Did not use some or all of the data provided in the problem. Teacher can explain the facts of biology or the laws of physics in the form of stories. A. Procedures are tasks that are carried out automatically or intentionally during problem solving (Alexander and Judy, 1988). Our findings of improved student learning with SOLVEIT (Kim et al., 2015) are consistent with the research of others that shows scaffolding can improve student problem solving (Lin and Lehman, 1999; Belland, 2010; Singh and Haileselassie, 2010). Of all the relevant declarative knowledge for a particular problem, which pieces do students typically access and which pieces are typically overlooked? We have used the theoretical framework of domain-specific problem solving to investigate student cognition during problem solving of multiple-choice biology problems about ecology, evolution, and systems biology. Despite this limitation, we were able to identify a range of problem-solving procedures and errors that inform teaching and learning. It illustrates that although the scientific method is often presented as a didactic list of steps, there is no one fixed sequence of events that occurs in order for important scientific discoveries to be made. As explained in the Introduction, the strongest problem-solving approaches stem from a relatively complete and well-organized knowledge base within a domain (Chase and Simon, 1973; Chi et al., 1981; Pressley et al., 1987; Alexander and Judy, 1998). Asking a Question provides another illustration of students practicing metacognition. We also identified domain-general and domain-specific errors made by students during problem solving. We trained students to produce written descriptions of how they solved the problem, and this allowed us to systematically investigate their problem-solving procedures. After watching this video students will be able to: Funding provided by the Singapore University of Technology and Design (SUTD), Developed by the Teaching and Learning Laboratory (TLL) at MIT for SUTD, Scientific Process Instructor Guide (PDF). Having assigned student problem-solving procedures to categories, we determined whether the category aligned best with domain-general or domain-specific problem solving. They can be highly specific to the domain, such as analyzing the evolutionary relationships represented by a phylogenetic tree, or general and applicable to problems across many domains, such as paraphrasing a problem-solving prompt (Pressley et al., 1987, 1989; Alexander and Judy, 1988). Frequency of each problem-solving procedure for lower-order and higher-order problems. Predicting was described by Crowe and colleagues (2008). These procedures also could be used in other domains. Disregarding Evidence occurred when students’ failed to indicate use of evidence. We propose that our categorization scheme and the theoretical framework of domain-specific problem solving should be applied for further study of biology problem solving. As an early step in the written think-aloud, predicted what they expected the answer to be (i.e., what multiple-choice option they were looking for). More specifically, we focus on procedural knowledge. Massachusetts Institute of Technology. Example #1 1. We selected examples of good documentation and poor documentation and published these anonymously on the online course-management system. Knowledge is your reward. Download files for later. Made for sharing. Students’ written think-alouds describing their processes for solving the stickleback problem. To what extent do students use domain-general and domain-specific procedures when solving lower-order versus higher-order problems? Explicit modeling of domain-specific procedures would be eye-opening for students, who tend to think that studying for recognition is sufficient, particularly for multiple-choice assessment. When students asked a question, they pointed out that they needed to know some specific piece of content that they did not know yet. TABLE 6. Making Incorrect Assumptions was identified when students made faulty assumptions about the information provided in the prompt. We wrote 16 multiple-choice problems to include in this study. Domain-specific problem solving has its origins in information-processing theory (IPT; Newell and Simon, 1972). However, problem solving is not intuitive to students, and these skills typically are not explicitly taught in the classroom (Nehm, 2010; Hoskinson et al., 2013). All three think-alouds were generated in response to the stickleback problem; pseudonyms are used to protect students’ identities (Figure 1). We then repeated these steps for additional think-alouds while still together. In solving domain-specific problems, at some point, the solver has to understand the particulars of a domain to reach a legitimate solution (reviewed in Pressley et al., 1987; Bassok and Novick, 2012). Domain-specific problem-solving research recognizes three types of knowledge that contribute to expertise. Some teachers present the whole concept as a story while some others use a story to open and end the session. With more than 2,400 courses available, OCW is delivering on the promise of open sharing of knowledge. Students’ problem-solving procedures while solving multiple-choice biology problems. She started by thinking about the type of answer she was looking for (Predicting). No enrollment or registration. Different types of problem-solving processes are indicated with different font types: Domain-general problem-solving steps: blue lowercase font; domain-specific problem-solving steps: blue uppercase font, hybrid problem-solving steps: blue italics; domain-general errors: orange lowercase font; domain-specific errors: orange uppercase font. In addition to group case studies, the instructor assessed student learning via individual exams. A color scale is used to represent the frequency of each type of error, with the lowest-frequency errors shown in dark blue, moderate-frequency errors shown in white, and high-frequency errors shown in dark red. Procedural knowledge represents the how-to knowledge that is required to carry out domain-specific tasks. When students corrected, they identified incorrect thinking they had displayed earlier in their written think-aloud and mentioned the correct way of thinking about the problem. However, we ARE interested in teaching students skills that are applicable to solving most types of problems, giving students an opportunity to practice these skills, and assessing whether or not they are improving their problem-solving abilities. Problem-solving starts with identifying the issue. However, for this paper, we use these terms to describe knowledge of biology, not metacognitive knowledge. Researchers and practitioners also need to discover how students develop the ability to use scientific practices. The procedures are categorized as domain-general, hybrid, and domain-specific. In the written think-aloud, students are asked to write, rather than say aloud, what they are thinking as they solve a problem. Retrieved basic facts or concepts from class, notes, or the textbook (i.e., declarative knowledge). Supplemental Resources To train students to perform a written think-aloud, the course instructor modeled the think-aloud in class. (E) could also make sense but I think there is enough information to make a decision. Problem Solving Skills Examples. B is incorrect because Atlantic eels should show some resistance since the Atlantic eel have developed in the presence of krait toxin. We also considered the frequency of problem-solving errors made by students solving lower-order and higher-order problems. It is even more concerning that students’ use of Recognizing is nearly four times more prevalent in lower-order problems than higher-order problems and that overall domain-general procedures are more prevalent in lower-order problems (Table 5A).
