This dissertation focuses on three manuscripts all related to bolstering science achievement through recommendations from the National Research Council (NRC) regarding the teaching and learning of science. The manuscripts address meeting the NRC's call to incorporate curriculum and assessment that lead to more in-depth knowledge that can be…

In the last decades, secondary school students have indicated a low interest in science and a lack of awareness of authentic science careers that may impede their aspiration to work in science-related fields in future. To raise students' aspirations, several studies used context-based approaches, but few integrated career aspects into the school…

The main purpose of this study was to explore major factors at student and teacher/school levels affecting middle-school students' science self-efficacy among countries with high science academic performance levels in PISA 2015 data by using various regression algorithms of machine learning and multilevel latent profile analysis (MLPA). Out of…

This study explores the effects of gendered inquiry-based learning (IBL) practices on other science learning experiences and motivations including STEM (Science, Technology, Engineering, and Mathematics) career aspirations. For this, PISA 2015 data representing the Finnish 15-year-old student population has been selected and analyzed by multiple…

Uncertainty is endemic to scientific research practices; therefore, it is also an important element in learning about science. Studies have shown that experiences and management of uncertainty regarding the epistemic practices of science can support learning. Whereas the common strategies of supporting students in handling uncertainty rely on the…

Scientific literacy (SL) has been recognized as the main goal of science curricula documents around the world; however, comparative international curriculum research is limited, especially with Western and African countries. To fill this gap, this study aimed to compare the coverage of SL competencies with the components of knowledge, attitudes,…

Finland and Singapore are both top-performing countries in international assessments such as PISA. Finland has been consistently one of the high-achievers regarding not only students' literacy levels but also educational equity. Similarly, Singapore has continuously shown outstanding performance in PISA. It outperformed all the other participants…

Extracurricular learning plays a key role in shaping students' interest in (not only) biology. The research examined which extracurricular areas related to biology can make biology more attractive for the participating Finnish and Czech students. A 5-point Likert scale questionnaire was administered to 178 Finnish and 195 Czech 9th-grade…

This research compared how the scientific literacy-related goals of the current Chinese and Finnish national science curricula at primary school level are actualised using a revised Programme for International Student Assessment (PISA) scientific literacy framework in the content analysis of the curricula. The content of the curricula focuses…

This study analyzes how students' reported teaching practices of their teachers and their attitudes towards science are related to the science achievements of four high-performing countries/economies in PISA 2015: Hong Kong, China, Canada, and Finland. A study of these regions can shed light on the commonalities of and differences between the…

The integration of artificial intelligence (AI) topics into K-12 school curricula is a relatively new but crucial challenge faced by education systems worldwide. Attempts to address this challenge are hindered by a serious lack of curriculum materials and tools to aid teachers in teaching AI. This article introduces the theoretical foundations and…

Understanding the intellectual demands of an intended curriculum is crucial as it defines the frames for teaching and learning processes and practice during lessons. In this study, upper-secondary school chemistry curricula contents in Czechia, Finland, and Turkey were analysed, and their objectives were compared using the Revised Bloom's Taxonomy…

Most of biodiversity is not considered charismatic and from human's perspective it can be indifferent, problematic, harmful, disgusting, or dangerous. Secondary school students' attitudes towards an unloved species and how it relates to their feelings of disgust in the context of a biology course were studied during a citizen science project where…

Supporting teacher candidates' learning of coherent and well-ordered content knowledge is one of the most important educational aims in subject teacher education. To reach this aim, teacher educators need suitable tools to enhance the formation of such knowledge. In this article, we present an analytical framework to examine conceptual knowledge,…

In 2021, an OECD team undertook analysis of Republic of Türkiye's data from two international assessments--the OECD Programme for International Student Assessment (PISA) and the International Association for the Evaluation of Educational Achievement (IEA)'s Trends in International Mathematics and Science Study (TIMSS). The analysis aimed to…
