How to foster STEM learning during Covid-19 remote schooling: Combining virtual and video experiments

Understanding scientific concepts is a fundamental aim of science education. Conceptual understanding can be fostered through inquiry learning with experiments. However, during the Covid-19 pandemic school closures hands-on experiments could hardly be realized. Fortunately, digital technologies allow for conducting experiments virtually by using interactive simulations or observing video recordings of hands-on experiments. In the present study, 154 seventh graders in remote schooling were involved in inquiry learning using either a combination of virtual and video experiments in two different orders or only virtual experiments. We hypothesized that in general inquiry learning fosters students' conceptual understanding in physics, which could be confirmed. Moreover, we expected the combinations to be more effective than learning with virtual experiments only due to the complementary roles of the prior, which was, however, not the case. We conclude that virtual and video experiments can be recommended to teachers if hands-on experimentation is not possible.

Connecting university science experiences to middle school science teaching

Summary Science teachers naturally rely on their university science experiences as a foundation for teaching middle school science. This foundation consists of knowledge far too complex for the middle level students to comprehend. In order for middle school science teachers to utilize their university science training they must search for ways to adapt their college experiences into appropriate middle school learning experience. The criteria set forth above provide broad-based guidelines for translating university science laboratory experiences into middle school activities. These guidelines are used by preservice teachers in our project as they identify, test, and organize a resource file of hands-on inquiry activities for use in their first year classrooms. It is anticipated that this file will provide a basis for future curriculum development as the teacher becomes more comfortable and more experienced in teaching hands-on science. The presentation of these guidelines is not meant to preclude any other criteria or considerations which a teacher or science department deems important. This is merely one example of how teachers may proceed to utilize their advanced science training as a basis for teaching middle school science.     

Teaching children science through storytelling combined with hands-on activities – a successful instructional strategy?

Earlier studies have discussed the usefulness of storytelling and hands-on activities when teaching young children science. However, few studies have investigated the use of the two methods in combination. This study reports on five pre-school teachers’ experience of combining storytelling and hands-on activities in teaching science and their perceived effects of the combination. Interviews with the teachers and a supplementary observation served as the data material, which was transformed into narratives and member-checked by the participating teachers. Some found the combination of methods important while others argued that hands-on activities were effective without the use of stories. The teachers’ enjoyment in adopting the combinatory method and their appreciation of the stories also made a difference.     

Teaching and Learning How to Create in Schools of Art and Design

This article describes the studio model—a cultural model of teaching and learning found in U.S. professional schools of art and design. The studio model includes the pedagogical beliefs held by professors and the pedagogical practices they use to guide students in learning how to create. This cultural model emerged from an ethnographic study of two professional schools of art and design. A total of 38 professors from a total of 15 art disciplines and design disciplines were interviewed and their studio classes were observed. A grounded theory analysis was used to allow the studio model to emerge from audio recordings of interviews and video recordings of studio classes. The model was then validated by 16 different professors at six additional art and design schools. The studio model was found to be general across art and design disciplines and at all eight institutions. The central concept of the studio model is the creative process, with three clusters of emergent themes: learning outcomes associated with the creative process, project assignments that scaffold mastery of the creative process, and classroom practices that guide students through the creative process.

Getting real: the authenticity of remote labs and simulations for science learning

Teachers use remote labs and simulations to augment or even replace hands-on science learning. We compared undergraduate students’ experiences with a remote lab and a simulation to investigate beliefs about and learning from the interactions. Although learning occurred in both groups, students were more deeply engaged while performing the remote lab. Remote lab users felt and behaved as though they completed a real scientific experiment. We also examined whether realistic visualizations improved the psychological and learning experiences for each lab. Students who watched live video of the device collecting their data in the remote lab felt most engaged with the task, suggesting that it is the combination of the realistic lab and realistic video that was of the greatest benefit.     

Teacher development in advanced educational technology

Advanced educational technology promises to improve science teaching and learning. To achieve the posited outcomes, however, teachers must have access to, know how to, have the skills to, and want to use the proposed advanced educational technologies in their teaching. In response, for the past eight years with support from the National Science Foundation, BSCS has conductedENLIST Micros — a teacher development to help science teachers improve their use of microcomputers.ENLIST Micros has three phases — Phase one (1984–1986): BSCS designed, tested, and producedENLIST Micros (Ellis and Kuerbis, 1987, 1989) teacher development materials (text, video, and tutorial software) for helping science teachers improve their use of educational technology. Phase two (1986–1989): BSCS designed, developed, tested, and disseminated a staff development model for helping science teachers integrate educational technology into instruction. Phase three (1989–1992): BSCS established Teacher Development Centers to implement theENLIST Micros teacher development materials and staff development model with science teachers throughout the United States.ENLIST Micros has served more than 1500 science teachers in 15 states. Teachers who have participated in the program have improved their knowledge, attitude, and self-efficacy about computer usage and have improved their use of microcomputers in their science courses. Furthermore, as part of the project, BSCS has described the implementation process and has developed recommendations to support improvements in the use of educational technology in science programs.

