Experimentation is a contributing factor to the interest and meaningful learning of Science. In Geology and Earth Science, the effects of soil textures, settlements, and water-holding capacity are parameters for landslides in Barotac Viejo and other flooded areas. Landslides are triggered during heavy rainstorms, causing severe property damage and…

Estimation of soil texture is an essential skill for soil scientists, but a difficult skill to learn. We compared two approaches for teaching soil texture: the traditional flowchart approach and an experimental self-calibration method. Three lab sections of an introductory soil science class were assigned to learn by the flowchart method (n = 60)…

Laboratory classes effectively enhance student understanding and appreciation of course concepts. With course delivery suddenly shifted into the online format due to the COVID-19 pandemic, four laboratory exercises in each of two introductory-level soil science courses were converted into virtual sessions delivered in the form of…

Literature circles are student-led, small-group discussions that promote active learning and engagement with literary texts. The objective of this study was to assess the impact of literature circles on student engagement and learning outcomes in a pedology course. For various reading assignments throughout the semester, students either…

A laboratory exercise was developed for the study of the effect of three cations (Al, Ca, and Na) on the flocculation and dispersion of soil particles. The exercise was designed for Soil Science undergraduate students in the second-course in the Agricultural Engineering and Environmental Sciences department at the University of Vigo. The students'…

As instructors return to in-person teaching and learning following online teaching during the COVID-19 pandemic, we can build from the experiences gained and incorporate various online resources into our campus-based classes. Drawing from student evaluations of teaching, a post-course student survey and learning management system (LMS) analytics,…

Studio-style course delivery involves the integration of laboratory activities with lecture elements of the course, with the goal of increasing student learning and satisfaction through directly linking laboratory and lecture concepts while focusing on active learning. In order to evaluate the effectiveness of studio delivery of an introductory…

A survey of introductory soil science or equivalent (ISS[subscript e]) instructors and courses at 79 institutions differing in land-grant status (38 land-grant, 41 non-land-grant) and Carnegie category (48 doctoral, 16 masters, 10 baccalaureate, 2 associate, 3 respondents did not identify by Carnegie classification) was conducted to collect…

Revising standard structured academic programs by incorporating research throughout the curriculum is a modern trend at universities worldwide. There are numerous publications on inquiry-based learning (IBL) in individual courses, but few provide evidence both of success at the program level and of synergy in the teaching--research nexus. Our…

To support elementary school students in finding a solution to an engineering problem, the authors developed a series of five lessons using the 5E Instructional Model (Bybee 2014). The lessons align with the "Next Generation Science Standards" and the "Common Core State Standards" and integrate the teaching and learning of…

The global scale of climate change may seem beyond many high school students' comprehension. To complicate matters, climate change has emerged as a political issue that pits candidates, neighbors, and sometimes teachers and students against each other (Kahan 2015). The "Next Generation Science Standards" (NGSS Lead States 2013) call on…

This column focuses on promoting learning through assessment. The formative assessment probe in this month's issue can be used as an initial elicitation before students are introduced to the formal concepts of weathering and erosion.

In this article, we describe a fourth-grade inquiry unit on soil. The unit was designed and taught by preservice elementary teachers as part of a university science methods course. Using a student-driven inquiry approach to designing curriculum, the unit engaged fourth graders in learning about the physical properties soil, erosion, worms, and…

This article reports the efficacy of a research-based learning (RBL) exercise on hydropedology of arid zones, with guided and open research projects (OPR) carried out by teams of undergraduate students in Oman. A range of activities and assessments was used to support student learning during the three-month course. Assessment included monitoring…

Allowing students to create their own investigations and experiments to test hypotheses and answer essential questions is crucial to actively involving students in learning. It also provides them with opportunities to develop critical thinking and process skills. In this article, the authors explore a process called "BIDDI" ("Brainstorm,…
