(AnNajah National University, 2025-12-31) Safa Ata Mohammad Nazzal
Abstract
This study explored the effect of integration of bioinformatics experiments within the eleventh-grade biology textbook on student's achievement and motivation in Palestine. A non -equivalent quasi-experimental approach was used to conduct the research. The research sample composed of (76) eleventh grade students within the experimental group who were subjected to bioinformatics activity based-intervention and (71) eleventh grade students within the control group. A validated biology achievement test and Biology Motivation Questionnaire (BMQ I) were used to assess student's achievement and motivation among both groups. Quade and two-way ANCOVA were used to analyze the achievement test scores while Bootstrapping ANCOVA was used to analyze BMQ scores. Results showed that the experimental samples had higher significant values of post achievement test scores compared to control sample post achievement test scores. In addition, two-way ANCOVA analysis revealed a significant difference of student's posttest scores due to the interaction of sample type along with learning environment and geographic location. However, no significant differences of student's post High Order Thinking Skills (HOTS) and post Low Order Thinking Skills (LOTS) scores were found due to the interaction of sample type with gender. In regards to students’ motivation, bootstrapping ANCOVA analysis revealed that the intervention had no significant effect on students BMQ total score and BMQ subscales in regards to sample type and gender.in addition, only intrinsic motivation, extrinsic motivation and self-relevance had a significant difference in regards to learning environment and geographic location within the experimental sample in favor to Qabatya school and face-to-face learning environment. Overall, the findings indicate that the intervention of bioinformatics experiments caused a positive effect on students’ cognitive capabilities but had no obvious significant effect on student's motivation. Further future studies are recommended to apply distinct bioinformatics-based intervention protocols that might enhance student's motivation while sustaining the observed achievement gains.

EFFECT OF Recycled PET PLASTIC ON THE MECHANICAL AND THERMAL PROPERTIES OF HOLLOW CONCRETE BLOCKS
(An Najah National University, 2025-11-16) Seifi, Majdi
The accumulation of plastic waste, particularly polyethylene terephthalate (PET), poses significant environmental issues due to its durability and detrimental degradation byproducts. The construction industry faces pressure to minimize reliance on natural resources like sand. Utilizing PET as a partial sand replacement in hollow concrete block production in Palestine presents a sustainable solution, reducing plastic waste and conserving natural aggregates.
This research investigated the impact of PET plastic waste as a partial fine aggregate (Sand) substitute in hollow concrete blocks, assessing different replacement ratios on compressive strength, unit weight, and thermal insulation. Four concrete mixtures were created with PET-to-sand replacement ratios of 0%, 10%, 15%, and 20% by weight. Shredded PET was sourced from post-consumer waste, and full-sized hollow blocks were cast. Testing evaluated compressive strength at 7 and 28 days, as well as block mass, specific weight, and thermal conductivity.
Increased PET content consistently decreased block weight while significantly enhancing thermal insulation. Thermal conductivity decreased from 1.12 to 0.47 W/m·°C, and R-values more than doubled. Compressive strength reduced at 10% and 15% PET but recovered at 20%, achieving 6.66 MPa at 28 days, similar to the control mix. PET-modified blocks showed brittle failure patterns. PET waste can be effectively reused in non-loadbearing hollow concrete blocks, enhancing thermal resistance and reducing weight while maintaining adequate strength, supporting sustainable building practices.

(An-Najah National University, 2025-10-23) Deek, Shatha
Current study used quasi-experimental design, to assess the effectiveness of expressive group art therapy in decreasing symptoms of depression, anxiety, and stress, and also in improving quality of life. (79) Students, aged between (7-12) years old were participated in the study. After conducting pre-test and post-test for both experimental and control groups, the results were collected and analyzed.
The findings have shown that symptoms of depression, anxiety, and stress for children in the experimental group decreased, and also in their quality of life has improved.
The findings highlighted the role of expressive group art therapy in decreasing symptoms of depression, anxiety, and stress for the study sample, and also in improving their quality of life. This therapeutic approach could be a valuable tool for parents, teachers, and mental health workers in supporting children’s mental health in risk areas.

