This study investigated the effectiveness of student-centered instruction on eighth-grade students' conceptual understanding of photosynthesis. The study employed a Quasi-experimental research method. The data collection instruments included were multiple-choice tests, observations, and an informal assessment. The pretest and posttest were…

Environmental literacy related to the utilization of medicinal plants in the community provides a foundation for the younger generation to take an active role and form an attitude of care and responsibility for environmental sustainability. The current research aims to introduce the Inquiry-Etnobotany (IEb) learning model to enhance students'…

In this article, a low-cost and pocket-sized setup for measuring CO[subscript 2] is presented. This setup is based on Arduinos, making it economic and open to modifications or improvements that satisfy other needs. It is composed of an Arduino board, a CO[subscript 2] sensor, an SD-card module, and a control panel. The device has been tested in…

This study explored how the use of three different pedagogical frameworks (community science, storytelling, and inquiry-based learning) influenced learners' awareness and appreciation of flagellate plants in an undergraduate online botany course. Students' opinions, attitudes, and perceptions toward science were explored using the Classroom…

This paper reports on our use of a fine-grained learning progression to assess secondary students' reasoning through carbon-transforming processes (photosynthesis, respiration, biosynthesis). Based on previous studies, we developed a learning progression with four progress variables: explaining mass changes, explaining energy transformations,…

Purpose: The purpose of this paper is to explore how web-based science curriculum materials designed to develop autonomous learners can succeed in Brunei. In this instruction, designed to prepare students to independently explore new topics, students and teachers take new roles. Students collaborate with a peer to engage in inquiry and teachers…

The paper reports on an empirical study adopting a mixed research method, aiming at improving primary students' collaborative problem solving competency in project-based learning with productive failure (PF) instructional design in a seamless learning environment. Two Grade Six classes participated in a project-based learning of "Plant…

We compared designs of guidance to support students while interacting with dynamic visualizations of complex scientific phenomena in inquiry instruction. Three hundred thirty-two 7th-grade students were randomly assigned to either a reading or a generating condition and completed a web-based inquiry unit focusing on energy concepts in…

This study examined 6th graders' use of the VoiceThread app as part of a science inquiry project on photosynthesis and carbon dioxide emissions in terms of their ability to engage in causal reasoning and their use of the affordances of multimodality, collaboration, interactivity, and connectivity. Students employed multimodal production using…

Many household gardeners accumulate considerable knowledge of plant biology through a range of informal learning sources. This knowledge seldom relates to school biology and is driven by interest, keen motivation and what is termed here "vital relevance." A small opportunity sample of 12 gardeners (6 M, 6 F) is interviewed in terms of…

Early involvement of students in hands-on research experiences are known to demystify research and promote the pursuit of careers in science. But in large enrollment departments such opportunities for undergraduates to participate in research are rare. To counteract such lack of opportunities, inquiry-based laboratory module in plant tissue…

Inquiry-based labs have been shown to greatly increase student participation and learning within the biological sciences. One challenge is to develop effective lab exercises within the constraints of large introductory labs. We have designed a lab for first-year biology majors to address two primary goals: to provide effective learning of the…
