Society is changing as the influence of technologies and the implementation of innovative practices are driving change. Change and innovation are not simple processes for all (Rogers, 2003). Yet, companies, corporates and small business are managed and lead to ensure not only efficiency, but also to yield the best possible financial gain. When one analises change in the world of commerce, one does not have to be a rocket scientist to come to the conclusion that there have been tremendous changes. Not only has the ergonomics of buildings and factories changed, there has also been change pertaining to the number of people employed, as technologies afford opportunities to make certain positions that people occupied, redundant. Robotic tools are used more and more in the manufacturing chain to increase productivity and to ensure greater quality, or so we are informed.

The purpose of the research is to analyze the effect of STEM applications on mathematics pre-service teachers' mathematical literacy self-efficacy, technological pedagogical knowledge and mathematical thinking skills and their views on STEM education. This research has been carried out by 29 mathematics pre-service teachers who are schoolers at the educational faculties of Mus Alparslan University. The research was completed in 10 weeks (3 hours per week) in spring semester of 2016-2017 academic year. Mixed research approach was used in the study. "Mathematical Literacy Self-Sufficiency Scale", "Mathematical Thinking Scale", "Technological Pedagogical Area Information Scale" and "STEM Interview Form for Mathematics Pre-service Teachers" were used as data collection instruments. The collected data were analyzed, and it was certain that the STEM applications positively affected the pre-service teachers' mathematics literacy self-efficacy and technological pedagogical content knowledge. However, STEM applications were not seemed to have a positive effect on mathematical thinking. Moreover, when the opinions of the pre-service teachers were examined, it was identified that the STEM applications changed positively the opinions of the pre-service teachers about the mathematical literacy, and that they lacked many subjects such as field knowledge and pedagogy knowledge about STEM education. Suggestions were made in the direction of the findings obtained.

In order to analyse whether or not the characteristic of scientific inquiry activities of textbooks in China satisfy the requirements of China’s new curriculum reforms, content analysis method was adopted to analyze scientific inquiry activities in junior middle school physical textbooks (grade 8) of five editions authorized by the Chinese Ministry of Education. The results show that the inquiry activities in the five versions of textbooks in China cannot meet the requirements of authentic scientific inquiry regardless of the degree of openness or operationality of cognitive processes and are not conducive to develop students’ scientific inquiry skills and scientific reasoning skills. The authors of science textbooks should take note of the latest insights from the world of academia and develop some new authentic scientific inquiry tasks to update textbooks in a prompt manner in order to improve the students’ abilities of scientific inquiry. For the textbook reviewers, the present research not only provides them with specific findings, but also provides them with a method to evaluate textbooks.

The purpose of this research is to compare the previous stereotypes of the scientist image and the current stereotypes of the inventor image among Korean students. For this purpose, three primary schools located in the metropolitan area of Korea were selected under a convenience sampling method, with one class selected for each of the 2nd, 4th, and 6th grades of each school. The conclusions of this research are as follows. First, analyzing students' stereotypes of the inventor image showed that older students had more stereotypes about inventors than younger students did. Second, as a result of analyzing the images according to each indicator, Korean students were found to have stereotypes about the inventor. Third, the symbol of research was expressed together with one of the science-related experiment tool and the making-related experiment tool. Fourth, primary students perceived the inventor as mainly male. Male students mostly drew male inventors and female students mostly drew female inventors. Based on the conclusions obtained through this research, various educational implications to be reflected in primary technology education were suggested to escape the stereotypes of the inventor’s image.

The importance of plants is not as clearly understood as that of animals. This lack of attention is called “plant blindness” and is considered one of the most important problems in biology education. Textbooks do not put much emphasis on plants and, therefore, they may contribute to plant blindness. In this research, ten textbooks used for teaching at the basic education level in Turkey were analyzed for plant blindness using the document analysis method. The words and photographs associated with plants and animals were analyzed. The data analysis did not find any evidence that could lead to a conclusion of plant blindness based on the text and photos of these textbooks. However, if the number of plant and animal species covered is increased, and more words and photos are used to introduce these species, children will become more familiar with plants and animals. Besides textbooks, other educational tools can be analyzed in terms of plant blindness to expand on the related literature.

Critical thinking skills are one of the 21st century skills that are effectively trained by using the OR-IPA and Problem Based Learning (PBL) Model, therefore this research aims to compare the effectiveness of both. Research design used True Experiment with Randomized Subject Control-group Pre-test and Post-test with 94 pre-service physics teachers. Data collected using the critical thinking skills test and the student response sheet, and then analyzed using t-test and N-gain. The results showed: (1) the teaching instruments of OR-IPA and PBL Model have fulfilled the validity requirements (rα ~ .26) and reliability (α = .96 - .99). (2) Each of OR-IPA, PBL, and Conventional Model can significantly increase critical thinking skills at α = 5%, respectively with average N-gain: medium (.60), medium (.48), and low (.14); with the student response of: very positive, very positive, and less positive. (3) The OR-IPA and PBL Model are effective to improve critical thinking skills, while the Conventional Model is ineffective, and the OR-IPA Model is more effective compared to the PBL Model. Implication of this research is that the OR-IPA Model can be an innovative solution to improve critical thinking skills, but there is still a need for repetitive research like this.

The Internet is a service where much information from the world of science, technology, fashion and entertainment can be found. With the development of mobile devices, information from the Internet has become available almost everywhere. This fact should be used to help students learn curriculum e-materials from smartphones, tablets and netbooks. One of the Internet services that can be successfully applied in teaching is a blog. This research has analyzed the effects of using blog as a web tool in biology teaching. The sample under research included 171 students divided into two groups: an experimental group which used a blog and a control group in which the teaching was conducted without a blog as a teaching tool. The students from both groups were first tested by means of a pre-test according to which the groups were at the same level of knowledge of biology and after covering the topic of Cytology both groups did the post-test. The research showed that the students who used the blog had statistically a significantly better result on the post-test. Further research showed that students make equal progress at all levels of knowledge with the help of blogs and that the blog is the most useful to advanced students.