الاحتراق النفسي وعلاقته بالحاجات النفسية الاساسية لدى لاعبي كرة القدم في المنتخب الفلسطيني للمحترفين
(جامعة النجاح الوطنية, 2025-10-14) Mahmoud, Bseso
هدفت الدراسة التعرف إلى مستوى الاحتراق النفسي والحاجات النفسية الأساسية لدى لاعبي الكرة القدم في الدوري الفلسطيني للمحترفين والعلاقة بينهما، وتحديد الفروق في الاحتراق النفسي والحاجات النفسية الأساسية لدى اللاعبين تبعاً لمتغيرات الخبرة في اللعب ومركز اللاعب وطبيعة اللاعب. ولتحقيق ذلك أجريت الدراسة على عينة عشوائية بسيطة قوامها (81) لاعباً، وتمثل العينة تقريباً (31%) من مجتمع الدراسة. استخدم الباحث المنهج الوصفي بصورته الارتباطية والتحليلية نظرًا لتناسبه مع طبيعة الدراسة وأهدافها. ولجمع البيانات تم استخدام مقياس الاحتراق النفسي كما ورد في دراسة (شطناوي والسعيدين، 2021) ومقياس الحاجات النفسية الأساسية (Deci & Rayan, 2000). ولمعالجة البيانات تم استخدام البرنامج الاحصائي (SPSS)
وأظهرت نتائج الدراسة أن مستوى الاحتراق النفسي والحاجات النفسية الأساسية لدى لاعبي الكرة القدم في الدوري الفلسطيني للمحترفين كان مرتفعاً، حيث كان متوسط الاستجابة عليهما على التوالي (3.69، 3.72). وأظهرت النتائج أيضاً أن توجد علاقة طردية دالة إحصائياً بين الاحتراق النفسي والحاجات النفسية الأساسية لدى اللاعبين، حيث كانت قيمة معامل الارتباط (0.80). وأخيراً، أظهرت النتائج أنه لا توجد فروق دالة إحصائياً في الاحتراق النفسي والحاجات النفسية الأساسية لدى اللاعبين تبعاً لمتغيري الخبرة في اللعب ومركز اللاعب، بينما كانت الفروق دالة إحصائياً في الاحتراق النفسي والحاجات النفسية لدى اللاعبين تبعاً لمتغير طبيعة اللاعب ولصالح (احتياط).
وأوصت الدراسة بعدة توصيات منها الاهتمام بإشباع وتلبية الحاجات النفسية الأساسية للاعبي المستوى العالي لكرة القدم من أجل تقليل احتراقهم النفسي.

EVALUATING THE EFFECTIVENESS OF A BEHAVIORAL REHABILITATION PROGRAM BASED ON NEUROPLASTICITY THEORY FOR DEVELOPING LIFE SKILLS, SELF-CARE, AND INDEPENDENCE IN PATIENTS WITH SCHIZOPHRENIA
(An-Najah National University, 2025-11-20) Kort, Nadeen Wael Jabra
This thesis investigates whether building a therapeutic program that combines Cognitive Behavioral Therapy (CBT) with neuroplasticity-based principles can help individuals with schizophrenia lead more independent lives. Schizophrenia often affects thinking, emotions, and social skills, and even the day-to-day basic tasks. Highlighting the effects of schizophrenia, participants took part in a program that integrated regular CBT sessions to speak about their thoughts and anxiety with activities specifically aimed at stimulating brain plasticity. A sample of this thesis is ten participants who were randomly assigned to either the combined experimental group or to a control group receiving the therapeutic program. Before the start of the program, we measured the LADL of the participants. Over 6 months, we measured the LADL again and used SPSS software to measure the effect of the program on their daily life, especially personal hygiene, medication management, social interaction, and self-care, along with decision-making and problem-solving abilities.
The results of this study reveal that the experimental group exhibited significant progress in various areas. They were more socially active and, hence, more capable of managing their daily routines, to an extent that their achievements were statistically superior to those in the control group. However, changes in diet awareness and social reasoning at a higher level barely occurred.
Besides, a few participants have kept reporting medication, induced increased appetite. The results thus provide the first signs that a combined method of psychological therapy and neuroscience might help patients to develop their everyday skills and regain some independence.
The researcher of this experiment underlines the importance of constant, guided assistance and points to the requirement for future studies that will aim at maintaining and further advancing these benefits over the long term.
