The purpose of this commentary on Hodson and Wong's (2017, this issue) article is to clarify the merits of the expanded family resemblance approach (FRA) to science education, briefly alluded to in their article, and to discuss the implications of this approach relative to the question of demarcation they raise. In clarifying the merits of the…

The "consensus view" on the nature of science (NOS) is now outmoded. To help frame an enduring alternative, one should attend first to the "why" of NOS education. Functional, or civic, scientific literacy is foundational. Acknowledging a need for consumers and citizens to assess the reliability of scientific claims in personal…

The radioactive nature of technetium is discussed using a combination of introductory nuclear physics concepts and empirical trends observed in the chart of the nuclides and the periodic table of the elements. Trends such as the enhanced stability of nucleon pairs, magic numbers, and Mattauch's rule are described. The concepts of nuclear binding…

Evolution is the unifying theory in biological sciences, yet in the United States, a majority of the population holds beliefs that are in conflict with those concepts and therefore are not completely open to considering evolutionary theory. The Gallup poll on evolution, creationism and intelligent design is one of the longest running polls…

Nature of science (NOS) is considered an important aspect of scientific literacy. Despite efforts in guiding school students to develop more adequate NOS views, little is known about the long-term retention of students' post-intervention views. Retention of adequate NOS views is needed for functioning as scientifically literate citizens. Moreover,…

The present study aimed to determine the impact of argument-based laboratory method on the scientific process skills of pre-service primary school teachers and their views on the nature of science. The study was designed based on the pretest-posttest quasi-experimental method and conducted with 64 sophomore pre-service primary school teachers (37…

Helping students understand that the scientific community's claims change through time, sometimes radically, allows them to develop a well-grounded sense of the "nature of science." Learning to reason about how scientific claims come to be accepted, and later refuted, is important for understanding the tentative nature of scientific…

Both accurate monitoring and adequate control are crucial for effective self-regulation when learning from problem-solving tasks. Prior research has shown that self-regulated learning is especially harmful for low prior knowledge students, given their difficulties with accurate monitoring and control decisions. Although many studies have indicated…

To improve the teaching and learning materials for a curriculum it is important to incorporate the findings from educational research. In light of this, we present creative exercises and experiments to elicit, confront and resolve misconceptions in geometrical optics. Since ray diagrams can be both the cause and the solution for many…

The purpose of this study was to reveal beliefs of prospective teachers about "science" and "science history." The qualitative research approach was employed in the study. The study group consisted of 150 prospective teachers. A form developed by the researcher was used for data collection. The form consisted of open-ended…

Electrochemistry is primarily taught in first-year undergraduate courses through batteries; this lab focuses instead on corrosion to apply electrochemical concepts of electrolytes, standard reduction potentials, galvanic cells, and other chemistry concepts including Le Chatelier's Principle and Henry's Law. Students investigate galvanic corrosion…

Many educators and educational institutions worldwide have agreed that the main goal of science education is to produce a scientifically literate community. Science teachers are key to the achievement of scientific literacy at all levels of education because of the essential role they play in preparing scientifically literate individuals. Studies…

Designing and conducting sound and informative experiments is an important aspect of inquiry learning. Students, however, often design experiments that do not allow them to reach conclusions. Considering the difficulties students experience with the process of designing experiments, additional guidance in the form of an Experiment Design Tool…

"How does an aircraft fly?" is one of the most frequently asked science questions by young pupils. The lift on airplane wings also makes a great example of the application of the Bernoulli principle while teaching fluid mechanics in introductory physics and engineering courses. The topic is of great interest and is therefore covered in…

The ability of certain organometallic reagents to react via 1,2- or 1,4-addition to an a,ß-unsaturated ketone is a fundamental example of regioselectivity at the second-year undergraduate organic level. The following two experiments were designed to demonstrate this preference by exploiting carvone as an inexpensive chiral, nonracemic substrate.…
