Elementary Applications of Information Theory in Various Fields of Science and Technology

Summaries

English

The concept of information is fundamental to many branches of science, technology and mathematics. A systematic use of the information concept can help to bridge the gap between different subjects in school. The discovery that information can be made a metric concept, and thus be dealt with mathematically, is fundamental to mathematics teaching. The information concept can initially be introduced on a very elementary level and then be successively exactified. From the point of view of science, information theory leads to some surprising insights into the information content of physical, chemical, biological, and technical systems.     

Teacher‐Learner Interaction in the Process of Operating DL (Distance Learning) Systems

Abstracts

English: The analysing of students’ achievements shows a significant gap between schools in different areas. One of the main factors which influenced the students’ achievement is the level of teaching. The Distance Learning System can help in bridging the gap between what is needed and what the school can supply today     

A customised Total Quality Management Framework for schools

Abstract

Research has revealed that many of the historically disadvantaged schools in South Africa experience difficulty in implementing policies aimed at restoring the quality of teaching and learning. The difficulty has been attributed to several factors such as poor conceptualisation and implementation of quality management systems at school level. This article reports on empirical research that investigated the possibility of applying Total Quality Management principles in schools for the purpose of restoring the culture of learning and teaching. Data was collected through qualitative and quantitative methods in selected schools situated in the Tshwane North District. The findings revealed that there is a gap between what is provided in the policy framework on the management of quality teaching and learning. It is recommended that in order to fill the gap, schools need to apply customised principles of Total Quality Management. The primary aim of this research was to develop such an integrated framework that is not only theoretically sound but that has been customised for schools’ contexts and conditions.     

Education as a Moral Practice

The interest in moral education has focused largely on the teaching of morality or on nurturing moral qualities and virtues or on the "moral atmosphere" of the school; but little, comparatively speaking, has been written about education itself as essentially a moral practice. Failure, in this respect, has damaging results. First, the practice of education goes adrift from its moral roots — and serves particular ends such as economic well-being or citizenship as conceived by those in power. Secondly, the programmes of moral or personal and social education are isolated from the moral context in which they make sense. These issues are addressed in the lecture.     

The use of modern standard and spoken Arabic in mathematics lessons: the case of a diglossic language / El uso del árabe estándar moderno y del árabe hablado en las clases de matemáticas: el caso de una lengua diglósica

Abstract

Researchers have shown an increased interest in the way teachers use their knowledge about language (KAL) to enhance student understanding and learning. This qualitative case study investigated first- and second-grade teachers’ use of KAL in Arabic. We investigated the linguistic transitions from standard Arabic to spoken Arabic made by the teachers during mathematics lessons. The results suggested that Arab-speaking mathematics teachers were aware of the gap between home language (Spoken Arabic) and school language (Modern Standard Arabic) and used linguistic transition as a teaching strategy to develop academic thinking and behaviour among their students. The results suggested that Arab teachers built a non-formal bilingual education programme where the two languages were used to teach mathematics. Despite the requirement to use Modern Standard Arabic, participants bridged the gap between the languages, which suggests an inherent understanding that ‘language and identity are ultimately inseparable’.     

Effects of 6E-oriented STEM practical activities in cultivating middle school students’ attitudes toward technology and technological inquiry ability

ABSTRACT

Background: STEM education has become a focus of research and teaching interest in recent years. However, not all scholars agree on the definition and purpose of STEM education. This paper summarizes related past research and suggests that, according to the requirements of Taiwan’s educational environment, STEM education should focus on the cultivation of middle school students’ attitudes toward technology and their ability to engage with technological inquiry.

Purpose: The purpose of this study is to explore the effects of STEM education on attitudes toward technology and technological inquiry abilities of middle school students, this study used the 6E Learning byDeSIGN? model proposed by the International Technology and Engineering Educators Association in the US to design a 6E-oriented STEM practical activity.

Sample: The sample of the study consisted of 139 seventh-grade students from six different classes who participated in a practical activity related to egg protection devices.

