Elements of instructional design such as explicitly stated objectives, reviews, examples, questions, and feedback were incorporated into the laboratory manual and instruction for a unit on kinetics in a college laboratory course. This treatment (high structure) was given to five sections of students (N = 109), while a laboratory manual and instructions that emphasized informational content without the use of these design strategies (low structure) was given to another five sections (N = 108) taught by the same instructors. The students receiving the additional structure scored significantly higher on a quiz, took less time to solve a set of laboratory problems, and felt more satisfied with the instruction provided. There were no differences between groups in their comfort with the knowledge acquired. There were no interactions with performance outcomes, but several occurred for attitudes, treatments, and personality measures. The more conforming the students, the more satisfied they were with the instruction in the high-structured group and the less they liked it in the low-structured group. The more motivated the students, the more they liked the instruction in the high-structure treatment, and even more in the low-structure group. There was also a complex interaction among treatment, anxiety, ability, and treatment satisfaction. 相似文献

This study examines the influence of laboratory instruction that engages students in a wide range of the practices of science on Turkish high-school students’ chemistry learning. In this mixed methods study, student learning in two different laboratory settings was compared, one that featured an instruction that engaged students in a wide range of disciplinary practices (through Argument-driven Inquiry – ADI) and similar laboratories in which a more traditional Structured Inquiry (SI) approach was employed. The data sources included a Chemistry Concept test, an Argumentative Writing Assessment, and Semi-structured interviews. After seven weeks of chemistry instruction, students experiencing ADI instruction scored higher on the Chemistry Concept test and the Argumentative Writing Assessment than students experiencing SI instruction. Furthermore, girls who experienced ADI instruction scored higher on the assessments than their majority peers in the same class. The results suggest that Turkish students can substantially improve their chemistry proficiency if they have an opportunity to engage in instruction featuring a broad array of the practices of science. 相似文献

There has been a long tradition of laboratory activities associated with science instruction. Despite constructivists' claims advocating open-ended inquiry and mentoring, little is known about what students are thinking when engaged in laboratory activities. Laboratory learning as a process of cognitive apprenticeship has been proposed as a metaphor to guide teacher practice and student learning. The viability of cognitive apprenticeship for learning science in school is discussed in relation to findings from an investigation of a research project involving high school students working in a university chemical engineering laboratory under the mentorship of a university-based scientist. Data from a variety of techniques were analyzed in an interpretive style. We found that the students were empowered to seek empirically viable knowledge claims as they became independent researchers. However, we argue that caution needs to be exercised before advocating open-ended inquiry as a general model for laboratory learning without additional studies in different contexts. © 1996 John Wiley & Sons, Inc. 相似文献

As information professionals, engineering librarians have the primary responsibilities of providing access to engineering information resources and giving instruction in how to use these resources. In the case of undergraduate engineering students, this extends to building their information literacy skills, an important component in helping them become lifelong learners; to be curious and independent, and to take greater responsibility for their own learning. The challenge in building information literacy in engineering students is to acquaint the students with the array of library resources available to them and to help them intelligently navigate the systems that contain the information. Too often, information literacy instruction is presented as a set of procedures for locating a hypothetical resource in the library. However, students are not interested in finding some resource randomly chosen as an example; they want to find resources that they perceive as being important and useful. During the 2005–2006 academic year, the engineering librarians at Drexel University took this into consideration and employed a new methodology for information literacy instruction: combining an online tutorial covering basic library skills with face-to-face consultations between student design teams and the engineering librarians. By utilizing varied instruction techniques aimed at different learning styles, with a strong active learning component delivered at the student's point of need—when they have a concrete, perceived information need—information literacy instruction can be improved so that engineering students retain more and develop lifelong learning skills. 相似文献

