The Effect of Science Teaching Enriched With Technological Applications on the Science Achievements of 7th Grade Students

This study aims to research the impacts of science teaching enriched with technological applications on the science course achievement levels of 7th grade students. 13 weeks long research was carried out with 7th grade students studying at a state secondary school in Turkey in 2016. In the study, quasi-experimental method, experimental design with the pretest-posttest control group was used. There were 83 students (control=42, experiment=41) in the study group. “Science Achievement Test” developed by the researchers was used as data collection tool. There are 28 multiple-choice, four-choice items in the achievement test covering subjects taught, and the KR 20 reliability coefficient is 0.78. “Science Achievement Test” was used as the pretest, posttest, and follow-up test. Teaching was carried out by the same science teacher in the science class in both the control and experiment groups. In the control group, student-centered learning approach suitable to the 2013 Science Course Curriculum was given to the students, and no experimental procedure was applied. In the experiment group, 2013 Science Course Curriculum was followed, and teaching was carried out with technology enriched science teaching applications. At the end of the research, it was found that the achievement levels of the experiment group with the technology enriched science teaching applications increased significantly and was higher at a meaningful level than the achievement of the control group students. According to this findings, it can be suggested that technology enriched teaching should also be used in science teaching to address individual differences by enriching teaching

Impact of Technological Pedagogical Content Knowledge Based Education Applications on Prospective Teachers’ Self-Efficacy Belief Levels Toward Science Education

The purpose of this study is to examine the impact of technological pedagogical content knowledge-based education applications on prospective teachers’ self-efficacy belief levels toward science education. The study was conducted on the 3rd year prospective science teachers of a public university and continued for 14 weeks. In the study, quasi -experimental method, pretest-posttest experimental design with a control group. The research was performed in the Instructional Technologies and Material Design courses during the education year of 2015-2016. In the research, one of the classes of the 3rd years was determined as a control and another one as an experimental group. There were 65 students (control=33, experiment=32) in the study group. As the instrument of data collection, the self-efficacy belief levels toward science education scale was used and the scale was applied as pretest, posttest and follow-up test. Cronbach Alpha (a) consistency coefficient of the scale is 0.82. To the students in the experimental group, the education applications based on Technological Pedagogical Content Knowledge were introduced by the researcher; the courses were made with these applications and they were requested to use these applications that they learned in the materials that they were making. As for the control group, the courses were made with the current curriculum. The research results show that the self-efficacy belief levels of prospective science teachers toward science education design is higher in the experimental group than the students in the control group
