Ole, Faith Celeste B.; Gallos, Marilou R. – Journal of Turkish Science Education, 2023
This study examined the effects of using the Feedback Loop Model (FLM) in Grade 12 Senior High School (SHS) Physics classes. Using a one-group pretest-posttest design, 58 students identified from a simple random sampling method were tested for their conceptual understanding and engagement with in kinematics. The results showed that students'…

Gong, Tao; Shuai, Lan; Arslan, Burcu; Jiang, Yang Jiang – International Educational Data Mining Society, 2020
This paper investigates differences in students having various scores when designing controlled experiments in two types of scientific inquiry tasks (a fair test and an exhaustive test). We measure temporal features of preparation time and execution time, which reflect respectively the process of question understanding and answer planning and that…

Cano, Junar S.; Olvis, Paul R.; Disca, Berlita Y.; Docena, Aida F. – International Journal of Technology in Education, 2022
The essence of Genetics lies in the understanding of the concepts of Central Dogma of Molecular Biology. Although these ideas are fundamental to the field, they are notoriously difficult to understand and visualize. While simulation-based instructional materials are found to improve the teaching-learning process in science education, little has…

Brown, Janis; Perkins, Robert; Roey, Stephen – National Center for Education Statistics, 2020
This study uses high school transcript data from the National Assessment of Educational Progress (NAEP) High School Transcript Study (HSTS) to determine the validity of student-reported high school courses on the NAEP twelfth-grade student questionnaire. Given that the HSTS is not administered as part of every NAEP twelfth-grade assessment,…

Monroe, Scott – Journal of Educational and Behavioral Statistics, 2021
This research proposes a new statistic for testing latent variable distribution fit for unidimensional item response theory (IRT) models. If the typical assumption of normality is violated, then item parameter estimates will be biased, and dependent quantities such as IRT score estimates will be adversely affected. The proposed statistic compares…

Kim, Sun Young; Hamdan Alghamdi, Amani K. – International Journal of Science Education, 2020
This mixed-methods benchmark study examined Saudi Arabian (SA) Eastern Province secondary students' understandings of the nature of science (NOS) in the Islamic context. To that end, two instruments, the Scientific Epistemological Views (SEVs) and an open-ended questionnaire about science and scientists were employed. Convenience sampling yielded…

Yiling Cheng; I-Chien Chen; Barbara Schneider; Mark Reckase; Joseph Krajcik – Applied Measurement in Education, 2024
The current study expands on previous research on gender differences and similarities in science test scores. Using three different approaches -- differential item functioning, differential distractor functioning, and decision tree analysis -- we examine a high school science assessment administered to 3,849 10th-12th graders, of whom 2,021 are…

Supasorn, Saksri – Chemistry Education Research and Practice, 2015
This study aimed to develop the small-scale experiments involving electrochemistry and the galvanic cell model kit featuring the sub-microscopic level. The small-scale experiments in conjunction with the model kit were implemented based on the 5E inquiry learning approach to enhance students' conceptual understanding of electrochemistry. The…

Cano, Junar S. – International Journal of Technology in Education and Science, 2022
Despite the advantages proffered by technology in science education, little has been done to develop and validate innovative technology-based instructional materials on Central Dogma of Molecular Biology. It is imperative to test any newly generated instructional materials to validate their quality before being widely used. Hence, this study aimed…

Acarli, Dilek Sultan – Journal of Baltic Science Education, 2020
The aim of present research was to examine the effects of interdisciplinary teaching approach on teaching the topic of proteins. In the research, unequal control group model- one of the quasi-experimental research designs was used. The experimental group included 16 students (8 female and 8 male) whereas the control group included 14 students (6…

Kocabas, Sezai; Ozfidan, Burhan; Burlbaw, Lynn M. – EURASIA Journal of Mathematics, Science and Technology Education, 2020
STEM education was a systematic teaching and/or learning process in the STEM fields and a positive correlation existed between STEM education, and the economic prosperity and power of a nation in the globalized world. In recent years, rising concerns have emerged about American STEM education. Many stakeholders wondered that whether the nation has…

Karpudewan, Mageswary; Treagust, David F.; Mocerino, Mauro; Won, Mihye; Chandrasegaran, A. L. – International Journal of Environmental and Science Education, 2015
This study investigated the year 12 students' (N = 56) understanding of chemical equilibrium concepts after instruction using two conceptual tests, the "Chemical Equilibrium Conceptual Test 1" ("CECT-1") consisting of nine two-tier multiple-choice items and the "Chemical Equilibrium Conceptual Test 2"…

Kypraios, Nikolaos; Papageorgiou, George; Stamovlasis, Dimitrios – International Journal of Environmental and Science Education, 2014
In this study, students' understanding of chemical changes was investigated in relation to four individual differences, related to logical thinking, field dependence/independence, convergence and divergence thinking. The study took place in Greece with the participation of students (n = 374) from three grades (8th, 10th and 12th grades) of…

Herrmann-Abell, Cari F.; Hardcastle, Joseph; DeBoer, George E. – Grantee Submission, 2018
We compared students' performance on a paper-based test (PBT) and three computer-based tests (CBTs). The three computer-based tests used different test navigation and answer selection features, allowing us to examine how these features affect student performance. The study sample consisted of 9,698 fourth through twelfth grade students from across…
