Authors: Olsson A. .
Published: March 2020

Lung cancer is the most common cancer globally, with more than 2 million new cases per year. It is also the cancer that causes most deaths, i.e. about 1.7 million annually or 18% of all cancer deaths. In the Russian Federation, lung cancer is the most common cancer among men, while still relatively rare among women. In Northern and Western Europe, lung cancer rates in men have decreased in the last 20 years, while the rates in women keep rising. These global patterns are largely influenced by the national smoking prevalence in the previous decades for respective sex. Environmental and occupational risk factors also contribute to the burden of lung cancer, but the extent of this contribution varies over time and by location. There is a large potential for preventing lung cancer development by reducing and eliminating external risk factors.

Job satisfaction and turnover intention among public sector nurses: Is workload and burnout the issue?
Authors: Dwinijanti Lenny , Adhikara M. F. Arrozi , Kusumapradja Rokiah
Published: March 2020

The growing rate of nurse turnover is unavoidable and inevitable. Nursing considered one of the most stressful occupations in the health industry. Unfortunately, there are limited studies published in Indonesia that explain this phenomenon among clinical nurses. This study aims to describe the nurse job satisfaction and turnover intention at public hospitals from workloads and burnout perspective. The design used in this study was quantitative with the survey approach. The data were collected by using simple random sampling from the hospital (cluster B) nurses with the total participant was 190 nurses. The result of this study shows that workload and burnout affect job satisfaction directly. The mediator role of job satisfaction in the effect of workload and burnout on turnover intention is significantly proved. Interestingly, this study failed to prove the effect of workload on turnover intention which means that although many nurses experienced a heavy workload, the majority of nurses in this study feel that the workloads are still reachable or even low due to their young aged. They tend to keep the job since it’s difficult to find any other opportunities. They will intend to leave their job only if they experienced a greater level of burnout and disenchantment.

Molecular gastronomy in science and cross-curricular education – The case of “Kitchen stories”
Authors: Fooladi Erik
Published: March 2020

The recent years have seen an increased interest in science education aimed towards the nature of science and inquiry. Within this context, promotion of reasoning and argumentation in school science has come forth as an important field of research. The present contribution describes the project “Kitchen stories” which seeks to develop a framework for teaching argumentation and inquiry in a cross-curricular setting comprising science and home economics. The explicit teaching of Toulmin’s argumentation pattern is utilised for students to analyse claims, expand them to build complete arguments and plan open-ended inquiry with regards to specifications (i.e. claims) about food and cooking collected from authentic sources in everyday life, herein termed “culinary precisions”. This way a holistic teaching framework has been constructed incorporating project work, argumentation, inquiry, second-hand investigations, sourcing skills and declarative knowledge. Preliminary results from the study involving pre-service teacher students in science and home economics are described. Possibilities, challenges and prospects are discussed when using kitchen stories for teaching argumentation, inquiry and other pertinent topics in science education.
Delicious mincemeat sauce and studying fried onion with an FTIR spectrometer
Authors: Hämäläinen Eila
Published: March 2020

My students at the upper secondary school chemistry course have prepared mincemeat sauce and sweet potato mash as a study project for two consecutive years. Half of the students prepared the dish using traditional methods and the other half using molecular gastronomy. At the end of the class we tasted the dishes prepared with different methods and compared them against each other. During cooking, we studied how onion’s large carbohydrates break down to smaller sweet sugars when heated on a low temperature. This sweetening can also be tasted because small molecule carbohydrates are water-soluble and fit in the mouth taste receptors. A sample was taken off the pan once every five minutes and extracted to water. IR spectra were run from the onion-water extract and the received spectra were compared to library sources and references. The aim was not to conduct a thorough analysis of the components formed during cooking, instead the spectra were analysed for indications on whether or not the amount of sugar (sweetness) increases as a function of cooking time. The performed work indicated with sufficient accuracy that sucrose was formed during cooking up to 35 minutes of cooking time, after which the product started to show possible signs of caramelisation and Maillard reaction, and the amount of sugars dropped. The method requires further development in order to find out the ratio of sucrose and glucose formed during heating as compared to their concentration in a raw onion. Preparing (heating) the samples and extracting the sample still require further development in order to present the formation of sugar during heating unambiguously.

