Scientific misconceptions are commonly held beliefs about science that have no basis in actual scientific fact. Scientific misconceptions can also refer to preconceived notions based on religious and/or cultural influences. Many scientific misconceptions occur because of faulty teaching styles and the sometimes distancing nature of true scientific texts. Because students' prior knowledge and misconceptions are important factors for learning science, science teachers should be able to identify and address these conceptions.

Types

Misconceptions (a.k.a. alternative conceptions, alternative frameworks, etc.) are a key issue from constructivism in science education, a major theoretical perspective informing science teaching. [1] A scientific misconception is a false or incorrect understanding of a scientific concept or principle, often resulting from oversimplifications, inaccurate information, or the misapplication of intuitive knowledge. Misconceptions can arise due to a variety of factors, such as personal experiences, cultural beliefs, or the way information is presented in educational settings. Addressing scientific misconceptions is crucial for developing a more accurate understanding of the natural world and improving scientific literacy. [2] In general, scientific misconceptions have their foundations in a few "intuitive knowledge domains, including folkmechanics (object boundaries and movements), folkbiology (biological species' configurations and relationships), and folkpsychology (interactive agents and goal-directed behavior)", [3] that enable humans to interact effectively with the world in which they evolved. That these folksciences do not map accurately onto modern scientific theory is not unexpected. A second major source of scientific misconceptions are educational misconceptions, which are induced and reinforced during the course of instruction (in formal education).

There has been extensive research into students' informal ideas about science topics, and studies have suggested reported misconceptions vary considerably in terms of properties such as coherence, stability, context-dependence, range of application etc. [4] Misconceptions can be broken down into five basic categories: [5]

  1. preconceived notions
  2. nonscientific beliefs
  3. conceptual misunderstandings
  4. vernacular misconceptions
  5. factual misconceptions

Preconceived notions are thinking about a concept in only one way. Specially heat, gravity, and energy. Once a person knows how something works it is difficult to imagine it working a different way. Nonscientific beliefs are beliefs learned outside of scientific evidence. For example, one's beliefs about the history of world based on the bible. Conceptual misunderstandings are ideas about what one thinks they understand based on their personal experiences or what they may have heard. One does not fully grasp the concept and understand it. Vernacular misconceptions happen when one word has two completely different meanings, specially in regard to science and everyday life. Factual misconceptions are ideas or beliefs that are learned at a young age but are actually incorrect.

While most student misconceptions go unrecognized, there has been an informal effort to identify errors and misconceptions present in textbooks. [6]

Identifying student misconceptions

In the context of Socratic instruction, student misconceptions are identified and addressed through a process of questioning and listening. A number of strategies have been employed to understand what students are thinking prior, or in response, to instruction. These strategies include various forms of "real type" feedback, which can involve the use of colored cards or electronic survey systems (clickers). [7] Another approach is typified by the strategy known as just-in-time teaching. [8] [9] Here students are asked various questions prior to class, the instructor uses these responses to adapt his or her teaching to the students' prior knowledge and misconceptions.

Finally, there is a more research-intensive approach that involves interviewing students for the purpose of generating the items that will make up a concept inventory or other forms of diagnostic instruments. [10] Concept inventories require intensive validation efforts. Perhaps the most influential of these concept inventories to date has been the Force Concept Inventory (FCI). [11] [12] Concept inventories can be particularly helpful in identifying difficult ideas that serve as a barrier to effective instruction. [13] Concept inventories in natural selection [14] [15] [16] and basic biology [17] have been developed.

While not all the published diagnostic instruments have been developed as carefully as some concept inventories, some two-tier diagnostic instruments (which offer multiple choice distractors informed by misconceptions research, and then ask learners to give reasons for their choices) have been through rigorous development. [18] In identifying students' misconceptions, first teachers can identify their preconceptions. [19] "Teachers need to know students' initial and developing conceptions. Students need to have their initial ideas brought to a conscious level." [20] However, teachers' ability to diagnose misconceptions needs to be improved. When confronted with misconceptions about evolution, they only diagnose approximately half of these misconceptions. [21] Thus, another approach for identifying misconceptions could be that not only teachers do it but the students themselves. With the help of lists with common misconceptions and examples, students can identify their own misconceptions and become metacognitively aware of these. [22]

Addressing student misconceptions

A number of lines of evidence suggest that the recognition and revision of student misconceptions involves active, rather than passive, involvement with the material. A common approach to instruction involves meta-cognition, that is to encourage students to think about their thinking about a particular problem. In part this approach requires students to verbalize, defend and reformulate their understanding. Recognizing the realities of the modern classroom, a number of variations have been introduced. These include Eric Mazur's peer instruction, as well as various tutorials in physics. [23] Using a metacognitive approach, researchers have also found that making students metacognitively aware of their own intuitive conceptions through a self-assessment and supporting them in self-regulating their intuitive conceptions in scientific contexts enhances students' conceptual understanding. [22] Scientific inquiry is another technique that provides an active engagement opportunity for students and incorporates metacognition and critical thinking.

