Conceptual difficulties experienced by introductory college biology students studying gene expression are explored in this empirical study. We used an open-ended assessment instrument and a pre-test/post-test design to measure prior knowledge and conceptual change over the course of one semester. Our findings suggest that introductory biology students struggle with the basic terminology necessary to understand complex biological systems at the molecular and genetic level. While conceptual growth from the beginning to the end of the semester was less than expected, learning gains were significant for all concepts examined by our assessment strategy. Qualitative evaluation of pre- and post-tests further highlighted the difficulty students have articulating their knowledge using scientific language. In our discussion, we emphasize the importance of assessing conceptual understanding, developing instructional strategies to promote conceptual change, and the need for closer alignment of curriculum between and within institutions. Ultimately, educational and institutional resources to support faculty development in the area of teaching and learning are critical for the retention and preparation of a diverse student population in the biological sciences.

The ability to interpret and reason from Tree of Life (ToL) diagrams has become a vital component of science literacy in the 21st century. This article reports on the effectiveness of a research-based curriculum, including an instructional booklet, laboratory, and lectures, to teach the fundamentals of such tree thinking in an introductory biology class for science majors. We present the results of a study involving 117 undergraduates who received either our new research-based tree-thinking curriculum or business-as-usual instruction. We found greater gains in tree-thinking abilities for the experimental instruction group than for the business-as-usual group, as measured by performance on our novel assessment instrument. This was a medium size effect. These gains were observed on an unannounced test that was administered ∼5–6 weeks after the primary instruction in tree thinking. The nature of students’ postinstruction difficulties with tree thinking suggests that the critical underlying concept for acquiring expert-level competence in this area is understanding that any specific phylogenetic tree is a subset of the complete, unimaginably large ToL.

The paper is about a study that investigated how the integration of assessment for learning enhances learning achievement among secondary school biology students in Tanzania. A quasi-experimental design involving pre-test and post-test of non-equivalent control and experimental groups was used to ascertain how the integration of assessment for learning into teaching and learning processes enhances students’ learning achievement. Two boarding secondary schools located in the suburbs of Dar Es Salaam were selected. Students in the two schools had maintained equivalent performances in national examinations in previous years. The results showed that the students taught using teaching and learning processes integrating assessment for learning outperformed those taught using conventional approaches. The integration of assessment for learning is likely to have contributed to the higher learning achievement in the experimental group. The study contributes to our understanding of how teachers in resource-constrained classrooms can integrate assessment for learning techniques into their day-to-day lessons, thereby harnessing the power of assessment to enhance learning and raise standards.

We aimed to contribute to a shift in higher education teaching and learning methods by considering problem-based learning (PBL) as an approach capable of positively affecting students from a geology and environment (GE) curricular unit. In a convenience sample from a Portuguese public university, two groups of students were defined: (1) an experimental group (n = 16), to which an intervention program (IP) based on PBL was applied, and (2) a comparison group (n = 17), subjected to the traditional teaching approach. For nine weeks, students subject to the IP faced four problem scenarios about different themes. A triangulation of methods was chosen. The study involved two phases: (1) qualitative (sustained on content analysis of driving questions raised by students, registered in a monitoring sheet) and (2) quantitative (quasi-experimental study, based on data from a prior and post-test knowledge assessment). The qualitative results point to the development of more complex cognitive-level questioning skills after increasing familiarity with PBL. The data obtained in the quantitative study, which included both a “within-subjects” and a “between-subjects” design, show higher benefits in the experimental group, documenting gains in terms of scientific knowledge when using the PBL methodology.

Recently, game-based multimedia development has been increasing rapidly. Game-based multimedia is not only used for entertaining but also for teaching and learning process. Meanwhile, for the majority of elementary school students, numeracy learning is still considered as a difficult subject to be learned and has not attracted students’ interest because it still uses vertical methods. The objective of this research is to examine the implementation of game-based multimedia in learning horizontal numeracy. In this game-based multimedia, horizontal numeracy material is presented in the form of a game. Horizontal numeracy material begins with addition, subtraction, multiplication, and division. Game-based multimedia is implemented to 20 students in grade 3 elementary schools in Bandung, Indonesia. Subsequently, the way students learn the materials and their learning outcomes are explored after using this multimedia. The results show that the students can learn horizontal numeracy excitingly; moreover, they can easily understand the concept of horizontal numeracy quickly. It is indicated by by the increasing of average post-test value.

This research is entitled “Using graphic organizer strategy in teaching writing on narrative paragraph (experimental research). Writing is a very important subject that should be learned by English learners. The students should be able to express their ideas and opinion either in the form of a sentence or paragraph. However, the researcher found that many students at the Second Grade Students of SMP Negeri 1 Tanah Luas could not express their ideas and develop into the paragraph. Hence, the appropriate strategy of teaching and learning is very important to help students master writing skills. This research aims to know the effect of achievement between the students who are taught writing by using graphic organizers from those taught writing in the narrative by using traditional methods. This research was experimental research and used a quasi-experimental design. The samples chosen in this research were the whole students of class VIII2 and VIII4 of SMPN 1 Tanah Luas. Class VIII2 consisted of 25 students was chosen as experimental group and class VIII4 consisted of 24 students was chosen as control group. This research was conducted in three phrases; there were pre-test, treatments and post-test. The data collection technique used in this research was test. The tests were pre-test and post-test. The researcher gave pre-test before giving treatment and post-test after giving treatment. The treatment was conducted in three meetings. The data was analyzed by using t-test formula. The research result and the hypothesis authentication found by using t-test formula in significant level 5% or α = 0.05 were obtained that ttest > ttable. The ttest found in this research was 3.91. Meanwhile, ttable was gotten from the list of distribution value with degree of freedom = 47, because the data not in the table, the researcher used interpolation approach and obtained = 1.67. So >  = 3.91 > 1.67. It meant that Ha was accepted and Ho was rejected. So, graphic organizer strategy significantly affects the students’ ability in mastering writing.   Kata Kunci: graphic organizer strategy, teaching and learning, writing narrative paragraph

Integrating the properties of computer algebra systems and dynamic geometry environments, Geogebra became an effective and powerful tool for teaching and learning mathematics. One of the reasons that teachers use Geogebra in mathematics classrooms is to make students learn mathematics meaningfully and conceptually. From this perspective, the purpose of this study was to investigate whether instruction with Geogebra has effect on students’ achievements regarding their conceptual and procedural knowledge on the applications of derivative subject. This study adopted the quantitative approach with pre-test post-test control group true experimental design. The participants were composed of two calculus classrooms involving 31 and 24 students, respectively. The experimental group with 31 students received instruction with Geogebra while the control group received traditional instruction in learning the applications of derivative. Independent samples t-test was used in the analysis of the data gathered from students’ responses to Applications of Derivative Test which was subjected to them before and after teaching processes. The findings indicated that instruction with Geogebra had positive effect on students’ scores regarding conceptual knowledge and their overall scores. On the other hand, there was no significant difference between experimental and control group students’ scores regarding procedural knowledge. It could be concluded that students in both groups were focused on procedural knowledge to be successful in learning calculus subjects including applications of derivative in both groups. On the other hand, instruction with Geogebra supported students’ learning these subjects meaningfully and conceptually.