Design and methods: To achieve this research purpose, a quasi-experimental design was used, with pre-treatment and post-treatment evaluations of each group. Both the experimental and control groups participated in the activity; however, the experimental group students were guided through the activity using a 6E teaching strategy, whereas the control group students were guided using a problem-solving teaching strategy.

Results: The results showed that a 6E teaching strategy had a positive effect on middle school students’ attitudes toward technology and technological inquiry abilities, but these effects were not statistically different from the effect on the control group with problem-solving teaching strategy.

Conclusions: This study indicates there is no significant advantage in using a 6E process over a problem solving approach. Technology teachers aiming to improve students’ attitudes toward technology and their technological inquiry abilities consider refining the 6E-oriented STEM practical activity process, and students may demonstrate better performance in these two areas.     

High school students’ approaches to learning physics with relationship to epistemic views on physics and conceptions of learning physics

Background and purpose : Knowing how students learn physics is a central goal of physics education. The major purpose of this study is to examine the strength of the predictive power of students’ epistemic views and conceptions of learning in terms of their approaches to learning in physics. Sample, design and method : A total of 279 Taiwanese high school students ranging from 15 to 18?years old participated in this study. Three questionnaires for assessing high school students’ epistemic views on physics, conceptions of learning physics and approaches to learning physics were developed. Step-wise regression was performed to examine the predictive power of epistemic views on physics and conceptions of learning physics in terms of their approaches to learning physics. Results and conclusion: The results indicated that, in general, compared to epistemic views on physics, conceptions of learning physics are more powerful in predicting students’ approaches to learning physics in light of the regression models. That is, students’ beliefs about learning, compared with their beliefs about knowledge, may be more associated with their learning approaches. Moreover, this study revealed that the higher-level conceptions of learning physics such as ‘Seeing in a new way’ were more likely to be positively correlated with the deep approaches to learning physics, whereas the lower-level conceptions such as ‘Testing’ were more likely to positively explain the surface approaches, as well as to negatively predict the deep approaches to learning physics.     

Developing collaborative approaches to enhance the professional development of primary mathematics teachers

This research project promoted a collaborative model of professional development between lead teachers from three schools, supported by a project coordinator and a researcher from a local university. Each lead teacher worked with their head teacher to design, lead, and evaluate an innovative, personalised, and school-based mathematics continuing professional development (CPD) programme in their school. University staff helped to facilitate project meetings across the schools and monitored impacts within each school. Professional development meetings, involving all teachers and teaching assistants (TAs) from the schools (n?=?55), were designed to encourage a whole-school approach. The project also provided structured opportunities for the lead teacher to work with colleagues in the classroom, for example, through lesson observation and/or collaborative teaching. The outcomes from this project confirmed that collaborative models of CPD, as opposed to transmission, formal training, and ‘top-down’ models, were welcomed by teachers and head teachers – some of whom reported early indications of improvements in student performance. Commenting on what constitutes the most effective forms of CPD, there was a reiteration of the importance of combining peer and external support through a collaborative process.     

The Promise of Restorative Practices to Transform Teacher-Student Relationships and Achieve Equity in School Discipline

ABSTRACT

Restorative approaches to school discipline are increasingly being implemented throughout the United States in an attempt to reduce reliance on suspension and eradicate the racial discipline gap. Yet, little is known about the experience of students in classrooms utilizing restorative practices (RP). This study draws on student surveys (N = 412) in 29 high school classrooms. Hierarchical linear modeling and regression analyses show that high RP-implementing teachers had more positive relationships with their diverse students. Students perceived them as more respectful and they issued fewer exclusionary discipline referrals compared with low RP implementers. In addition, the findings demonstrate some initial promise of well-implemented RP for narrowing the racial discipline gap. The study found that higher RP implementers issued fewer discipline referrals to Latino and African American students compared with lower RP implementers. The study findings have implications for equity-focused consultation in schools that honor student experience of new programming.     

