Development and validation of a conceptual test for the human circulatory system

Current biology assessments often lack a strong emphasis on conceptual understanding, which may limit students' ability to apply knowledge in real-world contexts. This study aimed to develop and validate a concept test to assess high school student's understanding of the human circulatory system. The test was carefully designed using the revised Bloom's Taxonomy and aligned with the K-12 curriculum. Initial content validation by biology education experts ensured accuracy and relevance, leading to refinements in the test items. Item quality was enhanced through dichotomous Rasch analysis following preliminary testing with 100 students. After a second administration to a new group of 100 students, further analysis confirmed the test's reliability and validity. A final round of testing with an additional 100 students yielded a Cronbach's alpha of 0.79, confirming internal consistency. The study concluded that the developed concept test is valid and reliable for assessing students' understanding of the circulatory system, providing teachers with a tool to refine instructional methods. Future recommendations involve expanding and updating test items to ensure relevance, integrating technology-enhanced questions to improve the assessment of student comprehension, and evaluating reliability across diverse contexts.

Course‐Based Teacher Professional Communities (With District and Union Support) at the Center of Three‐Dimensional Science Teaching

ABSTRACTThis study focuses on how two school districts managed and changed the instructional core—student learning goals, instructional resources and strategies, and assessments—in their required high school biology course as they responded to new state science standards based on the Next Generation Science Standards (NGSS). Biology teachers in both districts had access to NGSS‐aligned resources for their classrooms. Interviews with teachers, district science coordinators, and union leaders revealed how district responses were affected by two institutional logics: academic logics included the criteria that teachers used to choose resources and strategies for their classrooms and professional logics included the roles and responsibilities of district professionals. Participants from District A endorsed a common‐sense experiential academic logic, which recognized teachers' obligations to meet general criteria for content coverage while using their personal experiences and values to make detailed instructional decisions. They also endorsed a professional logic of privacy and noninterference, which recognized teachers' individual autonomy in making decisions about their classroom instructional cores. In contrast, participants from District B described how district professionals empowered a course‐based professional community to make decisions about the instructional core that all biology teachers followed in their own classrooms. We examine how this strategy enabled actions consistent with an instructional improvement logic that supported an NGSS‐aligned instructional core in all biology classrooms. We consider the implications of this contrast for teacher learning in organizational settings—the focus of this special issue.

Antioxidant Activity of Hotong (Setaria italica) Seeds from Buru and its Implications for Biochemistry Learning

Hotong Buru seeds (Setaria italica) are a local wisdom food ingredient in South Buru Regency, Maluku Province, Indonesia. These hotong seeds are widely consumed by the people of South Buru as a staple food substitute for rice.

Research on the Infiltration of Scientific Spirit in High School Biology Teaching Under the Background of Curriculum Ideology and Politics

Curriculum thinking and politics is an exploration of moral education reform and a strategic measure to carry out the fundamental task of cultivating people. High school is a key period for students to form correct values. In addition to ideological and political courses, other courses also need to play the function of educating people, and take courses as the carrier to provide value guidance to students in the process of knowledge imparting and ability training. High school biology is a fundamental course in natural sciences and an important carrier for cultivating students’ scientific literacy. However, through questionnaire surveys and interviews at internship schools, it was found that the infiltration of scientific spirit into high school biology teaching is not ideal. Teachers have insufficient understanding of ideological and political education in the curriculum, and they cannot fully tap into educational materials in textbooks. The methods for infiltrating scientific spirit are relatively single, making it difficult to balance ideological and political infiltration with knowledge teaching. This article selects the scientific spirit as an ideological and political element based on the needs of national development and the characteristics of the discipline, and permeates it into biology teaching. Finally, the teaching effectiveness is evaluated through various methods. The aim is to enrich the theoretical research of thinking and politics in senior biology curriculum, and to provide teaching reference for teachers to cultivate students’ scientific spirit in biology teaching. After conducting questionnaire surveys and interviews with students and teachers, the following conclusions were drawn: firstly, although the teachers and students of the school have a limited understanding of ideological and political education in the curriculum, most of them support the integration of ideological and political education into biology teaching. Secondly, some teachers still place more emphasis on imparting knowledge in their teaching and have not fully utilized the educational value of biology. The implementation of ideological and political education in biology teaching is not ideal. Thirdly, overall, the penetration of scientific spirit in biology teaching is not satisfactory and needs further strengthening. In summary, teachers need to strengthen their exploration of textbooks and deepen their understanding of teaching design in their daily teaching process, in order to continuously improve their ideological and political education for students and fully leverage the educational value of biology. Integrating scientific spirit into biology teaching is not only in line with the ideological and political concepts of the curriculum, but also in line with the core competencies of the discipline, which can better leverage the educational value of biology.

