The aim of this research is to examine the effects of laboratory activities based on the predict-observe-explain (POE) strategy on the understanding of photosynthesis and respiration concepts of pre-service science teachers, and their attitudes towards biology science and course and biology laboratory. Pre- and post-test designs with an…

The goals of the study were as follows: i) to design an active science learning activity on stoichiometry for grade 10 students, ii) to evaluate the academic achievement of grade 10 students after receiving an active science learning activity on stoichiometry, and iii) to investigate the perspectives of grade 10 students regarding an active…

This research integrates context-based learning and modelling. It presents a teaching-learning sequence (TLS) about the dissolution of gases in liquids using carbonated drinks as the context. The impact of the TLS is analysed in a longitudinal short-term study involving two groups of learners aged 13-14 years old (n=53). The results led us to…

The objective of the current study was to identify an effective learning environment for kindergarten students as they acquire an initial understanding of scientific inquiry activities (SIA) and a simple (idealized) scientific inquiry cycle (SIC). The study aimed to examine (a) the effects of instructional support and (b) the role of similarity…

This article introduces a flexible and easy-to-implement open-ended scientific inquiry activity called the Paper Towels Challenge. After experimentally determining which of three unbranded paper towels is the most absorbent, students discuss their results and methods. The teacher facilitates the discussion of epistemological issues. This activity…

In the present research, the "DNA Model with Clothespins" activity was designed to teach the subjects of nucleotide, DNA, and DNA replication, which are abstract subjects of science. The aim of the research, which was carried out with 20 students in 8th grade, was to examine the effects of the activity on students' achievement on the…

The purpose of this research is to examine the impact of activities based on scientific process skills on problem-solving skills of 4th grade students in science lessons. In the study a non-equivalent control group pre-test and post-test design type of quasi-experimental method was used. The research study group was composed of 30 students with 15…

This study examined the effect of using critical reading in scientific texts on students' academic achievement, sci-ence performance level and creativity. The study was conducted with 5th grade students in Eregli, Zonguldak during the 2017-2018 academic year. The study group consisted of a total of 34 students, 17 in the experimental group and 17…

In this work, different alternatives for locating the optimal feed stage in a distillation column as well as the effect of the feed temperature are studied, by solving a classroom problem. The results obtained permit us to select the best way to optimize the feed stage location as well as to detect what thermal feed phase conditions should be…

This study examined the impact of integrating virtual science inquiry activities with Predict-Observe-Explain (POE) teaching strategies on 5th graders' understanding of science concepts and epistemic beliefs in science. A cohort of 80 5th graders (mean age of 12 years old, 40 boys and 40 girls) from a public primary school in North China took part…

Students' out-of-school science participation has been identified as a factor that supports adaptive science outcomes. Researchers have largely investigated students' out-of-school science participation in terms of structured science activities (e.g., attending a science camp), with far less consideration of how students' involvement in…

Large numbers of U.S. students lack proficiency in science, and students from different ethnic and socioeconomic groups show disparities in science achievement. Science knowledge and skills are important for both academic and workplace success, and a variety of interventions have been developed to improve student achievement in science. The…

This study aims to reveal the effectiveness of the problem-based learning (PBL) model in teaching the concepts of heat, temperature and pressure, as well as the effect of the activities on the development of scientific process skills. For this purpose, the change in the academic achievement levels of the students constituting the sampling group…

My dissertation is a pre-mid-post-test, quantitative research design, including surveys and written assessments, to answer these research questions: 1. How do students' science mindset vary over time when engaged in science inquiry activities? Is there a difference between male and female students? 2. Is there a relationship between 7th grade…

For the possibility of using competitive tasks from the Biology Olympiad (BiO), either directly or after certain adaptations for everyday teaching tasks in the teaching process, it was aimed to determine if students could work meaningfully with them. The success of 2nd-year secondary school students (n = 113) in solutions of tasks (n = 5)…
