The aim of this study is to make a situation assessment of student views on the processing of socioscientific issues through scientific scenarios.As a sample of socioscientific issues, the 'DNA and Genetic Code' unit, which is included in the secondary school science curriculum, was taken as the basis. The study was conducted with 8th grade students in a public school. As a method, a case study was used, which allowed the students' views to be examined in depth. The data were collected with a opinion form and semi-structured interviews. The opinion form data were analysed by content analysis, and semi-structured interviews were analysed by descriptive analysis. At the end of the study about the teaching of the socioscientific issues of ‘DNA and Genetic Code’ unit through scientific scenarios, it was revealed that the students thought that their academic achievement increased, they provided permanent learning, scientific scenarios were effective in associating lessons with daily life, and their awareness of social issues increased. It was also understood that they discovered skills such as critical thinking, decision-making and empathy in themselves at the end of the applications. According to the findings obtained from the students, the teaching of socioscientific issues through scientific scenarios increases the interest and motivation towards the lesson, makes the lesson enjoyable and fun, and facilitates understanding. In line with the experiences and findings obtained from the applications, suggestions were made for the use of scientific scenarios in the teaching of socioscientific issues.
In recent years, countries have focused specifically on improving thinking skills in their science education programs. One of the science lesson methods that can be used to activate the use of thinking processes is scientific scenarios. In this direction, the aim of the study is to investigate the effect of socioscientific subject-based instructional experience, which includes scientific scenarios in science lessons, on students' logical thinking skills. The study was carried out in the "DNA and Genetic Code" unit, which especially includes some socioscientific issues. The research was designed according to the quasi-experimental pattern with unequal control group among the pre-test-post-test control group designs, and it was conducted with a total of 36 eighth grade students from the experimental and control groups. The data were collected using the logical thinking group test and an individual information form. According to the study findings, it was understood that scenario-based teaching had an important effect on developing students' logical thinking and in passing their developmental period to the next stage. This finding shows that the processing of some socioscientific science issues with scientific scenarios is effective in increasing students' logical thinking skills.
This research evaluated the effect of guided inquiry approach-based laboratory activity within the scope of lifelong learning, in which daily life context is used, on developing pre-service science teachers' learning processes. The study groups the research consisted of six pre-service science teachers who were seniors in the science education department at a university in the west of Turkey. The holistic single-case design was used as the research method in this study. One of the topics related to enzymes we encounter in many areas of daily life is the concept of enzymatic browning. In this study, starting from a daily life context, an activity that includes the chemical change emphasis underlying the enzymatic browning event and the factors affecting the work of enzymes is discussed. In this context, the guided inquiry learning approach, in which the hypothetico-deductive reasoning cycle is used in laboratory practices in teacher education, is based on the activity. At the end of the activity, experiment reports, science journals, and concept maps were evaluated. As a result of the evaluation, it was seen that the students not only designed scientific research and tested their hypotheses consistently and accurately but also obtained the subject gains related to enzymes and chemical change. Since it is understood that the activity supports lifelong learning in terms of both the skills developed and the ideas reflected by the pre-service teachers, using similar practices in teacher education can be recommended.
Bu araştırmada farklı bilişsel stildeki fen bilgisi öğretmen adaylarının rehberli sorgulayıcı öğrenme yaklaşımı temelli laboratuvar uygulamalarına ilişkin görüşlerinin belirlenmesi amaçlanmıştır. Araştırmanın çalışma grubunu bir devlet üniversitesinde öğrenim gören altı fen bilgisi öğretmen adayı oluşturmaktadır. Bu araştırmada nitel araştırma desenlerinden durum çalışması kullanılmıştır. Durum çalışması desenlerinden iç içe geçmiş tek durum deseninin kullanıldığı araştırmada öğretmen adayı görüşleri, uygulama sonrası yapılan odak grup görüşmesi ile belirlenmiştir. Farklı bilişsel stildeki öğretmen adaylarının rehberli sorgulayıcı öğrenme yaklaşımı temelli laboratuvar uygulamalarına ilişkin görüşlerine yönelik nitel veriler üzerinden içerik analizi yapılmıştır. Araştırma sonucunda öğretmen adayları yapılan uygulamanın açık uçlu doğada olmasının, bilimsel düşünme alışkanlığı geliştirmeleri, olayları farklı bakış açısı ile görebilmeleri, deneylerin motivasyon arttırıcı ve eğlenceli olmasına katkı sağladığı görüşündedirler. Adaylar aynı zamanda deneylerde tümdengelim yoluyla akıl yürütme döngüsünün kullanımının döngünün içeriksel ve yapısal özelliklerinden dolayı katkı sağladığını da belirtmişlerdir. Öğretmen adaylarının hem deneylerin açık uçlu olması hem de deneylerde tümdengelim yoluyla akıl yürütme döngüsünün kullanımının deney öncesi ön bilgileri kontrol etme sürecine olan ciddi katkısına vurgu yaptıkları görülmektedir. Araştırmada öğretmen adaylarının rehberli sorgulayıcı öğrenme yaklaşımı temelli laboratuvar uygulamalarına ilişkin görüşlerine ek olarak ilgili alan yazın doğrultusunda alan bağımlı / alan bağımsız bilişsel stiller açısından rehberli sorgulayıcı öğrenme yaklaşımı temelli laboratuvar uygulamalarının kullanımına ilişkin öneriler de sunulmuştur.
