This research presents the investigation of physics students' and physics faculty members' professional development and a design methodology via which we could best support them in their professional development. In particular, the first part of this dissertation will focus on undergraduate upper-division physics students' conceptual learning and…

In light of extensive research demonstrating widespread misconceptions about electricity, this paper describes a learning study that targeted the most likely source of difficulty--failure of middle school pupils to develop a mental model that serves as a bridge between static and current electricity. During the intervention, pupils first envision…

This study developed a web-based multimedia assessment system (WMA system) and applied it to science laboratory instruction. The goal was to improve students' knowledge acquisition under science laboratory instruction. The developed system enabled learners to perform self-assessments by responding to multimedia technology test items online. The…

According to the views of social constructivism, learning takes place when individuals engage socially to talk about and act on shared problems or interests. In recent years, this approach has been very popular for the teaching and learning of mathematics in primary and secondary education. On the contrary, in tertiary education, it seems that…

The purpose of this study was to determine the effect of Design Based Science Education (DBSE) applications on the perceptions of science teacher candidates about engineering education and engineers. In the quantitative part of the study in which the mixed method was involved, a semi-experimental design with single group pre-test post-test was…

A low-cost and simple setup to measure the densities of liquids is introduced herein. The results and reliability of this setup were evaluated for pure liquids, water-ethanol binary mixtures, and aqueous NaCl solutions. The constructed densitometer provided density values with acceptable relative errors (less than ±3.0%), which were compared to…

Past studies on the differential effects of active learning based on students' prior preparation and knowledge have been mixed. The purpose of the present study was to ask whether students with different levels of prior preparation responded differently to laboratory courses in which a guided-inquiry module was implemented. In the first study, we…

Despite the inherent potential of cooperative learning, there has been very little research into its effectiveness in middle school laboratory classes. This study focuses on an empirical comparison between cooperative learning and individual learning in the school science laboratory, evaluating the quality of learning and the students' attitudes.…

Allelopathy plays crucial roles in invasive plant viability and agricultural production systems. However, there is no well-established hands-on learning activity to teach the concept of allelopathy. Nor is there an activity which allows students to gain knowledge about glucosinolates and their corresponding enzyme, myrosinase, which are present in…

The main goals of the current study are (1) college students' cyberloafing behaviors during a lab session, (2) reasons that students cyberloaf, and (3) possible solutions to prevent this behavior from the students' perspectives. A total of 184 students registered for lab hours at a public university in Turkey were recruited to participate in this…

A Sonogashira experiment was transformed into a problem-based learning platform for third-year undergraduate students. Given a target that could be synthesized in a single step, students worked in groups to investigate which method was the best for large-scale production. Through this practical scenario, students learn to conduct a literature…

The real power of calculus is revealed when it is applied to actual physical problems. In this paper, we present a calculus inspired physics experiment suitable for high school and undergraduate programs. A model for the theory of the terminal velocity of a falling body subject to a resistive force is developed and its validity tested in an…

The use of science kits is a growing trend in India. The kits provide equipments, apparatus and chemicals in the form of a moving laboratory to use in science classes. This research paper highlights the issues and challenges faced by the Government school teachers of Delhi in India while using science kits during teaching-learning process at upper…

This paper examines an experiment conducted at a 2-year college with non-majors. The Immediate Feedback Assessment Technique (IFAT) is a cross between a lottery scratch ticket and a scantron form which was designed to replace scantrons (EpsteinEducation.com). Using the IFAT in an unconventional way (reviewing class material), we expected to find…

The purpose of this study was to investigate the meanings assigned by pre-service teachers to the wastepaper basket and waste (crumpled) papers in their drawings of a scientist. The study was carried out with 220 pre-service teachers during the 2015-2016 academic years. A phenomenological research method was used. First, the pre-service teachers…