Changes in Korean Science Teachers' Perceptions of Creativity and Science Teaching After Participating in an Overseas Professional Development Program

This study investigated changes in Korean science teachers' perceptions of creativity and science teaching after participating in an overseas professional development program. Participants were 35 secondary science teachers. Data were collected from open-ended questionnaires and interviews. Results indicated that participants showed a growing awareness that creativity can be expressed by every student; creativity can be enhanced; science has a much wider range of activities that foster creativity; and creativity-centered science teaching can be implemented in Korea. The major elements of the professional program that promoted these perceptual changes included hands-on creativity activities, observation of creativity-centered classrooms, and discussion with other teachers. Follow-up study revealed that their perceptual changes have been reflected in their teaching practices.

Project design factors that affect student perceptions of the success of a science research project

Throughout the United States, various summer science programs for precollege students are conducted with an aim toward increasing the involvement of young people in science. Most of these programs are perceived as successful by teachers and scientists because they involve students in hands-on science activities, improve their scientific skills and confidence, and allow them the opportunity to use science to answer questions and solve problems. The work described here involves a detailed assessment of a summer National Science Foundation (NSF) Young Scholars Program, which was carried out over 2 summers. Student participants were entering 9th and 10th grade. The data used for this assessment included journals kept by teaching assistants, questionnaires administered to the participants and parents, and interviews with the participants. Analysis revealed that students perceived program success differently from teachers and program organizers. Their perception of the success of a program is directly related to whether or not their individual research project met its goals, regardless of other project activities. Designing projects that have a high likelihood of success from this perspective can be complex, but this work identified six variables that must be incorporated appropriately into the design of a project to ensure its success: (1) extent of project structure and who structures the project, faculty or student; (2) project relevance; (3) project flexibility; (4) project background research; (5) tangible results; and (6) project introduction.     

Bringing Dinosaur Science to the Junior Girl Scouts Through a College Service-Learning Project

Undergraduate students in an introductory-level geoscience course successfully designed and conducted a science badge day for the Junior Girl Scouts. With national concerns that girls turn away from science at a young age, a service-learning project was incorporated into a college course with the end result providing a group of girls a positive and fun science-learning experience. A number of science and technology badges exist for the Girl Scouts, yet not many of these badges have been completed because of a lack of confidence the troop leaders have in teaching science and a paucity of scheduled science events for the leaders to take their girls. Junior Girl Scout troops were invited to the Pennsylvania State University Delaware County campus to complete a series of hands-on dinosaur science activities that allowed them to earn the Science in Everyday Life badge. At the conclusion of the badge event, the girls reported a greater interest in science, a desire to learn more science, and a desire to complete additional science-related Girl Scout badges.     

Teaching HCI Design With the Studio Approach

The studio-based method of teaching has been used for almost 100 years to teach product and architecture design. With ever increasing pressure on HCI to teach competence in designing interactive objects, new ways of teaching need to be explored. This article begins with a review of the studio-based teaching concept and how it has been used in architecture, science/engineering, and computer science education. We then present and discuss the evaluation of an HCI design studio course which we created and taught in spring 2002 in the Computer and Information Science Department of the University of Oregon. This course was based on our observations and study of studio courses in the School of Architecture. Finally, we review general issues about studio teaching including the promises and challenges that it presents to widespread acceptance in the computer science curriculum.     

Using Video Games to Support Pre-Service Elementary Teachers Learning of Basic Physics Principles

The purpose of this work is to share our findings in using video gaming technology to facilitate the understanding of basic electromagnetism with pre-service elementary teachers. To this end we explored the impact of using a game called Supercharged! on pre-service teachers’ understanding of electromagnetic concepts compared to students who conducted a more traditional inquiry oriented investigation of the same concepts. This study was a part of a larger design experiment examining the pedagogical potential of Supercharged! the control group learned through a series of guided inquiry methods while the experimental group played Supercharged! during the laboratory sections of the science course. There was significant difference F(2,134) = 4.8, p < 0.05, η² = 0.59 between the control and experimental groups on the gains from pre-to-post assessment with an effect size of d = 0.72. However, while students in the experimental group performed better than their control group peers, they rated their knowledge of the topic lower than the control group (M _post-control = 3.0, M _{post-experiment} = 2.7), leading to further examination of their laboratory journals. Results of this study show that video games can lead to positive learning outcomes, as demonstrated by the increase in test scores from pre- to post-assessment. Additionally, this study also suggests that a complementary approach, in which video games and hands-on activities are integrated, with each activity informing the other, could be a very powerful technique for supporting student scientific understanding. Further, our findings suggest that video game designers should embed meta-cognitive activities such as reflective opportunities into educational video games to provide scaffolds for students and to reinforce that they are engaged in an educational learning experience.     

