The Difference

This study aims to determine the perceptions of the use of scientific process skills of in-service and pre-service teachers working in branches related to science courses in secondary and high schools. Therefore, this research was designed based on a relational survey model and was carried out with 150 science teachers in Turkey and 260 pre-service teachers from two different universities. The Scientific Process Skills Perception Scale was used to measure their perceptions of scientific process skills. An independent sample t-test was applied to compare the difference between the perceptions of scientific process skills of in-service and pre-service teachers. The results showed no significant difference between the two groups. The ANOVA results further showed that the duration of teachers’ service did not make a significant difference in their scientific process skill perceptions. The results of this study revealed that in-service and pre-service teachers should be supported with training to reduce their reservations about using scientific process skills.

The purpose of this study was to examine pre-service science teachers’ perceptions toward additional instructional strategies in biology laboratory applications in the scope of blended learning. This study used a mixed-methods sequential explanatory design model and was conducted with 69 students who study in their 2nd year in the department of science education at a state university in Turkey. Academic achievement test, personal information form, student feedback form, semi-structured interview, and additional instructional strategies were used to collect the data. To determine students’ academic achievements, the scores obtained from the academic achievement test were used from a pre-test and post-test and additional instructional strategies (discussion question, reflection paper, task assignment, and quiz) were used. In addition, students’ views and satisfaction levels toward the course were examined. For data analysis, descriptive statistics, One-way ANOVA, and content analysis were used. The results of the study showed that students’ academic achievement scores showed a significant difference in terms of the additional instructional strategies. In addition, students’ evaluation scores and satisfaction levels about the learning process were high, but there was no significant difference in terms of additional instructional strategies. In the future, conducting similar studies with wider samples could be effective in terms of contributing to the relevant literature at different education levels and different disciplines.

Science teaching emerged due to an attempt to understand the world around us and a sense of wonder at nature and survived until today by means of being supported by new research and findings. The implementation of science in schools is carried out with curriculums. The main purpose of the curriculum of science courses is to train all students in science literacy regardless of their individual differences. According to the educational program of sciences courses, audiovisual aids used in education with a learning objective which is one of these aids is one of the most effective ways to ensure permanent learning. Within this concept the purpose of the study is to determine the opinions of pre-service science teachers about the curriculum of the science lesson based upon the stories in the 3-Idiots movie. In this research, phenomenology research was used. As a data gathering tool, three semi-structured interview questions prepared accordingly to “3- Idiots” movie were used. According to the participants, the science curriculum must be lead in investigating, interrogating, criticising, curiosity and reconnoitering in terms of features that must be acquired for being scientifically literate individuals. Key words: Pre-service science teachers’ perceptions, science, science curriculum, 3-idiots movie.

Introduction: Cigarette smoking is a prime risk factor for cardiovascular morbidity and mortality. Chronic smoking results in autonomic dysfunction leading to increased cardiovascular risk in smokers. The present study was planned to study the effect of smoking on the Cardiovascular Autonomic Functions among smokers. Materials and Methods: Fifty male subjects who were in the age group of 25 to 45 years. They were grouped into 25 smokers and 25 non-smokers. The participant subjects were selected among the staff members, residents and the patients from the routine OPD in SVIMS. Prior to study, they were informed about the procedure and the purpose of the study tests and written consents were obtained from them. The Cardiovascular Autonomic Function Tests were assessed by using a POLYGRAPH which was available in the department. Results and Conclusion: After applying the ‘t’-test for the difference between the two sample means, it was observed that there was a highly significant difference between the mean values of the BMI(i.e.p<0.01) and the para-sympathetic function tests among the smokers and the non – smokers(i.e.p<0.00). The Resting Heart Rate had significantly increased and the Deep breathing difference, the postural tachycardial index (Response to standing) and the Valsalva Ratio had significantly decreased in the smokers as compared to those in the non – smokers. After applying the ‘t’-test for the difference between the two sample means, it was observed that there was no significant difference between the mean values of the Postural hypotension test (i.e. p>0.05) and that there was a highly significant difference between the mean values of the Sustained handgrip test in the smokers and the non – smokers (i.e. p<0.00). KEY WORDS: Cardiovascular autonomic function tests, Smoking, Resting heart rate.
