The article deals with the results of investigation of the process of catalytical photocyclization of aniline and aniline hydrochloride with a-olefins (hexene-1, heptene-1 and octene-1). The following compounds of d- and f-metals are tested as probable catalysts: CuSO4•5H2O, EuCl3•6H2O, PrCl3•6H2O, TbCl3•6H2O, La2O3, MnO2, NiSO4•6H2O, NiCl2•6H2O,…

Botany is traditionally viewed as less attractive than zoology for students, despite the fact that plants play a key role in natural ecosystems. It is hypothesized that survival-relevant information may enhance learner's attention and that this information might be better remembered than others. Additionally, the use of the PowerPoint (PPT)…

Even highly urban environments are settings for outdoor learning of local biodiversity, for they contain easily accessible street tree diversity that students walk pass daily. This study uses pre/post assessments and a tree observation curriculum grounded in scientific observation practice to understand the everyday and scientific tree observation…

The aim of this study was to investigate the role of visual/verbal cognitive style and interactivity level in dynamic and non-dynamic multimedia learning environments. A group of 235 biology students learned about photosynthesis either from a computer-based animation or a series of static pictures with spoken explanatory text. Participants were…

Virtual laboratory activities are flexible approaches to engage undergraduate students in scientific practices during the COVID-19 pandemic. By utilizing online simulations, students can conduct virtual experiments on important biochemical reactions that occur during photosynthesis. The learning module described here provides students with this…

This research aimed to assess the influence of the method of conceptual change on understanding the concept of increasing the mass of plants among 414 students in agricultural education in Slovenia. In photosynthesis, biomass is produced, so understanding these processes is essential for successful agriculture. Data were collected using a…

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 aimed to develop a learning progression (LP) for botanical literacy and assess the impact of a garden-based education course on Thai pre-service science teachers (n = 49). The inquiry- and community-based education course was taught over a 15-week period. To measure botanical literacy, a 50-item multiple-choice test was employed. A…

College level botany education in the United States is gradually being phased out of science and agriculture departments. The absence of botany courses creates a problem because there is an increasing need for trained botanist in the United States workforce, making it important to train teachers in botany so they can inspire the next generation of…

A feature of student--teacher--scientist partnerships (STSPs) involves students working with scientists for the purpose of helping them learn more about how scientists work and think. Previous research on STSPs has generally focused on identifying the best practices of partnerships and on identifying challenges of these partnerships. The study…

This article explores Alexander von Humboldt's influence on the education of young women in early nineteenth-century America. In the past decade, the English-speaking world has seen a resurgence of interest in Alexander von Humboldt. To date however, scholars have devoted relatively little attention to Humboldt's influence on American education,…

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…

In this study, it was aimed to examine the science preservice teachers' conceptual structures about the metabolic events taking place and the forms of energy in a cell. In the study, the descriptive model was used. In the study carried out during the spring semester of the 2017-2018 academic year participated a total of 123 third and fourth year…

To understand the longitudinal effect of a technology-enhanced learning (TEL) environment with reflective guidance on sixth-grade students' learning in a photosynthesis unit in Shanghai, we designed a quasi-experimental longitudinal study with a pre-test and three post-tests, complemented by an examination of students' log data. Our findings show…

This case study examines how teachers preserve and foster the funds of knowledge students bring to school in the Palenque community of Colombia. Data was collected using the funds of knowledge Matrix instrument, open-ended questions, teacher interviews, and non-participant observations. An analysis of data was done using a domain analysis process,…
