Student ethnicity is one of the internal factors that influence student learning. Bacteriology is a course that examines prokaryotic unicellular living things and is practiced in laboratories that need to implement projects. The aim of this research is to know the distribution of students based on their ethnicity. The research sample was students…

This study aimed to determine differences in students' argumentation abilities on the subject matter of cell structure and function through a scientific approach in high schools with different accreditation ratings. The research design used is "ex post facto." The sampling technique used was purposive sampling, with a total sample of 111…

This study investigated the potential of rubrics to enhance science learning outcomes and the accuracy of peer and self-assessments. We randomly divided 230 upper-secondary students from nine classrooms in public schools into two groups: rubric and non-rubric groups. The research concentrated on five open-ended items pertaining to cell biology and…

Misconception is often experienced by students who study abstract subjects. If this misconception continues to be maintained then the next concept will be wrong and become a difficulty in the learning process, even if a teacher will continue the wrong concept to their students. Therefore, the researchers tried to analyze the misconceptions that…

Critical thinking skills are one of the four main competencies that must be empowered in the 21st-Century Learning. This study aimed to describe students' critical thinking skills through the application of blended-problem-based learning (PBL) in the Cell Biology course. The data sources of this research were 28 students who were taking Cell…

Cell biology is widely considered to be the most important subject for promoting current modern biology. This paper sheds new light on the subject with the development of a diagnostic test to investigate misconceptions among pre-service biology teachers in cell biology. In this study, we developed and validated a diagnostic test -- known as the…

Determining the level of difficulty and student development is important in the learning continuum, especially the anatomical and physiological aspects. This study aimed to collect teachers' opinions about the learning continuum of anatomical and physiological aspects based on its difficulty level. This survey research was conducted in the cities…

The purpose of this research was to determine (1) the effect of e-portfolio use on understanding Biology concepts of students at different academic levels and (2) knowing student responses in the use of e-portfolios. This research is experimental research using a one-shot case study design. Data on understanding students' concepts were collected…

The proper learning strategy, mainly in cellular respiration topic, can be determined as mapping teacher candidate's prior knowledge was done. This study aimed to get the profile of prior knowledge of teacher candidates in cellular respiration topic. This survey research used four-tier diagnostic test as data collection instrument. The number of…

Critical thinking skills are one of the important skills in dealing with the demands and challenges of the 21st century. This study aims to determine the effectiveness of Stimulating Higher-Order-Thinking Skills (Stim-HOTs) model in improving students' critical-thinking skills on cell metabolism topic. This research is quasiexperimental research…