Top-down and bottom-up effects on visual perception during data-based scientific reasoning in the context of population dynamics

ABSTRACT This study investigates the role of visual perception in data-based scientific reasoning within population dynamics. Visual perception involves representational characteristics of stimuli and context-based conceptions, influenced by top-down (contextual assumptions) and bottom-up (data representation) effects. In population dynamics, top-down effects relate to assumptions like natural equilibrium, while bottom-up effects concern how data are represented, typically through line graphs. We assessed pre-service biology teachers’ (N = 20) initial conceptions on population dynamics, categorizing them as either the Balance of Nature (BoN) or Flux of Nature (FoN) metaphors. Participants viewed line graphs depicting population dynamics while eye-tracking technology recorded their visual focus and think-aloud protocols provided verbal data. ANOVA results showed significant differences in eye-tracking metrics between AOI groups of BoN and FoN graphs, but no significant effects between initial conceptions and eye-tracking measures. Heat map analyses revealed that participants focused on visually prominent graph features, especially when interpretation required conceptual knowledge and pattern identification.

Pre-service biology teachers’ knowledge of the 21st-century skills and its associated instructional models: The Indonesian context

Integrating the 21st-century skills into Indonesia’s education system is crucial for equipping students to face future challenges. This study investigates the knowledge of pre-service biology teachers in Indonesia regarding the 21st -century skills and their understanding of instructional models that support skill development. Conducted from March to September 2024, the research employed a cross-sectional survey design with a total sampling technique, involving 78 students from a Biology Education program at a public Islamic university in North Sumatra, all of whom had completed a course on biology learning strategies. Data were gathered using questionnaires and analyzed quantitatively to determine key trends. The findings indicate that although most students recognize the significance of the 21st-century skills in biology education, their understanding is limited. Only a small number could identify all essential skills, with creative thinking being the most recognized. Students were well-acquainted with project-based learning as a model for developing these skills but had limited knowledge of the structure and application of other instructional models, such as discovery and inquiry learning. These findings emphasize the need for curriculum improvement to deepen students’ comprehension of various instructional models and the integration of diverse information sources, enabling more effective integration of the 21st -century skills into biology education.

Methodical Principles of Using Mobile Applications in the Professional Training of Future Biology Teachers

The article explores the methodical principles of using mobile applications during the professional training of future biology teachers in higher educational institutions. It is determined that the significance of using modern mobile learning tools is driven by the informatization of the educational process and the necessity to develop key information and digital competencies among future teachers. It is emphasized that forced distance learning requires new teaching methods and tools. It has been found that recently almost all students in general secondary education institutions possess and use mobile phones at a professional level. It is proven that smartphones or tablets can be effective learning tools for the educational process, provided that teachers are skilled in their application. The possibilities of using mobile applications in the educational process of the professional training of future biology teachers are analyzed, revealing methodical approaches to their use: in lectures and laboratory sessions on the methodology of teaching biology, in completing independent work tasks, and in informal or non-formal education.