Authors: Uitto Anna , Kärnä Pirkko , Hakonen Riikka
Published: March 2020

The contribution of different working methods and learning environments to grade nine students’ performance in biology as well as their attitudes towards biology as school subject were studied. The research is based on the data collected for the assessment in natural sciences at comprehensive schools by the Finnish Board of Education in 2011. The survey data of the present study consisted of 2989 ninth grade students from 97 comprehensive schools. Students’ performance in biology was clearly correlated with the positive attitude towards biology as a school subject. There were strong correlations between the performance and teaching approaches, which emphasize students’ activity in experimental investigations, making observations, pondering of causes and effects as well as applying knowledge to everyday live. These inquiry-oriented approaches correlated also with the positive attitude towards biology. There were also correlations between positive attitude to biology and teacher-led conversations, pondering of different viewpoints, taking account of students’ opinions and ideas in teaching and the methods emphasizing students’ autonomy and self-evaluation. Positive attitude correlated also with the teaching approach, by which students received information about the development, structures and mechanisms of the world. Directed teaching did not correlate with the performance in biology or the positive attitude towards biology. To enhance students’ performance and positive attitudes in biology, it would be important use experimental work and inquiry-based learning in biology education.

Comprehensive evaluation offers inspiration and achievement in chemistry education
Authors: Ojala Päivi
Published: March 2020

Practical laboratory activities have become more common in primary and secondary education with the current curriculum. In lower secondary school, laboratory work in chemistry and physics has been used even longer. The central issues of laboratory work becoming more common are how the activities are organized, safety of the laboratory work, and evaluation. Laboratory work has been taken into account in evaluation in many different ways, for example, a written assignment has been complemented with a practical assignment. The evaluation method provides those who can practically and manually demonstrate activeness and skill with the possibility to succeed.
Societal view on chemistry teaching, food as example
Authors: Tolppanen Sakari , Aksela Maija
Published: March 2020

It is important to link societal issues to teaching in order to achieve all-round education and scientific literacy linked to it. The prerequisite for successful sustainable development education is that the themes of sustainable development are studied diversely from the perspectives of the environment, society, and economy. This article studies how the three aspects of sustainable development could be implemented in teaching through a food theme. The subject is approached with the help of recent examples from the media.

Welcome to the final issue of the first volume of LUMAT. With two regular issues, three special issues, eleven research articles, two perspective articles and thirty general articles published, the first volume of LUMAT has been a success. With three special issues and two regular issues lined up for the second volume, we hope to continue publishing quality articles on research and practice in math, science and technology education.

The purpose of the journal is to share good practices, and present especially Finnish but also international know-how in the field of math, science and technology education. With this purpose in mind, it has been a pleasure to publish several manuscripts from our colleagues around the globe. Also this final issue of the first volume includes articles from Finnish as well as international educational researchers.

The first article, by Jeronen, Karjalainen, Kuoppala, Sääskilahti and Tirri discusses the new student admission process of subject teacher education. Their topic is especially interesting, as the coming years are about to bring changes to student admission processes of Finnish universities.

The second article is a product of an international collaboration with Finnish and North American researchers. The study by Tolppanen, Rantaniitty, McDermott, Aksela and Hand investigates how Finnish comprehensive school students received a multimodal writing lesson. They conclude that general writing skills benefit students in production of multimodal writing during science lessons.

The last study published in this issue discusses the use of classroom response systems (also known as clickers) in physics teacher education. According to the results of the North American researchers Milner-Bolotin, Fisher and MacDonald clicker-enhanced pedagogy is a promising vehicle for developing pedagogical content knowledge of science teachers. The results of this study are interesting also from a Finnish perspective, as also Finnish teacher educators are searching new ways to implement use of modern educational technology to science and mathematics teacher education.

Matematiikan kuusi osaa: David Tallin matematiikan kolmen maailman viitekehyksen laajentaminen Juha Oikkosen matematiikan kaksilla kasvoilla
Authors: Hannula Jani
Published: March 2020

The three worlds of mathematics by David Tall provide a framework for studying mathematical thinking and its development. Extending the framework of three worlds by Tall with Juha Oikkonen’s ”two faces of mathematics” develops a new, broader framework in which certain aspects to research on learning mathematics (such as mini-theories) are included to form a larger entity. The framework, previously drafted by Oikkonen and more thoroughly analyzed in this article, has the power to explain, for example, the learning processes of individual mathematical concepts.

