Students were introduced to the bean beetle life cycle, experimental design, data collection, and reporting practices. At the end of the semester students exhibited increases in specific areas such as self-confidence in science process skills related to the design and implementation of experiments, as well as scientific reasoning skills.  \nKey words: Bean beetles; neem; inquiry skills; experiment design; biology; instructional strategies; inquiry based learning  \nINTRODUCTION  \nInquiry-based teaching methods reportedly inspire students to develop curiosity, investigative abilities, and teamwork skills. The inquiry-based method provides students with opportunities to actively engage in problem solving rather than simply applying memorized concepts to preconceived experiments (Rehorek, 2004) . In inquiry-based studies, students usually work in teams to explore an issue and develop a scientific question that is solved by applying the scientific method. These activities allow students to learn by active, rather than passive, teaching methods. In the final step, students present the experimental rationale, design, and results to their peers, and respond to feedback and questions. This active form of learning is thought to enhance depth of understanding; studies have shown that students taught using an inquiry-based method score significantly higher on exams than those taught using the so-called cookbook method (Luckie, 2004; Rissing, 2009) . Because of the positive impact of inquiry-based approaches on student learning, these approaches are recommended to be foundational to national changes in the undergraduate biology curriculum (AAAS, 2011) .  \nInquiry-based instruction, like many approaches in science teaching, is not without its challenges. Kirschner et al. (2006) contend that learning in a minimally guided environment is less effective than direct instructional guidance and maintain that changes in long-term memory are required for effective learning and that only guided instruction results in such changes. According to Kirschner et al., a guided-inquiry approach, in which students arepresented with the scientific question, are tasked to  \ndevelop an experiment to test the question, and are then led as a class to an effective experimental design through leading questions, provides a more structured inquiry process than a truly open-ended inquiry. Furthermore, our experience and that of others supports the idea that undergraduate students may be capable of learning scientific content knowledge, but have little to no experience in the actual scientific process (Campbell et al., 2012), thus advocating for a guided inquiry-based approach.  \nAs affiliates ofthe Bean Beetle Curriculum Development Workshop supported by the National Science Foundation (NSF), two of the authors of this study participated in a training workshop in which groundwork was laid for the development of a guided inquiry-based learning exercise using neem (Azadirachta indica) and bean beetles ( Callosobruchus maculatus) . The goal of the above learning exercise would be to help undergraduate students improve their understanding of the nature of science and t","cbCaioOceqJIh7Zk","https://ap.wps.com/l/cbCaioOceqJIh7Zk","pdf",91383,"English","# Abstract\n## Inquiry-based laboratory design\n## Student learning outcomes\n# Introduction\n## Rationale for inquiry-based teaching\n## Challenges and guided inquiry\n# Guided inquiry exercise implementation\n## Training workshop and adaptation\n# Bean beetles background\n## Life cycle and research uses\n## Agricultural impact","[{\"question\":\"What question does the inquiry-based biology laboratory investigate?\",\"answer\":\"It investigates whether material from the neem tree alters bean beetle movements and oviposition.\"},{\"question\":\"How do students participate in the laboratory exercise?\",\"answer\":\"Students are introduced to the bean beetle life cycle, design experiments, collect data, and report results, including presenting experimental rationale to peers.\"},{\"question\":\"What learning gains are reported after the semester?\",\"answer\":\"Students show increases in self-confidence related to science process skills for experiment design and implementation, and they demonstrate improved scientific reasoning skills.\"}]","Inquiry-based Investigation in Biology Laboratories - Does Neem Provide Bioprotection Against Bean Beetles? | PDF",1792079352,15]