What about research and evidence? Teachers’ perceptions and uses of education research to inform STEM teaching

Abstract

The use of research evidence to inform practice has become an expectation of those working in many professions. There is a dearth of research on teacher use of scholarship to inform their practice. While there is an abundance of research that can be used to inform teacher practice, there are unknowns about how much teachers seek, access, read, apply and share evidence from research to inform their teaching. We address this gap in the literature by surveying inservice teachers about their perceptions and practices for using education research. In our analysis of the data collected from 452 teachers, we found teachers are interested in research and perceive value in research to inform their work. However, we also found that teachers struggle to identify sources of quality research and how to translate research to inform their teaching. Our findings have implications for school administrators seeking to promote teacher engagement in evidence-based practice and educational researchers hoping to have their research translated into K-12 teacher practice.     

BOOK REVIEW

This paper presents the results of a long-term project which compared primary school student-teachers' theories on teaching with their actual teaching, investigated the factors underlying the revealed discrepancy and tried to explain it. The results indicated that although student-teachers' educational views shifted in their final year of study towards a child-centred and constructivist view of teaching, this was not implemented in their actual teaching. Analysis of videotaped lessons and interviews with student-teachers revealed some grave misconceptions about teaching and learning. The paper argues that these misconceptions were the principal factor underlying the mismatch that was identified between student-teachers' theories on teaching and their actual teaching. The hypothesis is also put forth that these misconceptions are likely the result of deeply embedded cultural values through which student-teachers' understanding of the new pedagogical approaches is mediated.     

Digital game building: learning in a participatory culture

Background: Research findings indicate that developing good relationships with pupils, managing classroom processes adequately and developing confidence and trust with other teachers are among the aspects of teaching that are found to be challenging. Although many studies conclude that collaborative reflection is a crucial activity for supporting teachers’ professional development in school, studies that focus on what teachers reflect on and how they reflect are more limited.

Purpose: The purpose of the study was to improve our understanding of what situations teachers experience as challenging in their teaching, what types of help they seek when trying to manage such situations and, furthermore, how teachers reflect together on how to develop as teachers, when they have time to collaborate.

Sources of information and method: The study aimed to explore these areas theoretically by bringing together data from, and discussing the implications of (1) an interview study and (2) a formative intervention study which involved teachers from lower secondary schools in Norway working with a researcher–participant. The data were analysed by using the constant comparative method of analyses. By discussing aspects of these two studies together, the research aimed to identify and address some of the theoretical questions pertinent to teacher development.

Findings and conclusions: The analysis and discussion of the data from the two studies illuminates teachers’ recognition of the value of having time to reflect together. It also indicates, however, that it is not only a matter of teachers having time to observe, reflect together and focus on their development processes: the types of discourse used during collaborative reflection must also be suitable. The researcher–participant’s role highlighted the untapped potential to be found by looking into how language is used in dialogues aimed at supporting teacher development. Helping teachers to develop the skills to reflect collaboratively and constructively, in a way that ultimately improves teaching and learning, is therefore an important challenge for teacher education and the education of teachers and school leaders.     

Science and Technology in the Classroom

summaries

English

In Britain, the range of new resources developed in the 1960s and early 70s for science teaching in secondary schools have achieved considerable success. However, there are still widespread criticisms by both students and teachers that school science curricula tend to be inward‐looking, divorced from human considerations and unrelated to the influences of technology. Evidence that attitudes to technology among secondary school teachers may be changing is provided by the existence of three new projects; two covering the 13‐16 age range and one the 16‐18. The three projects, although organized quite differently, have much in common. Thus each is developing new kinds of teaching materials which take into account not only the applications of science but also economic, social, ethical and aesthetic considerations as well. The introduction of these new resources will require teaching approaches some of which are at present unfamiliar to many students and some teachers. The development of technology in an educational context could well become a feature of the science curricula of our secondary schools in the 1980s.     

Using an adaptive expertise lens to understand the quality of teachers’ classroom implementation of computer-supported complex systems curricula in high school science

Background: This exploratory study is part of a larger-scale research project aimed at building theoretical and practical knowledge of complex systems in students and teachers with the goal of improving high school biology learning through professional development and a classroom intervention.

Purpose: We propose a model of adaptive expertise to better understand teachers’ classroom practices as they attempt to navigate myriad variables in the implementation of biology units that include working with computer simulations, and learning about and teaching through complex systems ideas.