Abstract
Solar Cells Based on Light-absorbing Dyes and Perovskites
Authors: Rendon Sabine
Published: March 2020

The first solar cell was invented nearly two centuries ago, but during the recent years the progress has been rapid. In addition to the well known silicon soler cells, there is now a large number of other solar cells. These solar cells have many interesting properties, such as the the color, design and manufacturing processes. This paper discusses the solar cells based on light-absorbing dyes and perovskites.
Workshop: iPads in Upper Secondary School Chemistry Education
Authors: Nikula Antti
Published: March 2020

At the workshop arranged at the National Days of Chemical Education the participants had an opportunity to try out various Ipad apps and methods for utilizing them in chemistry education. The themes were based on the apps used during chemistry teacher education course arranged by the department of chemistry and methods developed on the teacher training school at the University of Jyväskylä. The apps used included Socrative Student, Google Drive, Graphical Analysis, ChemDoodle ja QR-reader. Out of these Socratice, which collects students answers to questions created by the teacher, was considered easy-to-use and the most useful by the participants. The participants also felt, that the workshop had improved their image of IPads as learning tools.

In-Service Teacher Training Project On Inquiry-Based Practical Chemistry
Authors: Tomperi Päivi , Aksela Maija
Published: March 2020

The aim of study is to support meaningful practical chemistry learning and research-based teaching at the upper secondary level by designing a model for in-service teacher training. Teachers were introduced the SOLO (= Structure of the Observed Learning Outcome) taxonomy as a tool to estimate the quality of learning attainable for students when performing laboratory tasks according to written instructions that exist in the chemistry books. Research methods employed in this empirical case study were materials produced by teachers, questionnaire for the participants after training and interview of one teacher. The data is analyzed by methods of qualitative content analysis. The main results from the study give information about the implementation of the revised training model in which teachers worked collaboratively and that the SOLO tool succeeded in raising teachers’ awareness of how the written instructions can reflect the student performance in a laboratory. Teachers became familiar with classifying laboratory assignments to the various SOLO levels and understood how using only the verification type of tasks at school would not help students to develop their higher order cognitive skills (HOCS). Nevertheless, only one teacher out of three presented teacher-experimented material according to training goals. The most challenging phase of the voluntary training was the personal implementation of instructional material. Educational design research is a methodical study of designing, developing and evaluating educational programs, processes and results. We shall discuss the results obtained from the second design experiment and introduce the revised model for the in-service teacher training.
Teaching problem-solving strategies in mathematics
Authors: Fülöp Eva
Published: March 2020

This study uses the methodology of design-based research in search of ways to teach problem-solving strategies in mathematics in an upper secondary school. Educational activities are designed and tested in a class for four weeks. The design of the activities is governed by three design principles, which are based on variation theory. This study aims to contribute to an understanding of how the teaching of problem-solving strategies and strategy thinking in mathematics can be organized in a regular classroom setting and how this affects students´ learning in mathematics. We start by discussing the nature of the concept strategy in relation to the concepts of method and algorithm. Using pre- and post-tests, we compare the development of the students´ conceptual and procedural abilities with a control group. In addition, we use the post-test to investigate the students´ use of problem-solving strategies. The results suggest that these designed activities improve students’ ability to use problem-solving strategies. Moreover, significant differences were found in conceptual and procedural abilities in mathematics, the experimental group improving more than the control groups.
Chemistry teachers as stakeholders of national context-based curriculum reform project
Authors: De Jong Onno
Published: March 2020

The present paper deals with a national curriculum reform project on modular context-based chemistry teaching in the Netherlands. A main characteristic of the project is the use of a ‘bottom-up’ approach for designing the ‘New Chemistry’ curriculum. A document analysis of project-related reports and empirical studies was carried out. The results showed that chemistry teachers were involved in all phases of the project: analyzing current problems, preparing outlines for renewal, developing context-based modules, and testing a pilot version of the curriculum. Some modular learning pathways were composed as exemplar tools for supporting teachers. Results at the end of the curriculum project showed that positive opinions about modular context-based teaching were expressed by about half of the interviewed teacher-innovators and about one-third of the teacher-followers. Nevertheless, negative opinions were expressed by an important minority of teachers. Implications for empowering teachers for modular context-based chemistry education are discussed.