Success with inquiry-based learning activities relies on a deep foundation of factual knowledge. Students then use observation, imagination, and reasoning about scientific phenomena they are studying to organize knowledge within a conceptual framework. [24] [25] The teacher monitors the changing concepts of the students through formative assessment as the instruction proceeds. Beginning inquiry activities should develop from simple concrete examples to more abstract. [25] As students progress through inquiry, opportunities should be included for students to generate, ask, and discuss challenging questions. According to Magnusson and Palincsan, [26] teachers should allow multiple cycles of investigation where students can ask the same questions as their understanding of the concept matures. Through strategies that apply formative assessment of student learning and adjust accordingly, teachers can help redirect scientific misconceptions. Research has shown that science teachers have a wide repertoire to deal with misconceptions and report a variety of ways to respond to students' alternative conceptions, e.g., attempting to induce a cognitive conflict using analogies, requesting an elaboration of the conception, referencing specific flaws in reasoning, or offering a parallel between the student's conception and a historical theory. However, approximately half of the teachers do not address students' misconceptions, but instead agree with them, respond scientifically incorrect, or formulate the correct scientific explanation themselves without addressing the specific student conception.

A teaching method is a set of principles and methods used by teachers to enable student learning. These strategies are determined partly by the subject matter to be taught, partly by the relative expertise of the learners, and partly by constraints caused by the learning environment. For a particular teaching method to be appropriate and efficient it has to take into account the learner, the nature of the subject matter, and the type of learning it is supposed to bring about.

<span class="mw-page-title-main">Science education</span> Teaching and learning of science to non-scientists within the general public

Science education is the teaching and learning of science to school children, college students, or adults within the general public. The field of science education includes work in science content, science process, some social science, and some teaching pedagogy. The standards for science education provide expectations for the development of understanding for students through the entire course of their K-12 education and beyond. The traditional subjects included in the standards are physical, life, earth, space, and human sciences.

Social constructivism is a sociological theory of knowledge according to which human development is socially situated, and knowledge is constructed through interaction with others. Like social constructionism, social constructivism states that people work together to actively construct artifacts. But while social constructivism focuses on cognition, social constructionism focuses on the making of social reality.

Instructional scaffolding is the support given to a student by an instructor throughout the learning process. This support is specifically tailored to each student; this instructional approach allows students to experience student-centered learning, which tends to facilitate more efficient learning than teacher-centered learning. This learning process promotes a deeper level of learning than many other common teaching strategies.

<span class="mw-page-title-main">Active learning</span> Educational technique

Active learning is "a method of learning in which students are actively or experientially involved in the learning process and where there are different levels of active learning, depending on student involvement." Bonwell & Eison (1991) states that "students participate [in active learning] when they are doing something besides passively listening." According to Hanson and Moser (2003) using active teaching techniques in the classroom can create better academic outcomes for students. Scheyvens, Griffin, Jocoy, Liu, & Bradford (2008) further noted that "by utilizing learning strategies that can include small-group work, role-play and simulations, data collection and analysis, active learning is purported to increase student interest and motivation and to build students ‘critical thinking, problem-solving and social skills". In a report from the Association for the Study of Higher Education, authors discuss a variety of methodologies for promoting active learning. They cite literature that indicates students must do more than just listen in order to learn. They must read, write, discuss, and be engaged in solving problems. This process relates to the three learning domains referred to as knowledge, skills and attitudes (KSA). This taxonomy of learning behaviors can be thought of as "the goals of the learning process." In particular, students must engage in such higher-order thinking tasks as analysis, synthesis, and evaluation.

A concept inventory is a criterion-referenced test designed to help determine whether a student has an accurate working knowledge of a specific set of concepts. Historically, concept inventories have been in the form of multiple-choice tests in order to aid interpretability and facilitate administration in large classes. Unlike a typical, teacher-authored multiple-choice test, questions and response choices on concept inventories are the subject of extensive research. The aims of the research include ascertaining (a) the range of what individuals think a particular question is asking and (b) the most common responses to the questions. Concept inventories are evaluated to ensure test reliability and validity. In its final form, each question includes one correct answer and several distractors.

Learning styles refer to a range of theories that aim to account for differences in individuals' learning. Although there is ample evidence that individuals express personal preferences on how they prefer to receive information, few studies have found validity in using learning styles in education. Many theories share the proposition that humans can be classified according to their "style" of learning, but differ on how the proposed styles should be defined, categorized and assessed. A common concept is that individuals differ in how they learn.