Analysing the evolution of argumentation quality among pre-service biology teachers amidst the COVID-19 pandemic

ABSTRACT The COVID-19 pandemic has become one of the most controversial issues in recent years. The pandemic’s impact on argumentation skills, crucial for science teachers, needs exploration to understand its effects on how they evaluate evidence and engage in discussions. This study investigated how biology pre-service teachers’ (PSTs) argumentation quality changed over the pandemic’s first two months of social distancing and quarantine. Using qualitative and quantitative methodologies, data were collected through semi-structured interviews, and Toulmin’s Argument Pattern (TAP) was employed to evaluate the arguments. Initially, nearly half of the participants demonstrated low-level arguments. However, during the second round of interviews, a decrease in Level 1 and 2 arguments and an increase in Level 3 arguments were observed. The observed improvements in argumentation quality, particularly in the use of counterclaims, warrants, and rebuttals, underscore the role of increased familiarity with the issue and exposure to diverse information sources. These findings suggest that real-life contexts, such as the pandemic, offer opportunities for PSTs to develop more sophisticated argumentation skills when exposed to multiple perspectives and ongoing engagement with the topic. Understanding these changes can inform teaching strategies and teacher training programmes, especially during global crises. Future research could examine argumentation quality related to issues such as vaccination and COVID-19 variants.

Academic procrastination, task values, and self-efficacy of pre-service biology teachers in online learning based on a gender perspective

Online learning can contribute to increased academic procrastination, often linked to low self-efficacy and perceived task value. This study investigates academic procrastination, self-efficacy, and task values from a gender perspective using a cross-sectional approach with students in their 1st, 3rd, 5th, and 7th semesters. An independent t-test assessed differences between male and female students. Findings showed no significant differences in academic procrastination across genders in any semester; however, notable differences in self-efficacy and task value emerged only in the 5th semester. The lack of significant differences in procrastination is attributed to similarities in environmental, psychological, and social factors, alongside common challenges in time management and distractions. Male and female students demonstrated comparable self-efficacy due to shared academic settings, social support, and media influences, while similar task values stemmed from common interests and experiences. The differences in the 5th semester likely arise from increased academic demands and evolving social dynamics, including gender stereotypes. Future research should employ qualitative methods, such as interviews or focus groups, to gain deeper insights into student experiences. Longitudinal studies could also track changes in self-efficacy and task value over time for a more comprehensive understanding. Targeted interventions to enhance self-efficacy and task value could be particularly beneficial in semesters with significant differences, thereby addressing academic procrastination more effectively.

Integrating islamic values and ecopreneurship in biology: E-lkpd as a learning tool

Integrating entrepreneurship into various subjects, particularly biology, helps foster creativity and problem-solving skills. Often seen as theoretical, biology can link to entrepreneurship through eco-friendly activities. This study aims to develop electronic worksheets (E-LKPD) as a learning tool based on ecopreneurship to increase students' interest in entrepreneurship, especially in waste recycling, within an Islamic context. The method used is Research and Development (R&D) with a 4-D development model Thiagarajan (Define, Design, Develop, and Disseminate), which is modified into 3D (without Disseminate). The instruments used in this research included a checklist of student’s worksheets, interview sheets, content validity for student worksheets, teacher and student response questionnaires, and pre-questionnaire and post-questionnaire entrepreneurship interests. The development process involved validity testing by nine experts, readability testing by 15 students, and field trials by one biology teacher and 36 students. The results showed that the E-LKPD had a very high validity and readability. Teachers and students gave positive feedback during the field trials, and the entrepreneurial interest of students increased significantly, moving from a high to a very high category after using E-LKPD. It indicates that the electronic worksheets are valid and practical for enhancing entrepreneurial interest within biology, particularly in environmental awareness and sustainability. E-LKPD based on ecopreneurship also successfully integrates Islamic values, such as responsibility and concern for the environment. In this way, students not only get academic knowledge, but also entrepreneurial skills.