A survey of pre-service primary teachers' experiences of science in schools

In 1990, a large proportion of third year primary trainee teachers at Victoria College had observed or taught very few or no science lessons during the first two years of their course. The students felt that a lack of content knowledge, a crowded school curriculum, and problems associated with managing resources and equipment, were the main factors contributing to the low level of science being taught in schools. By the end of their third year significantly more students had taught science than after the second year. There was also a change in approach to teaching science with more practical activities being included than previously. The science method unit taught to the students in the third year of their course contributed to this increase. The students considered the hands-on activities in class to have been the most effective aspect of the unit in their preparation for the teaching of primary science.

Minority Preservice Teachers’ Conceptions of Teaching Science: Sources of Science Teaching Strategies

This study explores five minority preservice teachers’ conceptions of teaching science and identifies the sources of their strategies for helping students learn science. Perspectives from the literature on conceptions of teaching science and on the role constructs used to describe and distinguish minority preservice teachers from their mainstream White peers served as the framework to identify minority preservice teachers’ instructional ideas, meanings, and actions for teaching science. Data included drawings, narratives, observations and self-review reports of microteaching, and interviews. A thematic analysis of data revealed that the minority preservice teachers’ conceptions of teaching science were a specific set of beliefs-driven instructional ideas about how science content is linked to home experiences, students’ ideas, hands-on activities, about how science teaching must include group work and not be based solely on textbooks, and about how learning science involves the concept of all students can learn science, and acknowledging and respecting students’ ideas about science. Implications for teacher educators include the need to establish supportive environments within methods courses for minority preservice teachers to express their K-12 experiences and acknowledge and examine how these experiences shape their conceptions of teaching science, and to recognize that minority preservice teachers’ conceptions of teaching science reveal the multiple ways through which they see and envision science instruction.     

Language Use in a Multilingual Class: a Study of the Relation Between Bilingual Students’ Languages and Their Meaning-Making in Science

In this study, we examine how bilingual students in elementary school use their languages and what this means for their meaning-making in science. The class was multilingual with students bilingual in different minority languages and the teacher monolingual in Swedish. The analysis is based on a pragmatic approach and the theory of translanguaging. The science content was electricity, and the teaching involved class instruction and hands-on activities in small groups. The findings of the study are divided into two categories, students’ conversations with the teacher and student’s conversations with each other. Since the class was multilingual, the class instruction was carried out in Swedish. Generally, when the conversations were characterised by an initiation, response and evaluation pattern, the students made meaning of the activities without any language limitations. However, when the students, during whole class instruction, were engaged in conversations where they had to argue, discuss and explain their ideas, their language repertoire in Swedish limited their possibilities to express themselves. During hands-on activities, students with the same minority language worked together and used both of their languages as resources. In some situations, the activities proceeded without any visible language limitations. In other situations, students’ language repertoire limited their possibilities to make meaning of the activities despite being able to use both their languages. What the results mean for designing and conducting science lessons in a multilingual class is discussed.     

Withholding answers during hands-on scientific investigations? Comparing effects on developing students’ scientific knowledge,reasoning, and application

As more concerns have been raised about withholding answers during science teaching, this article argues for a need to detach ‘withholding answers’ from ‘hands-on’ investigation tasks. The present study examined students’ learning of light-related content through three conditions: ‘hands-on’ + no ‘withholding’ (hands-on only: HO), ‘hands-on’ + ‘withholding’ (hands-on investigation with answers withheld: HOW), and no ‘hands-on’ + no ‘withholding’ (direction instruction: DI). Students were assessed in terms of how well they (1) knew the content taught in class; (2) reasoned with the learned content; and (3) applied the learned content to real-life situations. Nine classes of students at 4th and 5th grades, N?=?136 in total, were randomly assigned to one of the three conditions. ANCOVA results showed that students in the hands-on only condition reasoned significantly better than those in the other two conditions. Students in this condition also seemed to know the content fairly better although the advance was not significant. Students in all three conditions did not show a statistically significant difference in their ability to apply the learned content to real-life situations. The findings from this study provide important contributions regarding issues relating to withholding answers during guided scientific inquiry.