<span class="mw-page-title-main">Metacognition</span> Self-awareness about thinking, higher-order thinking skills

Metacognition is an awareness of one's thought processes and an understanding of the patterns behind them. The term comes from the root word meta, meaning "beyond", or "on top of". Metacognition can take many forms, such as reflecting on one's ways of thinking, and knowing when and how oneself and others use particular strategies for problem-solving. There are generally two components of metacognition: (1) cognitive conceptions and (2) cognitive regulation system. Research has shown that both components of metacognition play key roles in metaconceptual knowledge and learning. Metamemory, defined as knowing about memory and mnemonic strategies, is an important aspect of metacognition.

<span class="mw-page-title-main">Formative assessment</span> Method in education

Formative assessment, formative evaluation, formative feedback, or assessment for learning, including diagnostic testing, is a range of formal and informal assessment procedures conducted by teachers during the learning process in order to modify teaching and learning activities to improve student attainment. The goal of a formative assessment is to monitor student learning to provide ongoing feedback that can help students identify their strengths and weaknesses and target areas that need work. It also helps faculty recognize where students are struggling and address problems immediately. It typically involves qualitative feedback for both student and teacher that focuses on the details of content and performance. It is commonly contrasted with summative assessment, which seeks to monitor educational outcomes, often for purposes of external accountability.

Inquiry-based learning is a form of active learning that starts by posing questions, problems or scenarios. It contrasts with traditional education, which generally relies on the teacher presenting facts and their knowledge about the subject. Inquiry-based learning is often assisted by a facilitator rather than a lecturer. Inquirers will identify and research issues and questions to develop knowledge or solutions. Inquiry-based learning includes problem-based learning, and is generally used in small-scale investigations and projects, as well as research. The inquiry-based instruction is principally very closely related to the development and practice of thinking and problem-solving skills.

Conceptual change is the process whereby concepts and relationships between them change over the course of an individual person's lifetime or over the course of history. Research in four different fields – cognitive psychology, cognitive developmental psychology, science education, and history and philosophy of science - has sought to understand this process. Indeed, the convergence of these four fields, in their effort to understand how concepts change in content and organization, has led to the emergence of an interdisciplinary sub-field in its own right. This sub-field is referred to as "conceptual change" research.

Just-in-time teaching is a pedagogical strategy that uses feedback between classroom activities and work that students do at home, in preparation for the classroom meeting. The goals are to increase learning during classroom time, to enhance student motivation, to encourage students to prepare for class, and to allow the instructor to fine-tune the classroom activities to best meet students' needs. This should not be confused with just-in-time learning, which itself focuses on immediate connections between learners and the content that is needed at that moment.

Concept-Oriented Reading Instruction (CORI) was developed in 1993 by Dr. John T. Guthrie with a team of elementary teachers and graduate students. The project designed and implemented a framework of conceptually oriented reading instruction to improve students' amount and breadth of reading, intrinsic motivations for reading, and strategies of search and comprehension. The framework emphasized five phases of reading instruction in a content domain: observing and personalizing, searching and retrieving, comprehending and integrating, communicating to others, and interacting with peers to construct meaning. CORI instruction was contrasted to experience-based teaching and strategy instruction in terms of its support for motivational and cognitive development.

Constructivism has been considered as a dominant paradigm, or research programme, in the field of science education since the 1980s. The term constructivism is widely used in many fields, and not always with quite the same intention. This entry offers an account of how constructivism is most commonly understood in science education.

Physics education research (PER) is a form of discipline-based education research specifically related to the study of the teaching and learning of physics, often with the aim of improving the effectiveness of student learning. PER draws from other disciplines, such as sociology, cognitive science, education and linguistics, and complements them by reflecting the disciplinary knowledge and practices of physics. Approximately eighty-five institutions in the United States conduct research in science and physics education.

The Cognitive Theory of Inquiry Teaching, also referred to as the Cognitive Theory of Interactive Teaching, was developed by Allan Collins and Albert L. Stevens. Allan Collins was a chief scientist at Bolt Beranek and Newman Inc., a research firm in Cambridge Massachusetts. He is also a specialist in the field of cognitive science and human semantic processing. Albert L. Stevens was a senior scientist at Bolt Beranek and Newman Inc. He was also director of the company's Artificial Intelligence, Education Technology and Training Systems Division. He is also a specialist in cognitive science. The Cognitive Theory of Inquiry Teaching according to Collins and Stevens (1981) requires the learner to construct theories and principles through dialogue, the teaching of self-questioning techniques and the teaching of metacognitive or self-monitoring skills, all with the intent of clarifying misconceptions so the theory or principle is well articulated and developed. The essence of the cognitive theory of Inquiry teaching is that of developing students' metacognitive skills. Inquiry teaching deliberately attempts to develop these stills through instruction.
