The purpose of this study was to explore instructional designs for promoting inquiry practices in secondary school textbooks. Three criteria were employed to select the textbooks: (1) approved by the Ministry of Education in Singapore and the Ministry of Education and Culture in Indonesia, (2) used in secondary schools, and (3) included content…

Background: Although science and technology are viewed as closely related subjects, they are rarely combined in preschools. Purpose: This article investigates preschool teachers' perspectives on integrating digital tools when teaching science, asking how and why they use digital tools, and examining the affordances they experience and obstacles…

Tasks used in the Biology Olympiad (BiO) appear to be promising alternatives to traditional teaching tasks in biology education, as they frequently incorporate inquiry-based elements. This makes them a valuable resource for increasing students' exposure to inquiry activities during classroom instruction. However, for teachers to effectively…

The preponderance of visually oriented and visually complex concepts and information in science classrooms poses significant challenges to learning among students with visual impairment (VI). It is acknowledged that the good quality of practical work promotes the engagement and interest and curiosity of students as well as developing a range of…

In this article, simple models of optical computing circuits (1 x 4 demultiplexer (DEMUX), 4 x 1 multiplexer (MUX), Boolean logic, and half-adder (HA)) are shown with mechanically controlled plane mirrors. Photographs of the proposed computational circuits are also shown. It is very useful for the school student to understand optical logic and…

Previous generations of physics students learned how common machines work, as evidenced by their textbook illustrations. Such understanding of machines that daily life depends on seems to be evaporating. In response, for two decades I have conducted an introductory physics "engine cadaver lab." It offers opportunities for hands-on…

We present an example of a novel, model-based approach to instruction in which learners constructed a representation of a specific phenomenon, evaluated their representation, and then revised it, via an abstraction process, to construct a model. The example took place in high school in the context of solution chemistry. The aim of the instruction…

In the present research, the "DNA Model with Clothespins" activity was designed to teach the subjects of nucleotide, DNA, and DNA replication, which are abstract subjects of science. The aim of the research, which was carried out with 20 students in 8th grade, was to examine the effects of the activity on students' achievement on the…

Objectives: Among the 14 indicators identified in Monitoring Progress, this paper focuses on: the adequacy of instructional time (Indicator 2) and opportunities (Indicator 3) for science learning in grades K-5. This paper considers these two indicators together since they form the basis for opportunities to learn science in elementary school.…

We here propose a simple and fast hands-on activity requiring limited equipment, to introduce students of various levels (bachelor's or high school) and backgrounds (from science to arts) to the chemistry of color. The different colors of stained glass are replicated through the deposition, on ordinary glass slides, of silica coatings colored by…

This research aims to design a sample Arduino-assisted robotics and coding activity in accordance with the 5E instructional model. Also, it aims to set an example for how technology is integrated into science courses, especially in the structuring of abstract and hard-to-understand concepts in science teaching. The activity provides guidance to…

Demand for STEM majors is increasing, yet attrition in STEM classes is common. Exam wrappers and asking students to write on test anxiety have both been shown to be somewhat successful as simple interventions. This study examined the impact of exam wrappers (termed a post-exam wrapper) that specifically included a multiple-choice question about…

The purpose of this study is to elaborate on a sample activity in socio-scientific issues. For this purpose, an activity that lasted for 80 minutes (2 periods) was developed. The implementation process is reported in this paper. The first dimension of the implementation process begins with the tracking of videos that will reflect two different…

The purpose of this study was to evaluate a form of writing instruction designed to teach second-graders to write compare and contrast informational texts. 73% of the participants (N = 45) were White, 22% were Hispanic, 2% were Asian, and 1% were Black, with 63% of the students eligible for free or reduced lunch. 48% of the students were female…

The purpose of "practical work" in chemistry lessons as perceived by teachers varies and does not always correspond with an emphasis on procedural learning. Teachers project various objectives in them. These activities have various characteristics and potential. The goal of this study is to find out the set of characteristics of…
