The purpose of this study is to comparatively investigate the science teaching curricula in Turkey, which have undergone changes four times since the millennium. For this purpose, we carried out a technical and taxonomic examination of the learning outcomes listed in the science curricula that were introduced in 2000, 2005, 2013, and 2017 concerning Revised Bloom Taxonomy (RBT). In this study, the document analysis method was used. We classified a total of 2,613 learning outcomes in our analyses, which were limited to those related to the cognitive domain. The reliability score of the classifications was .89 according to the equation proposed by Miles and Huberman. The analyses showed that the teaching curricula decreased the intensity of the focus on knowledge and cognitive skills rather than making fundamental changes. Moreover, there was significant parallelism among the examined curricula in terms of the dimensions of the taxonomy. Using national-level results in international exams such as PISA (Programme for International Student Assessment) and TIMSS (Trends in International Mathematics and Science Study), we concluded that Turkey had not been successful enough in developing the examined curricula.

The purpose of this study is to determine the distribution of Science achievements in Life Studies Course Curricula of 2009, 2015 and 2018 regarding the knowledge and cognitive process dimensions of the Revised Bloom Taxonomy and to comparatively examine the resulting distributions. This study adopted document analysis. While conducting the analysis, we classified the achievements as factual knowledge, conceptual knowledge, operational knowledge and metacognitive knowledge in the accumulation of knowledge dimension and as remembering, understanding, applying, solving, evaluating and creating in the cognitive process dimension. Based on our findings, we concluded that achievements of 2009, 2015 and 2018 curricula focused on remembering, understanding and applying levels in the cognitive dimension and factual and conceptual knowledge dimensions in the knowledge dimension. We present some recommendations for teachers and teacher candidates, which they can use while preparing their lesson plans.

Bu çalışmanın amacı, ortaokul fen bilgisi ders kitaplarında yer alan soruları TIMSS 2011 programı çerçevesinde ele alınan öğrenme alanı, bilişsel alan ve soru tipleri bakımından analiz etmektir. Bu amaç doğrultusunda altıncı, yedinci ve sekizinci sınıf fen ders kitaplarında yer alan sorular içerik analizi yöntemi kullanılarak incelenmiştir. Bulgular, fen bilgisi ders kitaplarındaki sorularının çoğunluğunun bilme bilişsel becerisine vurgu yaptığını, bununla birlikte çok az kısmının (yaklaşık yüzde üç) üst düzey bilişsel beceri gerektirdiğini ortaya koymaktadır. Dahası, fizik öğrenme alanı ders kitaplarındaki soruların yarısından fazlasını kapsamakta iken yer bilimleri öğrenme alanı soruları küçük bir oranını (yaklaşık yüzde on) temsil etmektedir. Bunlara ek olarak, fen bilgisi sorularının büyük çoğunluğu çoktan seçmeli sorulardan oluşmakta iken çok az kısmı açık uçlu sorular olarak ifade edilmiştir.