Metacognition can be described as an internal conversation that seeks to answer the questions, ‘how much do I really know about what I am learning’ and, ‘how am I monitoring what I am learning?’ Metacognitive regulation skills are critical to meaningful learning because they facilitate the abilities to recognize the times when one's current level of understanding is insufficient and to identify the needs for closing the gap in understanding. This research explored how using the Science Writing Heuristic (SWH) as an instructional approach in a laboratory classroom affected students’ practice of metacognitive skills while solving open-ended laboratory problems. Within our qualitative research design, results demonstrate that students in the SWH environment, compared to non-SWH students, used metacognitive strategies to a different degree and to a different depth when solving open-ended laboratory problems. As students engaged in higher levels of metacognitive regulation, peer collaboration became a prominent path for supporting the use of metacognitive strategies. Students claimed that the structure of the SWH weekly laboratory experiments improved their ability to solve open-ended lab problems. Results from this study suggest that using instruction that encourages practice of metacognitive strategies can improve students’ use of these strategies. 相似文献

Globally, many people spend most of their time interacting with the products of engineering design as they wear clothes, drink clean water, use transportation systems, and more. Given the omnipresence of engineering design, whose material results are felt daily in people’s lives, it seems especially important that students learn to recognize and question how certain designs promote the welfare and interests of some while remaining inaccessible to others. In this article, we outline a vision for critical literacy instruction in engineering that simultaneously incorporates and challenges professional standards. We—an associate professor of literacy, an engineer, and a teacher at an engineering-focused high school—illustrate how critical literacy instruction might be enacted in the context of engineering design instruction in high schools. We describe how critical literacy can complement disciplinary literacy instruction in engineering as students use critically-focused, disciplinary lenses to move toward social justice. 相似文献

This case study explores young children’s understanding and application of the concept of volume through the practices of engineering design in a STEM activity. STEM stands for science, technology, engineering, and mathematics. However, engineering stands out as a challenging area to implement. In addition, most early engineering education research centers on curriculum and instruction rather than students’ understanding and application of models and content knowledge to a design project (Johri and Olds, Journal of Engineering Education, 100(1):151–185, 2011). For this study, we created a play-based STEM activity which helps students understand and apply the concept of volume in creating clay boats through the practices of engineering design. Three students voluntarily participated in this study. Data sources included interviews, photocopies of boats, and observation field notes which were analyzed using a comprehensive cross-case analysis. Findings indicate that the common pattern is rather intuitive when students define engineering problems using different criteria. Also, students’ solutions to engineering problems are associated with their experiential ideas of reality. How students express their understanding of volume is correlated to the way of their structuring volume. Lastly, students understand the concept of volume gradually while going through the practices of engineering design. Implications are discussed in terms of how engineering education contributes to students’ understanding of volume. 相似文献

The present project embarked on an educational intervention, consisting of a series of online ethics learning modules, to
aid international graduate students in overcoming the acculturation barriers to understanding and inculcating normative ethical
obligations associated with engineering practice and research in the United States. A fundamental initial step in the process
of helping international, as well as domestic, engineering graduate students embrace ethical obligations is to provide clear
instruction on fundamental engineering ethical principles and values relevant in the United States. Most institutes of higher
education do not have a cohesive approach to basic graduate engineering ethics instruction, much less materials that have
been calibrated for international students (National Science Foundation, , 2009). Herein the authors describe our instructional intervention, as well as to document the development, design, and assessment
of the learning modules intended to provide students with a framework for learning ethical precepts and applying them in the
engineering field. Think-Aloud Protocol and Cognitive Task Analysis results were used to improve the content modules and learning
experience. Initial pilot findings indicate that the content modules increased student knowledge acquisition compared to pre-test
performance, indicating a step-forward in the formulation of a useful learning tool for graduate engineering ethics instruction. 相似文献

Learning Environment, Attitudes and Achievement among Middle-school Science Students Using Inquiry-based Laboratory Activities 总被引：1，自引：0，他引：1
This study compared inquiry and non-inquiry laboratory teaching in terms of students’ perceptions of the classroom learning
environment, attitudes toward science, and achievement among middle-school physical science students. Learning environment
and attitude scales were found to be valid and related to each other for a sample of 1,434 students in 71 classes. For a subsample
of 165 students in 8 classes, inquiry instruction promoted more student cohesiveness than non-inquiry instruction (effect
size of one-third of a standard deviation), and inquiry-based laboratory activities were found to be differentially effective
for male and female students. 相似文献
