Science Investigations

<p>The authors reviewed their approaches to facilitating inquiry-based science courses from 2005 through 2010 in a fully online master's degree program at Walden University designed to help teachers bring inquiry-based science to their students. The purpose of this paper is to illustrate their interaction-engagement approach in facilitating online courses, which focused on a guided inquiry approach to build understanding of core science concepts using hands-on experimental science investigations.</p>

AbstractMassive open online courses (MOOCs) provide hundreds of students with teaching materials, assessment tools, and collaborative instruments. The assessment activity, in particular, is demanding in terms of both time and effort; thus, the use of artificial intelligence can be useful to address and reduce the time and effort required. This paper reports on a system and related experiments finalised to improve both the performance and quality of formative and summative assessments in specific data science courses. The system is developed to automatically grade assignments composed of R commands commented with short sentences written in natural language. In our opinion, the use of the system can (i) shorten the correction times and reduce the possibility of errors and (ii) support the students while solving the exercises assigned during the course through automated feedback. To investigate these aims, an ad-hoc experiment was conducted in three courses containing the specific topic of statistical analysis of health data. Our evaluation demonstrated that automated grading has an acceptable correlation with human grading. Furthermore, the students who used the tool did not report usability issues, and those that used it for more than half of the exercises obtained (on average) higher grades in the exam. Finally, the use of the system reduced the correction time and assisted the professor in identifying correction errors.

Post Hoc

Students often struggle to connect concepts with evidence, sometimes because development of research skills has not been emphasized in their science courses. We developed a strategy and protocol to train high school students in research and experimental investigation of questions related to course material on legume biology. The richness of this subject matter allows for adaptations of our framework to address diverse areas of science, including principles in ecology, environmental science, agriculture, microbiology, and evolution. Our framework includes a hands-on classroom inquiry that investigates the symbiotic relationship between nitrogen-fixing rhizobial bacteria and legumes. This student-led, inquiry-based project employs an intellectually demanding, hands-on method of education to build critical research skills using an adaptable model and inexpensive materials. We also report positive student feedback from a post hoc survey to gauge student attitudes toward the activity and the effectiveness of this framework.

Biology Laboratory

This study examined the effects of inquiry-based biology laboratory applications on pre-service biology teachers’ scientific process skills, attitudes, self-efficacy, and self-confidence in the laboratory. In this context, many related tests and scales were applied to first-year students of biology education (N=25). The research adopted the pre-test and post-test control group model. The results showed that laboratory practices based on both the corroborative and the guided inquiry approach increase the scientific process skills of the prospective teachers. Guided inquiry-based laboratory practices have increased the attitudes of pre-service biology teachers toward laboratory lessons. However, self-efficacy and self-confidence of the pre-service teachers taking part in corroborative laboratory practices increased, while guided inquiry methods did not have a significant effect on self-efficacy and self-confidence. The findings of the study highlighted the importance of a guided inquiry approach in the laboratory applications related training of pre-service biology teachers.

In this paper we report on the practical outcomes of Software Studio (SS) undergraduate course, but also on a graduate Software Engineering for Internet Applications (SEIA) course, both of which are taught collaboratively by IT and non-IT faculty members. In the latter, students are assigned to projects proposed by actual customers and work together in teams to deliver quality results under time and resource constraints. We are interested in the learning results, such as skills acquired, e.g. by analysing the interaction between students and customers to determine how and to what degree the students transform through project based collaborative learning. As for the SEIA course, the primary goal is to allow students to manage a relatively large number of tools with little prior knowledge and having to work out how to obtain detailed information about given features, when required. In other words, students have to understand the key ideas of web application development in order to be able not only to apply technical knowledge, but also to successfully interact with all the stakeholders involved. In the process, we look for the added value of collaborative teaching, aiming at equipping the participants with both technical and non-technical skills required for their prospective jobs.

Laboratory Management

Laboratorium sebagai sarana pembelajaran IPA memiliki fungsi sangat penting dalam menfasilitasi peserta didik membangun kompetensi ilmiah. Oleh karena itu diperlukan manajemen yang tepat oleh pengelola yang memiliki kompetensi. Kegiatan workshop ini dilakukan untuk memperkuat kompetensi guru dalam optimalisasi fungsi laboratorium IPA. Kegiatan dilakukan dalam bentuk ceramah-tanya jawab, diskusi, praktik laboratorium berbasis inquiry dan latihan implementasi manajemen laboratorium di laboratorium sekolah. Peserta kegiatan sebanyak 19 orang guru IPA SMP di Kota Banjarmasin dan Kabupaten Banjar. Kegiatan workshop ini mampu memperkuat pengetahuan dan keterampilan guru SMP dalam pengelolaan laboratorium dan keterampilan merancang dan melaksanakan praktikum berbasis guided inquiry serta kemampuan menerapkan hasil workshop di laboratorium IPA sekolah. Peserta workshop sangat antusias selama mengikuti kegiatan dan merasa sangat terbantu dalam mengatasi kendala dan permasalahan yang dialami guru-guru IPA di sekolah masing-masing. Perlu perluasan peserta workshop di berbagai daerah agar mampu meningkatkan peran laboratorium dalam mendukung tujuan pembelajaran IPA yang meliputi pengetahuan, sikap dan keterampilan ilmiah peserta didik.The laboratory has a very important function as a means of science learning to facilitate students to build their scientific competences. Therefore, we need proper management which is performed by the competent laboratory managers. This workshop was conducted to strengthen the teachers’ competence in optimizing the functions of a science laboratory. The workshop methods including lectures, discussions, inquiry-based laboratory practices and implementation of school’s laboratory management. The participants were 19 junior high school science teachers in Banjarmasin City and Banjar Regency. This workshop was able to strengthen teachers’ knowledge and skills in mining school’s laboratory, teachers’ skills to design and implement guided inquiry-based practicum, and teachers’ ability to apply skills in managing science laboratory. The participants appear very enthusiastic during the workshop and they felt greatly helped in overcoming many laboratory obstacles and problems. It is necessary to expand the workshop’s participants in various regions in order to increase the role of laboratories in supporting science learning objectives which include scientific knowledge, attitudes, and skills of students.