Sample: Research participants were three high school biology teachers, two females and one male, ranging in teaching experience from six to 16 years. Their teaching contexts also ranged in student achievement from 14–47% advanced science proficiency.

Design and methods: We used a holistic multiple case study methodology and collected data during the 2011–2012 school year. Data sources include classroom observations, teacher and student surveys, and interviews. Data analyses and trustworthiness measures were conducted through qualitative mining of data sources and triangulation of findings.

Results: We illustrate the characteristics of adaptive expertise of more or less successful teaching and learning when implementing complex systems curricula. We also demonstrate differences between case study teachers in terms of particular variables associated with adaptive expertise.

Conclusions: This research contributes to scholarship on practices and professional development needed to better support teachers to teach through a complex systems pedagogical and curricular approach.     

What can policy makers do to encourage integration of information and communications technology? evidence from the irish school system

Abstract

While most countries have invested heavily in information and communications technology (ICT) in education in recent years, the progress with integration of ICT into the teaching of other subjects has often been disappointing. How to encourage integration remains a serious question for policy makers and teacher educators. This article proposes some answers to that question, based on examination of data from the Irish school system. It suggests that ICT integration is associated with two kinds of teacher professional development: postgraduate ICT courses, and short in-service courses focused on specific integrated uses of ICT. The data reveal a strong association between the use of ICT in the school and the ICT usage of the school principal. Finally, it calls into question the use of pilot projects as the agents of change.     

Renewal of Teaching Methods in Physical Chemistry at University Level: the Assessment of a 10‐Year Experiment

Summaries

English

The author has been responsible for first and secondsemester courses in physical chemistry for more than 10 years. In one subject, which is studied by 100 to 250 students per year, he and some of his colleagues have introducedteaching methods which differ considerably from the classical ones.

Students working in small groups, the usage of prepared materials by the teaching staff, the integration of theoretical and directed teaching, the continual examinationof knowledge, the almost complete disappearance of coursestaught in a school‐masterly way have led to consequences which have had a positive influence on the relationship between the students and the teachers and on the quality of teaching.

In this article, the author presents an interim evaluation of the experiences gained in conducting the course.     

Secondary school students who drop out of school in rural Pakistan: The perspectives of fathers

ABSTRACT

Background: The problem of students dropping out of school is one of the barriers to improving educational outcomes in poor and developing countries.

Purpose: This small scale, in-depth study sought to explore the phenomenon of students who drop out from secondary education, through the perspectives of fathers of such students in a rural district of Pakistan.

Method: Primary data were collected through detailed, individual interviews with 14 fathers whose sons had dropped out from secondary education. The study adopted a framework involving push and pull factors to analyse qualitatively the processes and examine the reasons for dropping out that prevailed inside and outside school.

Findings: The analysis suggested that, from the perspectives of the fathers, family poverty, poor academic performance and issues relating to teachers’ engagement with teaching at school were main factors involved in a student dropping out of school.

Conclusions: The findings from this small scale, detailed analysis of data draw attention to the issues arising from a tension in mainstream teachers’ educational roles in and beyond the school. It further highlights the need for greater investment in secondary education, in order to help to reduce rates of student drop out in the remote rural areas of Pakistan.     

Trainee teachers’ experiences of teaching practicum: Issues,challenges, and new possibilities

Abstract

This paper focuses on a qualitative case study concerned with teaching practicum as a pivotal component of teacher education in Malawi. It addresses some of the issues and concerns associated with workload, ill-defined mentoring support, and implementation of certain pedagogical orientations during teaching practicum placement. Purposive sampling was used to select participants. Data were collected through semi-structured interviews. The findings indicate that trainee teachers undergo varied and often challenging experiences during teaching practicum. To counter some of the concerns, suggestions are made to improve certain aspects of teaching practicum. There is need for authentic school – college partnerships, improved structures of school-based professional support, and a deeper awareness of the complexity of learner-centred pedagogy. It is imperative that teacher educators engage with these findings to further improve the design of teaching practicum and the overall quality of teacher education and teaching in Malawi.
