- Inquiry-based labs differ from cookbook labs in that inquiry-based labs contain an element of experimentation. A cookbook lab can be performed by a student without understanding any of the theory connected with the exercise whereas inquiry-based labs require a degree of conceptual knowledge for a student to perform the lab. Inquiry-based labs also strengthen and deepen students understanding of topics discussed in lectures or reading assignments. There are many variations and degrees of inquiry in these labs ranging from a lab that is entirely designed by the students to those that include small questions requiring that the students predict the outcomes of a lab or fill in missing information (guided inquiry). A simple specific example of a cookbook lab would be instructing students to measure volume changes between ice and liquid water. The students would be given step by step instructions to follow and would not need to apply any conceptual knowledge. An inquiry based lab on the same topic would allow the students to design their own experiment to discover how the volume of liquid water differs from that of ice. One goal of this activity is to introduce inquiry-based lab design. Beyond lab design, lab supervision is crucial to encouraging students to use their conceptual knowledge when doing a practical lab. Lab assistants or teachers who are involved in the lab can use student questions to encourage deeper understanding. This case study includes a role-play exercise for this skill. This case study has been designed to be used in science education courses for both graduate student laboratory assistants and lecturers or professors in natural sciences at the university or college level. It includes discussion and role-play of a hypothetical laboratory. No specific knowledge of biology or chemistry is needed beyond high school level to complete this task, though knowledge of the existence of microorganisms (yeast) and proteins is assumed. In addition, this activity is suitable for participants with little or no pedagogics training.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Using a synthetic approach to organic materials chemistry, this book sets forth tested and proven methods and practices that make it possible to engineer organic molecules offering special properties and functions. Throughout the book, plenty of real-world examples demonstrate the countless possibilities of creating one-of-a-kind molecules and supramolecular systems to support a broad range of applications. The book explores applications in both materials and bioorganic chemistry, including molecular electronics, energy storage, sensors, nanomedicine, and enzyme engineering.Organic Synthesis and Molecular Engineering consists of fourteen chapters, each one contributed by one or more leading international experts in the field. The contributions are based on a thorough review and analysis of the current literature as well as the authors' firsthand experience in the lab engineering new organic molecules. Designed as a practical lab reference, the book offers:Tested and proven synthetic approaches to organic materials chemistryMethods and practices to successfully engineer functionality into organic moleculesExplanations of the principles and concepts underlying self-assembly and supramolecular chemistryGuidance in selecting appropriate structural units used in the design and synthesis of functional molecules and materialsCoverage of the full range of applications in materials and bioorganic chemistryA full chapter on graphene, a new topic generating intense researchOrganic Synthesis and Molecular Engineering begins with core concepts, molecular building blocks, and synthetic tools. Next, it explores molecular electronics, supramolecular chemistry and self-assembly, graphene, and photoresponsive materials engineering. In short, it offers everything researchers need to fully grasp the underlying theory and then build new molecules and supramolecular systems.

Green Energetic Materials, Chapter 2: "Theoretical Design of Green Energetic Materials: Predicting Stability, Detection, Synthesis and Performance"

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Since the end of the 20th century it has been increasingly realised that the use, or production, of many energetic materials leads to the release of substances which are harmful to both humans and the environment. To address this, the principles of green chemistry can be applied to the design of new products and their manufacturing processes, to create green energetic materials that are virtually free of environmental hazards and toxicity issues during manufacturing, storage, use and disposal. Active research is underway to develop new ingredients and formulations, green synthetic methods and non-polluting manufacturing processes.Green Energetic Materials provides a detailed account of the most recent research and developments in the field, including green pyrotechnics, explosives and propellants. From theoretical modelling and design of new materials, to the development of sustainable manufacturing processes, this book addresses materials already on the production line, as well as considering future developments in this evolving field.Topics covered include:Theoretical design of green energetic materialsDevelopment of green pyrotechnicsGreen primary and secondary explosivesOxidisers and binder materials for green propellantsEnvironmentally sustainable manufacturing technologies for energetic materialsElectrochemical methods for synthesis of energetic materials and waste remediationGreen Energetic Materials is a valuable resource for academic, industrial and governmental researchers working on the development of energetic materials, for both military and civilian applications.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- In this chapter, it is first shown how a number of steps in the scientific process in this field of chemistry can be improved by naming and understanding the topology of three-dimensional networks and can be the coordination polymers, metal–organic frameworks, or hydrogen bonded systems. Specifically, the discussion is centered on the use of network analysis and graph set analysis to (i) understand the products we get, (ii) compare these materials to what others have made, (iii) communicate our results to colleagues, and (iv) truly make something new by design. The topology symbols by O'Keeffe, Wells, and others are introduced, and the reader is given a step-by-step guide on how to obtain the topology of a 3D net. Finally, graph set analysis is introduced, and its utility in supramolecular chemistry and network analysis discussed.

Ämneslitteracitet inom skolans naturvetenskap - tolkning av ord för att förstå helheter
- 2022
-
Ingår i: Ämneslitteracitet och inkluderande undervisning / Anders Jakobsson, Pia Nygård Larsson, Lotta Bergman (red.).. - Lund : Studentlitteratur. - 9789144152417 ; , s. 179-212
-
Bokkapitel (refereegranskat)abstract
- Litteracitet har traditionellt beskrivits utifrån människors läs- och skrivförmågor eller förmågan att hantera siffror och enkla problemlösningssituationer i vardagen. I den här antologin tar författarna i stället avstamp i ett vidgat perspektiv på begreppet för att undersöka hur det gestaltar sig inom olika ämnesområden. Genom exempel från olika klassrum och ämnen belyser författarna ämneslitteracitet och ger uppslag till hur lärare kan arbeta för att utveckla och förstärka elevers ämnesspråkliga kunskaper och förmågor. Utgångspunkten är att ämneslitteracitet och ämneskunskaper utvecklas i nära samspel, vilket återspeglas i ett specifikt agerande som tar sig olika uttryck i olika ämnen. Här diskuteras även på vilka sätt som fokus på ämneslitteracitet och ett språk- och kunskapsutvecklande arbetssätt kan medverka till en inkluderande undervisning. Boken vänder sig främst till lärarstudenter och lärare i grundskola, gymnasieskola och vuxenutbildning
