This study investigated the effectiveness of the orientation, identify, discussion, decision, and engage in behavior (OIDDE) learning model in enhancing biology learning outcomes, critical thinking, ethical attitudes, and engagement among high school students in Indonesia. Employing a quasi-experimental design with pre- and post-tests, the…

The purpose of this paper was to give a demonstration of the primary materials and methods we used in learning communities (LCs) for biology students. The LCs were based on the performance pyramid theoretical structure. The objectives were to show the pedagogical links biological and mathematical concepts through cocurricular projects; assess…

The Expectancy-Value model has been extensively used to understand students' achievement motivation. However, recent studies propose the inclusion of cost as a separate construct from values, leading to the development of the Expectancy-Value-Cost model. This study aimed to adapt Kosovich et al.'s ("The Journal of Early Adolescence", 35,…

Understanding scientific models and practicing scientific modeling have been emphasized and advocated in science learning. Although teachers have been perceived as shaping their students' understanding of the nature of science, they have been recognized for their lack of understanding of scientific models. This study explores middle school science…

The processes of mitosis and meiosis are oft-cited and long-standing examples of concepts that are difficult for students to learn and understand. While there are many examples in the literature of "how-to-do-it," innovative instructional approaches for teaching mitosis and meiosis, publications that include measurement of learning gains…

The gender gap continues to exist in physics education. The author examines the gender-related differences in the relations and strengths among personal epistemologies, motivation, and achievement in physics among Turkish high school students. Established questionnaires were used to identify students' personal epistemologies, motivations and…

Research points to the important role achievement emotions play in academic performance and career choices, yet few studies have examined achievement emotions in non-Western contexts. The current study extends this research base by examining students' achievement emotions among 103 eleventh-grade high school chemistry students in China. Using…

Metacognitive ability is enormously important for improving students' learning performance. However, overconfidence bias may hinder students' metacognition abilities. Therefore, in this study, we conducted an intervention to reduce or debias overconfidence among students using the KAAR (knowledge, awareness, action, and reflection) model. Ninety…

We investigated students' perceptions related to psychological constructs in their science classes and the influence of these perceptions on their science identification and science career goals. Participants included 575 middle school students from two countries (334 students in the U.S. and 241 students in Iceland). Students completed a…

A concept of major importance in human electrophysiology studies is the process by which activation of an excitable cell results in a rapid rise and fall of the electrical membrane potential, the so-called action potential. Hodgkin and Huxley proposed a model to explain the ionic mechanisms underlying the formation of action potentials. However,…

The aim of this study is to determine the extent at which students' computational thinking (CT) skills are explained by certain variables. To this end, the existence of explanatory and predictive relationships between students' CT skills and the variables in question has been examined and Structural Equation Model was employed for building a model…

The purpose of the present study was to examine the validity of modeling science achievement in terms of 3 social psychological variables (school connectedness, science attitude, and active learning) and 2 self-perception variables (self-confidence and science value). Two models were tested: full mediation and partial mediation. In the…

Purpose: The difficulties higher education institutions in developing countries face in finding adequate and relevant onsite student internship opportunities make a case for online internships. The purpose of this paper is to present an online internship model, developed over a two-year period, which challenged students to engage in…

This research identifies a problem of practice with standardized science test scores declining over the last eight years. The Sea Turtle Elementary School for the Creative Arts (STESCA; pseudonym) schedule allowed 150 minutes per week for science instruction, compared with 450 minutes per week for mathematics instruction. Science instruction has…

Our short-term longitudinal study explored undergraduate students' experiences with performing authentic science practices in the classroom in relation to their science achievement and course grades. In addition, classroom experiences (felt recognition as a scientist and perceived classroom climate) and changes over a 10-week academic term in STEM…
