Although nature of science (NOS) and nature of scientific inquiry (NOSI) are related to each other, they are differentiated as NOS is being more related to the product of scientific inquiry (SI) which is scientific knowledge whereas NOSI is more related to the process of SI (Schwartz et al. 2008). Lederman et al. ("Journal of Research in…

This study examined the effects of computer animation instructional package on secondary school students' achievement in practical biology in Ilorin, Nigeria. The study adopted a pre-test, post-test, control group, non-randomised and nonequivalent quasi-experimental design, with a 2x2x3 factorial design. Two intact classes from two secondary…

Computer scoring of student written essays about an inquiry topic can be used to diagnose student progress both to alert teachers to struggling students and to generate automated guidance. We identify promising ways for teachers to add value to automated guidance to improve student learning. Three teachers from two schools and their 386 students…

Botanic gardens are popular destinations for school visits to learn about plant-based science. However, little is known about teaching and learning in such settings, in particular about school visits guided by professional botanic garden educators (BGEs). The purpose of this study was to identify the pedagogical moves of the BGEs during guided…

Plants can store the chemical energy required by their developing offspring in the form of triglycerides. These lipids can be isolated from seeds and then converted into biodiesel through a transesterification reaction. This second-year undergraduate organic chemistry laboratory experiment exemplifies the conversion of an agricultural energy…

A theoretical framework is an important component of a research study. It grounds the study and guides the methodological design. It also forms a reference point for the interpretation of the research findings. This paper conceptually examines the process of constructing a multi-focal theoretical lens for guiding studies that aim to accommodate…

A review of research on outdoor learning by Rickinson "et al." (2004) highlights the demonstrable educational benefits and provides a source of support, justification and an evidence base for educators looking to undertake more learning outside the classroom. Bird (2004) also reviewed the widely reported health benefits of outdoor…

Botanic gardens are rich informational environments that exhibit ideas in limited increments due to constraints of time and physical layout. This study addressed a gap in research about experiences and issues of botanic gardens leaders related to implementing educational technologies. Educational theorists Dewey, Kolb, and Bandura provided the…

Purpose: This study developed a framework for quality assessment of diagnoses and advice given at plant clinics. Design/methodology/approach: Clinic registers from five plant clinics in Uganda (2006-2010) were used to develop quality assessment protocols for diagnoses and advice given by plant doctors. Assessment of quality of diagnoses was based…

Children from southern and northern Brazil have a basic knowledge of plants, which they observe during their everyday life. Children ages between 3 to 10 years old (kindergarten & primary school), but the majority of them in the age group of 4-5 (total 145) were asked to draw what they think is a plant (total sample = 332). Afterwards, a equal…

A team of science teacher educators working in collaboration with local elementary schools explored opportunities for science and engineering "learning by doing" in the particular context of urban elementary school communities. In this article, the authors present design task that helps students identify and find solutions to a…

A simple, robust, and reproducible method was developed for the isolation of (-)-menthol from peppermint oil and to study the effect of different types of leaving groups, catalysts, solvents, and tertiary base on the extent of esterification of (-)-menthol to (-)-menthyl acetate. In this experiment, students compare leaving group properties of…

We describe an alternative to the kinds of observation-based lab exercises that are often used to cover animal and plant evolution with respect to transitioning from aquatic to terrestrial habitats. We wrote this activity to address these objectives, but also to model the process of scientific inquiry and to require students to collect and analyze…

A rapid separation of three photosynthetic pigments (chlorophyll "a" and "b" and xanthophyll) from fern ("Polystichum acrostichoides") is described using microscale solvent extraction and traditional thin layer chromatography that minimizes use of harmful chemicals and lengthy procedures. The experiment introduces…

What pedagogical strategies support students from a refugee background connecting to the natural world? What would these strategies look like for fifteen students participating in a language intensive New Arrivals Program (NAP)? These questions were the focus of a small collaborative project set up to investigate the impact of pedagogical…
