive Style and Problem Behaviour in Boys Referred to Residential Special Schools

The paper considers aberrant behaviour in the context of cognitive style with reference to both diagnosis and treatment.

Aims.

The aims of the study were to investigate whether the style of pupils with behaviour problems was different from that of children with no reported problems, and also to consider how pupils of different style manifested their problem behaviours.

Sample.

The sample comprised 83 male pupils aged 10‐18 years from two residential special schools.

Method.

The sample were given the Cognitive Styles Analysis to assess their positions on the Wholist‐Analytic and Verbal‐Imagery style dimensions. The pupil records of the special school pupils who were at the extreme of the style dimensions were also examined.

Results.

When their style characteristics were contrasted with a Comparison Sample of 413 12‐16‐year‐old males attending 10 secondary schools, the special school pupils had a significantly higher proportion of both Wholists and Verbalisers, than the Comparison Group. Further, the inspection of the records indicated that the types of social behaviour and behaviour problems exhibited varied with style, and particularly on the Wholist‐Analytic dimension.

Conclusion.

The results were considered to have implications for the origins and treatment of problem behaviour.     

Teaching global climate change to pre-service middle school teachers through inquiry activities

Background Global climate change (GCC) has become one of the most debated socio-scientific issues after an increase in media attention. Recently, there have also been several studies describing students’ and teachers’ alternative conceptions about GCC. Therefore, designing learning environments at the college level that focus on accurate conceptions of GCC has become important in order for pre-service teachers to correct their alternative conceptions. There are, however, a limited number of studies that aim to both increase pre-service teachers’ knowledge about these issues and explore their perceptions of teaching this subject.

Purpose The purpose of this study was to investigate the effects of inquiry-based activities on pre-service teachers’ knowledge about GCC and their perceptions of teaching this subject.

Sample The participants were 102 pre-service middle school mathematics and science teachers who were enrolled in an environmental education course.

Design and methods A one group pre-test–post-test design was employed to identify changes after pre-service teachers engaged in a learning unit on GCC. The inquiry-based GCC unit was implemented during the spring semester at a public university in northeastern Turkey. The unit was implemented over seven sessions. Data were collected through two questionnaires: the ‘GCC content questionnaire’ and the ‘perceptions of teaching GCC questionnaire’. Each questionnaire was administered both before and after implementation of the unit. Content questionnaire responses were analyzed using a paired-samples t-test. Responses to the perceptions of teaching questionnaire were analyzed using inductive open coding.

Results Results indicated that after the implementation the pre-service teachers significantly improved their understanding of GCC across all items in the content questionnaire, saw several benefits of and challenges about teaching GCC, and perceived themselves as better prepared to teach about GCC in their future classrooms.

Conclusions Teacher education programs should integrate inquiry-based GCC instruction to increase pre-service teachers’ knowledge as well as their preparedness to teach about this important planetary issue.
